New weekly shot could help diabetics with kidney trouble control blood sugar
NCT ID NCT06297603
First seen Jun 27, 2026 · Last updated Jul 21, 2026 · Updated 2 times
Summary
This study tests a once-weekly injection called retatrutide in 320 adults with type 2 diabetes and moderate to severe kidney disease who are not controlling their blood sugar well on insulin. Participants will receive either the drug or a placebo for about 14 months. The goal is to see if retatrutide safely improves blood sugar levels.
