Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study is a prospective, two-arm, open label trial of escalating doses of Cannabidiol (CBD) and Delta-9-Tetrahydrocannabinol (THC). The choice of the study drug will be at the discretion of the patient, doctor and dependent on supply. Each patient will follow a dose titration schedule for 14 days and a follow on stable dose for a further 14 days.
Concentration of medication:
Arm 1: CBD (Cannabidiol 100mg/ml) oral oily liquid
Arm 2: THC (Delta-9-Tetrahydrocannabinol 10mg/ml) oral oily liquid

Dosing schedule
Dose titration (days 0 – 14) will be confirmed by the treating doctor with doses starting at:
Arm 1
Days 0 & 1 – 1 dose/day = total daily dose 50mg (0.5ml)
Day 2 & 3 – 1 dose/day = total daily dose 100mg (1ml)
Day 4 & 5 – 2 dose/day = total daily dose 200mg (2ml)
Day 6 & 7 – 3 doses/day = total daily dose 300mg (3ml)
Day 8 & 9 – 3 doses/day = total daily dose 400mg (4ml)
Day 10 & 11 – 3 doses/day = total daily dose 500mg (5ml)
Day 12 & 13 – 3 doses/day = total daily dose 600mg (6ml)
Day 14 – 28 – Continue on final dose reached

Arm 2
Days 0 & 1 – 1 dose/day = total daily dose 2.5mg (0.25ml)
Day 2 & 3 – 1 dose/day = total daily dose 5mg (0.5ml)
Day 4 & 5 – 2 dose/day = total daily dose 10mg (1ml)
Day 6 & 7 – 3 doses/day = total daily dose 15mg (1.5ml)
Day 8 & 9 – 3 doses/day = total daily dose 20mg (2ml)
Day 10 & 11 – 3 doses/day = total daily dose 25mg (2.5ml)
Day 12 & 13 – 3 doses/day = total daily dose 30mg (3ml)
Day 14 – 28 – Continue on final dose reached

Each patient will be advised to increase their dose according to the dosing schedule until they are satisfied with their symptom improvement and there are no unacceptable side effects (according to CTCAE graded >4). The patient then will be given the option of remaining on the cannabinoid preparation for continuing assessment of efficacy and adverse events for a total of 28days.
Patients will have the choice of lowering their dose according to symptom improvement. Dose titration downwards will be in consultation with the doctor.

Statistical methods / analysis
Analysis will compose of assessing composite scores, rather than individual scores we have elected to use an improvement of >6 in the TSDS as the primary outcome measure. Descriptive analyses and frequency distributions will be generated from participants’ demographic and clinical characteristics, with all variables explored using graphical methods and summary statistics. Similarly, analysis of primary and secondary outcome will be descriptive only.
The aim is to recruit 5 participants in each arm (at day 14 – time of primary outcome) across a 12 month recruitment period in order to obtain sufficient pilot data to inform subsequent controlled trials. The sample size if currently restricted by the limited availability of approved products.
