TRYVIO

Clinical summary

Indications and usage 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) ] . Warnings and cautions 5 WARNINGS AND PRECAUTIONS ERAs cause hepatotoxicity and liver failure. Measure serum aminotransferase levels and total bilirubin prior to initiation of treatment and repeat periodically during treatment and as clinically indicated. ( 5.2 ) Fluid retention may require intervention ( 5.3 ) Decreases in hemoglobin ( 5.4 ) Decreased sperm counts ( 5.5 ) 5.1 Embryo-Fetal Toxicity Based on data from animal reproduction studies with endothelin receptor antagonists (ERAs), TRYVIO may cause fetal harm when administered during pregnancy and is contraindicated for use in patients who are pregnant. The available human data for endothelin receptor antagonists do not establish the presence or absence of fetal harm related to the use of TRYVIO. Counsel patients who can become pregnant about the potential risk to a fetus. Obtain a pregnancy test prior to initiation of treatment with TRYVIO. Advise patients who can become pregnant to use effective contraception prior to initiation of treatment with TRYVIO, during treatment, and for one month after the final dose of TRYVIO. When pregnancy is detected, discontinue TRYVIO as soon as possible [see Dosage and Administration (2.2) , Contraindications (4.1) , Use in Specific Populations (8.1 , 8.3) ] . 5.2 Hepatotoxicity Elevations of aminotransferases and hepatotoxicity are known effects of ERAs, including TRYVIO. Elevations in alanine transaminase (ALT) or aspartate aminotransferase (AST) of greater than 5-fold upper limit of normal (ULN) were observed rarely in patients treated with aprocitentan in the clinical trial, including cases with positive rechallenge.
