Brief Summary

Primary Outcome Measures
NameTimeMethod
Progression Free Survival (2nd Line+ Population)Patients received treatment until PD by RECIST v1.1 criteria was met or until one of the treatment discontinuation or study withdrawal criteria was met.

To evaluate the efficacy of balixafortide + eribulin versus eribulin monotherapy on the primary endpoint of progression free survival (PFS). PFS, as assessed by the Independent Review Committee, defined as the time from the date of randomization to the earliest evidence of documented progressive disease or death from any cause. Patients who were alive without postbaseline assessments or without documented progressive disease, lost to follow-up, withdrew consent, started an anticancer therapy prior to observing a progressive disease or with an event documented after 2 or more missing tumor assessments were censored.

PFS was evaluated according to RECIST v1.1 guidelines for complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD).

Progression Free Survival (3rd Line+ Population)Patients received treatment until PD by RECIST v1.1 criteria was met or until one of the treatment discontinuation or study withdrawal criteria was met.

To evaluate the efficacy of balixafortide + eribulin versus eribulin monotherapy on the primary endpoint of progression free survival (PFS). PFS, as assessed by the Independent Review Committee, defined as the time from the date of randomization to the earliest evidence of documented progressive disease or death from any cause. Patients who were alive without postbaseline assessments or without documented progressive disease, lost to follow-up, withdrew consent, started an anticancer therapy prior to observing a progressive disease or with an event documented after 2 or more missing tumor assessments were censored.

PFS was evaluated according to RECIST v1.1 guidelines for complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD).

Secondary Outcome Measures
NameTimeMethod
Overall Survival (3rd Line+ Population)The Investigator monitored the patient for OS status every 6 months (or more frequently) until: death, the patient withdrew consent to follow-up for survival, or until the patient was lost to follow-up (whichever occurred first).

To compare the overall survival (OS) between patients in the balixafortide + eribulin treatment arm versus eribulin monotherapy treatment arm. OS is defined as the time from date of randomization to date of death due to any cause. Patients who are lost to follow-up or are not known to have died at the time of data-cut-off for analysis or who do not have any follow up since randomization were censored.
