Study Summary

The objective of this study is to prospectively develop a risk assessment model (RAM) that accurately identifies anticoagulated cancer-associated thrombosis (CAT) patients at low- and high-risk of recurrent venous thromboembolism (VTE) and clinically relevant bleeding within 6 months following the CAT diagnosis and to create a biobank of plasma and whole blood samples for further translational research in cancer genetics and hemostasis.

Eligibility Criteria

Inclusion

Inclusion Criteria:

Study Description

CAN-CATCH study is a prospective cohort study to develop a risk assessment model for VTE recurrence and clinically relevant bleeding in patients with CAT. The study is anticipated to recruit for a period of 2 years with a 3-year completion timeline.

The primary objective of this study is to prospectively develop a RAM that accurately identifies anticoagulated CAT patients at low- and high-risk of CAT recurrence and clinically relevant bleeding within 6 months following the CAT diagnosis.

The secondary objective is to create a biobank of plasma and DNA samples at the time of CAT diagnosis, linked to the annotated dataset for future translational biomarker research in cancer genetics and hemostasis.

At approved sites, participants will donate 4x4.5 mL 3.2% citrate tubes and 3x10 mL ethylenediaminetetraacetic (EDTA) tubes for blood banking.

In addition to the initial enrollment visit, participants that are enrolled will have a follow up at day 90 ± 14 days (3 months) and at day 180 ± 14 days (6 months) from randomization. Post enrollment follow-up visits will include assessment and documentation of any major and clinically relevant non-major bleeding (CRNMB), investigations for VTE, change in cancer treatment regimen, VTE risk factors, bleeding risk factors and death. Participants who experience an outcome event should continue to be followed
