Certolizumab pegol: A pegylated anti-TNF-alpha antibody fragment for the treatment of Crohn's disease

January 01, 2008

Two tumor necrosis factor-alpha (TNF-alpha) inhibitors, infliximab and adalimumab, are approved by FDA for the treatment of moderate-to-severe Crohn's disease (CD) in patients who have an inadequate response to conventional therapies. Certolizumab is a pegylated TNF-alpha inhibitor being investigated for the treatment of moderate-to-severe CD.

Sitagliptin: The first dipeptidyl peptidase IV inhibitor for the treatment of type 2 diabetes

September 01, 2006

A variety of clinical approaches are utilized in the management of poor glycemic control in patients with type 2 diabetes. Sitagliptin (Januvia, Merck), a novel drug in a new medication class known as dipeptidyl peptidase-IV (DPP-IV) inhibitors, offers a new mechanism by which to achieve glycemic control. Although stimulation of receptors by the glucagon-like peptide-1 (GLP-1) enhances the body's ability to produce insulin in response to elevated blood glucose concentrations, rapid degradation of GLP-1 by DPP-IV limits its clinical effectiveness. The development of medications to reduce this degradation is being pursued by numerous manufacturers. An NDA for the first of these medications, sitagliptin, was submitted to FDA in February 2006. Currently available clinical studies have demonstrated improved glycemic control with sitagliptin therapy in patients who have not achieved target glucose levels with diet and oral medications.
