Description

Pralnacasan is a potent, non-peptide inhibitor of interleukin-1beta converting enzyme (ICE, aka Caspase-1). It was originally discovered by Vertex Pharmaceuticals and licensed for development to Aventis Pharma. In 2003 Aventis and Vertex Pharmaceuticals agreed to voluntarily discontinue development based on results from a 9-month animal toxicity trial that showed liver abnormalities due to chronic high doses of pralnacasan. Pralnacasan has also been investigated for the treatment of Partial Epilepsy; advancing to Phase II clinical trials.

Sample Use Guides

In Vivo Use Guide
In a Phase-IIa clinical trial patients suffering from rheumatoid arthritis received up to 1200 mg/day orally of pralnacasan for 12 weeks. Patients receiving 1200 mg/day had statistically significant reductions in the inflammatory biomarkers C-reactive protein, erythrocyte sedimentation rate, and serum amyloid A. PAtients receiving pralnacasan were also able to reduce their concomitant corticosteroid therapy.
