About
This is a two-stage, Phase II clinical trial for patients with relapsed or refractory Hodgkin Lymphoma. The purpose of stage I is to evaluate whether treatment with the study drug decitabine in combination with SHR-1210 is safe and more effective than treatment with SHR-1210 alone; and reverse the resistance of anti-PD-1 antibody in patients with HL who had previously treated with anti-PD-1 monotherapy. If it is deemed that the combination therapy is more efficacious than SHR-1210 monotherapy (The CR rate of the combination group is at least 30% higher compared to monotherapy group with a minimal follow-up of 6 months in predicting 60 subjects naïve to anti-PD-1 antibody who are randomly assigned (2:1) to the above two groups), the stage II study will be revised to a multicohort, decitabine-plus-SHR1210 single-arm clinical trial. The primary objective of stage II study is to evaluate the long-term response duration with decitabine-plus-SHR-1210 in relapsed or refractory Hodgkin Lymphoma.
