A Proof-of-Concept Multicenter Trial Evaluating Response Adapted Combination of Nivolumab and Axatilimab in Patients With Relapsed/Refractory Classical Hodgkin Lymphoma

Description

The goal of this clinical trial is to study the combination of nivolumab and axatilimab in patients with relapsed/refractory classical Hodgkin Lymphoma. This study will mainly look at if the combination works as expected.This study is a phase II, proof-of concept, prospective, multi-center study of combination of nivolumab and Axatilimab (SNDX-6352) in subjects with relapsed/refractory classical Hodgkin lymphoma. Nine evaluable patients will be enrolled and receive Axatilimab 3mg/kg Q4 weeks in combination with nivolumab 480mg Q4 weeks. If more than one DLT is observed during the DLT period (first two cycles) in the first 6 patients, the study drug dose will be reduced to 2mg/kg and additional patients (up to 6 at 2mg/kg dose) may be included to the study. This could result in maximum 12 patients for the entire study. The combination of Nivolumab and Axatilimab will be continued until progression/toxicity or a maximum of 12 months of treatment. The investigators expect that in patients
