Recruitment
|
|||||||||||||||||||||||||
Recruitment details |
This was a multicenter study conducted at 29 sites in Europe (Spain 10, United Kingdom (UK) 9, Germany 4, France 3 and Italy 3). A total of 67 participants with New-onset type 1 diabetes mellitus (NOT1DM) were randomized. | ||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||
Screening details |
Study was terminated early as part of the decision to withdraw albiglutide for commercial reasons. Study stopped after 67 participants were randomized instead of 68 as per protocol. Impact of early termination was minimal and did not affect the interpretation of results. | ||||||||||||||||||||||||

End point description |
Participants (parts) had a balanced diet consistent with dietitian’s advice and made no major changes in exercise regimens. Evening before the MMTT, participants had a full meal then fasted from 9 post meridiem (pm) until MMTT was completed. Water, black coffee or tea without sugar or artificial sweeteners was allowed. Plasma glucose was measured prior to the finger-stick test and MMTT was performed only if in range > 3.9 millimoles per liter (mmol/L) [70 mg/deciliter (dL)] and <= 11.1 mmol/L (200 mg/dL). Baseline was defined as the last non-missing value with assessment date on or before the 1st day of study medication. Change from Baseline was calculated by subtracting Baseline value from Week 52 value. Intent-to-treat (ITT) Population comprised of all randomly assigned participants who received at least 1 dose of study medication with at least 1 post-Baseline assessment of the primary endpoint.

Time spent with a plasma glucose <=3.9 millimoles per liter (mmol/L), between >3.9 and 10.0 mmol/L, and >10.0 mmol/L, respectively as performed by 72-hour CGM at Baseline, Week 28 and Week 52 was reported.

Population estimates of Pharmacokinetic (PK) parameters: apparent clearance [CL/F] [34] | ||||||||||
End point description |
PK of Albiglutide was evaluated in participants using CL/F using PK samples collected on Weeks 4, 6, 8, 16. CL/F was evaluated by population PK methods and mean and standard error from the final model has been tabulated. Estimates have been presented from the final model centered to mean bodyweights of 67 kilograms, and electronic glomerular filtration rate (eGFR) of 123 milliliters per minute. PK population comprised of participants in Safety Population for whom a PK sample was obtained and analyzed. Only participants who received albiglutide were included in PK Population.
