Numerous clinical trials evaluate letrozole across Early Phase 1 through Phase 4 interventional settings, encompassing major indications such as hormone receptor-positive breast cancer, polycystic ovary syndrome, uterine fibroids, infertility, and low-grade serous ovarian carcinoma. Supported by academic medical centers, government institutes such as the NICHD, and pharmaceutical companies like Eli Lilly, these protocols demonstrate varying recruitment statuses ranging from completed and actively recruiting to terminated studies.
