New hope for tough lymphomas: vorinostat shows promise in early trial
NCT ID NCT00875056
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a drug called vorinostat in 56 people with certain types of lymphoma (follicular, other indolent B-cell, or mantle cell) that had returned or stopped responding to prior treatments. The main goal was to see how many patients' tumors shrank or disappeared (response rate) and to check for side effects. The study was completed, and results help understand if vorinostat might be a useful option for these hard-to-treat lymphomas.
