A Trial to Learn How Well REGN9933 and REGN7508 Work for Preventing Blood Clots, and How Safe They Are, in Adults Who Have a Peripherally Inserted Central Catheter (PICC)

Phase 2
Recruiting
Conditions
Venous Thromboembolism
Interventions
Registration Number
NCT06299111
Lead Sponsor
Regeneron Pharmaceuticals
Brief Summary

This study is researching 2 different experimental drugs called REGN9933 and REGN7508 (called "study drugs"). The study is focused on adults undergoing a placement of a catheter in your vein, also called a 'PICC line'.

The aim of the study is to see how effective the study drug is at preventing venous thromboembolism (VTE) and other related disease after catheter placement.

The study is looking at several other research questions, including:

* What side effects may happen from taking the study drug

* How much study drug is in your blood at different times

* Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
