Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The trial will commence with a two-week baseline observation period, where measurements relating to symptom burden will be measured. Participants will then be randomised to one of two-arms to receive combinations of Tetrahydrocannabinol (THC) and Cannabidiol (CBD) oral cannabis oil. Doses will be titrated upwards over two weeks, to a dose where symptom relief with tolerable side effects is achieved (as measured by clinical assessment and the 32 item Memorial Symptom Assessment Scale (MSAS) Global Distress Index). This will be followed by a four week maintenance phase on a stable dose as determined by the 2-week titration period. Blood will be drawn for pharmacokinetic and biomarker analysis at week -1 (week prior to commencement of intervention), week 2 of dose titration, and week 6 of intervention (end of 4-week maintenance phase). Symptom burden will be measured at weekly clinic appointments through the trial using the Memorial Symptom Assessment Scale. Confirmed documented disease will be assessed at days 14 and 28, 42 and 56 (where applicable). Participants wishing to access medicinal cannabis beyond the clinical trial period will be able to do so via the Special Access Scheme B. Patients not wishing to continue use of medicinal cannabis will have the product slowly titrated down over a one week period at the end of the clinical trial. Participants will be contacted at day 86 (+ 4 weeks post last dose) for the purposes of safety follow up and recording of post-study medicinal cannabis use.

Arm 1: THC: CBD Equivalent Investigational Product, with a 1:1 ratio of 10 mg THC and 10 mg CBD per mL in an oral MCT oil vehicle (Little Green Pharma).
This Investigational Product will be upwardly titrated during a two-week Dose Titration Phase from 0.1mg/0.1mg/kg/day to a maximum of 1 mg/1 mg/kg/day, with a maximum possible dose of 20 mg of THC and 20 mg CBD per day (0.1mL/kg/day to a maximum of 2mL per day). This dose will be given in two divided doses.

The two-week Dose Titration Phase will be followed by a four-week maintenance phase with the maintenance dose being determined by the two-week titration phase.

Arm 2: CBD-Dominant Investigational Product with with a ratio of THC to CBD of 1:100. This Investigational Product contains CBD and THC at 100 mg/mL and 1 mg/mL respectively in an oral solution (Little Green Pharma). This will be upwardly titrated in the two-week Dose Titration Phase, with a dose range of CBD 1 mg/kg/day and THC 0.01mg/kg/day, up to a maximum of 200 mg/kg/day of CBD and 2 mg/kg/day of THC. The maximum possible dose is 200 mg of CBD and 2 mg of THC per day (0.1 mL/kg/day to a maximum dose of 2ml). This dose will be given in two divided doses.

The two-week Dose Titration Phase will be followed by a four-week maintenance phase with the maintenance dose being determined by the two-week titration phase.

Adherence to the trial drug will be monitored weekly by checking the volume of Investigational Product used/remaining each week, documentation of spillage of Investigational Product, completion of participant study diary and analysis of participant blood and urine samples. Participants will be required to return and unused or spoilt Investigational Products and empty bottles to their respective clinical trial pharmacy.

Descriptive analysis and frequency distributions will be generated from the participant's demographic and clinical characteristics. Linear Mixed Models will be used to assess changes in MSAS Global Disease Index, MSAS Total Score, MSAS physical symptom subscale and MSAS psychological symptom sub-scale over time and across treatment groups.
Results from pharmacokinetic analysis of CBD and THC will be correlated with patients' clinical status (age, weight, diagnosis) and dose.

Summary
Brief summary
This study is aimed at establishing tolerable and potentially effective doses of two medicinal cannabis products in paediatric palliative care.

Who is it for?
Participants may be eligible for this study if they are aged 6 months to 21 years, have advanced cancer (metastatic or locally advanced solid tumours, brain tumours or advanced hematological malignancies) and have been referred to or are known by the paediatric palliative service.

Study details
Participants will undergo baseline measurements, before being randomly allocated to either of two cannabis oil treatments which will be delivered daily for a total of 6 weeks. Participants will visit the clinic weekly to have their symptom burden assessed.

Results from this study will help determine clinical dosing of medicinal cannabis for relief of symptom burden in children with advanced cancer.
