Heart safety check for new myelofibrosis drug in healthy volunteers

NCT ID NCT07708272

First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time

Summary

This study evaluates whether a single dose of TQ05105, a JAK inhibitor being developed for myelofibrosis, affects the heart's electrical activity (QT interval) in healthy Chinese adults. Sixty participants receive TQ05105, placebo, and moxifloxacin (a positive control) in a crossover design. The main goal is to see if TQ05105 causes any heart rhythm changes, which is a key safety step before larger patient trials.

What this could mean

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

Active substance
TQ05105 tablets, a Janus kinase (JAK) inhibitor
What this could lead to
If this trial shows TQ05105 does not affect heart rhythm, it could support further development of this drug for myelofibrosis with a known cardiac safety profile.
What could go wrong
This is an early-phase study in healthy people, not patients. The drug may still cause heart issues in patients or fail in later trials for other reasons.
