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 study aims to address the following questions:
1) Does dronabinol have any value in slowing progressive MS over a three-year period? This tests the hypothesis that cannabinoids have a neuroprotective action and builds on the Cannabinoids in Multiple Sclerosis (CAMS) study.
2) Is dronabinol safe over the long-term?
3) Can research methodology be improved by using newer patient-orientated methods? This trial will act as a bridging study between older outcome measures and newer, patient-orientated measures that are more sensitive and considerably easier to administer. During the course of the study we will concentrate on evaluating the meaning of a clinically significant effect.

E.2.2 | Secondary objectives of the trial |
The secondary objectives are:
1) To gather information on both the public and personnel costs associated with MS and to assess the cost-effectiveness of treatment with dronabinol in progressive MS.
2) To create a resource of DNA and serum samples to permit future analysis for disease biomarkers.

E.3 | Principal inclusion criteria |
Inclusion criteria:
-Primary or secondary progressive MS, assessed according to McDonald criteria. -Aged 18 - 65 years. -Disease progression (increase in physical disability, not due to major relapses) in preceding year in the opinion of the treating physician. -EDSS of 4.0 to 6.5 inclusive. -Willing and able to comply with study visits according to protocol for the full study period. -Willing to abstain from cannabis use (excluding study medication) for three years.

E.4 | Principal exclusion criteria |
Exclusion criterion:
-Any immunosuppressive or immunomodulatory therapy received in the previous 12 months. -Any experimental therapies with potential disease modifying actions (including stem cells, goat serum and low dose naltrexone) in the previous 12 months. -Corticosteroids received in the previous three months. -Significant* MS relapse, likely to have had an effect on EDSS, occurring in the previous six months. -Predominantly relapsing-remitting disease over the previous 12 months. -Other serious illness or medical condition likely to interfere with study assessment, including ischaemic heart disease or evidence of chronic infection from any source, including pressure sores. -Previous history of psychotic illness. -Sesame seed allergy. -Severe cognitive impairment such that patient is unable to provide informed consent. -Women who are pregnant, breast-feeding or planning a pregnancy within the next three years. -Cannabinoids (including Nabilone) taken in previous four weeks (negative urinalysis required). -Participation in another interventional study within the last three months. -Any other factor that might interfere with long-term study compliance in the opinion of the local research team.

E.5 End points |
E.5.1 | Primary end point(s) |
Physician-based EDSS: time to EDSS progression of at least one point from a baseline EDSS of 4.0, 4.5 or 5.0 or at least 0.5 points from a baseline EDSS ≥5.5. Once identified, deterioration must be confirmed at the next scheduled six monthly visit.
Patient-based MSIS-29 physical impact scale: overall mean change from baseline to end of study.
In order to progress outcome measurement and trial design methodology in MS treatments, the study includes two primary outcome measures. Since it remains the most widely used scale, the clinician-orientated EDSS, based on the neurological examination, will be used. In addition, the well-validated MSIS-29, a more sensitive measure which incorporates the patient perspective, will be included. The use of two measures recognises that patients’ perceptions may differ from those of clinicians, and enables comparison of those differences. It will also provide important information on the comparative behaviour of the measures in clinical trials, and act as a platform for further studies in MS. Rating scales used in this study have been chosen to measure both clinician-based and patient based outcomes. In addition, the scale selection takes into account the fact that no one scale is sufficient for the study.
