aTyr Pharma Announces Positive End-of-Phase 2 Meeting with FDA on Efzofitimod for the Treatment of Pulmonary Sarcoidosis
“We are pleased with the very productive feedback we received from the FDA, in particular, the emphasis around the steroid-sparing effects of efzofitimod. As the most advanced clinical development program for pulmonary sarcoidosis, we have an opportunity to establish efficacy endpoints that, if successful in demonstrating clinically meaningful treatment effects, will serve as a basis for future FDA review,” said
Following the FDA’s review of the data package, including data from the nonclinical program, early clinical trials and the recently completed Phase 1b/2a study, the Company will proceed with the advancement of efzofitimod. The FDA discussed endpoints detailed by the Company in its proposed registrational study and prioritization of outcome measurements that would best support the evaluation of efzofitimod’s efficacy. The FDA advised the continued evaluation of multiple doses of efzofitimod in a longer duration study to establish a controlled safety database that supports the determination of the optimal dose for chronic use.
“As an attendee of the meeting, I came away impressed that the FDA appreciated the need for a therapeutic that demonstrates a steroid-sparing effect. This is an important step forward, as the well-recognized complications of steroid use in sarcoidosis present a compelling rationale for the potential use of efzofitimod in sarcoidosis patients,” said
“On behalf of the sarcoidosis community, we are grateful to aTyr for including us in this meeting and the FDA for their commitment to improving the lives of those with sarcoidosis and for the continued development of efzofitimod as a potential new therapy,” said
About Efzofitimod
aTyr is developing efzofitimod as a potential therapeutic for patients with severe inflammatory lung diseases. Efzofitimod, a fusion protein comprised of the immuno-modulatory domain of histidyl-tRNA synthetase fused to the FC region of a human antibody, is a selective modulator of neuropilin-2 that downregulates innate and adaptive immune response in inflammatory disease states. aTyr’s lead indication for efzofitimod is pulmonary sarcoidosis, a major form of interstitial lung disease. Clinical proof-of-concept for efzofitimod was recently established in a Phase 1b/2a multiple-ascending dose, placebo-controlled study of efzofitimod in patients with pulmonary sarcoidosis, which demonstrated safety and a consistent dose response and trends of benefit of efzofitimod compared to placebo on key efficacy endpoints, including steroid reduction, lung function, clinical symptoms and inflammatory biomarkers.
