Clinical Trial Summary

The study is being conducted to compare JS004 plus Toripalimab with Investigator-Selected Chemotherapy in Patients with PD-(L)1 monoclonal antibody refractory Classic Hodgkin Lymphoma (cHL)

Description:

The study is a randomized, open-label, phase III clinical trial. The main objective is to compare the efficacy of JS004 plus Toripalimab with Investigator-Selected Chemotherapy in treating patients with PD-(L)1 monoclonal antibody refractory Classic Hodgkin Lymphoma (cHL). The study will assess the safety and tolerability of JS004 combined with Toripalimab.

Intervention

Biological:
• JS004 in combination with Toripalimab
Participants will receive JS004 in combination with Toripalimab (200 mg/240 mg) by intravenous (IV) infusion on Day 1, then every three weeks (Q3W), for up to 35 infusions.

Drug:
• Bendamustine or gemcitabine
Participants will receive Investigator-Selected chemotherapy of EITHER bendamustine by IV infusion at a dose of 90 or 120 mg/m^2 on Day 1 and Day 2 of either a 3- or 4-week cycle for up to 6 cycles OR gemcitabine by IV infusion at a dose of 1000 mg/m^2 on Day 1 and Day 8 of a 3-week cycle for up to 6 cycles.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression Free Survival (PFS) per Lugano criteria 2014 as Assessed by Independent review committee (IRC)	PFS is defined as the time from randomization to the first documented disease progression per Lugano criteria 2014 as assessed by IRC or death due to any cause, whichever occurs first.	Up to approximately 36 months
Secondary	Overall Survival (OS)	OS is defined as the time from randomization to death due to any cause.	Up to approximately 45 months
Secondary	Progression Free Survival (PFS) per Lugano criteria 2014 Assessed by Investigator	PFS is defined as the time from randomization to the first documented disease progression per Lugano criteria 2014 assessed by Investigator or death due to any cause, whichever occurs first.	Up to approximately 36 months
Secondary	Objective Response Rate (ORR) per Lugano criteria 2014 Assessed by Investigator	ORR is defined as the percentage of participants who achieve a complete response (CR) or partial response (PR) per Lugano criteria 2014 assessed by Investigator	Up to approximately 36 months
Secondary	Complete response rate (CRR) per Lugano criteria 2014 Assessed by Investigator	Complete response rate (CRR) is defined as the proportion of subjects in which BoR is CR, best overall response (BoR) refers to the best response as determined by the investigator.	Up to approximately 36 months
Secondary	Duration of Response (DOR) per Lugano Response Criteria as Assessed by Investigator	For participants who demonstrate CR or PR per Lugano criteria 2014 as assessed by Investigator, DOR is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first.	Up to approximately 36 months
Secondary	Incidence and severity of all adverse events (AE) that occurred during the clinical trial	An AE is any untoward medical occurrence in a clinical study participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number and sverity of participants who experience an AE will be presented.	Up to approximately 36 months
Secondary	Pharmacokinetics	To characterize the trough concentrations of JS004 and toripalimab;	Up to approximately 36 months
Secondary	Immunogenicity profiles	To characterize incidence and titer of antidrug antibodies (ADA) and/or neutralizing antibodies (Nab);	Up to approximately 36 months
