The National Institute of Diabetes and Digestive and Kidney Disorders (NIDDK) intends to promote a new initiative by publishing a Notice of Funding Opportunity (NOFO) to solicit applications for the TrialNet Clinical Network Hub (HUB). The purpose of this Notice of Funding Opportunity (NOFO) is to continue support for the Type 1 Diabetes TrialNet Clinical Network Hub (HUB), a screening and clinical activities coordination unit for clinical trials focusing on the prevention of and early intervention in type 1 diabetes (T1D). The main objective of the HUB is to increase the efficiency and productivity of the TrialNet network by providing coordination of communications and outreach and developing new tools and approaches to increase screening, recruitment and retention. This NOFO requires a Plan for Enhancing Diverse Perspectives (PEDP), which will be assessed as part of the scientific and technical peer review evaluation. Applications that fail to include a PEDP will be considered incomplete and will be withdrawn. Applicants are strongly encouraged to read the NOFO instructions carefully and view the available PEDP guidance material. This Notice is being provided to allow potential applicants sufficient time to develop meaningful collaborations and responsive projects. The NOFO is expected to be published in Spring 2024 with an expected application due date in Summer 2024. This NOFO will utilize the U01 activity code. Details of the planned NOFO are provided below.
