Motif Bio Update on NDA Submission for Iclaprim

Motif Bio plc (AIM/NASDAQ: MTFB), a clinical-stage biopharmaceutical company specialising in developing novel antibiotics, today provided an update on the status and timeline for submission of its New Drug Application (NDA) to the U.S. Food & Drug Administration (FDA) for its targeted, Gram-positive investigational antibiotic, iclaprim, for the treatment of acute bacterial skin and skin structure infections (ABSSSI). In consultation with its advisers, the Company has decided that in order to ensure a complete and high quality submission, it would be prudent to take additional time and consequently, the Company now expects that the NDA will be submitted to the FDA during the second quarter of 2018. 

Graham Lumsden, Chief Executive Officer, said: "There are many components that go into an NDA submission and our aggressive timeline was contingent upon all outstanding items being completed to provide sufficient time to quality check and then publish the document. Most components are complete, but given the importance of the submission, we made the decision that it was in the best interests of the Company and all stakeholders to allow more time to ensure we submit the strongest possible application."

The person responsible for the release of this announcement on behalf of Motif Bio plc is Jonathan Gold, Interim Chief Financial Officer.

Notes to Editors

About Iclaprim 

Iclaprim is a novel investigational antibiotic that has a different and underutilised mechanism of action compared to other antibiotics. Iclaprim exhibits potent in vitro activity against Gram-positive clinical isolates of many genera of staphylococci, including methicillin-resistant Staphylococcus aureus (MRSA). Iclaprim is rapidly bactericidal, achieving 99.9% in vitro kill against MRSA within 4 to 6 hours of drug exposure versus 8 to 10 hours for vancomycin. To date, iclaprim has been studied in over 1,400 patients and healthy volunteers. In clinical studies iclaprim has been administered intravenously at a fixed dose with no dosage adjustment required in patients with renal impairment or in obese patients. The iclaprim fixed dose may, if approved, help reduce the resources required in hospitals since dosage adjustment by health care professionals is avoided and overall hospital treatment costs may be lower, especially in patients with renal impairment.

About Motif Bio

Motif Bio plc (AIM/NASDAQ: MTFB) is a clinical-stage biopharmaceutical company engaged in the research and development of novel antibiotics designed to be effective against serious and life-threatening infections in hospitalised patients caused by multi-drug resistant bacteria, including MRSA. The Company's lead product candidate, iclaprim, is being developed for high-risk MRSA patient populations. The first proposed indication, and near-term commercial opportunity, is for the treatment of ABSSSI, one of the most common bacterial infections, with 3.6 million patients hospitalised annually in the U.S. The Company believes that iclaprim may be suitable for first-line empiric therapy in ABSSSI patients, especially those with renal impairment, with or without diabetes. Unlike many standard of care antibiotics, iclaprim is only minimally cleared via the kidneys (

Iclaprim has an underutilised mechanism of action compared to other antibiotics. Clinical and microbiology data indicate iclaprim has a targeted Gram-positive spectrum of activity, low propensity for resistance development, fixed dose administration and favourable tolerability profile. Additionally, data support that the inactive metabolites of iclaprim clear through the kidneys. The Company also 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 was conducted to study iclaprim in patients with HABP. Iclaprim has been studied in an animal model of pulmonary MRSA infection which mimics the pathophysiology observed in patients with cystic fibrosis. Iclaprim has been granted orphan drug designation by the U.S. FDA for the treatment of Staphylococcus aureus lung infections in patients with cystic fibrosis.

Iclaprim has received Qualified Infectious Disease Product (QIDP) designation from the FDA together with Fast Track status. Upon acceptance by the FDA of a New Drug Application (NDA), iclaprim will receive Priority Review status and, if approved as a New Chemical Entity, 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.
