Glycemic Control, Safety and Tolerability of TC-6987 Monotherapy in Type 2 Diabetes Mellitus

Completed · Phase 2 · Has a placebo group

Conditions studied: Type 2 Diabetes Mellitus

In brief

TC-6987 is a selective nicotinic α-7 receptor ligand (open channel stabilizer) that has demonstrated potent anti-inflammatory/antioxidant properties in animal models. Following the oral administration of a 1mg/kg dose of TC-6987 to diabetic mice (db/db mouse) for 7 weeks, numerous metabolic improvements were observed. Specifically, plasma glucose and triglyceride concentrations declined by approximately 30%; Hb1Ac was reduced by nearly 50%; and TNF-α declined more than 60% relative to control db/db mice Therefore, it appears that TC-6987 could prove beneficial in reducing elevated glucose concentrations in diabetic patients as well as in ameliorating organ damage associated with inflammation, oxidative stress and hyperglycemia.
