Study summary

The goal of this study is to test whether monitoring insulin levels and using pioglitazone to treat hyperglycemia and hyperinsulinemia in patients treated with Alpelisib for metastatic breast cancer is feasible and safe, and to assess the rates of glycemic control, dose reductions and treatment discontinuation and the progression free survival of patients treated with this regimen.

Read the detailed description
  1. To assess the feasibility and safety of monitoring insulin levels alongside glucose levels and of directing antidiabetic treatment according to insulin and fasting glucose levels in patients treated with Alpelisib for metastatic breast cancer.
  2. To assess the feasibility and safety of treatment with pioglitazone in these patients.
  3. To assess the rate of severe (grade 3-4) hyperglycemia in patients treated according to this protocol.
  4. To assess the rates of dose reductions and treatment discontinuation due to hyperglycemia in patients treated according to this protocol.
  5. To assess the median progression free survival of patients treated according to this protocol

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with ER positive negative breast cancer, harboring an activating PIK3CA mutation, scheduled to start treatment with Alpelisib and fulvestrant.
  • Ages 18 - 85
  • performance status 0, 1 or 2
  • Ability to understand and willingness to sign a written .

Exclusion criteria

Exclusion Criteria:

  • Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of Alpelisib
  • Uncontrolled diabetes mellitus, defined as above 8%
  • Diabetes mellitus controlled by insulin
  • Uncontrolled intercurrent illness including, but not limited to: active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnancy
  • Known allergy to pioglitazone
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2022 (actual). Primary completion is estimated for Dec 2026, 48 months after the start.

Of 371 non-industry phase 1 interventional studies under Breast Neoplasms, half reached primary completion within 48 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 77. This study's planned 48 months is close to that.

Counting every sponsor, half of 759 studies reached it within 44 months; a quarter within 25 and three quarters within 66.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 3, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
