Ibrutinib, Lenalidomide, and Dexamethasone in Treating Patients With Multiple Myeloma Ineligible for Transplant


About this study

This phase I/II trial studies the best dose and side effects of ibrutinib when given together with lenalidomide and dexamethasone and how well they work in treating patients with multiple myeloma that are not eligible for transplant. Ibrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ibrutinib, lenalidomide, and dexamethasone may work better in treating patients with multiple myeloma.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
