Notes to Editors

Sativex®
Sativex®is an endocannabinoid modulator made of two actives - THC (delta-9-tetrahydrocannabinol) and CBD (cannabidiol) - which was developed and is manufactured by GW.

Sativex®is indicated as an add-on treatment for patients with moderate to severe spasticity due to multiple sclerosis (MS) who have not adequately responded to other anti-spasticity medications and who have demonstrated a clinically significant improvement in symptoms related to spasticity during an initial treatment testing periodi.

Sativex®contains active ingredients known as ‘cannabinoids’ which are extracted from the plant Cannabis Sativa grown and processed under strictly controlled conditions. Cannabinoids react with cannabinoid receptors that exist naturally throughout our body, including the brain.iiA receptor is a site located in a brain cell in which certain substances can stick or “bind” for a while. If this happens, this binding has an effect on the cell and the nerve impulses it produces, causing a ‘dimming-down’ of the spasticity symptom. In patients who respond to Sativex®, this is the effect that improves their spasticity symptoms and helps them cope with their daily activities.iii

Sativex®is approved in the UK, Spain, Canada and New Zealand in the treatment of spasticity due to MS. In addition, a further six European countries (Germany, Italy, Sweden, Denmark, Austria and the Czech Republic) have recently recommended Sativex® for approval and are expected to grant national licences in mid-2011.

Spasticity
Spasticity is a symptom defined by patients and carers as muscle spasms, seizing-up, stiffness and/or difficulty in moving muscles and it is one of the most common symptoms of MS, occurring in up to 75% of MS sufferers in the course of the disease. Spasticity can affect many aspects of the daily lives of patients with MS and is one of the main factors contributing to their distress and disability.iv

Cancer Pain
Sativex®recently commenced a Phase III trials programme in cancer pain, which is being performed in conjunction with GW’s licensing partner for Sativex®in the US, Otsuka Pharmaceutical Co. Ltd. The programme includes two Phase III randomised placebo-controlled multi-centre multinational trials as well as a long term extension study. Each Phase III trial will include approximately 370 patients and will evaluate the efficacy and safety of Sativex versus placebo over a 5 week treatment period.

Studies suggest that more than one-third of patients with cancer, and more than three-quarters of those with advanced disease, have chronic pain.  Large surveys indicate that optimal opioid therapy does not yield sufficient relief in a substantial proportion of these patients.
