NCT ID NCT07546929
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 trial tests HP-211, a botanical extract from common vegetables like endive and lettuce, in 300 people with type 2 diabetes. The goal is to see if it can improve how the body uses insulin and lower blood sugar levels over 90 days. Participants take HP-211 or a placebo twice daily, and researchers measure changes in HbA1c, a key blood sugar marker.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HP-211 (a botanical extract from endive, lettuce, and tarragon)
- What this could lead to
- If it works, HP-211 could offer a new, natural option to help control blood sugar and reduce insulin resistance in type 2 diabetes, potentially preventing or delaying complications.
- What could go wrong
- This is an early Phase 2 study with only 300 people, so results may not apply to everyone. The extract is new, and its long-term safety and effectiveness are not yet proven.
This is an AI summary of the original study and may miss details. Read our disclaimer.
