Iberdomide Combination Therapy (KID)

This is a multi-institution, open label, phase I/II study of Iberdomide, Carfilzomib, and dexamethasone (KID) in patients with newly diagnosed transplant eligible MM.

As part of a dose escalation phase, the first 10 patients will be enrolled at dose level -1 (Iberdomide 1.1 mg po daily days 1-21). Two months after the first 10 patients have completed at least 2 cycles of therapy in dose level -1, an Independent Safety Review Committee will review the safety data. Assuming the combination is determined to have adequate safety and tolerability, 10 patients will be enrolled at dose level 1 (Iberdomide 1.3 mg po daily days 1-21). After an independent safety review two months after 10 patients have completed at least 2 cycles of therapy in dose level 1, the remaining 46 patients will be enrolled at dose level 2 (Iberdomide 1.6 mg po daily days 1-21).

Treatment will continue for up to 4 cycles (28 days) at the physician's discretion followed by the Autologous Stem Cell Transplant. Patients will be followed every 3 months for up to 2 years, or until disease progression or the start of a new line of therapy.
