ONCE-DAILY LIXIANA® FOR YOUR ELIGIBLE PATIENTS WITH NVAF
INDICATIONS1
LIXIANA® is indicated for:
-
Prevention of stroke and systemic embolism in adult patients with nonvalvular atrial fibrillation (NVAF) with one or more risk factors, such as congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke or transient ischaemic attack (TIA)
-
Treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and prevention of recurrent DVT and PE in adults
SIMPLE AND CONVENIENT FOR PATIENTS AND PRESCRIBERS4
-
Once-daily dosing, with or without food
EFFICACY AND SAFETY IN NVAF
PROVEN EFFICACY IN PREVENTING STROKE AND SEE IN NVAF PATIENTS – COMPARABLE TO WELL-CONTROLLED WARFARIN
-
LIXIANA® was comparable to well-controlled warfarin in the prevention of stroke and SEE in the modified intention-to-treat population (primary efficacy endpoint)2
-
In NVAF patients with high CrCl, there is a trend towards decreasing efficacy with increasing CrCl for edoxaban vs well-managed warfarin, therefore careful evaluation of thromboembolic and bleeding risk is necessary before initiation
STROKE/SEE IN THE INTENTION-TO-TREAT POPULATION DURING THE OVERALL STUDY PERIOD2
Numbers presented are from the intention-to-treat population with 97.5% CI and P values for superiority.
Noninferiority was tested in the modified intention-to-treat on-treatment population who received at least one dose of study drug.
-
Patients on the 30 mg reduced dose achieved efficacy consistent with overall trial results2
a Includes patients taking LIXIANA® 60 mg and those dose-reduced to 30 mg.

SUPERIOR REDUCTION IN MAJOR BLEEDING IN NVAF PATIENTS VS. WELL-CONTROLLED WARFARIN
ANNUAL RATE OF MAJOR BLEEDING EVENTS (PRIMARY SAFETY ENDPOINT) IN THE SAFETY ON-TREATMENT POPULATION2
-
Patients on the 30 mg reduced dose achieved a reduction in major bleeding consistent with overall trial results2
a Includes patients taking LIXIANA® 60 mg and those dose-reduced to 30 mg
The primary safety endpoint was the incidence of adjudicated major bleeding,3 defined by the International Society on Thrombosis and Haemostasis (ISTH) as (i) fatal bleeding; and/or (ii) symptomatic bleeding in critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intraarticular, pericardial, or intramuscular with compartment syndrome, and/or (iii) bleeding causing a fall in haemoglobin level of 2.0 g/dL or more, or leading to transfusion of two or more units of whole blood or red cells.3

EFFICACY AND SAFETY IN DVT AND PE
PROVEN EFFICACY IN THE TREATMENT AND PREVENTION OF RECURRENT VTE – COMPARABLE TO WELL-CONTROLLED WARFARIN
FIRST RECURRENT VTE EVENTS (PRIMARY EFFICACY ENDPOINT) DURING OVERALL STUDY AND ON-TREATMENT PERIODS4
-
Patients on the 30 mg reduced dose achieved efficacy consistent with overall trial results4
-
In NVAF patients with high CrCl, there is a trend towards decreasing efficacy with increasing CrCl for edoxaban vs well-managed warfarin, therefore careful evaluation of thromboembolic and bleeding risk is necessary before initiation
* The overall study period included the period of randomisation through to the end of 12 months or study closure4
a Includes patients taking LIXIANA® 60 mg and those dose-reduced to 30 mg.
SUPERIOR REDUCTION IN CLINICALLY RELEVANT BLEEDING IN VTE PATIENTS VS. WELL-CONTROLLED WARFARIN
COMPOSITE OF MAJOR AND CLINICALLY RELEVANT NONMAJOR BLEEDING EVENTS (PRIMARY SAFETY ENDPOINT) DURING ON-TREATMENT PERIOD4
-
Patients on the 30 mg reduced dose achieved a reduction in clinically relevant bleeding consistent with overall trial results4
a Includes patients taking LIXIANA® 60 mg and those dose-reduced to 30 mg.
The primary safety endpoint was a composite of major and clinically relevant nonmajor bleeding,4 as defined by the International Society on Thrombosis and Haemostasis (ISTH). Major bleeding was defined as overt bleeding associated with a decrease in haemoglobin of 2.0 g/L or more, or requiring a transfusion of 2 or more units of blood, occurring in a critical site or contributing to death.3 Clinically relevant non major bleeding was defined as overt bleeding not meeting the criteria for major bleeding but associated with medical intervention, unscheduled contact (visit or telephone call) with a physician, (temporary) cessation of study treatment, or associated with other discomfort such as pain, or impairment of daily life activities.5
DOSING
THE RECOMMENDED DOSE OF LIXIANA® IS 60 MG IN A ONCE-DAILY TABLET1
It can be taken with water, with or without food. To aid compliance, patients should be encouraged to take their dose at the same time every day.
Treatment with LIXIANA® in patients with NVAF should be continued long term.
The duration of treatment for VTE and prevention of recurrent VTE should be individualised after assessment of the treatment benefit against the risk for bleeding. Short duration of therapy (at least 3 months) should be based on transient risk factors (e.g. recent surgery, trauma, immobilisation) and longer durations should be based on permanent risk factors or idiopathic DVT or PE.
INITIATING TREATMENT1
For the treatment of VTE, patients should receive an initial course of heparin for at least 5 days prior to treatment with LIXIANA®. This is not required for the initiation of LIXIANA® in patients with NVAF for the prevention of stroke and systemic embolism.
Renal function (CrCl) and liver function should be assessed in all patients prior to LIXIANA® initiation. In NVAF patients with high CrCl, there is a trend towards decreasing efficacy with increasing CrCl for edoxaban vs well-managed warfarin, therefore careful evaluation of thromboembolic and bleeding risk is necessary before initiation.
Information on switching patients to LIXIANA® from other treatments can be found on the page SWITCHING TO AND FROM LIXIANA®
DOSE REDUCTION1
A dose of 30 mg once daily is required for certain patients who fall into one or more of the following subgroups.
These are:
In this case, patients should take one 30 mg tablet at the same time every day, with or without food.
MISSED DOSE1
If a patient misses a dose of LIXIANA® he/she should take it immediately and then continue the following day with the once-daily intake as recommended.
The patient should not take double the prescribed dose on the same day to make up for a missed dose.
SWITCHING TO AND FROM LIXIANA®
Switching patients to or from treatment with LIXIANA® is the same for both the VTE and NVAF indications. It should be noted that once a patient is switched to treatment with LIXIANA®, International Normalised Ratio (INR), prothrombin time (PT), or activated partial thromboplastin time (aPTT) are not useful measurements for anticoagulation effect.1
FROM NON-VKA ORAL ANTICOAGULANTS (NOAC) TO LIXIANA1
Discontinue the NOAC and start LIXIANA® at the time of the next non-VKA dose.
FROM LIXIANA® TO NOAC1
Discontinue LIXIANA® and start the NOAC at the time of the next scheduled dose of LIXIANA®.
FROM VKA THERAPY TO LIXIANA1
When converting patients from VKA therapy to LIXIANA®, discontinue warfarin or other VKA therapy and start LIXIANA® treatment when the INR is ≤ 2.5.
FROM LIXIANA® TO VKA THERAPY1
ORAL OPTION
There is a potential for inadequate anticoagulation during the transition from LIXIANA® to VKA. Continuous adequate anticoagulation should be ensured during any transition to an alternate anticoagulant. For patients currently on a 60 mg dose, administer a LIXIANA® dose of 30 mg once daily together with an appropriate VKA dose. For patients currently on a 30 mg dose, administer a LIXIANA® dose of 15 mg once daily together with an appropriate VKA dose.
Patients should not take a loading dose of VKA in order to promptly achieve a stable INR between 2 and 3. It is recommended to take into account the maintenance dose of VKA and if the patient was previously taking a VKA or to use valid INR driven VKA treatment algorithm, in accordance with local practice.
Once an INR ≥ 2.0 is achieved, LIXIANA® should be discontinued. Most patients (85%) should be able to achieve an INR ≥ 2.0 within 14 days of concomitant administration of LIXIANA® and VKA. After 14 days it is recommended that LIXIANA® is discontinued and the VKA continued to be titrated to achieve an INR between 2 and 3. It is recommended that during the first 14 days of concomitant therapy the INR is measured at least 3 times just prior to taking the daily dose of LIXIANA to minimise the influence of LIXIANA on INR measurements. Concomitant LIXIANA and VKA can increase the INR post LIXIANA dose by up to 46%.
PARENTERAL ROUTE1
Discontinue LIXIANA® treatment and administer a parenteral anticoagulant and VKA treatment at the time of the next scheduled LIXIANA® dose. Once a stable INR of ≥ 2.0 is achieved, the parenteral anticoagulant should be discontinued and the VKA continued.
FROM PARENTERAL ANTICOAGULANT TO LIXIANA1
LIXIANA® should not be administered simultaneously with a parenteral anticoagulant.
Patients on continuously administered parenteral drug such as intravenous (IV) unfractionated heparin:
Patients on subcutaneous anticoagulant (low molecular weight heparin (LMWH), e.g. fondaparinux):
FROM LIXIANA® TO PARENTERAL ANTICOAGULANT1
LIXIANA® should not be administered simultaneously with a parenteral anticoagulant.
Discontinue LIXIANA® and start the parenteral anticoagulant at the time of the next scheduled dose of LIXIANA®.
CONTRAINDICATIONS
As an anticoagulant, LIXIANA® may increase the risk of bleeding. Therefore, patients prescribed LIXIANA® should be carefully observed for signs of bleeding.1

SPECIAL PATIENT POPULATIONS
Several groups of patients are at increased risk of bleeding and should be carefully monitored for signs and symptoms of bleeding complications. Any treatment decision must be based on careful assessment of the treatment benefit against risk of bleeding.1
Prior to initiation of LIXIANA® and when clinically indicated, renal function testing (CrCl) should be performed

Dose reduction to 30 mg once daily (OD) (see the page “DOSE REDUCTION”) |
Mild renal impairment (CrCl >50–80 ml/min) |
No dose reduction required – 60 mg OD |
Renal function in NVAF |
|
---|---|
Patients with NVAF and high creatinine clearance |
There is a trend towards decreasing efficacy with increasing CrCl for edoxaban vs well-managed wararin, therefore careful evaluation of thromboembolic and bleeding risk is necessary before initiation |

Not recommended |
Selective serotonin reuptake inhibitors (SSRIs)/Serotonin and norepinephrine reuptake inhibitors (SNRIs) |
Possibility of increased risk of bleeding |
TEMPORARY DISCONTINUATION1
Breaks in therapy should be avoided wherever possible. However, in an instance where a temporary discontinuation is unavoidable (e.g. before a surgical intervention or invasive procedure), LIXIANA® should be restarted as soon as possible.
PERIOPERATIVE MANAGEMENT1
In situations where a patient requires a surgical intervention or invasive procedure (including tooth extraction), LIXIANA® should be stopped as soon as possible and preferably at least 24 hours beforehand, and appropriate caution exercised due to the increased risk of thrombosis. The half-life of LIXIANA® is 10–14 hours.
In deciding whether a procedure should be delayed until 24 hours after the last dose of LIXIANA®, the increased risk of bleeding should be weighed against the urgency of the intervention. LIXIANA® should be restarted after the surgical or other procedures as soon as adequate haemostasis has been established, noting that the time to onset of the LIXIANA® anticoagulant therapeutic effect is 1–2 hours. If oral medicinal products cannot be taken during or after surgical intervention, consider administering a parenteral anticoagulant and then switch to oral once-daily LIXIANA®.
OVERDOSE1
Overdose with LIXIANA® may lead to haemorrhage. A specific antidote antagonising the pharmacodynamic effect of LIXIANA® is not available. Early administration of activated charcoal may be considered in case of LIXIANA® overdose to reduce absorption. This recommendation is based on standard treatment of drug overdose and data available with similar compounds, as the use of activated charcoal to reduce absorption of LIXIANA® has not been specifically studied in the LIXIANA® clinical programme.
MANAGEMENT OF BLEEDING COMPLICATIONS1
If bleeding complications are experienced, treatment should be delayed or discontinued, taking the half-life of LIXIANA® (10–14 hours) into account.
Management should be individualised according to the severity and location of the haemorrhage:
-
Symptomatic treatment, such as mechanical compression, surgical haemostasis with bleeding control procedures, fluid replacement and haemodynamic support, blood product or platelets
-
For life-threatening bleeding that cannot be controlled with measures such as transfusion or haemostasis, the administration of a 4-factor prothrombin complex concentrate (PCC) at 50 IU/kg has been shown to reverse the effects of LIXIANA® 30 minutes after completing the infusion
Recombinant factor VIIa (r-FVIIa) can also be considered. However, there is limited clinical experience with the use of this product in individuals receiving LIXIANA®.
Haemodialysis does not significantly contribute to LIXIANA® clearance.
ROUTINE COAGULATION TESTING1
Treatment with LIXIANA® does not require routine clinical coagulation monitoring. As a result of Factor Xa inhibition, LIXIANA® prolongs standard clotting tests such as INR,prothrombin time (PT), or activated partial thromboplastin time (aPTT). Changes observed in these clotting tests at the expected therapeutic dose are small and subject to a high degree of variability. These tests are therefore not recommended to assess the pharmacodynamic effects of LIXIANA®.
There are no specific blood tests or assays available for LIXIANA®.
