The purpose of the study was to assess efficacy, tolerability, safety and pharmacokinetics of Romidepsin in subjects with progressive or relapsed peripheral T-cell lymphoma
This is a Phase 1/2, non-randomized, open-label, single-arm trial with two phases. The first phase is a 3 + 3 dose escalation phase to determine a recommended dose for treating patients with Peripheral T-Cell Lymphoma (PTCL) or Cutaneous T-Cell Lymphoma (CTCL) based on the assessment of Dose Limiting Toxicities (DLTs).The second phase will assess efficacy at the recommended dose by measuring objective response \[Complete Response (CR), Unconfirmed Complete Response (CR(u)) or Partial Response (PR)\] and determining best overall response of each patient. Phase 1 will enroll a maximum of 12 patients and Phase 2 will enroll up to approximately 40 patients

Participants With Treatment-Emergent Adverse Events (TEAEs) Associated With Romidepsin
An adverse event (AE) is any noxious, unintended, or untoward medical occurrence that may appear or worsen during the course of a study. An AE that resulted in any of the outcomes was defined as a serious (SAE): • Death • Life-threatening event • An inpatient hospitalization or prolongation of existing hospitalization • Persistent or significant disability or incapacity; • Congenital anomaly or birth defect • Other important medical event The investigator judged the relationship of an AE to study drug based on the timing of the AE relative to drug administration and whether or not other drugs, therapeutic interventions, or underlying conditions could provide an explanation for the event. The severity of an AE was evaluated by the investigator according to Common Terminology Criteria for Adverse Events (CTCAE Version 3.0), Japanese Clinical Oncology Group (JCOG) where Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Life-threatening and Grade 5 = Death.
