Aims The study objectives were to evaluate the pharmacokinetic and pharmacodynamic properties, as well as safety and tolerability, of single doses of taspoglutide, a human glucagon‐like peptide‐1 (GLP‐1) analogue. Methods In a double‐blind, placebo‐controlled study, 48 patients with Type 2 diabetes [mean age 56 ± 7 years; mean body mass index (BMI) 30.4 ± 3.0 kg/m 2 ] inadequately controlled with metformin (≤ 2 g/day) were enrolled in three sequential cohorts; 12 patients in each cohort were randomized to a single subcutaneous injection of taspoglutide (1, 8 or 30 mg) and four received placebo. Results Plasma concentrations peaked within 24 h after injection and were sustained for ≥ 14 days with all doses. In comparison with placebo, the 8‐ and 30‐mg doses of taspoglutide significantly reduced glycaemic parameters, including 24‐h blood glucose and 5‐h postprandial glucose areas under the curve (AUCs), for up to 14 days with the 30‐mg dose ( P < 0.001). The most common adverse events, primarily gastrointestinal in nature, were dose‐dependent and transient. Conclusions A single dose of taspoglutide significantly improved glycaemic parameters in Type 2 diabetes patients for up to 14 days. The formulation was well tolerated and appears suitable for weekly administration.
