PFS was defined as the time from the date of randomization to the date of first documentation of progressive disease (PD) or death due to any cause, whichever occurred first. Per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, PD was defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.
An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. This includes any newly occurring event, or a previous condition that has increased in severity or frequency since the administration of study drug. A SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect or is a medically important event. Relationship of each AE to study drug will be determined by the Investigator.
CBR-16 was defined as the percentage of participants who achieved confirmed complete response (CR) or partial response (PR) of any duration or had confirmed stable disease (SD) as best response and the first 2 or more post baseline scans had PR/SD and the duration of SD was \>112 days. Disease response was assessed for target lesions by computed tomography (CT) or magnetic resonance imaging (MRI) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 guidelines. CR is disappearance of all target lesions. PR is \>=30% decrease in the sum of the longest diameter of target lesions. SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression (PD).
The mean changes of QTcI from time-matched baseline was measured by electrocardiogram (ECG) to evaluate the potential effect of drug on QTc interval duration. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measures mixed effects linear model. A negative change from baseline indicates shortening and a positive change from baseline indicates prolongation of QTcI interval.
