Ipsen: Roche Moves Investigational Diabetes Drug, Taspoglutide, into Phase III Clinical Trials
"These data reinforce the role of GLP-1 in type 2 diabetes and Roche and Ipsen believe taspoglutide has the potential to be a best-in-class treatment," said William M. Burns, CEO Pharmaceuticals Division of Roche and Jean-Luc Belingard, Chairman and CEO of the Ipsen Group. "GLP-1 analogues, which stimulate insulin secretion and suppress glucagon secretion, are true innovations in the diabetes field. Roche and Ipsen are pleased to move this potentially best-in-class product into phase III trials and look forward to working together to bring it to market" they said.
The Phase II studies showed that the safety profile of taspoglutide, which originates from Ipsen's research, supports the move into Phase III,(1,2) with the most common adverse event reported being mild-to-moderate nausea. These events were dose-dependent and in most cases, resolved spontaneously while continuing on therapy.
"These data show that taspoglutide is a promising and highly efficacious once-weekly treatment for obese patients with type 2 diabetes mellitus no longer controlled on oral antidiabetic medications," said lead author, Professor Michael Nauck, Head of the Diabeteszentrum Bad Lauterberg, Germany. "Like improved glucose control, drug-induced weight loss is particularly beneficial for this type of patients. We will wait to see the Phase III results with interest".
Roche exercised its licensing option for taspoglutide from Ipsen in 2006 and acquired exclusive worldwide rights to develop and market taspoglutide, except in Japan where these rights are shared with Teijin and in France where Ipsen may elect to retain co-marketing rights.
About the studies
Eight Weeks of Treatment with the Long-Acting, Human GLP-1 Analogue Taspoglutide Improves Glycemic Control and Lowers Body Weight in Subjects with Type 2 Diabetes Mellitus (T2DM) Treated with Metformin: A Double-Blind Placebo-Controlled Phase 2 Study(1)
-- Study evaluated the efficacy, safety and tolerability of taspoglutide in patients with Type 2 diabetes mellitus inadequately controlled with metformin
-- 306 patients were randomized to 8 weeks of treatment with placebo (PLO) or taspoglutide, either 5, 10, or 20 mg weekly (QW), or 10 and 20 mg once every two weeks (Q2W) and followed-up for 4 additional weeks after the last administered dose
-- Significant reductions in HbA1c were seen after 8 weeks of treatment compared to PLO. The percentage of patients who achieved target HbA1c less than or equal to 7% at end-of-study was 59%, 79 %, 81% in the 5 mg, 10 mg, 20 mg weekly arms and 44% and 63% in the 10 and 20 mg every two weeks respectively versus 17% with PLO
-- Body weight decreased progressively and dose-dependently, with significant reductions from baseline in the 10 and 20 mg QW and 20 mg Q2W arms
-- The most common adverse event (AE) was dose-dependent, transient, mild-to-moderate nausea. No episodes of pancreatitis were reported in this study
Safety and Tolerability of High Doses of the Long-Acting, Human GLP-1 Analogue Taspoglutide in Diabetic Subjects Treated with Metformin: A Double-Blind, Placebo-Controlled Phase 2 Study(2)
-- Study evaluated safety and tolerability of escalating doses of taspoglutide in patients with Type 2 diabetes mellitus inadequately controlled with metformin
-- 133 patients were randomized of which 129 patients received either placebo (PLO) or 20 mg taspoglutide weekly for 4 weeks, followed by either maintenance at 20 mg (20/20), or a dose increase to 30 mg (20/30) or 40 mg (20/40) weekly with matched PLO for additional 4 weeks. Patients were then followed up for 4 weeks after the last administered dose
-- Significant improvements in glycemic control were observed in all active arms. At the end of treatment, the percentage of patients reaching HbA1c less than or equal to 7% was 72%, 53% and 70% with 20/20, 20/30 and 20/40 respectively versus 19% with PLO
-- As expected, the most common AE was nausea: transient, mild-to-moderate, appearing early during therapy and resolving spontaneously while continuing on therapy in most cases. No episodes of pancreatitis were reported in this study
About Taspoglutide (R1583)
Taspoglutide was selected from a family of human once-weekly long-acting glucagon-like peptide-1 (GLP-1) analogues with structural modifications which confer intrinsic controlled release properties. Ipsen is the originator of the concept of matrix free sustained release formulation applied to therapeutic peptides and proteins. Taspoglutide is being developed as a novel and innovative treatment for patients with type 2 diabetes mellitus, the fourth leading cause of death in most developed countries. The structure of the molecule is similar to that of the natural human hormone GLP-1, and has the potential for intervals of up to two weeks in between administration without the use of a matrix. Taspoglutide is currently moving into Phase 3 clinical trials.
Diabetes is a disease characterized by excess blood glucose due to a deficiency in insulin availability and/or resistance to its action. Type 2 diabetes accounts for 90% to 95% of all diabetes cases worldwide and occurs almost entirely in adults. Complications from diabetes, such as coronary artery and peripheral vascular disease, stroke, diabetic neuropathy, amputations, renal failure and blindness, are resulting in increasing disability, reduced life expectancy and enormous health cost for virtually every society. According to current estimates by the World Health Organization, the number of people with diabetes is set to more than double in the next 20 years to over 300 million by the year 2025.
