Official title

A Phase 1b, Dose Escalation/Dose Expansion, Multicenter, Open-Label Study to Assess the Safety and Tolerability of OPN-6602 Monotherapy and in Combination With Dexamethasone in Subjects With Relapsed and/or Refractory Multiple Myeloma

Overview

Phase 1b, open-label study evaluating the safety, tolerability, pharmacokinetics, preliminary antitumor activity, and pharmacodynamics of OPN-6602 monotherapy and in combination with dexamethasone in subjects with relapsed and/or refractory MM.

Interventions

  • Drug OPN-6602
    orally active, small molecule inhibitor of EP300 and CBP bromodomain; dosed daily
  • Drug Dexamethasone
    Synthetic glucocorticoid; 40 mg Days 1, 8, 15 of each cycle

Primary outcome measures

  • Number and type of dose-limiting toxicities (DLTs) [Time frame: Through up to approximately 30 days following last dose of OPN-6602]
  • Number and type of treatment-emergent adverse events (TEAEs) [Time frame: Through up to approximately 30 days following last dose of OPN-6602]
  • Number of Participants With Clinical Laboratory Test Abnormalities [Time frame: Through up to approximately 30 days following last dose of OPN-6602]

Eligibility criteria

Inclusion criteria

  • Confirmed diagnosis of multiple myeloma (MM)

  • Prior allogeneic stem cell transplantation or solid organ transplantation within 12 months of first dose of study drug; subjects receiving immunosuppressive medication for active graft vs host disease will be excluded.
  • Prior chemotherapy, targeted anticancer or radiation therapy within 2 weeks prior to first dose of study drug
  • Concomitant high-dose corticosteroids (except subjects on chronic steroids given for disorders other than myeloma)
  • Known central nervous system involvement by multiple myeloma
  • Active known second malignancy with exception of adequately treated basal cell carcinoma, squamous cell carcinoma of the skin, or in situ cervical cancer; adequately treated Stage 1 cancer from which the subject is currently in remission and has been in remission for ≥2 years; low-risk prostate cancer with a Gleason score <7 and a PSA level <10 ng/mL; any other cancer from which the subject has been disease-free for ≥3 years
  • Ongoing systemic infection requiring parenteral treatment
