Dengue is the most prevalent mosquito-borne viral disease; endemic to 100 countries worldwide, with more than half the world’s populations at-risk
AT-752 is a novel, orally administered, direct-acting antiviral in Phase 2 development for treatment of dengue, showing potent in vitro and in vivo activity in preclinical studies and favorable safety and tolerability in a Phase 1 trial
AT-752, a novel, orally administered direct-acting antiviral derived from Atea’s purine nucleotide prodrug platform was designed for the treatment and prophylaxis of dengue. It works by impairing the dengue viral polymerase, which then inhibits replication of the virus. AT-752 is in Phase 2 clinical development and was generally well tolerated in a Phase 1 clinical study. In preclinical studies, AT-752 showed potent in vitro activity against all dengue serotypes, as well as potent in vivo antiviral activity in a small animal model.
“This Fast Track Designation underscores the urgent need for the development of effective treatments for this potentially severe viral disease as there are no currently approved treatments,” said Jean-Pierre Sommadossi, PhD, Chief Executive Officer and Founder of
“Dengue is the most prevalent mosquito-borne virus affecting up to 400 million people annually and is a substantial public health and economic burden worldwide. Dengue causes a severe generalized illness with fever which may require hospitalization and is associated with mortality. It is caused by an RNA virus which is transmitted by mosquitoes and may result in the potentially fatal clinical syndrome called dengue hemorrhagic fever,” said
About AT-752 Fast Track Designation
The FDA’s Fast Track program facilitates the expedited development and review of new drugs or biologics that are intended to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. Among other things, as a result of the Fast Track designation, Atea may benefit from more frequent communications with the FDA to discuss the development plan of AT-752 for the treatment of dengue virus infection and rolling review of any completed sections of a resulting New Drug Application (NDA).
About the AT-752 Clinical Program
Atea is currently conducting two clinical studies of AT-752. The first study is a global, randomized, double-blind, placebo-controlled Phase 2 trial in adult patients with dengue virus infection. The study is designed to evaluate the antiviral activity, safety and pharmacokinetics of multiple doses of AT-752 in areas where dengue is endemic. The second study is a human challenge study that is being conducted in
About Dengue
It is estimated that dengue accounts for up to 400 million infections a year globally, of which 100 million people get sick from the infection1 and 500,000 cases2 develop into life-threatening dengue hemorrhagic fever. Dengue infection is currently endemic in equatorial regions of the world, including
Four serotypes of dengue viruses (DENV1–4) are common and a fifth serotype has been isolated but is yet to be fully characterized. As dengue serotypes are sufficiently different antigenically, infection with one serotype will confer lifelong immune protection against that serotype only, with only temporary, partial cross-immunity to other serotypes following recovery. A person can therefore potentially be infected with each of the four dengue serotypes in their lifetime. Subsequent infections with other serotypes increase the risk of developing severe disease due to antibody-dependent enhancement (ADE).
