Company Profile

Clene Inc. is a biopharmaceutical firm in the clinical development phase, dedicated to the discovery, advancement, and market introduction of pioneering therapeutic agents utilizing clean-surfaced nanotechnology (CSN). CNM-Au8 stands as its flagship compound, currently under evaluation across a diverse range of clinical studies. This includes a pivotal Phase 2/3 study intended for regulatory submission in individuals battling amyotrophic lateral sclerosis (ALS). The company has successfully concluded a Phase 2 proof-of-concept trial for those with early manifestations of ALS. Furthermore, two open-label, investigator-blinded Phase 2 trials assessing brain energy metabolism have been finished. An ongoing Phase 2 trial is investigating CNM-Au8's potential to mitigate visual pathway deficits stemming from chronic optic neuropathy, aiming for remyelination in stable relapsing Multiple Sclerosis patients. A Phase 2 clinical investigation targeting Parkinson's Disease patients is also slated for commencement. Beyond its leading candidate, Clene's pipeline extends to include CNM-AgZn17. This gel formulation, comprising silver and zinc ions, is in development to combat infectious diseases and hasten wound recovery. Additionally, CNM-ZnAg acts as a broad-spectrum antiviral and antibacterial compound, designed to address various infectious conditions like COVID-19, while also offering immune support for symptom alleviation. For oncology, CNM-PtAu7 is a gold-platinum CSN therapeutic agent currently in development. The company also distributes dietary supplements, featuring rMetx, a liquid supplement containing zinc-silver ions, and KHC46, an aqueous gold supplement with trace amounts of gold nanoparticles.
