BCRX Stock Posts Worst Day In Over 6 Months After PHVS Trial Win In Rare Swelling Disease
BioCryst Pharmaceuticals (BCRX) shares fell 9% on Tuesday, their worst day in over 6 months, after competitor Pharvaris (PHVS) reported positive late-stage trial results for a rare swelling disorder treatment. PHVS shares rose 7% during trading and 3% after-hours. Orladeyo, BioCryst's approved treatment, generated over $2B in revenue since 2020 and is expected to bring in $625M-$645M this year. BioCryst is also developing a second treatment, navenibart, with late-stage data expected in 2027.
