Conditions

Classic Hodgkin Lymphoma

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.

Interventions

DRUGAK129

Subjects receive AK129 intravenously.

DRUGAK117

Subjects receive AK117 intravenously.

Design outcomes

Primary

MeasureTime frameDescription
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 yearsThe proportion of subjects achieving complete response (CR) or partial response (PR) assessed by investigator per Lugano 2014 criteria.

Secondary

MeasureTime frameDescription
Progression-free survival (PFS)Up to approximately 2 yearsThe 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 yearsThe time from C1D1 until death due to any cause.
Maximum concentration (Cmax)Up to approximately 2 yearsThe maximum concentration of the drug observed in the blood plasma after administration.
Disease control rate (DCR)Up to approximately 2 yearsThe proportion of subjects achieving complete response (CR) , partial response (PR) or stable disease (SD) assessed by investigator per Lugano 2014 criteria.
Area under the curve (AUC)Up to approximately 2 yearsThe area under the plasma concentration versus time curve, which represents the total drug exposure over time.
Half-life (T1/2)Up to approximately 2 yearsThe time required for the plasma concentration of the drug to decrease by half.
Anti-drug antibody (ADA)Up to approximately 2 yearsNumber of subjects with detectable anti-drug antibodies.
Time to maximum concentration (Tmax)Up to approximately 2 yearsThe time taken to reach the maximum concentration (Cmax) of the drug in the blood plasma.
Time to response (TTR)Up to approximately 2 yearsThe 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 yearsThe time from the first recorded response until disease progression assessed by investigator or death due to any cause, whichever occurs first.
