Soleno Therapeutics Pulls Europe Drug Filing After $2.9 Billion Neurocrine Deal
Soleno Therapeutics withdrew its European filing for VIOKAT on Tuesday, halting a regulatory review that was expected to conclude in 2026. The move came one day after Neurocrine Biosciences agreed to acquire Soleno for $2.9 billion in cash, or $53 a share. Vykat XR, Soleno’s only marketed product, generated $190.4 million in 2025 U.S. sales. Neurocrine said it has no immediate plans for a European launch.
