- Brief Summary
This was a multicenter, non-interventional, retrospective study aiming to evaluate the real-world effectiveness and safety of siponimod treatment in Chinese patients with relapsing forms of multiple sclerosis (RMS). The data were collected retrospectively through medical records review and abstraction conducted at a single time point per patient by the investigator's site staff or a designate (at the discretion of the site, if allowed by local regulations). There was no prospective patient follow-up for this study. Obtaining informed consent was based on local regulations. Where permissible, waivers could be applied to the Institutional Review Board (IRB) or Independent Ethics Committee (IEC) as appropriate, based on the retrospective collection of non-personally identifiable data, if acceptable per local regulations.
The target patient population included adult patients diagnosed with RMS (including clinically isolated syndrome (CIS), relapsing-remitting multiple sclerosis (RRMS), or active secondary progressive multiple sclerosis (SPMS)), and who received at least 3-months of treatment with siponimod after the index date. The index date is the date of siponimod initiation, defined as the date of first prescription record of siponimod in the patient's medical records with RMS diagnosis. Effectiveness data (i.e., clinical relapses, magnetic resonance imaging (MRI) activity) were collected from the index date, through the end of the observation period. The observation period was from the index date to the date of initiation of medical records abstraction at site, or patient withdrawal of consent, loss of follow-up, or death, whichever occurred first. Among patients who permanently discontinued siponimod during the observation period, safety data were collected up to 30 days after the last dose of siponimod.

- Primary Outcome Measures
Name Time Method Annualized Relapse Rate (ARR) Up to approximately 32 months The ARR was calculated using the total number of relapses (as documented in the patient's medical records) after index date divided by the total person days of follow-up after index date multiplied by 365.25.
- Secondary Outcome Measures
Name Time Method Proportion of Patients with Selected Notable Abnormal Laboratory Data Up to approximately 32 months Selected notable abnormal laboratory data included complete blood count with differential lymphocyte count and liver function tests.
Proportion of Patients Relapse-free at 12 Months after Index Date 12 months Proportion of Patients Free of Magnetic Resonance Imaging (MRI) Activity at 12 Months after Index Date 12 months Proportion of Patients with Treatment-emergent Adverse Events (TEAEs), per Category Up to approximately 32 months Categories were TEAEs, treatment-related TEAEs, serious TEAEs, TEAEs leading to discontinuation of siponimod, TEAEs leading to death, and TEAEs of special interest (AESIs).
TEAEs were defined as any AEs that were not presented prior to medical treatment, or an already presented event that worsens either in intensity or frequency following the treatment, that developed after siponimod initiation.
