Final Study Results are Expected in First Half of 2023
TARRYTOWN, NY, Nov. 08, 2022 (GLOBE NEWSWIRE) -- via NewMediaWire – PaxMedica, Inc. (Nasdaq: PXMD), a clinical stage biopharmaceutical company focusing on the development of anti-purinergic drug therapies for the treatment of disorders with intractable neurologic symptoms, today announced that it has initiated a Phase 3 trial, HAT-301, as part of its strategic plan to obtain US market approval of PAX-101 (intravenous suramin).
The Phase 3 HAT-301 trial is a pivotal, retrospective, controlled analysis of suramin for the treatment of the rare and fatal tropical disease, Stage 1 Trypanosoma Brucei Rhodesiense Human African Trypanosomiasis (Stage 1 TBR HAT). The study is underway at multiple primary HAT treatment sites in Uganda and Malawi. The Phase 3 trial is using exclusively licensed, retrospective clinical data that will be reviewed and compared with a natural history controlled dataset comprised of exclusively licensed source data.
The primary objective of the study is to demonstrate that the standard of care treatment using suramin, as currently practiced in Uganda and Malawi, leads to better clinical outcomes in patients with Stage 1 TBR HAT than observed in an untreated natural history cohort, that had documented illness prior to availability of suramin. The World Health Organization lists suramin, discovered in 1916, and found to be effective against Stage 1 HAT since at least 1920, as a standard of care for Trypanosoma b. Rhodesiense.
Howard Weisman, Chief Executive Officer of PaxMedica, commented, “We’re excited to have launched this critical study that, if successful, is an important milestone for the submission of a New Drug Application (NDA) for PAX-101 to treat the rare tropical disease, HAT. This is an important part of PaxMedica’s strategy that we believe is the fastest route to funding widespread clinical testing of suramin in autism spectrum disorder and other neurological conditions that lack effective treatments. We look forward to reviewing the final results of the study, which are expected in the first half of 2023.”
PaxMedica has formally met with the FDA three times to review the Phase 3 clinical trial plan. The study has the potential to serve as the pivotal efficacy component of an NDA. If an NDA for PAX-101 in HAT is approved, PaxMedica may be eligible to receive a priority review voucher from the FDA, which can be redeemed by the Company for priority review in a subsequent marketing application or potentially monetized by transferring the voucher to a third party.
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 compound, 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.
