The company says that elacestrant is the first oral selective estrogen receptor degrader (SERD) demonstrating a significant improvement in Progression-free survival (PFS) vs. standard of care (SOC) with manageable safety.
Elacestrant significantly reduced the risk of disease progression or death by 30% in all patients and 45% in patients with an ESR1 mutation.
PFS was prolonged in all patients.
PFS rate at 12 months with elacestrant was 22.3% vs. 9.4% with SOC in the overall population and 26.8% vs. 8.2% in the ESR1 mutation population
The most common treatment-emergent adverse events (AEs) in patients receiving elacestrant were mild or moderate gastrointestinal events.
