A New Breakthrough in Adjuvant Endocrine Therapy: lidERA Study Confirms Giredestrant Significantly Improves iDFS in Pre/Postmenopausal HR+ Early Breast Cancer
At the recent 2026 ASCO Annual Meeting, Professor Peter Schmid, representing the lidERA study group from the Barts Cancer Institute, Queen Mary University of London, detailed the efficacy and safety analysis results based on menopausal status (pre/perimenopausal vs. postmenopausal) from the Phase III lidERA BC clinical trial. The study aims to evaluate the clinical value of Giredestrant (GIRE), a next-generation oral selective estrogen receptor degrader (SERD), in the adjuvant treatment of patients with estrogen receptor-positive (ER+), HER2-negative (HER2-) early breast cancer (eBC).
