About this trial
This phase Ib trial tests the safety, side effects, and best dose of iberdomide in combination with teclistamab in treating multiple myeloma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Iberdomide is a medication that belongs to a group of drugs known as cereblon E3 ligase modulators. Iberdomide works by targeting and destroying proteins that help myeloma cancer cells to survive. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as teclistamab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Giving iberdomide in combination with teclistamab may be safe and tolerable in treating patients with relapsed or refractory multiple myeloma.
Eligibility criteria
Qualifiers
Patients must have histologically or cytologically confirmed multiple myeloma (MM), as defined in the International Myeloma Working Group (IMWG) criteria
If patients have undergone autologous stem cell transplant (SCT), day 0 of SCT must be > 100 days to be eligible for the study
Patients must have had disease progression after ≥ 4 prior lines of anti-myeloma treatments including one proteasome inhibitor (e.g., bortezomib, carfilzomib, ixazomib), one immunomodulatory imide drug (ImiD) (e.g., thalidomide, lenalidomide, pomalidomide [POM]), and one anti-CD38 monoclonal antibody (e.g., daratumumab, isatuximab)
Serum M-protein ≥ 0.5 g/dL (≥ 5 g/L)
Disqualifiers
Patients who have active plasma cell leukemia, active amyloid light chain (AL) (primary) amyloidosis, active POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma proliferative disorder, myeloma protein, and skin changes), and Waldenstrom macroglobulinemia are ineligible
If a patient develops recurrent/refractory (R/R) disease while receiving the most recent line of therapy, there is no need for a washout period
Patients who have had prior anti-BCMA directed bispecific antibody (BsAb) therapy exposure (prior treatment with anti-BCMA directed antibody drug conjugate, anti-BCMA-directed chimeric antigen receptor (CAR) T cell therapy, and prior non-BCMA-targeting BsAb are permitted)
Patients who have had prior treatment with a cereblon E3 ligase modulator, including mezigdomide, iberdomide, and CFT7455 (all currently in clinical development)
