NEW YORK, Aug. 19, 2019 (GLOBE NEWSWIRE) -- Motif Bio plc (AIM/Nasdaq: MTFB), a clinical-stage biopharmaceutical company specialising in developing novel antibiotics, today announced that the Company will be utilising NIAID’s1 suite of preclinical services through JMI Laboratories to evaluate iclaprim against Listeria monocytogenes, a Gram-positive bacteria causing food-borne, life-threatening infections. The study, to be funded by NIAID, follows earlier in vitro testing in which iclaprim was ≥32-fold more potent than standard-of-care ampicillin and demonstrated consistent extracellular as well as intracellular activity against L. monocytogenes2.
Listeriosis is a rare but serious infection usually caused by eating food, such as cheese and other dairy products, deli meat and produce that has been contaminated with L. monocytogenes. An estimated 1,600 people in the U.S. get listeriosis each year, and the infection is most likely to sicken pregnant women and their newborns, adults aged 65 or older, and people with weakened immune systems. The disease can lead to septicaemia or meningitis, and about 260 people in the U.S. die from listeriosis annually. If treatment is required, patients are generally given IV antibiotics – ampicillin alone or in conjunction with another antibiotic.
David Huang, M.D., Ph.D., Chief Medical Officer of Motif Bio, said: “Listeriosis is a potentially life-threatening infection for which more effective treatment options are needed. If the results of this study confirm that iclaprim has potent activity against L. monocytogenes, we believe that iclaprim could be a potentially useful treatment option and would warrant further study.”

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. In February 2019, the Company received a Complete Response Letter (CRL) related to the New Drug Application (NDA) for iclaprim for the treatment of ABSSSI. Additional information regarding the CRL can be found in Motif Bio’s Annual Report on Form 20-F filed with the SEC on April 15, 2019. Minutes from a meeting with the FDA to discuss the points raised in the CRL were received in June 2019 and indicated that an additional clinical trial will be required prior to granting marketing approval to address the Agency’s continued concerns about potential liver toxicity. The Company was encouraged by the FDA to put forth a proposal for a future study and submitted such a proposal for review in July 2019. Motif Bio has been granted a meeting, scheduled for September 19, 2019, with the Agency to discuss the proposed patient population and study design.
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.
