Study Evaluating ABT-199 in Subjects With Relapsed or Refractory Multiple Myeloma

Overview

  • Study type

    Interventional
  • Study phase

    II
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The phase 1 primary objectives of this study are to assess the safety profile, characterize pharmacokinetics (PK) and determine the dosing schedule, maximum tolerated dose (MTD), and recommended phase 2 dose (RPTD) of ABT-199 (venetoclax) when administered in subjects with relapsed or refractory multiple myeloma. This study will also assess the safety profile and PK of venetoclax in combination with dexamethasone in subjects with t(11;14)-positive multiple myeloma. The phase 2 primary objective is to further evaluate the objective response rate (ORR) and very good partial response or better rate (VGPR+) in subjects with t(11;14)-positive multiple myeloma and to evaluate patient reported outcomes.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

See eligibility criteria

Inclusion Criteria:

  • ECOG (Eastern Cooperative Oncology Group) performance score of 1 or 0. Subjects in the Phase 2 portion: ECOG performance score of 2, 1, or 0.
  • Diagnosis of multiple myeloma previously treated with at least one prior line of therapy. Induction therapy followed by stem cell transplant and maintenance therapy will be considered a single line of therapy. For Safety Expansion, subjects must have been previously treated with a proteasome inhibitor (e.g., bortezomib) and an immunomodulatory agent (e.g., thalidomide, lenalidomide). For Venetoclax-Dexamethasone Combination, subjects must have been been previously treated with a proteasome inhibitor (e.g., bortezomib) and an immunomodulatory agent (e.g., thalidomide, lenalidomide) AND have t(11;14)-positive multiple myeloma per the central lab testing. For Phase 2, subjects must have documented MM positive for t(11;14) translocation. If testing has been performed by non-central lab, retesting must be confirmed by central lab. Subjects must have evidence of disease progression on or within 60 days of last dose of most recent previous treatment based on IMWG criteria AND subjects must have previously received at least 3 prior lines of therapy, including and immunomodulatory drug, a proteasome inhibitor, daratumumab, and glucocorticosteroids. Daratumumab combination regimen MUST be one of the prior lines of therapy (for this study, daratumumab plus corticosteroids will not be considered a combination regimen).
  • Measurable disease at Screening: Serum monoclonal protein of at least 1.0 g/dL (10g/L) by protein electrophoresis or at least 200 mg of monoclonal protein in the urine on 24-hr electrophoresis or serum immunoglobulin free light chain of at least 10 mg/dL and abnormal serum immunoglobulin kappa to lambda free light chain ratio.
  • Subjects with a history of autologous or allogenic stem cell transplantation must have adequate peripheral blood counts independent of any growth factor support, and have recovered from any transplant related toxicity(s) and be at least 100 days post-autologous transplant prior to first dose of study drug or at least 6 months post-allogenic transplant prior to first dose of study drug and not have active graft-versus-host disease (GVHD), i.e., requiring treatment.
  • Meet the following laboratory parameters, per the reference range: ANC of at least 1000/μL (Subjects may use growth factor support to achieve ANC eligibility criteria), AST and ALT not higher than 3 x ULN, Calculated creatinine clearance of at least 30 mL/min using a modified Cockcroft-Gault calculation, platelet count of at least 30,000 mm³ (independent of transfusion for 2 weeks), hemoglobin of at least 8.0 g/dL (subjects may receive blood transfusion to achieve hemoglobin eligibility criteria), and total bilirubin not higher than 1.5 x ULN (subjects with Gilbert's Syndrome may have bilirubin higher 1.5 x ULN with approval of sponsor medical monitor).

Exclusion Criteria:

  • Exhibits evidence of other clinically significant uncontrolled condition(s), including, but not limited to: uncontrolled systemic infection (viral, bacterial, or fungal), diagnosis of fever and neutropenia within 1 week prior to first dose of study drug.
  • Cardiovascular disability status of New York Heart Association Class greater than or equal to 3.
  • Significant history of renal, neurologic, psychiatric, endocrinologic, metabolic, immunologic, cardiovascular or hepatic disease, within the last 6 months that, in the opinion of the investigator, would adversely affect his/her participation in the study.
  • History of other active malignancies other than multiple myeloma within the past 3 years prior to study entry, with the following exceptions: adequately treated in situ carcinoma of the cervix uteri, basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin, Prostate cancer gleason grade 6 or lower AND with stable prostate specific antigen (PSA) levels off treatment, previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.
  • Known HIV infection.
  • Active hepatitis B or C infection
