Brief summary
The purpose of this study is to determine whether the combination of Iberdomide, Isatuximab and Dexamethasone combined improves response to treatment.

Who is it for?
You may be eligible to participate in this trial if you are aged 18 years or over, you have been diagnosed with multiple myeloma and you have demonstrated disease progression within 12 months of commencing first-line therapy.

Study Details
Eligible participants will receive Iberdomide, Isatuximab and Dexamethasone. Treatment (each cycle is 28 days) will be given until disease progression, unacceptable toxicity, or withdrawal of consent.
Participants will be required to have blood samples taken at the beginning of each cycle along with a medical exam in order for researchers to monitor whether the treatment is safe and whether it is effectively treating the myeloma.
It is hoped that the findings of this trial will establish the benefits of this combination of treatment of multiple myeloma patients early in the course of their disease.
