Patients & Caregivers

Maintaining our focus on the potential benefit to patients has been a consistent driving force in GW’s research program and progress to date. GW is in a unique position to develop and manufacture consistent cannabinoid formulations worldwide at sufficient quality, uniformity, scale, and sophistication to meet international regulatory requirements.

Listening to patients has been at the heart of GW’s research efforts since our company’s founding in 1998. In the early years, GW’s research efforts in the UK focused on responding to the needs of patients with Multiple Sclerosis (MS) and resulted in the development and approval of Sativex® as a treatment for spasticity due to MS. In recent years, GW has responded to the needs of patients with early onset, severe and highly treatment-resistant forms of epilepsy, and has focused its efforts on the development of cannabidiol as a potential treatment option to address this important medical need. This focus has resulted in the groundbreaking approvals of EPIDIOLEX by the FDA in the U.S. and by the EMA under the brand name EPIDYOLEX. These medicines are available by prescription in these geographies.
