Sacubitril And Valsartan

1 INDICATIONS AND USAGE ENTRESTO is a combination of sacubitril, a neprilisin inhibitor, and valsartan, an angiotensin II receptor blocker, and is indicated: to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure. Benefits are most clearly evident in patients with left ventricular ejection fraction (LVEF) below normal. ( 1.1 ) for the treatment of symptomatic heart failure with systemic left ventricular systolic dysfunction in pediatric patients aged one year and older. ENTRESTO reduces NT-proBNP and is expected to improve cardiovascular outcomes. ( 1.2 ) 1.1 Adult Heart Failure ENTRESTO is indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure. Benefits are most clearly evident in patients with left ventricular ejection fraction (LVEF) below normal. LVEF is a variable measure, so use clinical judgment in deciding whom to treat [see Clinical Studies (14.1)] . 1.2 Pediatric Heart Failure ENTRESTO is indicated for the treatment of symptomatic heart failure with systemic left ventricular systolic dysfunction in pediatric patients aged one year and older. ENTRESTO reduces NT-proBNP and is expected to improve cardiovascular outcomes.

2 DOSAGE AND ADMINISTRATION The recommended starting dosage for adults is 49 mg/51 mg orally twice daily. The target maintenance dose is 97 mg/103mg orally twice daily. ( 2.2 ) Adjust adult doses every 2 to 4 weeks to the target maintenance dose, as tolerated by the patient. ( 2.2 ) For pediatric patients, see the Full Prescribing Information for recommended dosage, titrations, preparation and administration instructions. ( 2.3 , 2.4 , 2.5 ) Reduce starting dose to half the usually recommended starting dosage for: patients not currently taking an angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB) or previously taking a low dose of these agents. ( 2.6 ) patients with severe renal impairment. ( 2.7 ) patients with moderate hepatic impairment. ( 2.8 ) 2.1 General Considerations 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)] . 2.2 Adult Heart Failure The recommended starting dose of ENTRESTO is 49/51 mg orally 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. 2.3 Pediatric Heart Failure For the recommended dosage for pediatric patients aged 1 year and older, refer to Table 1 if using the tablets, or Table 2 if using the oral pellets. Take the recommended dose orally twice daily. Adjust pediatric patient doses every 2 weeks, as tolerated by the patient.

ENTRESTO 800 mg/200 mL oral suspension can be prepared in a concentration of 4 mg/mL (sacubitril/valsartan 1.96/2.04 mg/mL). Use ENTRESTO 49/51 mg tablets in the preparation of the suspension. To make an 800 mg/200 mL (4 mg/mL) oral suspension, transfer eight tablets of ENTRESTO 49/51 mg film-coated tablets into a mortar. Crush the tablets into a fine powder using a pestle. Add 60 mL of Ora-Plus ® into the mortar and triturate gently with pestle for 10 minutes, to form a uniform suspension. Add 140 mL of Ora-Sweet ® SF into mortar and triturate with pestle for another 10 minutes, to form a uniform suspension. Transfer the entire contents from the mortar into a clean 200 mL amber colored PET or glass bottle. Place a press-in bottle adapter and close the bottle with a child resistant cap. The oral suspension can be stored for up to 15 days. Do not store above 25°C (77°F) and do not refrigerate. Shake before each use. * Ora-Sweet SF ® and Ora-Plus ® are registered trademarks of Paddock Laboratories, Inc. 2.5 Preparation and Administration of Oral Pellets ENTRESTO SPRINKLE are oral pellets contained within capsules. Do not swallow the capsules. Do not chew or crush the oral pellets. ENTRESTO SPRINKLE can also be substituted in patients unable to swallow tablets. Use the entire contents of the capsules to achieve the dose. To administer ENTRESTO oral pellets, open the capsule and sprinkle the full content onto 1 to 2 teaspoons of soft food. Consume the food containing the oral pellets immediately after adding them. Empty capsule shells must be discarded after use and not swallowed. Do not administer ENTRESTO oral pellets via nasogastric, gastrostomy, or other enteral tubes because it may cause obstruction of enteral tubes. 2.6 Dose Adjustment for Patients Not Taking an ACE inhibitor or ARB or Previously Taking Low Doses of These Agents In patients not currently taking an ACE inhibitor or an angiotensin II receptor blocker (ARB) and for patients previously taking low doses of these agents, start ENTRESTO at half the usually recommended starting dose. After initiation, increase the dose every 2 to 4 weeks in adults and every 2 weeks in pediatric patients to follow the recommended dose escalation thereafter [see Dosage and Administration (2.2, 2.3)] . Note: Initiate pediatric patients weighing 40 to 50 kg who meet this criterion at 0.8 mg/kg twice daily using the oral suspension or oral pellets [see Dosage and Administration (2.3, 2.4, 2.5)] . 2.7 Dose Adjustment for Severe Renal Impairment In adults and pediatric patients with severe renal impairment estimated glomerular filtration rate (eGFR less than 30 mL/min/1.73 m 2 ), start ENTRESTO at half the usually recommended starting dose. After initiation, increase the dose to follow the recommended dose escalation thereafter [see Dosage and Administration (2.2, 2.3)] . Note: Initiate pediatric patients weighing 40 to 50 kg who meet this criterion at 0.8 mg/kg twice daily using the oral suspension or oral pellets [see Dosage and Administration (2.3, 2.4, 2.5)] . No starting dose adjustment is needed for mild or moderate renal impairment. 2.8 Dose Adjustment for Hepatic Impairment In adults and pediatric patients with moderate hepatic impairment (Child-Pugh B classification), start ENTRESTO at half the usually recommended starting dose. After initiation, increase the dose to follow the recommended dose escalation thereafter [see Dosage and Administration (2.2, 2.3)] . Note: Initiate pediatric patients weighing 40 to 50 kg who meet this criterion at 0.8 mg/kg twice daily using the oral suspension or oral pellets [see Dosage and Administration (2.3, 2.4, 2.5)] . No starting dose adjustment is needed for mild hepatic impairment. Use in patients with severe hepatic impairment is not recommended.

6 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)] Adverse reactions occurring greater than or equal to 5% are hypotension, hyperkalemia, cough, dizziness, and renal failure. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novartis Pharmaceuticals Corporation at 1-888-669-6682 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. A total of 6,622 heart failure patients were treated with ENTRESTO in the PARADIGM-HF (vs. enalapril) and PARAGON-HF (vs. valsartan) clinical trials. Of these, 5,085 were exposed for at least 1 year. Adult Heart Failure In PARADIGM-HF, patients 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 greater than or equal to 5% in patients who were treated with ENTRESTO in the double-blind period of PARADIGM-HF are shown in Table 3. In PARADIGM-HF, 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. Table 3: Adverse Reactions Reported in greater than or equal to 5% of Patients Treated with ENTRESTO in the Double-Blind Period of PARADIGM-HF ENTRESTO (n = 4,203) % Enalapril (n = 4,229) % Hypotension 18 12 Hyperkalemia 12 14 Cough 9 13 Dizziness 6 5 Renal failure/acute renal failure 5 5 In PARAGON-HF, no new adverse reactions were identified. Pediatric Heart Failure The adverse reactions observed in pediatric patients 1 year to less than 18 years old who received treatment with ENTRESTO were consistent with those observed in adult patients. Laboratory Abnormalities Hemoglobin and Hematocrit Decreases in hemoglobin/hematocrit of greater than 20% were observed in approximately 5% of both ENTRESTO- and enalapril-treated patients in the double-blind period in PARADIGM-HF. Decreases in hemoglobin/hematocrit of greater than 20% were observed in approximately 7% of ENTRESTO-treated patients and 9% of valsartan-treated patients in the double-blind period in PARAGON-HF. Serum Creatinine During the double-blind period in PARADIGM-HF, approximately 16% of both ENTRESTO- and enalapril-treated patients had increases in serum creatinine of greater than 50%. During the double-blind period in PARAGON-HF, approximately 17% of ENTRESTO-treated patients and 21% of valsartan-treated patients had increases in serum creatinine of greater than 50%. Serum Potassium During the double-blind period of PARADIGM-HF, approximately 16% of both ENTRESTO- and enalapril-treated patients had potassium concentrations greater than 5.5 mEq/L. During the double-blind period of PARAGON-HF, approximately 18% of ENTRESTO-treated patients and 20% of valsartan-treated patients had potassium concentrations greater than 5.5 mEq/L. 6.2 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

12.3 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 greater than or equal to 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 (less than 10%). Elimination Following oral administration, 52% to 68% of sacubitril (primarily as LBQ657) and approximately 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 (T 1/2 ) 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. Figure 1: Effect of ENTRESTO on Pharmacokinetics of Coadministered Drugs Specific Populations Effect of specific populations on the pharmacokinetics of LBQ657 and valsartan are shown in Figure 2. Figure 2: Pharmacokinetics of ENTRESTO in Specific Populations Note: Child-Pugh Classification was used for hepatic impairment. Pediatric Patients: The pharmacokinetics of ENTRESTO were evaluated in pediatric heart failure patients 1 to less than 18 years old administered oral doses of 0.8 mg/kg and 3.1 mg/kg of ENTRESTO. Pharmacokinetic data indicated that exposure to ENTRESTO in pediatric and adult patients is similar.
