E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Transverse myelitis (TM) (acute, first onset cases), including first presentation of neuromyelitis optica (NMO) |
|
E.1.1.1 | Medical condition in easily understood language |
TM is a rare disease that affects the coating (myelin) of nerve cells in the spinal cord, causing inflammation which damages the cells: in NMO vision is also effected. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this randomized controlled trial is to evaluate if additional, and early, treatment with IVIg is of extra benefit in TM when compared to the current standard therapy of intravenous steroids. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to provide benefits whereby:
1. The clinical and para-clinical data collected from patients will provide a robust resource and platform for other clinical studies, including identification of early predictors of poor outcome.
2. Bio banked samples from patients recruited to the study will be collected and used for carefully designed biological studies by a consortium of established basic science researchers in the field.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients will be eligible for inclusion on the trial if on presentation they:
• Are aged 1 year or over
• Have been diagnosed with:
EITHER acute first onset transverse myelitis
(The TM CONSORTIUM WORKING GROUP 2002 criteria for probable TM will be used. Hence, following clinical and radiological exclusion of a compressive myelopathy, patient will be diagnosed to have TM if they meet all the following criteria:
Sensory, motor, or autonomic dysfunction attributable to the spinal cord
Bilateral signs and/or symptoms (not necessarily symmetric)
Sensory level (except in young children <5 years where this is difficult to
evaluate)
Lack of MRI brain criteria consistent with MS (McDonald 2010 space criteria)
Progression to nadir between 4 h and 21 days)
OR Have been diagnosed with first presentation of neuromyelitis optica.
(Patients with definite modified NMO will meet the following criteria (Wingerchuck et al, 2006).
Absolute criteria, both:
1. Optic neuritis
2. Acute myelitis
Plus two out of three supportive criteria:
i. Brain MRI not meeting criteria for MS at disease onset
ii. Spinal cord MRI with contiguous T2-weighted signal abnormality extending over
three or more vertebral segments, indicating a relatively large lesion in the
spinal cord
iii. NMO-IgG seropositive status)
• Have an ASIA Impairment score of A, B or C
• Give assent/consent to participate in the trial
|
|
E.4 | Principal exclusion criteria |
Patients would be excluded if they show evidence of:
• Contraindication to IVIg as stated in the product SmPC, or receiving IVIG for
other reasons
• Previously known systemic autoimmune disease (eg systemic lupus erythematosus) or
any evidence of systemic inflammation during current presentation.
• Direct infectious aetiology (eg varicella zoster)
• Previous episode of CNS inflammatory demyelination
• Acute disseminated encephalomyelitis (ADEM)
• Other causes of myelopathy not thought to be due to myelitis (eg nutritional,
ischaemic, tumour etc.)
• Pregnancy
•Circumstances which would prevent follow-up for 12 months |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Primary outcome measure is defined as the binary responder, being an improvement of 2 points or greater on the ASIA scale (classified A-E) at 6 months post randomisation |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary outcome is measured at timepoint T2, 6 months post randomisation. |
|
E.5.2 | Secondary end point(s) |
SECONDARY
1. Change in ASIA motor and sensory scales (0-100) at 3, 6, and 12 months
2. Change in Kurtzke expanded disability status scale (EDSS) at 3, 6, and 12 months
3. Individuals >7 years: EQ-5D-Y for patients age 7-12 and EQ-5D > 12; short standardised instrument for measurement of health outcomes to be used in health economics assessment at 3, 6, and 12 months
4. Individuals ≥ 12 years: International SCI Quality of Life Basic Data Set at 6 and 12 months
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Secondary end points 1, 2 and 3 are evaluated at timepoints T1 (3 months post randomisation)6 , T2 (6 months post randomisation) and T3 (12 months post randomisation).
Secondary end point 4 is evaluated at timepoints T2 ad T3.
Tertiary end points are measured ate timepoints T2 and T3. |
