Funding agreement fuels development of platform targeting universal structure within biofilms to eliminate bacterial defenses and sensitize to immune or antibiotic intervention

COLUMBUS, Ohio – November 18, 2020 Clarametyx Biosciences Inc. (“Clarametyx”), a preclinical stage biotechnology company developing targeted, immune-enabling biologic therapies to counter persistent infections associated with biofilms, today announced that CARB-X (Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator), a global non-profit partnership dedicated to accelerating antibacterial research and development, has awarded the company up to $14.2 million in funding to advance its novel technology platform through the completion of a Phase 1 clinical study. The award is broken down into a base period totaling $2.4M, with three additional milestone-based options, subject to available funds.

Clarametyx is focused on addressing the challenge of biofilm-associated infections. These infections are often resistant to immune response or standard antibiotic regimens due to an extracellular matrix in the biofilm that protects the bacteria, contributing to persistent, harmful inflammatory responses, as well as extended duration and severity of disease. The Clarametyx platform is designed to precisely remove a universal, pathogen-agnostic target within this matrix, rapidly and effectively collapsing the protective shield and sensitizing bacteria to immune and antibiotic attack.

“Bacterial biofilms are a serious global health concern due to their ability to resist both antibiotics and the host’s immune system,” said Erin Duffy, R&D Chief of CARB-X, a non-profit global partnership led by Boston University and dedicated to funding and supporting the development of innovative products to address antibiotic-resistant bacterial infections. “We urgently need new therapeutics to address life-threatening bacterial infections. Clarametyx is developing an exciting new approach that could be effective on a broad range of serious drug-resistant pathogens and also numerous types of infections.”

The platform has the potential to generate a robust pipeline of therapeutics and vaccines that both enhance the activity of the body’s innate immune system and sensitize a wide range of Gram-negative and Gram-positive bacterial pathogens to the action of first-line and other antibiotics. Its lead candidate, CMTX-101, is an immune-enabling antibody therapy with broad-spectrum activity for the treatment of moderate-to-severe pneumonia through co-administration with standard antibiotic regimens to improve patient response to therapy. Moderate-to-severe pneumonia causes more than 500,000 hospitalizations annually in the U.S., with high fatality rates. It contributes significant costs to the U.S. healthcare system through increased length of hospital stay, greater use of antibiotic interventions, need for ventilation and higher ICU resource utilization.

“The CARB-X funding award recognizes the clinical potential of this important technology. With an entirely new approach to persistent bacterial infections, our technology could represent a disruptive innovation that is very well aligned to the CARB-X goals to combat drug resistance,” said Charles McOsker, Ph.D., co-founder and Chief Scientific Officer of Clarametyx. “The funding and technical expertise offered by CARB-X will fuel momentum in our preclinical development to pursue this powerful new solution for life-threatening infections that contribute considerable burden to the global community.”
