New combo shot shows promise for Tough-to-Control diabetes
NCT ID NCT05114590
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed Phase 4 study tested Soliqua 100/33, a once-daily injectable combining insulin and a GLP-1 drug, in 124 adults with very uncontrolled type 2 diabetes (HbA1c ≥9%) who were not yet on insulin. The goal was to see if the drug increased the time their blood sugar stayed in a healthy range, measured by continuous glucose monitors over 16 weeks. Participants continued their usual oral diabetes medications during the study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Soliqua 100/33 (insulin glargine and lixisenatide combination)
- What this could lead to
- If successful, this could offer a new treatment option to help people with very uncontrolled type 2 diabetes achieve better daily blood sugar control without starting insulin.
- What could go wrong
- This is a small, single-arm Phase 4 study with no comparison group, so results may not be definitive. The drug can cause hypoglycemia and gastrointestinal side effects.
