cmoep in the treatment of untreated peripheral t-cell lymphoma

Conditions: Peripheral T-cell Lymphoma

Summary: this is a prospective, single arm, multicenter, dose-escalation clinical study to evaluate the safety and efficacy of cmoep in patients with untreated peripheral t-cell lymphoma.

this is a single arm, multicenter, dose-escalation study which mainly explores the dose limiting toxicity (dlt) of liposomal mitoxantrone hydrochloride in combination with cyclophosphamide, vincristine, etoposide and prednisone（cmoep） in patients with untreated peripheral t-cell lymphoma. liposomal mitoxantrone hydrochloride will be given on day 1 at three different doses (15 mg/m2, 18 mg/m2, 20 mg/m2) and be combined with cyclophosphamide, vincristine, etoposide and prednisone. the dose limited toxicity (dlt) will be evaluated after the first cycle of therapy. a maximum of 6 cycles of therapy are planned.
