Isis Pharmaceuticals Reports Data From Phase 2 Study of ISIS-PTP1B Rx in Patients With Type 2 Diabetes
"Despite currently available therapies, many patients with type 2 diabetes are still unable to control their blood glucose levels and eventually require the use of insulin therapy. The only class of insulin sensitizers currently available is limited in use due to side effects We designed ISIS-PTP1BRx to act as an insulin sensitizer to enhance glycemic control by specifically targeting protein-tyrosine phosphatase 1B (PTP-1B). The results from this study and our earlier clinical experience with PTP-1B suggest that addressing this novel therapeutic target for type 2 diabetes with ISIS-PTP1BRx may have the potential to offer a safer more effective approach for patients with type 2 diabetes who are progressing in their disease," said
"ISIS-PTP1BRx is a drug that has the potential to address several unique segments of the type 2 diabetes population and has the potential to both delay the need for insulin as well as to make insulin therapy more effective, thereby addressing a significant unmet medical need. We and our advisors believe that ISIS-PTP1BRx could be developed for patients with type 2 diabetes who are failing oral antidiabetic therapies or GLP-1 agonists, thereby delaying the need to initiate insulin therapy. These data also support the development of ISIS-PTP1BRx for patients who are insulin-resistant, remain uncontrolled even on high doses of insulin and in whom an insulin sensitizer could provide significant benefit. In addition, the combination of glucose control and weight loss demonstrated by ISIS-PTP1BRx in this study has the potential to be a significant advance in the treatment of obese patients with type 2 diabetes. We are in the process of discussing future development plans with potential partners in the diabetes space who could provide the expertise and resources necessary to enhance the value of this drug," said
The Phase 2 study of ISIS-PTP-1BRx was a double-blinded, randomized, placebo-controlled study in 92 patients with type 2 diabetes who had uncontrolled blood sugar despite treatment with stable metformin with or without sulfonylurea therapy. Patients received 200 mg of ISIS-PTP1BRx or placebo for 26 weeks added to their stable doses of their background therapies. In this study, the average incoming HbA1c level was 8.6 percent and the average BMI was 34 kg/m2. Patients in this study were not required to conform to any type of restrictive or weight-loss diet beyond the standard dietary restrictions they adhered to upon entry into the study. In this study, ISIS-PTP1BRx was generally well tolerated. The most common adverse event was infrequent injection site reactions, which were predominantly mild and resolved rapidly. There were no flu-like symptoms, no clinically significant abnormalities in laboratory parameters and no cases of severe hypoglycemia.
