Abstract
The t(11;14) translocation is among the most prevalent cytogenetic abnormalities in multiple myeloma (MM), distinguished by its unique features and biology that have been thoroughly explored for decades. What further sets this MM subtype apart is its oscillating prognostic significance, from initially being considered a favorable alteration to intermediate risk and potential future reclassification as favorable risk. Despite not being inherently a high-risk alteration indicative of an aggressive phenotype, it appears that t(11;14)-MM is less responsive to novel agents like proteasome inhibitors and immunomodulatory drugs which have otherwise transformed the disease's treatment landscape, perhaps partially explained by its reduced propensity for immunoglobulin production and oligosecretory nature. However, its distinct reliance on Bcl-2 has heightened its sensitivity to venetoclax. Further subclassification based on morphological and genomic characteristics could enhance our prediction models of treatment responses and enable more tailored therapeutic strategies for patients. This review aims to encapsulate the existing research evidence in this area.

Abstract
In this study, a new electropolymerized molecularly imprinted polymer (MIP) film was synthesized on a glassy carbon electrode (GCE) by a photopolymerization (PP) method using acrylamide (AA) as a functional monomer and venetoclax (VEN) as a template molecule. Optimization steps of the MIP film were performed using ferrocyanide/ferricyanide [Fe(CN)6]3-/4- as a redox probe. Removal and rebinding of the template molecule were investigated by differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS). The analytical performance of PP-AA@MIP-GCE was evaluated by comparing the DPV response of MIP with that of nonimprinted polymer (NIP). The limit of detection (LOD) and limit of quantification (LOQ) for DPV determination of VEN on PP-AA@MIP-GCE were 0.016 and 0.055 pM, respectively, and the linearity range was found to be between 0.1 and 1.0 pM. The applicability and legitimacy of the constructed sensor were confirmed through its utilization on synthetic human serum. The selectivity of the sensor was demonstrated using molecules with structures similar to that of VEN and/or drug substances such as ibrutinib and azacitidine, which could potentially be used in combination with VEN. The developed PP-AA@MIP-GCE sensor exhibited high sensitivity and selectivity for VEN and is the first reported method for DPV determination of VEN.

Clin Ther 2024:S0149-2918(24)00080-8. [PMID: 38782609 DOI: 10.1016/j.clinthera.2024.03.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/29/2024] [Accepted: 03/30/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE Venetoclax is a potent, orally bioavailable BCL-2 inhibitor used in the treatment of some hematological malignancies. Crushing tablets may be necessary to help with the administration of venetoclax to patients with swallowing difficulties or patients requiring nasogastric tube feeding. The study was conducted to assess the bioavailability of crushed and finely ground venetoclax tablets relative to whole tablets. METHODS An open-label, randomized, 3-way, crossover study in 15 healthy adult females was conducted. Venetoclax tablets were administered orally in a crushed, ground or intact form on Day 1 of each period with water following a high-fat breakfast. Pharmacokinetic samples were collected up to 72 hours postdosing. FINDINGS The crushed and ground tablets met the bioequivalence criteria (0.80-1.25) relative to the intact tablets with respect to area under the concentration-time curve to time of the last measurable concentration (AUCt) and to infinite time (AUCinf) but exhibited a slightly lower maximum plasma concentration (Cmax). This was not considered clinically significant as only venetoclax overall exposure (AUC) has been shown to correlate with clinical efficacy. There was no change in the physical appearance and the evaluated physicochemical properties of crushed and ground venetoclax tablets after 72 hours of storage at 25°C/60% relative humidity. IMPLICATIONS Crushing or grinding venetoclax tablets before administration could be considered as a viable alternative method of administration for patients who have difficulty swallowing whole venetoclax tablets or patients requiring nasogastric tube feeding. CLINICALTRIALS GOV IDENTIFIERS NCT05909553, registered June 12, 2023.

Abstract
Venetoclax, a highly potent BCL-2 inhibitor, is indicated for treatment of some hematologic malignancies as monotherapy, and/or in combination with other agents. Venetoclax pharmacokinetics has been extensively characterized in patients and healthy participants. After oral dosing, the median time to reach maximum plasma concentration ranged from 5 to 8 h and harmonic mean half-life ranged from 14 to 18 h. Food increases venetoclax bioavailability by 3-5-fold and venetoclax should be administered with food to ensure adequate and consistent bioavailability. Venetoclax is eliminated via cytochrome P450 (CYP)3A metabolism, and a negligible amount of unchanged drug is excreted in urine. Strong CYP3A/P-glycoprotein inhibitors increased venetoclax exposures (AUC) by 1.44- to 6.90-fold while a significant decrease (71%) has been observed when dosed with strong CYP3 inducers. Venetoclax does not inhibit or induce CYP enzymes or transporters. Venetoclax pharmacokinetics is not appreciably altered by age, weight, sex, but the exposure is up to twofold higher in participants from Asian countries. Mild-to-severe renal impairment or end-stage renal disease do not alter venetoclax exposures, and venetoclax is not cleared by dialysis. Although mild-to-moderate hepatic impairment does not affect venetoclax exposures, twofold higher exposure was observed in subjects with severe hepatic impairment. Venetoclax exposure is comparable across patients with different hematologic malignancies and healthy participants. Overall, venetoclax exposure is only affected by food and CYP3A modulators and is only higher in Asian subjects and subjects with severe hepatic impairment. Venetoclax exposure-response relationships are malignancy-dependent and can be different between monotherapy and combination therapy.

Abstract
A simple, highly sensitive and specific method based on high-performance liquid chromatography (HPLC) with ultraviolet detection was developed for the measurement of venetoclax concentrations in plasma samples. The chromatographic method employed a mobile phase of acetonitrile: 0.5% KH2PO4 (pH 3.5) (80/20, v/v) on a CAPCELL PAK C18 UG120 column at a flow rate of 0.5 mL/min. The quantitative method was validated based on standards described in "Bioanalytical Method Validation: Guidance for Industry" published by the US Food and Drug Administration. The separation of venetoclax and the internal standard R051012 was satisfactory, and the chromatograms were free of interfering peaks from the biological matrix. The intra- and inter-day coefficients of variation for venetoclax assays were <12.9%, whereas intra- and inter-day accuracies were within 13.6%. Only 100 μL of human plasma was required to detect a lower limit of quantification of 10 ng/mL for venetoclax. The recoveries of venetoclax extracted with an Oasis HLB cartridge were between 81 and 85%. The developed HPLC method was successfully applied to the determination of venetoclax concentrations in plasma of acute myeloid leukemia patients taking venetoclax. The degree of drug interactions between venetoclax and CYP3A4 inhibitors can be determined by this HPLC assay.

Abstract
Venetoclax, an orally bioavailable BCL-2 inhibitor, has been regarded as a breakthrough for the treatment of leukemia but has a wide interindividual variability and drug-drug interaction in pharmacokinetics. In this study, a simple and sensitive ultra-high performance liquid chromatography-tandem with mass spectrometry method was established and fully validated to quantify venetoclax and voriconazole simultaneously in human plasma. After protein precipitation, the analytes were separated on a Hypersil GOLD C18 column (3 µm, 2.1 × 50 mm) by gradient elution. The mass detection was operated under multiple reaction monitoring mode at m/z 868.5 →636.2 for venetoclax, 350.0 → 127.0 for voriconazole and 353.0 → 127.0 for voriconazole-D3(Internal Standard). The calibration ranges were 0.1-10 μg/mL for venetoclax and 0.05-10 μg/mL for voriconazole with correlation coefficients (r2)>0.998. The validated method was successfully applied to the pharmacokinetic study in acute myeloid leukemia patients receiving venetoclax with or without voriconazole. The results suggested that co-treatment with 200 mg q12h voriconazole, the peak concentration of venetoclax (100 mg qd) could be raised to the same level as the 400 mg qd group. However, the trough concentration of venetoclax (100 mg qd) was much higher than that of the 400 mg qd group. Therapeutic drug monitoring might give some guidance for the adjustment of dosing regimens to guarantee the drug efficacy and safety of patients to some extent.

Therapeutic Monitoring of Orally Administered, Small-Molecule Anticancer Medications with Tumor-Specific Cellular Protein Targets in Peripheral Fluid Spaces-A Review. Pharmaceutics 2023; 15:pharmaceutics15010239. [PMID: 36678867 PMCID: PMC9864625 DOI: 10.3390/pharmaceutics15010239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 12/29/2022] [Accepted: 12/30/2022] [Indexed: 01/13/2023] Open
Abstract
Orally administered, small-molecule anticancer drugs with tumor-specific cellular protein targets (OACD) have revolutionized oncological pharmacotherapy. Nevertheless, the differences in exposure to these drugs in the systemic circulation and extravascular fluid compartments have led to several cases of therapeutic failure, in addition to posing unknown risks of toxicity. The therapeutic drug monitoring (TDM) of OACDs in therapeutically relevant peripheral fluid compartments is therefore essential. In this work, the available knowledge regarding exposure to OACD concentrations in these fluid spaces is summarized. A review of the literature was conducted by searching Embase, PubMed, and Web of Science for clinical research articles and case reports published between 10 May 2001 and 31 August 2022. Results show that, to date, penetration into cerebrospinal fluid has been studied especially intensively, in addition to breast milk, leukocytes, peripheral blood mononuclear cells, peritoneal fluid, pleural fluid, saliva and semen. The typical clinical indications of peripheral fluid TDM of OACDs were (1) primary malignancy, (2) secondary malignancy, (3) mental disorder, and (4) the assessment of toxicity. Liquid chromatography-tandem mass spectrometry was most commonly applied for analysis. The TDM of OACDs in therapeutically relevant peripheral fluid spaces is often indispensable for efficient and safe treatments.

Abstract
BACKGROUND AND OBJECTIVE Venetoclax is an approved BCL-2 inhibitor, currently under evaluation in different hematological malignancies in adult and pediatric populations. Venetoclax is available as 10, 50, and 100 mg tablets. To provide an alternative to patients who find taking the commonly prescribed 100 mg tablet a challenge, the interchangeability of lower-strength tablets with the 100 mg tablet was investigated. Additionally, newly developed oral suspension powder formulations to facilitate dosing in pediatrics were evaluated. METHODS Pharmacokinetic data from 80 healthy female participants from three phase I studies were utilized to evaluate the bioavailability of (1) 10 and 50 mg tablets relative to a 100 mg tablet; (2) 0.72 and 7.2% (drug to total weight) oral powder formulations relative to the 100 mg tablet; and (3) oral powder formulations administered using different vehicles (apple juice, apple sauce, and yogurt) relative to water under fed conditions. RESULTS Bioavailability assessments at a 100 mg dose of venetoclax demonstrated bioequivalence across the 10, 50, and 100 mg tablet strengths. Oral powder formulations met the bioequivalence criteria (0.80-1.25) with respect to area under the concentration-time curve to time of the last measurable concentration (AUCt) and to infinite time (AUC∞) but exhibited a slightly lower maximum plasma concentration (Cmax). Exposure-response analyses were utilized to demonstrate that the lower Cmax observed with the powder formulations is not clinically meaningful. The delivery vehicles tested did not affect the bioavailability of venetoclax oral powder formulations. CONCLUSIONS The smaller-sized tablets (10 and 50 mg) and the newly developed oral powder formulations of venetoclax can be used interchangeably with the 100 mg tablets to improve the patients' experience, while maintaining adequate exposure.

Pharmacokinetics and Exposure-Response Analysis of Venetoclax + Obinutuzumab in Chronic Lymphocytic Leukemia: Phase 1b Study and Phase 3 CLL14 Trial. Adv Ther 2022; 39:3635-3653. [PMID: 35708885 PMCID: PMC9309146 DOI: 10.1007/s12325-022-02170-w] [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: 02/03/2022] [Accepted: 04/21/2022] [Indexed: 11/24/2022]
Abstract
INTRODUCTION This study aims to investigate pharmacokinetics (PK) and exposure-response parameters of the 400 mg once-daily venetoclax dose regimen in combination with obinutuzumab, which was approved for the first-line (1L) treatment of chronic lymphocytic leukemia (CLL) based on data from the phase 3 CLL14 study and the phase 1b dose-finding GP28331 study. METHODS Parameter estimates and uncertainty, which were estimated by a previously developed population PK (popPK) model, were used as informative priors for this analysis. They were re-estimated, and then used to evaluate additional covariate effects, describe venetoclax PK when administered with obinutuzumab, and provide empirical Bayes estimates of PK parameters and exposure. Exposure-progression-free survival (PFS) and exposure-safety relationships were assessed using data from CLL14, with steady-state nominal venetoclax exposure (CmeanSS,nominal) as the predictor variable. Exposure-safety analyses were conducted using logistic regression for selected treatment-emergent grade ≥ 3 adverse events (AEs) and serious AEs (SAEs). Dose intensities were summarized by tertiles of CmeanSS,nominal. RESULTS PK data from 274 patients (CLL14, n = 194; GP28331, n = 80) were included. The final model provided good fit of the observed data. Obinutuzumab co-administration, history of prior treatments, and disease severity at baseline had no appreciable influence on venetoclax steady-state exposure. No significant correlations were observed between venetoclax exposure and PFS, or between venetoclax exposure and the probability of treatment-emergent grade ≥ 3 neutropenia, grade ≥ 3 thrombocytopenia, grade ≥ 3 infections, and SAEs. Median dose intensities for venetoclax and obinutuzumab remained similar across venetoclax exposure tertiles. CONCLUSION PopPK and exposure-efficacy, exposure-safety, and exposure-tolerability analyses support the 400 mg once-daily venetoclax dose plus obinutuzumab for 1L treatment in patients with CLL.

Abstract
The oral BCL-2 inhibitor venetoclax has demonstrated promising efficacy in patients with t(11;14) plasma cell disorders, both as a single-agent and in combination. However, there was an increased mortality signal in the randomized BELLINI trial that was primarily driven by non-t(11;14) patients. Based on current evidence, venetoclax is included as an option for relapsed/refractory t(11;14) plasma cell dyscrasias in NCCN guidelines and is being widely used in clinical practice. In this review, we aim to critically appraise the current literature and perform case-based illustration of our approach to management of t(11;14) plasma cell disorders with venetoclax.

Abstract
Relapse at the central nervous system (CNS) in acute myeloid leukemia (AML) carries a dismal prognosis. Treatment options are limited to intrathecal therapy, high-dose cytarabine, high-dose methotrexate, and radiotherapy. Novel strategies are needed. Venetoclax has recently been approved by the FDA, in combination with hypomethylating agents or low-dose cytarabine, for elderly adults or patients ineligible for intensive chemotherapy affected by AML. However, little is known on its efficacy in patients with leptomeningeal involvement. Here, we present a case of a 52-year-old patient affected by AML relapsed at CNS after allogeneic bone marrow transplantation who was treated with venetoclax. We evaluated the concentration of the drug in cerebrospinal fluid (CSF) by HPLC MS/MS method on three different occasions to verify the penetration of the drug through the brain-blood barrier and we observed that the concentration in CSF was similar to the IC50 established in vitro.

A microdosing framework for absolute bioavailability assessment of poorly soluble drugs: A case study on cold-labeled venetoclax, from chemistry to the clinic. Clin Transl Sci 2021; 15:244-254. [PMID: 34416076 PMCID: PMC8742638 DOI: 10.1111/cts.13144] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/10/2021] [Accepted: 07/07/2021] [Indexed: 11/26/2022] Open
Abstract
This work presents an end‐to‐end approach for assessing the absolute bioavailability of highly hydrophobic, poorly water‐soluble compounds that exhibit high nonspecific binding using venetoclax as a model drug. The approach utilizes a stable labeled i.v. microdose and requires fewer resources compared with traditional approaches that use radioactive 14C‐labeled compounds. The stable labeled venetoclax and internal standard were synthesized, then an i.v. formulation was developed. In the clinical study, female subjects received a single oral dose of venetoclax 100 mg followed by a 100‐µg i.v. dose of cold‐labeled 13C‐venetoclax at the oral time of maximum concentration (Tmax). The i.v. microdose was prepared as an extemporaneous, sterile compounded solution on the dosing day by pharmacists at the clinical site. Several measures were taken to ensure the sterility and safety of the i.v. preparation. A sensitive liquid chromatography‐tandem mass spectrometry method was developed to allow the detection of plasma levels from the i.v. microdose. Plasma samples were collected through 72 h, and pharmacokinetic parameters were estimated using noncompartmental methods. Postdosing sample analysis demonstrated the consistency of the preparations and allowed the precise calculation of the pharmacokinetic parameters based on the actual injected dose. The absolute bioavailability of venetoclax was estimated at 5.4% under fasting conditions. Venetoclax extraction ratio was estimated to be 0.06 suggesting that the fraction transferred from the enterocytes into the liver is limiting venetoclax bioavailability. The proposed framework can be applied to other highly hydrophobic, poorly water‐soluble compounds that exhibit high nonspecific binding to support the understanding of their absorption and disposition mechanisms and guide formulation development.

Abstract
Venetoclax (VX) used in the treatment of chronic lymphocytic leukemia possesses low oral bioavailability (5.4%) and undergoes first-pass metabolism. Development of a formulation to overcome its bioavailability problem can be done by using nanocrystals which has many scientific applications. Nanocrystals of VX were formulated using amalgamation of precipitation and high-pressure homogenization method, in which polyvinyl alcohol (PVA) was selected as stabilizer. Process parameters like concentration of stabilizer, homogenization pressure, number of homogenization cycle, and concentration of lyoprotectant were optimized to obtain the desired particle size for the preparation of nanocrystal formulation. HPLC methods were developed and validated in-house for determination of in vitro dissolution data and in vivo bioavailability data. Physicochemical characterization was done to determine the particle size (zeta sizer), crystalline nature (DSC and XRPD), solubility (shaker bath), and dissolution (USP type 2 apparatus). Lyophilized VX nanocrystals of size less than 350 nm showed substantial increase in saturation solubility (~20 folds) and dissolution in comparison with free VX. In vitro release study revealed that 100% dissolution was achieved in 120 min as compared to VX free base which is having less than 43.5% dissolution in 120 min. Formulations of VX remain stable for 6 months under accelerated stability conditions. In vivo pharmacokinetic data in male Sprague-Dawley rats showed (~2.02 folds) significant increase in oral bioavailability of VX formulation as compared to free drug because of rapid dissolution and absorption which makes the nanocrystal formulation a better approach for oral administration of poorly soluble drugs.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) is an aggressive malignancy with poor prognosis and high rates of relapse, especially in elderly patients who are ineligible to receive intensive chemotherapy. Venetoclax, an oral BCL-2 inhibitor, is approved by the Food and Drug Administration in combination with hypomethylating agents or low-dose cytarabine in newly-diagnosed AML patients who are ineligible to receive intensive chemotherapy. Confirmatory phase III VIALE-A and VIALE-C trials showed a composite complete remission rate of 66.4% and 48%, respectively. Thus, further validating venetoclax as an attractive therapeutic option in the AML treatment landscape. AREAS COVERED A review of venetoclax in AML, focusing on preclinical and clinical data, toxicity profile, and mechanisms of resistance; and its strengths and weaknesses in regards to its current and future role in AML treatment is discussed. To find relevant studies, authors searched PubMed/Medline and ClinicalTrials.gov. EXPERT OPINION The introduction of venetoclax-based combination therapies has greatly expanded the therapeutic options for elderly and chemotherapy-ineligible AML patients. Additional studies with extended follow-up are necessary to address remaining open questions such as (I) durability of responses, (II) head-to-head comparisons with intensive chemotherapy in selected patients (e.g. TP53 mutations), and (III) novel triplet combinations using an HMA-venetoclax backbone.

Abstract
DAV132 is a novel colon-targeted adsorbent that prevents the deleterious impact of antibiotics on gut microbiota without modifying their systemic availability. A randomized, Latin-square crossover, open-label trial with 2 substudies in 18 and 24 healthy volunteers evaluated the pharmacokinetic (PK) bioequivalence of warfarin, a drug with a narrow therapeutic index (NTI), and clonazepam, both widely used for the treatment of chronic conditions, with or without coadministration of DAV132 7.5 g. PK parameters observed with single doses of 5 mg warfarin and 1 mg clonazepam when administered alone did not differ with the PK parameters when administered concomitantly with or 1 hour before DAV132. Geometric mean ratios (GMRs) for S-warfarin, R-warfarin, and clonazepam Cmax were 102.0, 102.8, and 91.9, respectively, after concomitant administration and 106.5, 107.5, and 95.0, respectively, when administered 1 hour before DAV132. After concomitant administration, GMRs for S-warfarin, R-warfarin, and clonazepam AUClast were 100.5, 100.2, and 94.9, respectively, and 101.9, 101.8, and 101.3, respectively, when administered 1 hour before DAV132. All GMR 90% confidence intervals fell within the prespecified 80% to 125% limit for bioequivalence, indicating a lack of drug-drug interaction. In conclusion, DAV132 did not affect the systemic exposure of 2 NTI drugs absorbed in the proximal intestine.

Abstract
BACKGROUND Venetoclax is a selective B-cell lymphoma-2 (BCL-2) inhibitor approved for use as monotherapy or with rituximab in patients with chronic lymphocytic leukemia (CLL). The objectives of the current analysis of observed data from adult patients randomized to venetoclax-rituximab in the phase III MURANO study were to characterize venetoclax pharmacokinetics (PKs) using a Bayesian approach, evaluate whether a previously developed population PK model for venetoclax can describe the PKs of venetoclax when administered with rituximab, and to determine post hoc estimates of PK parameters for the exposure-response analysis. METHODS Parameter estimates and uncertainty estimated by a population PK model were used as priors. Additional covariate effects (CLL risk status, geographic region, and 17p deletion [del(17p)] status) were added to the model. The updated model was used to describe venetoclax PKs after repeated dosing in combination with rituximab, and to determine post hoc estimates of PK parameters for exposure-response analysis. RESULTS The PK analysis included 600 quantifiable venetoclax PK samples from 182 patients in the MURANO study. Model evaluation using standard diagnostic plots, visual predictive checks, and normalized prediction distribution error plots indicated no model deficiencies. There was no significant relationship between venetoclax apparent clearance (CL/F) and bodyweight, age, sex, mild and moderate hepatic and renal impairment, or coadministration of weak cytochrome P450 3A inhibitors. The chromosomal abnormality del(17p) and CLL risk status had no apparent effect on the PKs of venetoclax. A minimal increase in venetoclax CL/F (approximately 7%) was observed after coadministration with rituximab. CL/F was 30% lower in patients from Central and Eastern Europe (n = 60) or Asia (n = 4) compared with other regions (95% confidence interval [CI] 21-39%). Apparent central volume of distribution was 30% lower (95% CI 22-38%) in females (n = 56) compared with males (n = 126). No clinically significant impact of region or sex was observed on key safety and efficacy outcomes. CONCLUSIONS The Bayesian model successfully characterized venetoclax PKs over time and confirmed key covariates affecting PKs in the MURANO study. The model was deemed appropriate for further use in simulations and for generating individual patient PK parameters for subsequent exposure-response evaluation.

Abstract
In this study, high-performance liquid chromatography with fluorescence detection (HPLC-FLD) has been used for the first time, for direct determination of warfarin and its major metabolite, 7-hydroxywarfarin, in rat plasma. The simple and sensitive method was developed using Fortis® reversed-phase diphenyl column (150 × 4.6 mm, 3 μm) and a mobile phase composed of phosphate buffer (25 mmol L-1)/methanol/acetonitrile (70:20:10, V/V/V), adjusted to pH 7.4, at a flow rate of 0.8 mL min-1. The diphenyl chemistry of the stationary phase provided a unique selectivity for separating the structurally related aromatic analytes, warfarin and 7-hydroxywarfarin, allowing their successful quantification in the complex plasma matrix. The method was linear over the range 0.01-25 μg mL-1, for warfarin and 7-hydroxywarfarin, and was found to be accurate, precise and selective in accordance with US FDA guidance for bioanalytical method validation. The method was sensitive enough to quantify 0.01 μg mL-1 of warfarin and 7-hydroxywarfarin (LLOQ) using only 100 μL of plasma. The applicability of this method was demonstrated by analyzing samples obtained from rats after oral administration of a single warfarin dose, and studying warfarin and 7-hydroxywarfarin pharmacokinetics.

Abstract
INTRODUCTION Venetoclax is a selective B cell lymphoma-2 inhibitor. It is approved for treatment of chronic lymphocytic leukemia and is being investigated for other hematological malignancies. Venetoclax is predominantly eliminated by the liver; therefore, there is a need to investigate the effect of hepatic insufficiency on venetoclax pharmacokinetics. METHODS A phase I study was carried out in 24 women with normal hepatic function or mild, moderate, or severe hepatic impairment (based on Child-Pugh scores), who received a single 50 mg dose of venetoclax with a low-fat meal. Blood samples were collected up to 120 h after venetoclax administration. Pharmacokinetic parameters were estimated using non-compartmental methods. RESULTS Venetoclax maximum observed plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC) in subjects with mild or moderate hepatic impairment were similar to subjects with normal hepatic function. Mean venetoclax AUC in subjects with severe hepatic impairment was 2.3- to 2.7-fold higher than in subjects with normal hepatic function. The half-life of venetoclax in subjects with severe hepatic impairment was approximately two-fold longer than in subjects with normal hepatic function and subjects with mild or moderate hepatic impairment. Unbound fractions of venetoclax in subjects with mild, moderate, and severe hepatic impairment were similar to the subjects with normal hepatic function. No significant adverse safety events were reported. CONCLUSIONS No venetoclax dosage adjustment is required in subjects with mild or moderate hepatic impairment. In subjects with severe hepatic impairment, a 50% dose reduction of venetoclax is recommended to account for higher exposures and the longer half-life.

Abstract
Several small molecule inhibitors (SMIs) have been recently approved for AML patients. These targeted therapies could be more tolerable than classical antineoplastics, but potential drug-drug interactions (DDI) are relatively frequent. Underestimation or lack of appropriate awareness and management of DDIs with SMIs can jeopardize therapeutic success in AML patients, which often require multiple concomitant medications in the context of prior comorbidities or for the prevention and treatment of infectious and other complications. In this systematic review, we analyze DDIs of glasdegib, venetoclax, midostaurin, quizartinib, gilteritinib, enasidenib, and ivosidenib. CYP3A4 is the main enzyme responsible for SMIs metabolism, and strong CYP3A4 inhibitors, such azoles, could increase drug exposure and toxicity; therefore dose adjustments (venetoclax, quizartinib, and ivosidenib) or alternative therapies or close monitoring (glasdegib, midostaurin, and gilteritinib) are recommended. Besides, coadministration of strong CYP3A4 inducers with SMIs should be avoided due to potential decrease of efficacy. Regarding tolerability, QTc prolongation is frequently observed for most of approved SMIs, and drugs with a potential to prolong the QTc interval and CYP3A4 inhibitors should be avoided and replaced by alternative treatments. In this study, we critically assess the DDIs of SMIs, and we summarize best management options for these new drugs and concomitant medications.

Abstract
Venetoclax (Venclyxto®; Venclexta®) is a first-in-class, oral, selective B cell lymphoma-2 (BCL-2) inhibitor. The drug is approved in numerous countries, including those of the EU and in the USA, for the treatment of adults with relapsed or refractory (RR) chronic lymphocytic leukemia (CLL); the specific indication(s) for venetoclax may vary between individual countries. Venetoclax monotherapy or combination therapy with rituximab was an effective treatment, provided durable responses, and had a manageable safety profile in pivotal clinical trials in adults with RR CLL, including in patients with adverse prognostic factors. In combination with 6 cycles of rituximab, venetoclax (fixed 24 months' treatment) was more effective than bendamustine plus rituximab (6 cycles) in prolonging progression-free survival (PFS) and inducing undetectable minimal residual disease (uMRD) in peripheral blood (PB) and bone marrow (BM), with these benefits sustained during 36 months' follow-up. Hence, with its novel mechanism of action and convenient oral once-daily regimen, venetoclax monotherapy or fixed 24-month combination therapy with rituximab represents an important option for treating RR CLL, including in patients with del(17p) or TP53 mutation and those failing a B cell receptor (BCR) inhibitor and/or chemotherapy.

Abstract
BACKGROUND Outcomes for children with relapsed or refractory acute myeloid leukaemia remain poor. The BCL-2 inhibitor, venetoclax, has shown promising activity in combination with hypomethylating agents and low-dose cytarabine in older adults for whom chemotherapy is not suitable with newly diagnosed acute myeloid leukaemia. We aimed to determine the safety and explore the activity of venetoclax in combination with standard and high-dose chemotherapy in paediatric patients with relapsed or refractory acute myeloid leukaemia. METHODS We did a phase 1, dose-escalation study at three research hospitals in the USA. Eligible patients were aged 2-22 years with relapsed or refractory acute myeloid leukaemia or acute leukaemia of ambiguous lineage with adequate organ function and performance status. During dose escalation, participants received venetoclax orally once per day in continuous 28-day cycles at either 240 mg/m2 or 360 mg/m2, in combination with cytarabine received intravenously every 12 h at either 100 mg/m2 for 20 doses or 1000 mg/m2 for eight doses, with or without intravenous idarubicin (12 mg/m2) as a single dose, using a rolling-6 accrual strategy. The primary endpoint was the recommended phase 2 dose of venetoclax plus chemotherapy and the secondary endpoint was the proportion of patients treated at the recommended phase 2 dose who achieved complete remission or complete remission with incomplete haematological recovery. Analyses were done on patients who received combination therapy. The study is registered with ClinicalTrials.gov (NCT03194932) and is now enrolling to address secondary and exploratory objectives. FINDINGS Between July 1, 2017, and July 2, 2019, 38 patients were enrolled (aged 3-22 years; median 10 [IQR 7-13]), 36 of whom received combination therapy with dose escalation, with a median follow-up of 7·1 months (IQR 5·1-11·2). The recommended phase 2 dose of venetoclax was found to be 360 mg/m2 (maximum 600 mg) combined with cytarabine (1000 mg/m2 per dose for eight doses), with or without idarubicin (12 mg/m2 as a single dose). Overall responses were observed in 24 (69%) of the 35 patients who were evaluable after cycle 1. Among the 20 patients treated at the recommended phase 2 dose, 14 (70%, 95% CI 46-88) showed complete response with or without complete haematological recovery, and two (10%) showed partial response. The most common grade 3-4 adverse events were febrile neutropenia (22 [66%]), bloodstream infections (six [16%]), and invasive fungal infections (six [16%]). Treatment-related death occurred in one patient due to colitis and sepsis. INTERPRETATION The safety and activity of venetoclax plus chemotherapy in paediatric patients with heavily relapsed and refractory acute myeloid leukaemia suggests that this combination should be tested in newly diagnosed paediatric patients with high-risk acute myeloid leukaemia.

Abstract
Venetoclax is a cytochrome P450, family 3, subfamily A (CYP3A) substrate and was shown to inhibit P-gp efflux transporters in vitro. To quantify the impact of CYP3A inhibition by ritonavir on venetoclax disposition and P-gp inhibition by venetoclax on digoxin pharmacokinetics, two semimechanistic drug-drug interaction (DDI) models of venetoclax were developed using clinical data from healthy volunteers who received subtherapeutic doses of venetoclax with ritonavir 50-100 mg or digoxin 0.5 mg. These models were then used to assess the magnitude of interaction at therapeutic venetoclax doses and to explore various clinical dosing strategies that maintain venetoclax and digoxin concentrations within their respective therapeutic windows. Simulations demonstrated that venetoclax dose reductions of at least 75% are needed when venetoclax is coadministered with ritonavir and administering digoxin at least 2 hours before venetoclax would minimize DDI. Semimechanistic modeling leveraging clinical data is a plausible approach to predict DDI and propose dose adjustments, and administration time of interacting drugs.

Abstract
BACKGROUND AND OBJECTIVE Venetoclax is an oral selective Bcl-2 inhibitor approved for the treatment of patients with chronic lymphocytic leukemia with 17p deletion. Mechanistic and preclinical evidence warranted evaluation of venetoclax for the treatment of systemic lupus erythematosus (SLE). This work characterized the pharmacokinetics of venetoclax in female subjects with SLE. METHODS Single (10-500 mg) and multiple (30-600 mg) escalating doses of venetoclax or matching placebo were evaluated using randomized, double-blind, placebo-controlled designs (6 active and 2 placebo per dose with 73 unique SLE patients enrolled, 25 of whom enrolled twice). The multiple-dose evaluation consisted of two cycles, each with once-daily dosing for 7 days followed by a 21-day washout. Non-compartmental and population pharmacokinetic analyses of venetoclax serial plasma concentrations were conducted. RESULTS Venetoclax exhibited approximately dose-proportional exposures, with peak concentrations observed 4-8 h post-dose. Venetoclax steady-state exposures were achieved by day 4 of dosing, and the median area under the plasma concentration-time curve (AUC) accumulation ratio ranged from 1.1 to 1.5. A two-compartment model with first-order absorption and elimination described venetoclax pharmacokinetics. The estimates (95% bootstrap confidence interval) for venetoclax apparent clearance, central and peripheral volumes of distribution, intercompartmental clearance, absorption rate constant, and lag time were 16.3 L/h (14.6-17.9), 37 L (26-57), 122 L (98-183), 3.7 L/h (2.6-5.0), 0.13 h-1 (0.11-0.17), and 1.6 h (1.6-1.7), respectively. The population estimate for venetoclax terminal-phase elimination half-life was approximately 28 h. CONCLUSIONS In female subjects with SLE, venetoclax displayed pharmacokinetic characteristics consistent with previous observations in subjects with hematologic malignancies. CLINICALTRIALS.

Abstract
Venetoclax is an approved drug for the treatment of some hematological malignancies. Venetoclax can cause reduction in B-lymphocyte counts as an on-target effect. The purpose of this analysis is to quantify the relationship between venetoclax exposure and B-lymphocyte levels to inform dosing of venetoclax in healthy subjects. Data were pooled from 10 studies in healthy subjects with venetoclax doses ranging from 10 mg to 400 mg and food ranging from fasting to high-fat meals. Venetoclax pharmacokinetics (PK) was characterized in 203 subjects using a population approach, as implemented in NONMEM version 7.3 (Icon Development Solutions, Ellicott City, MD, USA). A semimechanistic pharmacodynamic (PD) model with a linear drug effect was fit to the B-lymphocyte data to determine the exposure-response relationship. The population PK and PD model described the observed data adequately. The 200 and 400 mg doses were shown to reduce the B-lymphocyte levels by 24% (15-35%) and 38% (25-54%), respectively. B-lymphocytes recovered to normal levels within an average of 48 (21-64) days and 59 (30-66) days, respectively, with 200 and 400 mg doses. Venetoclax can be safely administered in healthy subjects. The PK-PD model characterized the relationship between venetoclax exposure and reduction in B-lymphocytes and will help design future venetoclax studies in healthy subjects.

Abstract
Non-Hodgkin lymphoma (NHL) includes a variety of closely related malignancies that originate from lymphoid precursors. The majority of NHLs are of B-cell lineage, for which traditional therapy involves chemotherapy in combination with the anti-CD20 monoclonal antibody rituximab. Ongoing research into the pathogenesis of NHL subtypes has given rise to the use of novel agents that target specific molecular pathways. While the incidence of NHL extends over a range of ages from pediatric to elderly settings, the majority of diagnoses occur over age 60 years. Increasing the use of concomitant medication coupled with declining organ function among this group of patients creates pharmacokinetic (PK) challenges in administering a number of agents involved in the treatment of NHL. In addition, since many of the new agents are administered orally, there are a number of added PK factors that must be taken into consideration with their prescribing and administration. This article will review the available literature on the PK and pharmacodynamic properties of agents commonly used in the treatment of NHL, and intends to provide information that can assist with properly using these drugs in this setting.

Abstract
The objective of this research was to characterize the venetoclax exposure-efficacy and exposure-safety relationships and determine its optimal dose in elderly patients with newly diagnosed acute myeloid leukemia (AML) receiving venetoclax in combination with low intensity therapies (hypomethylating agent [HMA; azacitidine or decitabine] or low-dose cytarabine [LDAC]). A total of 212 patients from the HMA study and 92 patients from the LDAC study were included in the exposure-safety analyses. Those who received at least one dose of venetoclax and had at least one measurable response (201 and 83 in the HMA and LDAC studies, respectively) were included in the exposure-efficacy analyses. The probability of response based on International Working Group (IWG) for AML response criteria, adverse events of grade 3 or worse neutropenia or infection or a serious adverse event was modeled using logistic regression analyses to characterize the venetoclax exposure-response relationships. In combination with an HMA, increasing concentrations of venetoclax, up to those associated with a less than or equal to 400-mg once daily (QD) dose, were associated with a higher probability of response, with a trend for flat or decreasing probabilities of response thereafter. In combination with LDAC, increasing concentrations of venetoclax were associated with higher probabilities of response, with no plateau observed. Increasing concentrations of venetoclax were not associated with increasing probability of any safety event except for a slight increase in grade 3 or worse infections with HMAs; however, tolerability issues were observed at doses of greater than or equal to 800 mg QD in each study. Exposure-response analyses support the use of venetoclax 400 mg QD in combination with an HMA and 600 mg QD in combination with LDAC (ie, the next highest dose evaluated below 800 mg in each combination) to safely maximize the probability of response in elderly patients with newly diagnosed AML.

Abstract
INTRODUCTION Venetoclax, a substrate of cytochrome P450 (CYP) 3A and P-glycoprotein (P-gp), is approved for the treatment of patients with chronic lymphocytic leukemia who have received at least one prior therapy. This study evaluated the effect of azithromycin, a commonly used antibiotic in cancer patients and a P-gp inhibitor, on the pharmacokinetics of venetoclax. METHODS In this single-center, open-label, nonfasting, two-period study, 12 healthy female subjects received a single 100 mg dose of venetoclax on day 1 of period 1 and day 3 of period 2. Subjects received azithromycin 500 mg on day 1 and 250 mg once daily on days 2 through 5. Serial blood samples for the determination of venetoclax concentrations were collected after dosing in both periods. Safety was evaluated throughout the study. RESULTS Following coadministration of venetoclax with multiple doses of azithromycin, venetoclax maximum concentration and area under the curve to infinite time were 25% and 35% lower, respectively, compared to venetoclax administered alone. Venetoclax half-life and time to maximum concentration remained relatively unchanged when administered with azithromycin. Venetoclax was well tolerated with no serious adverse events reported. CONCLUSIONS The modest changes in venetoclax exposures when given with azithromycin indicate that no dose adjustment would be needed when venetoclax is coadministered with azithromycin or other drugs with P-gp inhibitory potential. Azithromycin represents an alternative to other antimicrobial agents with higher potential to alter venetoclax pharmacokinetics such as clarithromycin, erythromycin, and ciprofloxacin.

Abstract
Conventional combination therapies have not resulted in considerable progress in the treatment of acute myeloid leukemia (AML). Elderly patients with AML and poor risk factors have grave prognosis. Midostaurin has been recently approved for the treatment of FLT-3-mutated AML. Venetoclax, a BCL-2 inhibitor, has been approved for the treatment of relapsed and/or refractory chronic lymphoid leukemia. Clinical trials on applying venetoclax in combination with cytarabine and other agents to treat various hematological malignancies are currently underway. Here, we present a case of a male patient with poor performance status and who developed AML following allogeneic hematopoietic stem cell transplant for high-risk myelodysplasia. The patient with high risk AML achieved complete response to the combined treatment regimen of low-dose cytarabine and venetoclax. Furthermore, we reviewed current clinical trials on the use of venetoclax for hematological malignancies.

Abstract
Venetoclax is a highly selective, potent BCL-2 inhibitor that is approved for some patients previously treated for chronic lymphocytic leukemia, and has shown promising activity in adult studies across several hematologic malignancies. Preclinical studies have demonstrated venetoclax activity in pediatric patient-derived xenograft models and cell lines; however, clinical studies in pediatric patients have yet to be conducted. The prognosis is poor for children with most relapsed/refractory malignancies, and limited treatment options result in unmet clinical need. Herein, we describe the rationale and design of the first study of venetoclax in pediatric patients with relapsed/refractory malignancies: a Phase I trial investigating the safety and pharmacokinetics of venetoclax monotherapy followed by the addition of chemotherapy (Trial registration: EudraCT 2017-000439-14; NCT03236857).

Abstract
PURPOSE Venetoclax is a selective BCL-2 inhibitor indicated for the treatment of patients with chronic lymphocytic leukemia (CLL). It is predominately metabolized by cytochrome P450 (CYP) 3A. The study objective was to determine the effect of different dosage regimens of ritonavir, a strong CYP3A inhibitor, on the pharmacokinetics of venetoclax in 20 healthy subjects. METHODS In cohorts 1 and 2, subjects received single 10 mg doses of venetoclax in periods 1 and 2 and a single 50- or 100-mg dose of ritonavir in period 2. In cohort 3, subjects received 10-mg venetoclax doses on day 1 of period 1 and days 1 and 11 of period 2, and 50 mg ritonavir daily on days 1 to 14 of period 2. RESULTS Single doses of 50 and 100 mg ritonavir increased the venetoclax maximum concentration (Cmax) 2.3- to 2.4-fold compared to venetoclax alone and the area under the curve (AUC) 6.1- and 8.1-fold, respectively. Daily 50 mg ritonavir resulted in a 2.4- and 7.9-fold increase in venetoclax Cmax and AUC, respectively. Administration of 50 mg ritonavir daily saturated CYP3A inhibition and completely inhibited the formation of the major venetoclax metabolite M27. Time-dependent CYP3A inhibition with daily 50 mg ritonavir was offset by ritonavir CYP3A induction, resulting in a limited net increase in CYP3A inhibition with multiple doses. CONCLUSION After completion of the dose ramp-up, venetoclax dose reductions of at least 75% are recommended when administered concomitantly with strong CYP3A inhibitors to maintain venetoclax exposures within the established therapeutic window for CLL treatment.

Abstract
Venetoclax is a first-in-class orally available, B-cell lymphoma (BCL)-2 inhibitor indicated for the treatment of patients with relapsed/refractory chronic lymphocytic leukemia (CLL) harboring the 17p deletion. We used a novel approach for evaluating venetoclax pharmacokinetics using only sparse sampling in 155 patients enrolled in a phase 2, multicenter, open-label study in CLL patients with the 17p deletion. Patients received venetoclax doses within 30 min after the completion of breakfast or the first meal of the day, with no specific recommendations for the fat content in the meal. Blood samples for venetoclax assay were collected during the ramp-up period and on day 1 of weeks 8, 12, 16, 24, and every 12 weeks thereafter. The mean postdose (8 h) plasma venetoclax concentrations increased with increasing weekly venetoclax dose during the ramp-up period to reach 1.89 µg/ml on week 5 day 1 at the 400 mg dose. The mean predose concentration at the 400 mg dose ranged between 0.69 and 0.99 µg/ml across visits between weeks 8 and 120. Repeated-measures analysis detected no statistical significance (P≥0.05) for the mean predose concentrations at any of the times tested from weeks 8 to 24. The study shows that the pharmacokinetic profile of venetoclax in CLL patients with the 17p deletion is comparable to the overall CLL as well as non-Hodgkin's lymphoma patient populations. Furthermore, no specific recommendation in terms of fat content in the meal is needed for the intake of venetoclax in patients with CLL.

Abstract
Treatment of myeloma is a long-term treatment mainly based on all-oral combinations of drugs. Because oral drugs have a more complex pharmacokinetics compared with IV treatments, an appropriate knowledge of the factors that may alter their systemic exposure is of particular clinical relevance. Both drug-drug interactions, food-effect, and dose-adaptation in renal and hepatic impairment may influence the systemic drug levels with a potential impact on drug efficacy or safety. Moreover, a better control of drug exposure may improve the side effect profiles of these treatments with a favourable impact on patient compliance. Furthermore, as long-term treatments, these drugs may also alter the systemic exposure of coadministered medications in these rather old patients. The aim of this review was to identify the factors modifying the systemic exposure of oral drugs used in myeloma by focusing on the pharmacokinetic drug-drug interactions and the effects of renal and hepatic impairment and of food impact.

Abstract
Venetoclax has been approved in the United States, Europe, Canada, and Australia for appropriate patients with difficult-to-treat chronic lymphocytic leukemia (CLL). The objective of this phase 1 study was to evaluate the pharmacokinetics of venetoclax in Chinese subjects to inform the dose selection of venetoclax in a phase 2 study of patients with relapsed/refractory (R/R) CLL in China. Twelve healthy first-generation Han Chinese subjects received a single 100-mg dose of venetoclax following a low-fat breakfast. Pharmacokinetic parameters were estimated using noncompartmental methods. After a single dose of venetoclax in healthy Chinese subjects, the median time to peak concentration was 6 hours (range, 4 to 6 hours), and the mean ± SD Cmax , AUCinf , and terminal half-life were 1.0 ± 0.32 μg/mL, 12.6 ± 5.4 μg·h/mL, and 18.4 ± 2.97 hours, respectively. On average, venetoclax Cmax and AUCinf values were 94% and 66% higher, respectively, in Chinese subjects compared with those observed historically for non-Asian subjects receiving the same dose. Based on these pharmacokinetic results and the established exposure-response relationship of venetoclax in non-Asian CLL subjects, a 400-mg once-daily dosage regimen was selected for evaluating the venetoclax pharmacokinetics, efficacy, and safety in the venetoclax phase 2 open-label study in Chinese subjects with R/R CLL.

Abstract
1. Venetoclax is a novel, small molecule B-cell lymphoma-2 (BCL-2) inhibitor that has demonstrated clinical efficacy in a variety of haematological malignancies. Since venetoclax is an inhibitor of P glycoprotein (P-gp) transporter, a study was conducted in healthy, female volunteers to evaluate the effect of venetoclax on the pharmacokinetics of digoxin, a P-gp probe substrate. 2. Volunteers received a single oral dose of digoxin (0.5 mg) with or without a single oral dose of venetoclax (100 mg). Serial blood samples were obtained for pharmacokinetic assessments of digoxin and venetoclax and serial urine samples were obtained for measurement of digoxin concentrations. Safety was assessed throughout the study. 3. Coadministration of digoxin and venetoclax increased digoxin maximum observed plasma concentration (Cmax) by 35% and area under the plasma-concentration time curve (AUC0-∞) by 9%. Digoxin half-life, renal clearance and the fraction excreted unchanged in urine remained relatively similar. The results of this study indicate that venetoclax can increase the concentrations of P-gp substrates. Narrow therapeutic index P-gp substrates should be administered six hours prior to venetoclax to minimise the potential interaction.

Abstract
Abstract
The B-cell leukemia/lymphoma-2 (BCL-2) family of proteins governs the intrinsic pathway of mitochondrial apoptosis. Dysregulation of BCL-2 has long been known to be a crucial part of the pathophysiology of B-cell lymphomas; however, several early attempts to target this pathway therapeutically were unsuccessful because of toxicity, lack of efficacy, or both. Recently, a highly potent and selective oral BCL-2 antagonist, venetoclax, was approved in chronic lymphocytic leukemia, where it has proven to be highly active, even in patients with high-risk del(17p) disease. Venetoclax has also demonstrated efficacy in other B-cell non-Hodgkin lymphoma subtypes, in particular mantle cell lymphoma and follicular lymphoma. Here, I review the history of targeting BCL-2 in B-cell lymphomas, and I discuss recent data on venetoclax used as monotherapy and in combination with monoclonal antibodies, chemotherapy, and other novel agents. I also discuss how genomic and functional approaches such as BH3 profiling may allow us to prioritize novel-agent combinations for further study in clinical trials. These approaches may also help us to understand resistance mechanisms to BCL-2–selective therapy and how to overcome resistance. Finally, I provide my perspective on how to move BCL-2–directed therapies forward toward a goal of developing well-tolerated, time-limited combination regimens with curative potential for patients with B-cell lymphomas.

Abstract
Exposure-response analyses were performed for a venetoclax monotherapy study in 106 patients with varying subtypes of non-Hodgkin lymphoma (NHL) (NCT01328626). Logistic regression, time-to-event, and progression-free survival (PFS) analyses were used to evaluate the relationship between venetoclax exposure, NHL subtype and response, PFS, or occurrence of serious adverse events. Trends for small increases in the probability of response with increasing venetoclax exposures were identified, and became more evident when assessed by NHL subtype. Trends in exposure-PFS were shown for the mantle cell lymphoma (MCL) subtype, but not other subtypes. There was no increase in the probability of experiencing a serious adverse event with increasing exposure. Overall, the results indicate that venetoclax doses of 800-1200 mg as a single agent may be appropriate to maximize efficacy in MCL, follicular lymphoma, and diffuse large B-cell lymphoma subtypes with no expected negative impact on safety.

Abstract
Patients with chronic lymphocytic leukemia with the 17p deletion have a poor prognosis and treatment options are limited. Venetoclax, a novel B-cell lymphoma-2 inhibitor, has been approved for treatment-experienced chronic lymphocytic leukemia patients with the 17p deletion. A phase 1 dose-escalation study to 400 mg daily showed overall response rates across all doses of 79% with a complete response achieved in 20%. A phase 2 multicenter open-label study demonstrated overall response rate of 79.4% of patients (95% confidence interval 70.5–86.6) with median duration of follow-up of 12.1 months (IQR 10.1-14.2). Tumor lysis syndrome has been observed during initiation and titration. Assessing risk of tumor lysis syndrome prior to therapy initiation is essential to provide appropriate prophylactic medications. Neutropenia, potentially warranting dose reduction or discontinuation, has been observed. Venetoclax has demonstrated activity in other leukemias, multiple myeloma, and lymphomas. Venetoclax has shown response, and is well tolerated in patients with highly resistant chronic lymphocytic leukemia. It has the potential to be part of the treatment armamentarium for other malignancies.

Abstract
Exposure-response analyses of venetoclax in combination with bortezomib and dexamethasone in previously treated patients with multiple myeloma (MM) were performed on a phase Ib venetoclax dose-ranging study. Logistic regression models were utilized to determine relationships, identify subpopulations with different responses, and optimize the venetoclax dosage that balanced both efficacy and safety. Bortezomib refractory status and number of prior treatments were identified to impact the efficacy response to venetoclax treatment. Higher venetoclax exposures were estimated to increase the probability of achieving a very good partial response (VGPR) or better through venetoclax doses of 1,200 mg. However, the probability of neutropenia (grade ≥3) was estimated to increase at doses >800 mg. Using a clinical utility index, a venetoclax dosage of 800 mg daily was selected to optimally balance the VGPR or better rates and neutropenia rates in MM patients administered 1-3 prior lines of therapy and nonrefractory to bortezomib.

Abstract
AIMS To examine the effect of a strong cytochrome P450 (CYP) 3A inhibitor, ketoconazole, on the pharmacokinetics, safety and tolerability of venetoclax. METHODS Twelve patients with non-Hodgkin lymphoma (NHL) were enrolled in this Phase 1, open-label, fixed-sequence study. Patients received a single 50 mg dose of venetoclax orally on Day 1 and Day 8, and a 400 mg once daily dose of ketoconazole on Days 5-11. Blood samples were collected predose and up to 96 h after each venetoclax dose on Day 1 and Day 8. RESULTS Eleven patients had evaluable pharmacokinetic data and were therefore included in the statistical analyses. Compared to administration of a single 50 mg dose of venetoclax alone, ketoconazole increased the venetoclax mean maximum observed plasma concentration (Cmax ) and area under the plasma concentration-time curve from time 0 to infinity (AUC∞ ) by 2.3-fold (90% confidence interval [CI]: 2.0-2.7) and 6.4-fold (90% CI: 4.5-9.2; range: 2- to 12-fold), respectively. CONCLUSIONS Coadministration of venetoclax with multiple doses of ketoconazole resulted in a significant increase of venetoclax exposures, strongly suggesting that CYP3A plays a major role in elimination of venetoclax in patients. These results suggest the need to avoid concomitant use with strong and moderate inhibitors or inducers of CYP3A during the venetoclax ramp-up phase in chronic lymphocytic leukaemia (CLL) patients. For patients who have completed the ramp-up phase, a modification in venetoclax dose for use with strong and moderate inhibitors or inducers of CYP3A is recommended.
