Trial Outcomes & Findings for STAR Cape+BKM120 MBC With Brain Met (NCT NCT02000882)

NCT ID: NCT02000882

Last Updated: 2022-02-07

Results Overview

CBR in the patients following WBRT or SRS or both will be the primary endpoint and is calculated as the total number of responders (CR or PR, assessed by RECIST 1.1) plus stable disease greater than or equal to 24 weeks (CR + PR + SD ≥ 24 weeks) divided by the total number of evaluable patients. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

To assess ORR (CR + PR) associated with BKM120 plus capecitabine in the central nervous system based on local investigator assessment. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm.
