Relapsed Multiple Myeloma

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.

This phase I trial will evaluate the safety, side effects, and best dose of talquetamab in combination with iberdomide and dexamethasone in treating patients with multiple myeloma that has come back after a period of improvement (relapsed) or has not responded to previous treatment (refractory). There is currently a significant unmet need for patients with relapsed or refractory multiple myeloma (RRMM) who are triple class refractory and have been exposed to B-cell maturation antibody (BCMA) targeted therapy. These patients currently have limited treatment options and poor survival. Talquetamab is an FDA approved drug that can bring T-cells to the myeloma cell, resulting in myeloma cell death. Iberdomide is an investigational drug and works by targeting and destroying proteins that help myeloma cancer cells to survive. Dexamethasone is a corticosteroid, is similar to a natural hormone produced by the adrenal glands to reduce inflammation (swelling, heat, redness, and pain) and is used to in helping to treat certain types of cancer including myeloma.

The investigators want to find out whether or not giving patients who have relapsed or refractory multiple myeloma (MM) the experimental medication combination iberdomide, carfilzomib, daratumumab, and dexamethasone (Iber-KDd) may produce better results than the current (standard of care) treatments. This study will examine the tolerability and efficacy of this combination therapy for all participants and the ability of this combination therapy to shrink or prevent MM from returning.

Bispecific antibody therapies targeting BCMA (B-cell maturation antigen) represent a novel therapeutic approach for patients with multiple myeloma. They are currently used in cases of refractory multiple myeloma but are also being investigated in earlier lines of treatment. However, these new therapies can lead to deeper immunosuppression and exacerbate an underlying immunosuppressive state in patients with multiple myeloma. As a result, infectious complications are common with these therapies and are a significant concern. Therefore, preventing infections in this population is crucial. However, data on the best strategies for prevention are currently lacking.

This is an open label, Phase 1/2, first-in-human, multiple ascending dose, and dose-expansion study of IDP-023 administered as a single agent and in combination with or without interleukin-2 (IL-2), and with or without isatuximab, daratumumab or rituximab to evaluate the safety, tolerability and preliminary antitumor activity in patients with advanced hematologic cancers.
