Gilead Sciences Statement on U.S. Food and Drug Administration Advisory Committee’s Recommendation on Descovy for PrEP - Seite 2

The AMDAC is convened upon the request of FDA to review and evaluate safety and efficacy data of human products, including those for use in the treatment or prevention of HIV. While FDA is not bound by the committee’s recommendation, the recommendations made by advisory committees, including the panel deliberations and voting, may be considered by the agency in making its final decision on an application.

Descovy was approved in April 2016 for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 35 kg, in combination with other antiretroviral agents.

Descovy for the prevention of HIV is an investigational use that has not been determined to be safe or efficacious and is not approved anywhere globally.

IMPORTANT U.S. SAFETY INFORMATION AND INDICATION FOR THE USE OF DESCOVY FOR HIV TREATMENT
BOXED WARNING: POST TREATMENT ACUTE EXACERBATION OF HEPATITIS B

• Descovy is not approved for the treatment of chronic hepatitis B virus (HBV) infection and the safety and efficacy of Descovy have not been established in patients coinfected with HIV-1 and HBV. Severe acute exacerbations of hepatitis B have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued products containing emtricitabine (FTC) and/or tenofovir disoproxil fumarate (TDF), and may occur with discontinuation of Descovy. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue Descovy. If appropriate, initiation of anti-hepatitis B therapy may be warranted.

Warnings and precautions

• Immune reconstitution syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported.
• New onset or worsening renal impairment: Cases of acute renal failure and Fanconi syndrome have been reported with the use of tenofovir prodrugs. In clinical trials of FTC and tenofovir alafenamide with elvitegravir and cobicistat, there have been no cases of Fanconi syndrome or proximal renal tubulopathy (PRT). Do not initiate Descovy in patients with estimated creatinine clearance (CrCl) <30 mL/min. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue Descovy in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome.
