Summary

This study compares continuing oral diabetes medications (like metformin) versus switching to insulin in hospitalized adults with type 2 diabetes. About 255 participants will be randomly assigned to either stay on their usual pills or receive insulin injections. The goal is to see if the pills can control blood sugar just as safely and effectively during a hospital stay.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
oral antidiabetic drugs (metformin, sulfonylureas, pioglitazone, DPP-4 inhibitors, SGLT2 inhibitors)
What this could lead to
If successful, this could show that many hospitalized patients with type 2 diabetes can safely keep taking their usual pills instead of switching to insulin, simplifying hospital diabetes care.
What could go wrong
This is a moderate-sized Phase 4 trial, so results may not apply to all patients. Oral drugs may not control blood sugar as tightly as insulin in some hospitalized patients, and there is a risk of hypoglycemia or other side effects.
