Can a new drug outperform standard care for a rare liver disease in teens?

NCT ID NCT03678480

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether an experimental drug called HTD1801 can improve liver health in adolescents with primary sclerosing cholangitis (PSC), a rare disease that damages the bile ducts. Participants will receive either HTD1801 or the standard treatment, ursodeoxycholic acid (UDCA), to compare their effects on liver enzyme levels. The study aims to see if HTD1801 can reduce markers of liver damage better than the current therapy.

What this could mean

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

Active substance
HTD1801 capsules, 250mg, compared to ursodeoxycholic acid (UDCA) capsules, 125mg
What this could lead to
If successful, HTD1801 could offer a new treatment option for adolescents with primary sclerosing cholangitis, potentially improving liver health and slowing disease progression.
What could go wrong
This is an early-phase trial with a small number of participants, so results may not be conclusive. The drug may not prove more effective than UDCA, and there could be unforeseen side effects.
