Treatment: Drugs - Iberdomide
Treatment: Drugs - Dexamethasone

Experimental: Substudy 2: Dose Escalation and Expansion - In the pre-phase, participants will receive 2 step-up doses and a target dose of cevostamab. The step-up dose will be given on Day(D)1 and D4. The target dose will be given on D8. Subsequently the target dose will be administered on D1 and D15 for cycles 1-6 and D1 of cycle 7 onwards. Each cycle is 28 days. Lenalidomide will be administered by mouth (PO) on a 28-day cycle.

Experimental: Substudy 4: Dose Escalation and Expansion - In the pre-phase, participants will receive 2 step-up doses and a target dose of cevostamab. The step-up dose will be given on D1 and D4. The target dose will be given on D8. Subsequently the target dose will be administered on D1 of each cycle, every 3 weeks (Q3W). Each cycle is 21 days. Iberdomide will be administered PO on a 21-day cycle.

During the dose expansion phase, cevostamab will be administered following the same dosing schedule as the dose escalation phase. The target dose will be determined after the escalation phase. Iberdomide will be administered PO on a 21-day cycle.

Summary
Brief summary
CO43923 is a platform study that will evaluate the safety, efficacy, and pharmacokinetics (PK) of multiple treatment combinations, as monotherapy or in combination, in participants with multiple myeloma (MM). The study is designed with the flexibility to open new treatment substudies as new treatments become available. Information regarding the opened substudies are found below.
