What is the treatment for an apical thrombus in a patient already on Eliquis (apixaban)?

From the Guidelines

The treatment for an apical thrombus in a patient already on Eliquis (apixaban) typically involves intensifying anticoagulation therapy, with options including increasing to a higher dose of apixaban, switching to a different anticoagulant, or adding a second antithrombotic agent. For patients experiencing a thrombus while on standard apixaban dosing (5mg twice daily), the most recent and highest quality study 1 suggests that apixaban is significantly better than warfarin in preventing overall strokes and systemic emboli, with fewer major bleeding events. However, the study does not provide direct guidance on the management of apical thrombus in patients already on apixaban. Considering the patient's specific clinical situation, including kidney function, bleeding risk, and the suspected reason for anticoagulation failure, the choice between intensifying apixaban therapy, switching to warfarin with a target INR of 2.5-3.5, or adding a second antithrombotic agent like low-dose aspirin (81mg daily) should be individualized. Treatment duration should be at least 3-6 months, with follow-up imaging to confirm thrombus resolution before considering any reduction in therapy. Patients should be closely monitored for bleeding complications, especially if on intensified regimens. The goal of treatment is to prevent embolization of the thrombus, which could lead to stroke or systemic embolism, and addressing any underlying causes, such as atrial fibrillation or left ventricular dysfunction, is also essential for comprehensive management. Key considerations in managing apical thrombus in patients on apixaban include:

• Monitoring for signs of thromboembolism and bleeding complications
• Adjusting anticoagulation therapy based on individual patient risk factors and response to treatment
• Considering the use of additional antithrombotic agents or alternative anticoagulants as needed
• Regular follow-up imaging to assess thrombus resolution and guide treatment decisions.

From the FDA Drug Label

1.3 Treatment of Deep Vein Thrombosis Apixaban tablets are indicated for the treatment of DVT.

1.4 Treatment of Pulmonary Embolism Apixaban tablets are indicated for the treatment of PE.

The treatment for an apical thrombus in a patient already on Eliquis (apixaban) is not directly addressed in the FDA drug label. However, apixaban is indicated for the treatment of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE).

• Since the patient is already on apixaban, the current dose may be continued, but this decision should be made by a healthcare professional.
• The FDA drug label does not provide specific guidance on the treatment of apical thrombus with apixaban, and the optimal treatment approach may depend on various factors, including the patient's individual clinical characteristics and medical history 2.

From the Research

Treatment for Apical Thrombus

The treatment for an apical thrombus in a patient already on Eliquis (apixaban) can be considered based on the available evidence.

• The use of apixaban for the treatment of an LV thrombus has been reported in a case study, where a patient with a large, mobile thrombus within the left ventricular apex showed complete resolution of the thrombus after 6 days of receiving apixaban 3.
• Apixaban has been shown to be effective in reducing the risk of recurrent venous thromboembolism without increasing the rate of major bleeding 4, 5.
• However, it is essential to note that apixaban is not licensed for the treatment of an LV thrombus, and large, randomized research trials comparing NOACs and VKAs in the treatment of LV thrombus are needed 3.

Considerations for Treatment

• The decision to continue or adjust anticoagulation therapy in a patient with an apical thrombus already on Eliquis should be made on a case-by-case basis, taking into account the individual patient's risk factors and medical history.
• The available evidence suggests that apixaban may be a viable option for the treatment of an apical thrombus, but more research is needed to fully understand its efficacy and safety in this context 3, 6.
• Other factors, such as the patient's renal function, liver function, and bleeding risk, should also be considered when making treatment decisions 7, 6.
