Using Data

Background: The CLARINET-MS study assessed the long-term effectiveness of cladribine tablets by following patients with multiple sclerosis (MS) in Italy, using data from the Italian MS Registry. Methods: Real-world data (RWD) from Italian MS patients who participated in cladribine tablets randomised clinical trials (RCTs; CLARITY, CLARITY Extension, ONWARD or ORACLE-MS) across 17 MS centres were obtained from the Italian MS Registry. RWD were collected during a set observation period, spanning from the last dose of cladribine tablets during the RCT (defined as baseline) to the last visit date in the registry, treatment switch to other disease-modifying drugs, date of last Expanded Disability Status Scale recording or date of the last relapse (whichever occurred last). Time-to-event analysis was completed using the Kaplan–Meier (KM) method. Median duration and associated 95% confidence intervals (CI) were estimated from the model. Results: Time span under observation in the Italian MS Registry was 1–137 (median 80.3) months. In the total Italian patient population ( n = 80), the KM estimates for the probability of being relapse-free at 12, 36 and 60 months after the last dose of cladribine tablets were 84.8%, 66.2% and 57.2%, respectively. The corresponding probability of being progression-free at 60 months after the last dose was 63.7%. The KM estimate for the probability of not initiating another disease-modifying treatment at 60 months after the last dose of cladribine tablets was 28.1%, and the median time-to-treatment change was 32.1 (95% CI 15.5–39.5) months. Conclusion: CLARINET-MS provides an indirect measure of the long-term effectiveness of cladribine tablets. Over half of MS patients analysed did not relapse or experience disability progression during 60 months of follow-up from the last dose, suggesting that cladribine tablets remain effective in years 3 and 4 after short courses at the beginning of years 1 and 2.

Abstract While the safety and efficacy of Disease Modifying Therapy (DMT) in multiple sclerosis (MS) are assessed in clinical trials, these are of relatively short duration and always confined to highly selected patient groups. The evaluation of real-world data such as patient registries, is vital as it offers long-term data collection and is patient rather than product-focused during the lifetime of MS, and allows to document a patient's treatment history throughout the disease course. Patient registries can play an important role in monitoring the safety of drus. Regulators and the pharmaceutical industry have shown interest in complementing or even replacing phase 4 clinical studies with data from MS registries. The Italian MS Register (IMSR), in collaboration with the Big MS Data initiative, that also includes the national MS registries of Denmark, France, and Sweden and the international database network MSBase, came together with industry to conduct studies on post-authorization safety (PASS) and treatment effectiveness. The IMSR includes the clinical history of approximately 55,000 patients, or approximatively 45% of the estimated cases of MS in Italy. More than 10,000 patients have a follow-up duration of over 10 years. A Core Protocol outlining principles of PASS projects was created in which aggregated results made available to sponsors and health authorities. The Core Protocol specifies variables, emphasizes improved capture of adverse events, in particular cancer, non-melanoma skin cancers and immunosuppression-related infections, all MedDRA-coded. EUROCAT codes for pregnancy outcomes are also documented. Regulators, the pharmaceutical industry and national-level registries have jointly identified a format of collaboration on PASS for DMT in MS to benefit patients and the larger society. In this way, we hope to contribute to a framework that will include emerging and existing registries with the common goal of contributing to the advancement of knowledge in MS. Key messages The real-world data can contribute to understanding of the impact of disease-modifying therapy on long term. A format of collaboration among clinical research, regulators and pharmaceutical industry could be a winning framework to improve the knowledge on safety and treatment effectiveness in MS.

Disease Modifying

Multiple sclerosis (MS) is more common in women than men and is most commonly diagnosed in early adulthood; thus, many patients will not have completed their families at the time of diagnosis. There is increasing awareness of the importance of early treatment in preventing long-term disability in MS. Delaying treatment until women with MS have completed their families can lead to the development of irreversible disability in at least some cases. It is therefore important to discuss family planning and pregnancy proactively. However, to date there is limited evidence to inform such discussions. We set out to develop consensus guidelines for the treatment of MS in pregnancy to encourage and facilitate discussions in this important area. The guidelines draw on available evidence from drug-specific pregnancy registers and published literature and have been scored by a panel of experts from a variety of disciplines using modified Delphi criteria. They cover prepregnancy counselling, management during pregnancy, delivery and anaesthetic options, postpartum advice and specific advice regarding currently licensed disease-modifying drugs. As the complexity and range of available disease-modifying drugs increase, further data gathering via a UK-wide MS pregnancy register is recommended.
