PRIMARY outcome

Timeframe: Every 6 weeks from randomization during the first 9 months and thereafter, every 9 weeks up to 20 months

Population: Efficacy population included all participants randomly assigned to either treatment arm with externally confirmed pathological and molecular diagnosis of translocation-related sarcomas (TRS)

The PFS was assessed as median number of days from the date of randomization until the first documented sign of disease progression (increase in disease; radiographic, clinical, or both) or death due to any cause, whichever occurred earlier.

Progression - Free Survival (PFS)
19.6 months
Interval 5.7 to 32.3
8.3 months
Interval 7.1 to 25.0

SECONDARY outcome

Timeframe: 6 months

Population: Efficacy population included all participants randomly assigned to either treatment arm with externally confirmed pathological and molecular diagnosis of TRS.

Percentage of participants survived for 6 months from the start of study treatment without progression of disease. Progression of the disease was associated with increasing symptoms, including pain from new or progressing lesions. Delay in disease progression generally represents a clinical benefit to the participant.

SECONDARY outcome

Timeframe: Every 6 weeks during first 9 months of the study and thereafter every 9 weeks up to 20 months

Population: Efficacy population included all participants randomly assigned to either treatment arm with externally confirmed pathological and molecular diagnosis of TRS.

Tumor response was assessed according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria: Partial Response (PR)=at least 30% reduction in the sum of the longest dimensions (LD) of all target lesions in reference to the baseline sum LD, Complete Response (CR) =Disappearance of all non-target lesions. Percentage of participants with objective tumor response was determined by the number of participants with PR or CR divided by the total number of response-evaluable participants.

Timeframe: Baseline up to End of Study (an average of 4 years)

Overall survival defined as time from the date of randomization to the date of death. For participants who were alive at the time of analysis, overall survival was censored at the last contact date.

Upper limit of confidence interval was not reached because of high censorship rate that is smaller number of events.

SECONDARY outcome

Timeframe: Up to 20 months

Population: Efficacy population included all participants randomly assigned to either treatment arm with externally confirmed pathological and molecular diagnosis of TRS. 'N' (number of participants analyzed) signifies participants who were evaluable for this outcome measure.

The DOR is defined as the time from date of first documentation of response (CR or PR, whichever comes first) to the date of documented PD or death. PR=at least 30% reduction in the sum of the longest dimensions (LD) of all target lesions in reference to the baseline sum LD, CR =Disappearance of all non-target lesions.
