Trial Outcomes & Findings for Extension to Study 200952 to Evaluate the Long-term Safety, Tolerability and Pharmacodynamics of Albiglutide Liquid Drug Product in Type 2 Diabetes Mellitus Subjects (NCT NCT02750930)

NCT ID: NCT02750930

Last Updated: 2019-07-12

Results Overview

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product whether or not it is considered drug related. This would include any side effect, injury, toxicity, sensitivity reaction, abnormal or worsening of a laboratory value, concurrent illness or sudden death. Pre-existing conditions that worsen during a study will be reported as AEs. SAE is any AE that results in death, is life-threatening, requires inpatient hospitalization or extends a current hospital stay, results in an ongoing or significant incapacity or interferes substantially with normal life functions, or causes a congenital anomaly or birth defect, or is associated with liver injury or impaired liver function. Number of participants who reported any AE or SAE during this extension study or who had ongoing AE or SAE from study 200952 have been presented.

Participant Flow

A total of 8 participants with Diabetes Mellitus type II, were enrolled in the study from 3 centres in United States of America. The study was conducted from 07 October 2016 to 21 March 2017. The study was terminated prematurely as a reflection of GlaxoSmithKline business considerations.

The participants who completed study 200952 and who were eligible, were included in this open-label extension study 204682. This was an extension study, hence visit 1 of this study was also a last treatment visit of study 200952 (NCT02683746).

Anti-albiglutide antibodies were planned to be assessed using a validated enzyme-linked immunosorbent assay, which utilized a tiered testing approach. It was to be collected at specified timepoints at Week 0, Week 4, Week 10, Week 26 and Week 34 (follow-up). Confirmed positive samples were to be titrated to obtain the titer of anti-albiglutide antibodies. The number of participants with positive results of anti-albiglutide antibody production was to be reported. However, due to early termination only limited number of key safety data was analyzed. This study 204682 was planned as an extension of the main study, 200952 and was supposed to end well after the main study. However, the 204682 extension study was terminated prior to completion of the main study 200952, which is a double-blind study. To preserve the integrity of the main study 200952, results of anti-albiglutide antibody were not completed after the termination.
