A long-running legal challenge that bictegravir was so similar to dolutegravir that Gilead infringed the ViiV patent has now been resolved. [1, 2]<\/span><\/strong><\/p>\n<\/div>\n

\n

In a press release on 1 February 2022, Gilead announced that it will pay a one-time payment of $1.25 billion for ViiV to withdraw all claims. Gilead will also pay “an ongoing royalty payment of 3%\u00a0until 2027\u00a0on future sales of Biktarvy and on the bictegravir component of any future bictegravir-containing products sold in the US.”<\/span><\/p>\n

In 2020, Gilead sales were more than $6b in the US with 17% growth in 2021. [2, 3]<\/p>\n

\n

This is a relatively small settlement. Gilead year-to-date sales including 3Q2021 were $11.8b. Biktarvy is the most widely prescribed US treatment with a patent claim until 2030. Gilead drugs account for 75% of US market share. [3]<\/span><\/strong><\/p>\n

Dolutegravir was approved in the US in August 2013 and Biktarvy (containing bictegravir) was approved in February 2018.<\/span><\/strong><\/p>\n<\/div>\n

\n

The similarity between these two integrase inhibitors is so close that the side effect profile of dolutegravir \u2013 which has been described for an additional five years \u2013 is believed by many researchers to also apply to bictegravir. unless proved otherwise.<\/span><\/strong><\/p>\n<\/div>\n
