In August 2015, Turing Pharmaceuticals and its then-chief executive, Martin Shkreli, purchased a drug called Daraprim and immediately raised its price more than 5,000 percent. Within days, Turing contacted Patient Services Inc., or PSI, a charity that helps people meet the insurance copayments on costly drugs. Turing wanted PSI to create a fund for patients with toxoplasmosis, a parasitic infection that is most often treated with Daraprim.
