Outcome Measures
Primary Outcome Measures
- Incidence of dose limiting toxicities (DLTs) in the dose escalation phase [first 21 days]
Number of participants with dose limiting toxicities
- Number of participants with adverse events [up to 4 years]
Patients will be assessed for incidence and severity of adverse events (AEs) according to NCI-CTCAE criteria
Secondary Outcome Measures
- Peak Plasma Concentration (Cmax) [up to 4 years]
Cmax of JAB-21822 will be measured by using plasma PK samples
- Area under plasma concentration versus time curve (AUC) [up to 4 years]
- Objective response rate ( ORR ) [up to 4 years]
ORR is defined as the proportion of participants with complete response or partial response (CR+PR) per RECIST v 1.1
- Duration of response ( DOR ) [up to 4 years]
DOR is defined as the time from the participant's initial objective response (CR or PR) to study drug therapy, to disease progression or death due to any cause, whichever occurs first.
- Disease Control Rate ( DCR ) [up to 4 years]
DCR is defined as percentage of participants with complete response (CR), partial response (PR), or stable disease(SD) per CTCAE v1.1
- Progression-free survival (PFS) [up to 4 years]
PFS is defined as the interval of time between the date of first treatment to the earliest date of disease progression per CTCAE v1.1 or death which occurs first
