Details and patient eligibility

About

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.

  • Participant has at least one measurable lesion by computerized tomography (CT) scan which is defined by Cheson's 1999 criteria

  • Participant has received at least 1 but up to 4 prior chemotherapeutic regimens, the most recent therapy must have failed to induce a partial response, or there must be recurrence in case of the most recent therapy has shown complete response, or there must be relapse in case of the most recent therapy has shown partial response

  • Life expectancy of >4 months

56 participants in 3 patient groups

Follicular Lymphoma (FL)
Experimental group
Description:
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.
Treatment:
Drug: Vorinostat
Indolent non-FL B-NHL or MCL
Experimental group
Description:
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.
Treatment:
Drug: Vorinostat
Other Disease
Experimental group
Description:
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.
Treatment:
Drug: Vorinostat
