Tidsramme: From the first dose of study drug(s) to 30 days after the last dose; up to approximately 42 months
|
An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatments, whether considered related to study treatments or not. A serious AE (SAE) was any untoward medical occurrence that, at any dose - resulted in death, - was life threatening, - required hospitalization or prolongation of existing hospitalization, - resulted in disability/incapacity, - was a congenital anomaly/birth defect. |
From the first dose of study drug(s) to 30 days after the last dose; up to approximately 42 months
|
|
Objective Response Rate (ORR)
Tidsramme: Response was assessed every 6 weeks from cycle 1 day 1 for the first 36 weeks and then every 12 weeks thereafter; maximum time on study follow-up was 42months.
|
ORR is defined as the percentage of participants who had a best overall response of complete response or partial response per the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. |
Response was assessed every 6 weeks from cycle 1 day 1 for the first 36 weeks and then every 12 weeks thereafter; maximum time on study follow-up was 42months.
