Alderley Park, Cheshire, U.K. Infex Therapeutics, a leading anti-infectives specialist, is pleased to announce that the U.S. Food and Drug Administration (“FDA”) has granted Qualified Infectious Disease Product (“QIDP”) designation to MET-X, the Company’s broad spectrum Metallo-beta-lactamase (“MBL”)-inhibitor.
MET-X is a resistance bypass treatment which targets Gram-negative Enterobacterales. These pathogens produce MBL enzymes to deactivate beta-lactam antibiotics and evade antibiotic clearance of disease. MET-X blocks MBL resistance, restoring antibiotic activity. The drug is being developed to be one of the first broad-spectrum MBL inhibitors to address a wide range of bacterial species and drug-resistant strains. The treatment has shown best-in-class performance in animal studies to date and is currently undergoing pre-clinical safety evaluation with clinical studies planned for 2023. The management of antibiotic resistance in Gram-negative Enterobacterales is a World Health Organisation (“WHO”) critical priority.
QIDP designation is a U.S. incentive scheme designed to encourage the development of innovative new drugs to treat serious or life-threatening infections. The designation gives MET-X an accelerated FDA regulatory pathway, including priority review, fast-track designation and an additional five years of market exclusivity upon regulatory approval.
Antimicrobial resistance (“AMR”) is a serious and growing global threat to public health: the WHO has declared it as one of the top 10 global public health threats facing humanity. According to a recent study in The Lancet, AMR killed over 1.27 million people in 20191, more than HIV and malaria. By 20502 the annual number of deaths caused by AMR is projected to reach c. 10 million people, with an estimated US$1.2 trillion a year in additional health expenditure required to address the issue3.
Dr Pete Jackson, Executive Director of Infex, commented: “The award of the FDA’s QIDP designation is a significant step forward in the development of MET-X and is a strong endorsement and validation of the programme. Importantly, it provides MET-X with a fast-tracked U.S. regulatory pathway and an additional five-year exclusivity period.
“The world desperately needs new drugs to tackle the growing global threat of AMR, which is placing a significant burden on healthcare systems. The QIDP designation underlines MET-X’s potential to provide a vitally important, new and effective therapeutic option to patients with drug resistant infections who have exhausted all current treatment options.”
