Melinta’s innovative project brings to 10 the number of new classes in the CARB-X portfolio; it has been more than half a century since the last new class was approved
(BOSTON, MA) – May 7, 2018 – CARB-X is teaming up with Melinta Therapeutics (NASDAQ: MLNT) to support the development of a new class of antibiotic called pyrrolocytosine to treat the most serious drug-resistant bacterial infections. Melinta will receive an initial award of up to $2.3M, with the possibility of $3.9M more from CARB-X based on the achievement of certain project milestones.
“This funding aims to speed the development of an exciting new class of antibiotics to treat patients with life-threatening Gram-negative infections and to enhance global health security. It’s vital we accelerate the discovery of new and innovative approaches to address the rising threat of drug resistance; it has been more than half a century since the last new class was approved,” said Kevin Outterson, Executive Director of CARB-X. “The projects in the portfolio are in the early stages of research. But if successful, these innovative projects hold great potential in the treatment of serious infections and in the fight against the rise of drug-resistant bacteria.”
“Our structure-based design efforts to create and optimize the pyrrolocytosine class of antibiotics have shown exciting promise, with several compounds demonstrating comprehensive activity and preclinical effect across the full set of bacterial “superbugs”,” said Erin Duffy, Ph.D., Chief Scientific Officer at Melinta. “We believe this new class of antibiotics could be transformational in the fight against these urgent threats. The support and resources available through CARB-X will provide important assistance as we move to advance one or more pyrrolocytosines into clinical development.”
Melinta’s novel pyrrolocytosine compounds are part of the company’s ESKAPE Pathogen Program, a program based on Melinta’s proprietary drug discovery platform focused on developing breakthrough antibiotics for bacterial “superbugs” by targeting the bacterial ribosome. The pyrrolocytosines have been designed de novo, from the ground up, in a site not previously exploited by the many successful classes of antibiotics that target the ribosome. They are being developed to optimize properties that allow them to get in and stay in bacterial cells. The novelty in chemistry and binding, combined with the optimized properties, have translated to date into an in vitro activity profile that is not affected by current resistance mechanisms of concern. The pyrrolocytosines have also been shown in preclinical studies to be active against multidrug-resistant pathogens on the Antibiotic Resistant Threats in the United States report published by the Centers for Disease Control and Prevention (CDC) in 2013, including all of the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species).
The CARB-X award will help Melinta advance the most promising pyrrolocytosine compounds through preclinical optimization and into clinical development, where ultimately their efficacy and safety in humans may be examined.
The CARB-X portfolio is the world’s largest and most scientifically diverse portfolio of early development products, including new classes of antibiotics and other therapeutics, vaccines, diagnostics and devises, to address serious drug-resistant bacterial infections and other difficult-to-treat infections. There are 10 new classes of antibiotics in the portfolio, and if only one of them successfully reaches patients, it could potentially be the first new class of antibiotic to be approved for the treatment of Gram-negative bacteria since 1962. CARB-X, which stands for Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator, funds 32 projects in 7 countries and is working to expand its pipeline with great science from around the world.
Since it was established in 2016, CARB-X has announced awards totaling $82.1 million, plus an additional $111.4 million if project milestones are met, to speed the development of life-saving products. These funds are in addition to investments made by the companies themselves.
The world urgently needs new antibiotics to treat drug-resistant bacteria. According to the World Health Organization (WHO), an estimated 700,000 people die each year around the world from bacterial infections – and that number is on the rise. The last new class of antibiotics approved to treat Gram-negative bacteria was discovered in the early 1960s. Since then, resistance to antibiotics has been on the rise.
CARB-X is a partnership between the UK charity Wellcome Trust, the US Department of Health and Human Services Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response (ASPR), and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).
CARB-X is one of the world’s largest public-private partnership devoted to early development antibacterial R&D. Funded by ASPR/BARDA and Wellcome Trust, with in-kind support from NIAID, CARB-X is investing up to $455 million from 2016-2021 to support innovative therapeutics, vaccines, rapid diagnostics and devices to treat drug-resistant bacterial infections. CARB-X focuses on high priority drug-resistant bacteria, especially Gram-negatives. CARB-X operates through Boston University. Other partners include RTI International, the Broad Institute of Harvard and MIT, MassBio, and the California Life Sciences Institute (CLSI). http://www.carb-x.org/.
