Cavion is a clinical-stage pharmaceutical company with an innovative mindset and compassionate culture.  Cavion closed a Series A venture capital financing in late 2016. Combining those investors’ industry capabilities with Cavion’s science and expertise has put us well on the road to developing our promising Cav3 modulators for movement disorders and rare, pediatric epilepsies. Committed to putting people in the center, Cavion’s first neurology clinical trial – the T-CALM trial of CX-8998 in essential tremor – is now recruiting subjects.
