Optimising Adjuvant Chemotherapy Prescription in Young Patients With Hormone-dependent Breast Cancer Using Genomic Tests

Rationale: Around 70 to 80% of breast cancers are so-called "hormone-dependent" (HR+)/HER2-. For more than 50 years, studies have shown that chemotherapy and optimised hormonal treatments (hormone therapy), including a drug associated with ovarian suppression (OFS), improve survival in patients with these cancers, which are characterised by a high risk of relapse. However, younger patients suffer more side effects than older women, particularly from chemotherapy. This can affect their quality of life and reduce their ability to work. For post-menopausal women, genetic tests exist to assess whether chemotherapy is really necessary in addition to hormonal treatment. However, for high-risk premenopausal patients, chemotherapy is still systematically recommended, as no study has proved that it can be safely avoided. Clinical trials based on risk stratification using genetic tests have not been conclusive, but the majority of premenopausal women included had not received optimal hormone treatment. It is possible that the beneficial effect of chemotherapy is partly due to the artificial menopause it induces. Some experts believe that, for patients with a high clinical risk but a low genetic risk, an optimised hormonal treatment (drug + OFS) could suffice, without the need for chemotherapy. Objectives: Main objective: The aim of the study is to determine whether the use of a genetic test (Prosigna®) to decide whether or not to administer chemotherapy produces results as good as standard treatment (systematic chemotherapy) in premenopausal women with hormone-dependent (HR+) breast cancer/HER2-, by assessing their risk of cancer recurrence. The secondary objectives include verifying whether, in patients with a low Prosigna® score (around 70% of cases), optimised hormonal treatment (including suppression of ovarian function) is as effective as chemotherapy combined with hormonal in treatment preventing cancer recurrence. The study also seeks to compare the efficacy of treatment Prosigna®-guided versus systematic chemotherapy in terms of recurrence and quality of life, as well as economic aspects. Finally, the aim is to understand patients' concerns about the concept of reducing treatment (therapeutic de-escalation) and the way in which this information is communicated to them. The primary endpoint of the study is to measure the time elapsed between the start of participation in the study and the appearance of an event indicating a return of the cancer. This includes the return of cancer in the same breast or neighbouring areas, the spread of cancer to other parts of the body, the appearance of new cancer in the other breast or death from any cause. Trial Population: The study includes women major premenopausal diagnosed with invasive, hormone receptor-positive (ER+) and HER2-negative breast cancer. Patients must have undergone breast and axillary surgery recent and have a tumour sample suitable for analysis by the testProsigna® . They must be able to receive the study treatments Postmenopausal women, women with stage IV breast cancer, women who have already received adjuvant systemic treatment (except short neoadjuvant hormone therapy), women with a recent history of invasive cancer, pregnant women or women who are breast-feeding will not be able to take part in the study. Interventions: After agreeing to take part, patients will enter the pre-inclusion period (up to 28 days before randomisation), during which the investigator will carry out all the necessary tests to assess their eligibility. The investigator will then randomise the patients to find out which treatment they have been assigned, no more than 2 weeks later: the experimental group will receive a treatment decided on the basis of the results of a genomic test: either chemotherapy and hormone therapy, or hormone therapy alone. The control group will receive the standard treatment. The treatment and follow-up phases are the same as for standard care. Information on the quality of life patient's will and other information (associated costs, perception of their participation in the study, etc.) also be collected by means of questionnaires completed by the patients during the 5 years following randomisation.

Combined Chemo-immunotherapy Plus SBRT in Neoadjuvant Treatment for Luminal Subtype Breast Cancer

This study is a prospective, randomized controlled clinical trial designed to evaluate the efficacy and safety of combining radiotherapy, chemotherapy, and immunotherapy in the neoadjuvant treatment of high-risk HR+/HER2- breast cancer patients. The study plans to enroll treatment-naïve HR+/HER2- breast cancer patients aged 18-75 with high-risk features (e.g., tumor size ≥3 cm or lymph node positivity, Ki-67 ≥20%). Eligible subjects will be randomized in a 1:1 ratio into two groups: the control group will receive neoadjuvant chemotherapy (nab-paclitaxel followed by epirubicin + cyclophosphamide) in combination with sintilimab immunotherapy; the experimental group will receive the same chemotherapy and immunotherapy regimen with the addition of stereotactic body radiotherapy (SBRT) administered early during treatment, at a prescribed dose of 8 Gy per fraction for 3 fractions, with one fraction per day. The study has dual primary endpoints: pathological complete response (pCR,) and objective response rate (ORR ). Secondary endpoints include 3-year event-free survival (EFS), incidence of adverse events (CTCAE v5.0), and postoperative cosmetic outcomes of the breast. The study design incorporates hierarchical testing to control for multiplicity, and long-term follow-up is planned to evaluate survival benefits. The study has been approved by the ethics committee, and all participants are required to provide written informed consent. The results are expected to offer a novel neoadjuvant treatment strategy for high-risk HR+/HER2- breast cancer patients and improve their therapeutic outcomes.

Marker - Adjusted Therapy Comparing Adjuvant Elacestrant With Standard Endocrine Treatment in Genomically and/or Clinically High-risk ER+/HER2- eBC

In this clinical trial, the Sponsor plans to investigate whether patients with HR+/HER2- eBC identified during routine clinical assessments and treatments as having intermediate to high-risk (based on Oncotype DX® or similar tests and on response assessment to 2-6 weeks of preoperative ET) achieve a survival benefit from an initial 5-years use of elacestrant (with or without a CDK 4/6 inhibitor) followed by SoC ET for further 0-2.5 years in comparison to at least 5 up to 7.5 years SoC ET therapy (+/- CDK4/6 inhibitor). Based on several studies in the metastatic setting, it is reasonable to assume that the adjuvant use of elacestrant with or without CDK 4/6 inhibitors will prevent or delay the activation of mechanisms conferring resistance to ET (e.g., ESR1 mutations).
