GW Pharmaceuticals has announced financial results for the fourth quarter and full-year ended December 31, 2019. The British biopharmaceutical manufacturer in pole position in the commercialisation of cannabinoid prescription medicines said Epidiolex net product sales reached $104.5m in Q4 and $296.4m in the first full year of sales.

The financial report revealed a total revenue of US$109.1 million in Q4 and $311m for the full year.

“2019 was an exceptional and transformative year for GW, led by the successful launch of Epidiolex in the US and approval in Europe," said Justin Gover, GW’s Chief Executive Officer. 

"The positive impact this medicine has had on thousands of patients and their families provides a compelling foundation for continued growth in 2020,” he added 

Gover said GW is expecting 2020 to be an important year for its growing and developing product pipeline beyond Epidiolex as the company build on its knowledge in cannabinoid science. 

"We are focused on advancing nabiximols in the US in several indications and clinical programs with other potential products whilst continuing to bring Epidiolex to more patients in the US and Europe," he revealed.
