A Study of LY2405319 in Participants With Type 2 Diabetes

Eli Lilly and Company47 enrolled

Overview

The main purpose of this study was to evaluate the safety and tolerability of LY2405319. It was given as a daily injection under the skin to participants with type 2 diabetes mellitus (T2DM) for 28 days. This study determined how long the drug stays in the body and how it affects blood sugar levels. After screening, the study lasted about 2 months for each participant. Participants continued their prestudy regimen of diet and exercise alone or in combination with metformin.

Change From Baseline to Day 28 in Eating Inventory for Cognitive Restraint of Eating, Disinhibition, and Hunger

Change from baseline to Day 28 in Eating Inventory (EI) subscales are presented. The EI is a 51-item inventory that measures dietary restraint (the cognitive intention to restrict energy intake; scores range from 0 to 21), disinhibition (the tendency to episodically overeat, often in response to external cues; scores range from 0 to 16), and perceived hunger (scores range from 0 to 14). A low score indicates a low exhibition of behavior and a high score indicates a high exhibition of behavior. The measurement for each variable obtained on Day -2 served as the baseline value. LS means were calculated using an analysis of covariance model with treatment, day, and treatment times day as fixed effects, and baseline as covariate.

Time frame: Baseline, Day 28

Change From Baseline to Day 28 in the Food Preference Questionnaire (FPQ) Score

The table below represents the change from baseline in FPQ total score. The FPQ was administered to assess overall preference for foods of different macronutrient contents utilizing a macronutrient self-selection paradigm. Participants rated their preference on a range from 1 to 9 with 1 (dislike extremely) to 9 (like extremely) for a battery of 72 commonly consumed foods with fat content varying significantly in sugar, complex carbohydrates, and protein. The total score was calculated by averaging preference scores of 72 items. A low mean score of 1 to 9 scale indicate a low preference for the foods listed and a high mean score indicate a high preference for the foods listed. The FPQ measurement on Day -2 served as the baseline value. LS means were calculated using an analysis of covariance model with treatment, day, and treatment times day as fixed effects, and baseline as covariate.

Time frame: Baseline, Day 28

Change From Baseline to Day 28 in The Patient Health Questionnaire (PHQ-9) Score

Change from baseline to Day 28 in the PHQ-9 total score is presented. Participants were asked to score the severity of depressive symptoms over the last 2 weeks. Items were scored 0 (not at all), 1 (several days), 2 (half of the days), or 3 (nearly every day). The total PHQ-9 score is the sum of the score for each item and range from 0 to 27. A score of 0 means low depression severity and a score of 27 means high depression severity. Depression severity will be given a quality rating based on the total PHQ-9 score, as follows: None (0-4); Mild (5-9); Moderate (10-14); Moderately severe (15-19); and Severe (20-27). The PHQ-9 measurement obtained on Day -2 served as the baseline value. LS means were calculated using an analysis of covariance model with treatment, day, and treatment times day as fixed effects, and baseline as covariate.
