Gold bars to be exempt from tariffs, White House clarifies
SAN DIEGO - A recent post hoc analysis of a Phase 1b/2a clinical trial has revealed that efzofitimod, a therapeutic candidate developed by aTyr Pharma Inc. (NASDAQ:ATYR), significantly reduced the relapse rate in patients with pulmonary sarcoidosis compared to lower doses and placebo. The study, published in the European Respiratory Journal, highlights the potential of efzofitimod to maintain disease control while reducing or eliminating the need for corticosteroids, which are commonly used but can have severe side effects.
In the 24-week clinical trial, 54.4% of patients in the subtherapeutic group (1.0 mg/kg efzofitimod and placebo) experienced a relapse after tapering off corticosteroids, in contrast to only 7.7% in the therapeutic group (3.0 and 5.0 mg/kg efzofitimod). The median time-to-first-relapse was also significantly shorter for the subtherapeutic group at 126 days, with only one of 17 patients in the therapeutic group relapsing by the study's end.
Dr. Ogugua Ndili Obi, the lead author of the paper, emphasized the clinical importance of these findings, noting the impressive low relapse rate and significant difference in time-to-first-relapse. Efzofitimod's ability to control the disease without the adverse effects of long-term steroid use could be highly beneficial for patients.
Efzofitimod functions by selectively modulating activated myeloid cells through neuropilin-2 to resolve inflammation without immune suppression, potentially preventing the progression of fibrosis. The drug is currently being investigated in a global pivotal Phase 3 study and has received orphan drug designation in the U.S., E.U., and Japan for sarcoidosis, as well as Fast Track designation in the U.S. for pulmonary sarcoidosis.
Pulmonary sarcoidosis affects nearly 200,000 Americans, with treatments limited to corticosteroids and other immunosuppressive therapies that can have limited efficacy and intolerable side effects. The promise of efzofitimod as a new treatment option is significant, with the potential to reduce or avoid steroid-related toxicity.
This article is based on a press release statement from aTyr Pharma, Inc. The company is at the forefront of developing tRNA synthetase biology-based therapies for fibrosis and inflammation, aiming to uncover new therapeutic intervention points and signaling pathways.
"In other recent news, Jefferies has given a 'Buy' rating to aTyr Pharma, highlighting the potential of efzofitimod, the company's lead candidate, in treating pulmonary sarcoidosis. Efzofitimod has demonstrated promising efficacy in Phase 1/2 studies, leading to a decrease in steroid use among pulmonary sarcoidosis patients. A more comprehensive Phase 3 randomized controlled trial is underway, with topline data anticipated for release in the third quarter of 2025.
Simultaneously, aTyr Pharma is conducting a Phase 2 trial in systemic sclerosis-associated interstitial lung disease, with interim results projected for the second quarter of 2025. Jefferies suggests that efzofitimod could become the first approved treatment for pulmonary sarcoidosis and may be applicable to a wider range of interstitial lung diseases.
In terms of financials, Jefferies has projected conservative peak sales estimates of approximately $400 million in the U.S. for pulmonary sarcoidosis and around $100 million for systemic sclerosis-associated interstitial lung disease. Given aTyr Pharma's current enterprise value of roughly $50 million, Jefferies has initiated coverage with a positive outlook and a price target that indicates substantial upside potential for the stock. These are some of the recent developments for aTyr Pharma."
