If someone could give you a vaccine that would cure your fibromyalgia, would you do it? That may sound like a dream, but it’s closer to reality than you might think. Los Angeles-based biomedical firm EpicGenetics and Massachusetts General Hospital researchers are seeking approval from the U.S. Food and Drug Administration (FDA) to conduct a clinical trial next year to test the Bacille Calmette-Guerin (BCG) vaccine as a potential treatment for fibromyalgia.
BCG is a generic tuberculosis vaccine that is almost a 100 years old and has been safely administered millions of times,” explained Dr. Denise Faustman, head of the Faustman Lab at Massachusetts General Hospital. “For over 10 years, our research group at Massachusetts General Hospital have been actively investigating the role that the BCG vaccine could play in treating various forms of autoimmunity. Our current focus is type 1 diabetes, but globally BCG is being tested in a number of autoimmune diseases. Over the next two years we will begin clinical testing of BCG in fibromyalgia.”
According to the World Health Organization, more than 100 million children are given the BCG vaccine each year. It’s mainly used in developing countries where tuberculosis is still active. The BCG vaccine is not available in the United States because of the low risk of infection. In the U.S., BCG is used in a small number of patients to treat bladder cancer.
So, the obvious question is why would a vaccine for an infectious lung condition be used for fibromyalgia? The answer lies within the immune system.
Vaccines are typically given to healthy people to prevent infection. In this case, however, the BCG vaccine would be administered to fibromyalgia patients in an effort to quell their symptoms.
When EpicGenetics was tasked with creating a diagnostic test for fibromyalgia several years ago, researchers ran all sorts of lab tests on fibromyalgia patients to figure out how they differed from healthy control subjects and what might be causing their symptoms. Researchers discovered several white blood cell abnormalities in fibromyalgia patients, leading them to conclude symptoms are associated with a suppressed immune system.
“We believe [the term] fibromyalgia is a misnomer,” said Dr. Bruce Gillis, EpicGenetics’ CEO. “These people aren’t suffering with anything that’s affecting the muscles, per say. What they are suffering with is their immune system cannot produce normal quantities of protective proteins. …There are cells in the immune system called peripheral blood mononuclear cells. They are not producing normal quantities of the protective proteins called chemokines and cytokines.”
