A Phase III Adjuvant Trial 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 (OFSET)
NRG Oncology
Summary
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).
Description
Younger age at diagnosis is an adverse prognostic factor in early breast cancer: women who are less than 35 years of age at diagnosis are more likely to die from their disease than their older counterparts following standard treatments. There remains a pressing need for advancements in therapeutic options for this patient population. One increasingly utilized option is ovarian suppression, which was first reported as treatment for advanced breast cancer in 1896 and has been examined in a multitude of clinical trials over the past century. As chemotherapeutic options became more commonplace for…

Interventions
- DrugOvarian Function Suppression + Aromatase Inhibitor
Aromatase inhibitor co-administered with a GnRH agonist for 5 years. The choice of AI is per investigator discretion. The choice of GnRH agonist and dosing schedule is per investigator's discretion. Options commonly include goserelin, leuprolide, or triptorelin given monthly or every-three-months. The dose and schedule of AI should be consistent with the drug package insert. Endocrine treatment beyond 5 years is at the investigator's discretion. Bilateral oophorectomy may substitute for ovarian suppression if desired.
- DrugAdjuvant Chemotherapy + Ovarian Function Suppression
Adjuvant chemotherapy of investigator's choice followed by an aromatase inhibitor (AI) co-administered with an GnRH agonist for 5 years. The choice of AI is per investigator discretion. The choice of GnRH agonist and dosing schedule is per investigator's discretion. Options commonly include goserelin, leuprolide, or triptorelin given monthly or every-three-months. The dose and schedule of AI should be consistent with the drug package insert. Endocrine treatment beyond 5 years is at the investigator's discretion.
