Conditions: Relapsed or Refractory Multiple Myeloma
Allocation: NON_RANDOMIZED | Intervention model: PARALLEL
Enrollment: 31
Healthy volunteers: no

Brief summary:
The purpose of this Phase I study of vorinostat in combination with lenalidomide and dexamethasone in participants with relapsed or refractory multiple myeloma is to determine the maximum tolerated dose (MTD) as estimated by the incidence of dose-limiting toxicities (DLTs) and recommended Phase 2 dose (RP2D) as estimated by the incidence of drug-related adverse events (AEs).

Detailed description:

Arms:
arm 1: Participants will receive vorinostat 300 mg orally once-daily (QD) on Days 1-7 and Days 15-21; lenalidomide 10 mg orally QD on Days 1-21 and dexamethasone 40 mg orally QD on Days 1, 8, 15 and 22 of each 28-day cycle for up to 8 cycles. Qualified participants who don't have disease progression can continue treatment after 8 cycles at the same dose and schedule, until progressive disease or unacceptable toxicity. arm 2: Participants will receive vorinostat 400 mg orally QD on Days 1-7 and Days 15-21; lenalidomide 10 mg orally QD on Days 1-21 and dexamethasone 40 mg orally QD on Days 1, 8, 15 and 22 of each 28-day cycle for up to 8 cycles. Qualified participants who don't have disease progression can continue treatment after 8 cycles at the same dose and schedule, until progressive disease or unacceptable toxicity. arm 3: Participants will receive vorinostat 400 mg orally QD on Days 1-7 and Days 15-21; lenalidomide 15 mg orally QD on Days 1-21 and dexamethasone 40 mg orally QD on Days 1, 8, 15 and 22 of each 28-day cycle for up to 8 cycles. Qualified participants who don't have disease progression can continue treatment after 8 cycles at the same dose and schedule, until progressive disease or unacceptable toxicity. arm 4: Participants will receive vorinostat 400 mg orally QD on Days 1-7 and Days 15-21; lenalidomide 20 mg orally QD on Days 1-21 and dexamethasone 40 mg orally QD on Days 1, 8, 15 and 22 of each 28-day cycle for up to 8 cycles. Qualified participants who don't have disease progression can continue treatment after 8 cycles at the same dose and schedule, until progressive disease or unacceptable toxicity. arm 5: Participants will receive vorinostat 400 mg orally QD on Days 1-7 and Days 15-21; lenalidomide 25 mg orally QD on Days 1-21 and dexamethasone 40 mg orally QD on Days 1, 8, 15 and 22 of each 28-day cycle for up to 8 cycles. Qualified participants who don't have disease progression can continue treatment after 8 cycles at the same dose and schedule, until progressive disease or unacceptable toxicity.
