CARB-X funds ContraFect to develop a new class of antibiotics to treat serious infections caused by Gram-negative ESKAPE superbugs

ContraFect’s new class of phage-encoded lytic agents called ‘amurins’ aims to treat the deadliest drug-resistant Gram-negative pathogens

(BOSTON, MA) – CARB-X is awarding ContraFect Corporation (Nasdaq:CFRX) of Yonkers, New York, USA, up to $1.75 million in non-dilutive funding with the possibility of $5.19 million more if certain project milestones are met, to develop novel antibiotics to treat serious life-threatening infections caused by Gram-negative ESKAPE pathogens. This is ContraFect’s second antibacterial project to earn CARB-X funding.

“ContraFect’s amurin project is an exciting new approach to treating infections caused by the deadliest drug-resistant Gram-negative bacteria and, if approved by the FDA, would represent a new drug class,” said Kevin Outterson, Executive Director of CARB-X and Boston University law professor. “The projects in the Powered by CARB-X portfolio are in the early stages of development, but if successful, they offer tremendous hope in the fight against drug resistance. The world urgently needs new products to treat life-threatening infections caused by drug resistant superbugs.”

Cara Cassino, M.D., ContraFect’s Chief Medical Officer, remarked, “We are excited to unveil amurins, our proprietary new class of antimicrobials to tackle antibiotic resistance, one of the most important challenges facing medicine today. Emerging strains of pan- and extreme- drug resistant (PDR and XDR) Gram-negative bacteria are resistant to all but a few conventional antibiotic treatments of last resort. These infections have high mortality rates, are associated with substantial morbidity among survivors and require lengthy hospitalizations and significant societal and healthcare cost. Amurins are highly differentiated from conventional antibiotics through their novel mechanism of action and potent spectrum of activity against the most threatening Gram-negative pathogens. We look forward to advancing development of this promising new class of antimicrobial agents with the support of CARB-X.”

ContraFect’s new class of amurins are phage-encoded lytic agents which exhibit potent, broad spectrum activity against Gram-negative ESKAPE pathogens (P. aeruginosa, Klebsiella pneumoniae, Enterobacter cloacae, and Acinetobacter baumannii) as well as Escherichia coli and Salmonella typhimurium. Amurins also have shown ability to clear biofilms and act synergistically with a range of standard of care anti-Gram-negative antibiotics.

CARB-X is supporting the development of amurins for the treatment of acute exacerbations of cystic fibrosis caused by multidrug-resistant Gram-negative pathogens and potentially for the treatment hospital-acquired bacterial pneumonia, including ventilator-associated bacterial pneumonia and associated bacteremia. The project is currently in the hit-to-lead development phase.

The first ContraFect project to be Powered by CARB-X was announced in April 2017 for the development of a lysin for the treatment of invasive infections caused by P. aeruginosa.

New antibiotics, rapid diagnostics, vaccines and other products are needed urgently to treat bacteria that are increasingly resistant to existing antibiotics. According to the World Health Organization, an estimated 700,000 people die each year worldwide from bacterial infections. In the United States, an estimated 23,000 people die each year from drug-resistant bacterial infections, according to the CDC. In Europe, the number of deaths each year is estimated at 33,000.

CARB-X’s expanding portfolio

With the latest ContraFect project, CARB-X is now supporting the development of 13 projects that represent new classes of antibiotics. The CARB-X portfolio has 35 innovative projects world-wide and that number is expected to increase significantly this year. Since it was established in 2016, CARB-X has announced awards exceeding $110.8 million, plus additional funds if project milestones are met, to accelerate the development of antibacterial products. These funds are in addition to investments made by the companies themselves. The CARB-X pipeline will continuously evolve, as projects progress and others fail for a variety of reasons. In total since it was established, CARB-X has announced awards for 42 projects.

Partnership to drive antibacterial innovation globally

CARB-X is investing up to $500 million in antibacterial R&D between 2016-2021. The goal is to support projects through the early phases of development through Phase 1, so that they will attract additional private or public support for further clinical development and approval for use in patients. The scope of CARB-X funding is restricted to projects that target drug-resistant bacteria highlighted on the CDC’s 2013 Antibiotic Resistant Threats list, or the Priority Bacterial Pathogens list published by the WHO in 2017 – with a priority on those pathogens deemed Serious or Urgent on the CDC list or Critical or High on the WHO list.

About ContraFect
ContraFect is a biotechnology company focused on discovering and developing therapeutic protein and antibody products for life-threatening, drug-resistant infectious diseases, particularly those treated in hospital settings. An estimated 700,000 deaths worldwide each year are attributed to antimicrobial-resistant infections. We intend to address life threatening infections using our therapeutic product candidates from our lysin and monoclonal antibody platforms to target conserved regions of either bacteria or viruses (regions that are not prone to mutation). Lysins are a new therapeutic class of bacteriophage-derived, recombinantly produced, antimicrobial proteins with a novel mechanism of action associated with the rapid killing of target bacteria, including antibiotic-resistant strains. ContraFect’s lead lysin candidate, exebacase (CF-301) is completing a Phase 2 clinical trial for the treatment of Staphylococcus aureus (Staph aureus) bacteremia, including endocarditis.
