Item Metadata only Pharmacokinetics, pharmacodynamics, safety, and tolerability of a single-dose of NN2211, a long-acting glucagon-like peptide 1 derivative, in healthy male subjects(Amer Diabetes Assoc, 2002) Elbrond, B.; Jakobsen, G.; Larsen, S.; Agerso, H.; Jensen, L.; Rolan, P.; Sturis, J.; Hatorp, V.; Zdravkovic, M.OBJECTIVE—The primary objective of the present study was to investigate the safety, tolerability, and pharmacokinetics of a single dose of NN2211, a long-acting glucagon-like peptide 1 (GLP-1) derivative, in healthy male subjects. The secondary objective was to investigate the pharmacodynamics of NN2211. RESEARCH DESIGN AND METHODS—In a double-blind, randomized dose, escalation, placebo-controlled study, healthy male subjects were enrolled at eight consecutive dose levels (1.25, 2.5, 5.0, 10.0, 12.5, 15.0, 17.5, and 20.0 µg/kg) with eight subjects per dose level at a 3:1 active:placebo randomization. After subcutaneous dosing with NN2211, 48-h pharmacokinetic, and 24-h glucose, insulin and glucagon profiles were assessed. In addition, three subjects at each dose level were randomly assigned (one placebo/two active) to an intravenous glucose tolerance test (IVGTT) 9 h after the dose (corresponding to the time to maximal plasma concentration of NN2211). RESULTS—After subcutaneous administration, the half-life of NN2211 was found to be 11–15 h. Overall, although there were no statistically significant differences compared with placebo in the area under the curve (0–9 h for insulin or glucagon), there was a borderline- significant lowering of glucose levels (P = 0.066). During the IVGTT, there was a statistically significant increase in insulin secretion (P = 0.0002), but there was no significant effect on glucagon levels. Although no significant effect was observed on glucose levels during the IVGTT, there was a dose-dependent increase in the glucose disappearance constant. Whereas no serious adverse events were observed, there was a higher incidence of adverse events after active treatment compared with placebo treatment (notably headache, dizziness, nausea, and vomiting). CONCLUSIONS—This study provides evidence that NN2211 has a pharmacokinetic profile consistent with once-daily dosing in humansItem Metadata only The pharmacokinetics pharmacodynamics safety and tolerability of NN2211 a new long-acting GLP-1 derivative in healthy men(Springer, 2002) Agerso, H.; Jensen, L.; Elbrond, B.; Rolan, P.; Zdravkovic, M.AIMS/HYPOTHESIS: Glucagon-like peptide-1 (GLP-1), a polypeptide hormone secreted by the l-cells in the gastrointestinal tract, has shown promising effects as a new treatment modality for patients with Type II (non-insulin-dependent) diabetes mellitus. However, the pharmacokinetic profile of native GLP-1 with a rapid elimination has limited its therapeutic potential. NN2211 is a fatty acid derivative of GLP-1, which pre-clinically has shown a protracted pharmacokinetic profile, while maintaining its biological activity. This study aimed to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of NN2211 in healthy male subjects following seven days treatment. METHODS: In a double-blind, randomized, dose escalation, placebo controlled study, healthy male subjects were enrolled at five consecutive dose levels of NN2211 (1.25, 5.0, 7.5, 10.0, 12.5 μg/kg). Six subjects were allocated at random at each dose level to active or placebo treatment with a ratio of 2:1. Dosing with NN2211 was performed on day 1, and days 5–11. The 84-h pharmacokinetics and 24-h glucose and insulin profiles were assessed on day 1 and day 11. Results: Following s. c. administration the half-life of NN2211 was found to be 12.6 ± 1.1 h, with a subsequent accumulation index after a daily dose for seven days of 1.4–1.5. There were dose-proportional increases in exposure (AUC and Cmax) with increasing doses. Overall, there were no statistically significant differences from placebo in the 24-h glucose and insulin profiles. In subjects treated with NN2211 rather than placebo, there was a higher incidence of adverse events, most notably dizziness and adverse events related to the gastrointestinal system. There were no serious adverse events but three subjects were nonetheless withdrawn because of dizziness, fever and nausea. There were no clinically relevant changes in vital signs, ECG parameters, physical examination or safety laboratory parameters. A significantly lower diuresis was observed in the actively treated subjects, without a clinically relevant change in packed cell volume. CONCLUSIONS/INTERPRETATION: This study shows NN2211 has a pharmacokinetic profile supporting a daily dose in human beings, but also that subjects treated with NN2211 rather than placebo, had a higher incidence of adverse events, most notably dizziness and adverse events related to the gastrointestinal system.
