Clene Inc. is a late clinical-stage biopharmaceutical company focused on improving mitochondrial health and protecting neuronal function to treat neurodegenerative diseases, including amyotrophic lateral sclerosis, Parkinson's disease, and multiple sclerosis. It specializes in the discovery, development, and commercialization of clean-surfaced nanotechnology (CSN) therapeutics. CNM-Au8, the lead asset, is a concentrated aqueous suspension of catalytically active, clean-surfaced, faceted gold nanocrystals. CNM-Au8’s mechanism of action targets mitochondrial dysfunction by catalyzing the production of nicotinamide adenine dinucleotide. Its CNM-ZnAg is a broad-spectrum antiviral, antibacterial agent comprised of zinc (Zn2+) and silver (Ag+) ions under development to treat infectious disease and to provide immune support for symptom resolution. Its CNM-AgZn17 is a gel polymer suspension of Zn2+ and Ag+ under development for the treatment of infectious diseases and to support wound healing.
