Trial Outcomes & Findings for Binge Eating & Birth Control (NCT NCT04278755)

NCT ID: NCT04278755

Last Updated: 2022-07-26

Results Overview

Binge eating frequency is based on a weekly diary of self-reported binge eating frequency. Participants were asked how many times during the past week they had a binge eating episode. Scores can range from 0 to infinity as frequency is self-reported as the number of binge eating episodes in the previous week. Higher scores indicate more episodes of binge eating. Change is defined as the average change in self-reported binge eating frequency from pre-intervention to intervention.

Timeframe: Pre-intervention (week 1) to intervention endpoint (week 12)

Population: Participants that started the study medication and completed the pre-intervention and intervention endpoints.

Binge eating frequency is based on a weekly diary of self-reported binge eating frequency. Participants were asked how many times during the past week they had a binge eating episode. Scores can range from 0 to infinity as frequency is self-reported as the number of binge eating episodes in the previous week. Higher scores indicate more episodes of binge eating.

Binge eating will be measured using the 8-item binge eating subscale of the Eating Pathology Symptoms Inventory (EPSI), which measures features of binge eating (e.g., consumption of large quantities of food, mindless eating) on a 5-point Likert scale from "never" to "very often." The EPSI scale is designed to assess behavior over the past 28 days. Items are summed for a scale score ranging from 0-32. Higher scores indicate more frequent experiences with binge eating behavior. Change is defined as the average change in the binge eating scale score from pre-intervention to intervention.

PRIMARY outcome

Timeframe: Pre-intervention (week 1) to intervention endpoint (week 12)

Population: Participants who started the study medication and completed the pre-intervention and intervention endpoints. Due to technological error when saving data, one participant's endpoint MRI data was unusable.

Nucleus Accumbens (NAcc) reactivity to reward during the Monetary Incentive Delay (MIDT) task compared pre and post treatment. During MIDT task, participants respond to "win" trials by pressing a button on a button box in the MRI as quickly as possible when they see a target. Reactivity is measured by examining participant's change in blood-oxygen-level dependent (BOLD) (i.e., measurement of oxygen level that is carried to neurons by red blood cells since areas of the brain that are thought to be more "active" or involved in certain tasks require more oxygen) in response to a stimulus of interest (win trials) versus non-stimulus (non-win trials). Percent signal change in BOLD activation between monetary reward versus non-reward is the outcome of interest. Percent signal change is then compared pre- and post-treatment.

Dorsal striatum reactivity (defined as caudate signal intensity and putamen signal intensity) to reward during the Monetary Incentive Delay (MIDT) task compared pre and post treatment. During MIDT task, participants respond to "win" trials by pressing a button on a button box in the MRI as quickly as possible when they see a target.

Population: Participants who started the study medication and completed the pre-intervention and intervention endpoints. Due to technological error when saving data, one participant's endpoint MRI data was unusable.

Prefrontal cortex reactivity to reward during the Monetary Incentive Delay (MIDT) task compared pre and post treatment. During MIDT task, participants respond to "win" trials by pressing a button on a button box in the MRI as quickly as possible when they see a target. Reactivity is measured by examining participant's change in blood-oxygen-level dependent (BOLD) (i.e., measurement of oxygen level that is carried to neurons by red blood cells since areas of the brain that are thought to be more "active" or involved in certain tasks require more oxygen) in response to a stimulus of interest (win trials) versus non-stimulus (non-win trials).

Population: Participants that started the study medication and completed the pre-intervention and intervention endpoints.

The Monetary Choice Questionnaire will be used to measure delay discounting. Participants will be asked to make a series of hypothetical choices between small, sooner (impulsive) vs. larger, later (self controlled) hypothetical monetary outcomes. k is a hyperbolic function with larger k values indicating more valuation of a larger delayed reward and smaller values indicating preference for more immediate, smaller rewards (more impulsivity). k can range from 0 to .25 with scores of .25 indicating complete valuation of the immediate reward and 0 indicating complete valuation of the larger, delayed reward. Change is defined as the average change in k from pre-intervention to intervention.

Sensitivity to Punishment/Sensitivity to Reward Questionnaire will be used to measure reward sensitivity. The reward sensitivity subscale will be used, which is rated on a true/false scale with scores ranging 0-24. Higher scores indicate more sensitivity to reward. Change is defined as the average change in reward sensitivity from pre-intervention to intervention.
