Product Information:

VX 765, is designed to inhibit Caspase, which is an enzyme that controls the generation of two cytokines, IL-1b and IL-18. VX-765 has been shown to inhibit acute seizures in preclinical models. In addition, VX-765 has shown activity in preclinical models of chronic epilepsy. VX-765 had been dosed in over 100 patients in phase-I and phase-IIa clinical trials relating to other diseases, including a 28-day phase-IIa clinical trial in patients with psoriasis. It has completed the treatment phase of a phase-IIa clinical trial of VX-765 that enrolled approximately 75 patients with treatment-resistant epilepsy. The double-blind, randomized, placebo-controlled clinical trial was designed to evaluate the safety, tolerability and clinical activity of VX-765.

In Vivo:

Belnacasan reduces inflammatory response in murine models of inflammatory disease.

Belnacasan (50-200 mg/kg) significantly reduces serum IL-1β levels by as much as 60%. It is noteworthy that the effect of Belnacasan on the release of IL-1β induced by LPS reached a plateau at 100 mg/kg. Belnacasan (25-100 mg/kg × 2) significantly reduces ear edema. Belnacasan also dose-dependently reduces the concentrations of cytokines, chemokines, and inflammatory mediators in the ear biopsy samples.

Belnacasan (25-200 mg/kg) significantly delays the time to seizure onset by 1.5- to twofold (p<0.01), reduces the number of seizures by 40% (p<0.01) and the total time spent in EEG seizure activity by 30 to 50% (p<0.01).
