CARB-X is funding Polyphor to develop a new antibiotic to treat multidrug-resistant Enterobacteriaceae Gram-negative bacterial infections

This is Polyphor’s second innovative antibiotic program to be funded by CARB-X

(BOSTON) – CARB-X announced today it is awarding up to US$2.62 million to Polyphor AG (SIX:POLN), headquartered in Allschwil, Switzerland, to develop a new antibiotic to treat serious Enterobacteriaceae Gram-negative bacterial infections, including those caused by life-threatening carbapenem-resistant Enterobacteriaceae (CRE).  Polyphor will be eligible for an additional $15.82 million in funding from CARB-X if project milestones are met, subject to available funds, for a total of $18.44 million.

This is the second antibiotic program under development by Polyphor to win funding and support from CARB-X, a global non-profit partnership led by Boston University dedicated to accelerate the development of new therapeutics, preventatives and diagnostics to address drug-resistant bacteria. The Polyphor program, a novel thanatin-derivative belonging to the new Outer Membrane Protein Targeting Antibiotic (OMPTA) class of antibiotics, aims to treat life-threatening infections caused by difficult-to-treat bacteria identified by the World Health Organization (WHO) and the US Centers for Disease Prevention and Control (CDC) as an urgent and top-priority health threat.

“Serious infections are a global health threat, due in part to the emergence of drug-resistant bacteria for which we do not have therapies,” said Erin Duffy, R&D Chief of CARB-X. “Polyphor’s project enriches the pool of novel approaches to deliver a therapeutic that can treat infections caused by multidrug-resistant Gram-negative pathogens, for which only one new class since 1962 has been approved for use in patients. It is in the early stages of development, and if successful and approved, it could potentially change the way these life-threatening infections are treated and save lives.”

Enterobacteriaceae are a large family of different types of bacteria that commonly cause infections, including urinary tract infections and pneumonia, in healthcare settings. Examples include Escherichia coli (E. coli), Klebsiella pneumoniae and others resistant to nearly all antibiotics.

The novel thanatin-derivative antibiotics discovered by Polyphor and the University of Zurich aim to break down the outer membrane of the bacteria, which serves as protective armor against the effects of antibiotics.  Specifically, the antibiotic works on a novel target, an essential transport mechanism used by Gram-negative bacteria called the lipopolysaccharide (LPS) transport protein A (LptA). This class of antibiotics shows potent and specific antimicrobial activity against Enterobacteriaceae, including extremely drug-resistant strains.

“CARB-X fosters the best science and most promising early development R&D projects in the world. This award provides further support to our research efforts in progressing a new class of antibiotics to combat antimicrobial resistance, one of the greatest global challenges for healthcare,” said Gokhan Batur, Chief Executive Officer of Polyphor. “This second award is a strong validation of our innovative antibiotic platform and an important milestone in the implementation of our renewed strategy in this field presented earlier this year, and we would like to thank CARB-X for their ongoing trust and support.”

New approaches urgently needed to address drug-resistant bacteria

The World Health Organization (WHO) estimates that 700,000 people die each year from drug-resistant infections, including 35,000 in the US and 33,000 in Europe. CARB-X funds only projects that target drug-resistant bacteria highlighted on the CDC’s Antibiotic Resistant Threats list, or the Priority Bacterial Pathogens list published by the WHO, with a priority on those pathogens deemed Serious or Urgent on the CDC list or Critical or High on the WHO list.

CARB-X currently funds and supports 44 active projects focused exclusively on drug-resistant bacteria. CARB-X is investing up to $480 million in non-dilutive funding between 2016-2022 to support the early development of new therapeutics, preventatives and rapid diagnostics. 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 regulatory approval for use in patients.

Since its launch in 2016, CARB-X has announced 70 awards worth $252.7 million, with the potential of additional funds if project milestones are met. 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.
