New Collaboration with the University of North Carolina at Chapel Hill and The Jackson Laboratory Addresses Charcot-MarieTooth/Inherited Neuropathy Mutations Using Gene Therapy

by | Apr 24, 2017 | 3 comments

Gene therapy represents an exciting new frontier being explored for treating a number of diseases. Currently, gene therapy is being used in a clinical trial to treat one of the rare forms of inherited neuropathy (IN), giant axonal neuropathy (GAN). Because of the potential gene therapy holds for treating a range of CMT/IN mutations-including the rarer ones—HNF is excited to announce a collaboration with the University of North Carolina at Chapel Hill and The Jackson Laboratory to begin the development of gene therapy approaches for Charcot-Marie-Tooth (CMT) and Inherited Neuropathies (IN). 

To start, our initial gene therapy work will focus on CMT type 6, which is caused by a recessive mutation in the C12orf65 gene and for which there is currently no treatment. CMT type 6 presents in patients with many of the typical symptoms associated with most types of CMT, but usually includes additional, significant impacts on vision and breathing that further challenge a patient’s quality of life.  And, unlike other forms of CMT, CMT type 6 is ultimately fatal. 

The CMT type 6 research that HNF is funding aims to replace the nonfunctional gene with a working copy.  Dr. Robert Burgess, lead co-investigator for this project, has developed a CMT type 6 mouse model to conduct a proof of concept study to determine the viability of using this approach to treat the disease. Dr. Steven Gray, assistant professor at the University of North Carolina, will be developing the gene therapy vector to be tested using this unique mouse model.  We are pleased to have Dr. Gray on this project’s team as his previous work was responsible for bringing the GAN gene therapy to a clinical trial.  Ensuring the success of this gene therapy approach will depend on getting everyone—health care providers and  CMT type 6 patients and their families— involved! Besides the work in the CMT type 6 mouse, patient specimens are extremely valuable for research. HNF will need to obtain skin fibroblasts from CMT type 6 patients that have a confirmed diagnosis. HNF will rely on its Centers of Excellence network and other medical institutions to obtain the skin fibroblasts needed to be sent to The Jackson Laboratory for further testing. 

Advancing a research project like this is a major undertaking requiring significant human, physical, and financial resources— however, the possibilities of achieving significant outcomes are unprecedented. To secure the ability of this project’s momentum, HNF has launched the Gene Therapy Fund to support this project’s efforts to tackle additional types of CMT/IN that warrant a gene therapy approach to treat CMT. The Gene Therapy Fund will be used and supported with the collaboration of Lori Sames (co-founder of Hannah’s Hope Fund and the tireless champion of the first gene therapy ever used for any  form of IN), UNC and The Jackson Laboratory.

We need your help! Here’s how to get involved: I support gene therapy research, and I want to enroll as a patient! If you are a patient with CMT and want to be part of this new initiative, please join the Global Registry for Inherited Neuropathies (GRIN).

Double Your Donation

Corporate matching gift programs are charitable giving programs setup by corporations in which the company matches donations made by employees to eligible nonprofit organizations. For example, if a donor works for Bank of America and donates $100 to the Hereditary Neuropathy Foundation, Bank of America will double the donation by also writing a check for $100.

Accelerating Patient Access to Investigational Drugs in 2015

Currently the FDA is working to update the process for physicians applying for accelerated patient access to investigational drugs, while the drug or biological product is being tested in clinical trials. This will also be important for the CMT community as clinical trials for this disease are being launched.

Do You Have Charcot-Marie-Tooth Type 4 (CMT4)? – We Need Your Help

Autosomal recessive demyelinating CMT4 patients present with earlyonset and slowly progressing symptoms. These include progressive distally accentuated weakness and atrophy of muscles in the lower limbs. In addition, patients may have weakness and atrophy of hands, sensory loss and pes cavus (high-arched feet), and walking difficulties. Further information on CMT4 can be found at Orphanet.

Hot Off the Press – Potential Treatment for CMT1A

Two recent publications from Pharnext describe a novel synergistic combination of 3 drugs (baclofen, naltrexone and sorbitol) and its effect on CMT1A both in the lab and in a phase II clinical trial. These 3 drugs already approved but for unrelated conditions, are combined at new optimal lower doses and under a new formulation. This novel potential therapeutic is called PXT-3003.

    I have CMT but not sure what level. I live in the Raleigh, NC area and would be interested in trial at UNC. I have issues with atrophy in my lower legs, hands and vision.

    I have cmt 1b and live near Chapel Hill. I lead a large group of individuals with cmt. Great news!

    I have CMT, but do not know what type. I wear a brace for drop foot on my left leg. My left leg is significantl smaller than my right leg. I also have significant balance issues. I cannot stand on my toes and I walk on the heels of both feet.

    I would like to have my mutation considered. I am 75 year of age and first noticed symptoms about fifteen years ago when I first noticed that I was unable to stand on my toes.

    I would like to participate in the clinical trial if possible.
