Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Objective Response Rate (ORR)
Tidsramme: Up to approximately 31 months
Objective response rate was defined as the percentage of participants with a complete response (CR) or a partial response (PR) on two consecutive tumor assessments ≥4 weeks apart, as determined by the investigators using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). CR was defined as disappearance of all lesions. PR was defined as ≥30% decrease in the sum of diameters of target lesions, in the absence of CR, new lesions, and unequivocal progression in non-target lesions.
Up to approximately 31 months

Tidsramme
Overall Survival (OS)
Tidsramme: Up to approximately 31 months
Overall survival was defined as the time from enrollment to death from any cause. The median for OS is Kaplan-Meier estimate. 95% CI for median was computed using the method of Brookmeyer and Crowley.
Up to approximately 31 months
Progression-Free Survival (PFS)
Tidsramme: Up to approximately 31 months
PFS was defined as the time from enrollment to the first occurrence of disease progression as determined by the investigator(s), using RECIST v1.1, or to death from any cause, whichever occurs first. Disease progression was defined as ≥20% increase in in the sum of diameters of target lesions, unequivocal progression in non-target lesions, and/or appearance of new lesions.
Up to approximately 31 months
Duration of Response (DOR)
Tidsramme: Up to approximately 22 months
DOR was defined as the time from the first occurrence of a documented, confirmed objective response to disease progression as determined by the investigator, using RECIST v1.1, or to death from any cause, whichever occurs first. Objective response was defined as a complete response (CR) or a partial response (PR) on two consecutive tumor assessments ≥4 weeks apart. CR was defined as disappearance of all lesions. PR was defined as ≥30% decrease in the sum of diameters of target lesions, in the absence of CR, new lesions, and unequivocal progression in non-target lesions. Disease progression was defined as ≥20% increase in the sum of diameters of target lesions, unequivocal progression in non-target lesions, and/or appearance of new lesions. Presented here is median DOR at the time of primary analysis. The median for the duration of response is Kaplan-Meier estimate. 95% CI for median was computed using the method of Brookmeyer and Crowley.
Up to approximately 22 months
Disease Control Rate (DCR)
Tidsramme: At 16 weeks
DCR was defined as the percentage of participants with a complete response (CR), a partial response (PR), or stable disease at 16 weeks as determined by the investigator using RECIST v1.1. CR was defined as disappearance of all lesions. PR was defined as ≥30% decrease in the sum of diameters of target lesions, in the absence of CR, new lesions, and unequivocal progression in non-target lesions. Stable disease was defined as neither sufficient shrinkage to qualify for CR or PR nor sufficient increase to qualify for disease progression. Disease progression was defined as ≥20% increase in the sum of diameters of target lesions, unequivocal progression in non-target lesions, and/or appearance of new lesions.
At 16 weeks
Number of Participants With Adverse Events
Tidsramme: Up to approximately 31 months
An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Up to approximately 31 months
Maximum Plasma Concentration (Cmax) of Cobimetinib
Tidsramme: Day 15 of Cycle 3 (cycle is 28 days): 2-4 hours after cobimetinib dose
Cmax is the maximum (or peak) concentration that a study drug achieves in the body.
Day 15 of Cycle 3 (cycle is 28 days): 2-4 hours after cobimetinib dose
Minimum Plasma Concentration (Cmin) of Cobimetinib
Tidsramme: Day 15 of Cycle 3 (cycle is 28 days): prior to cobimetinib dose
Cmin is the minimum (or trough) concentration that a study drug achieves in the body.
Day 15 of Cycle 3 (cycle is 28 days): prior to cobimetinib dose
Maximum Serum Concentration (Cmax) of Atezolizumab
Tidsramme: 30 minutes following end of atezolizumab infusion on Day 15 of Cycle 3 (each cycle is 28 days)
Cmax is the maximum (or peak) concentration that a study drug achieves in the body.
30 minutes following end of atezolizumab infusion on Day 15 of Cycle 3 (each cycle is 28 days)

Tidsramme: Prior to atezolizumab infusion on Day 1 of Cycles (each cycle is 28 days) 2, 4, 8, 12, and 16, Day 15 of Cycle 3
Cmin is the minimum (or trough) concentration that a study drug achieves in the body.
Prior to atezolizumab infusion on Day 1 of Cycles (each cycle is 28 days) 2, 4, 8, 12, and 16, Day 15 of Cycle 3
Number of Participants With Anti-drug Antibodies (ADAs)
Tidsramme: Day 1 of Cycles (each cycle is 28 days) 1, 2, 4, 8, 12, and 16; Day 15 of Cycle 3; at atezolizumab treatment discontinuation visit, and <90 days after last atezolizumab infusion (up to approximately 31 months)
Participants were considered to be ADA positive if they were missing data at baseline but developed an ADA response following study drug administration (treatment-induced ADA response), or if they were ADA positive at baseline and the titer of one or more post-baseline samples was at least 4-fold greater (i.e., ≥0.60-titer units) than the titer of the baseline sample (treatment-enhanced ADA response). Participants were considered to be ADA negative if they were missing data at baseline, had a post-baseline ADA result, and all post-baseline samples were negative, or if they were ADA positive at baseline but did not have any post-baseline samples with a titer that was at least 4-fold greater than the titer of the baseline sample (treatment unaffected).
Day 1 of Cycles (each cycle is 28 days) 1, 2, 4, 8, 12, and 16; Day 15 of Cycle 3; at atezolizumab treatment discontinuation visit, and <90 days after last atezolizumab infusion (up to approximately 31 months)
