The Department of Health and Human Services, through the Biomedical Advanced Research and Development Authority (BARDA), is issuing a Sources Sought Notice to gather information on antibiotics in development for the treatment of hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) and bloodstream infections (BSI) caused by drug-resistant bacteria. This initiative aims to enhance understanding of the antibiotic development landscape and prepare for future procurement to strengthen U.S. emergency response capabilities against CBRN threats and antibiotic resistance. BARDA is particularly interested in details regarding antibiotic candidates, including their clinical indications, development status, manufacturing plans, and commercialization strategies, with submissions due by November 29, 2025. Interested parties should contact Erin Greninger at erin.greninger@hhs.gov or Audrey Glover at audrey.glover@hhs.gov for further information.
