Summary

This phase 2 trial tested the safety and effectiveness of metformin extended release (XR) in 12 adults with type 2 diabetes and mild to moderate chronic kidney disease (stages 1 to 3). Participants took metformin XR tablets for 6 to 12 weeks, and researchers monitored their blood glucose levels continuously. The goal was to see if the drug could control blood sugar without causing harm, especially to the kidneys.

What this could mean

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

Active substance
metformin extended release (XR)
What this could lead to
If successful, this could show that metformin XR is safe and effective for managing blood sugar in type 2 diabetes patients with mild to moderate kidney disease.
What could go wrong
This is a small, early-phase study with only 12 participants, so results may not apply broadly. Metformin can rarely cause lactic acidosis, especially in kidney disease.
