Aspreva Pharmaceuticals believes that bad aim can be a good thing when treating diseases. This company conducts clinical trials to find new uses for approved drugs. As a result, partners team up with Aspreva to gain incremental revenue from the commercialization of the new version of the drug. Working in collaboration with Roche, Aspreva conducts clinical trials to investigate the use of Roche's CellCept (indicated for prevention of rejection in organ transplant patients) to treat autoimmune diseases including lupus nephritis and pemphigus vulgaris. Aspreva is a subsidiary of Swiss pharmaceutical firm Galenica Group.
