Demyelinating Diseases of the Central Nervous System Registry for Patients with Traditional Chinese Medicine (DATE-TCM) is an observational study aiming to better define the multidimensional (epidemiologic, demographic and clinical) characteristics of Demyelinating Diseases of the Central Nervous System (DDC) patients receiving Traditional Chinese medicine (TCM) treatment, the type and long-term safety and effectiveness of TCM in DDC populations, as well as the interaction of TCM treatment and disease-modifying therapy in the management of DDC.
Demyelinating Diseases of the Central Nervous System (DDC) is a collective term for a group of immune-mediated disorders including multiple sclerosis, Neuromyelitis optica spectrum disorder, and myelin oligodendrocyte glycoprotein associated disorder, characterized by myelin loss and axonal damage in the central nervous system. Traditional Chinese medicine (TCM), a main form of complementary and alternative medicine provides a potential possibility to DDC management and has been applied to a considerable number of patients with this disorder in China as well as in other regions or countries worldwide. Demyelinating Diseases of the Central Nervous System Registry for Patients with Traditional Chinese Medicine (DATE-TCM) provides a prospective and voluntary registry aiming to include 2000 eligible adult DDC patients with TCM intervenes from around 30 participating centers by using a web-based system. Baseline data will be recorded and subsequently regular follow-up visits will be implemented every 3-6 months for a total of 5 years. Main objective of DATE-TCM is to create an organized multicenter structure to collect reliable data for better define the multidimensional (epidemiologic, demographic and clinical) characteristics of DDC patients receiving TCM treatment, the type and long-term safety and effectiveness of TCM in DDC populations, as well as the interaction of TCM treatment and disease-modifying therapy in the management of DDC.

Annualized Aggregate Relapse Rate (ARR)
ARR is defined as the number of confirmed relapses in a year. A relapse is defined as the appearance of a new or worsening of a previously stable or improving pre-existing neurological abnormality, separated by at least 30 days from onset of a preceding relapse. The abnormality must be present for at least 24 hours and occur in the absence of fever or infection. The ARR was the mean of the annualized ARRs for all patients, calculated as the total number of confirmed relapses divided by the total number of days on study multiplied by 365.25.
Time frame: Baseline up to 5 years
Total Number of Adverse Events During Evaluation
Adverse Events (AE) are any unfavorable and unintended sign, symptom, syndrome, or illness observed by the investigator or reported by the participant during the study.
Time frame: Baseline up to 5 years
Percentage of Participants With Adverse Events
Adverse Events (AE) are any unfavorable and unintended sign, symptom, syndrome, or illness observed by the investigator or reported by the participant during the study.
Time frame: Baseline up to 5 years
Time to 3-month Sustained Disability Progression
3-month sustained disability progression (DP) was defined as an increase from baseline of at least 1-point in EDSS score (at least 0.5-point for participants with baseline EDSS score \>5.5) that persisted for at least 3 months. EDSS scale ranges from 0 (Normal neurological exam, no disability) to 10 (Death) in 0.5 unit increments that represent higher levels of disability. Scoring is based on an examination by a neurologist. Kaplan-Meier method consists in computing probabilities of non-occurrence of event at any observed time of event and multiplying successive probabilities for time ≤t by any earlier computed probabilities to estimate the probability of being event-free for the amount of time.
Time frame: 5 years
Time to 6-month Sustained Disability Progression
6-month sustained disability progression (DP) was defined as an increase from baseline of at least 1-point in EDSS score (at least 0.5-point for participants with baseline EDSS score \>5.5) that persisted for at least 6 months. EDSS scale ranges from 0 (Normal neurological exam, no disability) to 10 (Death) in 0.5 unit increments that represent higher levels of disability. Scoring is based on an examination by a neurologist. Kaplan-Meier method consists in computing probabilities of non-occurrence of event at any observed time of event and multiplying successive probabilities for time ≤t by any earlier computed probabilities to estimate the probability of being event-free for the amount of time.
Time frame: 5 years
Number of New or Newly Enlarging T2 hyperintense lesions as Measured by Magnetic Resonance Imaging (MRI)
The number of new or newly enlarging T2 hyperintense lesions that developed in each subject compared to baseline assessed on magnetic resonance imaging (MRI) scans. The estimates of mean T2 hyperintense lesion count were calculated from a negative binomial regression model adjusted for region and baseline T2 hyperintense lesion volume.
Time frame: From baseline to 12 months, 24 months, 36 months, 48 months, 60 months
Number of Gadolinium-enhancing T1-weighted Lesions as Measured by Magnetic Resonance Imaging (MRI)
The number of Gd-enhancing lesions was assessed by using MRI scans following administration of gadolinium, a contrast agent.
Time frame: From baseline to 12 months, 24 months, 36 months, 48 months, 60 months
Percent Change in Brain Volume Measured by Magnetic Resonance Imaging (MRI)
Calculations of brain volume change were performed using the structural image evaluation of normalized atrophy (SIENA), software included in the Functional Magnetic Resonance Imaging of the Brain (FMRIB) software library.
Time frame: From baseline to 12 months, 24 months, 36 months, 48 months, 60 months
Change in Multiple Sclerosis Functional Composite (MSFC) score
The Multiple Sclerosis Functional Composite (MSFC) is a multidimensional clinical outcome measure that includes quantitative tests of leg function/ambulation (Timed 25-Foot Walk), arm function (9-Hole Peg Test), and cognitive function (Paced Auditory Serial Addition Test).
Time frame: Every 6 months up to 5 years
Change in Symbol Digit Modalities Test (SDMT) score
The SDMT measures the time to pair abstract symbols with specific numbers. The test requires elements of attention, visuoperceptual processing, working memory, and psychomotor speed. The score is the number of correctly coded items from 0-110 in 90 seconds. The total score provides a measure of the speed and accuracy of symbol-digit substitution.
Time frame: Every 6 months up to 5 years
Chance in fatigue severity scale (FSS) score
FSS is a short questionnaire that requires patient to rate level of fatigue.
Time frame: Every 6 months up to 5 years
Change in EuroQol- 5 Dimension (EQ-5D) score
The EQ-5D descriptive system is a preference-based HRQL measure with one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. A mixed effect model for repeated measures was used for this analysis. An unstructured covariance was used to model within-participant error.
Time frame: Every 6 months up to 5 years
Change from Multiple Sclerosis impact scale (MSIS) score
The MSIS-29 is a disease specific patient-reported outcome measure that has been developed and validated to examine the physical and psychological impact of MS from a patient's perspective; it measures 20 physical items and 9 psychological items. A mixed effect model for repeated measures was used for this analysis. An unstructured covariance was used to model within-participant error.
Time frame: Every 6 months up to 5 years
