Selvigaltin With Standard of Care Treatment for the Treatment of Relapsed/Refractory Multiple Myeloma

This phase I trial studies the side effects and best dose of selvigaltin when given together with standard of care treatment (daratumumab-hyaluronidase, carfilzomib, dexamethasone) in treating patients with multiple myeloma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Selvigaltin works by blocking the activity of a protein called galectin-3. Galectin-3 is involved in various cellular processes, including inflammation and tissue scarring, which is associated with worse outcomes in several forms of cancer. By blocking the activity of galectin-3, selvigaltin may help reduce inflammation and tissue scarring. Daratumumab-hyaluronidase is a drug composed of daratumumab and hyaluronidase. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Hyaluronidase helps deliver the daratumumab to CD38-expressing cancer cells. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Giving selvigaltin with standard of care treatment may be safe, tolerable, and/or effective in treating patients with relapsed or refractory multiple myeloma.
