FOR IMMEDIATE RELEASE
Aviragen Therapeutics Provides Update on Phase 2a Trial of BTA585 for the Treatment of RSV Infections
ATLANTA, GA – May 26, 2016 – Aviragen Therapeutics, Inc. (NASDAQ: AVIR; formerly Biota Pharmaceuticals, Inc.), a pharmaceutical company that is developing the next generation of antivirals, today announced that it has voluntarily decided to delay further enrollment in the Phase 2a trial of BTA585 for the treatment of RSV infections being conducted in the U.K. This decision emanated from a lab report from one subject showing an increase of a cardiac enzyme level coupled with transient ECG changes, which led to a hospitalization of less than 24 hours. The subject’s ECGs were normal prior to hospitalization and the cardiac enzyme levels returned to baseline shortly thereafter.
The Company also reported that subsequent to the submission of the requisite safety report to the regulatory authorities, it received verbal communication from the U.S. Food and Drug Administration (FDA) that the investigational new drug application (IND) for BTA585 has been placed on clinical hold for studies being conducted in the U.S. under the IND. There are currently no trials of BTA585 being conducted under the IND. More specific written information from the FDA concerning the clinical hold is expected within 30 days.
“Patient safety is paramount to us, which led to our decision to voluntarily delay enrollment. We have proactively reached out to the Medicines and Healthcare Products Regulatory Agency (MHRA), the regulatory authority in the U.K., to discuss this event and any implications it may have on the continued clinical development of BTA585,” said Joseph M. Patti, PhD, President and Chief Executive Officer of Aviragen Therapeutics.
