Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: This was a retrospective, noninterventional cohort study

Who may be able to join

  • Had a curated record for advanced or metastatic breast cancer diagnosis.
  • Note: Diagnosis of a/mBC is based on a curated record of M stage=M1, Stage 4/4a/4b, presence of metastatic tumor, Stage 3b/3c or presence of secondary neoplasm.
  • Had patient activity documented in ConcertAI Patient 360 Breast Cancer database (defined as a record of a clinic visit, medication administration, vital test, or lab test) or death within 90 days after the advanced or metastatic breast cancer diagnosis date.
  • Had documented receipt of treatment with alpelisib plus fulvestrant on or after the advanced or metastatic diagnosis date.
  • Had documented receipt of treatment with fulvestrant before the index date (start date of the earliest alpelisib plus fulvestrant regimen). This included (neo) adjuvant therapies.
  • Age ≥18 years on the index date.

Who cannot join

  • Had documented hormone receptor-negative (defined as both estrogen receptor-negative and progesterone receptor-negative) or HER2-positive status any time prior to index date (but prioritizing results closest to index date, if there were conflicting results).
  • Patient had a clinical trial registration date (i.e., participated in a clinical trial) on or before the index date.
  • Patients with "negative" PIK3CA test before index date (in case of multiple tests, the one closer to the index date was used).

About this study

This was a non-interventional, retrospective cohort study of patients with HR+/HER2- aBC treated with alpelisib (ALP) plus fulvestrant (FUL) who have received fulvestrant in any prior line of therapy (LoT). This study utilized de-identified individual patient data from the United States (US) ConcertAI Patient360 Breast Cancer database, sourced from electronic health records (EHR) (i.e., secondary use of data). Patients were indexed at their start date of the earliest alpelisib plus fulvestrant regimen and followed until their death date or last confirmed activity date in the absence of an observed death.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall survival (OS)

    OS was defined as the length of time from the start date of the earliest alpelisib plus fulvestrant regimen to the date of death, or last confirmed activity date in the absence of an observed death event.

    Measured: Up to approximately 21 months

  2. Real-world progression-free survival (rwPFS)

    rwPFS was defined as the length of time from the start date of the earliest alpelisib plus fulvestrant regimen to the first documented progression or death date occurring at least 14 days after the index date, or last adequate tumor assessment date in the absence of an observed progression or death event.

    Measured: Up to approximately 21 months

  3. Line of treatment of ALP+FUL received

    Measured: Baseline

  4. Line of treatment number of index regimens stratified by index year

    Measured: Baseline

  5. Starting dose of alpelisib

    Measured: Baseline

  6. Number of prior regimens

    Measured: Baseline

  7. Prior fulvestrant treatment category

    Measured: Baseline

  8. Prior regimens of patients who received alpelisib plus fulvestrant as first-line treatment

    Measured: Baseline

  9. Number of prior fulvestrant regimens prior to alpelisib plus fulvestrant

    Measured: Baseline

  10. Percentage of patients with prior exposure to CDK4/6i in the adjuvant setting

    Measured: Baseline

  11. Percentage of patients with prior exposure to chemotherapy in the metastatic setting

    Measured: Baseline

  12. Time to treatment discontinuation

    Measured: Up to approximately 21 months

  13. First antineoplastic regimen received after discontinuation of the alpelisib plus fulvestrant regimen

    Measured: Up to approximately 21 months

Secondary outcomes (13)
  1. Overall survival (OS) in subgroups of patients according to the prior lines of treatment

    OS was defined as the length of time from the start date of the earliest alpelisib plus fulvestrant regimen to the date of death, or last confirmed activity date in the absence of an observed death event.

    Measured: Up to approximately 21 months

  2. Real-world progression-free survival (rwPFS) in subgroups of patients according to the prior lines of treatment

    rwPFS was defined as the length of time from the start date of the earliest alpelisib plus fulvestrant regimen to the first documented progression or death date occurring at least 14 days after the index date, or last adequate tumor assessment date in the absence of an observed progression or death event.

    Measured: Up to approximately 21 months

  3. Line of treatment of ALP+FUL received in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  4. Line of treatment number of index regimens stratified by index year in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  5. Starting dose of alpelisib in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  6. Number of prior regimens in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  7. Prior fulvestrant treatment category in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  8. Prior regimens of patients who received alpelisib plus fulvestrant as first-line treatment in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  9. Number of prior fulvestrant regimens prior to alpelisib plus fulvestrant in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  10. Percentage of patients with prior exposure to CDK4/6i in the adjuvant setting in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  11. Percentage of patients with prior exposure to chemotherapy in the metastatic setting in subgroups of patients according to the prior lines of treatment

    Measured: Baseline

  12. Time to treatment discontinuation in subgroups of patients according to the prior lines of treatment

Questions about this trial

What is this clinical trial studying?

An observational study of HR+/HER2- Advanced or Metastatic Breast Cancer, run by Novartis Pharmaceuticals at 1 site in Ireland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Ireland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall survival (OS) (time frame: Up to approximately 21 months). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2023.
