Diartis Pharmaceuticals, Inc. is presenting positive data from its completed Phase 1 multicenter clinical trial of VRS-859 (exenatide-XTEN) at the European Association for the Study of Diabetes (EASD) 48th Annual Meeting which began on October 1 in Berlin-Charlottenburg. VRS-859, a long-acting glucagon-like peptide-1 (GLP-1) analog, is being developed as a once monthly treatment for patients with type 2 diabetes mellitus (T2DM). The Diartis poster — “Safety, pharmacokinetics, and pharmacodynamics of a single subcutaneous dose of VRS-859 in patients with type 2 diabetes” — will be discussed by Jeffrey L. Cleland, Ph.D., Diartis Chief Executive Officer on Wednesday, October 3.
The Phase 1 multicenter, blinded, placebo-controlled, single-ascending dose study was designed to evaluate the safety and tolerability of VRS-859 as well as the ability to maintain glycemic control for one month in T2DM patients after a single dose.
Dr. Cleland stated, “We are very pleased with the robust results seen in this initial Phase 1 study as the current data suggests repeated dosing of 200 mg VRS-859 per month will be well tolerated. Most notable were the statistically significant reductions in HbA1c levels at 30 days after only a single 200 mg dose of VRS-859, which is predicted to have a reduction in HbA1c of 1.6 to 2.2% at 6 months.”
The Phase 1 results in T2DM patients demonstrate that all doses administered (up to 200 mg) were well tolerated and no unexpected adverse events were noted. Furthermore, the PK of VRS-859 in these patients was dose linear and comparable to the profile predicted from preclinical studies, validating the half-life extension capability of the XTEN technology and supporting a once monthly dosing regimen for VRS-859. These results support the company’s plan to conduct a 6-month repeat dose study to determine a safe and efficacious subcutaneous dose of VRS-859 in patients with T2DM.
About VRS-859The compound has been designed to provide improved therapeutic outcomes for T2DM patients including robust and sustained improvements in HbA1c, improved tolerability, prolonged half-life (up to monthly dosing), as well as enhanced administration of a liquid formulation via a fine-gauge needle. It is hoped that upon successful development, VRS-859 may allow T2DM patients to safely manage their glucose with a therapy that is superior to current treatments for diabetes.
