E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Degenerative Cervical Myelopathy |
|
E.1.1.1 | Medical condition in easily understood language |
‘Wear and tear’ arthritis (degenerative) affects the part of the spine in the neck (cervical), causing structural changes that compress and damage the spinal cord (myelopathy) |

E.1.1.2 | Therapeutic area | Diseases [C] - Nervous System Diseases [C10] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of this trial is to estimate the difference in the modified Japanese Orthopaedic Association (mJOA) score and the Visual Analogue Scale (VAS) neck pain at 6 months after surgery between Degenerative Cervical Myelopathy (DCM) patients randomised to Ibudilast and those randomised to placebo. The mJOA is a fully validated outcome assessment for function in DCM. The VAS is the most popular tool for the measurement of pain in DCM. The hypothesis is that Ibudilast improves neurological recovery following surgical decompression of DCM. |
|
E.2.2 | Secondary objectives of the trial |
1) To compare the clinical efficacy of Ibudilast treatment at 3, 6 and 12 months after surgery, using a representative range of DCM outcome assessments
The exploratory objectives include: 1) To undertake a health economic evaluation of Ibudilast therapy 2) To assess the bioavailability of Ibudilast in the CSF and blood. 3) To assess the informal care burden of DCM 4) To assess the potential of novel quantitative clinical assessments (Gait Laboratory)

|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
1. Carer Quality of Life (QoL) (Optional): Objective: to assess the informal care burden of DCM Carers of trial subjects, as many as would like to be involved, will be asked to complete the CarerQOL self-assessment at baseline, preoperatively and 3, 6 and 12 months post-operatively.
The questionnaire will also include their relation to the study participant. The questionnaire takes approximately 10 minutes to complete.
2. Gait Lab (sub-study for Addenbrooke’s only): Objective: to assess the potential of gait laboratory as a novel quantitative clinical assessments Alongside their clinician-administered assessments, patients at Addenbrooke’s only will be invited to complete a formal, quantitative gait assessment. This involves walking across a pressure sensitive floor mat that will collect information about the steps, pressure, time elapsed, stride length and width. The assessment takes approximately 10 minutes and will be performed in the pre-operative visit and the 3 and 6 months post-operative visits. All Addenbrooke's trial participants will be invited to participate in this sub-study. |

• Previous surgery for DCM • DCM symptoms due to cervical trauma (at the discretion of the investigator) • Hypersensitivity to Ibudilast or any of the formulation components • Evidence of acute hepatitis, clinically significant chronic hepatitis, or evidence of clinically significant impaired hepatic function through clinical and laboratory evaluation including ALP> 1.5x ULN; ALT or AST > 2x ULN; GGT > 3x ULN • Evidence of thrombocytopenia at screening through laboratory evaluation including platelet count <5000 • Active malignancy defined as history of invasive malignancy, except if the patient has received treatment and displayed no clinical signs and symptoms for at least five years • Recent history (less than 3 years) of chemical substance dependency or significant psychosocial disturbance that may impact the outcome or trial participation • Female patients with child bearing potential who are unwilling or unable to use reliable methods of contraception • Female patients who are pregnant, lactating or planning pregnancy during the course of the trial. • Inability to comply with trial procedures or follow-up schedule including IMP regime • Unable to take gelatin based product • Participation in another CTIMP or device within the past 30 days from the time of recruitment • Functional disability from a concomitant neurological disease that would mask the symptoms of DCM (at the discretion of the investigator). Including but not limited to stroke with residual disability, cerebellar ataxia, Parkinson’s disease, symptomatic lumbar stenosis and multiple sclerosis. • Resting pulse < 50 bpm, SA or AV block, uncontrolled hypertension, or QTcF > 450 ms • History of stomach or intestinal surgery or any other condition that could interfere with or is judged by the investigator to interfere with absorption, distribution, metabolism, or excretion of IMP • Unable to converse, read or write English |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measures are the change in the modified Japanese Orthopaedic Association Score (mJOA) and the change in Visual Analogue Scale (VAS) neck pain between screening and 6 months post-operatively. The mJOA is an 18-point clinician administered scale (0 worst to 18 best), which evaluates motor dysfunction in upper and lower extremities, loss of sensation, and sphincter dysfunction. The VAS Neck pain is a 10cm horizontal line, on which a patient indicates their level of neck pain from 0 (no pain) to 10 (worst pain). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary outcome will be evaluated as the difference in these parameters between baseline (screening visit) and 6-months post-operatively (±21 days). These two parameters are also evaluated for exploratory purposes in the pre-operative, 3 months and 12 months follow-up visits. VAS neck pain is also evaluated for exploratory purposes at post-operative visit. |
|
E.5.2 | Secondary end point(s) |
1. Physical Summary Score (PSC) of the Short Form 36 (SF-36) questionnaire: a well-recognised measure of patient physical health 2. Mental Summary Score (MSC) of the Short Form 36 (SF-36) questionnaire: a well-recognised measure of patient mental health |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
SF36 is evaluated at screening, pre-operative and then 3, 6 and 12 months post-operatively |
