Design outcomes

Primary

MeasureTime frameDescription
Objective Response Rate (ORR)up to 733 daysORR was defined as the percentage of participants with a best overall response of complete response (CR) or partial response (PR), confirmed by ≥1 repeat assessment ≥28 days later, according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), as determined by the investigator. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 millimeters (mm). PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.

Secondary

MeasureTime frameDescription
Disease Control Rate (DCR)up to 733 daysDCR was defined as the percentage of participants with a best overall response of CR or PR, confirmed by ≥1 repeat assessment ≥28 days later, or stable disease (SD) for ≥12 weeks, by investigator assessment per RECIST v1.1. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. Progressive disease (PD): progression of a target or non-target lesion or presence of a new lesion. SD: no change in target lesions to qualify for CR, PR, or PD.
Duration of Response (DOR)up to 733 daysDOR was defined as the time from the earliest date of CR or PR, confirmed by ≥1 repeat assessment ≥28 days later, until the earliest date of disease progression by investigator assessment per RECIST v1.1, or death due to any cause, if occurring sooner than progression. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. PD: progression of a target or non-target lesion or presence of a new lesion.
Number of Participants With Any Treatment-emergent Adverse Event (TEAE)up to 823 daysAn adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. An AE could therefore have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug up to 90 days after the last dose of study drug or until the start of new anticancer therapy, whichever occurred first.
Number of Participants With Any ≥Grade 3 TEAEup to 823 daysA TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug up to 90 days after the last dose of study drug or until the start of new anticancer therapy, whichever occurred first. The severity of AEs was assessed using Common Terminology Criteria for Adverse Events version 5 (CTCAE v5) Grades 1 through 5. Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; treatment not indicated. Grade 2: moderate; minimal, local, or noninvasive treatment indicated; limiting age-appropriate activities of daily living. Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living. Grade 4: life-threatening consequences; urgent treatment indicated. Grade 5: fatal.

ORR was defined as the percentage of participants with a best overall response of complete response (CR) or partial response (PR), confirmed by ≥1 repeat assessment ≥28 days later, according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), as determined by the investigator. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 millimeters (mm). PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.

Time frame: up to 733 days

Population: Full Analysis Set: all study participants who received ≥1 dose of study drug. Participants were analyzed according to the treatment group/dose to which they were assigned. Confidence intervals were calculated using the Clopper-Pearson method.
