Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine the best dose of ACY-1215 in combination with lenalidomide and dexamethasone in patients with relapsed or relapsed/refractory multiple myeloma. Once determined, the purpose of this study will be to determine the efficacy of ACY-1215 in combination with lenalidomide and dexamethasone in patients with relapsed multiple myeloma who have had 1-3 prior therapies and who are not lenalidomide-refractory.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is phase 1, single-arm, multicenter, open-label study in patients with relapsed or relapsed/refractory MM. The study employs a sequential group dose-escalation design to determine the DLT and MTD of ACY-1215 in combination with lenalidomide and dexamethasone, all administered orally (PO). The safety, tolerability, single- and multiple-dose PK, pharmacodynamics, and anti-tumor activity of ACY 1215 in combination with lenalidomide and dexamethasone also will be evaluated.

Each cohort will enroll 3 patients. Study drug doses will be escalated sequentially after the Safety Review Committee (SRC) reviews safety data collected in C1 (28 days) from patients enrolled at the current dose level as well as emerging data from ongoing studies of ACY-1215. If there are no DLTs (as defined in Section 5.2.6) during C1 or concerns based on data from other ongoing studies, the study will proceed with dose escalation to the next cohort following safety data review by the SRC. If 1 of 3 patients has a DLT, then up to 3 additional patients will be enrolled in that cohort; if none of the additional 3 patients experience a DLT during C1, escalation may then continue to the next cohort following SRC review. If 2 or more patients have DLTs during C1, the DLT dose level will have been reached.

The MTD is defined as the dose level immediately below the DLT dose level. A total of up to 6 additional patients may be enrolled at the MTD or other appropriate dose level to obtain additional AE, PK, pharmacodynamic, and anti-tumor activity data on ACY 1215 in combination with lenalidomide and dexamethasone.
