Plain English summary of protocol
Background and study aims
The study aims to evaluate the effectiveness of anticancer treatments by monitoring the number of cancer cells left in the body after treatment.
Who can participate?
Patients aged ≥18 years with early-stage HR-positive/HER2-negative breast cancer at high risk of relapse but with no evidence that the cancer has spread
What does the study involve?
Patients will first enter a surveillance phase. Blood will be collected periodically to monitor the absence or presence of circulating tumour DNA (ctDNA) in the bloodstream whilst participants continue to take ET as prescribed. If the ctDNA result turns positive, then patients will be screened to enter the treatment phase. The number of visits is between 7-14 over about 1-5 years. Blood samples will be taken every 3 months during the first year and every 6 months from the second year. Upon confirmed positive ctDNA, the participant will be allocated to one of four treatment arms. This can include either the control arm where participants will continue taking the same ET as previously prescribed or a medication called giredestrant, either as monotherapy (on its own) or in combination with abemaciclib or inavolisib. Apart from abemaciclib, the study drugs are not yet approved by the MHRA. In preclinical studies, giredestrant and inavolisib showed strong anti-tumour activity. Participants will receive study treatment every day from Day 1, continuously in cycles of 28 days for 2-5 years. Participants may continue to receive study drugs for a prolonged period. Once the treatment is complete, participants will have a safety follow-up visits. The following study procedures will be performed during the treatment phase: physical examinations, ECGs, blood tests, urine tests, CT/MRI/bone scans, ultrasound, and mammogram.
What are the possible benefits and risks of participating?
All risks and burdens will be discussed in detail with each participant during the informed consent process and will be stipulated in the participant information sheet. Opportunities to discuss and address it further will be offered throughout the trial. An independent committee of experts will review the continued safety of the study drugs and will swiftly act on any concerns.
Giredestrant and inavolisib are experimental medications; therefore, the risks and discomforts related to these drugs are not known, and there may be side effects no one knows about yet. Abemaciclib is a registered medication with marketing authorisation, but not all the side effects of abemaciclib when used alone or when given with other drugs are known. Participants will be monitored carefully. Abemaciclib treatment may be temporarily interrupted in patients who experience toxicity considered related to the study drug. In the event of multiple toxicities, dose interruption should be based on the worst toxicity observed. To date, available information from these studies has suggested that giredestrant does not cause serious side effects. Safety information for giredestrant is still limited at this time, and unforeseen risks may occur. Participants will be given medicines to help lessen the main side effects and encouraged to contact their medical doctor immediately for any observed side effects. Some side effects may be serious and may even result in death.
Based on the anti-estrogenic pharmacological activity of giredestrant, administration of giredestrant during pregnancy is expected to have an adverse effect and poses a risk to the human foetus, including birth defects and miscarriage. For participants on inavolisib: patients at risk for developing hyperglycemia may initiate oral type 2 diabetes medication where allowed by local regulations. In addition, any patient may be instructed to utilise a glucometer to monitor fasting glucose at home daily. It is unknown whether the IMPs might affect an unborn child therefore, WOCBP will be informed of potential risks associated with pregnancy and will be offered options to avoid pregnancy. Breach of confidentiality may be a concern therefore, a participant will only be identified by means of a participant identification number and their identity will never be disclosed. Risk of incurring additional costs will be addressed by assuring the participant that all extra costs will be covered by the sponsor.
Blood collection might cause pain, and there is a small risk of bleeding, bruising, or infection at the place where the needle is inserted. Rarely do some people experience dizziness, upset stomach, or fainting.
The radiation exposure from the CT scan is low and is not likely to adversely affect patients. However, the effects of radiation add up over a lifetime. The doctor may wish to use contrast agents, referred to as “dyes,” to increase visibility. The use of intravenous contrast during a CT scan can be associated with a warm, flushed sensation during the injection and a metallic taste in the mouth. It could also cause allergic reactions, decreased kidney function, and in very rare cases, anaphylactic shock (low blood pressure, loss of consciousness, and severe loss of body fluid that can lead to shock or death). CT scans are a necessary part of this study with the aim of assessing the course of the disease.
Alternatively, the doctor may evaluate the abdomen and pelvis by MRI. An MRI scanner uses electromagnetic radiation (radio waves) in a strong magnetic field. Some people may become anxious or experience discomfort in the confined space of an MRI scanner. If participants do experience discomfort at any time during the scan, they will be able to alert the staff by pressing on a call button provided. There are no proven long-term risks related to MRI scans as used in this research study. An MRI is considered safe when performed at a centre with appropriate procedures. However, the magnetic attraction for some metal objects can pose a safety risk, so metal objects mustn’t be taken into the scanner room.
Bone scans (or bone scintigraphy) use radionuclides containing radioactivity called gamma rays. A controlled amount of radiopharmaceutical will be used to minimise exposure. For the electrocardiogram participants will have adhesive patches placed on the chest, arms, and legs. In some areas, it may be necessary to shave a small spot. After an ECG, participants may have mild irritation, slight redness, and itching at the places on their skin where the recording patches are placed. Some risks are unknown or do not often happen when participants take the study drug. Participants will be informed in a timely manner of any new information, findings, or changes.

Health condition(s) or problem(s) studied | Early breast cancer |
Intervention | This trial is a multicentre, open-label, non-comparative, Phase II, biomarker-driven adjuvant treatment study involving the periodic collection and analysis of blood samples from patients with HR-positive/HER2-negative early-stage BC at higher risk of relapse, who have undergone surgery within the previous 5 years, with no evidence of locoregional, contralateral, or distant disease. The study design is composed of an initial pre-screening phase, a molecular follow-up phase (ctDNA surveillance phase), and an interventional therapeutic phase (treatment phase). After informed consent is obtained, an estimated total of 1,260 eligible patients will enter a ctDNA surveillance in which primary tumour tissue and matched normal blood will be collected from each patient to obtain a patient-specific somatic mutations panel (tumour signature). At the event of ctDNA positivity, patients will be screened to enter the treatment phase of the study. Upon confirmed eligibility, a total of 40 patients will be allocated in one of the following trial's arms adopting a sequential recruitment strategy: Arm A: Control Arm (n = 10) Patients must continue the same standard ET, prescribed as per standard practice, used in the surveillance phase. Changes in ET are not allowed. Arm B: Experimental Arm with giredestrant (n = 10) Giredestrant: 30 mg will be administered PO QD on Days 1 to 28 of each 28-day cycle up to 5 years or until disease recurrence, unacceptable toxicity, or treatment/study discontinuation (whichever occurs first). Arm C: Experimental Arm with giredestrant + abemaciclib (n = 10) Giredestrant: 30 mg will be administered PO QD on Days 1 to 28 of each 28-day cycle up to five years or until disease recurrence, unacceptable toxicity, or treatment/study discontinuation (whichever occurs first). Abemaciclib 150 mg will be taken PO BID (two intakes for a total daily dose of 300 mg) during each 28-day cycle up to 2 years or until disease recurrence, unacceptable toxicity, or treatment/study discontinuation (whichever occurs first). Arm D: Experimental Arm with giredestrant + inavolisib (n = 10) Giredestrant: 30 mg will be administered PO QD on Days 1 to 28 of each 28-day cycle up to 5 years or until disease recurrence, unacceptable toxicity, or treatment/study discontinuation (whichever occurs first). Inavolisib: 9 mg will be administered PO QD on Days 1 to 28 of each 28-day cycle up to 2 years or until disease recurrence, unacceptable toxicity, or treatment/study discontinuation (whichever occurs first). If the strategy of ctDNA monitoring enables physicians to identify patients at high risk of relapse and assess whether treatment at molecular relapse can improve outcome, new cohorts may be added to the study. Note I: In addition to the treatments described on each of the treatment arms, LHRH agonist will be administered to male participants and premenopausal/perimenopausal participants according to local prescribing information. The patient should be supplied with the previous LHRH they were taking. Note II: During the length of the study, additional treatment arms may open to stay up to date with the most recent advances in oncology, and to be able to provide the best treatment options to patients in this study. Because of that, the N of patients screened to enter the treatment phase may increase. In the meanwhile, serial assessment of ctDNA will be continuously performed every three months during the first year and every 6 months thereafter until EoS (End of Study) to correlate any ctDNA variations with response. Patients discontinuing the study treatment period will enter a post-treatment follow-up period during which survival and new anti-cancer therapy information will be collected every three months (±14 days) from the last dose of study treatment up to the EoS. Arm extensions: After initiation of study treatments, data obtained from the serial assessment of ctDNA will also be used to confirm the feasibility of eventual arms extensions, with a maximum of two arms that could be expanded (10 additional patients will be enrolled in each of the selected arms). The expansion will be approved when the arm complies with the following criteria: 1. If at 3 months, a 90% ctDNA decrease is observed in at least 30% patients and if after three additional months, a 90% ctDNA decrease is maintained in at least 20% patients In this case, 10 additional patients will be enrolled in the specific experimental arms that meet these requirements (n = 20). 2. If all three experimental arms fulfil the criteria, the two arms with the highest proportion of patients with the highest proportion of 90% decrease will be the ones expanded. 3. If cohorts remain too similar (no clear "winners"), the decision will be taken by the Steering Committee based on the duration of the response and the safety and toxicity of each specific treatment. 4. If none of the arms fulfil the specific expansion criteria, the Steering Committee will evaluate the data further and may nominate the two arms with the strongest signal of ctDNA decreases for further expansion. Sequential recruitment will be adopted, and the different treatment arms will be filled following order below: 1. Control arm A (for patients with PIK3CAwt tumours, or patients with PIK3CAmut tumours that do not fulfil the specific criteria to enter arm D) and arm D (for patients with PIK3CAmut tumours that fulfil the specific criteria to enter arm D). 2. Once arm A is closed, patients will be included in arm B (for patients with PIK3CAwt tumours, or patients with PIK3CAmut tumours that do not fulfil the specific criteria to enter arm D. Also for patients with PIK3CAmut tumours that fulfil the specific criteria to enter arm D once arm D is completed). 3. Once arms A and B are closed, patients will be included in arm C (for patients with PIK3CAwt tumours, or patients with PIK3CAmut tumours that do not fulfil the specific criteria to enter arm D. Also for patients with PIK3CAmut tumours that fulfil the specific criteria to enter arm D once arm D is completed). Depending on the number of patients with PIK3CAmut tumours included in arms B and C, up to five more patients with these mutations might be included in these arms depending on the Steering Committee decision. |
