ViiV Healthcare, the global specialist HIV company majority-owned by GSK, with Pfizer Inc. and Shionogi Limited as shareholders, today announced that it has filed patent infringement litigation against Gilead Sciences Inc. over bictegravir in the United States and Canada. The United States case is filed in the U.S. District Court for the District of Delaware and the patent is U.S patent No. 8,129,385. The Canadian case is filed in the Canadian Federal Court in Toronto and the patent isCanadian Patent No. 2,606,282.

ViiV Healthcare will seek to prove that Gilead Sciences Inc’s triple combination HIV drug containing the HIV integrase inhibitor bictegravir infringes ViiV Healthcare’s patent covering ViiV Healthcare’s dolutegravir and many other compounds that include dolutegravir’s unique chemical scaffold.

Intellectual property protections are critical for the life-sciences industry, allowing companies to make a return on their investment, which in turn enables research-based companies to put new funding into research and development. It is this cycle which continues to result in the development of new and much needed treatments for people living with HIV. ViiV Healthcare will therefore seek financial redress for patent infringement.

 

  • ViiV Healthcare is an independent, global specialist HIV company that is committed to delivering innovative new options for the care and treatment of people living with HIV/AIDS.
  • Established in 2009 through a unique partnership between GSK and Pfizer, ViiV Healthcare combines the HIV expertise of GSK, Pfizer and Shionogi, who joined in 2012 following a long-term collaboration on the joint development of several novel integrase inhibitors.
  • ViiV Healthcare is represented by leading intellectual property trial firms in the recently filed cases.   Desmarais LLP is trial counsel in the U.S. litigation and Bereskin Parr represents ViiV Healthcare in the Canadian action.
  • Since approval in the United States in 2013, dolutegravir has become the leading core agent in the U.S. with demonstrated efficacy and safety across a broad range of populations including five superiority studies vs competitors.
  • More than half a million people with HIV worldwide are currently taking dolutegravir. Physicians trust dolutegravir as a core agent in treating the entire spectrum of patients living with HIV, including those who have failed other integrase inhibitors and have limited options for therapy.
  • There is currently no cure for the disease and people living with HIV will require treatment for the rest of their life.
