ASTER Trial Summary

This trial will compare the effect of two different drugs on preventing blood clots and bleeding in cancer patients.

Who is the study for?
Adults diagnosed with cancer-associated venous thromboembolism (VTE), including deep vein thrombosis or pulmonary embolism, can join this trial if they've been diagnosed within the past 120 hours and need blood thinners for at least 6 months. They must not have used certain treatments for VTE, have specific medical conditions, or be on conflicting medications.Check my eligibility
What is being tested?
The study is testing Abelacimab against Apixaban to see which is better at preventing VTE from coming back and causing less bleeding in patients with cancer-related VTE. It's a Phase 3 trial where participants are randomly chosen to receive one of the two drugs.See study design
What are the potential side effects?
Potential side effects may include bleeding complications due to the blood-thinning nature of both Abelacimab and Apixaban. The exact side effects will vary between individuals based on their condition and response to treatment.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Time to first event of centrally adjudicated VTE recurrence consisting of new proximal deep venous thrombosis, new pulmonary embolism (PE) or fatal PE, including unexplained death for which PE cannot be ruled out
Secondary outcome measures
Net clinical benefit defined as survival without VTE recurrence, or major or CRNM bleeding
Time to first event of ISTH-adjudicated major or clinically relevant non-major (CRNM) bleeding events
