MeasureTime frameDescription
Phase 1: Number of Participants With Treatment-emergent Adverse Events (TEAEs)up to 17.4 monthsAn 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, that occurred after a participant provided informed consent. Abnormal laboratory values or test results that occurred after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). A TEAE was defined as any adverse event either reported for the first time or the worsening of a pre-existing event after the first dose of study drug.
Phase 1: Number of Participants With a Grade 3 or Higher TEAEup to 17.4 monthsAn AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. A TEAE was defined as any adverse event either reported for the first time or the worsening of a pre-existing event after the first dose of study drug. The severity of AEs was assessed using Common Terminology Criteria for Adverse Events (CTCAE) v4.03. Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2: moderate; minimal, local, or noninvasive intervention 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 intervention indicated. Grade 5: death due to AE.
Phase 2: Objective Response Rate (ORR)up to 24 monthsORR was defined as the percentage of participants with a confirmed best overall response of complete response (CR) or partial response (PR), per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1), as determined by investigator assessment of radiographic disease assessments, recorded before and including the first event of progressive disease (PD). 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: complete disappearance or 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.

Outcome results

Primary

Phase 1: Number of Participants With a Grade 3 or Higher TEAE

An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. A TEAE was defined as any adverse event either reported for the first time or the worsening of a pre-existing event after the first dose of study drug. The severity of AEs was assessed using Common Terminology Criteria for Adverse Events (CTCAE) v4.03. Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2: moderate; minimal, local, or noninvasive intervention 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 intervention indicated. Grade 5: death due to AE.

Phase 1: Duration of Disease Control

Duration of disease control (CR, PR, and SD) was measured from the first report of SD or better until PD or death from any cause, if occurring sooner than progression, determined by investigator assessment of radiographic disease assessments 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: complete disappearance or 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. SD: no change in target lesions to qualify for CR, PR, or PD. PD: progression of a target or non-target lesion or presence of a new lesion.

Time frame: up to 15.4 months

Population: FAS. The confidence interval was calculated based on the exact method for binomial distributions. Only participants with a confirmed CR, PR, or SD were analyzed.

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: complete disappearance or 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.

A TEAE was defined as any adverse event either reported for the first time or the worsening of a pre-existing event after the first dose of study drug. The severity of AEs was assessed using CTCAE v4.03. Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2: moderate; minimal, local, or noninvasive intervention 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 intervention indicated. Grade 5: death due to AE.

Phase 2: Number of Participants With TEAEs

An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results that occurred after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). A TEAE was defined as any adverse event either reported for the first time or the worsening of a pre-existing event after the first dose of study drug.
