U.S. Army-funded research project to Evaluate Iclaprim

24 October 2019

Motif Bio plc

(“Motif Bio” or the “Company”)

Motif Bio plc (AIM/Nasdaq: MTFB), a clinical-stage biopharmaceutical company specialising in developing novel antibiotics, today announced that the Company has signed an agreement with the Walter Reed Army Institute of Research (WRAIR) to conduct pre-clinical testing to evaluate novel combinations with iclaprim to improve safety and efficacy administered by a novel enhanced aerosol technology.

The aerosol technology allows delivery of antibiotics painlessly and rapidly into skin and soft tissue with low-pressure and focused delivery. The research is being funded through a grant from the U.S. Department of Defense – Congressionally Directed Military Infectious Diseases Research Program to evaluate the potential of using such a drug-device combination for wound care and to prevent and treat wound infections on the battlefield. The work will be led by Dr. Daniel Zurawski, Ph.D., Chief, Pathogenesis and Virulence, WRAIR/Wound Infections Dept./Bacterial Diseases Branch.

David Huang, M.D., Ph.D., Chief Medical Officer of Motif Bio, said: “When a wound becomes infected, it is critical to provide safe and effective treatment as fast as possible. The data generated from Dr. Zurawski’s research will be important in understanding whether iclaprim delivered locally could play a role in treating battlefield wound infections.”

This announcement contains inside information for the purposes of Article 7 of Regulation (EU) 596/2014.

About Motif Bio
Motif Bio plc (AIM/NASDAQ: MTFB) is a clinical-stage biopharmaceutical company focused on developing novel antibiotics designed to be effective against serious and life-threatening infections caused by multi-drug resistant Gram-positive bacteria, including MRSA. The Company’s lead product candidate is iclaprim. Motif Bio is seeking approval of iclaprim from the U.S. Food & Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI). More than 3.6 million patients with ABSSSI are hospitalised annually in the U.S. It is estimated that up to 26% of hospitalized ABSSSI patients have renal impairment.

The Company also has plans to develop iclaprim for hospital acquired bacterial pneumonia (HABP), including ventilator associated bacterial pneumonia (VABP), as there is a high unmet need for new therapies in this indication. A Phase 2 trial in patients with HABP has been successfully completed and a Phase 3 trial is being planned. Additionally, iclaprim has been granted orphan drug designation by the FDA for the treatment of Staphylococcus aureus lung infections in patients with cystic fibrosis and is in pre-clinical development for this indication.

Iclaprim received Qualified Infectious Disease Product (QIDP) designation from the FDA together with Fast Track status for the ABSSSI indication. If approved for the ABSSSI indication as a New Chemical Entity, iclaprim will be eligible for 10 years of market exclusivity in the U.S. from the date of first approval, under the Generating Antibiotic Incentives Now Act (the GAIN Act). In Europe, 10 years of market exclusivity is anticipated. Motif is also building a patent estate to provide additional protection for iclaprim and has two U.S. method of use patents issued that will expire in 2037.
