New shot could replace pills to prevent clots after knee surgery

NCT ID NCT07015905

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests an experimental drug called REGN7508 (cenvacibart) to prevent venous thromboembolism (blood clots) in adults after elective total knee replacement. About 2,000 participants will receive either REGN7508, apixaban, or enoxaparin to compare effectiveness and safety. The goal is to see if REGN7508 works as well or better than standard blood thinners with fewer side effects.

What this could mean

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

Active substance

REGN7508 (cenvacibart), a monoclonal antibody that blocks factor XI to prevent blood clots

What this could lead to

If successful, REGN7508 could offer a new option to prevent dangerous blood clots after knee replacement surgery, potentially with fewer bleeding risks than current treatments.

What could go wrong

This is a large Phase 3 trial, but the drug is still experimental. It may not prove safer or more effective than existing blood thinners, and there is always a risk of unexpected side effects like bleeding or allergic reactions.
