Bright Minds Biosciences' stock surged over 1,500% due to Lundbeck's $2.6 billion acquisition of Longboard Pharmaceuticals, whose lead asset, bexicaserin, targets 5-HT2C receptors. Bright Minds' BMB-101, also a 5-HT2C agonist for DEEs, initiated its Phase 2 study last month, positioning it similarly to Longboard.
