Condition(s) targeted: Prematurity

Intervention: Amino acids (Drug)

Phase: N/A

Status: Active, not recruiting

Sponsored by: Women and Infants Hospital of Rhode Island

Official(s) and/or principal investigator(s):
Joseph M Bliss, MD, PhD, Principal Investigator, Affiliation: Women and Infants Hospital of Rhode Island


The purpose of this study is to determine whether providing increased protein to premature infants in the first week of life allows for better growth during the hospital stay and improved developmental outcomes by age 2.
