aTyr Pharma, Inc. (Nasdaq: ATYR) (“aTyr” or “the Company”), a clinical stage biotechnology company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase platform, today announced the appointment of Jayant Aphale, Ph.D., as Vice President, Technical Operations. Dr. Aphale will serve as a member of the Company’s executive leadership team, overseeing manufacturing activities at contract development and manufacturing organizations and implementing strategies related to the continuous improvement of commercial manufacturing, supply chain management, process development of new products and product life cycle management.

“We are pleased to welcome Dr. Aphale, whose extensive experience in successfully implementing technical strategies for innovative therapeutic products at both biotechnology and pharmaceutical companies will be a valuable addition to aTyr,” said Sanjay S. Shukla, M.D., M.S., President and Chief Executive Officer of aTyr. “As we look towards releasing pivotal Phase 3 data for our lead therapeutic candidate, efzofitimod, in pulmonary sarcoidosis in the third quarter of 2025, we are focused on our ongoing preparation for the potential submission of a Biologics License Application (BLA) and subsequent commercialization, including manufacturing efzofitimod at commercial scale. Commercial manufacturing process validation, a critical component of a BLA submission, is on track to begin later this year, and we expect Dr. Aphale to play an instrumental role in helping to ensure the successful delivery of a potential new treatment option to patients in need.”

“I am excited to join aTyr at such an important time for the company as it heads towards the potential commercialization of efzofitimod,” said Dr. Aphale. “I look forward to supporting the company through this next inflection point and playing an integral role in helping to advance the first tRNA synthetase-derived product to market.”

Prior to joining aTyr, Dr. Aphale was Vice President, RNA Manufacturing & Process Development for Sarepta Therapeutics, Inc., where he designed the manufacturing processes and supply chains used to launch and commercialize three rare disease related novel therapies, including EXONDYS™, AMONDYS™ and VYONDYS™, and also focused on clinical and commercial manufacturing. Dr. Aphale has also previously worked at GSK Vaccines, Enobia Pharma, Acambis, Wyeth Vaccines, Diosynth RTP and Roche Diagnostics, among other companies.
