A Study Comparing the Effect of Albiglutide With Exenatide on Regional Brain Activity Related to Nausea in Healthy Subjects

2016-06-16 18:23:21 | BioPortfolio

Summary

The drug effects will be studied after a single dose of 50 milligram (mg) albiglutide and a single dose of 10 microgram exenatide, to gain insight into the central mechanisms of nausea associated with Glucagon-like peptide-1 receptor (GLP-1R) agonists. This study will explore the potential differences at the expected time of maximum concentration (Cmax) between a long-acting (albiglutide) and short-acting (exenatide) GLP-1R agonist in brain activation of healthy volunteers assessed by magnetic resonance imaging (MRI). This is a phase IV, 2-part, 2-period crossover (session), single dose, randomized, single blind (blinded to both the subject and the imaging evaluators analysing the MRI data), placebo- and active-controlled study in adult healthy volunteers who are susceptible to motion sickness. Part A and Part B are the same in design, both consisting of a screening stage, a dosing/assessment stage, and a follow-up visit. Data from Part A will inform progression, methods, and analysis plan for Part B. Each sequence includes three scanning visits: albiglutide plus scan, exenatide plus scan and an off-therapy -natural history scan with a 6-9 week washout period between the dosing scans. A total of 24 to 28 subjects will be randomized in the study (Part A and Part B). The cross over design is divided into 2 sessions and schedule is as follow, on Day 1 (either Session 1 (S1) or Session 2 (S2) per, if randomized) subject will under go an off-therapy MRI scan, on Day 5 subject will receive a single dose of 50 mg albiglutide or albiglutide placebo, and Day 8 subject will receive a single dose of 10 microgram exenatide or saline placebo followed by a post-dose MRI scan. At each session subject will receive only one active drug (albiglutide or exenatide).

Medical and Biotech [MESH] Definitions

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

An exchange of DNA between matching or similar sequences.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

Repair of DNA DAMAGE by exchange of DNA between matching sequences, usually between the allelic DNA (ALLELES) of sister chromatids.

A health care system which combines physicians, hospitals, and other medical services with a health plan to provide the complete spectrum of medical care for its customers. In a fully integrated system, the three key elements - physicians, hospital, and health plan membership - are in balance in terms of matching medical resources with the needs of purchasers and patients. (Coddington et al., Integrated Health Care: Reorganizing the Physician, Hospital and Health Plan Relationship, 1994, p7)
