What is the story about?
What's Happening?
The FDA has approved Eli Lilly's Inluriyo (imlunestrant) as a second-line treatment for ER-positive, HER2-negative advanced or metastatic breast cancer with ESR1 mutations. Inluriyo, an oral selective estrogen receptor degrader (SERD), demonstrated a 38% improvement in progression-free survival in the Phase III EMBER-3 study. The drug offers a new oral treatment option, potentially improving patient compliance and quality of life.
Why It's Important?
Inluriyo's approval represents a significant advancement in breast cancer treatment, particularly for patients with ESR1 mutations, which often lead to treatment resistance. By providing an oral treatment option, Inluriyo may improve patient compliance and quality of life, as it eliminates the need for injections. This development is crucial for the approximately 310,000 new cases of breast cancer expected in the U.S. in 2024, offering hope for better management of the disease.
What's Next?
Inluriyo is expected to be available in the U.S. in the coming weeks. Eli Lilly is also conducting ongoing studies to further explore the drug's efficacy in different settings, including the adjuvant setting for early breast cancer. The company is committed to advancing innovative, all-oral treatment approaches for breast cancer, potentially expanding the use of Inluriyo in other patient populations.
