Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A significant number of patients relapse and eventually die, particularly if they were initially diagnosed with large nodes involvement and/or T3/4 diseases. When analyses focus on patients with ER+/Her2-negative breast cancer, with ≥4N+, 30% had relapsed at 5 years, emphasizing the need for new drugs in this setting (PACS01 data, UNICANCER internal data).

Strong evidence suggests that cross-talk between the phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway and ER signaling is linked to hormone resistance in breast cancer patients.

In the present study, we plan to evaluate the benefit from adding everolimus to standard endocrine treatments after three years of treatment for patient ER+/HER2- at high risk of relapse due to high nodes involvement (≥4) and/or persistent node involvement after neo-adjuvant chemotherapy.

Genomic signatures have emerged during the last 10 years as a new and additive means to evaluate more precisely long term prognosis, and in some instances the amount of benefit from chemotherapy or endocrine therapy in the adjuvant setting. Therefore, the UNIRAD study can be proposed to patients with 1-3 positive lymph nodes at primary surgery and a high risk of relapse with the EndoPredict test.

This study is a unique opportunity to prove the efficacy of everolimus in adjuvant setting. The study could be practice changing in case of positive results and could allow improving outcome of breast cancer patients presenting high risk of metastatic relapse.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

2. Histologically proven invasive unilateral or bilateral breast cancer (regardless of the morphological subtype),
3. Any T, M0
4. Patient with high risk of relapse according to one of the conditions below:

* at least 4 positive lymph nodes if the patient had primary surgery
* or at least 1 positive lymph node if surgery was conducted after neo adjuvant chemotherapy or hormone therapy of at least 3 months duration
* or 1-3 positive lymph nodes (pN1a, b, c) at primary surgery AND EPClin score ≥3.32867 Note: Access to primary tumor for patients with 1-3 node positive is mandatory. Patient with EPClin score \<3.32867 will not be randomized, but will be followed yearly during 10 years
5. ER+ and HER2 negative : Hormone receptor positive is defined as any staining on the primary tumor, HER2 negativity is defined as IHC 0-1+, or \[IHC 2+ and FISH or CISH non-amplified\]
6. Primary tumor completely resected (deep margins and overlying skin involvement allowed if fully resected)
7. Patients who will begin an adjuvant hormone therapy or have received a maximum of 4 years of adjuvant hormone therapy. Hormone therapy could be either +/- LH-RH agonists, letrozole, anastrozole or exemestane.
8. No clinically or radiologically detectable metastases at time of inclusion.
9. WHO Performance status (ECOG) of 0 or 1.
10. Adequate hematological function (neutrophil count ≥2x10⁹/L; platelet count ≥ 100x10⁹/L)
11. Adequate hepatic function: AST and ALT ≤2.5 ULN, alkaline phosphatases ≤2.5 ULN, total bilirubin ≤2 ULN
