ListOutcomeTime frameDescription
PrimaryProgression Free Survival (PFS) in Patients with PIK3CA WT and PIK3CA MT Breast CancerApproximately 48 months
PFS is defined as the time from randomization to death or the first documented progression, whichever occurs first, confirmed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria, as determined based on blinded independent central review (BICR)
SecondaryOverall Survival (OS) in Patients with PIK3CA WT and PIK3CA MT Breast CancerFrom date of randomization to the date of death due to any cause, up to approximately 48 months
OS is defined as the length of time from randomization until the date of death from any cause method, where PFS is defined as the time from randomization to death or the first documented progression, whichever occurs first, confirmed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria, as determined based on blinded independent central review (BICR)
SecondaryOverall Response Rate (ORR) in Patients with PIK3CA WT and PIK3CA MT Breast CancerUp to approximately 48 monthsPercentage of subjects who achieved an objective response according to RECIST v1.1 criteria (complete response \[CR\] or partial response \[PR\]) as assessed by BICR)
SecondaryDuration of Response (DOR) in Patients with PIK3CA WT and PIK3CA MT Breast CancerUp to approximately 48 monthsTime from the assessment of initial response (PR or better) to death or first documented disease progression as assessed by BICR, whichever occurs first
SecondaryTime to Response (TTR) in Patients with PIK3CA WT and PIK3CA MT Breast CancerUp to approximately 48 monthsTime form randomization to the first assessment of PR or better as assessed by BICR, whichever comes first
SecondaryClinical Benefit Rate (CBR) in Patients with PIK3CA WT and PIK3CA MT Breast CancerUp to approximately 48 monthsPercentage of subjects with CR, PR, or stable disease (SD) \>24 weeks as assessed by BICR
SecondaryQuality of Life (QOL)Functional Assessment of Cancer Therapy - Breast Trial Outcome Index (FACT-B TOI) Questions in Patients with PIK3CA WT and PIK3CA MT Breast CancerFrom baseline to 30 Day Safety Follow-up
The FACT-B TOI is an abbreviated (24-item) version of the full FACT-B which focuses only on the patient's Physical Well-being (PWB), Functional Well-being (FWB), and Breast Cancer Subscale (BCS) components using a 5-level scale, (Not at all, A little bit, Some-what, Quite a bit, Very much).
SecondaryQuality of Life (QOL) NCCN-FACT Breast Symptom Index -16 (NFBSI-16) in Patients with PIK3CA WT and PIK3CA MT Breast CancerFrom baseline to 30 Day Safety Follow-up
NCCN-FACT is derived from the FACT-B and only 4 additional items will be administered to enable optional scoring of the NFBSI subscales and total score using a 5-level scale (Not at all, A little bit, Some-what, Quite a bit, Very much).
SecondaryPatient-Reported Outcomes in Patients with PIK3CA WT and PIK3CA MT Breast CancerFrom baseline to 30 Day Safety Follow-up
Patient-Reported Outcomes Measurement Information System (PROMIS®) Short Form v2.0 - Physical Function 8c using a 5-level scale (Without any difficulty, With a little difficulty, With some difficulty, With much difficulty, Unable to do)
SecondaryEuroQol 5 in Patients with PIK3CA WT and PIK3CA MT Breast CancerFrom baseline to 30 Day Safety Follow-up
EuroQol 5 Dimension 5 Level (EQ-5D-5L) - This is a 5 question, self-administered visual analog scale (VAS) where patients use 0 (worst health) to 100 (best health) to indicate how they view their health.
SecondaryAdverse EventsUp to approximately 48 months
Safety and tolerability will be evaluated by review of type, incidence, severity (as graded by the National Cancer Institute Common Terminology Criteria for Adverse Events \[NCI CTCAE\] v5.0), seriousness, and relationship to study medications of adverse events (AEs) and any laboratory abnormalities
