About Dragonfly
We harness the power of the immune system to fight disease
Our Mission
Our mission is to revolutionize disease treatment by inventing therapies that harness the body's immune system for vastly improved patient outcomes.
Dragonfly's therapies are designed to be potent as single agents as well as in treatment combinations with existing disease-targeting therapies – such as T cell treatments for cancer.
Our founders and Scientific Advisory Board are major figures in disease biology and immunology, and launched Dragonfly to harness the power of the immune system to provide breakthrough treatments for patients.
