Oragenics, Inc. Receives Clearance to Enroll Patients in Belgium into Its Phase 2 Clinical Trial of AG013 for Oral Mucositis

TAMPA, Fla.--(BUSINESS WIRE)-- Oragenics, Inc. (NYSE American: OGEN), a leader in the development of new antibiotics against infectious diseases and effective treatments for oral mucositis (“OM”), today announced it has received clearance to enroll patients residing in Belgium from the Belgian Health Authority, The Federal Agency for Medicines and Health Products (FAMHP), into its Phase 2 clinical trial of AG013, a live biotherapeutic product for the potential prevention and treatment of OM.

“Enrolling patients outside of the United States provides an expansive patient base from which to draw for our trial of AG013, allowing us to more rapidly reach our goal of enrolling between 160-180 evaluable patients,” stated Alan Joslyn, Ph.D., president and CEO of Oragenics, Inc. “The combination of the expanded number of clinical sites in the United States and Europe along with recent warrant exercises generating proceeds of approximately $9.5 million, should enhance our ability to complete the clinical study in 2019.”

The ongoing Phase 2 trial is a double-blind, placebo-controlled, two-arm, multi-center trial, in which approximately 200 patients will be randomized in a 1:1 ratio to receive either AG013 or placebo. The purpose of the study (NCT03234465) is to evaluate the safety, tolerability and efficacy of topically administered AG013 compared to placebo for reducing the incidence and severity of OM in patients undergoing traditional chemoradiation for the treatment of head and neck cancer. Key measures include duration, time to development, and overall incidence of OM (using a World Health Organization scale) during the active treatment phase, which begins from the start of chemoradiation therapy and ends two weeks following its completion.

AG013, which has been granted Fast Track designation with the U.S. Food and Drug Administration and orphan drug status in Europe, is an Intrexon Actobiotics therapeutic candidate formulated to deliver the therapeutic molecule, human Trefoil Factor 1, to the mucosal tissues in the oral cavity in a convenient oral rinsing solution. Trefoil Factors are a class of peptides involved in the protection of gastrointestinal tissues against mucosal damage and play an important role in these tissues subsequent regeneration. The compound was designed by the company’s strategic partner, Intrexon Actobiotics NV, a wholly-owned subsidiary of Intrexon Corporation (NYSE: XON) whereby Oragenics, Inc. holds an exclusive world-wide license.
