Brief summary

An open label trial evaluating the feasibility of a medicinal cannabis product for the symptoms associated with adult autism such as anxiety. The participants will complete a 3-week titration then stay on that dose for 12 weeks thereafter. There will be four weekly follow up visits in person and safety bloods will be taken. The trial is assessing if it is feasible to conduct a trial using medicinal cannabis in an adult Autism population. It is assumed that it will be feasible, and that medicinal cannabis will help reduce anxiety and improve quality of life.

Interventions

The medicinal cannabis product (FD-202) has been specifically made for this trial. A combination of cannabidiol (CBD), Cannabigerol (CBG) and tetrahydrocannabinol (THC) with added limonene was selected based on their individual properties. Dose: 1-1.2 ml per day. Duration: 84 days Mode of administration: oral ingestion Monitoring adherence: Is through self-report, participant diary and measurement of IMP The start dose of the titration is 0.2ml and this will be increased every 2 days by 0.2m

Duration: 84 days Mode of administration: oral ingestion Monitoring adherence: Is through self-report, participant diary and measurement of IMP The start dose of the titration is 0.2ml and this will be increased every 2 days by 0.2ml. The duration of the up-titration period is three weeks and will be until the participants reach there tolerated dose with a maximum of 1.2ml per day. If participants do not tolerate a dose, they will cease titration at the dose they tolerated and will remain on that dose for the remainder of the study period. The following active ingredients are contained in each milliliter of FD-202. FD-202 is dispensed in a 30 ml brown bottle with a 1ml syringe with 0.1ml graduations at a minimum to allow for accurate dosing: cannabidiol (CBD) 200mg/ml, cannabigerol (CBG) 50mg/ml, THC 5mg/ml, limonene 5mg/ml.
