Clinical Activity of Metformin With High-dose of Dexamethasone in Relapse Multiple Myeloma

Summary

This phase II trial study assessing the activity of metformin when given together with high dose of dexamethasone in treating patients with multiple myeloma (MM) that has relapse or refractory to previous treatment. High dose of dexamethasone (HDdexa) is used to treat relapse/refractary patients with myeloma and metformin also demonstrated synergistic activity with dexamethasone to eradicate MM cells in vitro and in vivo. Metformin hydrochloride, used for diabetes, may also help kill tumor cells. Giving dexamethasone with metformin may kill more MM cells and increase the response rate to HDdexa.
