Motif Bio Announces FDA Acceptance of New Drug Application With Priority Review for Iclaprim for Treatment of Acute Bacterial Skin and Skin Structure Infections
NEW YORK, Aug. 14, 2018 (GLOBE NEWSWIRE) -- Motif Bio plc (AIM/NASDAQ: MTFB), a clinical-stage biopharmaceutical company specialising in developing novel antibiotics, today announced that the U.S. Food & Drug Administration (FDA) has accepted for filing the New Drug Application (NDA) for iclaprim, a targeted, Gram-positive investigational antibiotic, for the treatment of acute bacterial skin and skin structure infections (ABSSSI). This means that the FDA has determined that the application is sufficiently complete to perform a substantive review. The NDA has been granted Priority Review, and the FDA has set a target decision date under the Prescription Drug User Fee Act (PDUFA) of February 13, 2019.
“The NDA acceptance by the FDA is an important milestone for Motif Bio and reflects the dedication and commitment of our team who have worked tirelessly to accomplish this,” said Graham Lumsden, Chief Executive Officer of Motif Bio. “We believe that, if approved, iclaprim could be an important new treatment option for patients with serious skin infections. We look forward to working closely with the FDA as we move through the review process with the goal of bringing iclaprim to patients as quickly as possible.”
More than 3.6 million patients with ABSSSI are hospitalised annually in the U.S. It is estimated that up to 26% of hospitalised ABSSSI patients have renal impairment. Hospitalised patients with obesity, diabetes and/or poor kidney function are particularly vulnerable to vancomycin-associated kidney injury. Many standard of care Gram-positive antibiotics are not suitable for treatment of hospitalised ABSSSI patients with these conditions due to efficacy and/or safety issues.
The NDA includes data from two Phase 3 trials (REVIVE-1 and REVIVE-2) evaluating iclaprim for the treatment of patients with ABSSSI. In both trials, iclaprim achieved the primary endpoint of non-inferiority (NI) (10% margin) compared to vancomycin, the current standard of care, at the early time point (ETP), 48 to 72 hours after the start of administration of the study drug, in the intent-to-treat (ITT) patient population. Iclaprim also achieved NI (10% margin) at the test of cure endpoint, 7 to 14 days after study drug discontinuation, in the ITT patient population.
Iclaprim has received Qualified Infectious Disease Product (QIDP) designation from the FDA. If iclaprim is approved as a new chemical entity with QIDP designation, it will be eligible for 10 years of market exclusivity in the U.S. starting from the date of approval, under the Generating Antibiotic Incentives Now Act (the GAIN Act).
Iclaprim is a novel investigational antibiotic with a targeted Gram-positive spectrum of activity. In contrast to commonly used broad-spectrum antibiotics, this “precision medicine approach” is consistent with antibiotic stewardship principles which, among other things, seek to reduce the inappropriate use of broad-spectrum products to avoid the build-up of resistance and to lessen the impact on the microbiome of the patient.
Iclaprim has a different and underutilised mechanism of action compared to most other antibiotics. Following positive results from two Phase 3 trials (REVIVE-1 and REVIVE-2), a New Drug Application (NDA) has been submitted to the U.S. Food & Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI). To date, iclaprim has been studied in over 1,400 patients and healthy volunteers. Clinical and microbiological data indicate that iclaprim has a targeted Gram-positive spectrum of activity, low propensity for resistance development and favourable tolerability profile. 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. Many standard of care Gram-positive antibiotics are not suitable for hospitalised ABSSSI patients with renal impairment due to efficacy and/or safety issues.
About Motif Bio
Motif Bio plc (AIM/NASDAQ: MTFB) is a clinical-stage biopharmaceutical company focused on developing novel antibiotics for hospitalised patients and 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. Following positive results from two Phase 3 trials (REVIVE-1 and REVIVE-2), a New Drug Application (NDA) has been submitted to 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 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 preclinical development for this indication.
Iclaprim has received Qualified Infectious Disease Product (QIDP) designation from the FDA together with Fast Track status. If approved 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.
