Abstract:
Objective To investigate the efficacy of anti-CD25 monoclonal antibody for steroid-refractory acute graft-versus-host disease (SR-aGVHD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients.Methods A total of 80 patients with SR-aGVHD from January 1st 2012 to December 31st 2016 were enrolled in this study.Acute GVHD were classified as classic aGVHD (n=72) and late-onset aGVHD (n=8).Anti-CD25 monoclonal antibodys (mAb) were administrated on days 1,4,8,15,and 22.The efficacy of anti-CD25 mAb was evaluated at day 28 after the initial treatment.The associated factors of clinical outcome were analyzed.Results The overall response (OR) rate of anti-CD25 mAb was 75％ (60/80),with complete response (CR) rate,partial response (PR) rate and no response(NR) rate 52.5％ (42/80),22.5％ (18/80),and 25％ (20/80),respectively.GVHD-relapse was not observed with a median follow-up time of 394.5 days (range,12-1 761 days).The 6-month overall survival (OS) rate was 68.4％ (95％CI 63.2％-73.6％).The 1-year OS rate was 63.1％ (95％CI 57.6％-68.6％),and 2-years OS rate was 50.7％ (95％CI 44.3％-57.1％).Non-relapse mortality (NRM) rate of 1 and 3 years was 32.6％ (95％CI 27.2％-38％) and 41.7％ (95％CI 35.3％-48.1％),respectively.The 1 and 2 years cumulative incidence of chronic graft versus host disease (cGVHD) was 32.9％ (95％CI 26.4％-39.4％) and 38.9％ (95％CI 31.8％-46.0％).By univariate and multivariate analysis,liver involvcment was an independent poor risk factor of SR-aGVHD (OR=4.66,95％ CI 1.145-18.962,P=0.032).Conclusion Anti-CD25 mAb serves as an alternative and effective salvage therapy for SR-aGVHD at present.Liver involvement is a predictive factor of poor response in patients with SR-aGVHD.
