DTx Pharma Research Update

The CMT Research Foundation is currently funding a research project led by DTx Pharma to design genetic therapies for Charcot-Marie-Tooth disease (CMT). By attaching the genetic sequences to molecules called long chain fatty acids, they allow the therapies to target cells in the nerves at much lower concentrations than traditional approaches. This is important in gene therapy because higher concentrations can cause dangerous immune system reactions. Although this research is still in preliminary stages — only being tested in cells and animals at this time — this approach, if successful, may overcome a fundamental hurdle in using gene therapies for peripheral nerve disease.

Most recently, the scientists at DTx Pharma have identified several genetic sequences that reduce the levels of PMP22 in animal models of CMT1A. One in particular was especially effective at lowering PMP22 and showed no signs of an immune response. Further testing and refinement is now underway to select the best candidates to take forward in development. Additionally, the researchers at DTx have been awarded a grant from the National Institutes of Health that effectively quadruples the initial CMT Research Foundation investment.
