Grant Opportunity Analysis

The National Institutes of Health (NIH) is offering a funding opportunity titled "Expanding the Target Landscape by Drugging the Undruggable," aimed at supporting exploratory projects that target currently undruggable protein classes associated with intractable human diseases. Applicants are required to identify a relevant undruggable target class and propose innovative preclinical methods or agents to address treatment gaps, with a focus on developing strategies that cannot be tackled by existing therapeutic approaches. This initiative is crucial for advancing translational science and improving public health outcomes by fostering the development of novel treatments for conditions that currently lack effective therapies. Up to $275,000 is available for projects over a two-year period, with applications due by February 17, 2028. For further inquiries, interested parties can contact NIH Grants Information at grantsinfo@nih.gov.

AI Summary
The National Institutes of Health (NIH), through this Notice of Funding Opportunity (NOFO), invites applications for the "Expanding the Target Landscape by Drugging the Undruggable" program, aimed at facilitating exploratory projects targeting currently undruggable protein classes in intractable human diseases. This funding opportunity, under the R21 Exploratory/Developmental Research Grant, encourages innovative strategies to modulate undruggable targets through the development of techniques or agents that selectively engage these targets. Grant applications must clearly identify a relevant undruggable target class and propose preclinical methods to address the gap in treatment options. Up to $275,000 is available for projects over two years, but clinical trials are not allowed. Eligibility extends to various organizations—including higher education institutions, nonprofits, and local governments—with an emphasis on early-stage investigators. Key dates for submission and review processes are outlined, with applications due by 5 PM local time. This initiative aligns with NIH’s broader mission to accelerate translational science and improve public health outcomes by developing novel treatments for currently untreatable conditions.
