Dupixent, co-developed with US-based Regeneron, received approval to treat patients with eosinophilic asthma and those dependent on anti-inflammatory steroids, Reuters said.
The drug acts by restraining proteins responsible for the inflammation of airways of the lungs, the root cause of asthma.
Dupixent was launched in the US in April 2017 for the treatment of moderate-to-severe eczema in adults.
The drug, a key revenue driver for Sanofi, had worldwide sales of 176 million euros ($202.5 million) in the second quarter of 2018, of which 151 million euros came from the US.
The drugmaker is also co-developing Dupixent for at least seven other conditions including pediatric asthma, chronic sinus infection with nasal polyps, and adolescent eczema.
