Coley's Toxins

What is Coley's Toxins?

Coley's Toxins, also known as mixed bacterial vaccines, is a mixture of killed bacteria from the species Streptococcus pyogenes and Serratia marcescens designed to trigger an infection-like reaction with a fever and subsequent immune response creating anti-cancer activity. William B. Coley, MD combined other ingredients such as exotoxins, endotoxins, enzymes, and other proteins, and administered his therapy several times weekly over several months. Any variations of Coley's Toxins produced today consist of different combinations of ingredients instead of one standard formula.

What are the potential benefits of Coley's Toxins?

The potential benefits associated with Coley's Toxins include an immune response and anti-cancer activity. Dr. Coley's research indicated that the anti-cancer response he observed in patients originated from the toxins in his formula and the body's reaction to the toxins. Studies by Dr. Coley and other researchers suggest that some types of cancer are more susceptible to anti-cancer activity from Coley's Toxins than others.

What is the history of Coley's Toxins?

Coley's Toxins was developed by William B. Coley, MD at Memorial Hospital in New York City in the 1890s. Dr. Coley is sometimes credited as being the first to recognize the potential role of the immune system against cancer.
