Brief Summary

The purpose of this study is to evaluate the safety, tolerability, and efficacy of vorinostat (MK-0683) in participants with relapsed and/or refractory follicular lymphoma. The exploratory purpose of this study is to evaluate efficacy of MK-0683 in participants with relapsed/refractory non-FL indolent B-NHL or relapsed/refractory MCL. The primary hypothesis is that MK-0683 will show efficacy in relapsed/refractory FL patients as measured by the Overall Response Rate.

Outcome Measures

Primary Outcomes (3)

• Objective Response Rate (ORR)

  ORR was defined as the percentage of participants who had a Complete Response (CR: Normal liver/spleen physical exam, all lymph nodes and nodal masses are normal, and there is no bone marrow involvement), a Complete Response/unconfirmed (CRu: Normal liver/spleen physical exam, plus at least a 75% decrease in the sum of the products of the greatest diameters of nodal masses if any are greater than 1.5 cm in their greatest diameter, normal or indeterminate bone marrow involvement), or a Partial Response (PR: Either normal physical exam, lymph nodes, and lymph node masses plus positive bone marrow involvement; OR normal physical exam or decrease in liver/spleen size plus at least a 50% decrease in the diameters of lymph nodes and nodal masses) as assessed using the international working group Non-Hodgkin's lymphoma standardized response criteria described by Cheson, BD in 1999. The percentage of participants who experienced a CR, CRu, or PR is presented.

  Up to 650 days

• Number of Participants Who Experienced an Adverse Event (AE)

  An AE was defined as any untoward medical occurrence in a participant administered study treatment and which did not necessarily have to have a causal relationship with this treatment. The number of participants who experienced an AE was presented.

  Up to approximately 29 months

• Number of Participants Who Discontinued Study Drug Due to Experiencing an Adverse Event (AE)

  An adverse event (AE) was defined as any untoward medical occurrence in a participant administered study treatment and which did not necessarily have to have a causal relationship with this treatment. The number of participants who discontinued from study drug due to an adverse event was reported.

  Up to 536 days

Secondary Outcomes (2)

• Time to Treatment Failure for Relapsed/Refractory FL

  Up to 650 days

• Time to Response for Relapsed/Refractory FL

  Up to 650 days

Study Arms (3)

Follicular Lymphoma (FL)

EXPERIMENTAL

Participants with relapsed/refractory FL received 200 mg of vorinostat (MK-0683) twice daily (200 mg x 2/day) for 14 consecutive days followed by 1 week (7 days) rest in a 21-day cycle, until they met the per-participant discontinuation criteria specified by the protocol.

Drug: Vorinostat

Indolent non-FL B-NHL or MCL

EXPERIMENTAL

Participants with indolent non-follicular lymphoma (FL) B-cell non-Hodgkin's lymphoma (B-NHL), or with mantle cell Lymphoma (MCL) received 200 mg of vorinostat (MK-0683) twice daily (200 mg x 2/day) for 14 consecutive days followed by 1 week (7 days) rest in a 21-day cycle, until they met the per-participant discontinuation criteria specified by the protocol.

Drug: Vorinostat

Other Disease

EXPERIMENTAL

Participants with disease other than relapsed/refractory follicular lymphoma (FL), non-FL B-cell non-Hodgkin's lymphoma (B-NHL), or mantle cell Lymphoma (MCL), as assessed by the Independent Central Pathological Committee, received 200 mg of vorinostat (MK-0683) twice daily (200 mg x 2/day) for 14 consecutive days followed by 1 week (7 days) rest in a 21-day cycle, until they met the per-participant discontinuation criteria specified by the protocol. This group was created to include participants who enrolled, but whose later diagnoses by the Independent Central Pathological Committee excluded them from analysis in the FL and non-FL B-NHL/MCL groups because they had different disease than those prespecified in the protocol.

Drug: Vorinostat

Interventions

Vorinostat DRUG

Two 100 mg oral capsules of vorinostat, twice daily (400 mg/day), on Days 1 through 14 of each 21 day cycle
