The Effects of Hormones in Growth Hormone-Treated Girls With Turner Syndrome
The Relative Effects of Androgen, Estrogen, and the Combination of Androgen and Estrogen on Growth Rate, GH Binding Protein, IGF-I, and Cognitive Function in Growth Hormone-Treated Girls With Turner Syndrome
Sponsor: Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)
Listed as NCT00001343, this PHASE2 trial focuses on Dwarfism and Turner's Syndrome and remains completed. Sponsored by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), it has been updated 7 times since 1992, reflecting limited change activity. This study adds to the evidence base for this therapeutic area through structured, versioned documentation.
Study Description(click to expand)Turner syndrome is associated with short stature, multiple physical stigmata, and absent pubertal development. We propose to: (1) examine the effects of sex steroids (androgen) on multiple variables (growth rate, GH binding protein, IGF-I, and cognitive function), in the setting of supplemental growth hormone administration and (2) to investigate any synergistic or additive effects of the androgen and estrogen combination on the above variables.
