Non-Viral Gene Therapy Offers Hope for Pain Relief from Diabetic Neuropathy

PainRelief.com: What is the background for this study? Would you explain how VM202 is unique?

  • ResponseDiabetic peripheral neuropathy is one of the most common complications of diabetes and many of DPN patients suffer from severe pain that affects their daily activities and life quality. Though there are medications, both Rx and OTC drugs, used to ameliorate pains from diabetic peripheral neuropathy, many of them fall short of analgesic efficacy or often lead to not so trivial side effects. 
  • Engensis (VM202) is plasmid DNA therapy, non-viral gene therapy, which encodes hepatocyte growth factor (HGF) gene that is designed to simultaneously express two isoforms of HGF protein at high levels. HGF is known to have angiogenic and neurotrophic effects and, when expressed in the human body, induces formation of new micro vessels and nerve regeneration through remyelination and axon outgrowth, resulting in improvement in peripheral neuropathy condition. Engensis does not integrate into the human genome.
  • Historically, our research first focused on therapeutic angiogenesis of HGF with a proof of concept research in critical limb ischemia, an extreme form of peripheral artery disease. In the process, we realized that Engensis would also be effective for peripheral neuropathy, and a coffee chat with the current PI, Dr. Kessler of Northwestern University, led to an idea of using Engensis in neurological diseases.
  • Throughout Phase 1 through 3 clinical trials for DPN in the US, Engensis has been observed safe and well-tolerated in patients, and, during the Phase 3 study, received RMAT (regenerative medicine advanced therapy) designation from the FDA.
