Mobile Health for Adherence in Breast Cancer Patients
Recruiting
This clinical trial compares the use of the connected customized treatment platform (CONCURxP), consisting of using a medication monitoring device called WiseBag along with text message reminders for missed or extra medication events, to enhanced usual care (EUC), where patients only use the WiseBag, to monitor medication adherence in patients with metastatic breast cancer who are taking a CKD4/6 inhibitor. To ensure CDK4/6 inhibitors achieve their full clinical benefit, patients need to take th... Read More

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
Recruiting
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).
