About this study

Official title: Double-Blind Placebo-Controlled Randomized Phase III Trial of Fulvestrant and Ipatasertib as Treatment for Advanced HER-2 Negative and Estrogen Receptor Positive (ER+) Breast Cancer Following Progression on First Line CDK 4/6 Inhibitor and Aromatase Inhibitor

The purpose of this study is to find out whether a new drug, Ipatasertib, can slow the growth of advanced breast cancer when added to standard therapy (Fulvestrant).

Read the detailed description

Patients enrolled in this study will receive either Ipatasertib plus Fulvestrant or placebo (a substance that looks like the study drug but does not have any active or medicinal ingredient) plus Fulvestant. The study will provide information about the ability of Ipatasertib plus Fulvestrant to control the cancer, the side effects and safety of the treatment, how patients feel while taking the treatment and associated costs.

What is being measured

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

  1. Number of Participants With Progression-free Survival (PFS) Using RECIST 1.1

    Progression-free survival (PFS) defined as time from randomization to disease progression or death from any cause, whichever occurs first. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

    Measured: 4 years

Secondary outcomes (2)
  1. To Compare the Two Treatment Arms With Respect to Investigator Assessed PFS (Per RECIST 1.1) in the PIK3CA/AKT1/PTEN Altered Cohort

    The PFS is tested in the PIK3CA/PTEN/AKT1 altered status subset under the same 0.05 significance level among the 111 subjects in the PIK3CA/PTEN/AKT1 altered status subset

    Measured: 4 years

  2. Commencement of Subsequent Line of Systemic Therapy or Death (TSST)

    Number of patients with commencement of subsequent line of systemic therapy or death between enrollment and the end of study

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ipatasertib and Fulvestrant in people with Breast Cancer, run by Canadian Cancer Trials Group at 39 sites in 3 countries.

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 21 inclusion and 12 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: under way, not looking for participants, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 39 sites in Canada, Australia, New Zealand. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Jan 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Progression-free Survival (PFS) Using RECIST 1.1 (time frame: 4 years). 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 13 Apr 2026.
