Case Summary

An anonymous, non-contactable complainant, who described him/herself as a health professional, alleged that GW Pharmaceuticals had promoted Epidiolex (cannabidiol) at a meeting in January 2018 before the medicine had been granted a marketing authorization.

The complainant alleged that the GW Pharmaceuticals exhibition stand displayed Epidiolex material and that a named employee introduced the medicine as a new treatment for paediatric patients with Dravet Syndrome and patients with Lennox-Gastaut Syndrome and stated that the medicine had been licensed by the European Medicines Agency (EMA) and would soon be available in the UK. The complainant had since found out that Epidiolex had not been approved by the EMA; the information from GW Pharmaceuticals was misleading.

The detailed response from GW Pharmaceuticals is given below. The Panel noted that when the meeting was held, Epidiolex did not have a marketing authorization although licences had been applied for in the EU and US. GW Pharmaceuticals had submitted that it expected a decision from the European Commission for Epidiolex in mid-2019.

The Panel noted that the named GW Pharmaceuticals employee stated that the company’s presence at the meeting comprised a small medical booth staffed by him/her and another member of the UK medical team. The booth was intended to provide a nonpromotional presence to demonstrate the company’s commitment to research and development, its corporate awareness as a pharmaceutical development company, nonproduct specific disease awareness, and information on GW Pharmaceuticals’ main research activities including cannabinoid medicines. Copies of the materials available at the booth were provided; none mentioned Epidiolex by name. The Panel noted that it was an accepted principle under the Code that a product could be promoted without its name ever being mentioned.

Photographs of the exhibition stand showed material including the infographics that were striking and very prominently placed and thus highly visible to delegates visiting the stand. The material discussed various aspects of Dravet Syndrome and Lennox Gastaut Syndrome and highlighted that current therapeutic options were inadequate. Material for Lennox-Gastaut Syndrome stated ‘Up to 80% of patients are refractory to anti-epileptic drug therapy’ and that for Dravet Syndrome stated ‘Only 16% of patients experience complete resolution in their seizures. All seizure types extremely resistant to treatment’. In the Panel’s view, these statements would, on the balance of probabilities, solicit questions about the company’s pipeline products.

A leaflet entitled ‘A World leader in the development of cannabinoid medicines’ discussed GW Pharmaceuticals’ commitment to cannabinoid treatments. The final page gave more details describing the cannabinoid development pipeline by indication under investigation and phase of clinical study. Seven neuroscience pipeline indications were listed and it was stated that Dravet Syndrome and Lennox-Gastaut Syndrome had completed Phase 3 trials. It was further stated that the company’s ‘lead cannabinoid’ had received orphan drug designation in these indications. The Panel noted that whilst Epidiolex was not named, sufficient information about it was given such that it was indirectly identified and on the balance of probabilities the material would solicit questions about the company’s ‘lead cannabinoid’.

In the Panel’s view, the cumulative effect of the material, including the reference to the company’s ‘lead cannabinoid’, meant that the exhibition stand promoted a medicine prior to the grant of its marketing authorization. Breaches of the Code were ruled including a breach of Clause 2.

The Panel noted that the materials had a promotional appearance and considered that they went beyond disease awareness information and/or non-promotional information about the company and its research interests.

The Panel noted the complainant’s comments about statements allegedly made by the named employee ie that Epidiolex was a new treatment for paediatric patients with Dravet Syndrome and patients with Lennox-Gastaut Syndrome and that it had been licensed by the EMA and would soon be available in the UK. GW Pharmaceuticals denied that such comments had been made. The Panel noted that it was often impossible in complaints based on one party’s word against the other to determine precisely what had happened. The complainant had the burden of proving his/her complaint on the balance of probabilities. The complainant was non-contactable and it was not possible to ask him/her for further information. The Panel had to make a ruling on the evidence before it. The Panel noted its comments above about responses to unsolicited enquiries and also the statement of the company employee manning the booth in relation to training, the nature of queries received at the exhibition stand, and whether he/she would have responded as alleged. The Panel also noted the detailed briefing for staff to use at conferences in response to unsolicited requests advising that discussions with health professionals must be reactive and in response to the requested information. Staff were advised to narrowly tailor the response to the level of the question posed. The company’s report on interactions at the conference did not closely mirror the complainant’s allegation. In relation to the alleged comments made at the exhibition stand, it was impossible to determine where the truth lay and the Panel accordingly ruled no breach of the Code.
