FDA approves nerandomilast for treatment of idiopathic pulmonary fibrosis in adults

​Idiopathic pulmonary fibrosis (IPF) has few treatment options and currently relies on antifibrotic agents (nintedanib and pirfenidone) and supportive therapy. Nerandomilast, an oral phosphodiesterase-4 (PDE-4) inhibitor, is the first new treatment for IPF approved by the Food and Drug Administration (FDA) in more than 10 years.

One randomized, double-blind, placebo-controlled phase 3 trial demonstrated that people with IPF taking nerandomilast had a significantly smaller decline in forced vital capacity (FVC) compared with placebo-treated groups over a period of 1 year.[84]

Nerandomilast can be used alone or in combination with antifibrotic therapy.

This treatment has the potential to impact the care of many patients, including those with:

  • Intolerance to an antifibrotic agent.

  • Continued worsening in lung function despite use of an antifibrotic agent.
