Plain-language summary
This is a multi-center, two-cohorts, phase IIIb study of Capivasertib+Fulvestrant in HR+/HER2-ABC who had disease recurrence/progression following 1-2L endocrine therapy.
The Primary objective is to assess the efficacy of capi+ful by assessment of TFST (Time to first subsequent treatment) of PIK3CA/AKT1/PTEN-altered subgroup in cohort1.

Inclusion criteria
. Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the clinical study protocol (CSP).
. Provision of signed and dated, written ICF prior to any mandatory study specific procedures, sampling, and analyses.
. Patients must be aged ≥18 years at the time of signing the ICF
. Adult females, pre- and/or post-menopausal, and adult males -Pre-menopausal (and peri-menopausal i.e., those that do not meet the criteria for post-menopausal defined below) women can be enrolled if amenable to treatment with an LHRH agonist. Patients are to have commenced concomitant treatment with LHRH agonist prior to or on Cycle 1, Day 1 and must be willing to continue on it for the duration of the study -Post-menopausal women are defined as: a)aged ≥60 years of age, or b)aged \<60 years of age and amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments/chemotherapy/ovarian suppression/tamoxifen or similar. These patients should also have serum oestradiol and follicle stimulating hormone (FSH) levels confirmed as being within the standard laboratory reference range for post-menopausal females, or c)documented bilateral oophorectomy
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Time to first subsequent treatment (TFST) of PIK3CA/AKT1/PTEN-altered population in Cohort 1
Timeframe: From the first dose of study intervention to the earlier of start date of the first subsequent therapy after discontinuation of study intervention, or death in PIK3CA/AKT1/PTEN-altered population in Cohort 1, up to approximately 2 years
. Histologically confirmed HR+/HER2- breast cancer determined from the most recent tumour sample (primary or metastatic), as per the American Society of Clinical Oncology and College of American Pathologists guideline recommendations. To fulfil the requirement of HR+ disease, a breast cancer must express ER with or without co-expression of progesterone receptor. 1)ER+ defined as ≥1% of tumour cells stain positive for ER on immunohistochemistry (IHC) or, if no percentage is available, then an Allred IHC score of ≥3/8, 2)Progesterone receptor positive defined as ≥1% of tumour cells stain positive for progesterone receptor on IHC or, if no percentage is available, then an Allred IHC score of ≥3/8; or progesterone receptor negative defined as \<1% of tumour cells stain positive for progesterone receptor on IHC or, if no percentage is available, then an Allred IHC score of ≤2/8; or progesterone receptor unknown, 3)or the investigator assesses the condition as HR+ status and 4)HER2- defined as 0 or 1+ intensity on IHC, or 2+ intensity on IHC and no evidence of amplification on in situ hybridisation (ISH), or if IHC not done, no evidence of amplification on ISH.
. Patients must have at least 1 measurable lesion.
. Patients must be eligible for fulvestrant therapy as per local investigator assessment.
. Consent to submit and provide a mandatory FFPE tumour sample for central testing.
Exclusion criteria
. A disease burden that makes the patient ineligible for endocrine therapy per the investigator's best judgement (e.g., symptomatic visceral disease that is potentially life-threatening in the short-term)
. History of another primary malignancy except for malignancy treated with curative intent with no known active disease ≥2 years before the first dose of study intervention and of low potential risk for recurrence. Exceptions include adequately resected non-melanoma skin cancer and curatively treated in situ disease. Radiotherapy within 2 weeks prior to the first dose of study intervention. Major surgery (excluding placement of vascular access) within 4 weeks prior to study treatment initiation
. With the exception of alopecia, any unresolved toxicities from prior therapy greater than CTCAE grade 1 at the time of starting study treatment
. Spinal cord compression or brain metastases unless asymptomatic, treated and stable and not requiring steroids within 4 weeks prior to study treatment initiation
. Leptomeningeal metastase
. Active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice).
. Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease
. Any of the following cardiac criteria: a)Mean resting QT interval corrected by Fridericia's formula (QTcF) \>470 msec obtained from 3 consecutive ECGs b)History of QT prolongation associated with other medications that required discontinuation of that medication. - Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g., complete left bundle branch block, third degree heart block) c)Medical history significant for arrhythmia (e.g., multifocal premature ventricular contractions, bigeminy, trigeminy, ventricular tachycardia), which is symptomatic or requires treatment (CTCAE Grade 3), symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia. Participants with atrial fibrillation controlled by medication or arrhythmias controlled by pacemakers may be permitted to enter the study based on the Investigator judgement with cardiologist consultation recommended. d)Any factors that increase the risk of corrected QT interval (QTc) prolongation or risk of arrhythmic events such as heart failure, clinically significant electrolyte abnormalities including hypokalaemia, hypomagnesaemia, and hypocalcaemia, potential for Torsades de pointes, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age or any concomitant medication known to prolong the QT interval e)Experience of any of the following procedures or conditions in the preceding 6 months: coronary artery bypass graft, angioplasty, myocardial infarction, unstable angina pectoris, f)Congestive heart failure New York Heart Association (NYHA) grade ≥2
