The National Institutes of Health (NIH) is inviting applications for the NIDCD Clinical Research Center Grant (P50 Clinical Trial Optional), aimed at advancing research on human communication disorders. This grant supports interdisciplinary studies related to hearing, balance, smell, taste, voice, speech, and language, with an emphasis on low-risk clinical trials that do not require FDA oversight, although such trials are optional. The initiative highlights the critical need for research that enhances the diagnosis, treatment, and prevention of communication disorders, significantly impacting public health. Eligible applicants include various institutions, particularly minority-serving organizations, with a funding limit of $1.5 million per year for a maximum project duration of five years. Interested parties should submit their applications by October 9, 2024, and can direct inquiries to the NIH OER Webmaster at OERWebmaster03@od.nih.gov.
