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

Phase 2

Recruiting

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

• Registration Number: NCT06393361
• Lead Sponsor: Chinese PLA General Hospital

Brief Summary

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.

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.

Arm && Interventions

Group	Intervention	Description
Chidamide+Decitabine+ Anti-PD-1 Antibody	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.
Standard of care	Brentuximab Vedotin, anti-PD-1 antibody.	Brentuximab Vedotin+ anti-PD-1 antibody

Primary Outcome Measures

Name	Time	Method
1-year progression-free survival (PFS) rate	12 months	The proportion of patients who do not documented disease progression or death for a year from the date of first administration of the study drug.

Secondary Outcome Measures

Name	Time	Method
Complete response rate (CRR)	12 months	CRR assess by investigators per the 2014 Lugano classification rate of subjects achieved complete response in all evaluable subjects
Number of Subjects with treatment-related adverse events (AEs)	12 months	Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0.
Objective response rate (ORR)	12 months	The percentage of patients with CR or PR was determined according to the revised lymphoma efficacy evaluation criteria (Lugano 2014 criteria).
