Multiple Dose Escalation Trial Of PF-04603629 Given To Subjects With Type 2 Diabetes Mellitus
A Phase 1, Randomized, Placebo-Controlled, Sequential Parallel Group, Multiple Dose Escalation Trial To Evaluate The Safety, Tolerability, Pharmacokinetics, And Pharmacodynamics Of 4, Once-Weekly Subcutaneous Doses Of PF-04603629 To Subjects With Type 2 Diabetes Mellitus
PF-04603629 is being investigated for the treatment of Type 2 diabetes mellitus (T2DM). Specifically, PF-04603629 is a protein that is a combination of exendin-4 (a glucagon-like peptide-1 (GLP-1) mimetic currently marketed as Byetta®) fused to human transferrin (a naturally occuring protein) in order to increase the concentration of exendin-4 in the blood. The purpose of this study is to characterize the safety, tolerability, pharmacokinetics, and pharmacodynamics of PF-04603629 following multiple escalating subcutaneous doses in adult subjects with T2DM.
B0571002 was terminated August 19 2008 due to the decision to discontinue development of PF-04603629 after observing (in both B0571001 and B0571002) a trend for a reversible increase in heart rate within the normal range, which occurred at efficacious doses. Thus, the compound was primarily terminated due to safety concerns, although there was no immediate safety risk to any subject in the study.
