- Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the death of motor neurons that leads to progressive muscle weakness and difficulties in speaking, swallowing, and breathing.
- Riluzole prolongs survival and time to tracheostomy in patients with ALS via a number of potential mechanisms, including reduction of glutamate excitotoxicity.
- Riluzole can cause dose-related abnormalities in liver function tests.
- Approximately 50% of patients receiving riluzole oral tablets experience elevated alanine transaminase (ALT) levels, with 8% above 3 x upper limit of normal (ULN) and 2% above 5 x ULN.
- BHV-0223 is a novel investigational 40 mg sublingually dissolving Zydis® formulation of riluzole that is bioequivalent to the riluzole 50 mg oral tablet formulation.
- Because of its sublingual route of administration, BHV-0223 bypasses first-pass metabolism, achieving adequate drug concentrations with diminished drug burden and potentially less risk of liver toxicity.
- DILIsym® (DILIsym Services, Inc, Research Triangle Park, NC) is a validated multi-scale computational model that supports evaluation of liver toxicity risks
