At present, imitation EC-MPS have just come on the market, no clinical studies have confirmed the efficacy and safety of using imitation EC-MPS for immunosuppressive therapy after kidney transplantation. Therefore, there is an urgent need to conduct a multicenter study in China to provide further guidance for the use of imitated mycophenol sodium enteric-coated tablets in kidney transplant patients. Therefore, this study will analyze whether the anti-rejection effect of generic EC-MPS in the treatment of renal transplantation in Chinese population is equivalent to that of the original EC-MPS, in order to provide reference for clinical rational drug use.
