Amarin’s icosapent ethyl shows survival benefit in cancer trial
Amarin Corporation (NASDAQ:AMRN) reported Phase 3 trial results for icosapent ethyl in colorectal cancer liver metastases. The primary endpoint of progression-free survival was not met, but the key secondary endpoint of overall survival showed a statistically significant benefit. The five-year overall survival estimate was 62.0% with icosapent ethyl versus 45.1% with placebo. The drug was found to be safe and well tolerated.
