"We have learned a lot since the early studies in mice - not just about how BCG works but also about its potential therapeutic benefits, similar to what are being seen in trials against other autoimmune diseases," says Faustman. "We are so grateful to all of the donors, large and small, who have made this trial possible - especially the Iacocca Foundation, which has believed in us and has been a supporter since our early days. Our goal is to complete enrollment and also to raise the remaining funds needed for the trial by the end of this year."
A generic drug with over 90 years of clinical use and safety data, BCG is currently approved by the FDA for vaccination againsttuberculosis and for the treatment of bladder cancer. The vaccine is known to elevate levels of the immune modulator tumornecrosis factor (TNF), which Faustman's team previously showed can temporarily eliminate in both humans and mice the abnormal white blood cells responsible for autoimmune type 1 diabetes. Increased TNF levels also stimulated production of protective regulatory T cells.
