A Study of Liposome-entrapped Mitoxantrone Hydrochloride Injection in Relapsed/Refractory Peripheral T-cell Lymphoma and NK/T-cell Lymphoma

Study Overview
=================
Brief Summary
-----------------
This is a single-arm, open, multi-center, phase II study to evaluate the efficacy and safety of Mitoxantrone Hydrochloride Liposome Injection in Relapsed or refractory peripheral t-cell and NK/T-cell lymphoma.

Detailed Description
-----------------
The dosage regimen of Liposome-entrapped Mitoxantrone is multi-cycle 20mg/m2 intravenous infusion. Every 4 weeks is a treatment cycle, with administration on the first day of each cycle. End-of-treatment visit will be made to the subjects within 4 weeks after the end of the last administration. Progression-free survival (PFS) follow-up will be conducted to the subjects in stable or improved condition after treatment and the subjects with early termination of treatment due to intolerance in Week 8 after the last administration of study drug, and thereafter once every 8 weeks until PD, death, withdrawal of informed consent form (ICF), starting another new treatment or end of the entire study (whichever occurs first). Meanwhile, overall survival (OS) follow-up will also be conducted to the subjects with PD and starting another new treatment once every 8 weeks until death, withdrawal of ICF or end of the entire study (whichever occurs first).

Subjects shall always practice contraception strictly in accordance with the labels of contraceptive drugs/devices and the instructions of the investigator. Effective contraception measures shall be defined as follows: i)Sex partner vasectomized is the sole sex partner of the female subject; ii)Use of IUDs with a failure rate of less than 1% per year iii)Double contraception, e.g. spermatocide plus male condom, female condom, diaphragm, cervical cap or intrauterine device. Male subjects: who shall have received the vasectomy, or agree to take effective contraception measures during the study period and within 30 days after the last administration. Subjects who are able to comply with the study procedures, restrictions and requirements as judged by the investigator.

According to the judgement of the investigators ,Those with any severe or uncontrolled systematic disease, systematic complication, other severe complicated diseases (e.g. hemophagocytic syndrome) or special tumor condition that might make the subjects unsuitable for entry into the study or might affect the compliance to the protocol or might cause significant interference with the correct evaluation of safety, toxicity and efficacy of the study drug.
