Chidamide Decitabine Plus Anti-PD-1 Antibody for Patients With R/R cHL Who Are Transplant-ineligible or Refused Transplant.

A Randomized, Open-label, Phase 2 Trial of Chidamide+Decitabine Plus Anti- PD-1 Antibody for Patients With R/R cHL Who Are Transplant-ineligible or Refused Transplant

The prognosis for patients with relapsed/refractory classical Hodgkin lymphoma (cHL) who refuse or are ineligible for transplant is poor. This open label, randomized, phase 2 study aims to evaluate the efficacy of Chidamide+Decitabine plus Anti-PD-1 Antibody and Brentuximab Vedotin plus Anti-PD-1 Antibody in transplant-ineligible or refused transplant diagnosedR/R cHL. The primary objective of the study is to evaluate progression-free survival.

Study Overview

• Status: Recruiting
• Conditions: Ineligible Or Refused Transplant Patients With Classical Hodgkin Lymphoma
• Intervention / Treatment: Drug: Chidamide; Decitabine; Anti-PD-1 Antibody; Drug: Brentuximab Vedotin, anti-PD-1 antibody.

Detailed Description

The prognosis of refractory or early-relapsed lymphoma is poor, and it is even worse for those who are not eligible or refuse transplantation. Although many salvage regimens have been developed, there is no standard of care. Preliminary clinical observations have shown that Chidamide +Decitabine plus Anti-PD-1 Antibody might be beneficial for these patients. Brentuximab Vedotin plus Anti-PD-1 Antibody is a standard regimen . This open-label, randomized, phase 2 study aims to evaluate the efficacy of Chidamide+Decitabine plus anti-PD-1 antibody and Brentuximab Vedotin plus Anti-PD-1 Antibody, in patients with classical Hodgkin lymphoma who are transplant-ineligible or refused transplant . The primary objective of the study is to evaluate the progression free survival.The key secondary end points are complete response rate, objective response rate and the safety.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Chidamide+Decitabine+ Anti-PD-1 Antibody; Chidamide is a novel and orally active benzamide class of HDAC inhibitor that selectively inhibits activity of HDAC1, 2, 3 and 10, which can Induce tumor-cell apoptosis, suppress cell proliferation and enhance immune surveillance. Decitabine is an investigational (experimental) drug that works by depleting DNA methyltransferase 1(DNMT1), which can increase tumor antigens and HLA expression, enhances antigen processing, promotes T cell infiltration, and boosts effector T cell function. Immune checkpoint inhibitors have emerged as effective therapies for many cancers by promoting the reactivation and restoring function of T cells.	Drug: Chidamide; Decitabine; Anti-PD-1 Antibody; Chidamide 10mg/day, day1-4; 20mg/day, day 8,11, 15, 18. Decitabine 10mg/day, day1-5. Physicians will decide which immune checkpoint inhibitors will be used during treatment.
Active Comparator: Standard of care; Brentuximab Vedotin+ anti-PD-1 antibody	Drug: Brentuximab Vedotin, anti-PD-1 antibody.; Brentuximab Vedotin 1.8mg/kg d1, anti-PD-1 antibody d1. Physicians will decide which immune checkpoint inhibitors will be used during treatment.
