-- Vemlidy Demonstrated Similar Efficacy with Improvements in
Renal and Bone Laboratory Safety Parameters Compared to Viread in Phase
3 Studies --
FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the Committee
for Medicinal Products for Human Use (CHMP), the scientific committee of
the European Medicines Agency (EMA), has adopted a positive opinion on
the company’s Marketing Authorization Application (MAA) for Vemlidy®
(tenofovir alafenamide, TAF) 25 mg, an investigational, once-daily
tablet for the treatment of chronic hepatitis B virus (HBV) infection in
adults and adolescents (= 12 years and = 35 kg body weight). The data
included in the application support the use of TAF in treatment-naïve
and treatment-experienced adults and adolescents with HBeAg-negative and
HBeAg-positive HBV infection.
TAF is a novel, targeted prodrug of tenofovir that has demonstrated
antiviral efficacy similar to and at one-tenth the dose of Gilead’s
Viread® (tenofovir disoproxil fumarate, TDF) 245 mg. Data
show that because TAF has greater plasma stability and more efficiently
delivers tenofovir to hepatocytes compared to TDF, it can be given at a
lower dose, resulting in less tenofovir in the bloodstream. As a result,
TAF improved certain renal and bone laboratory safety parameters
compared to TDF in clinical trials.
The CHMP’s recommendation will now be reviewed by the European
Commission, which has the authority to approve medicines for use in the
28 countries of the European Union, Norway and Iceland.
The MAA for TAF includes data from two international Phase 3 studies
(Studies 108 and 110) in 1,298 treatment-naïve and treatment-experienced
patients with HBV infection. Study 108 randomized 425 HBeAg-negative
patients to receive either TAF or TDF, and Study 110 randomized 873
HBeAg-positive patients to receive either TAF or TDF. The full data from
Studies 108 and 110 were presented at the International Liver Congress™
(ILC) earlier this year.
TAF as a single-agent for HBV is an investigational product and its
safety and efficacy have not yet been established.
