The World Trade Center (WTC) Health Program supports exploratory and developmental research projects (R21) that address issues related to diagnostic or treatment uncertainty among individuals receiving monitoring and/or treatment under Subtitle C of the James Zadroga 9/11 Health and Compensation Act of 2010, as amended. This R21 Notice of Funding Opportunity (NOFO) is intended to encourage exploratory/developmental research by supporting the early and conceptual stages of project development to assess the feasibility of new areas of investigation with the potential to improve treatment effectiveness and diagnostic practices. These studies may lead to breakthroughs in a particular area or to the development of new interventions, techniques, agents, methodologies, models, or approaches with potential clinical impact. They are expected to break new ground or extend prior discoveries in new directions or applications. Applicants are expected to propose research for which there is likely to be minimal or no preliminary data.
