Condition steroid-refractory chronic gvhd
Treatment rituximab
Phase phase 2
Target CD20
Sponsor The Korean Society of Hematopoietic Stem Cell Transplantation
Collaborator Hoffmann-La Roche
Start date May 2007
End date May 2008
Trial size 42 participants
Trial identifier NCT00472225, KHSCT-01-2007


Chronic GVHD is the most common late complication following allogeneic stem cell transplantation. It has features resembling autoimmune disorders such as scleroderma, primary biliary cirrhosis, bronchiolitis obliterans, chronic immunodeficiency etc. Thus, chronic GVHD can lead to debilitating complications such as joint contractures, blindness, end-stage lung disease, etc so that chronic GVHD has a major impact both on survival as well as quality of life. Although its pathogenesis is still poorly unclear, it has been reported since 2000 that B cell-mediated immunity may also contribute to development of chronic GVHD other than T cells. Thus, targeting against B cell may be a useful treatment strategy in the treatment of chronic GVHD.

The purpose of this study is to determine whether rituximab, an anti-CD20 monoclonal kimeric antibody is effective in the treatment of chronic graft-versus-host disease (chronic GVHD) refractory to steroid.

Study Design

Allocation non-randomized
Endpoint classification efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
Rituximab treatment arm
rituximab Mabthera
Rituximab Induction: Rituximab 375 mg/m2 weekly IV for 4 consecutive weeks Rituximab Maintenance: Rituximab 375 mg/m2 monthly IV for 4 consecutive months

Primary Outcomes

Complete response (CR) : Resolution of all signs and symptoms of chronic GVHD Partial response (PR) : Improvement (at least 1 clinical score reduction) in 1 or more organs of involvement and no evidence of worsening in any organ
time frame: Response evaluation will be perfomed every 4 weeks during the maintenance of rituximab (the 12th, 16th, 20th, 24st, 36th and 52th week).

Secondary Outcomes

Steroid tapering
time frame: Within one year after start the first dose of rituximab
Quality of life
time frame: Baseline, the 8th and 52th week.
time frame: 1 year

Male or female participants from 3 years up to 74 years old.

Inclusion Criteria: - All recipients underwent allogeneic stem cell transplantation for haematologic disorders - All recipients diagnosed as chronic GVHD according to diagnostic criteria proposed by National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic GVHD - The presence of one diagnostic sign Or - The presence of one distinctive sign (Appendix 1B) with laboratory or histopathologic confirmation in the same or other organ if diagnostic feature is not present - All patients with chronic GVHD have at least moderate score based on the global scoring system of chronic GVHD - Recipients refractory or resistant to therapy with corticosteroid - Patients had chronic GVHD with the same severity during the last one month while they had received the equivalent of prednisone ≥0.5mg/kg per day or 1mg/kg every other day at least for 30 days or longer - Informed consent - Other concomitant medication - Patients treated with other immunosuppressive agents (cyclosporine, thalidomide etc) as a combination therapy with corticosteroid must be receiving a dosage that has been stable for at least 1 month prior to screening. Exclusion Criteria: - Recipients received donor lymphocyte infusions in the preceding 100 days - Serious comorbid diseases - Life expectancy of less than 1 month - Age < 2 years and > 75 years - Pregnant or intended to become pregnant - Concomitant administration of any other experimental drug under investigation, or concomitant chemotherapy, hormonal therapy, or immunotherapy
