The National Institute on Aging (NIA) intends to publish a Funding Opportunity Announcement (FOA) to solicit applications to conduct a clinical trial(s) on effects of vitamin D supplementation on falls and gait speed in older community dwelling individuals.

Applicants are strongly encouraged to consider advanced, cost-efficient designs that include a dose-ranging phase followed by an efficacy phase for select doses. This Notice is being provided to allow potential applicants sufficient time to develop meaningful collaborations and responsive projects. 

The FOA is expected to be published in May 2013 with an anticipated receipt date in August 2013.

This FOA will utilize the U01 activity code.  Details of the planned Funding Opportunity Announcement (FOA) are provided below.
