Brief Summary:

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate, goserelin acetate, leuprolide acetate, anastrozole, letrozole, or exemestane, may fight breast cancer by lowering the amount of estrogen the body makes. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet know whether hormone therapy is more effective when given with or without everolimus in treating breast cancer.

PURPOSE: This randomized phase III trial studies how well giving hormone therapy together with or without everolimus work in treating patients with breast cancer.


Condition or disease Intervention/treatment Phase
Breast Cancer Drug: anastrozole Drug: everolimus Drug: exemestane Drug: goserelin acetate Drug: letrozole Drug: leuprolide acetate Drug: tamoxifen citrate Other: placebo Phase 3

Detailed Description:

OBJECTIVES:

Primary

  • To compare whether the addition of one year of everolimus (10 mg daily) to standard adjuvant endocrine therapy improves invasive disease-free survival (IDFS) in patients with high-risk, hormone-receptor (HR)-positive, and human epidermal growth factor receptor (HER)2-negative breast cancer.

Secondary

  • To compare whether the addition of one year of everolimus to standard adjuvant endocrine therapy improves overall survival (OS) and distant recurrence-free survival (DRFS) in this patient population.
  • To evaluate the safety, toxicities, and tolerability of one year of everolimus in combination with standard adjuvant endocrine therapy and to compare it with standard adjuvant endocrine therapy plus placebo in this patient population.
  • To determine whether the benefit of one year of everolimus use in addition to standard adjuvant endocrine therapy varies by recurrence score (RS), nodal status, or other commonly used prognostic factors.
  • To evaluate adherence to 1-year treatment of everolimus in comparison to placebo in addition to standard adjuvant endocrine therapy in this patient population.
  • To collect specimens in order to evaluate biomarkers of therapeutic efficacy. (exploratory)

OUTLINE: This is a multicenter study. Patients are stratified according to risk level (node-negative and recurrence score [RS] > 25 in the primary tumor, and a tumor measuring ≥ 2 cm in greatest diameter treated with adjuvant therapy vs 1-3 positive lymph nodes and RS > 25 treated with adjuvant therapy vs ≥ 4 positive lymph nodes [any RS value] treated with adjuvant therapy vs ≥ 4 positive lymph nodes [any RS value] prior to or after neoadjuvant chemotherapy). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive an approved endocrine therapy comprising tamoxifen citrate*, goserelin acetate** or leuprolide acetate**, or aromatase inhibitor (anastrozole, letrozole, or exemestane) for 2-5 years. Patients also receive a placebo orally (PO) daily for 1 year in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients receive an approved endocrine therapy regimen as in arm I. Patients also receive everolimus PO daily for 1 year in the absence of disease progression or unacceptable toxicity.

NOTE: *Men receive tamoxifen citrate PO for 5 years.

NOTE: **Goserelin acetate or leuprolide acetate is given if patient is or becomes postmenopausal.

Blood and tissue samples are collected for biomarker studies.

After completion of study treatment, patients are followed up every 6 months for 2 years and then yearly thereafter for 10 years.

Criteria

DISEASE CHARACTERISTICS:

  • Patients must have a histologically confirmed diagnosis of invasive breast carcinoma with positive estrogen (ER)- and/or progesterone-receptor (PR) status, and negative human epidermal growth factor receptor (HER)2, for whom standard adjuvant endocrine therapy is planned

    • ER and PR positivity must be assessed according to American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines as either ER or PR ≥ 1% positive nuclear staining
    • HER2 test result negativity must be assessed as per ASCO/CAP 2013 guidelines using IHC, ISH or both.

HER2 is negative if a single test (or all tests) performed in a tumor specimen show:

  1. IHC negative (0 or 1+)
  2. ISH negative using single probe or dual probe. If IHC is 2+, evaluation for gene amplification (ISH) must be performed and the ISH must be negative; ISH is not required if IHC is 0 or 1+.

HER2 equivocal is not eligible.

  • Patients must not have metastatic breast cancer (stage IV disease); patients with multifocal, multicentric, and synchronous bilateral, and primary inflammatory breast cancers are allowed

    • Multifocal disease is defined as more than one invasive cancer < 2 cm from the largest lesion within the same breast quadrant
    • Multicentric disease is defined as more than one invasive cancer ≥ 2 cm from the largest lesion within the same breast quadrant or more than one lesion in different quadrants
    • Synchronous bilateral disease is defined as invasive breast cancer with positive lymph nodes (axillary or intramammary) in at least one breast, diagnosed within 30 days of each other

  • Patients must be high risk by belonging to one of the following risk groups:

    • Completion of adjuvant chemotherapy and pathologically negative axillary nodes, and a tumor measuring ≥ 2 cm in greatest diameter, and an Oncotype DX® recurrence score (RS) > 25 (completed as standard of care). Patients with micrometastases as the only nodal involvement (pN1mi) are eligible, and will be categorized as node-negative.
    • Completion of adjuvant chemotherapy, and pathologically 1-3 positive lymph nodes, and either an Oncotype DX® RS > 25 (screened via S1007 or otherwise) or tumor tissue with pathological Grade III following local practice. If Oncotype DX is done, then RS must be > 25. If the test is not done, but the patient has Grade III disease then the patient is eligible and Oncotype DX does not need to be performed.
    • Completion of adjuvant chemotherapy and pathologically 4 or more positive lymph nodes.
    • Completion of neoadjuvant chemotherapy and 1 or more positive nodes pathologically determined prior to or after chemotherapy

  • Patients must have completed either breast-conserving surgery or total mastectomy, with negative margins and appropriate axillary staging; a negative margin is defined as no evidence of tumor or ductal carcinoma in situ (DCIS) at the line of resection; additional operative procedures may be performed to obtain clear margins

    • Patients who had breast-conserving surgery must have completed whole-breast radiation; use of regional nodal-basin radiation will be at the discretion of the investigator according to institutional guidelines
    • Patients with ≥ 4 positive lymph nodes must have completed breast/chest wall and nodal-basin radiation therapy according to standard-of-care guidelines before randomization; omission of radiation therapy is not allowed in this high-risk population of patients
    • Patients must be registered no sooner than 21 days after completion of radiation therapy and must have recovered (≤ grade 1) from any of the effects of radiation

  • Patients must have undergone axillary staging by sentinel-node biopsy or axillary lymph node dissection (ALND)

    • For patients with 1-3 positive lymph nodes, sentinel-node biopsy alone is allowed provided that the patient completed either whole-breast or chest-wall radiation and the primary tumor is < 5 cm
    • All patients with ≥ 4 positive lymph nodes must have completed ALND (with or without prior sentinel-node biopsy)

PATIENT CHARACTERISTICS:

  • Absolute Neutrophil Count ≥ 1,500/mL

  • Alkaline phosphatase ≤ 1.5 times IULN
  • Serum creatinine level ≤ IULN
  • Fasting cholesterol ≤ 300 mg/dL and triglycerides ≤ 2.5 times IULN; patients may be on lipid-lowering agents to reach these values

  • Patients with known hepatitis are not eligible
  • Patients must not have any known uncontrolled, underlying pulmonary disease
  • Patients must be able to take oral medications
  • Patients may not have any impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of blinded drug (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
  • Patients must not be pregnant or nursing

  • Women/men of reproductive potential must have agreed to use an effective non-hormonal contraceptive method during and for 8 weeks after completion of study therapy

    • In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy, or bilateral tubal ligation; corresponding procedures for men include castration, vasectomy, and barrier-contractive devices
    • If at any point a previously celibate patient chooses to become heterosexually active during the protocol therapy, he/she is responsible for beginning contraceptive measures
