Primary Outcome Measures
NameTimeMethod
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0.up to 2 years
Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS) according to RECIST version 1.1up to 2 years

Defined as the time from first dose to the date of death due to any cause.

Objective Response Rate (ORR) according to RECIST version 1.1up to 2 years

Defined as the proportion of subjects with confirmed complete response (CR) or partial response (PR); a confirmed response is a response that persists on repeat-imaging ≥4 weeks after initial documentation of response.

Duration of Response (DOR) according to RECIST version 1.1up to 2 years

Defined as time from date of first objective response (either CR or PR) to first documentation of radiographic disease progression or death due to any cause, whichever occurs first.

Disease Control Rate (DCR) according to RECIST version 1.1up to 2 years

Defined as the proportion of subjects who have achieved CR, PR, or stable disease (duration of stable disease should be ≥3 months).

Time to Response (TTR) according to RECIST version 1.1up to 2 years

Defined as the time from first dose to first documentation of objective response (either CR or PR).

Progression-Free Survival (PFS) according to RECIST version 1.1up to 2 years

Defined as the time from first dose to first documentation of radiographic disease progression or death due to any cause, whichever occurs first.

Peak Plasma Concentration (Cmax)up to 1 years
Time of maximum drug concentration in hours [Tmax]up to 1 years
Elimination half-life in hours [t1/2]up to 1 years
Clearance (CL)up to 1 years
Distribution Volume (Vd)up to 1 years
Area under theplasma concentration versus time curve (AUC)up to 1 years
Number of Participants With anti-drug antibody (ADA)up to 1 years
Number of Participants With Neutralizing Antibodies (NAbs)up to 1 years
