● 有与以前ACE抑制剂或ARB治疗相关血管水肿病史患者[见警告和注意事项(5.2)]
● 与ACE抑制剂的同时使用。转换从或至一个ACE抑制剂36小时内不要给予[见药物相互作用(7.1)]
● 在有糖尿病患者中同时使用阿利吉仑[见药物相互作用(7.1)].
5 警告和注意事项
5.1 胎儿毒性
当给予妊娠妇女ENTRESTO可能致胎儿危害。在妊娠的第二和第三个三个月期间使用作用在肾素-血管紧张素系统药物减低胎儿肾功能和增加胎儿和新生儿患病率和死亡。当检测到妊娠,考虑另外药物治疗和终止ENTRESTO。
但是,如对治疗没有适当替代影响肾素-血管紧张素系统药物,和如考虑药物挽救母亲生命,忠告妊娠妇女对胎儿潜在风险[见在特殊人群中使用(8.1)]。
5.2 血管水肿
ENTRESTO可能致血管水肿.。在PARADIGM-HF试验双盲期,用ENTRESTO治疗患者0.5%和用依那普利治疗患者[enalapril]0.2%有血管水肿[见不良反应(6.1)]。如发生血管水肿,立即终止ENTRESTO,提供适当治疗,和监视对气道损害。
ENTRESTO必须不再给予。确证的血管水肿情况中其中肿胀曾被局限于面和唇,情况一般地无治疗,虽然抗组胺药在缓解症状中曾有用。
血管水肿伴随喉头水肿可能是致命的。其中牵连舌,声门或咽喉,可能致气道阻塞,给予适当治疗,如,皮下肾上腺素[epinephrine/adrenaline]溶液1:1000(0.3 mL至0.5 mL)和需要采取措施确保患者气道的维持。
在黑种人中比非黑种人患者ENTRESTO曾伴随较高血管水肿发生率。
有既往血管水肿病史患者用ENTRESTO可能处于血管水肿的风险增高[见不良反应(6.1)]。在有已知与既往ACE抑制剂或ARB治疗相关血管水肿病史患者不应使用ENTRESTO[见禁忌证(4)]。
5.3 低血压
ENTRESTO降低血压和可能致症状性低血压。有一个活化的肾素-血管紧张素系统患者,例如容积- 和/或盐-耗竭患者(如,那些正在用高剂量利尿剂治疗),是处于更大风险。在PARADIGM-HF的双盲期,18%的用ENTRESTO治疗患者和12%的用依那普利治疗患者报道低血压作为一种不良事件[见不良反应(6.1)],在两个治疗臂报道约1.5%患者低血压为严重不良事件。ENTRESTO给药前或在一个较低剂量开始时纠正容积或盐耗竭。如发生低血压,考虑利尿剂,同时抗高血压药的剂量调整,和治疗低血压的其他原因(如,低血容量)。如尽管这类措施低血压持续,减低剂量或暂时地终止ENTRESTO。通常不需要永久终止治疗。
5.4 受损的肾功能
作为抑制肾素-血管紧张素-醛固酮系统(RAAS)的后果,在易感个体用ENTRESTO治疗可以预期肾功能减低。在PARADIGM-HF试验的双盲期中,在ENTRESTO和依那普利组都有5%的患者报道肾衰竭作为一种不良事件[见不良反应(6.1)]。在患者其肾功能依赖于肾素-血管紧张素-醛固酮系统的活性(如,患者有严重充血性心力衰竭),用ACE抑制剂和血管紧张素受体拮抗剂治疗曾伴随少尿,渐进氮质血症和,罕见地,急性肾衰竭和死亡。严密监视血清肌酐,和在患者发生临床上显著肾功能减低滴定下调整或中断ENTRESTO[见在特殊人群中使用(8.7)和临床药理学(12.3)]。
如同所有影响RAAS药物,在有双侧或单侧肾动脉狭窄患者ENTRESTO可能增加血尿素和血清肌酐水平。在有肾动脉狭窄患者,监视肾功能。
5.5 高钾血症
通过其对RAAS的作用,用ENTRESTO可能发生高钾血症。PARADIGM-HF试验的双盲期中,12%的用ENTRESTO治疗患者和14%的用依那普利治疗患者报道高钾血症作为一个不良事件[见不良反应(6.1)]。定期地监视血清钾和适当地治疗,尤其是在在有对高钾血症风险因子患者 例如严重肾受损,糖尿病,醛固酮减少症,或一个高钾膳食。可能需要剂量减少或中断ENTRESTO[见剂量和给药方法(2.1)]。
6 不良反应
在说明书的其他节中出现临床上显著不良反应包括:
● 血管水肿[见警告和注意事项(5.2)]
● 低血压[见警告和注意事项(5.3)]
● 受损的肾功能[见警告和注意事项(5.4)]
● 高钾血症[见警告和注意事项(5.5)]
6.1 临床试验经验
因为临床试验是在广泛不同情况下进行的,临床试验观察到不良反应率不能与另一种药临床试验发生率直接比较而且可能不反映实践中观察到的发生率。
在PARADIGM-HF试验中,进入随机化双盲期比较ENTRESTO和依那普利前,受试者被要求分别完成顺序依那普利和ENTRESTO磨合期(中位)15和29天。依那普利磨合期时,1,102例患者(10.5%)被永久地从研究终止,5.6%因为一种不良事件,大多数常是肾功能不全(1.7%),高钾血症(1.7%)和低血压(1.4%)。
ENTRESTO磨合期时,另外10.4%患者永久终止治疗,5.9%因为一个不良事件,大多数常是肾功能不全(1.8%),低血压(1.7%)和高钾血症(1.3%)。因为这个磨合设计,下面所述不良反应率是较低于实践。
在双盲期中,在4,203例用ENTRESTO治疗患者和4,229例用依那普利治疗患者被评价安全性。在PARADIGM-HF试验中,随机化至ENTRESTO患者接受治疗共至4.3年,有中位暴露时间24个月;3,271患者被治疗共超过一年。双盲期时ENTRESTO治疗患者因为一个不良事件终止治疗450(10.7%)而接受依那普利患者为516(12.2%)。
在表1中显示在双盲期中用ENTRESTO治疗患者以≥5%发生率发生的不良反应。
在PARADIGM-HF试验中,依那普利和ENTRESTO磨合期血管水肿的发生率两者是0.1%。
在双盲期,用ENTRESTO治疗患者血管水肿的发生率是较高于依那普利(分别0.5%和0.2%)。在黑种人患者用ENTRESTO血管水肿的发生率是2.4%和用依那普利0.5%[见警告和注意事项(5.2)]。
PARADIGM-HF的双盲期期间用ENTRESTO治疗患者2.1%报道姿势性昏厥[Orthostasis],与之比较用依那普利治疗患者为1.1%。用ENTRESTO治疗患者报道跌交1.9%相比较用依那普利治疗患者为1.3%。
实验室异常
血红蛋白和红细胞压积
在PARADIGM-HF试验双盲期观察到约5%ENTRESTO-和依那普利治疗患者在血红蛋白/红细胞压积都减低>20%。
血清肌酐
在依那普利磨合期观察到1.4%患者中血清肌酐增加>50%和在ENTRESTO磨合期中有2.2%患者。双盲期时,ENTRESTO-和依那普利-治疗患者均有约16%患者有血清肌酐增加 >50%。
血清钾
在依那普利和ENTRESTO磨合期都观察到约4%患者的钾浓度>5.5 mEq/L。在双盲期时,ENTRESTO-和依那普利治疗两者均有约16%患者钾浓度>5.5 mEq/L。
7 药物相互作用
7.1 肾素 - 血管紧张素 - 醛固酮系统[Renin-Angiotensin-Aldosterone系统]的双重阻断
禁忌ENTRESTO与一种ACE抑制剂同时使用因为增加血管水肿的风险[见禁忌证(4)]。
避免ENTRESTO与一个ARB使用,因为ENTRESTO含血管紧张素II受体阻断剂缬沙坦。
在有糖尿病患者中禁忌ENTRESTO与阿利吉仑的同时使用[见禁忌证(4)]。在有肾受损(eGFR <60 mL/min/1.73 m²)患者避免使用阿利吉仑。
7.2 保钾利尿剂
如同用阻断血管紧张素II或其作用其他药物,保钾利尿剂的同时使用(如, 螺甾内酯[spironolactone],氨苯蝶啶[triamterene],阿米洛利[amiloride]),钾补充剂,或含钾盐替代品可能导致血清钾增高[见警告和注意事项(5.5)].
7.3 非甾体抗炎药物(NSAIDs)包括选择性环氧化酶-2抑制剂(COX-2抑制剂)
在老年患者中,容积耗竭(包括那些用利尿药治疗),或有损害肾功能,NSAIDs的同时使用,包括COX-2抑制剂,用ENTRESTO可能导致肾功能恶化,包括可能急性肾衰竭。这些作用寻常是可逆的。定期监视肾功能。
7.4 锂
锂与血管紧张素II受体拮抗剂的同时给药时曾报道血清锂浓度增加和锂毒性。与ENTRESTO同时使用时监视血清锂水平。
8 在特殊人群中使用
8.1 妊娠
风险总结
当给予一位妊娠妇女时ENTRESTO可能致胎儿危害。妊娠的第二和低三个三个月时使用作用在肾素-血管紧张素系统药物减低胎儿肾功能和增加胎儿和新生儿患病率和死亡。大多数流行病学研究检查胎儿异常在第一个三个月降压使用暴露后不能区分影响肾素-血管紧张素系统药物和其他抗高血压药物。
在动物生殖研究中,在大鼠和兔器官形成期时ENTRESTO治疗导致胚胎-胎儿致死率增加和在兔中致畸胎性。当检测到妊娠,考虑另药治疗和终止ENTRESTO。但是,如对治疗没有适当影响肾素血管紧张素系统替代,和如药物被认为挽救母亲生命,忠告妊娠妇女对胎儿潜在风险。
不知道对适应证人群主要出生缺陷和流产的风险的估计背景。在美国一般人群中,在临床上承认妊娠主要出生缺陷和流产的风险的估计背景分别是2-4%和15-20%。
临床考虑
胎儿/新生儿不良反应
在羊水过少妊娠妇女在妊娠的第二和低三个三个月使用药物影响肾素-血管紧张素系统可能导致以下:减低胎儿肾功能导致无尿和肾衰竭,胎儿肺发育不良,骨骼异常,包括颅骨发育不全,低血压,和死亡。
进行系列超声检查评估羊膜腔内环境。胎儿测试可能是适当的,根据怀孕周数。患者和医生应被认识到,但是,直至胎儿已持续不可逆地损伤羊水过少可能出现。如观察到羊水过少考虑替代药物治疗。
密切观察有在子宫内暴露于ENTRESTO对低血压,少尿,和高钾血症史新生儿。
在有子宫内暴露至ENTRESTO病史新生儿,如发生少尿或低血压,支持血压和肾灌流。可能需要交换输血或透析作为逆转低血压和置换肾功能的措施。
数据
动物数据
在大鼠在剂量≥49 mg sacubitril/51 mg缬沙坦/kg/day(≤ 0.14[LBQ657,活性代谢物]和在血浆药物浓度时间曲线下面积[AUC])基础上最大推荐人用剂量[MRHD]97/103 mg每天2次[缬沙坦]1.5-倍和兔在剂量 ≥ 5 mg sacubitril/5 mg缬沙坦/kg/day(缬沙坦和LBQ657 AUC的基础上MRHD分别4-倍和0.06-倍时,器官形成期时ENTRESTO治疗导致胚胎-胎儿致死率增加。根据一个胎儿脑积水低发生率,伴随母体毒性剂量,被观察到在兔中在ENTRESTO剂量 ≥ 5 mg sacubitril/5 mg缬沙坦/kg/dayENTRESTO是致畸胎的。ENTRESTO的不良胚胎-胎儿效应是归咎于血管紧张素受体拮抗剂活性。
在大鼠中围产期发育研究在sacubitril剂量至750 mg/kg/day(在LBQ657 AUC的基础上MRHD 4.5-倍)和缬沙坦在剂量至600 mg/kg/day(在AUC基础上MRHD 0.86-倍)表明器官形成期,怀孕和哺乳时用ENTRESTO治疗可能影响幼畜发育和生存。
8.2 哺乳
风险总结
没有关于在人乳中存在sacubitril/缬沙坦的资料,对哺乳喂养婴儿影响,或对乳汁生成影响。 Sacubitril/缬沙坦存在大鼠乳汁中。因为在哺乳喂养中婴儿来自sacubitril/缬沙坦暴露对严重不良反应潜能,忠告一位哺乳妇女建议用ENTRESTO治疗时不要哺乳喂养。
数据
对哺乳大鼠一个[14C]ENTRESTO口服剂量(15 mg sacubitril/15 mg缬沙坦/kg)后,观察到LBQ657的转运至乳汁。一个单次口服给予3 mg/kg[14C]缬沙坦至哺乳大鼠后,观察到缬沙坦转运至乳汁。
8.4 儿童使用
尚未确定在儿童患者中安全性和有效性。
8.5 老年人使用
在老年人(≥65岁)或非常老年(≥75岁)患者与总体人群比较未曾观察到相关药代动力学差别[见临床药理学(12.3)]。
8.6 肝受损
对有轻度肝受损(Child-Pugh A分类)患者当给予ENTRESTO时无需剂量调整。在有中度肝受损(Child-Pugh B分类)患者推荐起始剂量为24/26 mg每天2次。建议在有严重肝受损(Child-Pugh C分类)患者不使用ENTRESTO,因为在这些患者未进行研究[见剂量和给药方法(2.4),临床药理学(12.3)]。
8.7 肾受损
在有轻度(eGFR 60至90 mL/min/1.73 m2)至中度(eGFR 30至60 mL/min/1.73 m2)肾受损患者无需剂量调整。在有严重肾受损(eGFR <30 mL/min/1.73 m2)患者中推荐起始剂量是24/26 mg每天2次[见剂量和给药方法(2.3),警告和注意事项(5.4)和临床药理学(12.3)]。
10 药物过量
在人受试者用ENTRESTO药物过量可得到数据有限。在健康志愿者中,曾研究一个单剂量 ENTRESTO 583 mg sacubitril/617 mg缬沙坦,和多次剂量437 mg sacubitril/463 mg缬沙坦(14 天)和被很好耐受。
低血压是药物过量最可能结果由于ENTRESTO降低血压的作用。
应提供对症治疗。
因为高蛋白结合ENTRESTO不可能通过血液透析去除。
11 一般描述
ENTRESTO(sacubitril和缬沙坦[valsartan])是一种脑啡肽酶抑制剂和一种血管紧张素II受体阻断剂组合。
ENTRESTO含一种sacubitril的阴离子形式和缬沙坦,钠离子,和水分子分别以1:1:3:2.5的摩尔比组成复合物。口服给药后,复合物解离为sacubitril(它被进一步代谢至LBQ657)和缬沙坦。复合物在化学上被描述为 Octadecasodiumhexakis(4-{[(1S,3R)-1-([1,1´-biphenyl]-4-ylmethyl)-4-ethoxy-3-methyl-4-oxobutyl]amino}-4-oxobutanoate)hexakis(N-pentanoyl-N-{[2´-(1H-tetrazol-1-id-5-yl)[1,1´-biphenyl]-4-yl]methyl}-L-valinate)—水(1/15)。
它的经验式(半五水合物[hemipentahydrate])是C48H55N6O8Na3 2.5 H2O。其分子质量为957.99和其原理结构式为:
可得到为口服给药ENTRESTO为薄膜包衣片,含24 mg的sacubitril和26 mg缬沙坦;49 mg的sacubitril和51 mg缬沙坦;和97 mg的sacubitril和103 mg缬沙坦。片无活性成分为微晶纤维素,低取代羟丙基纤维素,交联聚乙烯吡咯烷酮,硬脂酸镁(植物来源),滑石,和胶体二氧化硅。薄膜包衣无活性成分为羟丙甲纤维素,二氧化钛(E 171),聚乙二醇4000,滑石,和氧化铁红(E 172)。对24 mg的sacubitril和26 mg缬沙坦片和97 mg的sacubitril和103 mg缬沙坦片的薄膜包衣还含氧化铁黑(E 172)。对49 mg的sacubitril和51 mg缬沙坦片薄膜包衣含氧化铁黄(E 172)。
12 临床药理学
12.1 作用机制
ENTRESTO含一种脑啡肽酶抑制剂,sacubitril,和一种血管紧张素受体阻断剂,缬沙坦。ENTRESTO抑制脑啡肽酶(中性内肽酶;NEP)通过LBQ657,前药sacubitril的活性代谢物,和通过缬沙坦阻断血管紧张素II类型-1(AT1)受体。ENTRESTO在心力衰竭患者中心血管和肾效应是归咎于被脑啡肽酶降解多肽水平的增加,例如利钠肽被LBQ657,和同时被缬沙坦的血管紧张素II抑制作用。缬沙坦抑制通过血管紧张素II选择性阻断AT1受体效应,和还抑制血管紧张素II-依赖的醛固酮释放。
12.2 药效动力学
在健康受试者和在有心力衰竭患者中单次和多次剂量给药后评价ENTRESTO的药效动力学 效应,和是与同时脑啡肽酶抑制作用和肾素-血管紧张素系统阻断一致。在一项7-天缬沙坦-对照研究在有减低射血分数(HFrEF)患者中, ENTRESTO的给药与缬沙坦比较导致一个显著非-持续尿钠排泄增加,尿cGMP增加,和血浆MR-proANP和NT-proBNP减低。.
在一项在HFrEF患者21-天研究中,ENTRESTO显著增加尿ANP和cGMP和血浆cGMP,和减低血浆NT-proBNP,醛固酮和内皮素-1。ENTRESTO还阻断AT1-受体如证据 evidenced by血浆肾素活性和血浆肾素浓度增加。在PARADIGM-HF试验中,与依那普利比较ENTRESTO减低血浆NTproBNP(不是一种脑啡肽酶底物)和增加血浆BNP(一种脑啡肽酶底物)和尿cGMP。
QT延长:在健康男性受试者中一项彻底的QTc临床研究,单剂量ENTRESTO 194 mg sacubitril/206 mg缬沙坦和583 mg sacubitril/617 mg缬沙坦对心脏复极化无影响。
淀粉样蛋白-β:脑啡肽酶是涉及从脑和脑脊液(CSF)淀粉样蛋白-β(Aβ)清除多种酶之一。健康受试者给予ENTRESTO 194 mg sacubitril/206 mg缬沙坦每天1次共2周与安慰剂比较在SF中Aβ1-38增加;CSF Aβ1-40或CSF Aβ1-42的浓度没有变化。这个发现的临床相关性不知道[见非临床毒理学(13)]。
血压:在高血压患者中添加一个50 mg单剂量西地那非[sildenafil]至ENTRESTO在稳态(194 mg sacubitril/206 mg缬沙坦mg每天1次共5天)与单独给予ENTRESTO比较伴随血压另外减低(~5/4 mmHg,收缩/舒张压)。
ENTRESTO的共同给药不显著改变静脉硝酸甘油[nitroglycerin]血压的影响。
12.3 药代动力学
吸收
口服给药后,ENTRESTO解离至sacubitril和缬沙坦。Sacubitril被进一步代谢至LBQ657。分别在0.5小时,2小时,和1.5小时达到Sacubitril,LBQ657,和缬沙坦的血浆峰浓度。Sacubitril的口服绝对生物利用度估算将是≥ 60%。在ENTRESTO中缬沙坦比缬沙坦在其他上市片剂中更生物可利用;在ENTRESTO的26 mg,51 mg,和103 mg缬沙坦是分别等同于在其他上市片剂中的40 mg,80 mg,和160 mg缬沙坦。
每天2次ENTRESTO给药后, sacubitril,LBQ657,和缬沙坦在3天中达到的稳态水平。在稳态时,sacubitril和缬沙坦不显著积蓄,而LBQ657积蓄1.6-倍。
ENTRESTO与食物给予对对sacubitril,LBQ657,或缬沙坦的全身暴露无临床上显著影响。虽然当ENTRESTO与食物给予对缬沙坦暴露中有减低,这个减低不伴随临床上治疗效应的显著减低。因此ENTRESTO可与食物或无食物给予。
分布
Sacubitril,LBQ657和缬沙坦是与血浆蛋白高度结合(94%至97%)。根据血浆和CSF暴露的比较,LBQ657跨越血脑屏障至有限程度(0.28%)。缬沙坦和sacubitril的平均表观分布容积分别为75和103 L。
代谢
Sacubitril被酯酶迅速地转换为LBQ657;LBQ657不进一步代谢至显著程度。
缬沙坦是很小地被代谢;只有约20%的剂量作为代谢物被回收。在血浆中曾在低浓度被鉴定为羟基代谢物(< 10%)。
消除
口服给药后, 52%至68%的sacubitril(主要地为LBQ657)和~13%的缬沙坦及其代谢物被排泄在尿中;37%至48%的sacubitril(主要地为LBQ657),和86%的缬沙坦及其代谢物在粪中被排泄。Sacubitril,LBQ657,和缬沙坦从血浆被消除有一个均数消除半衰期(T1/2)分别约为1.4小时,11.5小时,和9.9小时。
线性/非线性
跨越ENTRESTO剂量范围24 mg sacubitril/26 mg缬沙坦至194 mg sacubitril/206 mg缬沙坦,Sacubitril,LBQ657,和缬沙坦的药代动力学是线性。
药物相互作用:

13.1 癌发生,突变发生,生育力受损
癌发生和突变发生
在小鼠和大鼠中用sacubitril和缬沙坦进行致癌性研究对ENTRESTO没有确定任何致癌性潜能。 在雄性和雌性小鼠中在高剂量(HD)1200 mg/kg/day LBQ657 Cmax 分别为在人时的14和16倍 。在雄性和雌性大鼠在HD 400 mg/kg/day时LBQ657 Cmax分别是人MRHD的1.7和3.5倍。被研究缬沙坦的剂量(在小鼠和大鼠中高剂量分别为160和200 mg/kg/day)在mg/m2的基础上分别是MRHD约4和10倍。
用ENTRESTO,sacubitril,和缬沙坦进行致突变性和致畸变性研究没有揭示在或基因或染色体水平上任何影响。
生育力受损
在大鼠中直至剂量ENTRESTO 73 mg sacubitril/77 mg缬沙坦/kg/day(在缬沙坦和LBQ657 AUCs的基础上分别为MRHD的≤1.0-倍和≤ 0.18-倍)未显示对生育力任何影响。
13.2 动物毒理学和/或药理学
在年小(2至4岁)食蟹猴用ENTRESTO(24 mg sacubitril/26 mg缬沙坦/kg/day治疗的)共2周评估ENTRESTO对在CSF和脑组织中淀粉样蛋白-β浓度的影响。在这项研究中, ENTRESTO 影响CSF Aβ清除,增加在CSF中CSF Aβ 1-40,1-42,和1-38水平;在脑中Aβ水平没有相应的增加 。此外,在一项毒理学研究在食蟹猴用ENTRESTO在146 mg sacubitril/154 mg缬沙坦/kg/day共39-周,在脑中没有淀粉样蛋白-β积蓄。
14 临床研究
在临床试验中给药是根据ENTRESTO的两个组分的总量,即,24/26 mg,49/51 mg和97/103 mg 分别被简称为50 mg,100 mg,和200 mg。
PARADIGM-HF PARADIGM-HF是一项多国,随机化,双盲试验比较ENTRESTO和依那普利 在8,442例有症状性慢性心力衰竭(NYHA类别II–IV)和收缩功能不全(左心室射血分数 ≤ 40%)的成年患者。患者必须曾用一种血管紧张素转化酶[ACE]抑制剂或血管紧张素II受体阻断剂[ARB]共至少四周和用β-阻断剂的最大耐受剂量。排除在筛选时有收缩压 < 100 mmHg患者。
PARADIGM-HF的主要目的是确定whether ENTRESTO,sacubitril和一个RAS[肾素血管紧张素系统]抑制剂(缬沙坦)的联用,在对心力衰竭(HF)减低心血管(CV)死亡或住院组合终点的风险是否优于单独一个RAS抑制剂(依那普利)。
终止他们的已存在ACE抑制剂或ARB治疗后,患者进入顺序单-盲磨合期时其中他们接受依那普利10 mg每天2次,接着ENTRESTO 100 mg每天2次,增加至200 mg每天2次。成功地完成顺序磨合期患者被随机化接受或ENTRESTO 200 mg(N=4,209)每天2次或依那普利10 mg(N=4,233)每天2次。主要终点是对心衰CV死亡或住院的复合中首次事件。中位随访时间为27个月而患者被治疗共至 4.3年。
人群是66%高加索人,18%亚裔,和5%黑种人;均数年龄为64岁和78%为男性。在随机化时,70%患者是NYHA类别II,24%是NYHA类别III,和0.7%是NYHA类别IV。均数左心室射血分数为29%。60%患者心力衰竭原因是冠状动脉疾病;71%有高血压史,43%有心肌梗死史,37% 有一个eGFR < 60 mL/min/1.73m2,和35%有糖尿病。大多数患者正在用β-阻断剂(94%),盐皮质激素受体拮抗剂(58%),和利尿剂(82%)。少数患者有一个植入式心脏复律除颤器(ICD)或心脏再同步化治疗-除颤器(CRT-D)(15%)。
PARADIGM-HF显示ENTRESTO,一个sacubitril和一个RAS抑制剂(缬沙坦)的组合,是优于一个RAS抑制剂(依那普利),在减低对心力衰竭心血管死亡或住院复合终点的风险,根据一个时间-至-事件分析(危害比[HR]:0.80,95%可信区间[CI], 0.73,0.87,p <0.0001)。治疗效应反映在心血管死亡和心力衰竭住院两者减低;见表2和图3。突然死亡占45%心血管死亡,接着是泵衰竭,它占26%。
ENTRESTO还改善总生存(HR 0.84; 95% CI[0.76,0.93],p = 0.0009)(表2).。这个发现为完全被用ENTRESTO心血管死亡率较低发生率驱动。

WARNING: FETAL TOXICITY
· When pregnancy is detected, discontinue Entresto as soon as possible (5.1)
· Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus (5.1)
INDICATIONS AND USAGE Heart Failure
Entresto is indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in patients with chronic heart failure (NYHA Class II-IV) and reduced ejection fraction.
Entresto is usually administered in conjunction with other heart failure therapies, in place of an ACE inhibitor or other ARB.
DOSAGE AND ADMINISTRATION Dosing
Entresto is contraindicated with concomitant use of an angiotensin-converting enzyme (ACE) inhibitor. If switching from an ACE inhibitor to Entresto allow a washout period of 36 hours between administration of the two drugs [see Contraindications (4) and Drug Interactions (7.1)].
The recommended starting dose of Entresto is 49/51 mg twice-daily.
Double the dose of Entresto after 2 to 4 weeks to the target maintenance dose of 97/103 mg twice daily, as tolerated by the patient.
Dose Adjustment for Patients Not Taking an ACE inhibitor or ARB or Previously Taking Low Doses of These Agents
A starting dose of 24/26 mg twice-daily is recommended for patients not currently taking an ACE inhibitor or an angiotensin II receptor blocker (ARB) and for patients previously taking low doses of these agents. Double the dose of Entresto every 2 to 4 weeks to the target maintenance dose of 97/103 mg twice daily, as tolerated by the patient.
Dose Adjustment for Severe Renal Impairment
A starting dose of 24/26 mg twice-daily is recommended for patients with severe renal impairment (eGFR < 30 mL/min/1.73 m2). Double the dose of Entresto every 2 to 4 weeks to the target maintenance dose of 97/103 mg twice daily, as tolerated by the patient.
No starting dose adjustment is needed for mild or moderate renal impairment.
Dose Adjustment for Hepatic Impairment
A starting dose of 24/26 mg twice-daily is recommended for patients with moderate hepatic impairment (Child-Pugh B classification). Double the dose of Entresto every 2 to 4 weeks to the target maintenance dose of 97/103 mg twice daily, as tolerated by the patient.
No starting dose adjustment is needed for mild hepatic impairment.
Use in patients with severe hepatic impairment is not recommended.

· in patients with hypersensitivity to any component
· in patients with a history of angioedema related to previous ACE inhibitor or ARB therapy [see Warnings and Precautions (5.2)]
· with concomitant use of ACE inhibitors. Do not administer within 36 hours of switching from or to an ACE inhibitor [see Drug Interactions (7.1)]
· with concomitant use of aliskiren in patients with diabetes [see Drug Interactions (7.1)]
WARNINGS AND PRECAUTIONS Fetal Toxicity
Entresto can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. When pregnancy is detected, consider alternative drug treatment and discontinue Entresto. However, if there is no appropriate alternative to therapy with drugs affecting the renin-angiotensin system, and if the drug is considered lifesaving for the mother, advise a pregnant woman of the potential risk to the fetus [see Use in Specific Populations (8.1)].
Angioedema
Entresto may cause angioedema. In the double-blind period of PARADIGM-HF, 0.5% of patients treated with Entresto and 0.2% of patients treated with enalapril had angioedema [see Adverse Reactions (6.1)]. If angioedema occurs, discontinue Entresto immediately, provide appropriate therapy, and monitor for airway compromise. Entresto must not be re-administered. In cases of confirmed angioedema where swelling has been confined to the face and lips, the condition has generally resolved without treatment, although antihistamines have been useful in relieving symptoms.
Angioedema associated with laryngeal edema may be fatal. Where there is involvement of the tongue, glottis or larynx, likely to cause airway obstruction, administer appropriate therapy, e.g., subcutaneous epinephrine/adrenaline solution 1:1000 (0.3 mL to 0.5 mL) and take measures necessary to ensure maintenance of a patent airway.
Entresto has been associated with a higher rate of angioedema in Black than in non-Black patients.
Patients with a prior history of angioedema may be at increased risk of angioedema with Entresto [see Adverse Reactions (6.1)]. Entresto must not be used in patients with a known history of angioedema related to previous ACE inhibitor or ARB therapy [see Contraindications (4)]. Entresto should not be used in patients with hereditary angioedema.
Hypotension
Entresto lowers blood pressure and may cause symptomatic hypotension. Patients with an activated renin-angiotensin system, such as volume- and/or salt-depleted patients (e.g., those being treated with high doses of diuretics), are at greater risk. In the double-blind period of PARADIGM-HF, 18% of patients treated with Entresto and 12% of patients treated with enalapril reported hypotension as an adverse event [see Adverse Reactions (6.1)], with hypotension reported as a serious adverse event in approximately 1.5% of patients in both treatment arms. Correct volume or salt depletion prior to administration of Entresto or start at a lower dose. If hypotension occurs, consider dose adjustment of diuretics, concomitant antihypertensive drugs, and treatment of other causes of hypotension (e.g., hypovolemia). If hypotension persists despite such measures, reduce the dosage or temporarily discontinue Entresto. Permanent discontinuation of therapy is usually not required.
Impaired Renal Function
As a consequence of inhibiting the renin-angiotensin-aldosterone system (RAAS), decreases in renal function may be anticipated in susceptible individuals treated with Entresto. In the double-blind period of PARADIGM-HF, 5% of patients in both the Entresto and enalapril groups reported renal failure as an adverse event [see Adverse Reactions (6.1)]. In patients whose renal function depends upon the activity of the renin-angiotensin-aldosterone system (e.g., patients with severe congestive heart failure), treatment with ACE inhibitors and angiotensin receptor antagonists has been associated with oliguria, progressive azotemia and, rarely, acute renal failure and death. Closely monitor serum creatinine, and down-titrate or interrupt Entresto in patients who develop a clinically significant decrease in renal function [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].
As with all drugs that affect the RAAS, Entresto may increase blood urea and serum creatinine levels in patients with bilateral or unilateral renal artery stenosis. In patients with renal artery stenosis, monitor renal function.
Hyperkalemia
Through its actions on the RAAS, hyperkalemia may occur with Entresto. In the double-blind period of PARADIGM-HF, 12% of patients treated with Entresto and 14% of patients treated with enalapril reported hyperkalemia as an adverse event [see Adverse Reactions (6.1)]. Monitor serum potassium periodically and treat appropriately, especially in patients with risk factors for hyperkalemia such as severe renal impairment, diabetes, hypoaldosteronism, or a high potassium diet. Dosage reduction or interruption of Entresto may be required [see Dosage and Administration (2.1)].
ADVERSE REACTIONS
Clinically significant adverse reactions that appear in other sections of the labeling include:
Angioedema [see Warnings and Precautions (5.2)]Hypotension [see Warnings and Precautions (5.3)]Impaired Renal Function [see Warnings and Precautions (5.4)]Hyperkalemia [see Warnings and Precautions (5.5)] 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.
In the PARADIGM-HF trial, subjects were required to complete sequential enalapril and Entresto run-in periods of (median) 15 and 29 days, respectively, prior to entering the randomized double-blind period comparing Entresto and enalapril. During the enalapril run-in period, 1,102 patients (10.5%) were permanently discontinued from the study, 5.6% because of an adverse event, most commonly renal dysfunction (1.7%), hyperkalemia (1.7%) and hypotension (1.4%). During the Entresto run-in period, an additional 10.4% of patients permanently discontinued treatment, 5.9% because of an adverse event, most commonly renal dysfunction (1.8%), hypotension (1.7%) and hyperkalemia (1.3%). Because of this run-in design, the adverse reaction rates described below are lower than expected in practice.
In the double-blind period, safety was evaluated in 4,203 patients treated with Entresto and 4,229 treated with enalapril. In PARADIGM-HF, patients randomized to Entresto received treatment for up to 4.3 years, with a median duration of exposure of 24 months; 3,271 patients were treated for more than one year. Discontinuation of therapy because of an adverse event during the double-blind period occurred in 450 (10.7%) of Entresto treated patients and 516 (12.2%) of patients receiving enalapril.
Adverse reactions occurring at an incidence of ≥ 5% in patients who were treated with Entresto in the double-blind period are shown in Table 1.

In the PARADIGM-HF trial, the incidence of angioedema was 0.1% in both the enalapril and Entresto run-in periods. In the double-blind period, the incidence of angioedema was higher in patients treated with Entresto than enalapril (0.5% and 0.2%, respectively). The incidence of angioedema in Black patients was 2.4% with Entresto and 0.5% with enalapril [see Warnings and Precautions (5.2)].
Orthostasis was reported in 2.1% of patients treated with Entresto compared to 1.1% of patients treated with enalapril during the double-blind period of PARADIGM-HF. Falls were reported in 1.9% of patients treated with Entresto compared to 1.3% of patients treated with enalapril.
Laboratory Abnormalities
Hemoglobin and Hematocrit
Decreases in hemoglobin/hematocrit of > 20% were observed in approximately 5% of both Entresto- and enalapril-treated patients in the double-blind period in PARADIGM-HF.
Serum Creatinine
Increases in serum creatinine of > 50% were observed in 1.4% of patients in the enalapril run-in period and 2.2% of patients in the Entresto run-in period. During the double-blind period, approximately 16% of both Entresto- and enalapril-treated patients had increases in serum creatinine of > 50%.
Serum Potassium
Potassium concentrations > 5.5 mEq/L were observed in approximately 4% of patients in both the enalapril and Entresto run-in periods. During the double-blind period, approximately 16% of both Entresto- and enalapril-treated patients had potassium concentrations > 5.5 mEq/L.
Postmarketing Experience
The following additional adverse reactions have been reported in postmarketing experience. 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.
Hypersensitivity including rash, pruritus, and anaphylactic reaction
DRUG INTERACTIONS Dual Blockade of the Renin-Angiotensin-Aldosterone System
Concomitant use of Entresto with an ACE inhibitor is contraindicated because of the increased risk of angioedema [see Contraindications (4)].
Avoid use of Entresto with an ARB, because Entresto contains the angiotensin II receptor blocker valsartan.
The concomitant use of Entresto with aliskiren is contraindicated in patients with diabetes [see Contraindications (4)]. Avoid use with aliskiren in patients with renal impairment (eGFR < 60 mL/min/1.73 m2).
Potassium-Sparing Diuretics
As with other drugs that block angiotensin II or its effects, concomitant use of potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride), potassium supplements, or salt substitutes containing potassium may lead to increases in serum potassium [see Warnings and Precautions (5.5)].
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) Including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors)
In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, concomitant use of NSAIDs, including COX-2 inhibitors, with Entresto may result in worsening of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically.
Lithium
Increases in serum lithium concentrations and lithium toxicity have been reported during concomitant administration of lithium with angiotensin II receptor antagonists. Monitor serum lithium levels during concomitant use with Entresto.
USE IN SPECIFIC POPULATIONS Pregnancy
Risk Summary
Entresto can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. In animal reproduction studies, Entresto treatment during organogenesis resulted in increased embryo-fetal lethality in rats and rabbits and teratogenicity in rabbits. When pregnancy is detected, consider alternative drug treatment and discontinue Entresto. However, if there is no appropriate alternative to therapy with drugs affecting the renin-angiotensin system, and if the drug is considered lifesaving for the mother, advise a pregnant woman of the potential risk to the fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Oligohydramnios in pregnant women who use drugs affecting the renin-angiotensin system in the second and third trimesters of pregnancy can result in the following: reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension, and death.
Perform serial ultrasound examinations to assess the intra-amniotic environment. Fetal testing may be appropriate, based on the week of gestation. Patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. If oligohydramnios is observed, consider alternative drug treatment. Closely observe neonates with histories of in utero exposure to Entresto for hypotension, oliguria, and hyperkalemia. In neonates with a history of in utero exposure to Entresto, if oliguria or hypotension occurs, support blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as a means of reversing hypotension and replacing renal function.
Data
Animal Data
Entresto treatment during organogenesis resulted in increased embryo-fetal lethality in rats at doses ≥ 49 mg sacubitril/51 mg valsartan/kg/day (≤ 0.14 [LBQ657, the active metabolite] and 1.5 [valsartan]-fold the maximum recommended human dose [MRHD] of 97/103 mg twice-daily on the basis of the area under the plasma drug concentration-time curve [AUC]) and rabbits at doses ≥ 5 mg sacubitril/5 mg valsartan/kg/day (4-fold and 0.06-fold the MRHD on the basis of valsartan and LBQ657 AUC, respectively). Entresto is teratogenic based on a low incidence of fetal hydrocephaly, associated with maternally toxic doses, which was observed in rabbits at an Entresto dose of ≥ 5 mg sacubitril/5 mg valsartan/kg/day. The adverse embryo-fetal effects of Entresto are attributed to the angiotensin receptor antagonist activity.
Pre- and postnatal development studies in rats at sacubitril doses up to 750 mg/kg/day (4.5-fold the MRHD on the basis of LBQ657 AUC) and valsartan at doses up to 600 mg/kg/day (0.86-fold the MRHD on the basis of AUC) indicate that treatment with Entresto during organogenesis, gestation and lactation may affect pup development and survival.
Lactation
Risk Summary
There is no information regarding the presence of sacubitril/valsartan in human milk, the effects on the breastfed infant, or the effects on milk production. Sacubitril/valsartan is present in rat milk. Because of the potential for serious adverse reactions in breastfed infants from exposure to sacubitril/valsartan, advise a nursing woman that breastfeeding is not recommended during treatment with Entresto.
Data
Following an oral dose (15 mg sacubitril/15 mg valsartan/kg) of [14C] Entresto to lactating rats, transfer of LBQ657 into milk was observed. After a single oral administration of 3 mg/kg [14C] valsartan to lactating rats, transfer of valsartan into milk was observed.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established.
Geriatric Use
No relevant pharmacokinetic differences have been observed in elderly (≥ 65 years) or very elderly (≥ 75 years) patients compared to the overall population [see Clinical Pharmacology (12.3)].
Hepatic Impairment
No dose adjustment is required when administering Entresto to patients with mild hepatic impairment (Child-Pugh A classification). The recommended starting dose in patients with moderate hepatic impairment (Child-Pugh B classification) is 24/26 mg twice daily. The use of Entresto in patients with severe hepatic impairment (Child-Pugh C classification) is not recommended, as no studies have been conducted in these patients [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)].
Renal Impairment
No dose adjustment is required in patients with mild (eGFR 60 to 90 mL/min/1.73 m2) to moderate (eGFR 30 to 60 mL/min/1.73 m2) renal impairment. The recommended starting dose in patients with severe renal impairment (eGFR < 30 mL/min/1.73 m2) is 24/26 mg twice daily [see Dosage and Administration (2.3), Warnings and Precautions (5.4) and Clinical Pharmacology (12.3)].
OVERDOSAGE
Limited data are available with regard to overdosage in human subjects with Entresto. In healthy volunteers, a single dose of Entresto 583 mg sacubitril/617 mg valsartan, and multiple doses of 437 mg sacubitril/463 mg valsartan (14 days) have been studied and were well tolerated.
Hypotension is the most likely result of overdosage due to the blood pressure lowering effects of Entresto. Symptomatic treatment should be provided.
Entresto is unlikely to be removed by hemodialysis because of high protein binding.
DESCRIPTION
Entresto (sacubitril and valsartan) is a combination of a neprilysin inhibitor and an angiotensin II receptor blocker.
Entresto contains a complex comprised of anionic forms of sacubitril and valsartan, sodium cations, and water molecules in the molar ratio of 1:1:3:2.5, respectively. Following oral administration, the complex dissociates into sacubitril (which is further metabolized to LBQ657) and valsartan. The complex is chemically described as Octadecasodiumhexakis(4-{[(1S,3R)-1-([1,1´-biphenyl]-4-ylmethyl)-4-ethoxy-3-methyl-4-oxobutyl]amino}-4-oxobutanoate)hexakis(N-pentanoyl-N-{[2´-(1H-tetrazol-1-id-5-yl)[1,1´-biphenyl]-4-yl]methyl}-L-valinate)—water (1/15).
Its empirical formula (hemipentahydrate) is C48H55N6O8Na3 2.5 H2O. Its molecular mass is 957.99 and its schematic structural formula is:
Entresto is available as film-coated tablets for oral administration, containing 24 mg of sacubitril and 26 mg of valsartan; 49 mg of sacubitril and 51 mg of valsartan; and 97 mg of sacubitril and 103 mg of valsartan. The tablet inactive ingredients are microcrystalline cellulose, low-substituted hydroxypropylcellulose, crospovidone, magnesium stearate (vegetable origin), talc, and colloidal silicon dioxide. The film-coat inactive ingredients are hypromellose, titanium dioxide (E 171), Macrogol 4000, talc, and iron oxide red (E 172). The film-coat for the 24 mg of sacubitril and 26 mg of valsartan tablet and the 97 mg of sacubitril and 103 mg of valsartan tablet also contains iron oxide black (E 172). The film-coat for the 49 mg of sacubitril and 51 mg of valsartan tablet contains iron oxide yellow (E 172).
CLINICAL PHARMACOLOGY Mechanism of Action
Entresto contains a neprilysin inhibitor, sacubitril, and an angiotensin receptor blocker, valsartan. Entresto inhibits neprilysin (neutral endopeptidase; NEP) via LBQ657, the active metabolite of the prodrug sacubitril, and blocks the angiotensin II type-1 (AT1) receptor via valsartan. The cardiovascular and renal effects of Entresto in heart failure patients are attributed to the increased levels of peptides that are degraded by neprilysin, such as natriuretic peptides, by LBQ657, and the simultaneous inhibition of the effects of angiotensin II by valsartan. Valsartan inhibits the effects of angiotensin II by selectively blocking the AT1 receptor, and also inhibits angiotensin II-dependent aldosterone release.
Pharmacodynamics
The pharmacodynamic effects of Entresto were evaluated after single and multiple dose administrations in healthy subjects and in patients with heart failure, and are consistent with simultaneous neprilysin inhibition and renin-angiotensin system blockade. In a 7-day valsartan-controlled study in patients with reduced ejection fraction (HFrEF), administration of Entresto resulted in a significant non-sustained increase in natriuresis, increased urine cGMP, and decreased plasma MR-proANP and NT-proBNP compared to valsartan.
In a 21-day study in HFrEF patients, Entresto significantly increased urine ANP and cGMP and plasma cGMP, and decreased plasma NT-proBNP, aldosterone and endothelin-1. Entresto also blocked the AT1-receptor as evidenced by increased plasma renin activity and plasma renin concentrations. In PARADIGM-HF, Entresto decreased plasma NT-proBNP (not a neprilysin substrate) and increased plasma BNP (a neprilysin substrate) and urine cGMP compared with enalapril.
QT Prolongation: In a thorough QTc clinical study in healthy male subjects, single doses of Entresto 194 mg sacubitril/206 mg valsartan and 583 mg sacubitril/617 mg valsartan had no effect on cardiac repolarization.
Amyloid-β: Neprilysin is one of multiple enzymes involved in the clearance of amyloid-β (Aβ) from the brain and cerebrospinal fluid (CSF). Administration of Entresto 194 mg sacubitril/206 mg valsartan once-daily for 2 weeks to healthy subjects was associated with an increase in CSF Aβ1-38 compared to placebo; there were no changes in concentrations of CSF Aβ1-40 or CSF Aβ1-42. The clinical relevance of this finding is unknown [see Nonclinical Toxicology (13)].
Blood Pressure: Addition of a 50 mg single dose of sildenafil to Entresto at steady state (194 mg sacubitril/206 mg valsartan once daily for 5 days) in patients with hypertension was associated with additional blood pressure (BP) reduction (~ 5/4 mmHg, systolic/diastolic BP) compared to administration of Entresto alone.
Co-administration of Entresto did not significantly alter the BP effect of intravenous nitroglycerin.
Pharmacokinetics
Absorption
Following oral administration, Entresto dissociates into sacubitril and valsartan. Sacubitril is further metabolized to LBQ657. The peak plasma concentrations of sacubitril, LBQ657, and valsartan are reached in 0.5 hours, 2 hours, and 1.5 hours, respectively. The oral absolute bioavailability of sacubitril is estimated to be ≥ 60%. The valsartan in Entresto is more bioavailable than the valsartan in other marketed tablet formulations; 26 mg, 51 mg, and 103 mg of valsartan in Entresto is equivalent to 40 mg, 80 mg, and 160 mg of valsartan in other marketed tablet formulations, respectively.
Following twice-daily dosing of Entresto, steady state levels of sacubitril, LBQ657, and valsartan are reached in 3 days. At steady state, sacubitril and valsartan do not accumulate significantly, whereas LBQ657 accumulates by 1.6-fold. Entresto administration with food has no clinically significant effect on the systemic exposures of sacubitril, LBQ657, or valsartan. Although there is a decrease in exposure to valsartan when Entresto is administered with food, this decrease is not accompanied by a clinically significant reduction in the therapeutic effect. Entresto can therefore be administered with or without food.
Distribution
Sacubitril, LBQ657 and valsartan are highly bound to plasma proteins (94% to 97%). Based on the comparison of plasma and CSF exposures, LBQ657 crosses the blood brain barrier to a limited extent (0.28%). The average apparent volumes of distribution of valsartan and sacubitril are 75 and 103 L, respectively.
Metabolism
Sacubitril is readily converted to LBQ657 by esterases; LBQ657 is not further metabolized to a significant extent. Valsartan is minimally metabolized; only about 20% of the dose is recovered as metabolites. A hydroxyl metabolite has been identified in plasma at low concentrations (< 10%).
Elimination
Following oral administration, 52% to 68% of sacubitril (primarily as LBQ657) and ~ 13% of valsartan and its metabolites are excreted in urine; 37% to 48% of sacubitril (primarily as LBQ657), and 86% of valsartan and its metabolites are excreted in feces. Sacubitril, LBQ657, and valsartan are eliminated from plasma with a mean elimination half-life (T1/2) of approximately 1.4 hours, 11.5 hours, and 9.9 hours, respectively.
Linearity/Nonlinearity
The pharmacokinetics of sacubitril, LBQ657, and valsartan were linear over an Entresto dose range of 24 mg sacubitril/26 mg valsartan to 194 mg sacubitril/206 mg valsartan.
Drug Interactions:
Effect of Co-administered Drugs on Entresto:
Because CYP450 enzyme-mediated metabolism of sacubitril and valsartan is minimal, coadministration with drugs that impact CYP450 enzymes is not expected to affect the pharmacokinetics of Entresto. Dedicated drug interaction studies demonstrated that coadministration of furosemide, warfarin, digoxin, carvedilol, a combination of levonorgestrel/ethinyl estradiol, amlodipine, omeprazole, hydrochlorothiazide (HCTZ), metformin, atorvastatin, and sildenafil, did not alter the systemic exposure to sacubitril, LBQ657 or valsartan.
Effect of Entresto on Co-administered Drugs:
In vitro data indicate that sacubitril inhibits OATP1B1 and OATP1B3 transporters. The effects of Entresto on the pharmacokinetics of coadministered drugs are summarized in Figure 1.

NONCLINICAL TOXICOLOGY Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenesis and Mutagenesis
Carcinogenicity studies conducted in mice and rats with sacubitril and valsartan did not identify any carcinogenic potential for Entresto. The LBQ657 Cmax at the high dose (HD) of 1200 mg/kg/day in male and female mice was, respectively, 14 and 16 times that in humans at the MRHD. The LBQ657 Cmax in male and female rats at the HD of 400 mg/kg/day was, respectively, 1.7 and 3.5 times that at the MRHD. The doses of valsartan studied (high dose of 160 and 200 mg/kg/day in mice and rats, respectively) were about 4 and 10 times, respectively, the MRHD on a mg/m2 basis.
Mutagenicity and clastogenicity studies conducted with Entresto, sacubitril, and valsartan did not reveal any effects at either the gene or chromosome level.
Impairment of Fertility
Entresto did not show any effects on fertility in rats up to a dose of 73 mg sacubitril/77 mg valsartan/kg/day (≤ 1.0-fold and ≤ 0.18-fold the MRHD on the basis of the AUCs of valsartan and LBQ657, respectively).
Animal Toxicology and/or Pharmacology
The effects of Entresto on amyloid-β concentrations in CSF and brain tissue were assessed in young (2 to 4 years old) cynomolgus monkeys treated with Entresto (24 mg sacubitril/26 mg valsartan/kg/day) for 2 weeks. In this study, Entresto affected CSF Aβ clearance, increasing CSF Aβ 1-40, 1-42, and 1-38 levels in CSF; there was no corresponding increase in Aβ levels in the brain. In addition, in a toxicology study in cynomolgus monkeys treated with Entresto at 146 mg sacubitril/154 mg valsartan/kg/day for 39-weeks, there was no amyloid-β accumulation in the brain.
CLINICAL STUDIES
Dosing in clinical trials was based on the total amount of both components of Entresto, i.e., 24/26 mg, 49/51 mg and 97/103 mg were referred to as 50 mg, 100 mg, and 200 mg, respectively.
PARADIGM-HF
PARADIGM-HF was a multinational, randomized, double-blind trial comparing Entresto and enalapril in 8,442 adult patients with symptomatic chronic heart failure (NYHA class II–IV) and systolic dysfunction (left ventricular ejection fraction ≤ 40%). Patients had to have been on an ACE inhibitor or ARB for at least four weeks and on maximally tolerated doses of beta-blockers. Patients with a systolic blood pressure of < 100 mmHg at screening were excluded.
The primary objective of PARADIGM-HF was to determine whether Entresto, a combination of sacubitril and a RAS inhibitor (valsartan), was superior to a RAS inhibitor (enalapril) alone in reducing the risk of the combined endpoint of cardiovascular (CV) death or hospitalization for heart failure (HF).
After discontinuing their existing ACE inhibitor or ARB therapy, patients entered sequential single-blind run-in periods during which they received enalapril 10 mg twice-daily, followed by Entresto 100 mg twice-daily, increasing to 200 mg twice-daily. Patients who successfully completed the sequential run-in periods were randomized to receive either Entresto 200 mg (N = 4,209) twice-daily or enalapril 10 mg (N = 4,233) twice-daily. The primary endpoint was the first event in the composite of CV death or hospitalization for HF. The median follow-up duration was 27 months and patients were treated for up to 4.3 years.
The population was 66% Caucasian, 18% Asian, and 5% Black; the mean age was 64 years and 78% were male. At randomization, 70% of patients were NYHA Class II, 24% were NYHA Class III, and 0.7% were NYHA Class IV. The mean left ventricular ejection fraction was 29%. The underlying cause of heart failure was coronary artery disease in 60% of patients; 71% had a history of hypertension, 43% had a history of myocardial infarction, 37% had an eGFR < 60 mL/min/1.73m2, and 35% had diabetes mellitus. Most patients were taking beta-blockers (94%), mineralocorticoid antagonists (58%), and diuretics (82%). Few patients had an implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D) (15%).
PARADIGM-HF demonstrated that Entresto, a combination of sacubitril and a RAS inhibitor (valsartan), was superior to a RAS inhibitor (enalapril), in reducing the risk of the combined endpoint of cardiovascular death or hospitalization for heart failure, based on a time-to-event analysis (hazard ratio [HR]: 0.80, 95% confidence interval [CI], 0.73, 0.87, p < 0.0001). The treatment effect reflected a reduction in both cardiovascular death and heart failure hospitalization; see Table 2 and Figure 3. Sudden death accounted for 45% of cardiovascular deaths, followed by pump failure, which accounted for 26%.
Entresto also improved overall survival (HR 0.84; 95% CI [0.76, 0.93], p = 0.0009) (Table 2). This finding was driven entirely by a lower incidence of cardiovascular mortality on Entresto.
