ATYR Should I Buy

Leerink analyst Faisal Khurshid keeps an Outperform rating on aTyr Pharma after the company said the Phase 3 EFZO-FIT trial of efzofitimod in pulmonary sarcoidosis failed to meet its primary endpoint of steroid reduction. While aTyr plans to engage with the FDA on a potential path forward, Leerink's expectations are low given the primary endpoint miss and unclear relevance of KSQ-Lung score improvements alone, the analyst tells investors in a research note. Going into the readout, the firm expected a primary endpoint miss would see 80%-90% share downside. aTyr Pharma shares are down 82%, or $4.97, to $1.07 in early trading.
