药品介绍

达比加群酯(商品名为Pradaxa)由德国勃林格殷格翰公司开，于2008年4月在德国和英国率先上市，为近期成功开发的具有多种特点的新型抗凝血药物。 

深静脉血栓形成和肺动脉栓塞是人工关节置换术后常见的并发症，严重者甚至可危及患者生命，为此术后需常规使用抗凝血药物。达比加群酯为近期成功开发的具有多种特点的新型抗凝血药物。 

达比加群酯(商品名为Pradaxa)由德国勃林格殷格翰公司开，于2008年4月在德国和英国率先上市，这是继华法林之后50年来上市的首个新类别口服抗凝血药物。本品的上市，是抗凝血治疗领域和潜在致死性血栓预防领域的一项重大进展，具有里程碑意义。 

达比加群酯是一种新型的合成的直接凝血酶抑制剂，是dabigatran的前体药物，属非肽类的凝血酶抑制剂。口服经胃肠吸收后，在体内转化为具有直接抗凝血活性的dabigatran。
dabigatran结合于凝血酶的纤维蛋白特异结合位点，阻止纤维蛋白原裂解为纤维蛋白，从而阻断了凝血瀑布网络的最后步骤及血栓形成。dabigatran可以从纤维蛋白一凝血酶结合体上解离，发挥可逆的抗凝作用。 

达比加群酯口服用药后经胃肠道迅速吸收，用药后1h起效，2～3h即达血浆峰浓度，如果与食物同服，其血浆达峰时间后移。达比加群酯口服生物利用度较低，仅6．5%，dabigatran血浆蛋白结合率为25%～30%。药物的平均终末清除半衰期为15h，约80%以原形形式经肾脏排除，其余以葡萄糖醛酸结合以胆汁分泌形式排除体外。肾功能不全(肌酐清除率<50ml／min>可延长其血浆清除时间，并使血浆药物浓度升高。dabigatran的清除不依赖于肝脏细胞色素p450系统，而且不影响从肝脏CYP2C9及CYP3A4酶系统代谢的药物的活性。dabigatran的抗凝强度与血浆浓度成正比，同时服用阿司匹林或其他血小板抑制剂，可增加其出血危险。 

达比加群酯是直接凝血酶抑制剂，具有可以口服、强效、无需特殊用药监测、药物相互作用少等特点。体外、体内试验和临床各项研究均提示本品具有良好的疗效及药动学特性，临床应用前景乐观，其成功上市是抗凝血药物研究领域的一项重大突破 

**深静脉血栓形成和肺动脉栓塞是人工关节置换术后常见的并发症，严重者甚至可危及患者生命，为此术后需常规使用抗凝血药物。达比加群酯为近期成功开发的具有多种特点的新型抗凝血药物。由德国勃林格殷格翰公司开发的达比加群酯(商品名为Pradaxa)于2008年4月在德国和英国率先上市，这是继华法林之后50年来上市的首个新类别口服抗凝血药物。本品的上市，是抗凝血治疗领域和潜在致死性血栓预防领域的一项重大进展，具有里程碑意义。 

【药理作用】 
凝血酶是细胞外胰岛素样丝氨酸蛋白酶，在凝血过程中具有重要作用，一方面，其能使纤维蛋白原裂解成为纤维蛋白，后者参与构成不溶性血栓基质；另一方面，其能诱导血小板活化和聚集，进而引发一系列次级凝血级联反应。达比加群酯为前药，在体内转化为有活性的达比加群，后者通过直接抑制凝血酶而发挥抗凝血效应。体外，达比加群能有效抑制人凝血酶活性[半数抑制浓度(ICs0)为9.3nmol／L]，其对凝血酶的选择性[抑制常数(kl)为(4.5±0.2)nmol／L]高于凝血因子Xa[Ki为(3760±20)nmol／L]、胰蛋白酶[Kl为(50.3±0.3)nmol／L]、纤维蛋白溶酶[K『为(1695±5O)nmol／L]和激活蛋白C[为(20930±1O)nmol／L]等。 

【动物实验】 
小鼠静脉血栓形成模型试验嘲显示，达比加群酯抑制血栓形成作用呈剂量和时间依赖性。小鼠麻醉前30分钟服用达比加群酯，能获得最大的抑制血栓形成效应。试验还提示，达比加群酯低剂量组麻醉前2小时给药，也能抑制血栓形成；而高剂量组，即使麻醉前3小时给药仍能显著抑制血栓形成。达比加群酯口服对活化部分凝血活酶时间(aPTT)作用呈剂量和时间依赖性，这种依赖性高剂量组表现尤为明显，剂量越高、给药时间距离麻醉时间越短、aPTT越长。 

【临床研究】 
2004年11月一2006年3月，在欧洲、澳洲和南非105个研究中心进行的随机双盲RE.MODEL研究，2076例行单侧全膝关节置换术的患者随机分入达比加群酯各剂量组[150mg组(一日1次口服150mg)、220mg组(一日1次口服220mg)]或依诺肝素组(一日1次皮下注射40mg)。达比加群酯各剂量组于术后1-4小时开始服药，依诺肝素组于术前一日晚间开始用药，疗程均为6—10日，随访期为3个月。主要疗效评价终点为总VTE(包括血管造影和症状性VTE)发生率及死亡率的复合终点，安全性评价终点为出血事件发生率。 
研究最终对1541例患者的临床数据进行了有效性分析，结果表明：达比加群酯疗效与依诺肝素无显著差异，150mg组、220mg组和依诺肝素组达到主要疗效评价终点的患者比例分别为40.5％(213例，526例)、36.4％(183例／503例)和37.7％(193例／512例)，其中220mg组稍低于其他两组；在预防症状性深静脉血栓形成方面，达比加群酯150mg组和220mg组均优于依诺肝素组，三组深静脉血栓形成的发生率分别为0.4％(3例／696例)、0.1％(1例，675例)和1.2％(8例，685例)。安全性方面，达比加群酯各组出血发生率与依诺肝素组相比无显著差异，三组分别为1.3％(9例／703例)、1.5％(10例/679例)和1.3％(9例/694例)，三组均未出现因大出血死亡的病例。三组因不良反应导致治疗终止的发生率无显著差异，分别为3_7％、3.7％和4.6％。提示在预防全膝关节置换术后VTE发生方面，达比加群酯至少与依诺肝素疗效同等、安全性类似。 

【不良反应】 
与其他各种抗凝药物类似，达比加群酯用于抗凝治疗过程中也不可避免会出现出血现象。尤其在高剂量应用时，出血发生率更高。Eriksson等率先报道的达比加群酯剂量递增安全性研究即BISTROI研究，314例受试者术后4—8小时开始口服达比加群酯一日2次，每次12.5、25、50、100、150、200和300mg或一日1次150、300mg，结果表明，各组均未见大出血事件，但最高剂量组(一日2次，每次300mg)在接受治疗初始几日内20例受试者中就有2例出现多部位出血。小出血事件的发生具有明显的剂量相关性。其他不良反应，达比加群酯与依诺肝素相比无显著差异。 
推荐剂量(150或220mg)下，达比加群酯严重不良反应发生率均为8％。总不良反应发生率均为77％，因严重不良反应导致治疗终止的发生率分别为8％和6％。恶心和呕吐发生率分别为21％-22％和16％-17％；11％-13％的患者出现便秘和发热；6％-7％的患者出现低血压、失眠和水肿；1％-4％的患者出现贫血、眩晕、腹泻、疱疹、头痛，尿潴留、继发性血肿、消化不良和心动过速等症状。 
目前，达比加群酯适应证仅为关节置换术后血栓形成的预防，其他适应证包括心房颤动、急性冠状动脉综合征、急性症状性静脉血栓形成和缺血陛脑卒中等，尚处于临床研究中。 
总之，达比加群酯是直接凝血酶抑制剂，具有可以口服、强效、无需特殊用药监测、药物相互作用少等特点。体外、体内试验和临床各项研究均提示达比加群酯具有良好的疗效及药动学特性，临床应用前景乐观，其成功上市是抗凝血药物研究领域的一项重大突破。 

**FDA批准Pradaxa预防心房颤动患者中风 
2010年10月19日，美国食品药品管理局（FDA）批准Pradaxa胶囊（达比加群酯）用于预防心节律异常（心房颤动）患者中风和血栓的发生。心房颤动是最常见的一种心节律异常，包括心房快速律动和不规则律动。目前在美国患此病的患者超过2,000,000人。 
Pradaxa是一种抗凝剂，通过抑制血液中起凝血作用的凝血酶而发挥作用。Pradaxa的安全性和有效性已经一项临床试验得以证实，该试验将Pradaxa与抗凝剂华法林进行了对比和比较。在试验中，与使用华法林的患者相比，使用Pradaxa的患者较少出现中风。 
Pradaxa常见的不良反应是出血，包括危及生命的和致死性的出血。另外还有一些胃肠道症状，包括胃部不适（消化不良）、胃痛、恶心、胃灼热、胃气胀。Pradaxa的获批伴随着一项用药指南，目的是使患者知悉使用此药存在出现严重出血的可能性..

 

Generic Name: dabigatran etexilate mesylate
Dosage Form: capsule

 

WARNING: (A) PREMATURE DISCONTINUATION OF Pradaxa INCREASES THE RISK OF THROMBOTIC EVENTS, and (B) SPINAL/EPIDURAL HEMATOMA

(A) PREMATURE DISCONTINUATION OF Pradaxa INCREASES THE RISK OF THROMBOTIC EVENTS
Premature discontinuation of any oral anticoagulant, including Pradaxa, increases the risk of thrombotic events. If anticoagulation with Pradaxa is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant [see Dosage and Administration (2.4, 2.5, 2.6) and Warnings and Precautions (5.1)].

(B) SPINAL/EPIDURAL HEMATOMA
Epidural or spinal hematomas may occur in patients treated with Pradaxa who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:

 • use of indwelling epidural catheters
 • concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants
 • a history of traumatic or repeated epidural or spinal punctures
 • a history of spinal deformity or spinal surgery
 • optimal timing between the administration of Pradaxa and neuraxial procedures is not known [see Warnings and Precautions (5.3)].

Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary [see Warnings and Precautions (5.3)].

Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated [see Warnings and Precautions (5.3)].

 

 

 

Pradaxa is indicated to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation.

Pradaxa is indicated for the treatment of deep venous thrombosis and pulmonary embolism in patients who have been treated with a parenteral anticoagulant for 5-10 days.

Pradaxa is indicated to reduce the risk of recurrence of deep venous thrombosis and pulmonary embolism in patients who have been previously treated.

Pradaxa is indicated for the prophylaxis of deep vein thrombosis and pulmonary embolism, in patients who have undergone hip replacement surgery.

Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation

For patients with creatinine clearance (CrCl) >30 mL/min, the recommended dose of Pradaxa is 150 mg taken orally, twice daily. For patients with severe renal impairment (CrCl 15-30 mL/min), the recommended dose of Pradaxa is 75 mg twice daily [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. Dosing recommendations for patients with a CrCl <15 mL/min or on dialysis cannot be provided.

Treatment of Deep Venous Thrombosis and Pulmonary Embolism

For patients with CrCl >30 mL/min, the recommended dose of Pradaxa is 150 mg taken orally, twice daily, after 5-10 days of parenteral anticoagulation. Dosing recommendations for patients with a CrCl ≤30 mL/min or on dialysis cannot be provided [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism

For patients with CrCl >30 mL/min, the recommended dose of Pradaxa is 150 mg taken orally, twice daily after previous treatment. Dosing recommendations for patients with a CrCl ≤30 mL/min or on dialysis cannot be provided [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery

For patients with CrCl >30 mL/min, the recommended dose of Pradaxa is 110 mg taken orally 1-4 hours after surgery and after hemostasis has been achieved, then 220 mg taken once daily for 28-35 days. If Pradaxa is not started on the day of surgery, after hemostasis has been achieved initiate treatment with 220 mg once daily. Dosing recommendations for patients with a CrCl ≤30 mL/min or on dialysis cannot be provided [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.2, 12.3)].

Assess renal function prior to initiation of treatment with Pradaxa. Periodically assess renal function as clinically indicated (i.e., more frequently in clinical situations that may be associated with a decline in renal function) and adjust therapy accordingly. Discontinue Pradaxa in patients who develop acute renal failure while on Pradaxa and consider alternative anticoagulant therapy.

Generally, the extent of anticoagulation does not need to be assessed. When necessary, use aPTT or ECT, and not INR, to assess for anticoagulant activity in patients on Pradaxa [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2)].

Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation

In patients with moderate renal impairment (CrCl 30-50 mL/min), concomitant use of the P-gp inhibitor dronedarone or systemic ketoconazole can be expected to produce dabigatran exposure similar to that observed in severe renal impairment. Reduce the dose of Pradaxa to 75 mg twice daily [see Warnings and Precautions (5.5), Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

Treatment and Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism

Dosing recommendations for patients with CrCl ≤30 mL/min cannot be provided. Avoid use of concomitant P-gp inhibitors in patients with CrCl <50 mL/min [see Warnings and Precautions (5.5), Drug Interactions (7.2) and Clinical Pharmacology (12.3)].

Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery

Dosing recommendations for patients with CrCl ≤30 mL/min or on dialysis cannot be provided. Avoid use of concomitant P-gp inhibitors in patients with CrCl <50 mL/min [see Warnings and Precautions (5.5), Drug Interactions (7.3) and Clinical Pharmacology (12.2, 12.3)].

Instruct patients to swallow the capsules whole. Pradaxa should be taken with a full glass of water. Breaking, chewing, or emptying the contents of the capsule can result in increased exposure [see Clinical Pharmacology (12.3)].

If a dose of Pradaxa is not taken at the scheduled time, the dose should be taken as soon as possible on the same day; the missed dose should be skipped if it cannot be taken at least 6 hours before the next scheduled dose. The dose of Pradaxa should not be doubled to make up for a missed dose.

When converting patients from warfarin therapy to Pradaxa, discontinue warfarin and start Pradaxa when the INR is below 2.0.

When converting from Pradaxa to warfarin, adjust the starting time of warfarin based on creatinine clearance as follows:

· For CrCl ≥50 mL/min, start warfarin 3 days before discontinuing Pradaxa.

· For CrCl 30-50 mL/min, start warfarin 2 days before discontinuing Pradaxa.

· For CrCl 15-30 mL/min, start warfarin 1 day before discontinuing Pradaxa.

· For CrCl <15 mL/min, no recommendations can be made.

Because Pradaxa can increase INR, the INR will better reflect warfarin’s effect only after Pradaxa has been stopped for at least 2 days [see Clinical Pharmacology (12.2)].

For patients currently receiving a parenteral anticoagulant, start Pradaxa 0 to 2 hours before the time that the next dose of the parenteral drug was to have been administered or at the time of discontinuation of a continuously administered parenteral drug (e.g., intravenous unfractionated heparin).

For patients currently taking Pradaxa, wait 12 hours (CrCl ≥30 mL/min) or 24 hours (CrCl <30 mL/min) after the last dose of Pradaxa before initiating treatment with a parenteral anticoagulant [see Clinical Pharmacology (12.3)].

If possible, discontinue Pradaxa 1 to 2 days (CrCl ≥50 mL/min) or 3 to 5 days (CrCl <50 mL/min) before invasive or surgical procedures because of the increased risk of bleeding. Consider longer times for patients undergoing major surgery, spinal puncture, or placement of a spinal or epidural catheter or port, in whom complete hemostasis may be required [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

If surgery cannot be delayed, there is an increased risk of bleeding [see Warnings and Precautions (5.2)]. This risk of bleeding should be weighed against the urgency of intervention [see Warnings and Precautions (5.1, 5.3)]. Use a specific reversal agent (idarucizumab) in case of emergency surgery or urgent procedures when reversal of the anticoagulant effect of dabigatran is needed. Refer to the idarucizumab prescribing information for additional information. Restart Pradaxa as soon as medically appropriate.

Pradaxa is contraindicated in patients with:

· Active pathological bleeding [see Warnings and Precautions (5.2) and Adverse Reactions (6.1)].

· History of a serious hypersensitivity reaction to Pradaxa (e.g., anaphylactic reaction or anaphylactic shock) [see Adverse Reactions (6.1)].

· Mechanical prosthetic heart valve [see Warnings and Precautions (5.4)].

Premature discontinuation of any oral anticoagulant, including Pradaxa, in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. If Pradaxa is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant and restart Pradaxa as soon as medically appropriate [see Dosage and Administration (2.4, 2.5, 2.6)].

Pradaxa increases the risk of bleeding and can cause significant and, sometimes, fatal bleeding. Promptly evaluate any signs or symptoms of blood loss (e.g., a drop in hemoglobin and/or hematocrit or hypotension). Discontinue Pradaxa in patients with active pathological bleeding [see Dosage and Administration (2.2)].

 

 

Risk factors for bleeding include the concomitant use of other drugs that increase the risk of bleeding (e.g., anti-platelet agents, heparin, fibrinolytic therapy, and chronic use of NSAIDs). Pradaxa’s anticoagulant activity and half-life are increased in patients with renal impairment [see Clinical Pharmacology (12.2)].

Reversal of Anticoagulant Effect:

A specific reversal agent (idarucizumab) for dabigatran is available when reversal of the anticoagulant effect of dabigatran is needed:

· For emergency surgery/urgent procedures

· In life-threatening or uncontrolled bleeding

Hemodialysis can remove dabigatran; however the clinical experience supporting the use of hemodialysis as a treatment for bleeding is limited [see Overdosage (10)]. Prothrombin complex concentrates, or recombinant Factor VIIa may be considered but their use has not been evaluated in clinical trials. Protamine sulfate and vitamin K are not expected to affect the anticoagulant activity of dabigatran. Consider administration of platelet concentrates in cases where thrombocytopenia is present or long-acting antiplatelet drugs have been used.

When neuraxial anesthesia (spinal/epidural anesthesia) or spinal puncture is employed, patients treated with anticoagulant agents are at risk of developing an epidural or spinal hematoma which can result in long-term or permanent paralysis [see Boxed Warning].

To reduce the potential risk of bleeding associated with the concurrent use of dabigatran and epidural or spinal anesthesia/analgesia or spinal puncture, consider the pharmacokinetic profile of dabigatran [see Clinical Pharmacology (12.3)]. Placement or removal of an epidural catheter or lumbar puncture is best performed when the anticoagulant effect of dabigatran is low; however, the exact timing to reach a sufficiently low anticoagulant effect in each patient is not known.

Should the physician decide to administer anticoagulation in the context of epidural or spinal anesthesia/analgesia or lumbar puncture, monitor frequently to detect any signs or symptoms of neurological impairment, such as midline back pain, sensory and motor deficits (numbness, tingling, or weakness in lower limbs), bowel and/or bladder dysfunction. Instruct patients to immediately report if they experience any of the above signs or symptoms. If signs or symptoms of spinal hematoma are suspected, initiate urgent diagnosis and treatment including consideration for spinal cord decompression even though such treatment may not prevent or reverse neurological sequelae.

The safety and efficacy of Pradaxa in patients with bileaflet mechanical prosthetic heart valves was evaluated in the RE-ALIGN trial, in which patients with bileaflet mechanical prosthetic heart valves (recently implanted or implanted more than three months prior to enrollment) were randomized to dose adjusted warfarin or 150, 220, or 300 mg of Pradaxa twice a day. RE-ALIGN was terminated early due to the occurrence of significantly more thromboembolic events (valve thrombosis, stroke, transient ischemic attack, and myocardial infarction) and an excess of major bleeding (predominantly post-operative pericardial effusions requiring intervention for hemodynamic compromise) in the Pradaxa treatment arm as compared to the warfarin treatment arm. These bleeding and thromboembolic events were seen both in patients who were initiated on Pradaxa post-operatively within three days of mechanical bileaflet valve implantation, as well as in patients whose valves had been implanted more than three months prior to enrollment. Therefore, the use of Pradaxa is contraindicated in patients with mechanical prosthetic valves [see Contraindications (4)].

The use of Pradaxa for the prophylaxis of thromboembolic events in patients with atrial fibrillation in the setting of other forms of valvular heart disease, including the presence of a bioprosthetic heart valve, has not been studied and is not recommended.

The concomitant use of Pradaxa with P-gp inducers (e.g., rifampin) reduces exposure to dabigatran and should generally be avoided [see Clinical Pharmacology (12.3)].

P-gp inhibition and impaired renal function are the major independent factors that result in increased exposure to dabigatran [see Clinical Pharmacology (12.3)]. Concomitant use of P-gp inhibitors in patients with renal impairment is expected to produce increased exposure of dabigatran compared to that seen with either factor alone.

Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation

Reduce the dose of Pradaxa to 75 mg twice daily when dronedarone or systemic ketoconazole is coadministered with Pradaxa in patients with moderate renal impairment (CrCl 30-50 mL/min). Avoid use of Pradaxa and P-gp inhibitors in patients with severe renal impairment (CrCl 15-30 mL/min) [see Drug Interactions (7.1) and Use in Specific Populations (8.6)].

Treatment and Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism

Avoid use of Pradaxa and concomitant P-gp inhibitors in patients with CrCl <50 mL/min [see Drug Interactions (7.2) and Use in Specific Populations (8.6)].

Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery

Avoid use of Pradaxa and concomitant P-gp inhibitors in patients with CrCl <50 mL/min [see Drug Interactions (7.3) and Use in Specific Populations (8.6)].

The following serious adverse reactions are described elsewhere in the labeling:

· Increased Risk of Thrombotic Events after Premature Discontinuation [see Warnings and Precautions (5.1)]

· Risk of Bleeding [see Warnings and Precautions (5.2)]

· Spinal/Epidural Anesthesia or Puncture [see Warnings and Precautions (5.3)]

· Thromboembolic and Bleeding Events in Patients with Prosthetic Heart Valves [see Warnings and Precautions (5.4)]

The most serious adverse reactions reported with Pradaxa were related to bleeding [see Warnings and Precautions (5.2)].

Because clinical trials are conducted under widely varying conditions, adverse reactions 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.

Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation

The RE-LY (Randomized Evaluation of Long-term Anticoagulant Therapy) study provided safety information on the use of two doses of Pradaxa and warfarin [see Clinical Studies (14.1)]. The numbers of patients and their exposures are described in Table 1. Limited information is presented on the 110 mg dosing arm because this dose is not approved.

Table 1 Summary of Treatment Exposure in RE-LY
		Pradaxa 110 mg twice daily	Pradaxa 150 mg twice daily	Warfarin
Total number treated		5983	6059	5998
Exposure
	> 12 months	4936	4939	5193
	> 24 months	2387	2405	2470
Mean exposure (months)		20.5	20.3	21.3
Total patient-years		10,242	10,261	10,659

Drug Discontinuation in RE-LY

The rates of adverse reactions leading to treatment discontinuation were 21% for Pradaxa 150 mg and 16% for warfarin. The most frequent adverse reactions leading to discontinuation of Pradaxa were bleeding and gastrointestinal events (i.e., dyspepsia, nausea, upper abdominal pain, gastrointestinal hemorrhage, and diarrhea).

Bleeding [see Warnings and Precautions (5.2)]

Table 2 shows the number of adjudicated major bleeding events during the treatment period in the RE-LY study, with the bleeding rate per 100 subject-years (%). Major bleeding is defined as bleeding accompanied by one or more of the following: a decrease in hemoglobin of ≥2 g/dL, a transfusion of ≥2 units of packed red blood cells, bleeding at a critical site or with a fatal outcome. Intracranial hemorrhage included intracerebral (hemorrhagic stroke), subarachnoid, and subdural bleeds.

 

 

 

Table 2 Adjudicated Major Bleeding Events in Treated Patientsa
aPatients during treatment or within 2 days of stopping study treatment. Major bleeding events within each subcategory were counted once per patient, but patients may have contributed events to multiple subcategories. bAnnual event rate per 100 pt-years = 100 * number of subjects with event/subject-years. Subject-years is defined as cumulative number of days from first drug intake to event date, date of last drug intake + 2, death date (whatever occurred first) across all treated subjects divided by 365.25. In case of recurrent events of the same category, the first event was considered. cDefined as bleeding accompanied by one or more of the following: a decrease in hemoglobin of ≥2 g/dL, a transfusion of 2 or more units of packed red blood cells, bleeding at a critical site or with fatal outcome. dIntracranial bleed included intracerebral (hemorrhagic stroke), subarachnoid, and subdural bleeds. eOn-treatment analysis based on the safety population, compared to ITT analysis presented in Section 14 Clinical Studies. fFatal bleed: Adjudicated major bleed as defined above with investigator reported fatal outcome and adjudicated death with primary cause from bleeding. gNon-intracranial fatal bleed: Adjudicated major bleed as defined above and adjudicated death with primary cause from bleeding but without symptomatic intracranial bleed based on investigator’s clinical assessment.

There was a higher rate of any gastrointestinal bleeds in patients receiving Pradaxa 150 mg than in patients receiving warfarin (6.6% vs. 4.2%, respectively).

The risk of major bleeds was similar with Pradaxa 150 mg and warfarin across major subgroups defined by baseline characteristics (see Figure 1), with the exception of age, where there was a trend towards a higher incidence of major bleeding on Pradaxa (hazard ratio 1.2, 95% CI: 1.0 to 1.5) for patients ≥75 years of age.

Note: The figure above presents effects in various subgroups all of which are baseline characteristics and all of which were pre-specified. The 95% confidence limits that are shown do not take into account how many comparisons were made, nor do they reflect the effect of a particular factor after adjustment for all other factors. Apparent homogeneity or heterogeneity among groups should not be over-interpreted.

Gastrointestinal Adverse Reactions

Patients on Pradaxa 150 mg had an increased incidence of gastrointestinal adverse reactions (35% vs. 24% on warfarin). These were commonly dyspepsia (including abdominal pain upper, abdominal pain, abdominal discomfort, and epigastric discomfort) and gastritis-like symptoms (including GERD, esophagitis, erosive gastritis, gastric hemorrhage, hemorrhagic gastritis, hemorrhagic erosive gastritis, and gastrointestinal ulcer).

Hypersensitivity Reactions

In the RE-LY study, drug hypersensitivity (including urticaria, rash, and pruritus), allergic edema, anaphylactic reaction, and anaphylactic shock were reported in <0.1% of patients receiving Pradaxa.

Treatment and Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism

Pradaxa was studied in 4387 patients in 4 pivotal, parallel, randomized, double-blind trials. Three of these trials were active-controlled (warfarin) (RE-COVER, RE-COVER II, and RE-MEDY), and one study (RE-SONATE) was placebo-controlled. The demographic characteristics were similar among the 4 pivotal studies and between the treatment groups within these studies. Approximately 60% of the treated patients were male, with a mean age of 55.1 years. The majority of the patients were white (87.7%), 10.3% were Asian, and 1.9% were black with a mean CrCl of 105.6 mL/min.

Bleeding events for the 4 pivotal studies were classified as major bleeding events if at least one of the following criteria applied: fatal bleeding, symptomatic bleeding in a critical area or organ (intraocular, intracranial, intraspinal or intramuscular with compartment syndrome, retroperitoneal bleeding, intra-articular bleeding, or pericardial bleeding), bleeding causing a fall in hemoglobin level of 2.0 g/dL (1.24 mmol/L or more, or leading to transfusion of 2 or more units of whole blood or red cells).

RE-COVER and RE-COVER II studies compared Pradaxa 150 mg twice daily and warfarin for the treatment of deep vein thrombosis and pulmonary embolism. Patients received 5-10 days of an approved parenteral anticoagulant therapy followed by 6 months, with mean exposure of 164 days, of oral only treatment; warfarin was overlapped with parenteral therapy. Table 3 shows the number of patients experiencing bleeding events in the pooled analysis of RE-COVER and RE-COVER II studies during the full treatment including parenteral and oral only treatment periods after randomization.

The rate of any gastrointestinal bleeds in patients receiving Pradaxa 150 mg in the full treatment period was 3.1% (2.4% on warfarin).

The RE-MEDY and RE-SONATE studies provided safety information on the use of Pradaxa for the reduction in the risk of recurrence of deep vein thrombosis and pulmonary embolism.

RE-MEDY was an active-controlled study (warfarin) in which 1430 patients received Pradaxa 150 mg twice daily following 3 to 12 months of oral anticoagulant regimen. Patients in the treatment studies who rolled over into the RE-MEDY study had a combined treatment duration of up to more than 3 years, with mean exposure of 473 days. Table 4 shows the number of patients experiencing bleeding events in the study.

In the RE-MEDY study, the rate of any gastrointestinal bleeds in patients receiving Pradaxa 150 mg was 3.1% (2.2% on warfarin).

 

 

 

RE-SONATE was a placebo-controlled study in which 684 patients received Pradaxa 150 mg twice daily following 6 to 18 months of oral anticoagulant regimen. Patients in the treatment studies who rolled over into the RE-SONATE study had combined treatment duration up to 9 months, with mean exposure of 165 days. Table 5 shows the number of patients experiencing bleeding events in the study.

In the RE-SONATE study, the rate of any gastrointestinal bleeds in patients receiving Pradaxa 150 mg was 0.7% (0.3% on placebo).

Clinical Myocardial Infarction Events
In the active-controlled VTE studies, a higher rate of clinical myocardial infarction was reported in patients who received Pradaxa [20 (0.66 per 100 patient-years)] than in those who received warfarin [5 (0.17 per 100 patient-years)]. In the placebo-controlled study, a similar rate of non-fatal and fatal clinical myocardial infarction was reported in patients who received Pradaxa [1 (0.32 per 100 patient-years)] and in those who received placebo [1 (0.34 per 100 patient-years)].

Gastrointestinal Adverse Reactions
In the four pivotal studies, patients on Pradaxa 150 mg had a similar incidence of gastrointestinal adverse reactions (24.7% vs. 22.7% on warfarin). Dyspepsia (including abdominal pain upper, abdominal pain, abdominal discomfort, and epigastric discomfort) occurred in patients on Pradaxa in 7.5% vs. 5.5% on warfarin, and gastritis-like symptoms (including gastritis, GERD, esophagitis, erosive gastritis and gastric hemorrhage) occurred at 3.0% vs. 1.7%, respectively.

Hypersensitivity Reactions
In the 4 pivotal studies, drug hypersensitivity (including urticaria, rash, and pruritus), allergic edema, anaphylactic reaction, and anaphylactic shock were reported in 0.1% of patients receiving Pradaxa.

Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery
Pradaxa was studied in 5476 patients, randomized and treated in two double-blind, active-controlled non-inferiority trials (RE-NOVATE and RE-NOVATE II). The demographic characteristics were similar across the two studies and between the treatment groups within these studies. Approximately 45.3 % of the treated patients were male, with a mean age of 63.2 years. The majority of the patients were white (96.1%), 3.6% were Asian, and 0.3% were black with a mean CrCl of 92 mL/min.

Bleeding events for the RE-NOVATE and RE-NOVATE II studies were classified as major bleeding events if at least one of the following criteria applied: fatal bleeding, symptomatic bleeding in a critical area or organ (intraocular, intracranial, intraspinal or retroperitoneal bleeding), bleeding causing a fall in hemoglobin level of 2.0 g/dL (1.24 mmol/L) or more, or leading to transfusion of 2 or more units of whole blood or red cells, requiring treatment cessation or leading to re-operation.

The RE-NOVATE study compared Pradaxa 75 mg taken orally 1-4 hours after surgery followed by 150 mg once daily, Pradaxa 110 mg taken orally 1-4 hours after surgery followed by 220 mg once daily and subcutaneous enoxaparin 40 mg once daily initiated the evening before surgery for the prophylaxis of deep vein thrombosis and pulmonary embolism in patients who had undergone hip replacement surgery. The RE-NOVATE II study compared Pradaxa 110 mg taken orally 1-4 hours after surgery followed by 220 mg once daily and subcutaneous enoxaparin 40 mg once daily initiated the evening before surgery for the prophylaxis of deep vein thrombosis and pulmonary embolism in patients who had undergone hip replacement surgery. In the RE-NOVATE and RE-NOVATE II studies, patients received 28-35 days of Pradaxa or enoxaparin with median exposure of 33 days. Tables 6 and 7 show the number of patients experiencing bleeding events in the analysis of RE-NOVATE and RE-NOVATE II.

Table 6 Bleeding Events in RE-NOVATE Treated Patients
	Pradaxa 220 mg N (%)	Enoxaparin N (%)
Patients	N=1146	N=1154
Major bleeding event	23 (2.0)	18 (1.6)

In the two studies, the rate of major gastrointestinal bleeds in patients receiving Pradaxa and enoxaparin was the same (0.1%) and for any gastrointestinal bleeds was 1.4% for Pradaxa 220 mg and 0.9% for enoxaparin.

Gastrointestinal Adverse Reactions
In the two studies, the incidence of gastrointestinal adverse reactions for patients on Pradaxa 220 mg and enoxaparin was 39.5% and 39.5%, respectively. Dyspepsia (including abdominal pain upper, abdominal pain, abdominal discomfort, and epigastric discomfort) occurred in patients on Pradaxa 220 mg in 4.1% vs. 3.8% on enoxaparin, and gastritis-like symptoms (including gastritis, GERD, esophagitis, erosive gastritis and gastric hemorrhage) occurred at 0.6% vs. 1.0%, respectively.

Hypersensitivity Reactions
In the two studies, drug hypersensitivity (such as urticaria, rash, and pruritus) was reported in 0.3% of patients receiving Pradaxa 220 mg.

 

 

 

Clinical Myocardial Infarction Events
In the two studies, clinical myocardial infarction was reported in 2 (0.1%) of patients who received Pradaxa 220 mg and 6 (0.3%) of patients who received enoxaparin.

The following adverse reactions have been identified during post approval use of Pradaxa. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following adverse reactions have been identified during post approval use of Pradaxa: angioedema, thrombocytopenia, esophageal ulcer.

The concomitant use of Pradaxa with P-gp inducers (e.g., rifampin) reduces exposure to dabigatran and should generally be avoided [see Clinical Pharmacology (12.3)].

P-gp inhibition and impaired renal function are the major independent factors that result in increased exposure to dabigatran [see Clinical Pharmacology (12.3)]. Concomitant use of P-gp inhibitors in patients with renal impairment is expected to produce increased exposure of dabigatran compared to that seen with either factor alone.

In patients with moderate renal impairment (CrCl 30-50 mL/min), reduce the dose of Pradaxa to 75 mg twice daily when administered concomitantly with the P-gp inhibitors dronedarone or systemic ketoconazole. The use of the P-gp inhibitors verapamil, amiodarone, quinidine, clarithromycin, and ticagrelor does not require a dose adjustment of Pradaxa. These results should not be extrapolated to other P-gp inhibitors [see Warnings and Precautions (5.5), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)].

The concomitant use of Pradaxa and P-gp inhibitors in patients with severe renal impairment (CrCl 15-30 mL/min) should be avoided [see Warnings and Precautions (5.5), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)].

Avoid use of Pradaxa and P-gp inhibitors in patients with CrCl <50 mL/min [see Warnings and Precautions (5.5), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)].

In patients with CrCl ≥50 mL/min who have concomitant administration of P-gp inhibitors such as dronedarone or systemic ketoconazole, it may be helpful to separate the timing of administration of dabigatran and the P-gp inhibitor by several hours. The concomitant use of Pradaxa and P-gp inhibitors in patients with CrCl <50 mL/min should be avoided [see Warnings and Precautions (5.5), Use in Specific Populations (8.6) and Clinical Pharmacology (12.2, 12.3)].

Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women.

Dabigatran has been shown to decrease the number of implantations when male and female rats were treated at a dosage of 70 mg/kg (about 2.6 to 3.0 times the human exposure at maximum recommended human dose [MRHD] of 300 mg/day based on area under the curve [AUC] comparisons) prior to mating and up to implantation (gestation Day 6). Treatment of pregnant rats after implantation with dabigatran at the same dose increased the number of dead offspring and caused excess vaginal/uterine bleeding close to parturition. Although dabigatran increased the incidence of delayed or irregular ossification of fetal skull bones and vertebrae in the rat, it did not induce major malformations in rats or rabbits.

Safety and effectiveness of Pradaxa during labor and delivery have not been studied in clinical trials. Consider the risks of bleeding and of stroke in using Pradaxa in this setting [see Warnings and Precautions (5.2)].

Death of offspring and mother rats during labor in association with uterine bleeding occurred during treatment of pregnant rats from implantation (gestation Day 7) to weaning (lactation Day 21) with dabigatran at a dose of 70 mg/kg (about 2.6 times the human exposure at MRHD of 300 mg/day based on AUC comparisons).

 

 

 

 

It is not known whether dabigatran is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Pradaxa, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Safety and effectiveness of Pradaxa in pediatric patients have not been established.

Of the total number of patients in the RE-LY study, 82% were 65 and over, while 40% were 75 and over. The risk of stroke and bleeding increases with age, but the risk-benefit profile is favorable in all age groups [see Warnings and Precautions (5), Adverse Reactions (6.1), and Clinical Studies (14.1)].

Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation

No dose adjustment of Pradaxa is recommended in patients with mild or moderate renal impairment [see Clinical Pharmacology (12.3)]. Reduce the dose of Pradaxa in patients with severe renal impairment (CrCl 15-30 mL/min) [see Dosage and Administration (2.1, 2.2) and Clinical Pharmacology (12.3)]. Dosing recommendations for patients with CrCl <15 mL/min or on dialysis cannot be provided.

Adjust dose appropriately in patients with renal impairment receiving concomitant P-gp inhibitors [see Warnings and Precautions (5.5), Drug Interactions (7.1), and Clinical Pharmacology (12.3)].

Treatment and Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism

Patients with severe renal impairment (CrCl ≤30 mL/min) were excluded from RE-COVER.

Dosing recommendations for patients with CrCl ≤30 mL/min or on dialysis cannot be provided. Avoid use of Pradaxa with concomitant P-gp inhibitors in patients with CrCl <50 mL/min [see Warnings and Precautions (5.5), Drug Interactions (7.2), and Clinical Pharmacology (12.3)].

Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery
Patients with severe renal impairment (CrCl <30 mL/min) were excluded from RE-NOVATE and RE-NOVATE II.

Dosing recommendations for patients with CrCl <30 mL/min or on dialysis cannot be provided.

Avoid use of Pradaxa with concomitant P-gp inhibitors in patients with CrCl <50 mL/min [see Warnings and Precautions (5.5), Drug Interactions (7.3) and Clinical Pharmacology (12.2, 12.3)].

Accidental overdose may lead to hemorrhagic complications. In the event of hemorrhagic complications, initiate appropriate clinical support, discontinue treatment with Pradaxa, and investigate the source of bleeding. A specific reversal agent (idarucizumab) is available.

Dabigatran is primarily eliminated by the kidneys with a low plasma protein binding of approximately 35%. Hemodialysis can remove dabigatran; however, data supporting this approach are limited. Using a high-flux dialyzer, blood flow rate of 200 mL/min, and dialysate flow rate of 700 mL/min, approximately 49% of total dabigatran can be cleared from plasma over 4 hours. At the same dialysate flow rate, approximately 57% can be cleared using a dialyzer blood flow rate of 300 mL/min, with no appreciable increase in clearance observed at higher blood flow rates. Upon cessation of hemodialysis, a redistribution effect of approximately 7% to 15% is seen. The effect of dialysis on dabigatran’s plasma concentration would be expected to vary based on patient specific characteristics. Measurement of aPTT or ECT may help guide therapy [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2)].

The chemical name for dabigatran etexilate mesylate, a direct thrombin inhibitor, is β-Alanine, N-[[2-[[[4-[[[(hexyloxy)carbonyl]amino]iminomethyl]phenyl]amino]methyl]-1-methyl-1H-benzimidazol-5-yl]carbonyl]-N-2-pyridinyl-,ethyl ester, methanesulfonate. The empirical formula is C34H41N7O5 ⋅ CH4O3S and the molecular weight is 723.86 (mesylate salt), 627.75 (free base). The structural formula is:

Dabigatran etexilate mesylate is a yellow-white to yellow powder. A saturated solution in pure water has a solubility of 1.8 mg/mL. It is freely soluble in methanol, slightly soluble in ethanol, and sparingly soluble in isopropanol.

Pradaxa capsules are supplied in 75, 110, and 150 mg strengths for oral administration. Each capsule contains dabigatran etexilate mesylate as the active ingredient: 172.95 mg dabigatran etexilate mesylate (equivalent to 150 mg dabigatran etexilate), 126.83 mg dabigatran etexilate mesylate (equivalent to 110 mg dabigatran etexilate), or 86.48 mg dabigatran etexilate mesylate (equivalent to 75 mg dabigatran etexilate) along with the following inactive ingredients: acacia, dimethicone, hypromellose, hydroxypropyl cellulose, talc, and tartaric acid. The capsule shell is composed of carrageenan, hypromellose, potassium chloride, titanium dioxide, black edible ink, and FD&C Blue No. 2 (150 mg and 110 mg capsules only).

 

 

 

Dabigatran and its acyl glucuronides are competitive, direct thrombin inhibitors. Because thrombin (serine protease) enables the conversion of fibrinogen into fibrin during the coagulation cascade, its inhibition prevents the development of a thrombus. Both free and clot-bound thrombin, and thrombin-induced platelet aggregation are inhibited by the active moieties.

At recommended therapeutic doses, dabigatran etexilate prolongs the coagulation markers such as aPTT, ECT, and TT. INR is relatively insensitive to the exposure to dabigatran and cannot be interpreted the same way as used for warfarin monitoring.

The aPTT test provides an approximation of Pradaxa’s anticoagulant effect. The average time course for effects on aPTT, following approved dosing regimens in patients with various degrees of renal impairment is shown in Figure 2. The curves represent mean levels without confidence intervals; variations should be expected when measuring aPTT. While advice cannot be provided on the level of recovery of aPTT needed in any particular clinical setting, the curves can be used to estimate the time to get to a particular level of recovery, even when the time since the last dose of Pradaxa is not precisely known. In the RE-LY trial, the median (10th to 90th percentile) trough aPTT in patients receiving the 150 mg dose was 52 (40 to 76) seconds.

Figure 2 Average Time Course for Effects of Dabigatran on aPTT, Following Approved Pradaxa Dosing Regimens in Patients with Various Degrees of Renal Impairment*

*Simulations based on PK data from a study in subjects with renal impairment and PK/aPTT relationships derived from the RE-LY study; aPTT prolongation in RE-LY was measured centrally in citrate plasma using PTT Reagent Roche Diagnostics GmbH,Mannheim,Germany. There may be quantitative differences between various established methods for aPTT assessment.

The degree of anticoagulant activity can also be assessed by the ecarin clotting time (ECT). This test is a more specific measure of the effect of dabigatran than activated partial thromboplastin time (aPTT). In the RE-LY trial, the median (10th to 90th percentile) trough ECT in patients receiving the 150 mg dose was 63 (44 to 103) seconds.

In orthopedic hip surgery patients, maximum aPTT response (Emax) to dabigatran and baseline aPTT were higher shortly after surgery than at later time points (e.g. ≥3 days after surgery).

Cardiac Electrophysiology

No prolongation of the QTc interval was observed with dabigatran etexilate at doses up to 600 mg.

Dabigatran etexilate mesylate is absorbed as the dabigatran etexilate ester. The ester is then hydrolyzed, forming dabigatran, the active moiety. Dabigatran is metabolized to four different acyl glucuronides and both the glucuronides and dabigatran have similar pharmacological activity. Pharmacokinetics described here refer to the sum of dabigatran and its glucuronides. Dabigatran displays dose-proportional pharmacokinetics in healthy subjects and patients in the range of doses from 10 to 400 mg.

Absorption

The absolute bioavailability of dabigatran following oral administration of dabigatran etexilate is approximately 3 to 7%. Dabigatran etexilate is a substrate of the efflux transporter P-gp. After oral administration of dabigatran etexilate in healthy volunteers, Cmax occurs at 1 hour post-administration in the fasted state. Coadministration of Pradaxa with a high-fat meal delays the time to Cmax by approximately 2 hours but has no effect on the bioavailability of dabigatran; Pradaxa may be administered with or without food.

The oral bioavailability of dabigatran etexilate increases by 75% when the pellets are taken without the capsule shell compared to the intact capsule formulation. Pradaxa capsules should therefore not be broken, chewed, or opened before administration.

Distribution

Dabigatran is approximately 35% bound to human plasma proteins. The red blood cell to plasma partitioning of dabigatran measured as total radioactivity is less than 0.3. The volume of distribution of dabigatran is 50 to 70 L. Dabigatran pharmacokinetics are dose proportional after single doses of 10 to 400 mg. Given twice daily, dabigatran’s accumulation factor is approximately two.

Elimination

Dabigatran is eliminated primarily in the urine. Renal clearance of dabigatran is 80% of total clearance after intravenous administration. After oral administration of radiolabeled dabigatran, 7% of radioactivity is recovered in urine and 86% in feces. The half-life of dabigatran in healthy subjects is 12 to 17 hours.

 

 

 

 

After oral administration, dabigatran etexilate is converted to dabigatran. The cleavage of the dabigatran etexilate by esterase-catalyzed hydrolysis to the active principal dabigatran is the predominant metabolic reaction. Dabigatran is not a substrate, inhibitor, or inducer of CYP450 enzymes. Dabigatran is subject to conjugation forming pharmacologically active acyl glucuronides. Four positional isomers, 1-O, 2-O, 3-O, and 4-O-acylglucuronide exist, and each accounts for less than 10% of total dabigatran in plasma.

Renal Impairment

An open, parallel-group single-center study compared dabigatran pharmacokinetics in healthy subjects and patients with mild to moderate renal impairment receiving a single dose of Pradaxa 150 mg. Exposure to dabigatran increases with severity of renal function impairment (Table 8). Similar findings were observed in the RE-LY, RE-COVER and RE-NOVATE II trials.

Table 8 Impact of Renal Impairment on Dabigatran Pharmacokinetics
+Patients with severe renal impairment were not studied in RE-LY, RE-COVER and RE-NOVATE II. Dosing recommendations in subjects with severe renal impairment are based on pharmacokinetic modeling [see Dosage and Administration (2.1, 2.2) and Use in Specific Populations (8.6)].
Renal Function	CrCl (mL/min)	Increase in AUC	Increase in Cmax	t1/2 (h)
Normal	≥ 80	1x	1x	13
Mild	50-80	1.5x	1.1x	15
Moderate	30-50	3.2x	1.7x	18
Severe+	15-30	6.3x	2.1x	27

Hepatic Impairment

Administration of Pradaxa in patients with moderate hepatic impairment (Child-Pugh B) showed a large inter-subject variability, but no evidence of a consistent change in exposure or pharmacodynamics.

Drug Interactions

A summary of the effect of coadministered drugs on dabigatran exposure is shown in Figures 3.1 and 3.2.

In the orthopedic hip surgery patients, limited clinical data with P-gp inhibitors is available.

In RE-LY, dabigatran plasma samples were also collected. The concomitant use of proton pump inhibitors, H2 antagonists, and digoxin did not appreciably change the trough concentration of dabigatran.

Impact of Dabigatran on Other Drugs
In clinical studies exploring CYP3A4, CYP2C9, P-gp and other pathways, dabigatran did not meaningfully alter the pharmacokinetics of amiodarone, atorvastatin, clarithromycin, diclofenac, clopidogrel, digoxin, pantoprazole, or ranitidine.

Dabigatran was not carcinogenic when administered by oral gavage to mice and rats for up to 2 years. The highest doses tested (200 mg/kg/day) in mice and rats were approximately 3.6 and 6 times, respectively, the human exposure at MRHD of 300 mg/day based on AUC comparisons.

Dabigatran was not mutagenic in in vitro tests, including bacterial reversion tests, mouse lymphoma assay and chromosomal aberration assay in human lymphocytes, and the in vivo micronucleus assay in rats.

In the rat fertility study with oral gavage doses of 15, 70, and 200 mg/kg, males were treated for 29 days prior to mating, during mating up to scheduled termination, and females were treated 15 days prior to mating through gestation Day 6. No adverse effects on male or female fertility were observed at 200 mg/kg or 9 to 12 times the human exposure at MRHD of 300 mg/day based on AUC comparisons. However, the number of implantations decreased in females receiving 70 mg/kg, or 3 times the human exposure at MRHD based on AUC comparisons.

 

 

 

The clinical evidence for the efficacy of Pradaxa was derived from RE-LY (Randomized Evaluation of Long-term Anticoagulant Therapy), a multi-center, multi-national, randomized parallel group trial comparing two blinded doses of Pradaxa (110 mg twice daily and 150 mg twice daily) with open-label warfarin (dosed to target INR of 2 to 3) in patients with non-valvular, persistent, paroxysmal, or permanent atrial fibrillation and one or more of the following additional risk factors:

· Previous stroke, transient ischemic attack (TIA), or systemic embolism

· Left ventricular ejection fraction <40%

· Symptomatic heart failure, ≥ New York Heart Association Class 2

· Age ≥75 years

· Age ≥65 years and one of the following: diabetes mellitus, coronary artery disease (CAD), or hypertension

The primary objective of this study was to determine if Pradaxa was non-inferior to warfarin in reducing the occurrence of the composite endpoint, stroke (ischemic and hemorrhagic) and systemic embolism. The study was designed to ensure that Pradaxa preserved more than 50% of warfarin’s effect as established by previous randomized, placebo-controlled trials of warfarin in atrial fibrillation. Statistical superiority was also analyzed.

A total of 18,113 patients were randomized and followed for a median of 2 years. The patients’ mean age was 71.5 years and the mean CHADS2 score was 2.1. The patient population was 64% male, 70% Caucasian, 16% Asian, and 1% black. Twenty percent of patients had a history of a stroke or TIA and 50% were Vitamin K antagonist (VKA) naïve, defined as less than 2 months total lifetime exposure to a VKA. Thirty-two percent of the population had never been exposed to a VKA. Concomitant diseases of patients in this trial included hypertension 79%, diabetes 23%, and CAD 28%. At baseline, 40% of patients were on aspirin and 6% were on clopidogrel. For patients randomized to warfarin, the mean percentage of time in therapeutic range (INR 2 to 3) was 64%.

Relative to warfarin and to Pradaxa 110 mg twice daily, Pradaxa 150 mg twice daily significantly reduced the primary composite endpoint of stroke and systemic embolism (see Table 9 and Figure 4).

The contributions of the components of the composite endpoint, including stroke by subtype, are shown in Table 10. The treatment effect was primarily a reduction in stroke. Pradaxa 150 mg twice daily was superior in reducing ischemic and hemorrhagic strokes relative to warfarin.

In the RE-LY trial, the rate of all-cause mortality was lower on dabigatran 150 mg than on warfarin (3.6% per year versus 4.1% per year). The rate of vascular death was lower on dabigatran 150 mg compared to warfarin (2.3% per year versus 2.7% per year). Non-vascular death rates were similar in the treatment arms.

 

The efficacy of Pradaxa 150 mg twice daily was generally consistent across major subgroups (see Figure 5).

Note: The figure above presents effects in various subgroups all of which are baseline characteristics and all of which were pre-specified. The 95% confidence limits that are shown do not take into account how many comparisons were made, nor do they reflect the effect of a particular factor after adjustment for all other factors. Apparent homogeneity or heterogeneity among groups should not be over-interpreted.

In RE-LY, a higher rate of clinical myocardial infarction was reported in patients who received Pradaxa (0.7 per 100 patient-years for 150 mg dose) than in those who received warfarin (0.6).

In the randomized, parallel group, double-blind trials, RE-COVER and RE-COVER II, patients with deep vein thrombosis and pulmonary embolism received Pradaxa 150 mg twice daily or warfarin (dosed to target INR of 2 to 3) following initial treatment with an approved parenteral anticoagulant for 5-10 days.

In RE-COVER, the median treatment duration during the oral only treatment period was 174 days. A total of 2539 patients (30.9% patients with symptomatic PE with or without DVT and 68.9% with symptomatic DVT only) were treated with a mean age of 54.7 years. The patient population was 58.4% male, 94.8% white, 2.6% Asian, and 2.6% black. The concomitant diseases of patients in this trial included hypertension (35.9%), diabetes mellitus (8.3%), coronary artery disease (6.5%), active cancer (4.8%), and gastric or duodenal ulcer (4.4%). Concomitant medications included agents acting on renin-angiotensin system (25.2%), vasodilators (28.4%), serum lipid-reducing agents (18.2%), NSAIDs (21%), beta-blockers (14.8%), calcium channel blockers (8.5%), ASA (8.6%), and platelet inhibitors excluding ASA (0.6%). Patients randomized to warfarin had a mean percentage of time in the INR target range of 2.0 to 3.0 of 60% in RE-COVER study.

In RE-COVER II, the median treatment duration during the oral only treatment period was 174 days. A total of 2568 patients (31.8% patients with symptomatic PE with or without DVT and 68.1% with symptomatic DVT only) were treated with a mean age of 54.9 years. The patient population was 60.6% male, 77.6% white, 20.9% Asian, and 1.5% black. The concomitant diseases of patients in this trial included hypertension (35.1%), diabetes mellitus (9.8%), coronary artery disease (7.1%), active cancer (3.9%), and gastric or duodenal ulcer (3.8%). Concomitant medications included agents acting on renin-angiotensin system (24.2%), vasodilators (28.6%), serum lipid-reducing agents (20.0%), NSAIDs (22.3%), beta-blockers (14.8%), calcium channel blockers (10.8%), ASA (9.8%), and platelet inhibitors excluding ASA (0.8%). Patients randomized to warfarin had a mean percentage of time in the INR target range of 2.0 to 3.0 of 57% in RE-COVER II study.

In studies RE-COVER and RE-COVER II, the protocol specified non-inferiority margin (2.75) for the hazard ratio was derived based on the upper limit of the 95% confidence interval of the historical warfarin effect. Pradaxa was demonstrated to be non-inferior to warfarin (dosed to target INR of 2 to 3) (Table 11) based on the primary composite endpoint (fatal PE or symptomatic non-fatal PE and/or DVT) and retains at least 66.9% (RE-COVER) and 63.9% (RE-COVER II) of the historical warfarin effect, respectively.

In the randomized, parallel group, double-blind, pivotal trial, RE-MEDY, patients received Pradaxa 150 mg twice daily or warfarin (dosed to target INR of 2 to 3) following 3 to 12 months of treatment with anticoagulation therapy for an acute VTE. The median treatment duration during the treatment period was 534 days. A total of 2856 patients were treated with a mean age of 54.6 years. The patient population was 61% male, and 90.1% white, 7.9% Asian and 2.0% black. The concomitant diseases of patients in this trial included hypertension (38.6%), diabetes mellitus (9.0%), coronary artery disease (7.2%), active cancer (4.2%), and gastric or duodenal ulcer (3.8%). Concomitant medications included agents acting on renin-angiotensin system (27.9%), vasodilators (26.7%), serum lipid reducing agents (20.6%), NSAIDs (18.3%), beta-blockers (16.3%), calcium channel blockers (11.1%), aspirin (7.7%), and platelet inhibitors excluding ASA (0.9%). Patients randomized to warfarin had a mean percentage of time in the INR target range of 2.0 to 3.0 of 62% in the study.

 

 

n study RE-MEDY, the protocol specified non-inferiority margin (2.85) for the hazard ratio was derived based on the point estimate of the historical warfarin effect. Pradaxa was demonstrated to be non-inferior to warfarin (dosed to target INR of 2 to 3) (Table 12) based on the primary composite endpoint (fatal PE or symptomatic non-fatal PE and/or DVT) and retains at least 63.0% of the historical warfarin effect. If the non-inferiority margin was derived based on the 50% retention of the upper limit of the 95% confidence interval, Pradaxa was demonstrated to retain at least 33.4% of the historical warfarin effect based on the composite primary endpoint.

In a randomized, parallel group, double-blind, pivotal trial, RE-SONATE, patients received Pradaxa 150 mg twice daily or placebo following 6 to 18 months of treatment with anticoagulation therapy for an acute VTE. The median treatment duration was 182 days. A total of 1343 patients were treated with a mean age of 55.8 years. The patient population was 55.5% male, 89.0% white, 9.3% Asian, and 1.7% black. The concomitant diseases of patients in this trial included hypertension (38.8%), diabetes mellitus (8.0%), coronary artery disease (6.0%), history of cancer (6.0%), gastric or duodenal ulcer (4.5%), and heart failure (4.6%). Concomitant medications included agents acting on renin-angiotensin system (28.7%), vasodilators (19.4%), beta-blockers (18.5%), serum lipid reducing agents (17.9%), NSAIDs (12.1%), calcium channel blockers (8.9%), aspirin (8.3%), and platelet inhibitors excluding ASA (0.7%). Based on the outcome of the primary composite endpoint (fatal PE, unexplained death, or symptomatic non-fatal PE and/or DVT), Pradaxa was superior to placebo (Table 13).

In the randomized, parallel group, double-blind, non-inferiority trials, RE-NOVATE and RE-NOVATE II patients received Pradaxa 75 mg orally 1-4 hours after surgery followed by 150 mg daily (RE-NOVATE), Pradaxa 110 mg orally 1-4 hours after surgery followed by 220 mg daily (RE-NOVATE and RE-NOVATE II) or subcutaneous enoxaparin 40 mg once daily initiated the evening before surgery (RE-NOVATE and RE-NOVATE II) for the prophylaxis of deep vein thrombosis and pulmonary embolism in patients who have undergone hip replacement surgery.

Overall, in RE-NOVATE and RE-NOVATE II, the median treatment duration was 33 days for Pradaxa and 33 days for enoxaparin. A total of 5428 patients were treated with a mean age of 63.2 years. The patient population was 45.3% male, 96.1% white, 3.6% Asian, and 0.4 % black. The concomitant diseases of patients in these trials included hypertension (46.1%), venous insufficiency (15.4%), coronary artery disease (8.2%), diabetes mellitus (7.9%), reduced renal function (5.3%), heart failure (3.4%), gastric or duodenal ulcer (3.0%), VTE (2.7%), and malignancy (0.1%). Concomitant medications included cardiac therapy (69.7%), NSAIDs (68%), vasoprotectives (29.7%), agents acting on renin-angiotensin system (29.1%), beta-blockers (21.5%), diuretics (20.8%), lipid modifying agents (18.2%), any antithrombin/anticoagulant (16.0%), calcium channel blockers (13.6%), low molecular weight heparin (7.8%), aspirin (7.0%), platelet inhibitors excluding ASA (6.9%), other antihypertensives (6.7%), and peripheral vasodilators (2.6%).

For efficacy evaluation all patients were to have bilateral venography of the lower extremities at 3 days after last dose of study drug unless an endpoint event had occurred earlier in the study. In the primary efficacy analysis, Pradaxa 110 mg orally 1-4 hours after surgery followed by 220 mg daily was non-inferior to enoxaparin 40 mg once daily in a composite endpoint of confirmed VTE (proximal or distal DVT on venogram, confirmed symptomatic DVT, or confirmed PE) and all cause death during the treatment period (Tables 14 and 15). In the studies 2628 (76.5%) patients in RE-NOVATE and 1572 (78.9%) patients in RE-NOVATE II had evaluable venograms at study completion.

MEDICATION GUIDE Pradaxa (pra dax a) (dabigatran etexilate mesylate) capsules
Read this Medication Guide before you start taking Pradaxa and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment.
What is the most important information I should know about Pradaxa? · For people taking Pradaxa for atrial fibrillation: People with atrial fibrillation (a type of irregular heartbeat) are at an increased risk of forming a blood clot in the heart, which can travel to the brain, causing a stroke, or to other parts of the body. Pradaxa lowers your chance of having a stroke by helping to prevent clots from forming. If you stop taking Pradaxa, you may have increased risk of forming a clot in your blood. Do not stop taking Pradaxa without talking to the doctor who prescribes it for you. Stopping Pradaxa increases your risk of having a stroke. Pradaxa may need to be stopped, if possible, prior to surgery or a medical or dental procedure. Ask the doctor who prescribed Pradaxa for you when you should stop taking it. Your doctor will tell you when you may start taking Pradaxa again after your surgery or procedure. If you have to stop taking Pradaxa, your doctor may prescribe another medicine to help prevent a blood clot from forming. · Pradaxa can cause bleeding which can be serious, and sometimes lead to death. This is because Pradaxa is a blood thinner medicine that lowers the chance of blood clots forming in your body. · You may have a higher risk of bleeding if you take Pradaxa and: o      are over 75 years old o      have kidney problems o      have stomach or intestine bleeding that is recent or keeps coming back, or you have a stomach ulcer o      take other medicines that increase your risk of bleeding, including: o        aspirin or aspirin containing products o        long-term (chronic) use of non-steroidal anti-inflammatory drugs (NSAIDs) o        warfarin sodium (Coumadin®, Jantoven®) o        a medicine that contains heparin o        clopidogrel bisulfate (Plavix®) o        prasugrel (Effient®)               have certain kidney problems and also take the medicines dronedarone (Multaq®) or ketoconazole tablets (Nizoral®). Tell your doctor if you take any of these medicines. Ask your doctor or pharmacist if you are not sure if your medicine is one listed above.         Pradaxa can increase your risk of bleeding because it lessens the ability of your blood to clot. While you take Pradaxa:               you may bruise more easily               it may take longer for any bleeding to stop Call your doctor or get medical help right away if you have any of these signs or symptoms of bleeding:               unexpected bleeding or bleeding that lasts a long time, such as: o        unusual bleeding from the gums o        nose bleeds that happen often o        menstrual bleeding or vaginal bleeding that is heavier than normal               bleeding that is severe or you cannot control               pink or brown urine               red or black stools (looks like tar)               bruises that happen without a known cause or get larger               cough up blood or blood clots               vomit blood or your vomit looks like “coffee grounds”               unexpected pain, swelling, or joint pain               headaches, feeling dizzy or weak Take Pradaxa exactly as prescribed. Do not stop taking Pradaxa without first talking to the doctor who prescribes it for you. Stopping Pradaxa may increase your risk of a stroke. Pradaxa may need to be stopped, if possible, for one or more days before any surgery, or medical or dental procedure. If you need to stop taking Pradaxa for any reason, talk to the doctor who prescribed Pradaxa for you to find out when you should stop taking it. Your doctor will tell you when to start taking Pradaxa again after your surgery or procedure.         Spinal or epidural blood clots (hematoma). People who take a blood thinner medicine (anticoagulant) like Pradaxa, and have medicine injected into their spinal and epidural area, or have a spinal puncture have a risk of forming a blood clot that can cause long-term or permanent loss of the ability to move (paralysis). Your risk of developing a spinal or epidural blood clot is higher if:               a thin tube called an epidural catheter is placed in your back to give you certain medicine.               you take NSAIDs or a medicine to prevent blood from clotting               you have a history of difficult or repeated epidural or spinal punctures               you have a history of problems with your spine or have had surgery on your spine.
