Trial Outcomes & Findings for CoQ10 in Geriatric Bipolar Depression (NCT NCT00720369)

NCT ID: NCT00720369

Last Updated: 2014-01-13

Results Overview

The rate constant for creatine kinase is a measurement of the reaction rate ADP+PCr \<---\> ATP + Cr, which is catalyzed by the enzyme creatine kinase. The rate constant shows the direction and magnitude of the reaction at equilibrium. A higher rate constant indicates a higher rate constant of the CK enzyme, meaning, more efficient/rapid conversion of PCr to ATP through the creatine kinase enzymatic reaction in tissues with high and fluctuating energy demands such as brain and muscle tissue. As the value is a reaction rate, there are no associated units.

Participant Flow

Please note that subjects who sign the informed consent form are considered "enrolled." Only subjects who met eligibility following screening are included in analyses and thus included in the "participant flow." Of the 42 enrolled, 19 started the study and 18 completed.

Measure
CoQ10
Subjects were given open-label, adjunct treatment with CoQ10 with oral dosing between 400-1200mg per day. Dosing was started at 400mg and titrated up to 1200mg as tolerated. This value does not match the value of subjects enrolled because only subjects who were not screen failures are included in this group.
Healthy Controls
Healthy age matched control subjects do not receive treatment. Controls undergo testing and MRIs to serve as comparison group. This value does not match the value of subjects enrolled because only subjects who were not screen failures are included in this group.

SECONDARY outcome

Timeframe: 8 week trial

Population: Clinical improvement following treatment with CoQ10 supplement was only tested in the Bipolar subject cohort, not in healthy controls, therefore outcome data only apply to the bipolar group.

The Montgomery Asberg Depression Rating Scale (MADRS) is a 10 question questionnaire which assesses symptom severity of depression. The score is on a 0-60 scale with higher numbers indicating more severe depressive symptoms. The score is represented as a number of points. Clinical improvement following treatment with CoQ10 supplement was only tested in the Bipolar subject cohort, not in healthy controls, therefore outcome data only apply to the bipolar group.
