THORNHILL, ON, Aug. 19, 2015 /CNW/ - The largest completed study to date on treatments to reduce recurrence of blood clots in cancer patients, sponsored by LEO Pharma, has now been published in JAMA (The Journal of American Medical Association) August 18, 2015.
The study showed that innohep® lowered the risk of recurrent venous thromboembolism (VTE) compared with warfarin with a significant reduction in symptomatic deep vein thrombosis and clinically relevant non-major bleeding in cancer patients with symptomatic venous thromboembolism.
Blood clots are one of the leading causes of death in patients with cancer.
Approximately 1 in 10 patients with cancer dies from a blood clot related event 1,2.
"Cancer patients with VTE have a substantial risk of blood clots, and optimal treatment to avoid recurrence is vital. Advancing knowledge within this area is therefore a high priority for us at LEO Pharma. We hope that the results from the CATCH study will help to further improve the management of blood clots in cancer patients" says Kim Kjoeller, Senior Vice President from LEO Pharma.
According to Xavier Bertin, President & CEO of LEO Pharma Canada, "The results of this contemporary study support the current Canadian Consensus Recommendations3 and demonstrate the safety of full dose innohep® over a six month period".
Despite clinical practice guidelines recommending the use of low-molecular-weight heparins (LMWH) like innohep®, warfarin remains a frequently used anticoagulant treatment worldwide for cancer patients with recurrent VTE3. The CATCH study sponsored by LEO Pharma supports the previous findings and the clinical practice guidelines.
The CATCH study is a Phase III, multinational, concealed, randomised, active-controlled, open-label trial with blinded adjudication. 900 cancer patients from Europe, Africa, Asia, North America and South America were enrolled in the study. 449 patients were treated with tinzaparin (innohep®) and 451 were treated with warfarin over a period of 180 days.
During the treatment period, 7.2% of the patients treated with innohep® experienced recurrent blood clots compared to 10.5% of the patients treated with warfarin.
Dr. Agnes Lee, MD, University of British Columbia and Vancouver Coastal Health in Canada and Principal Investigator of the CATCH study commented: "This global study reinforces clinical guidelines supporting the use of low-molecular-weight heparins instead of warfarin to prevent recurrent blood clots in these patients. Our results also offer the first look at other important issues in this high-risk population, including identification of biomarkers that may predict for higher risk of recurrent blood clots, quality of life and health care economics".
Notes to editors
innohep® is a low-molecular-weight heparin (LMWH) for subcutaneous injection for the treatment of venous thrombosis and thromboembolic disease including deep vein thrombosis (DVT) and pulmonary embolism (PE). innohep® is manufactured by LEO Pharma.
About the CATCH study
CATCH is the largest randomized study conducted to date on extended treatment with LMWH to prevent recurrence of VTE in patients with active cancer4. CATCH is a Phase III, multinational, concealed, randomised, active-controlled, open-label trial with blinded adjudication assessing the efficacy and safety of long-term (6 months) innohep® (tinzaparin sodium) therapy (175 IU/kg) versus anticoagulation with warfarin for the treatment of VTE in 900 cancer patients.

About Cancer Associated Thrombosis
For the general population, the standard treatment for acute VTE consists of initial therapy with a low-molecular-weight heparin (LMWH) followed by longer-term treatment (3–6 months) with an oral vitamin K antagonist (VKA). Although this approach can be effective for many patients, cancer patients have a substantial risk of recurrent VTE. Several studies have reported incidences of recurrent VTE as high as 20% in patients with cancer5,6. However, studies on how to treat and identify those at risk of recurrent VTE are limited7,8. Moreover, the frequent monitoring and dose adjustments required for VKA treatment have a negative impact on Quality of Life9.
Guidelines in Europe and North America recommend long-term treatment of symptomatic VTE in all cancer patients10,11,12,13. The major treatment objective is to reduce recurrent thrombosis, including fatal and non-fatal PE.
