Clear Scientific is pioneering a new paradigm for treatment of conditions and diseases that involve an excess of specific compounds in the body. The company is developing highly selective, small molecule sequestrants that bind, inactivate, and rapidly clear these excess compounds from the body. Clear Scientific receives funding from the National Institutes of Health (NIH) / National Institute on Drug Abuse (NIDA) and is working with their network of medical and academic professionals.
About CS-1103:
CS-1103 is a first-in-class injectable small molecule sequestrant that binds and inactivates target compounds, rapidly reversing their effects and accelerating their clearance into urine. The Company is initially targeting methamphetamine, fentanyl and cocaine overdose, representing close to 95% of the drug fatalities in the US. Clear Scientific’s pipeline includes indications in central nervous system (CNS), metabolic diseases, amongst others.
