Head-to-Head safety check: which Clot-Reversal drug is safer before emergency surgery?

NCT ID NCT06429787

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

Summary

This observational study compares the safety of two drugs, BALFAXAR and KCENTRA, used to reverse the effects of vitamin K antagonist blood thinners (like warfarin) in adults who need urgent surgery or an invasive procedure. The main goal is to see how often blood clots (thromboembolic events) occur within 45 days after treatment. The study will follow about 3,500 participants to determine if one drug has a better safety profile.

What this could mean

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

Active substance
BALFAXAR (prothrombin complex concentrate, human-lans) and KCENTRA (prothrombin complex concentrate, human)
What this could lead to
If BALFAXAR proves safer than KCENTRA, it could become a preferred option for reversing blood thinners before emergency procedures, reducing complication risks.
What could go wrong
This is an observational study, not a randomized trial, so results may be influenced by patient differences. The study only looks at short-term safety, not long-term outcomes.
