New shot could slash Sky-High cholesterol in teens with rare gene condition
NCT ID NCT04659863
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a drug called inclisiran in teenagers aged 12 to 18 who have a rare inherited condition that causes extremely high cholesterol. The goal was to see if the drug safely lowers their LDL (bad) cholesterol. Participants received either inclisiran or a placebo for one year, followed by open-label inclisiran for a second year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Inclisiran
- What this could lead to
- If successful, inclisiran could offer a new, convenient treatment option to lower dangerously high cholesterol in teenagers with this rare genetic condition.
- What could go wrong
- This is a small, early-phase study with only 13 participants, so results may not apply to all patients. Long-term safety and effectiveness are still unknown.
