Clinical Trial Summary

Central nervous system (CNS) idiopathic inflammatory demyelinating diseases (IDD) are mainly diseases caused by autoimmune factors that result in CNS demyelination damage and loss. It tends to accumulate in the brain, spinal cord and optic nerves. Multiple sclerosis (MS), clinically isolated syndrome (CIS), neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and acute disseminated encephalomyelitis (ADEM) are all common IDDs of the CNS. Besides, primary angiitis of the central nervous system (PACNS), autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A), etc. may also be included because they are important differential diagnoses. This study will establish a large prospective cohort study database of Chinese IDD, which will record detailed electronic information on IDD patients, including demographic and socioeconomic data, medical history, clinical information, medication, and relevant examination results. The long-term observational study will be used to understand the natural history of disease, disability progression rates, imaging and biological indicators, long-term treatment approaches and prognosis of Chinese patients with IDD, to find predictive markers for IDD progression and prognosis, and to identify factors that influence the treatment and prognosis of patients with IDD.

Description:

Large prospective cohort studies allow long-term observation and analysis of the clinical status and disease activity of IDD patient population, and are the best way to understand IDD's natural course, clinical outcome, and drug efficacy in specific populations. Globally, several large prospective follow-up cohort studies have been conducted, providing important information on the disease characteristics of IDD patients. However, there is no large nationwide registry study of CNS IDD in China, and therefore there is a relative lack of data on the natural course of disease and drug efficacy in the Chinese IDD patient population, as well as a lack of standardized follow-up management of Chinese IDD patients. This study will establish a large prospective cohort study database of Chinese IDD, which will record detailed electronic information on IDD patients. We aim to establish a national (multicenter) disease registry for central nervous system idiopathic inflammatory demyelinating diseases in China, and to establish a unified standardized follow-up management process and treatment guidelines for patients with IDD in China; To provide real world data on the disease status of Chinese IDD patients; To understand the disease progression characteristics of IDD in China; To search for biological and imaging markers that predict the relapse, progression, and prognosis of IDD; to investigate the efficacy, safety, compliance and switch of different disease-modifying drugs (DMDs) in the long-term treatment of Chinese patients with IDD. The study is a prospective observational (non-interventional) national multicenter cohort study to collect clinical data from IDD patients who have signed informed consent, to routinely and regularly follow up IDD patients on multiple clinical indicators, and to assess clinical outcomes. All information is to be completed prospectively from the time point the patient visited the hospital (except for Basic patient information and information about previous disease that are required at enrollment follow-up).Once the project started, the study sites are not allowed to discontinue the study on their own until the end of study is announced. In addition, to ensure the continuity of the data, each site needs to appoint designated clinical data collectors to collect data from qualified inpatient clinical cases consecutively, so as to ensure the consecutive registration of each inpatient case who meets the inclusion and exclusion criteria. As the purpose of this study is to establish a national multicenter disease registry to provide disease-related information on patients with IDD in China, and the primary and secondary endpoints of the study being descriptive endpoints, therefore no formal calculation of sample size is needed. 10000 IDD patients are planned to be recruited.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Annual relapse rate (ARR) between baseline and follow-up in patients with IDD	a new neurological worsening lasting for at least 24 hours and occurring more than 30 days after the previous attack.	baseline up to 5 years
Primary	Change in EDSS scores of patients with IDD between baseline and follow-up over time	The Expanded Disability Status Scale (EDSS) is a rating system that is frequently used for classifying and standardizing the severity and progression. EDSS ranges from 0 to 10. The higher the score, the worse the clinical symptoms.	baseline, Month 6, Month12, Month18, Month24, Month30, Month36, Month42, Month48, Month54, Month60
Secondary	The brain structural change over time between the baseline MRI and the follow-up MRIs	To describe changes of lesions, grey matter and white matter in patients with neuroinflammatory and demyelination disease measured by Brain Magnetic Resonance Imaging (MRI). The MRI sequence includes T2W_TRA?DWI?3DT1W_TFE_SAG?fMRI_EPI_TRA?mb2DKI_iso48_b1k2k_TRA?3DFLAIR_TSE_SAG?3DpCASL_GRASE_TRA?3DDIR_SAG?3DT2W_TSE?SWI_QSM_TRA. The secondary endpoint is the change over time between the baseline MRI and the follow-up MRIs, of the lesions and brain volumes.	baseline, year1, year2, year3, year4, year5.
Secondary	The spinal cord change over time between the baseline MRI and the follow-up MRIs.	To describe changes of lesions and integrity of fiber bundle in spinal cord in neuroinflammatory and demyelination disease patients measured by MRI. The primary endpoint is the change over time between the baseline MRI and the follow-up MRIs, of structural change in spinal cord.	baseline, year1, year2, year3, year4, year5.
Secondary	Change of the central vein sign at 7T MRI.	The central vein sign has been proposed as a specific imaging biomarker for distinguishing between multiple sclerosis (MS) and not MS.	baseline, year1, year2, year3, year4, year5.
Secondary	Change of rim of iron at 7T MRI.	multiple sclerosis white matter lesions surrounded by a rim of iron containing microglia, termed iron rim lesions, signify patients with more severe disease course and a propensity to develop progressive multiple sclerosis.	baseline, year1, year2, year3, year4, year5.

Secondary	Changes in cognitive function of patients with IDD at baseline and over time during follow-up	Scale assessment mainly rely on SDMT(Symbol Digit Modalities Test), MoCA( Montreal Cognitive Assessment), MMSE(Mini-mental State Examination) and so on. The Symbol Digit Modalities Test (SDMT) is widely used because it is easy to administer, reliable and also evaluates information processing speed. The Montreal Cognitive Assessment (MoCA) is a brief, 30-question test that helps healthcare professionals detect cognitive impairments very early on, allowing for faster diagnosis and patient care. The Mini-Mental State Exam (MMSE) is a widely used test of cognitive function among the elderly; it includes tests of orientation, attention, memory, language and visual-spatial skills.	baseline, year1, year2, year3, year4, year5.
