Pharnext Pharmaceuticals, a clinical-stage biopharmaceutical company, partnered with HNF in 2012 to support the development of PXT3003.
PXT3003 is a novel combination drug of baclofen, naltrexone, and sorbitol designed to downregulate the overexpression of PMP22, the protein impacted in CMT1A. This leads to the improvement of neuronal signaling in dysfunctional peripheral nerves.
Results of their pivotal phase III are expected by Q4, 2023.
“GRIN data has been essential in clinical trial protocol design, site selection, and efficient patient recruitment for the pivotal Phase III clinical study of our lead asset PXT3003, the PREMIER trial, in development for the most common type of CMT, CMT1A. In addition, the robust data collected in GRIN, together with the ongoing CMT&Me digital survey, will enable a better understanding of the burden of disease, comorbidities, and critical patient demographics as we move forward to a potential commercialization of PXT3003 if approved by the FDA. Topline data of the PREMIER trial are expected in the last quarter of 2023.” Xavier Paoli M.Sc. Pharnext, Chief Operating Officer

Building Awareness on CMT and Supporting the Patient Community – HNF Announces Support from Pharnext
HNFpharnext recently entered into a partnership with the French biopharmaceutical company, Pharnext, to help raise awareness of Charcot-Marie-Tooth (CMT) disease and support the CMT patient community through several initiatives. Building awareness is key! Pharnext’s support will assist HNF in distributing HNF’s CMT Update quarterly newsletter, enhancing the Global Registry for Inherited Neuropathies (GRIN), setting up activities for CMT September Awareness Month in the US and strengthening the CMT Inspire Community.
Targeting PMP22 in CMT1A Patients with Gene Duplication
In previous collaborative work with a group of investigators including Dr Rolf Renne from the University of Florida, Dr. Alex Murashov from East Carolina University and Dr. Lynn Hudson from the NIH-NINDS, we validated a microRNA known as miR29a as a reagent that corrected the expression level of PMP22 in rodent Schwann cells.
