ListOutcomeTime frameDescription
PrimaryOverall Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 by Investigator AssessmentUp to 24 months
Overall response rate (ORR) defined as the percentage of participants with a confirmed complete response (CR) or confirmed partial response (PR) via investigator assessment per RECIST (Response Evaluation Criteria In Solid Tumors Criteria) v1.1 relative to the total number of participants in the analysis population. Partial response is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Complete response is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<)10 millimeters (mm). Confidence intervals (CI) were calculated using the exact (Clopper-Pearson) method.
PrimaryBest Overall Response (BOR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 by Investigator AssessmentUp to 24 months
The Best Overall Response (BOR) with confirmation for a participant is defined as the best confirmed response (Confirmed Complete Response \[CR\] \> Confirmed Partial Response \[PR\] \> Stable Disease \[SD\] \> Progressive Disease \[PD\] \> Not Evaluable \[NE\]) from first T cell infusion until disease progression or initiation of new anti-cancer therapy, whichever is earlier, as assessed by the investigator per RECIST v1.1 Criteria.
SecondaryTime to Response (TTR) Assessed by InvestigatorUp to 24 months
Time to response was defined as the interval of time between the date of T-cell infusion and the first documented evidence of the confirmed response (PR or CR), in the subset of participants with a confirmed PR or CR as their best confirmed overall response. Partial response is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Complete response is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<)10 mm.
SecondaryDuration of Response (DOR) Assessed by InvestigatorUp to 24 months
Duration of response was defined as the interval between the initial date of confirmed response (PR/CR) and the date of progressive disease or death among participants with a confirmed response per RECIST 1.1. Partial response is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Complete response is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<)10 millimeters. Kaplan-Meier Median and 95% confidence intervals are presented. Confidence intervals were calculated using the Brookmeyer-Crowley method.
SecondaryProgression Free Survival (PFS) Assessed by InvestigatorUp to 24 months
Progression free survival was defined as the interval between the date of T cell infusion and the earliest date of disease progression or death due to any cause. Progressive disease (PD) is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. PFS based on responses assessed by investigator per RECIST v1.1 is presented. Kaplan-Meier Median and 95% confidence intervals are presented. Confidence intervals were calculated using the Brookmeyer-Crowley method.
SecondaryBest Overall Response (BOR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 by Independent Reviewer AssessmentUp to 24 months
The Best Overall Response (BOR) with confirmation for a participant is defined as the best confirmed response (Confirmed Complete Response \[CR\] \> Confirmed Partial Response \[PR\] \> Stable Disease \[SD\] \> Progressive Disease \[PD\] \> Not Evaluable \[NE\]) from first T cell infusion until disease progression or initiation of new anti-cancer therapy, whichever is earlier, as assessed by independent reviewer per RECIST v1.1 criteria.
SecondaryOverall Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 by Independent ReviewerUp to 24 months
Overall response rate (ORR) defined as the percentage of participants with a confirmed complete response (CR) or confirmed partial response (PR) via independent reviewer assessment per RECIST v1.1 relative to the total number of participants in the analysis population. Partial response is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Complete response is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<)10 millimeters (mm). Confidence intervals (CI) were calculated using the exact (Clopper-Pearson) method.
SecondaryTime to Response (TTR) Assessed by Independent ReviewerUp to 24 months
Time to response was defined as the interval of time between the date of T-cell infusion and the first documented evidence of the confirmed response (PR or CR), in the subset of participants with a confirmed PR or CR as their best confirmed overall response. Partial response is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Complete response is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<)10 mm.
