Read MoreHide Full Article

aTyr Pharma, Inc. (LIFE - Free Report) announced that the FDA has granted Orphan Drug designation to its lead therapeutic candidate, efzofitimod (ATYR1923), for the treatment of systemic sclerosis (SSc, also called scleroderma).

The Orphan Drug designation is granted by the FDA to a drug or biologic intended to treat a rare disease or condition, which generally includes one that affects fewer than 200,000 individuals in the United States. The designation also includes incentives, including financial aid for clinical testing and seven-year marketing exclusivity in the event of regulatory approval.

The Orphan Drug designation for efzofitimod in SSc is the second such designation for the candidate.

Shares of aTyr Pharma were up 7.4% following the announcement of the news on Wednesday. However, the stock has declined 31.8% so far this year compared with the industry’s decrease of 13.9%.

The FDA has already granted an Orphan Drug designation to efzofitimod for the treatment of sarcoidosis.

Per the company, the lead indication for efzofitimod is pulmonary sarcoidosis, a form of interstitial lung disease ("ILD"). A placebo-controlled, multiple-ascending dose phase Ib/IIa study is evaluating efzofitimod for treating pulmonary sarcoidosis. Clinical proof of concept for efzofitimod has recently been established in the given study.

Data from the study demonstrated safety and consistent dose response and trends of benefit of efzofitimod versus placebo on key efficacy endpoints.

aTyr Pharma plans to initiate a registrational study of efzofitimod in pulmonary sarcoidosis in the third quarter of 2022.

Per the press release, SSc that occurs in the lungs is called SSc-ILD. Currently limited treatment options are available for SSc-ILD. Hence if successfully developed and upon potential approval, efzofitimod can serve an area of high unmet medical need.

aTyr Pharma currently has no approved product in its portfolio. Therefore, the successful development of efzofitimod and other pipeline candidates remains in key focus for the company.
