Researchers at the Andrew G Myers Research Group at the Harvard University Department of Chemistry and Chemical Biology are engineering synthetic antibiotics that directly target bacteria which cause lower respiratory tract and skin and soft tissue infections
(BOSTON: February 13, 2024) – Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) is awarding US$1.2 million to the Andrew G Myers Research Group at the Harvard University Department of Chemistry and Chemical Biology based in Cambridge, Massachusetts, USA, to develop a series of enhanced oral antibiotics that directly target a range of antibiotic-resistant bacteria which cause serious lower respiratory tract and skin and soft tissue infections.
Lower respiratory tract infections are among the world’s most deadly communicable diseases. They are estimated to have killed 2.6 million people globally in 2019, and they cause a substantial mortality, morbidity and economic burden for vulnerable people in low-income countries, where they are the second leading cause of death. Skin and soft tissue infections (SSTIs) are the most common healthcare-associated infection (HAI), accounting for 31% of all HAIs among hospitalized patients. Every year, SSTIs affect more than 500,000 patients and lead to an estimated 8,000 deaths.
“More than 70% of the antibiotics launched since 2010 do not offer an oral option for patients,” said Erin Duffy, PhD, R&D Chief of CARB-X. “Oral antibiotics enable patients to be treated at home, which can reduce healthcare costs and increase access globally, including in low- and middle-income countries where the burden of antimicrobial resistance is highest.”
The CARB-X award supports the development of enhanced lincosamides (a class of antibiotics used to treat certain types of bacterial infections) with targeted performance enhancements over the class exemplar, clindamycin. These molecules inhibit the most prolific and clinically-validated targets for antibiotics, the bacterial ribosome. When the ribosome is blocked, bacterial cell growth is inhibited. The enhanced lincosamides overcome a variety of different mechanisms that bacteria have developed to prevent antibiotics from binding to ribosomes, which has made some commonly used antibiotics ineffective. The Myers Research Group at the Harvard University Department of Chemistry and Chemical Biology, led by Professor Andrew G. Myers, PhD, intends to deliver new frontline treatments for infections with high instances of antibiotic resistance.
“The award from CARB-X will allow us to profile several promising antimicrobial leads in studies to define their potential to advance into preclinical development, or further guide chemical optimization,” stated Andrew Myers, PhD, Amory Houghton Professor of Chemistry at Harvard University. “This advancement in research in antibiotics has the exciting potential to combat drug-resistant bacteria, with promise of major impact on global health.”
The Myers Research Group’s project that is being advanced by CARB-X has received significant funding and advisory support from the Blavatnik Biomedical Accelerator. The Office of Technology Development worked with Professor Myers to protect the research group’s innovations, resulting in a robust patent portfolio for this technology. The Blavatinik Biomedical Accelerator and the Office of Technology Development will continue to support the research group throughout the duration of the agreement with CARB-X.
An estimated 1.27 million people died due to drug-resistant bacterial infections in 2019, a death toll that exceeded HIV/AIDS (864,000) and malaria (643,000) in that same year. CARB-X is building a pipeline of products to prevent, diagnose and treat bacterial infections, including those that have become resistant to antibiotics. CARB-X emphasizes performance characteristics that will allow the broadest use of these products against infections driving the greatest global morbidity and mortality.
CARB-X Supporting Solutions
When CARB-X was founded in 2016, the early-stage antibiotic pipeline was stalled. Since then, CARB-X has supported 96 R&D projects in 13 countries, and CARB-X product developers have made tremendous progress: 18 projects have advanced into or completed clinical trials; 12 remain active in clinical development, including late-stage clinical trials; and two diagnostic products have reached the market. Additionally, at least nine product developers with active R&D projects have already secured advanced development partnerships which can help support their clinical development after leaving the CARB-X portfolio.
Last year, CARB-X launched new funding rounds to support R&D projects and fill critical gaps in the antibacterial pipeline. These include oral therapeutics to replace the workhorse antibiotics that are failing; vaccines for neonatal sepsis, which kills 2.5 million infants annually; and oral therapeutics, vaccines and rapid diagnostics for gonorrhea. Resistant strains of gonorrhea have evaded all but one existing antibiotic. The Harvard University Department of Chemistry and Chemical Biology’s oral therapeutic is the fifth project and second therapeutic to receive a CARB-X grant as part of the 2022-2023 funding call. Additional projects are under review, and new product developers will be announced this year.
CARB-X is funded in part with federal funds from the U.S. Department of Health and Human Services (HHS); Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA) under agreement number 75A50122C00028 and by awards from Wellcome (WT224842), Germany’s Federal Ministry of Education and Research (BMBF), the UK Department of Health and Social Care as part of the Global Antimicrobial Resistance Innovation Fund (GAMRIF), the Public Health Agency of Canada (PHAC), the Bill & Melinda Gates Foundation, and the Novo Nordisk Foundation. The U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) in HHS, provides support in the form of in-kind services through access to a suite of preclinical services for product development.
