The management of multiple sclerosis (MS) has seen significant advancements, particularly with the introduction of oral disease-modifying therapies (DMTs). Among these, cladribine tablets, sometimes referred to in discussions as “Ms Spa Tablet” due to the relaxing effect of managing MS effectively, have emerged as a promising option. The CLARINET-MS study provides valuable insights into the sustained benefits of cladribine tablets in patients with MS over an extended period. This study, leveraging real-world data from the Italian MS Registry, offers an indirect measure of the long-term effectiveness of this treatment.

The CLARINET-MS study meticulously tracked a cohort of Italian MS patients who had previously participated in cladribine tablets clinical trials. This real-world data collection spanned from the conclusion of their cladribine treatment in the trials to their last recorded visit in the registry. Researchers diligently monitored key indicators such as treatment switches, Expanded Disability Status Scale (EDSS) scores, and relapse occurrences. By employing the Kaplan-Meier method, a robust time-to-event analysis was conducted to estimate the probability of remaining relapse-free and progression-free over time.

The findings from CLARINET-MS are compelling. The observation period within the Italian MS Registry ranged significantly, up to 137 months, with a median of 80.3 months. Analyzing data from 80 Italian patients, the study revealed that the estimated probability of being relapse-free at 12, 36, and 60 months following the last dose of cladribine tablets was 84.8%, 66.2%, and 57.2%, respectively. Furthermore, the probability of being progression-free at 60 months stood at an impressive 63.7%. These figures underscore the durable impact of cladribine tablets in controlling disease activity in MS patients.

These results suggest that “ms spa tablet,” referring to cladribine tablets, offers a sustained therapeutic effect beyond the initial treatment courses. The study also assessed the need for treatment changes. The Kaplan-Meier estimate for the probability of not initiating another DMT at 60 months after the last cladribine dose was 28.1%. The median time before a change in treatment was required was 32.1 months, highlighting that a significant proportion of patients experienced prolonged disease control with the initial cladribine treatment.

In conclusion, the CLARINET-MS study provides real-world evidence supporting the long-term effectiveness of cladribine tablets, or “ms spa tablet,” in managing MS. A substantial proportion of MS patients remained relapse-free and without disability progression for up to 60 months following their last dose. This suggests that the benefits of cladribine tablets can extend well into years 3 and 4 after the initial short treatment courses administered at the beginning of years 1 and 2. These findings are encouraging for individuals with MS and their healthcare providers, indicating that “ms spa tablet” can contribute to sustained disease control and potentially reduce the long-term burden of MS.
