Primary Outcome(s)
Main Objective: The primary objective of this study is to assess whether rituximab is effective in CIDP permitting to suspend immunoglobulin therapy without clinical worsening
Primary end point(s): To determine the efficacy of rituximab compared to placebo in reducing the proportion of patients with CIDP who worsen by at least one point in the INCAT score or two-points in the MRC sum-score or four points in the R-ODS score within six months after suspension of the treatment with immunoglobulins
Secondary Objective:
The secondary objective is to evaluate whether treatment with rituximab may improve the response to therapy compared to placebo in patients treated with immunoglobulins and whether it may allow delay of the mean worsening time after discontinuation of immunoglobulin therapy. The exploratory objectives are the correlation between the response to rituximab therapy and the clinical form of CIDP and the presence of antibody reactivity against Ranvier node antigens.
Timepoint(s) of evaluation of this end point: The primary endpoint will be evaluated at month 12 after the start of treatment with rituximab
Secondary Outcome(s)
Secondary end point(s): To determine whether the treatment with rituximab to IVIg or SCIg in patients with CIDP may improve the disability (INCAT score and R-ODS score) and impairment (MRC sums-core for muscle strength) compared to placebo; To determine the efficacy of rituximab compared to placebo in reducing the number of patients with CIDP who worsen by at least one point in the INCAT score, two-points in the MRC sum-score or four points in the R-ODS score within 12 months and 18 months after suspension of the treatment with immunoglobulins; To determine the proportion of patients who suspend the treatment with rituximab or placebo for adverse events or for voluntary reasons or who develop adverse events in the 12 months following the start of treatment with rituximab; To compare the mean time for patients with CIDP treated with rituximab or placebo to worsen by at least one point in the INCAT score, two-points in the MRC sum-score or four points in the R-ODS score after suspension of the treatment with immunoglobulins; To determine whether the association of rituximab to IVIg or SCIg in patients with CIDP may improve compared to placebo the quality of life of the patients determined by SF-36 score after 6, 12, 18 and 24 months from the start of treatment with rituximab; Exploratory endpoint: To determine the difference between patients treated with rituximab or placebo in the mean variation of motor conduction block, negative distal CMAP amplitude, motor conduction velocity, distal and F-wave latencies in the two most relevant nerve between at the baseline and months 6, 12 and 24.; Exploratory endpoints: - To correlate the response to therapy with rituximab with the clinical form of typical or atypical CIDP - To correlate the response to therapy with rituximab in patients with CIDP with the presence of antibody reactivities against proteins at the node of Ranvier (contactin 1 and neurofascin 155)
Timepoint(s) of evaluation of this end point: After 6, 12, 18 and 24 months from the start of treatment with rituximab; The endpoint will be evaluated at months 18 and 24 after the start of treatment with rituximab; The endpoint will be assessed during the 12 months following the start of treatment with rituximab; The endpoint will be evaluated after 12 months from the start of treatment with rituximab; The endpoint will be evaluated after 6, 12, 18 and 24 months from the start of treatment with rituximab; The endpoint will be assessed at months 6,12 and 24 after the visit at the screening; The endpoints will be evaluated at the end of the study
