Study of Ciforadenant in Combination With Daratumumab in Patients With Relapsed or Refractory Multiple Myeloma

Trial Status: Active

This is a Phase 1b open-label study of ciforadenant, an oral, small molecule inhibitor targeting adenosine-2A receptors (A2AR), on safety / tolerability and efficacy in combination with daratumumab, a monoclonal antibody targeting CD38, in relapsed or refractory multiple myeloma.

  • Active myeloma requiring systemic treatment.
  • Measurable disease per protocol.
  • ECOG performance status of 0 - 2.
  • Life expectancy of at least 3 months.

  • History of select prior malignancies.
  • Previous intolerance to daratumumab or any study drug.
  • Received an allogeneic stem cell transplant within 12 months, or an autologous stem cell transplant within 6 months, or have ongoing toxicity related to transplant.
  • Have an active infection or serious comorbid medical condition.
  • Any live attenuated vaccination against infectious diseases (e.g., influenza, varicella) within 4 weeks of initiation of study treatment; uncontrolled human immunodeficiency virus, or positive tests for hepatitis B or hepatitis C.
