Why it matters

Fragile X syndrome is the most common genetic cause of autism spectrum disorder, affecting approximately 1 in 7,000 males and 1 in 11,000 females globally. Currently, there are no approved treatments for this condition. Therefore, KER-0193 offers a promising new option for patients with unmet needs. The drug has already cleared a phase I clinical trial and holds Orphan Drug and Rare Pediatric Drug designations from the US Food and Drug Administration (FDA).

What’s next

The acquisition will enable Servier to advance KER-0193 into phase II trials in the US and Europe next year. This move is part of Servier’s broader strategy to establish a differentiated pipeline of innovative therapies. The company aims to address underserved needs in neurology, particularly focusing on rare diseases. For further insights into Servier’s strategic initiatives, visit our insights section.
