New study tracks gene mutations in breast cancer patients on alpelisib
NCT ID NCT05022342
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed observational study in India enrolled 595 people with HR-positive, HER2-negative advanced or metastatic breast cancer who were already taking alpelisib plus fulvestrant. Researchers looked for PIK3CA gene mutations in tumors and tracked how well the cancer responded to treatment. The goal was to better understand the link between these mutations and patient outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- alpelisib plus fulvestrant
- What this could lead to
- If successful, this could help doctors understand which patients with advanced breast cancer might benefit most from alpelisib treatment.
- What could go wrong
- This is an observational study, not a controlled trial, so it cannot prove cause and effect. Results may not apply to other populations.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: PART A: 1. Males (≥18 years of age), post-menopausal\* females or pre-menopausal\*\* females with ovarian ablation (as per physician decision). 2. Patients with confirmed diagnosis of ABC/MBC (locoregionally recurrent not amenable to curative therapy or metastatic) 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 \[FISH\]) 4. A separate signed patient ICF for Part A of the study must be obtained prior to any data collection and sample shipment to the central designated laboratory 5. Patient's tumor tissue (archival or fresh) is available to be sent to a central laboratory for PIK3CA testing. In case, tissue sample (archival or fresh) is not available or feasible, liquid biopsy may be allowed. PART B: 1. Males (≥18 years of age), post-menopausal\* females or pre-menopausal\*\* females with ovarian ablation (as per physician decision). 2. Patients with confirmed diagnosis of ABC/MBC (locoregionally recurrent not amenable 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: 1\. Prior or current enrollment in any interventional clinical trial for ABC/MBC. Part PART B: 1. Patients' who had prior or current exposure to alpelisib or had prior or current exposure to any other PIK3CA inhibitor should be excluded. 2. Known hypersensitivity to alpelisib or fulvestrant, or to any of the excipients of alpelisib or fulvestrant. 3. Participant with type I or uncontrolled type II diabetes mellitus (HbA1c \>7, \[as per ADA/ACP guidelines 2020\]). 4. Participant has a history of severe cutaneous reactions like Stevens-Johnson-Syndrome (SJS), Erythema Multiforme (EM), Toxic Epidermal Necrolysis (TEN), or Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). 5. Participant has documented pneumonitis/interstitial lung disease which is active and requiring treatment. 6. Participant with unresolved osteonecrosis of the jaw. 7. Participant reports history of acute pancreatitis within 1 year of screening or past medical history of chronic pancreatitis, major surgery, any relevant medical condition, gastrointestinal (GI) condition preventing absorption, Child Pugh score B or C etc.
