Primary Outcome Measures
NameTimeMethod
Efficacy: Overall Response Rate (ORR)2.5 years

ORR is defined as the proportion of complete responses or partial responses as assessed by RECIST v1.1

Secondary Outcome Measures
NameTimeMethod
Best overall response (BOR)2.5 years

BOR defined as the best response recorded from the date of T cell infusion until disease progression.

Time to response (TTR)2.5 years

TTR defined as the duration between T cell infusion and the initial date of the confirmed response.

Duration of response (DoR)2.5 years

DoR defined as the duration from the initial date of the confirmed response to the date of PD (or death).

Duration of stable disease (DoSD)2.5 years

DoSD defined as the duration from the date of T cell infusion to the date of PD (or death).

Progression- free survival (PFS)2.5 years

PFS defined as the interval between the date T cell infusion and the earliest date of disease progression based on RECIST v1.1 or death due to any cause.

Overall survival (OS)2.5 years

OS defined the duration between T cell infusion and death due to any cause.

To evaluate the safety and tolerability of ADP-A2M4 with pembrolizumab by determining incidence of Adverse events (AEs) including serious adverse events (SAEs)2.5 years

Determination of incidence, severity and duration of adverse events through assessment of adverse events including SAEs. Adverse events will be collected and graded as per Common Terminology Criteria for Adverse Events (CTCAE) version 5.0

To evaluate the safety and tolerability of ADP-A2M4 with pembrolizumab by determining the incidence, severity and duration of the AEs of special interest2.5 years

Adverse events of special interest will be listed along with duration and toxicity grade.
