Trial Outcomes & Findings for Uridine Adolescent Bipolar Depression Randomized Controlled Trial (NCT NCT01805440)

NCT ID: NCT01805440

Last Updated: 2018-03-12

Results Overview

Magnetic Resonance Spectroscopy is a safe, non-invasive method for measuring brain chemicals thought to be involved in mood disorders, such as GLX (glutamate + glutamine). Previous research indicates that adolescents with bipolar depression have elevated Glx concentrations, compared with controls. The measurement of Glx with 1H-MRS has the potential to identify translational biomarkers of juvenile BD pathophysiology and treatment response.

PRIMARY outcome

Timeframe: 6 weeks

The CDRS-R is a brief rating scale based on a semi-structured interview with the participant (and/or their parent or guardian). The scale can be administered and scored in under 30 minutes. The CDRS-R gives you a single summary score -- with an interpretation of, and clinical recommendations for, six different score ranges. Total possible scores range from 17 to 113, with higher scores indicating more depressive symptoms reported by the participant (and/or their parent or guardian).

SECONDARY outcome

Timeframe: 6 weeks

The Columbia-Suicide Severity Rating Scale (C-SSRS) is used to measure suicidal thoughts and behaviors in Investigational New Drug (IND) studies. The C-SSRS rates an individual's degree of suicidal ideation (SI) on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The scale identifies SI severity and intensity, which may be indicative of an individual's intent to commit suicide. C-SSRS SI severity subscale ranges from 0 (no SI) to 5 (active SI with plan and intent).
