aTyr Plans to Submit New Drug Application for efzofitimod Next Month
"2026 is off to a productive start, as we now have a clear path forward for efzofitimod in pulmonary sarcoidosis, a major form of interstitial lung disease, following our recent Type C meeting with the U.S. Food and Drug Administration," said Sanjay S. Shukla, president and CEO of aTyr. "Based on feedback from the FDA, we plan to file an investigational new drug application next month for a new Phase 3 study in patients with chronic, symptomatic pulmonary sarcoidosis with restrictive lung disease utilizing forced vital capacity as the primary endpoint of the study and the King's Sarcoidosis Questionnaire-Lung score as a key secondary endpoint. We look forward to the continued advancement of efzofitimod in this form of ILD where there remains a high unmet medical need."
