A Study of AK129 With or Without AK117 in PD(L)1-refractory Classic Hodgkin Lymphoma
- Registration Number
- NCT06642792
- Lead Sponsor
- Akeso
- Brief Summary
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 Measures
Name Time Method 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.
- Secondary Outcome Measures
Name Time Method Progression-free survival (PFS) Up to approximately 2 years The time from C1D1 until disease progression assessed by investigator or death due to any cause, whichever occurs first.
Overall survival (OS) Up to approximately 2 years The time from C1D1 until death due to any cause.
Maximum concentration (Cmax) Up to approximately 2 years The maximum concentration of the drug observed in the blood plasma after administration.
Time to maximum concentration (Tmax) Up to approximately 2 years The time taken to reach the maximum concentration (Cmax) of the drug in the blood plasma.
Area under the curve (AUC) Up to approximately 2 years The area under the plasma concentration versus time curve, which represents the total drug exposure over time.
Half-life (T1/2) Up to approximately 2 years The time required for the plasma concentration of the drug to decrease by half.
Anti-drug antibody (ADA) Up to approximately 2 years Number of subjects with detectable anti-drug antibodies.
Disease control rate (DCR) Up to approximately 2 years The proportion of subjects achieving complete response (CR) , partial response (PR) or stable disease (SD) assessed by investigator per Lugano 2014 criteria.
Time to response (TTR) Up to approximately 2 years The time from cycle 1 day 1(C1D1) to the first recorded response assessed by investigator per Lugano 2014 criteria.
Duration of response (DoR) Up to approximately 2 years The time from the first recorded response until disease progression assessed by investigator or death due to any cause, whichever occurs first.
