Allocation: NON_RANDOMIZED | Intervention model: SEQUENTIAL
Enrollment: 18
Healthy volunteers: no

Brief summary:
The primary purpose of this trial is to determine the maximum tolerated dose (MTD), or the maximum acceptable dose (MAD) and evaluate the dose limiting toxicity (DLT) of oral suberoylanilide hydroxamic acid in participants with solid tumors.

Detailed description:

Arms:
arm 1: During Cycle 1, participants receive a single oral dose of vorinostat 100 mg on Day 1 in a fasted state, Day 3 in a fed state, and Day 19 in a fed state. On Days 5-18, participants receive vorinostat 100 mg twice daily, in the morning and evening. If participants do not match to the discontinuation criteria, they can continue the same dose level therapy during Cycle 2 and subsequent cycles. (Each cycle will be 26 days.) arm 2: During Cycle 1, participants receive a single oral dose of vorinostat 200 mg on Day 1 in a fasted state; on Day 3 in a fed state; and on Day 19 in a fed state. On Days 5-18, participants receive vorinostat 200 mg twice daily, in the morning and evening. If participants do not match to the discontinuation criteria, they can continue the same dose level therapy during Cycle 2 and subsequent cycles. (Each cycle will be 26 days.) arm 3: During Cycle 1, participants receive a single oral dose of vorinostat 400 mg on Day 1 in a fasted state; on Day 3 in a fed state; and on Day 19 in a fed state. On Days 5-18, participants receive a single oral dose of vorinostat 400 mg once-daily in the morning. If participants do not match to the discontinuation criteria, they can continue the same dose level therapy during Cycle 2 and subsequent cycles. (Each cycle will be 26 days.) arm 4: During Cycle 1, participants receive a single oral dose of vorinostat 500 mg on Day 1 in a fasted state; on Day 3 in a fed state; and on Day 19 in a fed state. On Days 5-18, participants receive a single oral dose of vorinostat 500 mg once-daily in the morning. If participants do not match to the discontinuation criteria, they can continue the same dose level therapy on the Cycle 2 and subsequent cycles.(Each cycle will be 26 days.)
