Hydroxychloroquine, Cyclophosphamide, Dexamethasone, and Sirolimus in Treating Patients With Relapsed or Refractory Multiple Myeloma

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial studies the side effects and best dose of hydroxychloroquine when given together with cyclophosphamide, dexamethasone, and sirolimus in treating patients with multiple myeloma that has come back after a period of improvement or does not respond to treatment. Biological therapies, such as hydroxychloroquine, may stimulate the immune system in different ways and stop cancer cells from growing. Sirolimus may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, stopping them from dividing, or by stopping them from spreading. Giving hydroxychloroquine together with sirolimus, cyclophosphamide, and dexamethasone may be a better treatment for multiple myeloma.
