- Progression-Free Survival (PFS) [ Time Frame: From randomization to investigator-determined date of disease progression or death, assessed up to 24 months. ]PFS is defined as the time from randomization to the investigator-determined date of disease progression or death, whichever comes first, using Response Evaluation Criteria in Solid Tumors (RECIST v1.1).
- Overall Survival (OS) [ Time Frame: From randomization to date of death, assessed up to 66 months. ]OS is defined as the time from randomization to the date of death.
- Time to Next Treatment (TTNT) [ Time Frame: From last dose of CMB305 to initiation of new therapy, assessed up to 24 months. ]TTNT is defined as the time from randomization to the start of post-study treatment subsequent intervention: [TTNT = start date of subsequent intervention - randomization date + 1]. Subsequent intervention includes anticancer therapy, cancer-related surgery and local regional therapy. Participants who do not start any post-study treatment intervention will be censored at their last known date of being alive.
- Distant Metastasis Free Survival (DMFS) [ Time Frame: From randomization to investigator-determined date of disease progression or death, assessed up to 24 months. ]DMFS is defined as the time from randomization to evidence of a new distant metastasis not documented at time of randomization: [DMFS = a new distant metastasis documented date - randomization date + 1]. Participants who do not have any new distant metastasis will be censored at their last tumor assessment.
- Overall Response Rate (ORR) [ Time Frame: From randomization to investigator-determined date of disease progression, assessed up to 24 months. ]ORR defined by RECIST v1.1 will be summarized by the number and percent of subjects who achieve a complete response (CR) or partial response (PR) based on the investigator's assessment. ORR will be compared between treatment arms using a logistic regression.
- Number of Participants Who Experienced a Treatment-Emergent Adverse Event (TEAE) [ Time Frame: From randomization to investigator-determined date of disease progression or death, assessed up to approximately 2 months. ]Safety will be assessed primarily based on reported adverse events (AEs), Medical Events of Interest (MEOIs), laboratory values, and concomitant medications reported from initiation of treatment with CMB305 or placebo.
- Quality of Life (QoL): EuroQol 5-Dimension 5 Level (EQ-5D-5L) and EuroQol 5-Dimension Youth (EQ-5D-Y) Questionnaires [ Time Frame: From Day 1 up to 12 months ]QoL evaluated using the EQ-5D-5L for participants ≥18 years of age or using the EQ-5D-Y for participants 12 to <18 years of age. EQ-5D-5L descriptive system is comprised of 5 dimensions-mobility, self-care, usual activities, pain/discomfort & anxiety/depression. Each dimension has 5 levels: not at all (level 1), mild (level 2), moderate (level 3), severe (level 4), extreme/leading to incapacity (level 5), with highest level corresponding to worst outcome. Participants indicated their health state by choosing the appropriate level from each dimension. The 5 digit health states thus obtained for each dimension were then converted into a single median index value using the EQ-5D-5L crosswalk index value calculator as recommended by EuroQol group. In the EQ-VAS, participants recorded their health state on a scale ranging from 0 (worst imaginable health state) to 100 (best imaginable health state).
- Number of Participants Who Discontinued Study Treatment Due to an AE [ Time Frame: Up to approximately 2 months ]The number of all participants who discontinued study treatment due to an AE is presented.
