Resumen
Fecha de inicio: 1 de julio de 1996
Fecha en la que se inscribió al primer participante.PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients are stratified according to investigational site and number of fistulae (single vs multiple). Patients are randomized to one of three treatment arms: Arm I: Patients receive an infusion of chimeric monoclonal antibody (cA2) on weeks 0, 2, and 6. Arm II: Patients receive an infusion of cA2 on weeks 0 and 2, and an infusion of placebo on week 6. Arm III: Patients receive an infusion of placebo on day 1 of weeks 0, 2, and 6. Patients are followed every month for 3 months, then every 6-12 months for up to 2 years.
