This is a phase I/II study. All subjects are patients diagnosed with relapse or refractory (R/R) classic Hodgkin lymphoma (cHL) and has progressed on treatment with PD-1/L1 inhibitor therapy. The purpose of this study is to evaluate the safety and efficacy of AK129 (bispecific antibody targeting LAG-3 and PD-1) monotherapy or in combination with AK117 (anti-CD47 monoclonal antibody) in R/R cHL with PD-1/L1 inhibitor treatment failure.

Primary outcome measure(s)
Phase I: Number of participants with dose limiting toxicity (DLT) — Within the first 28 days following the first dose of study treatment. Any untoward medical occurrence in a subject within the first 28 days following the first dose, considered related to the study treatment.
Phase I/II: Incidence and severity of adverse events (AEs) — Up to approximately 2 years. Any untoward medical occurrence in a subject, temporally associated with the use of study treatment, whether or not considered related to the study treatment.
Phase I/II: Objective response rate (ORR) — Up to approximately 2 years The proportion of subjects achieving complete response (CR) or partial response (PR) assessed by investigator per Lugano 2014 criteria.
