Its principal active cannabinoid components are the cannabinoids: tetrahydrocannabinol (THC) and cannabidiol (CBD). Each spray delivers a dose of 2.7 mg THC and 2.5 mg CBD. In May 2003 GW Pharmaceuticals and Bayer entered into an exclusive marketing agreement for GW's cannabis-based medicinal extract product, to be marketed under the brand name Sativex. "Bayer has obtained exclusive rights to market Sativex in the UK. In addition, Bayer has the option for a limited period to negotiate the marketing rights in other countries in European Union and selected other countries around the world." In April 2011, GW licensed to Novartis the rights to commercialise nabiximols in Asia (excluding China and Japan), Africa and the Middle East (excluding Israel).[4] AvailabilityIn June 2010, the Medicines and Healthcare products Regulatory Agency of the United Kingdom licensed nabiximols as a prescription-only medicine for the treatment of spasticity due to multiple sclerosis. This regulatory authorization represents the world's first full regulatory approval for the medicine. The spray is being marketed in the UK by Bayer Schering Pharma. Many people with MS cannot receive nabiximols due to local National Health Service (NHS) resistance to its funding;[5][6] but, in August 2014, the NHS in Wales agreed to fund Sativex for people with multiple sclerosis.[7] Nabiximols was also approved in Spain for MS spasticity in the second half of 2010 and was launched in that country in March 2011. It was approved in the Czech Republic in April 2011, in Germany in May 2011, in Denmark in June 2011 and in Sweden in January 2012 to people with MS who have not responded adequately to other medication for spasticity.[8] It has also been recommended for approval in Italy and Austria with formal approvals expected in these countries during 2011. In Spain and other European markets (excluding the UK), nabiximols will be marketed by Almirall. In Canada, nabiximols has been approved by Health Canada for the treatment of MS spasticity. It has also received a licence with conditions (NOC/c) for two additional uses: as adjunctive treatment for the symptomatic relief of neuropathic pain in multiple sclerosis,[9] and also for pain due to cancer.[10][11] Nabiximols is available in a number of countries as an unlicensed medicine, which enables doctors to prescribe the product to people who they consider may benefit. The product has been exported from the UK to a total of 28 countries to date. In February 2007, GW and Otsuka Pharmaceutical announced an exclusive agreement for Otsuka to develop and market the drug in the United States. The first large scale US Phase IIb trial, Spray Trial, for people with cancer reported positive results in March 2010. GW and Otsuka have now commenced the Phase III development of nabiximols in cancer pain. In December 2012, Sativex was approved in Poland.[12] In 2013, France legalized the use of cannabinoids in medicine, Sativex is the first one to be sold under prescription.[13] Nevertheless, at least until June 2016, this drug was never actually sold in pharmacies there.[14] EffectivenessOf the two preliminary Phase III studies investigating the treatment of people with MS, one showed a reduction of spasticity of 1.2 points on the 0–10 points rating scale (versus 0.6 points under placebo), the other showed a reduction of 1.0 versus 0.8 points. Only the first study reached statistical significance. The Phase III approval study consisted of a run-in phase where the response of individuals to the drug was determined. The responders (42% of subjects) showed a significant effect in the second, placebo controlled, phase of the trial.[15] A 2009 meta-analysis of six studies found large variations of effectiveness, with a – statistically non-significant – trend towards a reduction of spasticity.[16] A systematic review in 2014 by the American Academy of Neurology found that nabiximols was 'probably effective' for spasticity, pain, and urinary dysfunction, but wasn't supported for tremor.[17] Nabiximols has also been studied for cancer pain resistant to opioids. Adjuvant use was safe and effective in 3 trials for cancer pain,[18][19][20] however the drug failed to meet its primary endpoint for this purpose in its first Phase III trial.[21] Side effectsIn early clinical trials, nabiximols has generally been well tolerated.[22][23][24] The most common adverse effects in Phase III trials were dizziness (25%), drowsiness (8%) and disorientation (4%); 12% of subjects stopped taking the drug because of the side effects. No investigations regarding the potential for dependence are available, but such a potential is unlikely considering the pharmacological properties of the two components.[15] LicensingGW Pharmaceuticals were issued a unique license to cultivate cannabis for the manufacturing of Sativex in the UK, granting them the sole legal right to research in aerosolized cannabis derived therapeutics, which in April 2013 became commercially viable when the UK Government scheduled the Sativex formulation to part IV of the UK Drugs Act.[25] See also
