Talquetamab in Combination With Iberdomide and Dexamethasone for Relapsed or Refractory Multiple Myeloma
Trial Parameters
Brief Summary
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.
