[PMID: 38292298 PMCID: PMC10827487 DOI: 10.1016/j.ijpx.2024.100229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Revised: 12/25/2023] [Accepted: 01/05/2024] [Indexed: 02/01/2024] Open
Abstract
The technological process of production of biosimilars determines the degree of biosimilarity to the original biological drug. In particular, the focus is on the similarity of immunogenic responses. The primary endpoint of our retrospective study was to find the differences in SARS-CoV-2 antibody amount between patients treated with original adalimumab and biosimilar adalimumab MSB11022 (Idacio) and the differences in the SARS-CoV-2 antibody amount between patients treated with and without biological treatment. We collected the gender, autoimmune disease type, age, and treatment data of the patients in the outpatient clinic MEDICAL PLUS, s.r.o., Uherske Hradiste. These patients suffer from autoimmune rheumatic diseases. All patients received the mRNA vaccine (Pfizer/BioNTech - BNT162b2), with a 21-day (interquartile range, 21-24) gap between the two vaccinations. Patients receiving adalimumab were able to develop cellular immune responses after the second vaccination dose, as well as the individuals without adalimumab. In the period of 6-23 weeks after the second vaccination dose (D63 - D182), the SARS-CoV-2 antibody levels did not change significantly in the patients receiving the original adalimumab, while in the patients receiving biosimilar adalimumab a significant decrease was revealed. A statistically significant difference in the SARS-CoV-2 antibody amount between the patients without biological treatment (median: 504.3 U/mL) and with biological treatment (Original and Biosimilar - median: 47.2 and 28.2 U/mL, respectively) was confirmed on day 182. According to our observation, the effect of the treatment type on the increase/decrease of antibodies over time is dominant, while the impact of other variables (gender, methotrexate treatment, autoimmune disease type, and age) was confirmed as insignificant or minor.

Abstract
INTRODUCTION COMPACT, a non-interventional study, evaluated the persistence, effectiveness, safety and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA), axial-spondyloarthritis (axSpA) or psoriatic arthritis (PsA) treated with SDZ ETN (etanercept [ETN] biosimilar) in Europe and Canada. METHODS Patients (aged ≥ 18 years) who have been treated with SDZ ETN were categorised on the basis of prior treatment status (groups A-D): patients in clinical remission or with low disease activity under treatment with reference ETN or biosimilar ETN and switched to SDZ ETN; patients who received non-ETN targeted therapies and switched to SDZ ETN; biologic-naïve patients who started SDZ ETN after conventional therapy failure; or disease-modifying anti-rheumatic drug (DMARD)-naïve patients with RA considered suitable for treatment initiation with a biologic and started on treatment with SDZ ETN. The primary endpoint was drug persistence, defined as time from study enrolment until discontinuation of SDZ ETN treatment. RESULTS Of the 1466 patients recruited, 844 (57.6%) had RA, 334 (22.8%) had axSpA and 288 (19.6%) had PsA. Patients had an ongoing SDZ ETN treatment at the time of enrolment for an observed average of 138 days (range 1-841); 22.7% of patients discontinued SDZ ETN through 12 months of study observation. Overall, all the patients receiving SDZ ETN showed good treatment persistence at 12 months with discontinuation rates of 15.2%, 25.7% and 27.8% in groups A, B and C, respectively. Across all patient groups, no major differences were observed in the disease activity and PRO scores between baseline and month 12. Injection-site reactions were low across the treatment groups. CONCLUSION These results support the effectiveness and safety of SDZ ETN treatment in patients with RA, axSpA or PsA in real-life conditions. The treatment persistence rates observed were consistent with previously published reports of patients treated with reference or other biosimilar ETN. No new safety signals were identified.

Abstract
Hematopoietic cell transplantation (HCT) has become a primary treatment for many cancers. Nowadays, the primary source of hematopoietic cells is by leukapheresis collection of these cells from peripheral blood, after a forced egress of hematopoietic cells from marrow into blood circulation, a process known as "mobilization". In this process, mobilizing agents disrupt binding interactions between hematopoietic cells and marrow microenvironment to facilitate collection. As the first essential step of HCT, poor mobilization, i.e. failure to obtain a desired or required number of hematopoietic cell, is one of the major factors affecting engraftment or even precluding transplantation. This review summarizes the available mobilization regimens using granulocyte-colony stimulating factor (G-CSF) and plerixafor, as well as the current understanding of the factors that are associated with poor mobilization. Strategies to mobilize patients or healthy donors who failed previous mobilization are discussed. Multiple novel agents are under investigation and some of them have shown the potential to enhance the mobilization response to G-CSF and/or plerixafor. Further investigation of the risk factors including genetic factors will offer an opportunity to better understand the molecular mechanism of mobilization and help develop new therapeutic strategies for successful mobilizations.

Abstract
Health care costs attributed to biologics have increased exponentially in the recent years, thus biosimilars offer a possible solution to limit costs while maintaining safety and efficacy. Reducing expenditure is vital to health care especially in developing countries where affordability and access to health care is a major challenge. We discuss the opportunities and the challenges of biosimilars in the field of hematopoietic cell transplantation (HCT) in low- and lower-middle income countries. Developing countries can potentially invest in the forecasted costs reduction by utilizing biosimilars. This can be used to decrease the costs of procedures such as HCT, which is a rapidly growing field in many developing regions. The introduction of biosimilars in the developing regions faces many challenges which include, but are not limited to: legal and regulatory issues, lack of research infrastructure, and the presence of educational barriers. Thus, collaborative efforts are needed to ensure an effective and safe introduction of biosimilars into low- and lower-middle income countries.

Abstract
OBJECTIVE To demonstrate comparability between administration of the adalimumab biosimilar, SB5, via prefilled syringe (PFS) and autoinjector (AI) pen based on injection site pain, patient preference, and safety in rheumatoid arthritis (RA) patients. METHODS In this phase 2, open-label study (NCT02565810; EudraCT Number 2014-004887-39), adult RA patients self-administered 40 mg SB5 subcutaneously via PFS at weeks 0 and 2, followed by AI at weeks 4, 6, 8, and 10. Patients rated injection site pain from 0 (no pain) to 10 (severe pain) using a visual numeric scale immediately and 15-30 min post-injection at weeks 0, 2, 4, and 6. Equivalence between PFS and AI was concluded if the 97.5% confidence interval (CI) of the difference in the injection site pain scores at weeks 2 and 6 was contained within the equivalence margin of ±5. Overall impression and preference for PFS and AI were also evaluated. Safety was assessed up to 20 weeks after the first injection. RESULTS Of 49 patients enrolled, 48 completed the study. Mean injection site pain scores were equivalent between PFS and AI immediately (2.3 vs 2.0; 97.5% CI = -0.99-0.30) and 15-30 min post-injection (0.8 vs 0.7; 97.5% CI = -0.47-0.25). The overall impression of both devices was comparable. The overall preference of AI was higher than PFS. Treatment-emergent adverse events (TEAE) were mild-to-moderate. There were no severe or serious TEAEs reported during the study. CONCLUSIONS In RA patients, SB5 showed equivalent injection site pain and comparable safety when administered via PFS and AI.

Abstract
Host directed therapies to boost immunity against infection are gaining considerable impetus following the observation that use of antibiotics has become a continuous source for the emergence of drug resistant strains of pathogens. Receptors expressed by the cells of immune system play a cardinal role in initiating sequence of events necessary to ameliorate many morbid conditions. Although, ligands for the immune receptors are available; but their use is limited due to complex structure, synthesis and cost-effectiveness. Virtual screening (VS) is an integral part of chemoinformatics and computer-aided drug design (CADD) and aims to streamline the process of drug discovery. ImmtorLig_DB is a repertoire of 5000 novel small molecules, screened from ZINC database and ranked using structure based virtual screening (SBVS) against 25 immune receptors which play a pivotal role in defending and initiating the activation of immune system. Consequently, in the current study, small molecules were screened by docking on the essential domains present on the receptors expressed by cells of immune system. The screened molecules exhibited efficacious binding to immune receptors, and indicated a possibility of discovering novel small molecules. Other features of ImmtorLig_DB include information about availability, clustering analysis, and estimation of absorption, distribution, metabolism, and excretion (ADME) properties of the screened small molecules. Structural comparisons indicate that predicted small molecules may be considered novel. Further, this repertoire is available via a searchable graphical user interface (GUI) through http://bioinfo.imtech.res.in/bvs/immtor/ .

Abstract
Purpose The objective of this study was to demonstrate comparable pharmacokinetic (PK), safety, and tolerability parameters of the adalimumab biosimilar SB5 administered via autoinjector (AI) pen or prefilled syringe (PFS). Patients and methods In this phase 1, randomized, open-label, single-dose, parallel-group study, healthy subjects aged 18–55 years were randomized 1:1 to a single dose of 40 mg SB5 delivered subcutaneously via AI or PFS. PK parameters, safety, and tolerability were assessed for 57 days post-dose. The primary endpoint was area under the curve (AUC) of the concentration-time curve from zero to infinity (AUCinf) and from zero to last quantifiable concentration (AUClast) and maximum serum concentration (Cmax). Equivalence was determined using predefined margins of 0.80–1.25 for the 90% CI for the ratio of SB5 AI to SB5 PFS. Results Ninety-five subjects were randomized to each group. Mean serum concentration-time profiles were superimposable between groups. Mean values for AUCinf, AUClast, and Cmax were similar between the SB5 AI and SB5 PFS groups. For the primary endpoints, the 90% CIs for the ratio of geometric least squares means for SB5 AI to SB5 PFS ranged between 0.9503 and 1.2240, which were all within the equivalence margin of 0.80–1.25. Incidence of treatment-emergent adverse events and injection site reactions was similar between groups. Conclusion In healthy subjects receiving a single dose of SB5 via AI or PFS, PK parameters and corresponding 90% CIs were within the predefined margins, showing bioequivalence between the two delivery methods. Safety and tolerability assessments were also similar between groups. ClinicalTrials.gov identifier NCT02326233. EudraCT number 2014-005178-12.

Abstract
Objective The 24‐week equivalent efficacy and comparable safety results of the biosimilar SB5 and reference adalimumab (ADA) from the phase III randomized study in patients with moderate‐to‐severe rheumatoid arthritis (RA) have been reported previously. We undertook this transition study to evaluate patients who switched from ADA to SB5 or who continued to receive SB5 or ADA up to 52 weeks. Methods In this phase III study, patients were initially randomized 1:1 to receive SB5 or ADA (40 mg subcutaneously every other week). At 24 weeks, patients receiving ADA were rerandomized 1:1 to continue with ADA (ADA/ADA group) or to switch to SB5 (ADA/SB5 group) up to week 52; patients receiving SB5 continued with SB5 for 52 weeks (SB5 group). Efficacy, safety, and immunogenicity were evaluated up to 52 weeks. Results The full analysis set population consisted of 542 patients (269 in the SB5 group, 273 in the ADA overall group [patients who were randomized to receive ADA at week 0], 125 in the ADA/SB5 group, and 129 in the ADA/ADA group). The percentages of patients meeting the American College of Rheumatology 20%, 50%, or 70% improvement criteria (achieving an ACR20, ACR50, or ACR70 response) at week 24 were maintained after the transition from ADA to SB5, and these response rates were comparable across treatment groups throughout the study. ACR20 response rates ranged from 73.4% to 78.8% at week 52. Radiographic progression was minimal and comparable across treatment groups. The safety profile and the incidence of antidrug antibodies were comparable across treatment groups after transition. Conclusion SB5 was well tolerated over 1 year in patients with RA, with efficacy, safety, and immunogenicity comparable to those of ADA. Switching from ADA to SB5 had no treatment‐emergent issues such as increased adverse events, increased immunogenicity, or loss of efficacy.

Abstract
OBJECTIVE SB5 is a biosimilar agent for adalimumab (ADA). The aim of this study was to evaluate the efficacy, pharmacokinetics (PK), safety, and immunogenicity of SB5 in comparison with reference ADA in patients with rheumatoid arthritis (RA). METHODS In this phase III, randomized, double-blind, parallel-group study, patients with moderately to severely active RA despite treatment with methotrexate were randomized 1:1 to receive SB5 or reference ADA at a dosage of 40 mg subcutaneously every other week. The primary efficacy end point was the response rate based on the American College of Rheumatology 20% improvement criteria (ACR20) at week 24 in the per-protocol set (completer analysis). Additional end points included efficacy, PK, safety, and immunogenicity assessments. RESULTS Of the 544 patients randomized to receive a study drug, the full analysis set comprised 542 patients (269 in the SB5 group, 273 in the reference ADA group) and the per-protocol set comprised 476 patients (239 receiving SB5, 237 receiving reference ADA). The ACR20 response rate at week 24 in the per-protocol set was equivalent between those receiving SB5 and those receiving reference ADA (72.4% and 72.2%, respectively); the difference in the ACR20 response rate (0.1%, [95% confidence interval -7.83%, 8.13%]) was within the predefined equivalence margin (±15%). Similar results were seen in the full analysis set (missing data being considered a nonresponse). The SB5 and reference ADA treatment groups were comparable across other end points, including the ACR 50% and ACR 70% improvement response rates, Disease Activity Score in 28 joints based on the erythrocyte sedimentation rate, PK data, incidence of treatment-emergent adverse events, and the antidrug antibody response. Subgroup analyses showed that the efficacy and safety of SB5 and reference ADA were comparable regardless of antidrug antibody status. CONCLUSION The ACR20 response rate at week 24 was equivalent between patients treated with the biosimilar agent SB5 and those treated with reference ADA. SB5 and reference ADA were both well tolerated, with comparable safety profiles, in patients with RA.

Abstract
OBJECTIVES To compare the efficacy, safety, immunogenicity and pharmacokinetics (PK) of SB2 to the infliximab reference product (INF) in patients with moderate to severe rheumatoid arthritis (RA) despite methotrexate therapy. METHODS This is a phase III, randomised, double-blind, multinational, multicentre parallel group study. Patients with moderate to severe RA despite methotrexate therapy were randomised in a 1:1 ratio to receive either SB2 or INF of 3 mg/kg. The primary end point was the American College of Rheumatology 20% (ACR20) response at week 30. Inclusion of the 95% CI of the ACR20 response difference within a ±15% margin was required for equivalence. RESULTS 584 subjects were randomised into SB2 (N=291; 290 analysed) or INF (N=293). The ACR20 response at week 30 in the per-protocol set was 64.1% in SB2 versus 66.0% in INF. The adjusted rate difference was -1.88% (95% CI -10.26% to 6.51%), which was within the predefined equivalence margin. Other efficacy outcomes such as ACR50/70, disease activity score measured by 28 joints and European League against Rheumatism response were similar between SB2 and INF. The incidence of treatment-emergent adverse events was comparable (57.6% in SB2 vs 58.0% in INF) as well as the incidence of antidrug antibodies (ADA) to infliximab up to week 30 (55.1% in SB2 vs 49.7% in INF). The PK profile was similar between SB2 and INF. Efficacy, safety and PK by ADA subgroup were comparable between SB2 and INF. CONCLUSIONS SB2 was equivalent to INF in terms of ACR20 response at week 30. SB2 was well tolerated with a comparable safety profile, immunogenicity and PK to INF. TRIAL REGISTRATION NUMBER NCT01936181.

Abstract
Biomedical products are complex molecules, produced by living cells. More accurately, they are molecules that are naturally produced in the human body, like hormones or growth factors, monoclonal antibodies, blood products, immunological medicinal products, sera and vaccines, allergens, and advanced technology products such as gene and cell therapy products. Copies of these drugs, known as biosimilars, are comparable but not identical and are not generic version of innovator biological products. Specific regulatory requirements and abbreviated registration process apply in the case of biosimilars, in order to demonstrate efficacy and safety profile and to prove that product is similar to the original biomedical product. Like all medicines, biological medicines work by interacting with the body to produce a therapeutic outcome, but the mechanisms by which they do this may vary from product to product and through indications. Therefore the role of the physicians in treatment of patients with these complex medicinal products is particularly important. Regulatory issues, manufacturing, safety, physicians have part in develop use of biosimilars as much as generic drugs. Even though, the most important factor for market of biosimilar are commercial factor, still, real clinical dilemma of use are present, so it is necessary to have clear regulatory framework and postmarketing data on the use of biosimilars.
