Targeting INflammation Using SALsalate in Type 2 Diabetes (TINSAL-T2D)

Completed · Phase 2/Phase 3 · Has a placebo group

Conditions studied: Type 2 Diabetes

In brief

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 first stage is a dose ranging study, administering salsalate compared to placebo over three months. 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. The second stage is a second trial and posted under alternate registration.
