Primary outcomes

  1. Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 by Investigator's Assessment

    Time frame: Cohort 1: Up to 5.3 years; Cohort 2: Up to 3.4 years; Cohort 3: Up to 3.3 years; Cohort 4: Up to 2.5 years

    ORR was defined as the percentage of participants who had the best overall response of either complete response (CR) or partial response (PR). Responses are based on the investigator-assessed tumor response using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) criteria for each histologic cohort. CR: Disappearance of all target and non-target lesions; and normalization of tumor marker levels initially above upper limits of normal; PR: >30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. The ORR rate was calculated with a two-sided exact 95% CI using the Clopper-Pearson method. Percentages are rounded off.

Secondary outcomes

    Time frame: Cohort 1: Up to 5.3 years; Cohort 2: Up to 3.4 years; Cohort 3: Up to 3.3 years; Cohort 4: Up to 2.5 years

    ORR was defined as the percentage of participants who had the best overall response of either CR or PR. Responses are based on BICR assessment using RECIST 1.1 criteria for each histologic cohort. CR: Disappearance of all target and non-target lesions; and normalization of tumor marker levels initially above upper limits of normal; PR: >30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD. The ORR rate was calculated with a two-sided exact 95% CI using the Clopper-Pearson method.

Response are according to RECIST 1.1 by BICR for each histological cohort. CR: Disappearance of all target and non-target lesions; and normalization of tumor marker levels initially above upper limits of normal;PR: >30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD. Disease progression was defined as an increase of >20% in the sum of diameters of target lesions, taking as reference the smallest sum on study(this includes the baseline sum if that is the smallest on study). In addition, the sum must also demonstrate an absolute increase of more than 5 mm or the appearance of ≥ 1 new non-target lesions and/or unequivocal progression of existing non-target lesions. DOR was estimated using Kaplan-Meier estimate. The 95% CI was computed by Brookmeyer-Crowley method.

SD:Neither sufficient shrinkage for PR nor sufficient increase for PD, taking reference of smallest sum LD since treatment started or ≥ 1 non-target lesions with maintenance of tumor marker level above normal limits.PD: Increase of >20% in sum of diameters of target lesions, taking reference of smallest sum(this includes baseline sum if smallest on study), the sum must also demonstrate an absolute increase of more than 5 mm or of ≥ 1 new non-target lesions and/or unequivocal progression of existing non-target lesions. Two-sided CI was based on Clopper-Pearson method.

In addition, the sum must also demonstrate an absolute increase of more than 5 mm or the appearance ≥ 1 new non-target lesions and/or unequivocal progression of existing non-target lesions.
