Roche's weekly taspoglutide meets primary end-point in key Phase III study

Taspoglutide demonstrates superiority in HbA1c change versus placebo as add-on to metformin and pioglitazone

Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that its Phase III study T-emerge 3 met its primary endpoint of change in HbA1c. T-emerge 3 is a study of once weekly taspoglutide versus placebo, as add-on to metformin and pioglitazone.

The results of T-emerge 3 showed that taspoglutide demonstrated superiority in HbA1c change versus placebo following 24 weeks of treatment. The study analysis included 326 patients, randomized into three arms (taspoglutide 10 mg once weekly, taspoglutide 20 mg once weekly and placebo).

In this study taspoglutide was generally well tolerated and the most frequently reported adverse events among taspoglutide treated patients were nausea and vomiting.  In addition to the already released T-emerge 1, T-emerge 2,  T-emerge 4, T-emerge 5 and T-emerge 7 studies, data from T-emerge 3 will be submitted for presentation at upcoming international scientific meetings. A further two T-emerge Phase III trials exploring taspoglutide in patients with diabetes are ongoing.

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 has elected to retain co-marketing rights.

About T-emerge 3

T-emerge 3 is a combination therapy (add on to metformin and pioglitazone), double blind, placebo controlled, 24 week core study, to demonstrate superiority versus placebo, involving 326 patients equally randomised into three arms (taspoglutide at doses of 10 mg and 20 mg once weekly, and placebo). All patients continue into the 28-week long-term extension on taspoglutide.

About the T-emerge Programme

The T-emerge Phase III clinical trial programme is designed as multicenter, multi-country, randomized, controlled (active or placebo), double-blind and open studies. Over 6,000 patients have been enrolled in the eight studies that comprise the T-emerge programme. Studies include two parallel taspoglutide arms including 10 mg once weekly and 10 mg once weekly titrated up to 20 mg once weekly after four weeks. Four of the eight studies have active comparators, including exenatide, sitagliptin, insulin glargine and pioglitazone.

About Taspoglutide

Taspoglutide is the first once-weekly human glucagon-like peptide-1 (GLP-1) analogue being developed to address the important unmet needs of patients with type 2 diabetes. Taspoglutide is similar to the naturally occurring human hormone GLP-1 which plays a key role in blood glucose modulation while slowing down food absorption and suppressing appetite resulting in glycemic control, weight loss and no incremental risk of hypoglycemia. Taspoglutide is currently in Phase III clinical trials.

About Diabetes

Type 2 diabetes is a global epidemic growing at an exponential rate.  Currently type 2 diabetes affects more than 180 million adults worldwide and the number is expected to escalate to over 360 million by the year 2030. Type 2 diabetes accounts for 90% to 95% of all diabetes cases and is causally linked to obesity; as many as 90% of type 2 diabetes patients worldwide are overweight or obese. Weight management is thus often an important clinical goal.

Even with available therapies, managing type 2 diabetes remains a challenge due to the multi-faceted nature of the disease, complex treatment regimens and the constant demand on life style modification. Many patients struggle with therapy related side effects such as weight gain and hypoglycaemia as a trade off for glucose control. Approximately two-thirds of patients fail to achieve an HbA1c < 7%, and nearly 90% of patients fail to reach the combined treatment goals of glucose control, blood pressure and lipids.

Uncontrolled type 2 diabetes can lead to severe complications such as cardiovascular diseases, stroke, blindness, amputations, and kidney failure, resulting in significant healthcare burdens to society. Therefore, new therapeutic advances in type 2 diabetes are targeted at achieving the multiple clinical goals of patients with type 2 diabetes while enhancing patient compliance and supporting the necessary lifestyle changes to improve long-term outcomes.
