Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The investigational product (IMP) is oral medicinal cannabis oil (10mg/ml CBD:10mg/ml THC) supplied by Little Green Pharma (LGP). Excipient: Medium chain triglycerides oil (MCT), derived from sustainably sourced palm oil. The IMP can vary in colour from a transparent coloured oil to a to pale golden yellow coloured oil. The IMP is supplied in a 50mL pharmaceutical-grade amber glass bottle with a tamper-evident seal child-resistant cap. A plastic graduated 1 ml oral syringe is provided.

Due to intra-variability of participants' metabolism and response to cannabis, an initial slow increase of dose will occur for the first 4 weeks (titration) to establish the tolerated dose for that participant. After the titration period, the participants will take that dose for another 12 weeks to examine its effects on pain and other symptoms associated with fibromyalgia such as sleep, mood, and quality of life. The study duration is 16 weeks in total, plus a 4-week follow-up phone call after ceasing the medication.

During titration, participants will begin by taking 0.25ml orally 30-60 minutes before bedtime. Every two days, patients may increase the dosage by 0.25ml unless they are experiencing any undesirable side effects. If they notice any of these, they should decrease the dose by 0.25ml on the following day. The dosage should be altered only with incremental increases/decreases of 0.25 ml each time and maintained at whichever dosage proves successful once identified for the remainder of the trial. The maximum daily dosage should not exceed 3.5ml taken before bed.

Upon completion of the trial, all participants will discontinue use without tapering off and be offered one free 50ml bottle of the product utilised in the trial if desired, offering 25 days’ worth of treatment at an average of 2ml nightly.

Participants' adherence to the intervention will be monitored by measuring the remaining unused intervention oil at each follow-up meeting to calculate the number of doses missed. These will also be checked against the participant's diaries.

Comparator / control treatment
The control treatment will be the placebo group. The placebo will be composed of medium chain triglyceride (MCT) oil and small amounts of walnut and avocado oil to resemble the IMP in colour, texture and smell. Both the IMP and placebo will appear as a thick liquid in a dark glass 50 ml bottle with appropriate clinical trial labels on it.

A titration strategy similar to the one employed by the intervention group will be implemented for the placebo group. Participants will begin with an oral dosage of 0.25ml 30-60 minutes before bedtime and increase the dosage by 0.25ml every two days, not exceeding a daily maximum of 3.5 ml.

Participant adherence to the control treatment will be monitored by measuring the remaining unused intervention oil at each follow-up meeting to calculate the number of doses missed. These will also be checked against the participant's diaries.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The active and placebo bottles will appear identical from the outside and have the same weight.
A delegated unblinded Griffith University Clinical Trial Unit (CTU) staff member will receive the randomisation sequence information and receive access to the trial medications. Each drug will be in a box with either ‘1’ or ‘2’ on it. Based on the list, the unblinded CTU staff members will label each bottle with the trial number from the randomisation list supplied. The box with the ‘1’ or ‘2’ numbers will be disposed of to assist with concealment. The final bottles will not contain any group allocation information, but only be assigned based on participant ID of enrolled participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation sequence will be a computer-generated random number based on block randomisation with varying block length ranging from 2 to 6. No strata will be applied. The randomisation sequence will be generated via the online platform randomizer.org.

Statistical methods / analysis
All data will be analysed via SPSS 27.0. Analyses will be conducted on an intention-to-treat basis. An additional per-protocol analysis will be conducted. This means all participants randomised into the study that received the protocol required study product (administered at least 90% each week) exposure for at least one month will be analysed to examine the effect of compliance on the outcomes.
Basic sociodemographic and clinical data (i.e., comorbidity, medication, cannabis, or other substance use) will be collected at baseline to describe the sample and identify any confounding variables that need to be considered in the statistical analyses.
SAMPLE SIZE:
A sample size of 30 participants is considered adequate for a feasibility trial based on Browne’s flat rule of thumb for a two-armed pilot trials (Browne 1995). This feasibility trial will aim to recruit 36 participants in total (allowing 20% attrition, 18 participants per study arm).
PRIMARY OUTCOMES:
Descriptive statistics will summarise the primary outcome data as either means (absolute, relative or percentage change) with standard deviations or medians with interquartile range as appropriate for continuous data. Absolute and relative frequencies will be used for categorical variables.
SECONDARY OUTCOMES:
Clinical outcomes:
Scores of the following instruments will be compared between groups after 12 weeks at full titration, using univariate analysis (ANCOVA) or equivalent non-parametric test, depending on the distribution of data, and the effects reported as group differences with 95% confidence intervals:
1. FIQ (disability)
2. SF-36 (quality of life)
3. ADPS (pain)
4. HADS (depression)
5. PSQI (sleep)
6. MFI-20 (fatigue)
NO SIGNIFICANCE TEST will be conducted, but preliminary effect sizes will be determined to inform future studies. The responder rates will be compared using Chi2 tests. The proportion of patients reaching the predefined minimum clinically important difference (MCID) values for FIQ and ADPS scores will be identified using a Chi2 test.
Laboratory outcomes:
The following laboratory outcomes will be compared using ANCOVA and t-tests to determine if significance exists between the two groups:
1. Plasma cytokine concentrations
2. Plasma endocannabinoid concentrations.
Other statistical testing means will be assessed once the data is collected.

Summary
Brief summary
This project aims to assess the feasibility, safety, and potential efficacy of oral cannabis oil in relieving pain and other symptoms in people with fibromyalgia syndrome (FMS). Thirty-six patients (n=36, allowing 20% attrition) diagnosed with FMS will be recruited to take part in a 16-week double-blind, randomised, placebo-controlled trial. Eighteen patients will be given a product containing cannabis oil; the other 18 participants will receive a placebo oil similar in look, taste, and smell. Due to intra-variability of participants metabolism and response to cannabis, an initial slow increase of dose will occur for the first 4 weeks to establish the tolerated dose for that participant. They will then take that dose for another 12 weeks to examine its effects on pain and other symptoms associated with FMS such as sleep, mood, and quality of life.
