Collaboration Will Investigate a Next Generation Orally Delivered Anti-Purinergic Compound
Proof-of-Concept Study Based on one of PaxMedica’s Proprietary Pipeline Candidates
TARRYTOWN, NY, June 08, 2023 (GLOBE NEWSWIRE) -- via NewMediaWire – PaxMedica, Inc. (Nasdaq: PXMD), a clinical stage biopharmaceutical company focusing on the development of novel anti-purinergic drug therapies (APT) for the treatment of Autism Spectrum Disorder (ASD) and other serious conditions with intractable neurologic symptoms, today announced that it has entered into an agreement with PoloMar Health to investigate the use of emodin in a clinical program as a potential treatment for patients with autism spectrum disorder.
Emodin is an orally bioavailable selective P2X7 inhibitor, and is currently available as a component in a number of over-the-counter nutritional supplements. Emodin is a naturally occurring substance that is found in several plants, including rhubarb and Japanese knotweed. PoloMar Health is also working in partnership with The BRAIN Foundation on this initiative.
Under the agreement, PoloMar Health will retain rights to develop and commercialize any non-prescription supplement form of the product, while PaxMedica will retain exclusive rights to develop and commercialize a highly purified form of emodin as a prescription pharmaceutical product following FDA and other regulatory authorities’ guidance. In 2019, PaxMedica completed several in vivo animal studies in a mouse model of autism and demonstrated positive results for emodin in several measures of cognition, memory, and behavior. These findings were the basis of a patent filing that was initiated that same year by PaxMedica.
A Phase II proof-of-concept trial, using a proprietary, highly bioavailable form of emodin in patients with ASD, is anticipated to begin in Q2 of 2023. PoloMar Health will be the sponsor of the U.S.-based study, and will, along with The BRAIN Foundation, provide the funding for the study. Depending on the outcome of this study, PaxMedica may pursue a formal development program for a potential prescription-grade product to treat patients with ASD.
“This valuable collaboration with PoloMar Health and the BRAIN Foundation is expected to enable PaxMedica to cost-effectively advance an existing asset in our pre-clinical pipeline, while maintaining our unwavering focus and commitment to the development and future approval of our primary clinical pipeline product, PAX-101. Moreover, as a selective P2X7 purine receptor inhibitor, emodin will extend our overall knowledge of these types of agents in the treatment of the core symptoms of autism,” said Howard Weisman, Chief Executive Officer of PaxMedica.
About PaxMedica
PaxMedica is a clinical stage biopharmaceutical company focusing on the development of anti-purinergic drug therapies (“APT”) for the treatment of disorders with intractable neurologic symptoms, ranging from neurodevelopmental disorders, including Autism Spectrum Disorder (“ASD”), to Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (“ME/CFS”), a debilitating physical and cognitive disorder believed to be viral in origin and now with rising incidence globally due to the long term effects of SARS-CoV-2 (“COVID-19”). One of PaxMedica’s primary points of focus is the development and testing of its lead program, PAX-101, an intravenous formulation of suramin, in the treatment of ASD and the advancement of the clinical understanding of using that agent against other disorders such as ME/CFS and Long COVID-19 Syndrome, a clinical diagnosis in individuals who have been previously infected with COVID-19.
