GW has been researching cannabinoids since 1998 and has established a world leading position in the development of plant-derived cannabinoid therapeutics through our proven drug discovery and development processes, our intellectual property portfolio and our regulatory and manufacturing expertise. GW’s research explores the potential therapeutic application of cannabinoids and we have evaluated the pharmacology of a number of cannabinoids across a wide range of disease areas.

Our primary focus is on disorders of the central nervous system (CNS) including epilepsy. Our lead cannabinoid product candidate is Epidiolex®, a liquid formulation of pure plant-derived cannabidiol, or CBD, which is in development for the treatment of a number of rare childhood-onset epilepsy disorders.

We commercialized the world’s first plant-derived cannabinoid prescription drug, Sativex® (nabiximols), which is approved for the treatment of spasticity due to multiple sclerosis in 29 countries outside the United States.

We have a deep pipeline of additional cannabinoid product candidates which include compounds in development for epilepsy, glioma and schizophrenia.

GW is in a unique position to develop and manufacture plant-derived cannabinoid formulations worldwide at sufficient quality, uniformity and scale for the purposes of pharmaceutical development and to meet international regulatory requirements.
