ATLANTA, Aug. 20, 2015 (GLOBE NEWSWIRE) -- Biota Pharmaceuticals, Inc. (NASDAQ:BOTA) ("Biota" or the "Company"), a biopharmaceutical company focused on the discovery and development of direct-acting antivirals that address infections that have limited therapeutic options, announced today that it has commenced dosing in a 50-subject, randomized, placebo-controlled, Phase 1 single ascending dose (SAD) trial to evaluate the safety and pharmacokinetics (PK) of BTA585 in healthy volunteers. BTA585, a potent inhibitor of viral entry into cells, is an orally bioavailable compound in clinical development for the treatment of respiratory syncytial virus (RSV) infections in children, the elderly and immunocompromised patients.
"The initiation of this study represents a major milestone for Biota as we continue to build our promising RSV antiviral development program," remarked Joseph M. Patti, PhD, president and chief executive officer at Biota. "Given today's limited RSV therapeutic options, both approved and in clinical development, we believe that BTA585 has the potential to reduce the significant morbidity and mortality associated with acute RSV A & B infections in both children and adults."
"In addition to BTA585, we are also advancing our RSV non-fusion inhibitor program and plan to have a lead clinical candidate selected for Investigational New Drug (IND)-enabling studies by mid-2016. Similar to current treatment paradigms for HCV and HIV, we believe that attacking the virus with multiple compounds that exhibit different mechanisms of action could be effective as combination therapy for patients infected with RSV," continued Dr. Patti.
The Phase 1 SAD trial has five dose level cohorts ranging from 50 mg to 500 mg. In order to evaluate the effect of food on the plasma PK of BTA585, one cohort will initially be dosed fasted then with food. Following a safety assessment of the initial dose level cohorts of the SAD trial, the Company plans to begin dosing in a Phase 1 multiple ascending dose study in the fourth quarter of 2015.
