Full Prescribing Information
WARNING: SPINAL/EPIDURAL HEMATOMA
Epidural or spinal hematomas may occur in patients treated with betrixaban who are receiving neuraxial anesthesia or undergoing spinal puncture. The risk of these events may be increased by the use of in-dwelling epidural catheters or the concomitant use of medical products affecting hemostasis. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures [see Warnings and Precautions (5.2)].
1. Indications and Usage for Bevyxxa
BEVYXXA is indicated for the prophylaxis of venous thromboembolism (VTE) in adult patients hospitalized for an acute medical illness who are at risk for thromboembolic complications due to moderate or severe restricted mobility and other risk factors for VTE [see Clinical Studies (14)].
2. Bevyxxa Dosage and Administration
2.1 Recommended Dose
The recommended dose of BEVYXXA is an initial single dose of 160 mg, followed by 80 mg once daily. Daily oral doses should be given at the same time of day with food.
The recommended duration of treatment is 35 to 42 days.
2.2 Use with P-gp Inhibitors
For patients receiving or starting concomitant P-gp inhibitors the recommended dose of BEVYXXA is an initial single dose of 80 mg followed by 40 mg once daily [see Warnings and Precautions (5.4), Drug Interactions (7.1), Clinical Pharmacology (12.3)]. The recommended duration of treatment is 35 to 42 days.
2.3 Patients with Severe Renal Impairment
For patients with severe renal impairment (CrCl ≥ 15 to < 30 mL/min computed by Cockcroft-Gault using actual body weight) the recommended dose of BEVYXXA is an initial single dose of 80 mg followed by 40 mg once daily [see Warnings and Precautions (5.3), Use in Specific Populations (8.6), Clinical Pharmacology (12.3)]. The recommended duration of treatment is 35 to 42 days.
3. Dosage Forms and Strengths
Capsules:
- 80 mg (size 2) hard gelatin capsules have a light grey body with 80 printed in black and a blue cap with PTLA printed in white.

4. Contraindications
BEVYXXA is contraindicated in patients with:
- Active pathological bleeding [see Warnings and Precautions (5.1) and Adverse Reactions (6.1)]
- Severe hypersensitivity reaction to betrixaban [see Adverse Reactions (6.1)].
5. Warnings and Precautions
5.1 Risk of Bleeding
BEVYXXA increases the risk of bleeding and can cause serious and potentially fatal bleeding. Promptly evaluate any signs or symptoms of blood loss [see Adverse Reactions (6.1)].
Concomitant use of drugs affecting hemostasis increases the risk of bleeding. These include aspirin and other antiplatelet agents, other anticoagulants, heparin, thrombolytic agents, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs) [see Drug Interactions (7.3)].
Advise patients of signs and symptoms of blood loss and to report them immediately and seek emergency care. Promptly evaluate any signs or symptoms of blood loss and consider the need for blood replacement. Discontinue BEVYXXA in patients with active pathological bleeding.
There is no established way to reverse the anticoagulant effect of BEVYXXA, which can be expected to persist for at least 72 hours after the last dose. It is unknown whether hemodialysis removes BEVYXXA. Protamine sulfate, vitamin K, and tranexamic acid are not expected to reverse the anticoagulant activity of BEVYXXA.
5.2 Spinal/Epidural Anesthesia or Puncture
When neuraxial anesthesia (spinal/epidural anesthesia) or spinal/epidural puncture is employed, patients treated with antithrombotic agents for prevention of thromboembolic complications are at risk of developing an epidural or spinal hematoma which can result in long-term or permanent paralysis.
Do not remove an epidural catheter earlier than 72 hours after the last administration of BEVYXXA. Do not administer the next BEVYXXA dose earlier than 5 hours after the removal of the catheter. If traumatic puncture occurs, delay the administration of BEVYXXA for 72 hours.
Monitor patients frequently for signs and symptoms of neurological impairment (e.g., numbness or weakness of the legs, bowel or bladder dysfunction). If neurological compromise is noted, urgent diagnosis and treatment is necessary. Prior to neuraxial intervention, consider the potential benefit versus the risk in anticoagulated patients or in patients to be anticoagulated for thromboprophylaxis.
5.3 Use in Patients with Severe Renal Impairment
Patients with severe renal impairment (CrCl ≥ 15 to < 30 mL/min computed by Cockcroft-Gault using actual body weight) taking BEVYXXA may have an increased risk of bleeding events. Reduce dose of BEVYXXA, monitor patients closely, and promptly evaluate any signs or symptoms of blood loss in these patients [see Dosage and Administration (2.3), Warnings and Precautions (5.1), Adverse Reactions (6.1), Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
5.4 Use in Patients on Concomitant P-gp Inhibitors
Patients on concomitant P-gp inhibitors with BEVYXXA may have an increased risk of bleeding. Reduce dose of BEVYXXA in patients receiving or starting P-gp inhibitors. Monitor patients closely and promptly evaluate any signs or symptoms of blood loss in these patients [see Dosage and Administration (2.2), Warnings and Precautions (5.1), Adverse Reactions (6.1), Drug Interactions (7.1), Clinical Pharmacology (12.3)].
Avoid use of BEVYXXA in patients with severe renal impairment receiving concomitant P-gp inhibitors [see Warnings and Precautions (5.3)].
6. Adverse Reactions/Side Effects
The following clinically significant adverse reactions are described elsewhere in the labeling:
- Risk of Bleeding [see Warnings and Precautions (5.1, 5.3, 5.4)].
- Spinal/Epidural Anesthesia or Puncture [see Boxed Warning and Warnings and Precautions (5.2)].
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of BEVYXXA was evaluated in the Acute Medically Ill Prevention with Extended Duration Betrixaban (APEX) Study [see Clinical Studies (14)], including 3,716 patients treated with BEVYXXA for a median of 36 days compared to 3,716 patients treated with enoxaparin for a median of 9 days. Patients in both treatment groups were followed for safety, including bleeding events, for up to 77 days.
Patients randomized to the BEVYXXA arm received BEVYXXA 160 mg orally on Day 1, then 80 mg once daily for 35 to 42 days AND enoxaparin subcutaneous placebo once daily for 6 to 14 days. Patients randomized to the enoxaparin arm received enoxaparin 40 mg subcutaneously once daily for 6 to 14 days AND BEVYXXA placebo orally once daily for 35 to 42 days.
Patients with severe renal impairment (creatinine clearance ≥ 15 and < 30 mL/min) received reduced doses of study medications (BEVYXXA 80 mg loading dose, then 40 mg once daily or enoxaparin 20 mg once daily) along with corresponding placebo.
Patients taking a concomitant P-gp inhibitor received BEVYXXA 80 mg loading dose, then 40 mg once daily or enoxaparin 40 mg subcutaneously once daily for 6 to 14 days along with corresponding placebo.
Hemorrhage
The most common adverse reactions with BEVYXXA were related to bleeding (> 5%) with major bleeding occurring in less than 1% of patients (see Table 1).
Overall, 54% of patients receiving BEVYXXA experienced at least one adverse reaction vs. 52% with enoxaparin. The frequency of patients reporting serious adverse reactions was similar between BEVYXXA (18%) and enoxaparin (17%). In the APEX trial, the most frequent reason for treatment discontinuation was bleeding, with an incidence rate of 2.4% for BEVYXXA vs. 1.2% for enoxaparin.
The primary and secondary safety outcomes in APEX were bleeding-related events.
A summary of major and clinically relevant non-major (CRNM) bleeding events in the overall safety population is shown in Table 1. Most CRNM events (86%) were mild to moderate in severity, and the majority (62%) did not require medical intervention.
The incidence of fatal bleeding was the same in the BEVYXXA and enoxaparin treatment groups (1 in each group).

7. Drug Interactions
7.1 Inhibitors of P-gp
Betrixaban is a substrate of P-gp and concomitant use of P-gp inhibitors (e.g., amiodarone, azithromycin, verapamil, ketoconazole, clarithromycin) results in an increased exposure of betrixaban [see Clinical Pharmacology (12.3)].
Reduce the dose of BEVYXXA for patients receiving or starting concomitant P-gp inhibitors [see Dosage and Administration (2.2), Warnings and Precautions (5.4), Clinical Pharmacology (12.3)].
7.2 Inducers of P-gp
Co-administration of BEVYXXA with P-gp inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort) may result in a decrease in systemic exposure of betrixaban and its pharmacodynamic effects. Therefore, avoid the use of BEVYXXA in patients receiving P-gp inducers.
7.3 Anticoagulants, Antiplatelets, and Thrombolytics
Co-administration of anticoagulants, antiplatelet drugs, and thrombolytics may increase the risk of bleeding. Promptly evaluate any signs or symptoms of blood loss if patients are treated concomitantly with anticoagulants, aspirin, other platelet aggregation inhibitors, and/or NSAIDs [see Warnings and Precautions (5.1)].
8. Use In Specific Populations
8.5 Geriatric Use
Of the total number of patients in the APEX clinical study 90% were 65 years and over, while 68.6% were greater than or equal to 75 years. No clinically significant differences in safety or effectiveness were observed between older and younger patients.
8.6 Renal Impairment
Patients with severe renal impairment (CrCl ≥ 15 to < 30 mL/min computed by Cockcroft-Gault using actual body weight) may have an increased risk of bleeding events. Reduce the BEVYXXA dose for patients with severe renal impairment. Monitor patients closely and promptly evaluate any signs or symptoms of blood loss in these patients [see Dosage and Administration (2.3), Warnings and Precautions (5.3), Clinical Pharmacology (12.3)]. No dose adjustment is needed for mild or moderate renal impairment (CrCl > 30 mL/min, computed by Cockcroft-Gault using actual body weight).
8.7 Hepatic Impairment
In a pharmacokinetic study, compared to subjects with normal hepatic function, AUC increases of 30% were observed in subjects with mild hepatic impairment. No dose adjustment is required in patients with mild hepatic impairment.
Compared to subjects with normal hepatic function, AUC increases of 57% were observed in subjects with moderate hepatic impairment. The safety or PK of BEVYXXA in patients with severe hepatic impairment was not evaluated [see Clinical Pharmacology (12.3)]. Avoid the use of BEVYXXA in patients with moderate and severe hepatic impairment or with any hepatic disease associated with coagulopathy [see Clinical Pharmacology (12.3)].
10. Overdosage
Overdose of BEVYXXA increases the risk of bleeding [see Warnings and Precautions (5.1)].
A specific reversal agent for BEVYXXA is not available. There is no experience with hemodialysis in individuals receiving betrixaban. Protamine sulfate, vitamin K, and tranexamic acid are not expected to reverse the anticoagulant activity of betrixaban.
11. Bevyxxa Description
Betrixaban, a factor Xa (FXa) inhibitor, is chemically described as N-(5-chloropyridin-2-yl)-2-[4-(N,N-dimethylcarbamimidoyl)-benzoylamino]-5-methoxybenzamide in the form of maleate salt. The molecular formula of betrixaban maleate is C27H26ClN5O7, which corresponds to a molecular weight of 567.98. Betrixaban maleate has the following structural formula:
BEVYXXA capsules are available for oral administration in strengths of 80 mg and 40 mg of betrixaban, equivalent to 50.28 mg and 100.56 mg of betrixaban maleate, respectively. Each BEVYXXA capsule contains the following inactive ingredients: croscarmellose sodium, dextrose monohydrate, magnesium stearate in a hard gelatin capsule.
12. Bevyxxa - Clinical Pharmacology
12.1 Mechanism of Action
Betrixaban is an oral FXa inhibitor that selectively blocks the active site of FXa and does not require a cofactor (such as Anti-thrombin III) for activity. Betrixaban inhibits free FXa and prothrombinase activity. By directly inhibiting FXa, betrixaban decreases thrombin generation (TG). Betrixaban has no direct effect on platelet aggregation.
12.2 Pharmacodynamics
Inhibition of FXa by betrixaban results in an inhibition of thrombin generation at clinically relevant concentrations, and the maximum inhibition of thrombin generation coincides with the time of peak betrixaban concentrations.
12.3 Pharmacokinetics
Within the anticipated therapeutic dose range a two-fold increase in dose resulted in a three-fold increase in exposure in the single ascending dose study. A two-fold increase in betrixaban exposure was observed after repeat dosing, and the time to steady-state is 6 days (without an initial loading dose).
Distribution
The apparent volume of distribution is 32 L/kg. In vitro plasma protein binding is 60%.
13. Nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenicity studies with betrixaban have not been performed.
Betrixaban was not mutagenic in bacteria (Ames-Test) or clastogenic in Chinese hamster ovary cells in vitro or in the rat micronucleus test in vivo.
In a study to assess fertility and early embryonic development to implantation, oral doses of betrixaban were administered to male and female rats. There was no evidence that betrixaban up to 150 mg/kg/day adversely affected male or female fertility, reproductive performance, or embryo-fetal viability.
14. Clinical Studies
The clinical evidence for the effectiveness of BEVYXXA is derived from the APEX clinical trial [NCT01583218]. APEX was a randomized, double-blind, multinational study comparing extended duration BEVYXXA (35 to 42 days) to short duration of enoxaparin (6 to 14 days) in the prevention of venous thromboembolic events (VTE) in hospitalized, acutely medically ill patients with risk factors for VTE.
Eligible patients included adults who were at least 40 years of age, hospitalized for an acute medical illness, at risk for VTE due to moderate or severe immobility, and had additional risk factors for VTE (described below). Expected duration of hospitalization was at least 3 days and patients were expected to be moderately or severely immobilized for at least 24 hours. The causes for hospitalization included heart failure, respiratory failure, infectious disease, rheumatic disease, or ischemic stroke. At study initiation eligible patients were required to have one of the following additional risk factors for VTE:
- ≥ 75 years of age,
- 60 through 74 years of age with D-dimer ≥ 2 ULN, or
- 40 through 59 years of age with D-dimer ≥ 2 ULN and a history of either VTE or cancer.
A total of 7,513 patients were randomized 1:1 to:
- BEVYXXA arm (BEVYXXA 160 mg orally on Day 1, then 80 mg once daily for 35 to 42 days AND enoxaparin subcutaneous placebo once daily for 6 to 14 days),
OR - Enoxaparin arm (enoxaparin 40 mg subcutaneously once daily for 6 to 14 days AND BEVYXXA placebo orally once daily for 35 to 42 days).
Patients with severe renal impairment (creatinine clearance ≥ 15 and < 30 mL/min) received reduced doses of study medications (BEVYXXA 80 mg loading dose, then 40 mg once daily or enoxaparin 20 mg once daily) along with corresponding placebo.
Patients taking a concomitant P-gp inhibitor received BEVYXXA 80 mg loading dose, then 40 mg once daily or enoxaparin 40 mg subcutaneously once daily for 6 to 14 days along with corresponding placebo.
Baseline characteristics were balanced between the treatment groups. The population was 55% female, 93% White, 2% Black, 0.2% Asian, and 5% others. The most prevalent acute medical illness at hospitalization was acutely decompensated heart failure (45%), followed by acute infection without septic shock (29%), acute respiratory failure (12%), acute ischemic stroke (11%) and acute rheumatic disorders (3%). The mean and median ages were 76.4 and 77 years, respectively, with 68% of patients ≥ 75 years of age, 97% were severely immobilized at study entry, and 62% had D-dimer ≥ 2 × ULN.
While the APEX Study was ongoing (after 35% enrollment), the study was amended to ensure enrollment of patients ≥ 75 years of age or with D-dimer values ≥ 2 × ULN. The APEX trial excluded patients whose condition required prolonged anticoagulation (e.g., concurrent VTE, atrial fibrillation, cardiac valve prosthesis), were at increased risk of bleeding, had liver dysfunction, were on dual antiplatelet therapy, or patients who had both severe renal insufficiency (CrCl 15-29 ml/min) and required the concomitant use of a P-gp inhibitor.
The efficacy of BEVYXXA was based upon the composite outcome of the occurrence of any of the following events up to Day 35 visit:
- Asymptomatic proximal Deep Vein Thrombosis (DVT) (detected by ultrasound),
- Symptomatic proximal or distal DVT,
- Non-fatal Pulmonary Embolism (PE), or
- VTE-related death.
Efficacy analyses were performed based on the modified Intent-to-Treat (mITT) population. The mITT population consisted of all patients who had taken at least one dose of study drug and who had follow-up assessment data on one or more primary or secondary efficacy outcome components. A total of 7,441 patients (N=3,721 for BEVYXXA and N=3,720 for enoxaparin) were included in the mITT population.
The efficacy results for the APEX trial are provided in Table 5 below.

For patients with D-dimer ≥ 2 ULN at baseline, the event rate is 5.7% in the BEVYXXA arm vs. 7.2% in the enoxaparin arm (relative risk = 0.79, 95% CI [0.63, 0.98]).
For patients with D-dimer ≥ 2 ULN at baseline or age ≥ 75 years, the event rate is 4.7% in the BEVYXXA arm vs. 6.0% in the enoxaparin arm (relative risk = 0.78, 95% CI [0.64, 0.96]).
Results for the primary efficacy analysis for subjects that were stratified at randomization to the 80 mg BEVYXXA dose group in the mITT population are shown in Table 6 below.
Patients who were randomized to receive 40 mg BEVYXXA (those with severe renal impairment or receiving P-gp inhibitors), had VTE rates similar to the enoxaparin arm (6 to 14 days followed by placebo) shown in Table 7 below.
