Belinostat in Relapsed or Refractory Peripheral T-Cell Lymphoma

This is an open-label, multicenter, single arm efficacy and safety study in participants with relapsed or refractory peripheral T-cell lymphoma, who have failed at least one prior systemic therapy. Approximately 120 participants will be enrolled. Participants will be treated with 1000 mg/m\^2 belinostat administered as a 30-minute IV infusion on Days 1-5 of every 3-week cycle until there is disease progression or unmanageable treatment-related toxicities. The primary study endpoint is objective response rate (ORR) based on the International Harmonization Project (IHP) revision International Working Group (IWG) criteria. Safety will be evaluated during the study and for 30 days after the last administration of study drug. Adverse events and laboratory studies will be graded according to National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) v. 3.0.
