简要总结
This phase Ib trial studies the side effects and best doses of carfilzomib and bendamustine hydrochloride when given together with dexamethasone in treating patients with multiple myeloma that has returned or does not respond to treatment. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as bendamustine hydrochloride, work to stop the growth of cancer cells by killing the cells. Biological therapies, such as dexamethasone, may stimulate the immune system and stop cancer cells from growing. Giving carfilzomib, bendamustine hydrochloride, and dexamethasone may be a better way to treat multiple myeloma.
详细描述
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of carfilzomib in combination with bendamustine (bendamustine hydrochloride) and dexamethasone, up to a maximum bendamustine dose of 90 mg/m^2.
SECONDARY OBJECTIVES:
I. To evaluate the safety of carfilzomib in combination with bendamustine and dexamethasone, at the MTD.
II. To evaluate the response rate and duration of response of carfilzomib in combination with bendamustine and dexamethasone, in patients with relapsed and or refractory multiple myeloma.
