简要总结
This phase I/Ia trial finds the best dose and side effects of venetoclax given in combination with ixazomib citrate and dexamethasone in treating patients with light chain amyloidosis that has come back (relapsed) or does not respond to treatment (refractory) and who have an abnormal genetic change [translocation t(11;14)]. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Ixazomib citrate is in a class of medications called proteasome inhibitors. It works by helping to kill cancer cells. Anti-inflammatory drugs such as dexamethasone reduce inflammation by lowering the body's immune response and are used with other drugs in the treatment of some types of cancer. Combination therapy with venetoclax, ixazomib citrate and dexamethasone may be effective in treatment of relapsed or refractory light chain amyloidosis.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the safety and tolerability of venetoclax, MLN9708 (ixazomib citrate), and dexamethasone when used in combination.
II. To determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of venetoclax, MLN9708 (ixazomib citrate), and dexamethasone when used in combination.
SECONDARY OBJECTIVES:
I. To observe and record anti-tumor activity. II. To obtain a preliminary estimate of the anti-light chain amyloidosis (AL) activity as assessed by incidence of complete hematologic response (CR) and overall hematologic response (partial response [PR], very good partial response [VGPR], and CR).
