A Study of Escalating Doses of Romidepsin in Association With CHOP in the Treatment of Peripheral T-Cell Lymphomas

Study Overview
=================
Brief Summary
-----------------
This study is an open label, multicenter study with two phases: A dose escalation phase of Romidepsin administered IV at day 1 and 8 or at day 1 without day 8 in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP)administered every 3 weeks for 8 cycles in patients with T-cell lymphoma. An expansion phase in order to assess the safety and the efficacy of the association of the recommended dose of Romidepsin associated with CHOP in a population of patients with T-cell lymphoma.

Detailed Description
-----------------
The primary objective of the study is to determine the feasibility of the combination and the recommended dose (RD) of Romidepsin when administered in association with CHOP in a population of patients with newly diagnosed Peripheral T-cell lymphoma (PTCL) as measured by the toxicities during treatment. Secondary objectives: To assess the safety of the association Romidepsin and CHOP, To assess the efficacy of the association of Romidepsin and CHOP: response rate and complete response rate, progression-free survival, response duration and overall survival.
