Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Hypera®, (iX Biopharma, Australia), an sublingual wafer containing winterized THC Oil and less than 2% of other minor cannabinoids. Dose titration will occur day 1 – 7; they will receive sublingual Hypera® 5 mg before dinner on days one and two, titrated up to 5 mg three times a day, 1-2 hours before meals. There will be allowance for dose reduction if intolerable adverse effects to the prior dose level, which will then be carried to maintenance phase. The maintenance phase will be from day 8-14 Hypera® 5 mg tds before meals (or lower dose if required). The primary outcome will be measured on day 14. Participants without toxicity will then enter the two-week extension phase (day 15-28), with weekly assessments for efficacy and toxicity. At the end of the study participants will not continue on the study medication and will have a weaning phase over 4 days. There is a weekly, follow-up period of 28 days.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The active study medication and placebo will be manufactured to appear identical and packaged in pre-labelled blister by IX Biopharma, Australia (refer to section 5.1 for study intervention presentation). The licensed community pharmacy will dispense the study medication on a per participant basis. Upon receipt of a prescription, the delegated pharmacist at the third party pharmacy will dispense the appropriate stock of study medication Hypera 5 mg or placebo according to the treatment allocation derived from the randomisation schedule to provide participants with an initial two-week supply. Each randomisation kit will be blinded by the pharmacist prior to dispensing according to the method described in the pharmacy manual and affixed with a secondary dispensing label detailing the participant ID and the pre-determined allocation code.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The REDCap randomisation tool will be used to facilitate randomisation. Random allocation tables will be created and uploaded into the REDCap project. Treatment for each participant will be allocated according to a block randomisation schedule in a 1:1 ratio. Block randomisation will ensure even allocation to each code. There will be no stratification at the randomisation level for this study.

Efficacy
Statistical methods / analysis
Intention-to-treat analysis will be used for all statistical comparisons. For each treatment group and overall, the demographic data will be summarised as mean, standard deviation, minimum, median, and maximum for continuous variables, and as frequencies and percentages for categorical variables. Questionnaires that provide continuous responses will be summarised as described above with the addition of the 95% CI for the mean if appropriate. Questionnaires that provide categorical responses will be summarised as frequencies and percentages with the addition of 95% CI for the mean if appropriate.
