Phase II Study of Glycemic Control, Safety, Tolerability and Pharmacokinetic Parameters of TC-6987 Monotherapy in Subjects With Type 2 Diabetes Mellitus
Brief description: 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.
Detailed description: This is a Phase II, multicenter, randomized, double-blind, parallel group, placebo-controlled study to assess the efficacy, safety, tolerability, and pharmacokinetic parameters of TC-6987 in subjects with type 2 diabetes mellitus (T2DM). The study is organized into three phases: (a) Screening phase consisting of a 1-week Screening (Week -5)and a 4-week Washout (Week -4 to Day 1); (b) 4-week, Double-Blind Treatment (Day 1 to Week 4) during which subjects are randomized to either TC-6987 (20 mg on Day 1 and 10 mg from Day 2 to Week 4) or placebo; and (c) 2-week Follow-Up (Week 6). Unscheduled visits will be allowed between visits from Washout through Follow-up to evaluate a subject's glycemic status or other safety issues, as required. Subjects will fast overnight for a minimum of 10 hrs and refrain from drinking alcohol 24 hrs prior to each visit.
