Rimonabant
We have an ongoing clinical development program with rimonabant aimed at treating fatigue, both physical and mental, and improving ambulation, performance and quality of life in patients with Central Nervous System (CNS) diseases, such as spinal cord injury or stroke, and in patients with persistent COVID-19.
Rimonabant is an antagonist/inverse agonist of endocannabinoid receptors located predominantly in the CNS. This drug has a well-established safety profile and is being evaluated in clinical trials for its repositioning as a possible treatment for fatigue and related functional symptoms caused by various CNS disorders.
