A Phase II Study of the Combination of Azacitidine and Pembrolizumab for Patients Relapsed/Refractory Hodgkin's Lymphoma

Phase 2

Recruiting

• Conditions: Hodgkin's Lymphoma
• Interventions: Drug: Azacytidine; Drug: Pembrolizumab

• Registration Number: NCT05355051
• Lead Sponsor: M.D. Anderson Cancer Center

Brief Summary

This study is a Phase II single-center clinical trial designed to assess the efficacy, safety, and tolerability of pembrolizumab in combination with the 7-day regimen of azacitidine for the treatment of relapsed/refractory HL.

Detailed Description

OBJECTIVES:

Primary Objectives:

• To assess the overall response rate (ORR) of Pembrolizumab in combination with azacitidine in patients with relapsed or progressed classical Hodgkin lymphoma (HL).

Secondary Objectives:

* To assess the duration of response (DOR), relapse-free survival (RFS), and overall survival (OS) of patients with refractory/relapsed HL treated with this combination.

* To assess the safety of Pembrolizumab in combination with azacitidine in children with refractory/relapsed HL.

* To assess the proportion of patients who proceed to stem cell transplantation upon achieving response with the combination of Pembrolizumab and Azacitidine regimen.
