Use of cannabidiol in the treatment of tuberous sclerosis complex

The present invention relates to the use of cannabidiol (CBD) for the treatment of tumours associated with Tuberous Sclerosis Complex (TSC). In particular the CBD was able to decrease the number and size of marker cells, pS6, in a zebrafish model of TSC. This is5 suggestive of a disease modifying effect whereby treatment with CBD could result in the reduction or prevention of the benign tumours that occur in TSC patients. Preferably the CBD used is in the form of a highly purified extract of cannabis such that the CBD is present at greater than 98% of the total extract (w / w) and the other components of the extract are characterised. In particular the cannabinoid tetrahydrocannabinol (THC) has been substantially 10 removed, to a level of not more than 0.15% (w / w) and the propyl analogue of CBD, cannabidivarin, (CBDV) is present in amounts of up to 1%. Alternatively, the CBD may be a synthetically produced CBD. In use the CBD is given concomitantly with one or more other drugs used in the treatment of TSC. Such drugs may include rapamycin and / or everolimus.
