Phase II clinical trials
Rosenstock et al investigated the safety, efficacy, and
tolerability of escalating doses of albiglutide in patients
with uncontrolled type 2 diabetes mellitus (baseline HbA1C
7.9%−8.2%, average duration of type 2 diabetes mellitus
3.9−6.4 years, see Table 1). Exenatide was included as an
open-label clinical reference. There was a consistent trend
of weight reduction observed across all doses of albiglutide
(ranging from −1.1 kg to −1.7 kg) but was less than in
patients who received exenatide (−2.4 kg). The most frequently
reported adverse effects were nausea (12%−54%),
vomiting (8.6%−41%), diarrhea (5.7%−22%), and headache
(11.4%−23.5%). Gastrointestinal adverse effects were largely
dose-dependent but declined over the course of the study.
Injection site reactions were more common with albiglutide
(28.6%) than with placebo (2.9%) and exenatide (2.9%),
but were mainly mild and unrelated to dose or frequency
of administration. No serious episodes of hypoglycemia
occurred. Anti-albiglutide antibodies were detected in eight
patients; however, three of these patients had positive titers
at baseline, suggesting that immunogenicity may be overestimated.
Overall, albiglutide improved glucose control in a
dose-dependent manner, with a higher frequency of gastrointestinal
adverse effects in the monthly dosing groups.16
