About

This is a randomized, open-label, active controlled, multi-center, phase 3 clinical study to compare the efficacy and safety of Mitoxantrone Hydrochloride Liposome Injection with Chidamide in patients with relapsed/refractory Peripheral T Cell Lymphoma (PTCL).

Full description

This study is a randomized, open-label, positive control, multicenter, phase Ⅲ study to compare the efficacy and safety of Mitoxantrone Hydrochloride Liposome Injection with Chidamide in patients with relapsed/refractory Peripheral T Cell Lymphoma (PTCL). The eligible patients will be randomly assigned to the experimental and control groups in a 1:1 ratio. The patients in experimental group will receive Mitoxantrone Hydrochloride Liposome Injection (20 mg/m2) once every 28 days for a maximum of 6-8 cycles. Patients in the control group will be treated with Chidamide (30 mg) twice per week with 3-day intervals until disease progression. Patients in the control group who had confirmed disease progression will have the option to switch to the liposomal mitoxantrone hydrochloride treatment. Patients will receive treatment until the completion of 6-8 cycles of treatment (this applies only to the experiment group), disease progression, intolerable toxicity, death, loss to follow-up, withdrawal (patient's decision or investigator's decision), whichever comes first. All patients will have post-treatment follow-up for disease status until disease progression/recurrence, initiation of new antitumor therapy, or being lost to follow-up.

7. Subjects must provide a written pathology/histological diagnosis report during the screening period and must agree to provide a tumor tissue section or tumor/lymph node tissue specimen to be sent to the central laboratory.

8. Life expectancy ≥ 12 weeks;

9.

10. Eligible fertile patients (male and female) must agree to use an effective method of contraception (hormonal or barrier or abstinence) with their partners from the study initiation until at least 7 months after the last treatment; women of childbearing potential must have a negative serum pregnancy test within 14 days prior to enrollment.
