Eli Lilly Inluriyo gets USFDA nod for adults with advanced breast cancer

Indianapolis:
In the Phase 3 EMBER-3 trial, Inluriyo reduced the risk of progression or death by 38% versus ET. Among patients with ESR1-mutated MBC, Inluriyo significantly improved progression-free survival (PFS) versus fulvestrant or exemestane, with a median PFS of 5.5 months vs 3.8 months (HR=0.62 [95% CI: 0.46-0.82]); p-value=0.0008.
Inluriyo is a treatment for ER+, HER2–, ESR1-mutated MBC. Some breast cancers develop ESR1 mutations that can cause estrogen receptors to become overactive and drive cancer growth. Inluriyo binds, blocks, and facilitates the degradation of these receptors, helping to slow disease progression. Its once-daily dosing provides patients with an oral treatment option.
“This therapy reflects our commitment to developing treatments that improve outcomes for people with breast cancer and represents an important step toward advancing innovative, all-oral treatment approaches,” said
The Inluriyo label contains a warning and precaution for embryo-fetal toxicity.
The FDA approval is based on the results of the EMBER-3 trial in the patient population harboring ESR1-mutated MBC (n=256). Patients received Inluriyo or ET as first-line treatment for MBC following recurrence on adjuvant aromatase inhibitor (AI), +/- prior CDK4/6 inhibitor (21%), or as second-line treatment for MBC following progression on AI, +/- prior CDK4/6 inhibitor (79%).
“This represents an important advancement for patients with ESR1-mutated MBC, a mutation found in nearly half of patients who have taken hormone therapies, often contributing to treatment resistance,” said
“The approval of Inluriyo expands the metastatic breast cancer treatment landscape for patients who test positive for the ESR1 mutation,” said
Inluriyo is also being studied in the ongoing Phase 3 EMBER-4 trial in the adjuvant setting for people with ER+, HER2– early breast cancer (EBC) at increased risk of recurrence, which is enrolling approximately 8,000 patients worldwide.
Inluriyo is expected to be available in
