A Phase IIIb, Single-Arm, Open-Label Study Evaluating Adherence, Tolerability, and Patient Reported Outcomes (PRO) of Giredestrant in Patients With ER+/HER2- Early Breast Cancer Who Are Intolerant to Adjuvant Aromatase Inhibitor Therapy

Summary

The purpose of this study is to understand treatment adherence and patient-reported outcomes of switching to giredestrant due to prior aromatase inhibitor (AI) intolerance. Giredestrant will be administered as adjuvant endocrine therapy for participants with low-, medium-, and high-risk, Stage I-III, histologically confirmed, estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (HER2-), early breast cancer (eBC), as defined by the investigator. Participants will enroll if considered to be intolerant to a prior adjuvant AI therapy.
