- Introduction: Cladribine is a deoxyadenosine analogue prodrug that induces immune reconstitution by selectively targeting B- and T-lymphocytes. Cladribine tablets (CladT) are administered in two courses, 12 months apart, for patients with relapsing multiple sclerosis (RMS). Post-marketing surveillance is important for evaluation of long-term safety and effectiveness in a real-world setting. CLADCOMS (CLADribine tablets long-term Control Of MS) is a post-marketing investigator driven study. Here we report two year prospectively obtained data on the first 100 patients included in the study until April 2021.Objectives/Aims: To investigate number of patients free of disease activity until April 2023 among the first 100 RMS patients included.Methods: CLADCOMS includes patients with RMS from eight academic neurology clinics of Sweden starting Cladribine treatment after 23rd of March 2018. Data was prospectively registered in the Swedish Neuroregistry using highly structured yearly follow-up routines. Descriptive data on relapses, MRI activity, and Patient Reported Outcome Measures from the first 100 patient included in the study were obtained from the registry.Results: By April 2023, 206 patients were included in the CLADCOMS study. In April 2021 the first 100 patients had entered the study including 30% treatment naïve, 26% switched from natalizumab, 10% from dimethyl fumarate and 7% from rituximab. After the first two years after treatment initiation 87% were relapse free. MRI-activity during the first two years after treatment initiation will be analyzed.Analysis of CD19+ B-cells counts over time showed a significant drop from baseline before first dose (0.38x109/L ±0.68) to year one (0.15x109/L ±0.12) and year two (0.13x109/L ±0.09). The proportion of memory B-cells dropped from 11.8% ±9.33% at baseline to 3.0% ±2.8% after the first year and to 2.6% ±2.4% after the second year of treatment. The proportions of naïve B-cells raised over time from 61% ±18.3% at baseline to 76.8% ±18.7 year one and 78.6% ±12.3 after two years of treatment.Conclusion: CladT treatment demonstrates clinical stability during the first two years after treatment initiation. The unique immune depletion helps to explain the durability of effects of Cladribine. However, continued follow-up is needed to assess the effectiveness and safety of treatment with Cladribine to investigate time to disease re-activation after full treatment.
