Trial Outcomes & Findings for A Study Evaluating the Effect of Albiglutide on Gallbladder Emptying in Healthy Subjects (NCT NCT02496221)

NCT ID: NCT02496221

Last Updated: 2018-04-05

Results Overview

Gallbladder ultrasonography was done at Day 1 (-15, -10, and -5 minutes \[min\] relative to start of albiglutide/placebo injection) and Day 4 (\[prior to CCK infusion\] -15, -10, -5 min, followed by \[during CCK infusion\] every 5 min between 0 and 50 min, then \[after CCK infusion\] at 60, 70, and 80 min, relative to the start of CCK infusion). Baseline gallbladder volume is the average of the 3 gallbladder volume measurements prior to CCK infusion on Day 4, for each treatment period. Adjusted mean and its standard error are presented.

PRIMARY outcome

Timeframe: Day 4 in each treatment period

Population: Evaluable Subjects: Participants in the 'All Subjects' population who had gallbladder ultrasonography assessment pre-treatment and post-Baseline (during CCK infusion) for both periods. 'All Subjects' population comprised participants who received at least one dose of Investigational product.

Gallbladder ejection fraction (EF) is defined as the reduction in gallbladder volume at any time point from Baseline divided by baseline gallbladder volume and multiplied by 100. Baseline gallbladder volume is the average of the 3 gallbladder volume measurements prior to CCK infusion on Day 4, for each treatment period. Gallbladder ultrasonography was done at Day 1 (-15, -10, and -5 minutes \[min\] relative to start of albiglutide/placebo injection) and Day 4 (\[prior to CCK infusion\] -15, -10, -5 min, followed by \[during CCK infusion\] every 5 min between 0 and 50 min, then \[after CCK infusion\] at 60, 70, and 80 min, relative to the start of CCK infusion). Adjusted mean and its standard error have been presented.

Population: All Subjects

The following parameters were measured through blood sampling. Hematology: Hematocrit, Hemoglobin, Lymphocytes, Neutrophil Count, Platelet Count, While Blood Cell Count (WBC); Clinical Chemistry: Albumin, Calcium, Creatinine, Glucose, Magnesium, Phosphorus, Potassium, Sodium, Total carbon dioxide; Liver Function Tests: Alanine transaminase (ALT), Aspartate transaminase, Alkaline Phosphatase, Total Bilirubin, Total Bilirubin + ALT. Values were considered to be of potential clinical importance if they had a 'low' or 'high' flag with respect to a pre-defined clinical concern range. Only participants starting each period (represented by n=X) with a particular treatment were analyzed. The follow-up time point is not restricted to a treatment or treatment period.

SECONDARY outcome

Timeframe: Baseline (Day -1) and Day 4 in each treatment period, and at Follow-up (at approximately Week 12)

Population: All Subjects

Single 12-lead ECG was obtained in a semi-supine position after 5 minutes of rest at each indicated time point using an ECG machine that automatically calculated the heart rate and measured the PR, QRS, QT, and QT corrected by Fridericia's formula (QTcF) intervals. Change from Baseline was calculated as value at indicated time point minus Baseline value.

An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect, may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition, associated with liver injury and impaired liver function defined as alanine aminotransferase \>=3 x upper limit of normal (ULN), and total bilirubin \>=2 x ULN or international normalised ratio \>1.5. AEs were classified as potentially drug-related, based on the investigator's judgement. Refer to the general AE/SAE module for a list of AEs and SAEs.

Timeframe: Day -1 and Follow-up (assessed up to a total of approximately 12 weeks)

Population: All Subjects

Urine dipstick test was carried out on Day -1 and at Follow-up. Urinalysis parameters assessed were glucose, ketones, nitrite and protein. Dipstick results were categorized as Normal (glucose), Negative or Trace (ketones), and Negative (nitrite and protein). Only participants available at the indicated time points (as represented by n=X, X, X in the category titles) were analyzed. The resultant fields with no available data have been represented by 'NA'.
