Purpose
Growing evidence over recent years supports a potential role for low grade chronic inflammation in the pathogenesis of insulin resistance and type 2 diabetes. In this study we will determine whether salsalate, a member of the commonly used Non-Steroidal Anti-Inflammatory Drug (NSAID) class, is effective in lowering sugars in patients with type 2 diabetes. The study will determine whether salicylates represent a new pharmacological option for diabetes management. The study is conducted in two stages. The primary objective of the first stage is to select a dose of salsalate that is both well-tolerated and demonstrates a trend toward improvement in glycemic control. The primary objective of Stage 2 of the study is to evaluate the effects of salsalate on blood sugar control in diabetes; the tolerability of salsalate use in patients with type 2 diabetes (T2D); and the effects of salsalate on measures of inflammation, the metabolic syndrome, and cardiac risk.

Primary Outcome Measures:
The primary outcome for the TINSAL-T2D study is change in HbA1c level from baseline to week 14 (stage 1) or 26 (stage 2) in the intent-to-treat (ITT) population with last observation carried forward. [ Time Frame: 14-26 week ]

Secondary Outcome Measures:
Change from baseline to either 14 or 26 weeks, or last HbA1c measurement prior to rescue therapy [ Time Frame: 14-26 week ]

Change from baseline and trends in fasting glucose over time [ Time Frame: 14-26 week ]

Response rates for reduction in fasting glucose of ¡Ý20 mg/dl, a reduction in HbA1c of ¡Ý0.5%, and a reduction in HbA1c of ¡Ý0.8% [ Time Frame: 14-26 week ]

Change in lipids (low-density lipoprotein cholesterol [LDL-C], non-high-density lipoprotein cholesterol [non-HDL-C], triglycerides [TG], total cholesterol [TC], high-density lipoprotein cholesterol [HDL C], TC/HDL-C ratio, and LDL-C/HDL-C ratio) [ Time Frame: 14-26 week ]

Change in insulin sensitivity (insulin, C-peptide, homeostasis model [HOMA] index) [ Time Frame: 14-26 week ]

Response rates for exceeding hyperglycemic targets between active and placebo treated groups [ Time Frame: 14-26 week ]

Need for rescue therapy [ Time Frame: 14-26 week ]

Need for discontinuation of study medication [ Time Frame: 14-26 week ]

Response rates in patients initially treated with lifestyle modification, insulin secretagogue, metformin or combination therapy [ Time Frame: 14-26 week ]

Response rates for a reduction in HbA1c for obese vs non-obese participants [ Time Frame: 14-26 week ]

Safety and tolerability of salsalate compared to placebo [ Time Frame: 14-26 weeks ]
