In 2006, Dave Boule was diagnosed with polycythemia vera, a type of myeloproliferative neoplasm (MPN) that affects blood cell production in the body. After starting phlebotomy treatment, his platelets and red blood cell counts continued to rise, and he started doing research into other options for therapies that might be more effective. This research led him to Dr. Richard T. Silver at Weill Cornell Medicine.
