Gene Therapy for Chronic Pain Goes on Clinical Trial
Filed in archive Drugs, Vaccines and Therapeutics , Gene Therapy by ruth on September 16, 2008

In this groundbreaking clinical trial, the investigators will use a vector created from herpes simplex virus (HSV) - the virus that causes cold sores - to deliver the gene for enkephalin, one of the body's own natural pain relievers.
"In pre-clinical studies, we have found that HSV-mediated transfer of enkephalin can reduce chronic pain," says David Fink, M.D., Robert Brear Professor and chair of the department of neurology at the U-M Medical School. Fink developed the vector with collaborators and will direct the study.
The researchers are recruiting 12 patients with intractable pain from cancer for this study. For more information, contact the U-M Cancer AnswerLine, 800-865-1125.
