“Pat is an exceptional addition to our executive leadership team and he will be a huge asset for us as we transform MannKind into a world class company,” Castagna said in a statement. “I expect Pat will help us to accelerate the growth of Afrezza and pipeline products to come, and position our company to deliver strong results in the years ahead.”
