aTyr Pharma’s Phase 3 EFZO-FIT™ study of efzofitimod for pulmonary sarcoidosis received a positive safety review from an independent data and safety monitoring board (DSMB). The DSMB recommended the continuation of the study without modifications. This interim analysis marks the fourth such review for the ongoing trial.
This positive safety assessment is crucial for the development of efzofitimod as a potential chronic treatment for pulmonary sarcoidosis. A clean safety profile is paramount, particularly given the goal of positioning efzofitimod as a potential replacement or reduction for the long-term use of corticosteroids, which carry significant side effects. Confirming the safety of efzofitimod at this stage increases the likelihood of its adoption by physicians and patients if the trial ultimately demonstrates efficacy. This positive development also strengthens the potential for efzofitimod to address the unmet need for safer and more effective treatments for this debilitating lung disease.
The EFZO-FIT™ trial is a global, randomized, double-blind, placebo-controlled study involving 268 patients across the US, Europe, Japan, and Brazil. Patients receive either 3.0 mg/kg or 5.0 mg/kg of efzofitimod or a placebo intravenously once a month for a year. The study design includes a mandatory reduction in steroid use, with the primary endpoint being steroid reduction. Secondary endpoints assess lung function and sarcoidosis symptoms.
This positive DSMB recommendation significantly de-risks the efzofitimod program and bolsters confidence in its potential. The outcome sets the stage for the anticipated topline results expected in the third quarter of this year. Positive efficacy results, combined with the confirmed safety profile, could pave the way for regulatory submissions and potentially offer a much-needed new treatment option for patients with pulmonary sarcoidosis.
