Motif Bio plc (LON:MTFB), a clinical-stage biopharmaceutical company specialising in developing novel antibiotics, has today announced that the Company has received a Notice of Allowance from the United States Patent and Trademark Office for United States Patent Application Nos. 15/586,021 and 15/586,815. The claims relate to the use of iclaprim to treat patients with bacterial infections, including but not limited to acute bacterial skin and skin structure infections, hospital-acquired bacterial pneumonia and Staphylococcus aureus lung infections in patients with cystic fibrosis. The two method of use patents will expire in November 2037.
Graham Lumsden, Chief Executive Officer of Motif Bio, said: “These U.S. patents provide additional exclusivity for iclaprim in the treatment of bacterial infections well into 2037. We are actively building our intellectual property portfolio in the U.S. and other key markets around the globe.”
Motif Bio plc 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.
