A Phase I/II Study of Elotuzumab and Iberdomide and Dexamethasone Post Idecabtagene Vicleucel in Relapsed and Refractory Multiple Myeloma

Description

The aim of this research study is to evaluate the efficacy of Elotuzumab and Iberdomide therapy post-Idecabtagene Vicleucel in participants with relapsed and refractory multiple myeloma. The names of the study drugs involved in this study are: * Iberdomide (a type of cereblon E3 ligase modulator) * Elotuzumab (a type of monoclonal antibody) * Dexamethasone (a type of steroid)This is a phase I/II, open-label, non-randomized, single-stage study to evaluate the efficacy of Elotuzumab and Iberdomide therapy post-Idecabtagene Vicleucel in participants with relapsed and refractory multiple myeloma. Iberdomide has demonstrated some antitumor activity in laboratory studies. The U.S. Food and Drug Administration (FDA) has approved Elotuzumab as a treatment option for Multiple Myeloma. Dexamethasone, also FDA approved, is a type of steroid and is usually combined with other chemotherapy for the treatment of blood cancers, such as myeloma and leukemias. The U.S. Food and Drug Administration (F

Exclusion Criteria * Prior exposure to Iberdomide * Participation in other clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial. * Diagnosed or treated for another malignancy within 3 years prior to enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in-situ malignancy, or low risk prostate cancer after curative therapy * Known central nervous system involvement. * Systemic treatment, within 14 days before the first dose of treatment, with strong CYP3A or inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of St. John's wort OR systemic treatment within 14 days of the first dose of treatment with a strong inhibitor of CYP1A2 (ciprofloxacin, fluvoxamine, cimetidine, enoxacin, ethynyl estradiol, mexiletine) * Any medical or psychiatric illness/social situation that in the Investigator's opinion, would impose excessive risk to the patient, would adversely affect his/her participating in this study or would limit compliance with study requirements. * Currently active graft versus host disease of any stage or grade after allogeneic stem cell transplantation * Prior major surgical procedure or radiation therapy within 14 days of initiation of therapy. * Those who require a limited course of radiation for management of bone pain more than 14 days out from initiation of therapy are not excluded * Any active, or uncontrolled cardiovascular conditions, including but not limited to uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, grade 3 thromboembolic event or myocardial infarction within the past 6 months. * The following therapies within the stated time frames prior to initiation of therapy: * Previous cytotoxic therapies, including cytotoxic investigational agents, for multiple myeloma within 21 days (42 days for nitrosoureas). * The use of live vaccines within 30 days. * IMiDs or proteasome inhibitors within 14 days. * Other investigational therapies and/or monoclonal antibodies within 4 weeks. * Prior peripheral stem cell transplant within 12 weeks. * Prior allogeneic stem cell transplantation with active graft-versus-host-disease. * Those who require a limited course of daily requirement for corticosteroids (equivalent to \>10 mg/day prednisone, though \>10mg/day is acceptable if physiological levels require, so long as the dose is stable for at least 7 days prior to initiation of therapy. Inhalation corticosteroids are exempt from this criterion. * Lower amounts of corticosteroids that are not part of a daily requirement within 14 days prior to initiating therapy * Concurrent symptomatic amyloidosis or plasma cell leukemia * POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes) * Infection requiring systemic antibiotic therapy or other serious infection within 7 days of starting therapy. * Those who are on prophylactic antibiotics only, or on antibiotics and have confirmation of resolution of active infection are eligible. * Known seropositive for active viral infection with human immunodeficiency virus (HIV) hepatitis B (HBV) or hepatitis C viral (HCV).
