Frank Fish Lecture 2019

9 September 2019

This year's Frank Fish Lecture entitled “Cannabis: from a forgotten medicinal plant to new prescription cannabinoid medicines" will be given by Professor Benjamin J. Whalley on Wednesday 9th October at 5:00pm in the John Hanbury Lecture Theatre.


Historically, many anecdotal claims have been made for the use of cannabis in the treatment of a variety of diseases, including convulsive disorders such as epilepsy (Rosenberg et al, 2016). The behavioural pharmacology of the principal psychoactive component derived from cannabis, D9-tettrahydrocannabinol, in preclinical animal models and human epilepsies remains conflicted (Whalley, 2013). However, by virtue of its lack of affinity for cannabinoid receptors, the similarly abundant plant-derived cannabinoid, cannabidiol (CBD) is more amenable to study.

This presentation will summarise the findings from a programme of preclinical research of CBD in well-established, in vitro and in vivo, animal models of seizure initiated by GW in partnership with preclinical epilepsy specialists to demonstrate a broad, well tolerated and reproducible anticonvulsant profile. These findings led to the initiation of further partnerships between GW and leading paediatric and adult epilepsy clinicians to provide CBD (formulated as Epidiolex®) through an FDA authorised, Expanded Access Programme (EAP).

On the basis of initial open-label data from the EAP, GW initiated the GWPCARE Phase III clinical trial programme to assess CBD’s safety and efficacy for the treatment of seizures associated with childhood onset epilepsy disorders that are not adequately controlled with current antiepileptic drugs (AEDs).


The GWPCARE Phase III clinical trial programme includes six double-blind, placebo controlled studies evaluating the safety and efficacy of Epidiolex® as adjunctive therapy across four epilepsy indications. Here, data describing the preclinical evidence base for CBD’s non-clinical efficacy and underlying molecular mechanism, plus summary safety and efficacy results of Epidiolex® in the four Phase III trials to have thus far completed (GWPCARE1 & GWPCARE2: Dravet syndrome (DS); GWPCARE3 & GWPCARE4: Lennox-Gastaut syndrome (LGS)) will be presented.

GWPCARE studies were funded by GW Research, Ltd.
