(OTCMKTS: RSPI) is a clinical-stage biopharmaceutical company focused on the discovery and development of small-molecule therapeutics for the treatment of central nervous system disorders. The company’s proprietary platform centers on positive allosteric modulators of the AMPA receptor, commonly known as ampakines, which are designed to enhance synaptic transmission and support neuronal function in a variety of neurological conditions. The company’s lead product candidates include CX717, CX1739 and CX1942, each of which is being evaluated for distinct indications such as opioid-induced respiratory depression, attention-deficit/hyperactivity disorder (ADHD) and cognitive impairment associated with aging or disease. Cortex has advanced these compounds through preclinical and early-stage clinical studies and has collaborated with pharmaceutical partners to explore broader therapeutic applications and formulation strategies. Founded in 1996 and headquartered in Irvine, California, Cortex Pharmaceuticals operates a research facility staffed by scientists with deep expertise in neuropharmacology and drug development. The management team brings together years of experience in advancing investigational therapies from discovery through clinical proof-of-concept, with the goal of addressing unmet medical needs in neurology. Cortex continues to refine its pipeline through strategic collaborations and internally driven research initiatives, seeking to translate its ampakine technology into safe and effective treatments that improve patient outcomes across multiple neurological indications.AI Generated.
