A Study of PM8002 in Combination With Chemotherapy in Patients With SCLC

A Phase II Study to Evaluate Efficacy, Safety and Pharmacokinetics of PM8002 Injection in Combination With Paclitaxel Injection as Second Line Treatment for Small Cell Lung Cancer(SCLC)

PM8002 is a bispecific antibody targeting PD-L1 and VEGF. This study will evaluate the efficacy and safety of PM8002 in combination with paclitaxel as second line treatment for SCLC.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Treatment related adverse events (TRAEs)	The incidence and severity of TRAEs graded according to NCI-CTCAE v5.0	Up to 30 days after last treatment
Objective Response Rate	Objective response rate (ORR) is the proportion of subjects with complete response (CR) or partial response (PR), based on RECIST v1.1.	Up to approximately 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease control rate (DCR)	DCR is defined as the proportion of subjects with CR, PR, or stable disease(SD) based on RECIST v1.1.	Up to approximately 2 years
Duration of response (DoR)	DoR is defined as the duration from the first documentation of objective response to the first documented disease progression (based on RECIST v1.1) or death due to any cause, whichever occurs first.	Up to approximately 2 years
Progression free survival (PFS)	PFS is defined as the time from the start of treatment until the first documentation of disease progression or death due to any cause, whichever occurs first (based on RECIST v1.1).	Up to approximately 2 years
Overall survival (OS)	OS is the time from the date of first dosing date to death due to any cause.	Up to approximately 2 years
