LONDON and CARLSBAD, Calif., Jan. 11, 2021 (GLOBE NEWSWIRE) -- GW Pharmaceuticals plc (Nasdaq: GWPH), the world leader in the science, development, and commercialization of cannabinoid prescription medicines, today reported preliminary, unaudited net product sales for the fourth quarter and full year 2020 and key priorities for 2021. Justin Gover, GW’s Chief Executive Officer, expects to discuss these updates as part of a webcast presentation at the 38th Annual J.P. Morgan Healthcare Conference on Tuesday, Jan. 12th at 10:00 a.m. ET.

“Epidiolex sales increased by over 70% in 2020 despite the challenges of COVID-19, reflecting the positive impact this medicine has on patients as well as the performance of our commercial team. We remain encouraged by our patients’ experience on this product, as demonstrated by high persistence and refill rates. This, combined with our expansion of payer coverage and the recently approved Tuberous Sclerosis Complex indication, leads us to expect continued strong growth in 2021 in both the US and Europe,” said Justin Gover, GW’s Chief Executive Officer. “Our goals in 2021 include driving further Epidiolex growth and advancing multiple US pivotal trials for nabiximols in the treatment of MS spasticity, with the first data readout expected this year. In addition to our previously announced pipeline activities, we are leveraging our world leadership in cannabinoid science to design and synthesize novel cannabinoid molecules and expect our first novel product candidate to enter the clinic in 2021.”
