About Autoimmune PAP

Autoimmune PAP is a rare lung disease characterized by the abnormal build-up of surfactant, consisting of proteins and lipids, in the lung’s alveoli. While in a healthy lung surfactant is cleared, in autoimmune PAP it is left to accumulate causing impaired gas transfer, resulting in clinical symptoms of shortness of breath, often with cough and frequent fatigue.

The company now plans to submit applications to the European Medicines Agency (EMA) and the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) seeking approval for Molbreevi by the end of the first quarter of 2026.

“We believe the considerable body of data in the application demonstrates MOLBREEVI improves pulmonary gas transfer, quality of life, and the clinical symptoms associated with this rare and debilitating lung disease.” said CEO Matt Pauls.
