Study Description
SPEAR is a non-interventional / observational, prospective, multicenter study planned to
be conducted across ~ 30 sites in India, among HR-positive and HER2-negative ABC/MBC
patients. This being a non-interventional study, no investigational drug or intervention
will be administered as a part of the study participation. All the therapeutic decisions,
as well as the type and timing of disease monitoring, laboratory tests or medical
procedures will be at the discretion of the treating physician and upon patient's
consent. No visits will be scheduled as a part of this non-interventional study, however,
data by visits for variables will be collected for all the enrolled patients. Overall, this study will have 2 parts (Part A and Part B). However, it is to be noted
that, these parts (Part A and Part B) are independent of each other and can run in
parallel. The purpose of the Part A of study is to determine the proportion of PIK3CA
mutation positive patients among the HR-positive and HER2-negative ABC/MBC diagnosed
patients in India. The Part B of the study aims to evaluate the clinical effectiveness
and tolerability of alpelisib plus fulvestrant among men, pre-menopausal women (ovarian
ablation) or post-menopausal women who are PIK3CA mutation positive patients with
HR-positive and HER2-negative ABC/MBC diagnosis among Indian population, in the
real-world setting.
Part A- This will involve enrolling of approximately 1200 patients (males,
post-menopausal women or pre-menopausal women who are receiving ovarian ablation) with a
documented diagnosis of HR-positive HER2-negative ABC/MBC. The data on PIK3CA mutation
status will be collected only for those patients who signs ICF for participation in the
study. Once, patient signs ICF, their samples will be sent for PIK3CA mutation status
testing, that will be performed at central laboratory and the results on mutation status
will be reported to the investigator.
Part B- This part aims to enroll approximately 200 patients who are PIK3CA mutation
positive. The patients enrolled into the Part B of the study can either be continued from
Part A of the study or be a direct enrollment into the Part B of the study. For the
patient's entering directly into Part B of the study, positive PIK3CA status should be
available prior to study entry. All the patients entering into part B of the study must
be alpelisib treatment naïve. The patients enrolled into Part B of the study, should have
already been planned to receive treatment with alpelisib plus fulvestrant, based on their
treating physician's discretion and upon patient's consent. The treatment decision by the
physician are to be made independent of the patient's inclusion in this observational
study. During the Part B of the study, data by visits for variables will be collected for
the enrolled patients at every 3 months interval (±1 month), if feasible or until a
maximum of 24 months observational period or lost to follow-up (End-of-study [EoS]
assessment will be performed), or death, or disease progression, whichever occurs first.

to curative therapy or metastatic) - for direct enrollment patients into Part B of
the study.
3. Patient with histologically and/or cytologically confirmed diagnosis of HR-positive
(ER+ and/or PgR+), as well as HER2-negative breast cancer by local laboratory (HER2-
by Immunohistochemistry [IHC], for borderline2+ Fluorescence In Situ Hybridization
[FISH]) - for direct enrollment patients into Part B of the study.
4. Participants with confirmed positive PIK3CA mutation status prior to study entry.
5. A separate signed ICF for Part B of the study must be obtained by all the patients,
prior to any data collection, irrespective of patients who are being enrolled from
Part A of the study or who are being enrolled directly into Part B of the study.
6. Physician decision to treat patients with alpelisib plus fulvestrant, according to
the prescribing label and the local practicing guidelines.
7. Patient should be alpelisib treatment naïve.
Exclusion Criteria:
PART A:
