Motif Bio Phase 3 Clinical Trial Finishes Patient Treatment Phase

NEW YORK, Jan. 30, 2017 -- Motif Bio plc (Motif) (NASDAQ:MTFB), (NASDAQ:MTFBW), a clinical stage biopharmaceutical company specializing in developing novel antibiotics, today announced that the last patient has finished the treatment phase in REVIVE-1, the Phase 3 clinical trial investigating the safety and efficacy of iclaprim in patients with acute bacterial skin and skin structure infections (ABSSSI).   

REVIVE-1 is a 600-patient double-blinded, global, multicenter trial, in patients with ABSSSI that compares the safety and efficacy of an 80mg intravenous dose of iclaprim with 15mg/kg intravenous vancomycin.  Treatments were administered every 12 hours for 5 to 14 days. Data read-out is expected in the second quarter of 2017.

Data read-out for REVIVE-2 is anticipated in the second half of 2017. Successful completion of the two REVIVE trials is expected to satisfy both US FDA and EMA requirements for regulatory submission for intravenous iclaprim in the treatment of ABSSSI.

Commenting on this milestone, Graham Lumsden, CEO of Motif Bio, said: “Thanks to the patients and investigators who participated in REVIVE-1, we remain on track to be able to share the first data from our Phase 3 clinical trials in 2Q17.  We believe that iclaprim, if approved, can be an important option for patients hospitalized with ABSSSI who also have kidney disease with or without diabetes. It is estimated that up to 26% of the 3.6 million ABSSSI patients hospitalized annually in the U.S. have kidney disease.”

About Iclaprim
Iclaprim is a novel antibiotic that has a different and underutilized mechanism of action compared to most other antibiotics.  Iclaprim exhibits potent 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 600 patients and healthy volunteers.
