PFS Extended by 4.9 Months but Failed to Reach Statistical Significance: Reflections on the Status Quo and Challenges of Oral SERDs in First-Line Endocrine Therapy from the persevERA BC Study
At a recent international breast cancer academic conference, Professor Nicholas C. Turner from The Royal Marsden Hospital and the Institute of Cancer Research (ICR) in the UK presented the highly anticipated primary analysis results of the Phase III persevERA BC study. This study aimed to evaluate the efficacy and safety of a novel oral selective estrogen receptor degrader (SERD), Giredestrant (GIRE), in combination with the CDK4/6 inhibitor Palbociclib (PALBO), compared to the standard aromatase inhibitor (AI) Letrozole (LET) plus Palbociclib, in the first-line treatment of estrogen receptor-positive, HER2-negative (ER+/HER2-) locally advanced or metastatic breast cancer (LA/mBC).
