NCT ID NCT00707954
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested an experimental drug called TA-7284 in 61 adults with type 2 diabetes. Participants took different doses (25 to 400 mg) or a placebo once daily for 15 days. The main goal was to check safety and how the drug moves through the body, with a secondary look at its effect on blood sugar and urine glucose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TA-7284 (an experimental oral diabetes drug)
- What this could lead to
- If successful, this could lead to a new daily pill to help control blood sugar in people with type 2 diabetes.
- What could go wrong
- This is a very early, small study (61 people) focused on safety and dosing, not on proving the drug works. Many drugs fail at this stage.
