Abstract
To ensure therapeutic equivalence between the long-acting injectable (LAI) products, additional PK metrics other than Cmax and AUC were considered necessary. However, regarding the selection of additional PK metrics for bioequivalence (BE) assessment of exenatide LAI, a discrepancy existed between EMA's and USFDA's product-specific guidance. The EMA recommends that both the maximum plasma concentration in the initial-release phase (Cmax,1) and the extended-release phase (Cmax,2) should be determined. Nevertheless, the USFDA recommends the use of the partial area under the curve (i.e., the area under the curve from week 4 to the last sampling point; pAUC4w-t). The focus of this study was to compare the sensitivity of different PK metrics, including Cmax,1, Cmax,2, pAUC4w-t, early and late pAUC metrics truncated at different time points (three, four, five, six and seven weeks), to formulation-related parameters and pharmacodynamic (PD) markers of glycemic control. A sensitivity analysis was conducted using the published PK/PD model of exenatide LAI. The results indicated that Cmax,1 and Cmax,2 exhibited comparable sensitivities. AUC4w-t was sensitive to changes in detecting the differences in formulation-related parameters and PD markers of glycemic control, but did not provide superior sensitivity performance compared to Cmax,1 and Cmax,2. Among all tested PK metrics, AUC7w-t was found to be the most sensitive. The optimal cut-off time point for the pAUC should be set at the time of maximum plasma concentration in the extended-release phase (approximately 6-7 weeks). These results may provide useful insights into the selection of appropriate PK metrics for BE determination of exenatide LAI.

Abstract
OBJECTIVES Assess the bioequivalence of lacosamide extended-release (XR) capsules and immediate-release (IR) tablets and answer real-world clinical questions regarding the use of lacosamide XR. METHODS An open-label, randomized, two-treatment, two-sequence, oral comparative bioavailability study was conducted to assess the bioequivalence of two lacosamide formulations. Participants were randomized 1:1 to receive lacosamide XR capsules (400 mg once-daily) or IR tablets (200 mg twice-daily) in 1 of 2 sequences over 7-day periods. Primary outcome was the area under the lacosamide concentration-time curve over 24 h at steady-state (AUC0-τ,ss). Secondary outcomes were maximum (Cmax,ss) and minimum concentrations at steady-state (Cmin,ss). Bioequivalence was established when 90% confidence intervals (CIs) for geometric least square means ratios (GLSMs) were between 80% and 125%. Adverse events (AEs) and other safety outcomes were also assessed. Pharmacokinetic simulations, including adherent and partially adherent dosing scenarios with XR and IR formulations, modeled the clinical use of lacosamide XR. RESULTS Thirty-five healthy adult males were enrolled in the bioequivalence study. After 7 days of study drug, mean AUC0-τ,ss, Cmax,ss, and Cmin,ss values were similar between XR and IR formulations; all 90% CIs for GLSMs were between 80% and 125%. AEs were mild and no serious AEs or other clinically significant safety findings were observed. Pharmacokinetic simulations suggested that partial adherence affected formulations similarly; and the best strategy for switching formulations was to take the morning lacosamide IR dose followed by the evening lacosamide XR dose, as this resulted in the most consistent lacosamide plasma concentrations. CONCLUSIONS Once-daily lacosamide XR capsules were bioequivalent to twice-daily lacosamide IR tablets. Pharmacokinetic simulations indicated lacosamide XR and IR formulations were similarly affected by partial adherence, though once-daily dosing with lacosamide XR may offer clinical advantages, and formulations can be easily switched. These results support the use of lacosamide XR capsules as a once-daily alternative to lacosamide IR tablets.

Abstract
Capecitabine (CAP) is one of the fluoropyrimidine deoxynucleoside carbamates, which can be converted to 5-fluorouracil (5-FU) by thymine deoxynucleoside phosphorylase (dThdPase) to exert antitumor effects. The purpose of this study is to compare the pharmacokinetics (PK), bioequivalence (BE), and safety of two CAP tablets in Chinese patients with solid tumor cancer. The results showed that the geometric mean ratios (GMRs) of Cmax, AUC0-t and AUC0-∞ of CAP T/R reagent were 90.26%, 95.27%, and 95.07, respectively. The values and 90% confidence intervals (CI) of AUC0-t, AUC0-∞, and Cmax all fall within the range of 80.00-125.00%. In addition, a total of 22 subjects in this study had 30 adverse events, with an incidence of 45.83%, and there were no serious adverse events and adverse events that led to withdrawal from the trial.

Abstract
The Network on Bioavailability and Biopharmaceutics of EUFEPS (European Federation for Pharmaceutical Sciences) had organised an Open Discussion Forum on the ICH M13A draft "Guideline on bioequivalence for immediate-release solid oral dosage forms". This conference was cosponsored by the Arbeitsgemeinschaft Pharmazeutische Verfahrenstechnik (APV) and the Frankfurt Foundation Quality of Medicines. Scientists from academia and industry attended this workshop on May 15, 2023, in Frankfurt/Germany, to discuss the suggested regulations with the European members of the ICH drafting group. The aim of this report is to summarise and highlight the main discussion points such as choice of study population (females and/or males), request for fasted and/or fed studies, consequences of differences in drug product content, handling of aberrant plasma profiles and additional requirements in case of pH-dependant solubility. During the discussion important arguments were presented for a revision of certain requirements suggested in the draft guideline.

Abstract
Generic drugs are essential for affordable medicine and improving accessibility to treatments. Bioequivalence (BE) is typically demonstrated by assessing a generic product's pharmacokinetics (PK) relative to a reference-listed drug (RLD). Accurately estimating cutaneous PK (cPK) at or near the site of action can be challenging for locally acting topical products. Certain cPK approaches are available for assessing local bioavailability (BA) in the skin. Stimulated Raman scattering (SRS) microscopy has unique capabilities enabling continuous, high spatial and temporal resolution and quantitative imaging of drugs within the skin. In this paper, we developed an approach based on SRS and a polymer-based standard reference for the evaluation of topical product BA and BE in human skin ex vivo. BE assessment of tazarotene-containing formulations was achieved using cPK parameters obtained within different skin microstructures. The establishment of BE between the RLD and an approved generic product was successfully demonstrated. Interestingly, within the constraints of the current study design the results suggest similar BA between the tested gel formulation and the reference cream formulation, despite the differences in the formulation/dosage form. Another formulation containing polyethylene glycol as the vehicle was demonstrated to be not bioequivalent to the RLD. Compared to using the SRS approach without a standard reference, the developed approach enabled more consistent and reproducible results, which is crucial in BE assessment. The abundant information from the developed approach can help to systematically identify key areas of study design that will enable a better comparison of topical products and support an assessment of BE.

Abstract
INTRODUCTION To help prevent febrile neutropenia, pegfilgrastim-cbqv (UDENYCA®; Coherus BioSciences), a pegfilgrastim (NEULASTA®; Amgen) biosimilar, is administered 24-96 h after myelosuppressive chemotherapy. Delivery of pegfilgrastim-cbqv using an on-body injector (OBI) provides an alternative method of administration, affording options in drug delivery. This study aimed to establish pharmacokinetic (PK) and pharmacodynamic (PD) bioequivalence and assess the safety of pegfilgrastim-cbqv administered using an OBI compared with a prefilled syringe (PFS). METHODS In this open-label, two-period crossover study, healthy adult male participants (N = 189) were randomly assigned 1:1 to receive pegfilgrastim-cbqv 6 mg subcutaneously using an OBI (n = 92) or a PFS (n = 95) in period 1 and then an injection via the other method in period 2. Primary PK end points were area under the concentration-time curve from time 0 to infinity, area under the concentration-time curve from time 0 to the last quantifiable concentration, and maximum plasma concentration. Secondary PD end points, safety, immunogenicity, and tolerability were also assessed. RESULTS The 90% confidence intervals (CIs) of the geometric mean ratios for the PK and PD end points fell within the predetermined range (80-125%), indicating PK and PD bioequivalence between pegfilgrastim-cbqv OBI and pegfilgrastim-cbqv PFS. Treatment-emergent adverse events (TEAEs) occurred in 87.8% and 75.8% of participants in the OBI and PFS groups, respectively. Most TEAEs were musculoskeletal effects. The most common OBI-related TEAE was injection site erythema (31.7%), which was mild, transient, and self-limiting. The incidence of treatment-emergent antidrug antibodies (ADAs) was similar between the OBI and PFS. ADAs had no apparent impact on PK, PD, or safety. Neutralizing antibodies were not detected in any participant. CONCLUSIONS Results of the study showed PK and PD bioequivalence of pegfilgrastim-cbqv administered using OBI compared with PFS. OBI and PFS administration had similar safety, tolerability, and immunogenicity profiles. No unexpected safety signals were identified. Graphical Abstract available for this article.

Abstract
PURPOSE SUVN-1105 is a novel formulation of abiraterone acetate which was developed to demonstrate improved bioavailability, compared to Zytiga and Yonsa, and to reduce the dose and eliminate the food effect. A Phase 1 study was conducted to assess the bioequivalence, food effect, and comparative pharmacokinetics of SUVN-1105 to Zytiga in healthy male subjects. METHODS The study comprised of 2 segments. Segment 1 was a single-center, 4-period crossover, open-label, fixed treatment sequence, single-dose study to evaluate the safety and pharmacokinetics of SUVN-1105 (N = 12 subjects per period). Segment 2 was a single-center, open-label, single-dose, randomized, 4-period, 4-treatment, 4-sequence crossover study to evaluate bioequivalence and comparative pharmacokinetics of SUVN-1105 against Zytiga (N = 44) under overnight fasted, modified fasted, and fed conditions. RESULTS Abiraterone exposures appeared to increase proportionately with SUVN-1105 dose (200 mg vs. 250 mg) in Segment 1. In Segment 2, abiraterone exposures of 250 mg SUVN-1105 in the fasted or fed conditions were higher than those of Zytiga 1000 mg in the overnight fasted conditions. Abiraterone exposures of 250 mg SUVN-1105 decreased in the fed conditions (64% and 29% decrease in Cmax and AUC, respectively) compared to overnight fasted conditions. CONCLUSIONS The abiraterone exposures of 250 mg SUVN-1105 in the fasted or fed conditions fall within the abiraterone exposures of 1000 mg Zytiga in fasted and modified fasted conditions. Single doses of SUVN-1105 were safe and well-tolerated in healthy males both in the fasted and fed conditions.

Abstract
This bioequivalence study was conducted to evaluate two oral formulations of cotrimoxazole tablets in healthy Chinese subjects. All 26 subjects recruited to this study were randomly and evenly classified into two groups and received a single dose (sulfamethoxazole: 400 mg and trimethoprim: 80 mg) of test cotrimoxazole tablets (generic drug) or reference cotrimoxazole tablets (branded drug). After a 7-day washout period, these subjects received one dose of reference drug or test drug. Blood samples were collected from participants before and up to 48 h after dosing to assess the concentration of sulfamethoxazole (SMX) and trimethoprim (TMP) in plasma and a plasma concentration-time curve was drawn. Then, the pharmacokinetics parameters were calculated accordingly. Our data revealed that there were no significant differences observed in the maximum plasma concentration (Cmax), area under the curve from time 0 to the last measurable concentration (AUC0-t), and area under the curve from time 0 to infinity (AUC0-∞) between the two formulations. For SMX, the 90% confidence intervals (CI) of the geometric mean ratio for Cmax, AUC0-t, and AUC0-∞ were 104.03-113.92%, 100.46-103.70%, and 100.41-103.81%, respectively. Similarly, for Trimethoprim (TMP), the 90% CI ranged from 98.54 to 106.95% for Cmax, from 99.31 to 107.68% for AUC0-t, and from 99.49 to 107.55% for AUC0-∞. Importantly, all these 90% CI values fell within the range of 80.00-125.00%, indicating that the test drug is bioequivalent to the reference drug. Furthermore, throughout the entire trial, no suspected serious adverse events were reported, indicating the safety profile of the newly developed generic cotrimoxazole. In summary, our study demonstrates that the newly developed generic formulation of cotrimoxazole is bioequivalent to the branded formulation under fasting conditions.

Abstract
In the century of precision medicine and predictive modeling, addressing quality-related issues in the medical supply chain is critical, with 62 % of the disruptions being attributable to quality challenges. This study centers on the development and safety of liposomal doxorubicin, where animal studies alone often do not adequately explain the complex interplay between critical quality attributes and in vivo performances. Anchored in our aim to elucidate this in vitro-in vivo nexus, we compared TLD-1, a novel liposomal doxorubicin delivery system, against the established formulations Doxil® and Lipodox®. Robust in vitro-in vivo correlations (IVIVCs) with excellent coefficients of determination (R2 > 0.98) were obtained in the presence of serum under dynamic high-shear conditions. They provided the foundation for an advanced characterization and benchmarking strategy. Despite the smaller vesicle size and reduced core crystallinity of TLD-1, its release behavior closely resembled that of Doxil®. Nevertheless, subtle differences between the dosage forms observed in the in vitro setting were reflected in the bioavailabilities observed in vivo. Data from a Phase-I clinical trial facilitated the development of patient-specific IVIVCs using the physiologically-based nanocarrier biopharmaceutics model, enabling a more accurate estimation of doxorubicin exposure. This advancement could impact clinical practice by allowing for more precise dose estimation and aiding in the assessment of the interchangeability of generic liposomal doxorubicin.

Abstract
PURPOSE The poly (ADP-ribose) polymerase inhibitor niraparib is indicated as maintenance treatment in patients with certain subtypes of advanced ovarian cancer, and is being investigated in patients with other solid tumors. Niraparib is available in 100-mg capsules with a starting dosage of 200 or 300 mg/d. This study assessed the relative bioavailability (BA) and bioequivalence (BE) between a 1 × 300-mg tablet relative to 3 × 100-mg niraparib capsules. In addition, the food effect (FE) of a high-fat meal on the pharmacokinetic (PK) properties of tablet-formulated niraparib was investigated. METHODS This was a US-based, 3-stage, open-label, multicenter, single-crossover, randomized-sequence study. Enrolled patients were 18 years and older, with histologically or cytologically confirmed advanced solid tumors (metastatic or local) and disease progression despite standard therapy. Patients were randomly assigned 1:1 to receive niraparib 1 × 300-mg tablet or 3 × 100-mg capsules in the BA and BE stages or 1 × 300-mg tablet in a fasted or fed (high-fat meal) state in the FE stage. Across all study stages, PK parameters were assessed for 7 days after each dose (tablet or capsule) or prandial state (fasted or fed). In the BA stage, patients crossed over to the other treatment after a 7-day washout period, which was extended to 14 days in the BE and FE stages. Tolerability was assessed for patients who received any amount of niraparib. FINDINGS The BA-, BE-, and FE-evaluable populations comprised 23, 108, and 19 patients, respectively, who completed both treatment periods in each study stage, had sufficient concentration data to accurately estimate PK parameters without niraparib carryover, and did not experience disqualifying events. PK parameters were similar after dosing with tablet or capsule formulations; the 90% CIs of the geometric least square means for Cmax, AUC0-t, and AUC0-∞ were within the 0.80 to 1.25 BE limits. In the FE stage, Cmax, AUC0-t, and AUC0-∞ were 11%, 32%, and 28% higher, respectively, in the fed versus fasted state. The safety population included 29, 168, and 28 patients in the BA, BE, and FE stages, respectively, who received niraparib. No new safety signals were identified. IMPLICATIONS Niraparib tablets were found to be bioequivalent to capsules. A modest (≤32%) FE was observed with a high-fat meal, but was not considered to be clinically meaningful, given niraparib's PK variability. CLINICALTRIALS gov identifier: NCT03329001.

Abstract
Based on our experiences in bile acid profiling, this work developed and validated a liquid chromatography electrospray ionization tandem mass spectrometry method to separate endogenous bile acid isomers and quantitatively determine ursodeoxycholic acid (UDCA), glycoursodeoxycholic acid (GUDCA) and tauroursodeoxycholic acid (TUDCA) in human plasma. The separation was performed on a CORTECS C18 column with the mobile phase consisting of 1.0 mM ammonium acetate and acetonitrile-methanol (80:20, v/v). UDCA, GUDCA and TUDCA were detected in the negative mode on a triple-quadrupole mass spectrometer at the ion transitions of m/z 391 > 391, m/z 448 > 74, m/z 498 > 80, respectively. Phosphate buffer was employed as the surrogate matrix to establish the isotope internal standard corrected calibration curves of analytes. The background-method with a linearity range of 10-200 ng/mL was partially validated to determine the endogenous levels of analytes in blank human plasma, which was incorporated into the validation of bioequivalence-method with a linearity range of 50-10000 ng/mL. The bioequivalence (BE)-method was fully validated with special focus on matrix effects, which have been critically evaluated using the precision and accuracy of quality control samples prepared from the blank human plasma of 12 individuals. It is disclosed for the first time that the BE results of UDCA formulation may yield false results when the method is insufficient to separate UDCA from isoursodeoxycholic acid, a microbial metabolite of both endogenous and exogenous UDCA. The present method has established a milestone for the evaluation of UDCA formulations and is expected to provide a valuable reference for the bioanalytical development of endogenous medicinal products.

Abstract
Albuvirtide (ABT) is the first long-acting HIV fusion inhibitor developed in China, blocking the invasion of HIV-1 virus into target cells. This study aimed to compare the pharmacokinetics (PK), tolerability, and safety of ABT following a single intravenous (IV) bolus injection or intravenous drip in healthy Chinese subjects. A single-center, randomized, open-label, single-period, parallel phase I clinical trial was conducted. Thirty subjects were randomly divided into three groups in a ratio of 1:1:1. After an overnight fast, all subjects received a single dose of 320 mg ABT either by intravenous drip for 45 min (group A) or bolus injection for 0.5 min (group B), or bolus injection for 3 min (group C). ABT plasma concentrations were analyzed using a validated enzyme-linked immunosorbent assay (ELISA). Non-compartmental analysis was used to evaluate PK parameters. The median time to reach maximum concentration was 0.75 h in group A and 0.16 h in both groups B and C. Elimination half-life, mean residence time, apparent clearance, and apparent volume of distribution were similar among the three groups. The 90% confidence intervals (CI) of geometric mean ratios of PK parameters for groups B and C relative to group C were within 85-120%. All adverse events (AEs) reported in this study were mild, according to the CTCAE guidelines and the study investigator's judgement. ABT bolus injections for 0.5 min and 3 min are expected to be well tolerated and to exhibit similar PK characteristics as IV drip for 45 min, offering potential clinical benefits.

Abstract
Over the past few decades, physiologically based biopharmaceutics modeling (PBBM) has demonstrated its utility in both new drug and generic product development. Applications of PBBM for fed bioequivalence study waivers is an upcoming area. Recently Innovation & Quality (IQ) consortium demonstrated utility of PBBM to avoid repeat food effect studies for new drugs. In the similar lines, the current manuscript aims to discuss role of PBBM in generic fed bioequivalence study waivers. Generic industry practices related to PBBM model development to predict fed bioequivalence was portrayed with special emphasis on fed bio-predictive media. Media that can simulate fed bioequivalence study outcome were discussed from practical perspective. In-depth analysis, collating the data from 36 products was performed to understand predictability of PBBM for fed bioequivalence. Cases where PBBM was successful to predict fed bioequivalence was correlated with BCS class, formulation category and type of food effect. Further, two case studies were presented wherein fed bioequivalence study waiver obtained with PBBM approach. Lastly, future direction in terms of fed bioequivalence study waivers, regulatory perspectives and best practices for PBBM were portrayed. Overall, this article paves a way to utilize PBBM for generic fed bioequivalence study waivers.

Abstract
A derivatization-free hydrophilic-interactive chromatography-mass spectrometry (HILIC-MS/MS) method was developed for quantifying low levels of alendronate in human plasma. Alendronate was separated and concentrated using calcium co-precipitation and analyzed by HILIC-MS/MS, requiring only a 300 μL plasma sample for each analysis. The method is simpler, safer, and more environmentally friendly than the conventional LC-MS/MS method that requires solid-phase extraction and derivatization steps during sample pretreatment. The method was validated for selectivity, linearity, precision, accuracy, extraction recovery, matrix effect and limit of quantification. The between-run precisions were no more than 7.1 % with accuracy ranging from - 1.7-6.3 %; extraction recovery was determined to be 85.3 %; while validation results indicated that the method was suitable for accurately quantifying alendronate concentrations in the range from 0.2 to 50 ng/mL. The approach was used successfully for high throughput analysis of alendronate in more than 3700 plasma samples from 120 subjects in a bioequivalence study.

Abstract
PURPOSE This article describes the clinical development bridging strategy and key data to support the marketing application of the risankizumab on-body injection (OBI) system for the treatment of moderately to severely active Crohn's disease (CD), even though the OBI was not evaluated directly in the pivotal Phase III studies in CD. METHODS Three studies were conducted as part of the clinical bridging strategy. The pilot pharmacokinetics (PK) study was a Phase I, single-dose, 4-arm, open-label, randomized, parallel-group exploratory PK and tolerability study that assessed the effect of rate and volume of administration on the bioavailability (BA) of risankizumab and the extent of injection site-related pain after subcutaneous (SC) administration in healthy subjects. The pivotal BA/bioequivalence (BE) study was a relative BA/BE bridging study in healthy subjects to assess the relative BA of the to-be-marketed risankizumab OBI compared with the prefilled syringe (PFS) used in the Phase III CD studies. The OBI adhesive study was a randomized, open-label, non-drug interventional study in healthy subjects to assess the OBI adhesive effectiveness and skin tolerability at 2 different locations (abdomen and upper thigh) over different periods of time (5 and 30 minutes). FINDINGS The pilot PK study showed that risankizumab exposures were similar across different rates/volumes of SC administration in healthy subjects, thereby supporting further development of the OBI. Second, a pivotal BA/BE study showed comparability between the OBI and Phase III PFS with bioequivalent risankizumab AUCs and no clinically meaningful difference for Cmax based on the wide therapeutic window of risankizumab. In both studies, no new safety risks were identified. No impact of immunogenicity on PK profile or safety was observed for the OBI. Third, an adhesive OBI (without risankizumab) study showed that there were no differences in adhesion/skin tolerability observed over time (up to 30 minutes) or for location of adhesion, and the OBI device adhesion was well tolerated at both the abdomen and thigh locations. IMPLICATIONS These results supported the risankizumab OBI presentation approval in CD.

Abstract
This study aimed to develop a dissolution test that can predict the bioequivalence (BE) of enteric-coated pellet formulations. The original duloxetine hydrochloride capsule (reference formulation (RF); Cymbalta® 30 mg capsule) and four generic test formulations (two capsules (CP) and two orally disintegrating tablets (OD)) were used as model formulations. Clinical BE studies were conducted on 24-47 healthy male subjects under fasting conditions. Dissolution tests were performed using a compendial paddle method (PD) (paddle speed: 50 rpm) and a flow-through cell method (FTC) (flow rate: 4 mL/min). For a further test, cotton balls were added to the vessel to apply gentle mechanistic stress to the formulations, and paddle speed was reduced to 10 rpm (paddle with cotton ball method (PDCB)).All the dissolution tests were conducted with 0.01 M HCl (pH 2.0) for 0.5 h followed by 10 mM bicarbonate buffer solutions (pH 6.5) for 4 h. One each of the two CP and two OD showed BE with RF. PDCB was able to discriminate between BE and non-BE formulations, while this was not possible with PD and FTC. In PDCB, the cotton balls intermittently moved the pellets near the vessel bottom. PDCB is useful for predicting BE during formulation development.

Abstract
BACKGROUND To demonstrate bioequivalence between two drug formulations, a pilot trial is often conducted prior to a pivotal trial to assess feasibility and gain preliminary information about the treatment effect. Due to the limited sample size, it is not recommended to perform significance tests at the conventional 5% level using pilot data to determine if a pivotal trial should take place. Whilst some authors suggest to relax the significance level, a Bayesian framework provides an alternative for informing the decision-making. Moreover, a Bayesian approach also readily permits possible incorporation of pilot data in priors for the parameters that underpin the pivotal trial. METHODS We consider two-sequence, two-period crossover designs that compare test (T) and reference (R) treatments. We propose a robust Bayesian hierarchical model, embedded with a scaling factor, to elicit a Go/No-Go decision using predictive probabilities. Following a Go decision, the final analysis to formally establish bioequivalence can leverage both the pilot and pivotal trial data jointly. A simulation study is performed to evaluate trial operating characteristics. RESULTS Compared with conventional procedures, our proposed method improves the decision-making to correctly allocate a Go decision in scenarios of bioequivalence. By choosing an appropriate threshold, the probability of correctly (incorrectly) making a No-Go (Go) decision can be ensured at a desired target level. Using both pilot and pivotal trial data in the final analysis can result in a higher chance of declaring bioequivalence. The false positive rate can be maintained in situations when T and R are not bioequivalent. CONCLUSIONS The proposed methodology is novel and effective in different stages of bioequivalence assessment. It can greatly enhance the decision-making process in bioequivalence trials, particularly in situations with a small sample size.

Abstract
Introduction Withania somnifera (WS) or ashwagandha is an adaptogenic plant used extensively in traditional medicines and as a food supplement. Despite a long history of use and numerous clinical trials, the human pharmacokinetics of withanolides, the active phytochemicals in WS extracts, have not been fully evaluated. This study evaluated the oral pharmacokinetics and bioequivalence of active withanolides in human plasma after administration of a single dose of two commercial ashwagandha extracts containing equal amounts of total withanolides. Methods This randomized, double-blind, single-dose crossover study of 16 healthy human volunteers evaluated the acute oral bioavailability of withanolides and the bioequivalence of two WS extracts, WS-35 and WS-2.5. WS-35 was standardized to total withanolides not less than 40% comprising not less than 35% withanolide glycosides and WS-2.5 was standardized to 2.5% withanolides. The clinical dosages were normalized to 185 mg of total withanolide in each extract at the bioequivalent dosages. The pharmacokinetic parameters of withanolide A, withanoside IV, withaferin A, and total withanolides were quantified in the blood plasma using a validated LC-MS/MS method. Results The half-life, C-max, and mean residence time of the total withanolides were 5.18, 5.62 and 4.13 times significantly higher and had lower systemic clearance with WS-35 than with WS-2.5 extract. Considering the plasma AUC 0-inf of total withanolides per mg of each WS extract administered orally, WS-35 was 280.74 times more bioavailable than WS-2.5. Conclusion The results of this study highlight the importance of withanolide glycosides in improving the pharmacokinetics of WS extracts. Owing to its superior pharmacokinetic profile, WS-35, with 35% withanolide glycosides, is a promising candidate for further studies on Withania somnifera.

Abstract
OBJECTIVE A mycophenolate sodium enteric-coated tablet has shown a satisfying anti-rejection effect in patients receiving solid organ transplantation. The current study evaluated the bioequivalence between the test (Ruiyirong®) vs. reference (Myfortic®) formulations by exploring equations for predicting their area under the concentration-time curve (AUC) using a limited sampling strategy in healthy subjects. METHODS Forty-eight healthy Chinese subjects were randomized into three administration sequences (test-reference-reference, reference-reference-test, and reference-test-reference) to receive the Ruiyirong or Myfortic treatment on days 1, 8, and 15. RESULTS The 90% confidential interval (CI) of the geometric mean ratios (test/reference) of maximum plasma concentration (Cmax), the AUC from time 0 to the last timepoint (AUC0-t), and the AUC from 0 to infinity (AUC0-∞) was 92.90%-110.57%, 96.91%- 101.80%, and 96.71%-101.84%, respectively. All these values fell into the bioequivalence criteria of 80.00%-125.00% (based on the criteria of the Food and Drug Administration). The adverse events were 10.4% in Ruiyirong test group and 14.6% in Myfortic reference group. Eight equations for estimating the AUC of the Ruiyirong test and Myfortic reference formulations were evaluated; most of them worked well with the R-value >0.8. Among the four chosen equations, the intragroup verification exhibited a high agreement with the R-value ranging from 0.857 to 0.971 and with the low predictive error (PE > 5% with absolute PE > 15%). Meanwhile, the intergroup verification indicated a high inter-agreement with the R-value ranging from 0.896 to 0.974 (all P < 0.001). CONCLUSION The Ruiyirong test vs. Myfortic reference formulations meet the bioequivalent criteria and are well tolerated. The further linear regression analysis explores eight equations predicting the AUC value and the chosen four equations for the Ruiyirong test and Mayfortic reference formulations are interchangeable.

Abstract
OBJECTIVE The demand for generic tacrolimus is enormous. Our randomized trial was an open-label single-dose testing with four-periods and two-sequences; we aimed to evaluate the bioequivalence between a generic and branded tacrolimus by establishing their area under concentration-time curve (AUC) predictive equations. For better comparison, each tacrolimus served either as test vs. reference in sequence 1 or vice versa as reference vs. test in sequence 2. METHODS Forty healthy subjects were randomized into two groups, namely a sequence 1 group (N = 20 in test-reference-test-reference) or sequence 2 (N = 20, reference-test-reference-test) received a test tacrolimus (Ruibeirong®; Chengdu Shengdi Medicine Co., Ltd.) and a reference tacrolimus (Astagraf XL®, Astellas Ireland Co., Ltd.) under the fasting condition with a wash-out period of ≥14 days between every two phases. Blood samples were collected sequentially until 120 h after oral administration of tacrolimus. RESULTS A 95% upper confidence bound was -0.05% for the peak concentration (Cmax), -0.02% for the AUC from 0 to the last time point (AUC0-t), and - 0.02% for the AUC from 0 to infinity (AUC0-∞). The geometric least square means ratio (test/reference) with 90% of confidence interval (CI)) was 96.10% (90.58%-101.95%) for Cmax, 93.80% (88.52%-99.39%) for AUC0-t, and 94.34% (89.20%-99.77%) for AUC0-∞. Meanwhile, the ratio of within-subject standard deviation of test/reference (σWT/WR) with 90% CI was 0.66 (0.50-0.86) for Cmax, 0.73 (0.55-0.96) for AUC0-t, and 0.75 (0.57-0.98) for AUC0-∞. These results fulfilled the bioequivalence criteria by the Food and Drug Administration. Both products showed acceptable safety. Moreover, the AUC predictive equations (by linear regression plus limited sampling strategy) with 2-5 sampling time point showed the high performance (all R > 0.970, predictive error (PE) >0.5%, absolute PE <5.1%, which were interchangeable between test and reference products. CONCLUSION Generic tacrolimus (Ruibeirong®) is bioequivalent to branded tacrolimus (Astagraf XL®) with tolerable safety, which AUC predictive equations work well and are interchangeable between the two products.

Abstract
The prediction of intestinal absorption of various drugs based on computer simulations has been a reality. However, in vivo pharmacokinetic simulations and virtual bioequivalence evaluation based on GastroPlus™ have not been found. This study aimed to simulate plasma concentrations with different dissolution profiles and run population simulations to evaluate the bioequivalence of test and reference products of atorvastation using GastroPlus software. The dissolution profiles of the reference and test products of atorvastatin (20 mg tablets), and clinical plasma concentration-time data of the reference product were used for the simulations. The results showed that the simulated models were successfully established for atorvastatin tablets. Population simulation results indicated that the test formulation was bioequivalent to the reference formulation. The findings suggest that modelling is an essential tool to demonstrating the possibility of pharmacokinetic and bioequivalence for atorvastatin. It will contribute to understanding the potential risks during the development of generic products.

Abstract
The series of conferences of the Global Bioequivalence Harmonisation Initiative (GBHI) was started in 2015 by the European Federation for Pharmaceutical Sciences (EUFEPS). All GBHI meetings so far were co-organised together with the American Association of Pharmaceutical Scientists (AAPS). Beginning with the 3rd workshop US-FDA joined as co-sponsor - to support global harmonisation of regulatory recommendations for bioequivalence (BE) assessment. At the 5th GBHI conference, the following BE topics were intensively discussed, and the following main conclusions were drawn: (1) Statistical considerations for BE assessment in specific situations covering scaling approaches for highly variable drug (HVD) products, two-stage adaptive design and opportunities of modelling and simulation to support BE: even though special BE study concepts like adaptive designs are not often used in practise so far, a majority of the workshop participants were in favour of a more frequent application of such approaches. The regulatory conditions relevant in this context need further concretisation and harmonisation between the regions. Moreover, modelling and simulation were considered as a promising and evolving approach, also for BE development programmes. (2) Fed versus fasting conditions in BE trials: Findings that BE between generic products could be confirmed only after fasted administration but failed under fed conditions seem more an exception than the rule. Obviously, BCS class IV compounds are most problematic in this context. Differences in critical excipients such as surfactants or pH-modifiers may be relevant reasons for different sensitivity for interactions in fasted versus fed conditions. Consequently, such deviations in composition of generic preparations should be avoided. Moreover, confirmation of BE may be generally difficult comparing different dosage forms, such like capsules versus tablets, especially in fed state. (3) BE assessment of locally acting drug products applied topically to the skin: Appropriateness and potential benefit of in-vitro tests as alternatives to clinical efficacy studies have been comprehensively discussed. In addition to the already well-established in-vitro release and permeation tests, other techniques were suggested, e.g., Raman spectroscopy or dermal open flow microperfusion. Validation of those methods is challenging and, despite significant progress already achieved during previous years, more research is needed before they may be fully accepted for regulatory purposes. (4) BE evaluation of narrow therapeutic index (NTI) drugs: The discrepancies amongst regulatory agencies in necessity of tighter BE acceptance ranges, the recommendations for inclusion of peak and total drug exposure into BE assessment with more restrictive criteria and the importance of comparison of the product-related within-subject variability for NTI drugs were debated. Arguments in favour and against the different approaches were presented and discussed but need further consideration before harmonisation can be achieved. The highly interactive meeting and extensive exchange between regulators and scientists from industry and academia resulted in useful progress in open BE issues and supported the goal of science-driven harmonisation.

Abstract
Objective To investigate the Bioequivalence of Anplag® 90mg (Ticagrelor) tablet and Brilinta® 90 mg (Ticagrelor) tablet under fasting conditions in healthy Pakistani subjects. Method This was an open-label, cross-over, randomized, single-dose, two-period, single-center Bioequivalence Study conducted at Center of Bioequivalence Studies and Clinical Research (CBSCR), ICCBS, University of Karachi, Karachi, Pakistan from September 2020 to January 2021. This was an open-label, randomized, single-dose, two-period, cross-over Bioequivalence Study. After randomization, a single dose of Ticagrelor 90mg tablet (test or reference drug) were administered orally in 1:1 ratio to each subject under fasting conditions. Seven days washout period was kept between the two periods in order to avoid carry over. Blood samples were then taken up to 48th hours post-dose. Point estimates and 90% confidence intervals (CI) for the ratio of the log-transformed values were calculated. Bioequivalence assessment of both, the reference and the test drugs were based on the primary Pharmacokinetic PK metrics including peak maximum concentration (Cmax), area under the curve (AUC) from zero to last quantifiable concentration (AUClast), and AUC from zero to infinity (AUCtotal) after log-transformation of data with ANOVA. In this bioequivalence study, the primary pharmacokinetic parameters were assessed for both Ticagrelor and its Active Metabolite (AR-C124910XX). Safety endpoints were evaluated by monitoring adverse events (AEs). Results The 90% Confidence Intervals (CIs) of the Geometric Mean Ratio for primary PK parameters including Cmax, AUClast, and AUCtotal all were within the accepted bioequivalence range of 80%- 125%. In the current study, no serious adverse events were reported. Conclusion Our results showed that the two tested formulations of Ticagrelor tablets were bioequivalent and well tolerated.Trial Registration: ClinicalTrials.gov Identifier: NCT04941196.

Abstract
INTRODUCTION Pegfilgrastim-cbqv (UDENYCA®; Coherus BioSciences, Redwood City, CA, USA) is a pegfilgrastim (Neulasta®; Amgen, Thousand Oaks, CA, USA) biosimilar approved for administration by prefilled syringe (PFS). The recently approved pegfilgrastim-cbqv prefilled autoinjector (AI) was developed as another method of self-administration and to aid in-office use, providing flexibility in drug delivery. The objectives of the study were to assess the pharmacokinetics (PK) and pharmacodynamics (PD) to determine bioequivalence of the prefilled AI and the PFS for administration of pegfilgrastim-cbqv and to assess the safety profile of the prefilled AI. METHODS During this open-label, two-period crossover study, healthy adult males (N = 155) were randomly assigned (1:1 ratio) to receive a subcutaneous injection of pegfilgrastim-cbqv using a prefilled AI (n = 76) or a PFS (n = 79) in period 1. During period 2, participants received an injection using the other method. Primary PK and secondary PD parameters were calculated to assess the bioequivalence of the treatment as administered by the two delivery methods. Safety and immunogenicity were also assessed. RESULTS The 90% CIs of the geometric mean ratios for the PK and PD parameters were within the required range (80-125%), demonstrating bioequivalence between the pegfilgrastim-cbqv prefilled AI and PFS. Treatment-emergent adverse events (TEAEs) were reported by 75% and 74.1% of participants in the prefilled AI and PFS groups, respectively. The most common TEAEs in both treatment groups were myalgia, bone pain, and headache. AI-device-related TEAEs were injection site pain (1.4%) and injection site bruising (0.7%). The incidence of antidrug antibodies and neutralizing antibodies was low and was similar in both treatment sequences. CONCLUSIONS The bioequivalence of pegfilgrastim-cbqv administered using a prefilled AI and a PFS was established. The safety, including immunogenicity profiles, of pegfilgrastim-cbqv administered using the prefilled AI and the PFS were similar, with no new safety findings.

Abstract
Background Epilepsy is a common global neurological disorder. About 30% of epileptic patients are managed with anti-epileptic Drugs (AEDs). Since 2000, Levetiracetam (LEV) has been marketed around the world as an AED under the brand name Keppra, and recently more generics are found in the Saudi market as cheaper alternatives. The objective of this study is to evaluate the bioequivalence of LEV brand and generics available in the Saudi market in mice. Methods Pharmacokinetics (PK), liver function test, and behavioral studies were conducted for LEV brand and generic in different groups of Blab/c mice. Results PK results show a significance difference in PK parameters mostly evidenced with generic 3, then generic 2. The only significant different between Keppra and generic 1 was in T1/2. In addition, Keppra did not significantly increase liver enzymes in comparison to other generics. On the other hand, other generics showed less favorable results in increasing liver enzymes. Keppra reduced the number and intensity of epileptic attacks, had no mortality rate due to epilepsy, and was associated with less sever seizures attacks. Conclusion Keppra, the brand form of LEV, has better safety and efficacy profiles in mice compared to 3 generics found in the Saudi market. Therefore, we recommend evaluating the same parameters tested in this study in patients utilizing similar generics and brand to establish the existence of bioequivalence between LEV brand and generics.

Abstract
OBJECTIVE Bioequivalence (BE) studies support the approval and clinical use of both new and generic drug products. Narrow therapeutic index (NTI) drugs have relatively high costs and low success rates of BE evaluation clinical trials as high-risk drugs. A physiologically-based pharmacokinetic (PBPK) model can be used to evaluate the BE of two preparations. METHODS This study inputs the basic physical and chemical property parameters of warfarin sodium available at the present stage into GastroPlus™ software, and combined it with the Advanced Compartmental Absorption and Transit (ACAT™) model built into the software. The PBPK model of Chinese individuals taking 2.5 mg of warfarin sodium orally while fasted condition was developed using the disposal parameters calculated from the clinically measured PK data of the reference preparations. The model was tested using the PK data of other reference preparations and tested preparations from different domestic manufacturers. RESULTS The results revealed that at least 30% of drugs are released in 30 min under a pH of 4.5 condition, and at least 80% are released in 30 min under a pH of 6.8 condition, which can be used as bioequivalent dissolution limits under fasted conditions. The risk of BE failure in the fed condition will be significantly reduced for the clinical study on the BE of warfarin sodium, which is a NTI drug if the fasted condition is bioequivalent. CONCLUSION The results revealed that the PBPK models were successfully developed for 2.5 mg of warfarin sodium tablets in Chinese individuals. Developing a PBPK model for NTI drugs based on in vitro dissolution data in software is a promising method for BE evaluation, which can provide great help for developing new drugs and the clinical trial research of BE of generic drugs.

Abstract
OBJECTIVES Although generic medicinal products are required to have the same qualitative and quantitative composition of the active substance as their reference originator product, patients and health care professionals express concerns about their interchangeability and safety. Therefore, the present study investigated the antimicrobial activity and pathogen mutation prevention of original and generic cefepime, linezolid and piperacillin/tazobactam against Staphylococcus aureus. METHODS Two generic formulations of cefepime, linezolid and piperacillin/tazobactam were tested against their respective originator products. Susceptibility testing was performed with twenty-one clinical isolates of S. aureus and ATCC-29213 using broth microdilution. Time kill curves (TKC) were performed with ATCC-29213 at drug concentrations above and below the respective minimum inhibitory concentrations (MIC). Mutation prevention concentration was determined for each drug formulation against ATCC-29213. All experiments were performed in triplicate. Mutant colonies from mutation prevention concentration (MPC) experiments were genotypically tested by sequence analysis. RESULTS MIC ratios between contiguous originator and generic drugs were similar for each isolate. No visual differences were observed in TKCs between originator and generic substances. The MPC did not differ between different formulations of the same substance. Although sequence analysis of mutant colonies revealed genomic differences compared with the original ATCC-29213, no differences in mutation frequencies were observed between clinical isolates and ATCC-29213 treated with originator or generic substances. CONCLUSIONS Similar antimicrobial activity and pathogen mutation prevention was observed between contiguous substances. These results support the interchangeability of generic and originator drug formulations with the same active ingredient.

Abstract
The aim of this work was to design pediatric-friendly, dose-flexible orally disintegrating drug delivery systems (printlets) of the antiviral drug tenofovir disoproxil fumarate (TDF) by selective laser sintering (SLS) for potential use in hospitals along with other antiviral drugs. In order to obtain a consistent quality of printlets with desired properties, it is important to understand certain critical quality attributes for their main and interactions effect. The printlets were optimized by Box-Behnken's design of the experiment by varying process variables while keeping the composition constant. The composition contained 16.3% TDF, 72.7% polyvinyl pyrrolidone K16-18, 8% magnesium aluminum silicate, 3% Candurin® NXT Ruby Red, and 0.3% colloidal silicon dioxide. The process variables studied were surface (X1), chamber temperatures (X2), and laser scanning speed (X3). The range of variable levels was 75-85°C for X1, 50-70°C for X2, and 200-240 mm/s for X3, respectively. The responses studied were hardness, disintegration time, dissolution, physiochemical, and pharmacokinetic characterization. X-ray powder diffraction indicated partial or complete conversion of the crystalline drug into amorphous form in the printlets. Comparative pharmacokinetics between Viread® (generic) and printlets in rats were superimposable. Pharmacokinetic parameters showed statistically insignificant differences between the two formulations in terms of Tmax, Cmax, and AUC of (p > 0.05). Printlets were bioequivalent to Viread® as per FDA bioequivalence criteria. Thus, the SLS printing method showed the fabrication of dose-flexible printlets with quality, and in vivo performance equivalent to commercial tablets.

Abstract
PURPOSE A fixed-dose combination (FDC) product combining dapagliflozin and metformin may increase medication adherence in patients with type 2 diabetes mellitus (T2DM) by minimizing pill burden associated with co-administration of individual component (IC) formulations and, consequently, improve cost-efficiency and compliance. This study evaluated the bioequivalence of the dapagliflozin/metformin FDC product versus IC administration in healthy volunteers from a Chinese population and assessed the safety profile of the FDC product. In addition, pharmacokinetic (PK) and safety comparisons of dapagliflozin and metformin across different regions were conducted to evaluate regional differences. METHODS This single-center, open-label, parallel-cohort, randomized, 2-period, crossover study enrolled Chinese adults (aged 18-55 years). Volunteers in cohort 1 received either a single FDC tablet of dapagliflozin/metformin extended release (XR) (5/500 mg) or IC tablets (dapagliflozin [5 mg] and metformin XR [500 mg]). Volunteers in cohort 2 received a higher dosage in a similar manner (dapagliflozin [10 mg] and metformin XR [1000 mg]). Volunteers in each cohort were subsequently crossed over to receive the alternate cohort treatment. Plasma concentrations of dapagliflozin and metformin were determined, and bioequivalence analyses were performed under standard fed conditions. FINDINGS Eighty healthy Chinese volunteers (89.9% male; mean age, 28.7 years) were randomized into cohort 1 (n = 40) and cohort 2 (n = 39; 1 volunteer withdrew before receiving study treatment). The mean plasma concentration-time profiles of the dapagliflozin and metformin FDC and IC formulations for both doses were found to be nearly superimposable. Dapagliflozin and metformin XR FDC were bioequivalent to the IC tablets, with 90% CIs for each pairwise comparison contained within the 80% to 125% bioequivalence limits. Both the FDC and IC formulations were well tolerated, with no serious adverse events/death. PK parameters for dapagliflozin in the Chinese volunteers were slightly to moderately higher than those from studies conducted in Brazil, Russia, and the United States, and the safety profile of the dapagliflozin/metformin FDC product was consistent with that of other studies. The difference in PK parameters among the 4 regions was not clinically meaningful. IMPLICATIONS The bioequivalence of the dapagliflozin/metformin FDC and IC formulations in healthy Chinese adults was established without any new safety concerns. Notably, the observed bioequivalence may be extrapolated to patients with T2DM as the PK parameters of dapagliflozin and metformin in healthy adults are similar to those reported in patients with T2DM.

Abstract
Background Orodispersible film (ODF) formulation offers ease of use, convenience of administration, and other advantages, especially for patients who have difficulty in swallowing or are on liquid restriction compared with conventional oral formulations for the treatment of erectile dysfunction. Objectives These studies compared the bioequivalence of 50 mg sildenafil citrate ODF formulation (test drug) with the marketed 50 mg sildenafil citrate film-coated tablet (FCT) (ViagraⓇ; Pfizer, New York, NY) (reference drug), with and without water in 2 randomized cross-over studies. Methods Two randomized cross-over studies were conducted. The first study explored the bioequivalence of test drug administered with and without water compared with the reference drug with water. The second study investigated the bioequivalence of test drug, without water, compared with the reference drug with water. Forty-two and 80 healthy male volunteers were recruited in the first and second study, respectively. All volunteers fasted for 10 hours pre-dose. A 1-day washout period between doses was observed. Blood samples were collected at both before (up to 120 minutes before dosing) and after dosing (at different intervals up to 14 hours) stages. Statistical analyses on pharmacokinetic parameters were performed. Safety and tolerability for both the formulations were evaluated. Results In the first study, bioequivalence was demonstrated for sildenafil citrate ODF administered with water when compared with the ViagraⓇ FCT. The ratios of adjusted geometric means (90% confidence interval (CI)) were maximum plasma concentration: 1.02 (94.91-108.78) and area under the plasma concentration-time curve: 1.09 (104.49-113.21) for sildenafil citrate ODF administered with water vs ViagraⓇ FCT. These ratios were within the bioequivalence acceptance range of 80% to 125%, indicating that the bioequivalence criteria were met. The pharmacokinetic parameters for the second study also showed bioequivalence for sildenafil citrate ODF (without water) compared with ViagraⓇ FCT. The ratios of adjusted geometric means (90% CI) were maximum plasma concentration: 1.02 (95.47-109.36) and area under the plasma concentration-time curve: 1.06 (103.42-108.40) for sildenafil citrate ODF administered without water vs ViagraⓇ FCT. Adverse events in both the studies occurred at similar rates for the 2 formulations and were mild in intensity. Conclusions These results suggest that the new ODF formulation can be used interchangeably with the marketed FCT formulation. Sildenafil citrate ODF administered with and without water met bioequivalence criteria compared with ViagraⓇ FCT administered with water under fasted conditions in healthy adult male volunteers. The new ODF formulation can be used as a suitable alternative to the conventional oral solid dosage form.

Abstract
Two open-label, randomized, two-period crossover studies were conducted to investigate the pharmacokinetic (PK) properties, safety, and bioequivalence of the test formulation (KD4004), a new fixed-dose combination (FDC) formulation of dapagliflozin and metformin extended release (XR) tablets, relative to the reference formulation (10 mg dapagliflozin/1,000 mg metformin XR FDC tablet) in healthy subjects under fasting (Part A) and fed (Part B) conditions. After giving the dose, serial blood samples were collected for a period of 48 hours. Primary PK parameters (AUC0-t and Cmax) were used to assess bioequivalence between two dapagliflozin/metformin XR (10/1,000 mg) FDC formulations under fed and fasting conditions. Safety and tolerability were also evaluated. Part A and Part B were completed by 32 and 37 subjects, respectively. Bioequivalence of the two FDC formulations of dapagliflozin and metformin XR tablets was established in both the fasted and the fed conditions as the 90% confidence interval of the ratios of adjusted geometric means for AUC0-t and Cmax were contained within the predefined range of 0.800-1.250 bioequivalence criteria. Single-dose administration of dapagliflozin and metformin XR was safe and well tolerated as the two FDC formulations. In conclusion, both FDC formulations of dapagliflozin and metformin XR tablets were bioequivalent in fed and fasted subjects. All treatments were well tolerated.

Abstract
INTRODUCTION This study evaluated the bioequivalence of ezetimibe/rosuvastatin fixed dose combination compared to the concomitant administration of individual formulations (ezetimibe and rosuvastatin) in Chinese healthy subjects under fasting conditions. METHODS This was a phase I, randomized, open-label, two-treatment, two-period, two-sequence, crossover study conducted in healthy Chinese participants under fasting conditions. Cmax, AUC0-t, and AUC0-∞ from test and individual reference formulations were evaluated to assess bioequivalence. The safety assessments included adverse events (AEs)/treatment-emergent adverse events (TEAEs), potential clinically significant abnormalities (PCSAs) in vital signs, 12-lead electrocardiogram (12-ECG), and clinical laboratory parameters. RESULTS Of the 68 subjects enrolled, 67 were treated. Systemic exposure to rosuvastatin based on Cmax, AUC0-t, and AUC0-∞ was similar in both treatments, with respective arithmetic values 12.4 ng/ml, 117 ng·h/mL, and 120 ng·h/mL for test formulation and 12.7 ng/ml, 120 ng·h/mL, and 123 ng·h/mL for reference formulations. Similarly, systemic exposure to unconjugated ezetimibe was 4.14 ng/ml, 89.7 ng·h/mL, and 102 ng·h/mL for the test formulation and 3.80 ng/ml, 89.7 ng·h/mL, and 102 ng·h/mL for reference formulations. Systemic exposure to total ezetimibe was 70.5 ng/ml, 664 ng·h/mL, and 718 ng·h/mL for test formulation and 60.2 ng/ml, 648 ng·h/mL, and 702 ng·h/mL for reference formulations. The point estimates for rosuvastatin unconjugated ezetimibe and total ezetimibe were in the acceptable range of 0.80-1.25. No deaths or serious adverse events were reported. CONCLUSIONS Fixed dose combination of ezetimibe/rosuvastatin (10 mg/10 mg) achieved bioequivalence with reference to commercial tablets. TRIAL REGISTRATION NUMBER CTR20202108.

Abstract
INTRODUCTION The history of levothyroxine has been linked to advances in the treatment of thyroid disease and to date it is the standard therapy for the treatment of hypothyroidism. Bioequivalence studies are the most widely used method to demonstrate interchangeability, although controversy persists regarding the best design for this molecule declared as a narrow therapeutic index product in many countries. This study aimed to evaluate the pharmacokinetic profile of two formulations of levothyroxine to determine bioequivalence between them. METHODS This two-period, randomized, crossover, blind study was conducted in 80 healthy volunteers, of both sexes, using a single levothyroxine dose of 600 μg with a washout period of 42 days. Blood sampling was performed at - 30 min, - 15 min, and 0 h pre-dose and 30 min, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 24, and 48 h post-dose. RESULTS A total of 78 subjects successfully completed both periods. There were no serious adverse events during the study and both formulations were well tolerated. Baseline correction of serum levothyroxine concentrations was performed before statistical analysis. The mean maximum plasma concentration of the test product (Levotiroxina MK®) was 57.49 ng/mL while for the reference product it reached 59.32 ng/mL. Importantly, both test and reference formulations reached maximum concentrations in plasma at about the same time. The areas under the pharmacokinetic curves with the test product showed AUC0-t of 1407.1 ng h/mL and the reference product 1394.3 ng h/mL. The bioequivalence statistical analysis showed that the 90% confidence interval (CI90%) of the ratio of test over reference formulation was within the bioequivalence margins of 90-111%. For Cmax, the test/reference ratio was 96.2% with CI90% of 91.6-100.9%, and for AUC0-t the test/reference ratio was 99.9 with CI90% of 93.3-107.0%. CONCLUSIONS Both formulations have the same pharmacokinetic profile and are bioequivalent in the narrow therapeutic index required by some health authorities.

Abstract
BACKGROUND Voriconazole is a second-generation triazole that is used to prevent and treat invasive fungal infections. The purpose of this study was to evaluate the pharmacokinetic equivalency of a test formulation and reference formulation (Vfend®) of Voriconazole. MATERIALS AND METHODS This was a randomized, open-label, single-dose, two-treatment, two-sequence, two-cycle, crossover phase I trial. The 48 subjects were equally divided into 4 mg/kg and 6 mg/kg groups. Within each group, the subjects were randomized 1:1 to the test or reference formulation.. After a 7-day washout period, crossover formulations were administered. The blood samples were collected at 0.5, 1.0, 1.33,1.42,1.5, 1.75, 2.0, 2.5, 3.0, 4.0, 6.0, 8.0, 12.0, 24.0, 36.0, 48.0 h later in the 4 mg/kg group, while at 0.5, 1.0, 1.5, 1.75, 2.0, 2.08, 2.17, 2.33, 2.5, 3.0, 4.0, 6.0, 8.0, 12.0, 24.0, 36.0, 48.0 h later in the 6 mg/kg group. The plasma concentrations of Voriconazole were determined by Liquid chromatography-tandem mass spectrometry (LC-MS/MS). The safety of the drug was evaluated. RESULTS The 90% confidence intervals (CIs) of the ratio of geometric means (GMRs) of Cmax, AUC0-t, and AUC0-∞ in both 4 mg/kg and 6 mg/kg groups were within the prespecified bioequivalence limits between 80 ~ 125%. In the 4 mg/kg groups, 24 subjects were enrolled and completed the study. The mean Cmax was (2.552 ± 0.448) μg/mL, AUC0-t was (11.875 ± 7.157) h*μg/mL and AUC0-∞ was (12.835 ± 9.813) h*μg/mL after a single dose of 4 mg/kg test formulation. The mean Cmax was (2.615 ± 0.464) μg/mL, AUC0-t was (12.500 ± 7.257) h*μg/mL and AUC0-∞ was (13.416 ± 9.485) h*μg/mL after a single dose of 4 mg/kg reference formulation. In the 6 mg/kg groups, 24 subjects were enrolled and completed the study. The mean Cmax was (3.538 ± 0.691) μg/mL, AUC0-t was (24.976 ± 12.364) h*μg/mL and AUC0-∞ was (26.212 ± 14.057) h*μg/mL after a single dose of 6 mg/kg test formulation. The mean Cmax was (3.504 ± 0.667) μg/mL AUC0-t was (24.990 ± 12.455) h*μg/mL and AUC0-∞ was (26.160 ± 13.996) h*μg/mL after a single dose of 6 mg/kg reference formulation. Serious adverse event (SAE) was not observed. CONCLUSION In both 4 mg/kg group and 6 mg/kg group, equivalent pharmacokinetic characteristics that satisfied the criteria of bioequivalence for both test and reference formulations of Voriconazole.

Abstract
OBJECTIVE The aim of this study was to examine the pharmacokinetics, bioequivalence, and safety of two tablet formulations of capecitabine 500 mg in Chinese patients with breast, colorectal or gastric cancer under fed condition. METHODS A multicentric, randomized, open-label, single-dose, two-period, two-way crossover trial was conducted by randomizing a single oral dose of test (T) or reference (R, Xeloda®) capecitabine (500 mg) to patients of either sex with colon, colorectal or breast cancer under fed condition (high-fat and high-calorie diet). Pharmacokinetic parameters were calculated using non-compartmental methods. Patients were monitored for safety and tolerability throughout the study. RESULTS 74 subjects were randomly enrolled. The T/R geometric mean ratios (GMRs) and 90% confidence intervals (CIs) for Cmax, AUC0-t and AUC0-∞ of capecitabine were 96.60% (85.87-108.67%), 99.07% (95.40-102.89%), 99.17% (95.29-103.21%), respectively. All 90% CIs fell within the bioequivalence acceptance range of 80.00-125.00%. The common adverse events (AEs) included clinically significant laboratory abnormalities and gastrointestinal diseases. There were no serious adverse events (SAEs) or deaths during the study. No subject withdrew from the study due to AEs. CONCLUSION Single oral intake of test and the reference capecitabine tablets were bioequivalent under fed condition and had similar favourable safety profiles in Chinese patients with breast, colorectal or gastric cancer.

Abstract
This work describes the potential applicability of the BCS-based Biowaiver to oral solid dosage forms containing Levamisole hydrochloride, an anthelmintic drug on the WHO List of Essential Medicines. Solubility and permeability data of levamisole hydrochloride were searched in the literature and/or measured experimentally. Levamisole hydrochloride is a highly soluble drug, but there is no clear evidence of high permeability in humans, indicating that it should provisionally be assigned to BCS class III. The biowaiver procedure would thus be applicable for solid oral dosage forms containing levamisole hydrochloride as the only active ingredient. Due to the lack of data in the literature regarding excipient effects on the bioequivalence of products containing levamisole, it is currently recommended that the products comply with the ICH and WHO guidelines: the test formulation should have the same qualitative composition as the comparator, contain very similar quantities of those excipients, and be very rapidly dissolving at pH 1.2, 4.5, and 6.8. However, for certain well-studied excipients, there appears to be opportunity for additional regulatory relief in future versions of the ICH BCS Guidance M9, such as not requiring that the quantities of these common excipients in the test and comparator be the same.

Abstract
PURPOSE The study was aimed at evaluating the bioequivalence and safety of oseltamivir phosphate for suspension, provided by Shenzhen Beimei Pharmaceutical Co. Ltd. and manufactured by Hetero Labs Limited, and the reference product TAMIFLU® in healthy Chinese subjects. METHODS A single-dose, randomized, two-phase, self-crossed model was adopted. Among 80 healthy subjects, 40 subjects in the fasting group and 40 subjects in the fed group. Subjects in the fasting group were randomized into two sequences according to the proportion of 1:1, each given 75 mg/12.5 mL of Oseltamivir Phosphate for Suspension or TAMIFLU®, and cross-administered after 7 days. Postprandial group is the same as fasting group. RESULTS The Tmax of TAMIFLU® and Oseltamivir Phosphate for Suspension in the fasting group were 1.50 h and 1.25 h, which in the fed group were both 1.25 h. Geometrically adjusted mean ratios of the PK parameters of Oseltamivir Phosphate for Suspension along with TAMIFLU® under fasting and postprandial conditions were in the range of 80.00-125.00% at the 90% confidence interval (CI). The 90% CI of Cmax, AUC0-t, AUC0-∞ for fasting group and postprandial group were (92.39,106.50), (94.26,100.67), (94.32,100.89) and (93.61,105.83),(95.64,100.19),(96.06,102.66). Among the subjects on medication, a total of 18 subjects reported 27 adverse events, all of which were treatment-emergent adverse events (TEAEs), six of these TEAEs were rated as grade 2 in severity and the rest were as grade 1. The number of TEAEs in the test product and the reference product were 14,13 respectively. CONCLUSION Two Oseltamivir phosphate for suspensions are safe and bioequivalent.

Abstract
BACKGROUND Dasatinib (Sprycel®) is a tyrosine kinase inhibitor for treating chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia. RESEARCH DESIGN & METHODS We designed a clinical study to demonstrate that the dasatinib tablet (YiNiShu®) (Chia Tai Tianqing Pharmaceutical Group Co., Ltd) and Dasatinib (Bristol Myers Squibb) were bioequivalent under fasting and fed conditions. The whole study was structured into the fasting trial and the postprandial trial. Each period, subjects were given 50 mg dasatinib or its generic. The RSABE (reference scale average bioequivalence) and ABE (average bioequivalence) methods were employed to assess bioequivalence by pharmacokinetics (PK) parameters for a highly variable drug. RESULTS 32 and 24 eligible volunteers were enrolled in the fasting and postprandial trials, respectively. In the fasting trial, the RSABE method was performed, and point estimates of Cmax, AUC0-t, and AUC0-∞ met the bioequivalence criteria. In the postprandial trial, the ABE method was performed, and the 90% CI of the geometric mean ratio (GMR) for PK parameters met the requirements of bioequivalence standards. CONCLUSION The results proved that the PK parameters of the two drugs were similar and bioequivalent, indicating that both drugs had a good safety profile.

Abstract
BACKGROUND Tocilizumab, a recombinant monoclonal immunoglobulin G, targets the interleukin-6 receptor. MSB11456 is a proposed tocilizumab biosimilar. OBJECTIVES To assess pharmacokinetic equivalence of intravenous MSB11456 to US-licensed tocilizumab. RESEARCH DESIGN AND METHODS In this double-blind, parallel-group, single-dose study, 128 healthy adults were randomized to a single one-hour 8 mg/kg IV infusion of either MSB11456 or US-licensed tocilizumab. Blood samples were collected pre-dose and at regular intervals up to day 48 post-dose. The primary endpoint pharmacokinetic parameter was analyzed using analysis of variance (ANOVA) model on the natural logarithm of the endpoint (AUC0-last), with treatment as a fixed effect. Immunogenicity and safety data were summarized descriptively. RESULTS Subjects received either MSB11456 (N = 62) or US-licensed tocilizumab (N = 66). Pharmacokinetic bioequivalence, defined as 90% confidence intervals for the geometric least squares mean ratio entirely contained within the 80.00% to 125.00% equivalence limits, was demonstrated between MSB11456 and US-licensed tocilizumab for the primary and secondary pharmacokinetic endpoints. Anti-drug antibody responses, frequency of neutralizing antibodies against tocilizumab, and safety profiles showed no notable between-treatment differences. Safety was comparable between treatments. CONCLUSIONS Pharmacokinetic similarity of MSB11456 and US-licensed tocilizumab was demonstrated, with comparable immunogenicity and safety profiles, supporting MSB11455 as a biosimilar to US-licensed tocilizumab. The trial is registered at EudraCT, number 2019-003484-22.

Abstract
BACKGROUND Ezetimibe is a new class of antihyperlipidemic agent indicated for the prevention of atherosclerosis disease and for the treatment of hypercholesterolemia. Information on the pharmacokinetic profiles of ezetimibe tablet in healthy Chinese volunteers are lacking, and regulatory requirements necessitate a bioequivalence study of ezetimibe tablet versus Ezetrol® in China. METHODS A single-dose randomized, open-label, two-group, two-period crossover study was conducted in 59 healthy Chinese volunteers under fasting or fed conditions to assess the bioequivalence between two preparations. Eligible participants were randomly divided into fasted and fed groups. Blood samples were collected at specified time intervals, and the plasma concentrations of ezetimibe and ezetimibe glucuronide were determined by a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. PK and bioavailability parameters were estimated via non-compartmental methods. Adverse events were also recorded. RESULTS Fifty-nine healthy volunteers were enrolled in the study. The main pharmacokinetic parameters of total ezetimibe in the plasma of the ezetimibe tablet (10 mg) and the Ezetrol® (10 mg) after a single fasting administration: Cmax were (65.73 ± 47.14), (71.32 ± 51.98) ng·mL- 1; Tmax were 1.75, 1.25 h; T½ were (17.09 ± 13.22), (17.35 ± 12.14) h; AUC0-t were (643.34 ± 400.77), (668.49 ± 439.57) h·ng·mL- 1; AUC0-∞ were (706.36 ± 410.92), (734.23 ± 468.26) h·ng·mL- 1. The main pharmacokinetic parameters of total ezetimibe in plasma of ezetimibe tablet (10 mg) and Ezetrol® (10 mg) after a fed administration: Cmax were (83.38 ± 38.95), (84.74 ± 34.62) ng·mL- 1; Tmax were 2.50, 2.50 h; T½ were (22.56 ± 12.68), (19.80 ± 15.59) h; AUC0-t were (494.21 ± 208.65), (536.69 ± 209.11) h·ng·mL- 1; AUC0-∞ were (573.74 ± 252.74), (604.75 ± 247.13) h·ng·mL- 1. The main pharmacokinetic parameters Cmax, AUC0-t, and AUC0-∞ of the two drugs were analyzed by variance analysis after logarithmic transformation. The total ezetimibe under fasting state with 90% confidence intervals (CIs) were 85.29 ~ 97.19, 90.41% ~ 104.38%, and 90.81 ~ 106.05%; total ezetimibe in fed state were 86.36% ~ 109.17, 84.96% ~ 96.40, and 85.32% ~ 101.0%. The 90% CIs of the ratio of geometric means (GMRs) of Cmax, AUC0-t, and AUC0-∞ of Ezetrol® and ezetimibe tablet both fasting and fed conditions fell within the conventional bioequivalence criteria of 0.80-1.25. Both Cmax and AUC met the predetermined criteria for assuming bioequivalence. No severe adverse events were observed. CONCLUSIONS The test ezetimibe tablet and Ezetrol® were determined to be bioequivalent under both fasting and fed conditions in Chinese people.

Abstract
OBJECTIVE Imnovid® is an immunomodulatory drug with antineoplastic activity. The aim of this study was to evaluate the bioequivalence and safety of the generic drug pomalidomide (Chia Tai Tianqing Pharmaceutical Group Co., Ltd) and its originator product Imnovid® (Celgene Europe Ltd) in the fasting and fed states, respectively. METHODS The research consisted of two parts: one with a dose of 1 mg and the other with a dose of 4 mg. 48 healthy subjects were included in each study and were divided into two groups (fasting group and fed group) at a 1:1 ratio to administrate study drugs orally. The plasma drug concentrations were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS The 90% CI of GMR for main pharmacokinetic (PK) parameters (Cmax, AUC0 - t and AUC0-∞) met the requirements of bioequivalence standards. The incidence and severity of AEs associated with pomalidomide and Imnovid® were similar. CONCLUSION The results proved the PK parameters of pomalidomide and Imnovid® were similar and bioequivalent. Both drugs showed safety profile well.

Abstract
INTRODUCTION Three studies compared the bioequivalence (BE) of new generic tablet formulations of sitagliptin (100 mg; fasting) and the fixed-dose combination (FDC) of sitagliptin/metformin (50/850 mg, 50/1000 mg; both fed) in healthy volunteers with the same tablet strengths of the reference products Januvia and Janumet. METHODS The study design was open-label, single-dose, randomized with two-way crossover periods. Blood sampling was performed for 72/48 h in the sitagliptin/FDC studies, respectively. Primary pharmacokinetic (PK) parameters for sitagliptin and metformin were area under the plasma concentration-time curve from time 0 to last timepoint of measurable concentration (AUC0-t) and maximum plasma concentration (Cmax). Test (T) and reference (R) formulations proved bioequivalent if 90% confidence interval (CI) of geometric least-squares mean ratio for AUC0-t and Cmax were within BE acceptance range of 80.00-125.00%. Safety evaluations included vital signs, clinical laboratory tests, and adverse events (AEs). RESULTS Treated/evaluable volunteers for BE per study were: 30/28 (sitagliptin 100 mg), 26/25 (FDC 50/850 mg), and 26/24 (FDC 50/1000 mg). The 90% CI of the geometric means of T/R ratios for primary PK parameters were within predefined BE limits: CI for AUC0-t and Cmax were 95.83-100.37% and 91.85-109.56% (sitagliptin 100 mg); 100.84-103.69% and 93.44-105.10% (FDC 50/850 mg), and 101.26-105.20% and 98.71-112.89% (FDC 50/1000 mg); respective values for metformin were 94.23-101.89% and 91.66-99.38% (FDC 50/850 mg) and 98.45-104.89% and 96.79-105.62% (FDC 50/1000 mg). All AEs were nonserious, transient, and mostly mild. Safety evaluations did not reveal any relevant difference between T and R formulations. CONCLUSIONS The new generic tablet formulations of sitagliptin 100 mg and the FDCs sitagliptin/metformin 50/850 mg and 50/1000 mg demonstrated bioequivalence to originator reference products. Therefore, the new products are expected to provide efficacy and tolerability similar to those of the reference products in the treatment of patients with type 2 diabetes (T2D).

Abstract
PURPOSE Colorectal cancer (CRC) is the second most common cause of cancer death worldwide. Trifluridine (FTD) remained at higher concentrations longer when administered along with tipiracil (TPI) compared with FTD alone. Lonsurf® is a combination formulation consisting of FTD and TPI. This study aimed to investigate the bioequivalence of FTD/TPI formulations in Chinese metastatic colorectal cancer (mCRC) patients. METHODS In this phase I, randomized, open-label, single-dose, two-sequence, four-cycle crossover study in mCRC patients, the bioequivalence of 60 mg (20 mg tablet, 3 tablets) of the test formulation and the reference formulation (Lonsurf®) was evaluated. Due to its high variability, the method of reference-scaled average bioequivalence (RSABE) was used to investigate the bioequivalence of the test and reference formulations. RESULTS Thirty-two patients were enrolled. 78.1% of the subjects were male, and the mean (standard deviation) age was 53.9 (SD = ± 9.0) years old. The time to reach the maximum plasma concentration (Tmax) was almost 2.0 h post-dose. The geometric least-squares mean ratios (GMRs) (test/reference) of Cmax and AUC0-t for FTD were 95.3% and 102.9%, respectively, with 90% confidence intervals (CIs) for the natural log-transformed ratios of Cmax and AUC0-t of 90.0-100.9% and 99.9-105.9%, while the GMRs of Cmax and AUC0-t for TPI were 95.7% and 100.7%, respectively, with 90% CIs of 90.5-101.2% and 97.0-104.7%. In addition, the GMRs of Cmax and AUC0-t for FTD's major metabolite, trifluorothymine (FTY), were 94.8 (90% CI 90.3-99.5%) and 99.33 (90% CI 96.9-101.9%), respectively. These were in accord with the FDA bioequivalence definition interval of 80-125%. CONCLUSION The test and reference FTD/TPI formulations were bioequivalent in Chinese mCRC patients under fed conditions.

Abstract
It has been revealed that buffer capacity of aspirated human intraluminal fluid is much lower than that of in vitro compendial dissolution media. Since buffer capacity significantly alters the dissolution profile of certain drug products, dissolution testing in highly buffered media dictates poor predictability of in vivo drug performance. To mitigate this inconsistency, low buffer capacity medium was suggested as an in vivo representation (biorelevant dissolution testing). The purpose of this study was to characterize the dissolution profiles of enteric-coated drug products in different buffer capacity media in a flow through cell dissolution apparatus, and to evaluate the in vivo predictability of human bioequivalence study outcomes conducted in the fasted state. It was confirmed that the lower the buffer capacity of dissolution media, the higher the discriminatory power of esomeprazole magnesium hydrate enteric-coated pellets, reflecting human bioequivalence failure. In the meantime, two duloxetine hydrochloride enteric-coated pellets also exhibited distinct dissolution profiles in such a lowly buffered medium despite the fact that these two are bioequivalent in human. Biopharmaceutical and pharmacokinetic characteristics comparison suggested that low intestinal permeability and small systemic elimination rate of duloxetine hinders the clear impact of different dissolution profile on its in vivo performance. These data suggest that dissolution comparison in physiologically-relevant low buffer capacity media is not always indicative of human bioequivalence. Instead, biopharmaceutical and pharmacokinetic aspects must be taken into consideration to make biorelevant dissolution testing biopredictive.

Abstract
Background In the wake of economic challenges, the role of generic medicines has become crucial in meeting the healthcare needs of people. Their use, however, can only be guaranteed if established to be bioequivalent to their corresponding innovator products. Aim In this study, we assess the suitability of a generic brand of cetirizine hydrochloride tablet to be used in place of the innovator brand on the Ghanaian market through bioequivalence assessment. Method An HPLC bioanalytical method was developed and validated for the detection and quantitation of cetirizine in a urine matrix. This was then used to quantify the amount of cetirizine excreted unchanged in urine samples of 12 healthy male volunteers collected over a 24-h period using a two-way crossover design approach. Results Chromatographic separation was successfully achieved with an isocratic elution on a reverse-phase column. The mean retention time for cetirizine was 2.890 ± 0.243 min. The mean cumulative amounts of cetirizine in the reference and test drugs excreted were 5.69 ± 0.98 mg and 5.82 ± 1.96 mg respectively. Other pharmacokinetic parameters including mean relative Areas Under Curve (AUC0-24) of 13.32 and 13.05 μg/mL, and peak Concentration (Cmax) of 3.378 and 3.043 μg/mL at the times at which Cmax was observed (Tmax) being 7.25 and 7.42 min were established respectively for the reference and test drugs. The relative bioavailability was determined to be 102.28, making the locally manufactured brand bioequivalent to the innovator brand. Conclusion The locally manufactured test Cetirizine drug was found to be bioequivalent with the innovator brand and could serve as a suitable alternative to the latter. Additionally, relevant pharmacokinetic parameters for cetirizine has been established using urinary excretion data.

Abstract
UNLABELLED Biosimilar teriparatide (INTG-8) was tested in a healthy population of males and postmenopausal females to assess pharmacokinetic bioequivalence to originator teriparatide comparator products. Primary pharmacokinetic comparison confirmed bioequivalence. Pharmacodynamics, safety, and tolerability were comparable to the originator products. INTG-8 was therefore confirmed to be biosimilar to originator products. INTRODUCTION The purpose of this present study was to demonstrate pharmacokinetic (PK) equivalence of a biosimilar teriparatide (INTG8) to EU- and US-approved teriparatide reference products in healthy men and postmenopausal women. Secondary objectives included comparison of the pharmacodynamics (PD), safety, and tolerability. METHODS One hundred and five subjects randomly (1:1:1) received single subcutaneous 20 μg injection of teriparatide biosimilar, EU- and US-teriparatide on 3 consecutive days in this assessor-blind, three-period, single-dose, crossover study. Maximum serum concentration (Cmax), area under the curve (AUC) from time zero to t (AUC0-t), and AUC from time zero extrapolated to infinity (AUC0-∞) were primary PK parameters, analyzed by non-compartmental methods. The secondary PD endpoints were maximum observed effect (Emax), area under the effect curve (AUE) from time zero to the last measurable concentration (AUE0-t), and time to maximum observed effect (Tmax) for total serum calcium levels. Safety, tolerability, and immunogenicity were also evaluated. This study was registered with ctri.nic.in/ (CTRI/2020/10/028627) on 26 October 2020. RESULTS Baseline demographics were similar across the three-treatment sequence groups. The 90% confidence intervals (CI) for the geometric mean ratios (test:reference) of Cmax, AUC0-t, and AUC0-∞ were within the predefined bioequivalence criterion of 80.00% to 125.00%, which demonstrated PK equivalence of teriparatide biosimilar to EU- and US-teriparatide for all primary endpoints. The PD comparability was demonstrated by similar serum calcium levels. Study treatments were generally well tolerated and showed no meaningful differences in safety or immunogenicity profiles. There were no deaths, or serious AEs were reported during this study. CONCLUSION The study demonstrated PK bioequivalence of teriparatide biosimilar to the EU- and US-teriparatide reference products with comparable PD, safety, and immunogenicity profiles.

Abstract
The purpose of this study was to develop a bicarbonate buffer flow-through cell (FTC) dissolution test. Mesalazine colon targeting tablets of a generic development product (test formulation, TF; Mesalazine 400 mg tablet) and the original product (reference formulation, RF; Asacol® 400 mg tablet) were used as model formulations. A clinical bioequivalence (BE) study was conducted on 48 healthy male subjects under fasting conditions. The oral absorption time profiles were calculated by point-area deconvolution. The compendial paddle and FTC apparatus were used for dissolution tests. Bicarbonate or phosphate-citrate buffer solutions (McIlvaine buffer) were used as the dissolution media. A floating lid was used to maintain the pH value of the bicarbonate buffer solution in the vessel (paddle) or the reservoir (FTC). In the development of bicarbonate FTC method, the pH changes of bicarbonate buffer solution (pH 5.5-7.5; 5-50 mM bicarbonate) were evaluated. For the evaluation of colon targeting tablets, the dissolution profiles of TF and RF were measured at a pH of 7.5. The TF and RF formulations were exposed to 0.01 HCl (pH 2.0) for 2 h before pH 7.5. In the clinical BE study, drug dissolution started 4-8 h after oral administration and continued slowly more than 10 h. Both the area under the curve (AUC) and maximum plasma concentration (Cmax) of TF were approximately twice as high as those of RF. In the development of the bicarbonate FTC method, the pH change of the bicarbonate buffer solution was suppressed by the floating lid within ∆pH < 0.1 over 10 h. In the dissolution test of McIlvaine buffer solutions, TF and RF showed faster disintegration and higher dissolution than those observed in the clinical BE study. When using the paddle apparatus the dissolution profiles of TF and RF in both buffer solutions were not consistent with those of the clinical result. In bicarbonate FTC, the disintegration time, dissolution rate, and dissolution inequivalence between TF and RF were consistent with the results of the clinical BE study. In conclusion, the bicarbonate FTC method was constructed for the first time in this study. This method is simple and practically useful for predicting in vivo performance of colon targeting tablets during drug development.

Abstract
The Drug Regulatory Authority of Pakistan (DRAP) in response to the public outcry on increasing medicines prices in the country issued notifications to direct healthcare professionals to prescribe medicines with their generic names. Like DRAP, many regulators in the low- and middle-income countries (LMICs) are also inspiring from the west to legally enforce generic prescribing in a bid to reduce the out-of-pocket public expenditures. However, there are pitfalls in the LMICs drug regulatory framework, which if left unaddressed can severely jeopardise the foreseen benefits of medicines prescribing by generic names. This article critically appraises the impact of prescribing by generic names regulations in LMICs and highlights the key considerations that are vital to address before legally enforcing generic prescribing. The ethics, regulatory compliance, and good governance are the key to success; better generics for a better tomorrow.

Abstract
BACKGROUND As per the National Medical Products Administration (NMPA) requirements, the quality and efficacy of generic drugs must be consistent with those of the innovator drug. We aimed to evaluate the bioequivalence and safety of generic metformin hydrochloride sustained-release (MH-SR) tablets (Boke®) developed by Beijing Wanhui Double-crane Pharmaceutical Co. Ltd., China and the innovator product metformin hydrochloride extended-release tablets (Glucophage®-XR) manufactured by Bristol-Myers Squibb Company, New York, NY, in healthy Chinese volunteers. MATERIALS AND METHODS We performed a bioequivalence and safety assessment of MH-SR (500 mg/tablet) and Glucophage®-XR (500 mg/tablet) tablets in a randomized, open-label, two-period, two-sequence crossover, single-dose oral study in 48 healthy Chinese adult participants under fasting conditions (Chinese Clinical Trial Registration No. CTR20171306). The washout period was seven days. Bioequivalence (80.00-125.00%) was assessed using adjusted geometric mean ratios (GMRs) and two-sided 90% confidence intervals (CIs) of the area under the curve (AUC) and maximum concentration (Cmax) for each component. RESULTS The 90% CIs of the test/reference preparation for key pharmacokinetic parameters were 97.36-108.30% for AUC0→t, 97.26-108.09% for AUC0→∞ and 96.76-111.37% for Cmax. No severe adverse events (AEs) were observed. However, 38 adverse drug reactions (ADRs) occurred, including metabolic or nutritional conditions (n = 8), infections (n = 2), gastrointestinal conditions (n = 10) and abnormal inspection (n = 18). No significant difference was observed between MH-SR (23 ADRs, 10 participants) and Glucophage®-XR (15 ADRs, 12 participants) (p = .500). Bioequivalence was concluded since the 90% CIs of the main pharmacokinetic parameters were within the equivalence interval (80.00-125.00%). CONCLUSIONS MH-SR (500 mg/tablet) and Glucophage®-XR (500 mg/tablet) were found to be bioequivalent and safe under fasting conditions in healthy Chinese participants. Thus, the market demand for MH-SR tablets (500 mg/tablet) can be met using the generic alternative.KEY MESSAGESGeneric MH-SR tablets (500 mg, Beijing Wanhui Double-crane Pharmaceutical Co. Ltd., Beijing, China) and innovator MH-SR tablets (Glucophage®-XR, 500 mg, Bristol-Myers Squibb Company, New York, NY, USA) were bioequivalent and safe in healthy Chinese volunteers under single-dose administration and fasting conditions.The main goal of this study is to support an increase in the supply of MH-SR tablets in China by proving the efficacy and safety of a generic alternative.Although no sugar was administered in the BE trial of the MH-SR tablets under fasting conditions, no hypoglycaemic event occurred. The method used in this study is expected to serve as a reference for BE studies of different MH-SR formulations.

Abstract
The aim of this study is to investigate pharmacokinetic parameters of test and reference film tablet formulations of a highly variable drug, pinaverium bromide, under fasting conditions and to assess their bioequivalence in accordance with the FDA and EMA criteria. A randomised open-label, single oral dose, three-sequence, three-period, semi-replicated, cross-over trial was conducted with 36 healthy subjects. The intrasubject variability of reference products for Cmax and AUC0-tlast was found to be more than 50%. While bioequivalence was proven according to the FDA reference scaled average bioequivalence approach with only 36 subjects, more than 200 subjects are required to demonstrate bioequivalence in accordance with the EMA bioequivalence guideline. It is believed that the EMA bioequivalence criteria are too stringent for highly variable drugs whose intrasubject variability are more than 30% for both Cmax and AUC0-tlast and that in consequence the EMA ought to revise their bioequivalence guidelines for such drugs in the future.
