Chemical Structure

What Is Aprocitentan Used For?

1 INDICATIONS AND USAGE TRYVIO, in combination with other antihypertensive drugs, is indicated for the treatment of hypertension, to lower blood pressure (BP) in adult patients who are not adequately controlled on other drugs. Lowering BP reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes. There are no controlled trials demonstrating reduction of risk of these events with TRYVIO. Control of high BP should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve BP goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program's Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is BP reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher BPs, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from BP reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower BP goal. TRYVIO is an endothelin receptor antagonist indicated for the treatment of hypertension in combination with other antihypertensive drugs, to lower blood pressure in adult patients who are not adequately controlled on other drugs. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. ( 1 )

Dosage and Administration

2 DOSAGE AND ADMINISTRATION The recommended dosage of TRYVIO is 12.5 mg orally once daily, with or without food. ( 2.1 ) 2.1 Recommended Dosage The recommended dosage of TRYVIO is 12.5 mg orally once daily. Swallow tablets whole. TRYVIO may be taken with or without food. If a dose is missed, skip the missed dose and take the next dose at the regular time. Do not take two doses on the same day. 2.2 Pregnancy Testing in Females of Reproductive Potential Exclude pregnancy before initiating treatment with TRYVIO in females of reproductive potential [see Boxed Warning, Contraindications (4.1) , Warnings and Precautions (5.1) , Use in Specific Populations (8.3) ] .

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS Clinically significant adverse reactions that appear in other sections of the labeling include: Embryo-fetal toxicity [see Warnings and Precautions (5.1) ] Hepatotoxicity [see Warnings and Precautions (5.2) ] Fluid retention [see Warnings and Precautions (5.3) ] Hemoglobin decrease [see Warnings and Precautions (5.4) ] Decreased sperm counts [see Warnings and Precautions (5.5) ] Most common adverse reactions (more frequent than placebo and ≥ 2% in TRYVIO-treated patients) are edema/fluid retention and anemia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Idorsia Pharmaceuticals Ltd at 1-833-400-9611 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. The safety of TRYVIO was evaluated in a placebo-controlled phase 3 clinical study (PRECISION, NCT03541174) in adults with uncontrolled BP (systolic blood pressure [SBP] ≥140 mmHg) despite the use of at least three antihypertensive medications. In this study, 724 patients received any dose of aprocitentan, with 633 patients treated for at least 26 weeks, 192 patients for at least 47 weeks, and 99 patients for at least 48 weeks. The most frequently reported adverse reactions to TRYVIO during the 4-week double-blind placebo-controlled treatment period (part 1) of the PRECISION study are presented in Table 1. Table 1 Adverse reactions reported with a frequency of ≥2% in TRYVIO-treated patients and greater (≥1%) than in placebo-treated patients during the initial 4-week double-blind placebo-controlled treatment (part 1) Adverse Reaction 12.5 mg N = 243 % Placebo N = 242 % Edema/fluid retention 9.1 2.1 Anemia 3.7 0 Hypersensitivity Reactions During the initial 4-week double-blind placebo-controlled treatment period (part 1), 0.8% of patients experienced an adverse reaction of hypersensitivity (i.e., rash, erythema, allergic edema) on TRYVIO compared to no reports in patients treated with placebo. One patient experienced allergic dermatitis requiring hospitalization while receiving aprocitentan 25 mg. Laboratory Tests Initiation of TRYVIO may cause an initial small decrease in estimated glomerular filtration rate (eGFR) that occurs within the first 6 weeks of starting therapy and then stabilizes. In the initial 4-week double-blind treatment period, TRYVIO 12.5 mg caused a mean decrease of about 0.8 g/dL in hemoglobin compared to no change in the placebo patients.

Contraindications

4 CONTRAINDICATIONS Pregnancy ( 4.1 ) Hypersensitivity ( 4.2 ) 4.1 Pregnancy Use of TRYVIO is contraindicated in patients who are pregnant [see Dosage and Administration (2.2) , Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ] . 4.2 Hypersensitivity TRYVIO is contraindicated in patients who are hypersensitive to aprocitentan or any of its excipients [see Adverse Reactions (6.1) ] .

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Based on animal reproduction studies with other ERAs, TRYVIO can cause embryo-fetal toxicity, including birth defects and fetal death when administered to a pregnant patient and is contraindicated during pregnancy [see Contraindications (4.1) ] . Available data from post-marketing reports and published literature over decades of use with endothelin receptor antagonists in the same class as TRYVIO have not identified an increased risk of fetal harm; however, these data are limited. Methodological limitations of these post-marketing reports and published literature include lack of a control group; limited information regarding dose, duration, and timing of drug exposure; and missing data. These limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal endothelin receptor antagonist use. Administration of macitentan, where approximately ≥50% of total exposure was to aprocitentan, was teratogenic in rats and rabbits at all doses tested (see Data ). Available data from reports of pregnancy in clinical trials with TRYVIO are insufficient to rule out a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Advise pregnant patients of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In embryo-fetal development toxicity studies in pregnant rats and rabbits given macitentan (for which aprocitentan is a major metabolite) during the period of major organogenesis, cardiovascular and mandibular arch fusion malformations were observed at all doses studied. The lowest doses in rats and...

Overdosage

10 OVERDOSAGE TRYVIO has been administered as a single dose of up to 600 mg, and as multiple doses of up to 100 mg daily, to healthy subjects (48 and 8 times the recommended dose, respectively). Adverse events of headache, nasal congestion, nausea, and upper respiratory tract infection were observed. In the event of an overdose, standard supportive measures should be taken, as required. Dialysis is unlikely to be effective because aprocitentan is highly protein-bound. Consult a Certified Poison Control Center for the most up-to-date information on the management of overdosage (1-800-222-1222 or www.poison.org).
