What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: max 24 months
ORR is defined as the percentage of participants who have a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters). Responses are according to RECIST 1.1 as assessed by investigator.
max 24 months

Time Frame: max 24 months
DOR is defined as the time from first documented complete or partial response until disease progression, death from any cause, or censoring at date of last tumor assessment.
max 24 months
Disease control rate (DCR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1
Time Frame: max 24 months
DCR is defined as the proportion of patients with complete response (CR), partial response (PR) and stable disease (SD)
max 24 months
Overall survival (OS) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1
Time Frame: max 42 months
OS is defined as the time from study treatment to the date of death of the subject, regardless of the cause of death
max 42 months
Time to Response (TTR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1
Time Frame: max 24 months
TTR is defined as the time from the start of treatment until the first objective observation of a response (either partial response, PR, or complete response, CR), provided that the response is subsequently confirmed
max 24 months
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0
Time Frame: max 42 months
An adverse event (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 percentage of participants who experience at least one AE will be reported
max 42 months
