Applicants who have not yet applied will be first asked to register in the CARB-X Portal. To register and to submit an Expression of Interest, click on the button below.
For technical assistance logging into the CARB-X Portal, please email carbxptl@bu.edu.
Target Product Profiles and minimal entry criteria for each theme can be found here. We highly encourage you to read our Frequently Asked Questions. View the slides from the 2026 funding round webinars here.
Expressions of Interest (EOI) for both themes may be submitted from 08 April 2026 at 10:00 ET to 22 April 2026 at 23:59 ET.
In the EOI, you will be asked to answer a series of questions about your proposed project and will be given the opportunity to share pertinent, non-confidential details, in free text. Your application will be judged on the merits of its scientific content; describe your science with as much data as possible. Please do provide sufficient data to allow a knowledgeable scientist to get a reasonable sense of the therapeutic/preventative/diagnostic. Do not provide other manuscripts, references, citations or similar. Note that the form can only accept text; you may not enter tables or graphics. Do not include foundational information regarding the significance of antibiotic resistance; this is not necessary, as the reviewers understand this.
