ATLANTA, April 11, 2016 (GLOBE NEWSWIRE) -- Biota Pharmaceuticals, Inc. (NASDAQ:BOTA), a biopharmaceutical company focused on the discovery and development of direct-acting antivirals that address infections that have limited therapeutic options, today announced the initiation of its Phase 2a challenge study of BTA585, an oral fusion inhibitor in development for the treatment and prevention of respiratory syncytial virus (RSV) infections. BTA585 has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for RSV infections in infants, young children and adults.
“We are pleased to initiate this Phase 2a challenge study just seven months after initiating our first-in-man Phase 1 study with BTA585. The rapid progress of the program has been encouraging and reinforces our commitment to developing a safe and efficacious treatment for the millions of children that suffer annually from serious RSV infections,” commented Joseph Patti, PhD, president and chief executive officer of Biota. “We expect data readout from this challenge study later this year, which will help inform our plans for a Phase 2b natural exposure trial in this important indication.”
The double-blind, placebo-controlled, Phase 2a trial is designed to evaluate the safety, pharmacokinetics, and antiviral activity of orally dosed BTA585 in healthy volunteers challenged intranasally with RSV. Following a positive test for RSV or five days after challenge, approximately 60 healthy adults will be randomized to receive either BTA585 or placebo, dosed twice daily for seven days and monitored for 28 days. The primary endpoint of the study is area under the curve for the viral load in nasal wash among subjects who test positive for RSV prior to dosing. Secondary efficacy endpoints include measures of RSV clinical symptoms and other viral load endpoints such as peak viral load and time to cessation of virus detection. The study includes assessment of PK levels in both plasma and nasal wash.
About Respiratory Syncytial Virus (RSV)
RSV is a major cause of acute upper (colds) and lower (pneumonia and bronchiolitis) respiratory tract infections in infants, young children, and adults. Each year in the United States, RSV accounts for an estimated 2.1 million medical visits in children under the age of five, with many of the children afflicted requiring hospitalization. At the present time there is no effective vaccine to prevent or recommended therapy to treat RSV infections.
