New treatment option for Breast Cancer
Official title Evaluating the Addition of Adjuvant Chemotherapy to Ovarian Function Suppression Plus Endocrine Therapy in Premenopausal Patients With pN0-1, ER-Positive/HER2-Negative Breast Cancer and an Oncotype Recurrence Score Less Than or Equal to 25
ClinicalTrials.gov ID: NCT05879926
What this study is testing
What is Ovarian Function Suppression + Aromatase Inhibitor?
Ovarian Function Suppression + Aromatase Inhibitor is an investigational medicine, given as a monthly, being studied as a potential treatment for breast cancer.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This Phase III Trial will determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).
- Phase 3: a large, late-stage study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.

Who can join
- A patient cannot be considered eligible for this study unless ALL of the following conditions are met.
- The patient or a legally authorized representative must provide study-specific informed consent prior to pre-entry and, for patients treated in the U.S., authorization permitting release of personal health information.
- Female patients must be greater than or equal to 18 years of age.
- Patients must be premenopausal (evidence of functioning ovaries) at the time of pre-entry. For study purposes, premenopausal is defined as:
- Age 50 years or under with spontaneous menses within 12 months; or
- Age greater than 50-60 years with spontaneous menses within 12 months plus follicle-stimulating hormone (FSH) and estradiol levels in the premenopausal range; or
- Patients with amenorrhea due to IUD or prior uterine ablation must have FSH and estradiol levels in the premenopausal range; or
- Patients with prior hysterectomy must have FSH and estradiol levels in the premenopausal range.
- The patient must have an ECOG performance status of less than or equal to 2 (or Karnofsky greater than or equal to 60%).
- Patients may have ipsilateral or contralateral synchronous breast cancer if the highest stage tumor meets entry criteria, and the other sites of disease would not require chemotherapy or HER2-directed therapy.
- Patients may have multicentric or multifocal breast cancer if the highest stage tumor meets entry criteria, and the other sites of disease would not require chemotherapy or HER2-directed therapy.
- Patient may have undergone a total mastectomy, skin-sparing mastectomy, nipple-sparing mastectomy, or a lumpectomy.
- For patients who undergo a lumpectomy, the margins of the resected specimen or re-excision must be histologically free of invasive tumor and DCIS (ductal carcinoma in situ) with no ink on tumor as determined by the...
- For patients who undergo mastectomy, the margins must be free of residual gross tumor. (Patients with microscopic positive margins are eligible if post-mastectomy RT (radiation therapy) of the chest wall will be...
- Patient must have undergone axillary staging with sentinel node biopsy (SNB), targeted axillary dissection (TAD), or axillary lymph node dissection (ALND).
- The following staging criteria must be met postoperatively according to AJCC 8th edition criteria:
- By pathologic evaluation, primary tumor must be pT1-3. (If N0, must be T1c or higher.)
- By pathologic evaluation, ipsilateral nodes must be pN0 or pN1 (pN1mi, pN1a, pN1b, pN1c).
- Patients with positive isolated tumor cells (ITCs) in axillary nodes will be considered N0 for eligibility purposes.
- Patients with micrometastatic nodal involvement (0.2-2 mm) will be considered N1.
- Oncotype DX RS (recurrence score) requirements\ :
- If node-negative:
- Oncotype DX RS must be RS 21-25, or

- The tumor must be HER2-negative by current ASCO/CAP (American Society of Clinical Oncology/College of American Pathologists) guidelines based on local testing results.
- The interval between the last surgery for breast cancer (including re-excision of margins) and pre-entry must be no more than 16 weeks.
- Short course of endocrine therapy of less than 6 weeks duration before pre-entry is acceptable either as neoadjuvant or adjuvant therapy. An Oncotype DX RS must be performed on core biopsy specimen obtained prior to...
