What side effects are associated with this type of intervention?

Common treatments for Deep Vein Thrombosis (DVT) include low-molecular-weight heparins (e.g., dalteparin), direct oral anticoagulants (DOACs) such as rivaroxaban and apixaban, and vitamin K antagonists like warfarin. The primary side effect of these anticoagulants is an increased risk of bleeding, which can range from minor bruising to severe hemorrhage. Other side effects may include gastrointestinal issues, liver enzyme elevation, and, in the case of heparins, potential for heparin-induced thrombocytopenia (HIT). For Factor XI inhibitors like Abelacimab, the side effect profile is still being studied, but bleeding risk remains a primary concern.

What prior FDA approvals exist?

The FDA has approved several anticoagulants for the treatment of Deep Vein Thrombosis (DVT). These include direct oral anticoagulants (DOACs) such as dabigatran, rivaroxaban, apixaban, and edoxaban, which inhibit thrombin or Factor Xa. Low-molecular-weight heparins (LMWH) like enoxaparin have also been approved. While Factor XI inhibitors like Abelacimab are currently under study, they represent a novel approach to anticoagulation by targeting a different part of the coagulation cascade compared to traditional therapies.

What other types of research exist?

Promising novel alternatives to Abelacimab for DVT patients include: 1) Concizumab, an anti-TFPI antibody, which has shown efficacy in hemophilia and is being investigated for broader anticoagulation use. 2) Mim8, a bispecific antibody that mimics Factor VIIIa, showing potential in severe vascular challenges. 3) Recombinant fusion proteins like rIX-FP and N9-GP, which offer extended half-lives and improved pharmacokinetics for better management of coagulation disorders.

Summary

This trial compares a new medication, Abelacimab, to another treatment, Dalteparin, in patients with GI or GU cancer who have had blood clots. The goal is to see which treatment better prevents new clots and reduces bleeding risks.

Who is the study for?

This trial is for adults with gastrointestinal or genitourinary cancer who have had a recent deep vein thrombosis or pulmonary embolism. They must be able to take blood thinners for at least 6 months and not have any planned major surgery, brain trauma, severe liver issues, uncontrolled high blood pressure, or a life expectancy under 3 months.

What is being tested?

The study compares Abelacimab to Dalteparin in preventing blood clot recurrence and managing bleeding risks in patients with certain cancers. It's an open-label trial where the effects of each treatment are evaluated by researchers unaware of which group participants belong to.

What are the potential side effects?

Potential side effects may include bleeding complications, allergic reactions to medication components, possible liver enzyme elevations, and other organ-specific inflammation due to the anticoagulant nature of both Abelacimab and Dalteparin.

Other Research

Common treatments for Deep Vein Thrombosis (DVT) include anticoagulants such as Factor XI inhibitors (e.g., Abelacimab), direct oral anticoagulants (DOACs) like rivaroxaban and apixaban, and low-molecular-weight heparin (LMWH). Factor XI inhibitors work by targeting and inhibiting Factor XI in the coagulation cascade, which reduces the formation of blood clots with potentially lower bleeding risks. DOACs inhibit Factor Xa or thrombin, preventing clot formation. LMWH enhances the activity of antithrombin, which inactivates thrombin and Factor Xa. These treatments are crucial for DVT patients as they prevent clot propagation and recurrence, reducing the risk of complications such as pulmonary embolism and post-thrombotic syndrome.
