A Protocol Based Treatment for Debilitating Fibrosing Skin Disorders With (Anti-CD 20), Rituximab, Evaluating Safety and Efficacy

Phase 2

Completed

• Conditions: Debilitating Fibrosing Skin Disorders (Localised Scleroderma, Eosinophilic Fasciitis)
• Interventions: Drug: Rituximab

• Registration Number: NCT00936546
• Lead Sponsor: University Hospital, Ghent

Brief Summary

This study will evaluate the safety and efficacy of the combination of rituximab and methotrexate to treat disabling fibrosing skin disorders.Rituximab will be administered at baseline and month 6. The drug will be considered efficacious if the skin thickness diminishes substantially.

Exclusion Criteria

• FVC<, = 50%
• LVEF<, = 40% of predicted value,
• DLCO<, = 40% of predicted value
• Exclusion criteria as specifically described in the protocol for anti-CD-20:
• Lack of peripheral venous access.
• Pregnancy or breast feeding.
• Significant cardiac or pulmonary disease (including obstructive pulmonary disease).
• Evidence of significant uncontrolled concomitant disease such as, but not limited to, nervous system, renal, hepatic, endocrine or gastrointestinal disorders which, in the investigator's opinion, would preclude patient participation.
• Primary or secondary immunodeficiency (history of, or currently active), including known history of HIV infection.
• Known active infection of any kind (excluding fungal infections of mail beds), or any major episode of infection requiring hospitalization or treatment with i.v. anti-infectives within 4 weeks of baseline or completion of oral anti-infectives within 2 weeks prior to baseline.
• History of deep space/tissue infection (e.g. fasciitis, abscess, osteomyelitis) within 52 weeks prior to baseline.
• History of serious recurrent or chronic infection (for screening for a chest infection a chest radiograph will be performed at screening if not performed within 12 weeks prior to screening).
• History of cancer, including solid tumors, hematologic malignancies and carcinoma in situ (except basal cell and squamous cell carcinoma of the skin that have been excised and cured).
• History of a severe allergic or anaphylactic reaction to a biologic agent or known hypersensitivity to any component of rituximab or to murine proteins.
• Concurrent treatment with any biologic agent or DMARD other than MTX. Treatment must be discontinued 14 days prior to baseline , except for the following: azathioprine for ≥ 28 days; leflunomide for ≥ 8 weeks (or ≥ 14 days after 11 days of standard cholestyramine or activated charcoal washout); infliximab ≥ 8 weeks; adalimumab ≥ weeks.
• Previous treatment with > 1 biological agent.
• Treatment with any investigational agent within 28 days of baseline or 5 half-lives of the investigational drug (which ever is the longer).
• Receipt of any vaccine within 28 days prior to baseline
• Intolerance or contraindications to i.v. glucocorticoids.
• Positive serum human chorionic gonadotropin (hCG) measured at screening or a positive pregnancy test prior to the first rituximab infusion.
• Positive tests for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb) or hepatitis C serology.
• Hemoglobin < 8.0 g/dL.
• Concentrations of serum IgG and/or IgM below 5.0 and 0.40 mg/mL, respectively.
• Absolute neutrophil count (ANC) < 1.5 X 10³/µL.
