What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests OCTAPLEX, a medication that helps blood to clot, in patients with severe bleeding who are on blood thinners. It works by providing essential proteins needed for blood clotting.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does require that you are on an oral factor Xa inhibitor. Some medications like ticlopidine, prasugrel, ticagrelor, dipyridamole, and cangrelor must not have been taken within a certain period before the bleeding event.

Is the clotting medication Octaplex generally safe for humans?

Bleeding complications are a common side effect of medications that prevent abnormal blood clotting, like anticoagulants and antiplatelet drugs. These complications can be serious, but better clinical management has reduced severe reactions over time.12345

How does the drug Octaplex differ from other treatments for major bleeding?

Octaplex is unique because it is a coagulation factor concentrate, which means it directly provides the necessary components to help blood clot, unlike other treatments that may work by inhibiting bleeding pathways or enhancing platelet function. This makes it particularly useful in situations where conventional hemostatic therapies are ineffective.678910

Are You a Good Fit for This Trial?

Adults (≥18 years) on oral factor Xa inhibitor therapy with acute major bleeding, defined as life-threatening or uncontrolled bleeding, symptomatic critical organ bleeding, or significant drop in hemoglobin. Participants must have anti-factor Xa activity ≥100 ng/mL and provide informed consent. Excluded are those with recent trauma, certain cardiovascular events, coagulation disorders, known hypersensitivity to plasma products, prior use of specific haemostatic agents for the current bleed or participation in another clinical trial within the last month.

Inclusion Criteria

I am taking blood thinners and my baseline anti-factor Xa activity is at least 100 ng/mL.
Patients who have given written informed consent or for whom written informed consent has been obtained from the patient's legally authorised representative
I am currently experiencing severe bleeding.

Exclusion Criteria

Pregnant or breastfeeding patients at the time of enrollment
I have had a heart attack, stroke, or blood clot in the last 3 months.
Patients with Hgb decrease without accompanying evidence of source of bleeding

What Are the Treatments Tested in This Trial?

Interventions

  • Octaplex
Trial Overview The study is testing OCTAPLEX's effectiveness and safety at two different doses for patients experiencing severe bleeding while on DOAC therapy with a factor Xa inhibitor. It's a phase 3 trial where participants are randomly assigned to receive either a low-dose or high-dose of OCTAPLEX in an adaptive design that allows modifications based on interim results.

Published Research Related to This Trial

Anticoagulants and antiplatelet drugs are the most frequently reported causes of adverse drug reactions (ADRs) in Germany, with heparins, ticlopidine, phenprocoumon, acetylsalicylic acid, and clopidogrel being the most commonly implicated drugs.
There has been a notable reduction in severe ADRs, such as fatal cerebral hemorrhages, due to improved management of oral anticoagulant therapy and better handling of adverse events related to heparin.
