AstraZeneca at ASBMR 2026: rare disease push hinges on new bone drug
AstraZeneca (AZN) presented data on efzimfotase alfa, a potential treatment for hypophosphatasia, at ASBMR 2026. The drug missed the primary endpoint in the HICKORY study but showed improvements in secondary measures. Management maintained peak sales guidance of $3B-$5B and highlighted its potential over the current standard, Strensiq. AZN trades at a P/E of 23.7 with a $246B market cap, and analysts suggest it may be undervalued.
