MYPAN is a research study. In this study we want to see if a medicine called Mycophenolate mofetil (MMF) is as good as the normal medicine doctors use for vasculitis called cyclophosphamide (CYC).

MYPAN is an international trial that will be conducted in several countries including the United Kingdom, Belgium, Croatia, Czech Republic, Germany, Greece, Italy, Netherlands, Portugal, France, Spain, Sweden and Turkey.
