Soticlestat
Soticlestat (TAK-935, OV-935) is an experimental anticonvulsant and cholesterol 24-hydroxylase inhibitor being investigated as a treatment for Dravet syndrome, Lennox–Gastaut syndrome, tuberous sclerosis complex, dup15q syndrome, and CDKL5 deficiency disorder.[1][2] The development rights to the drug were purchased by Takeda Pharmaceuticals from Ovid Therapeutics in 2021.[3]

Soticlestat was designated as an orphan drug by the FDA in 2017 for the treatment for both Dravet syndrome and Lennox–Gastaut syndrome.[4] In a phase 2 study called ELEKTRA, soticlestat was well tolerated and reduced seizure frequency in patients with Dravet syndrome and Lennox–Gastaut syndrome.[5]
Mechanism of action
Soticlestat functions by blocking cholesterol 24-hydroxylase (CH24H, also known as CYP46A1), an enzyme in the brain that converts cholesterol to the oxysterol 24S-hydroxycholesterol (24S-HC). Reduction of 24S-HC has been shown to reduce glutamatergic signaling, which reduces seizures.[1][2] Soticlestat may also have neuroprotective and anti-inflammatory properties via glial cell modulation.[2]
