First trial of gene therapy for serious pain very successful, moves quickly to phase 2 at U of Michigan

  [ 15 votes ]   [ Discuss This Article ] • April 19, 2011

This gene, delivered via injected viral DNA, is taken up by the nervous system & produces a natural opioid in the target pain pathway.

In the first clinical trial of gene therapy for treatment of intractable pain, researchers at the University of Michigan Department of Neurology observed that the treatment appears to provide substantial pain relief.

In a study published online by the Annals of Neurology, the researchers showed that the novel agent NP2 is safe and well-tolerated. In addition, measures of pain in the treated patients suggested that NP2 may provide a substantial analgesic effect.

NP2 is a gene transfer vector that expresses the opioid peptide enkephalin (naturally released by neurons in the central nervous system & adrenal gland).

In preclinical work in animals, a team led by Dr. David Fink, MD, chair of the Department of Neurology, had demonstrated that injection of NP2 into the skin reduces pain in models of pain caused by nerve damage, inflammation, or cancer.

In the clinical trial, 10 patients with unrelenting pain caused by cancer were injected with the gene transfer agent in the area of skin related to the location of pain.

"The concept underlying this therapeutic approach is that injection of NP2 into the skin results in uptake into the nervous system and the production and release of a pain-relieving chemical in a controlled site in the pain pathway," says Dr. Fink.

"In the study, patients who received the low dose of vector showed little reduction in pain; patients receiving the higher doses showed a greater than 80% reduction in pain over the course of 4 weeks following treatment."

Product of 20 Years’ Research

Dr. Fink's laboratory has been working on the use of modified Herpes simplex virus-based vectors that are taken up by sensory nerves following skin injection to develop therapies for diseases of the nervous system for more than 20 years.

Patents related to this technology have been exclusively licensed by Diamyd Medical, a publicly-traded Swedish biotechnology company that sponsored the trial, and the human-grade vector NP2 was produced by Diamyd, Inc, the US subsidiary of Diamyd Medical.

The recombinant replication defective HSV approach represents a platform technology – a nerve targeting drug delivery system (NTDDS) - that can be used to deliver and express any one of a number of genes in the nervous system.

A related NTDDS vector, NG2 reduces pain-related behaviors in preclinical models of neuropathic pain from nerve injury and diabetes.

NTDDS gene transfer to the DRG to express neurotrophins locally prevents the progression of polyneuropathy in relevant preclinical models, suggesting that the NTDDS platform may be used to treat degenerative polyneuropathies as well.

"This is an example of translational research in which we have moved from laboratory bench studies through animal models into new treatment that we are testing patients. There was no placebo control in this phase 1 study, but the apparent dose-dependent pain relief was encouraging to us," Dr. Fink says.

A phase 2 trial to compare NP2 to a placebo control has already been initiated under sponsorship from Diamyd.
