Venous thromboEmbolism Network U.S. (VENUS)


The Venous thromboEmbolism Network U.S. (“VENUS”) is a collaborative U. S. research network organized under the auspices of the Hemostasis and Thrombosis Research Society, Inc. (“HTRS”).

The purpose of VENUS is to initiate and implement collaborative, multi-institutional, investigator-initiated clinical trials and/or other scientific research projects focused on thrombotic disorders in the United States (U.S.). VENUS members are individual physician-scientists employed at various academic medical or other non-commercial research institutions in the U.S. At present, there are an estimated 90 individual investigators employed at 60-70 institutions participating in VENUS.

VENUS members are organized into committees based on their research focus. Each VENUS committee is charged with organizing collaborative, multi-institutional research projects, including clinical trials, and applying for grant funds to support any proposed projects.


VENUS is a member of INVENT (International Network of VENous Thromboembolism Clinical Research Networks).

INVENT is an independent, not-for-profit network of academic research groups.  INVENT exists to promote international collaboration between academic research networks that conduct venous thromboembolism (VTE) related clinical research, and to enhance the profile, science, and impact of investigator-led VTE clinical research.
