GroupInterventionDescription
Vorinostat 500 mgvorinostatDuring 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.)
Vorinostat 100 mgvorinostatDuring 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.)
Vorinostat 200 mgvorinostatDuring 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.)
Vorinostat 400 mgvorinostatDuring 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.)
Primary Outcome Measures
NameTimeMethod
Number of Participants Who Experienced One or More Adverse EventsUp to approximately 4 years

An adverse event is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.

Number of Participants Who Discontinued Study Treatment Due to an Adverse EventUp to approximately 4 years

An adverse event is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.

Number of Participants With a Dose-Limiting Toxicity (DLT) During Cycle 1Up to 26 days

A DLT was defined as an event considered to be related to study treatment and included: 1) Grade 4 neutropenia refractory to treatments persisting more than 5 days; 2) Grade 3 or more severe neutropenic fever; 3) Grade 3 thrombocytopenia requiring blood transfusions or Grade 4 thrombocytopenia; 4) Grade 4 hemoglobin decrease; 5) Grade 3 or more severe non-hematological toxicities other than anorexia, nausea/vomiting, and fatigue. (For the diarrhea, it was defined as not to use the frequency for the grading. For the alanine aminotransferase \[ALT\]/aspartate aminotransferase \[AST\]), it was defined as the case of over 300 IU/L; 6) Grade 3 or more severe anorexia, nausea/vomiting, and fatigue refractory to treatments; and 7) compliance of the study drug, while administrating 14 consecutive days, was less than 50% due to the drug-related adverse experience.
