What is Opsynvi?

From the FDA label:OPSYNVI ® is a single tablet combination containing two oral components used to treat pulmonary arterial hypertension: macitentan, an endothelin receptor antagonist (ERA), and tadalafil, a phosphodiesterase 5 (PDE5) inhibitor. Macitentan Macitentan is an endothelin receptor antagonist. The chemical name of macitentan is N-[5-(4-Bromophenyl)-6-[2-[(5-bromo-2-pyrimidinyl)oxy]ethoxy]-4- pyrimidinyl]-N'-propylsulfamide. It has a molecular formula of C 19 H 20 Br 2 N 6 O 4 S and a molecular weight of 588.27. Macitentan is achiral and has the following structural formula: Macitentan is a crystalline powder that is insoluble in water. In the solid state macitentan is very stable, is not hygroscopic, and is not light sensitive. Chemical Structure Tadalafil Tadalafil, an oral treatment for pulmonary arterial hypertension, is a selective inhibitor of cyclic guanosine monophosphate (cGMP)–specific phosphodiesterase type 5 (PDE5). Tadalafil has the empirical formula C 22 H 19 N 3 O 4 representing a molecular weight of 389.41. The structural formula is: The chemical designation is pyrazino[1´,2´:1,6]pyrido[3,4–b]indole-1,4-dione, 6-(1,3- benzodioxol-5-yl)-2,3,6,7,12,12a-hexahydro-2-methyl-, (6R,12aR)-. It is a crystalline solid that is practically insoluble in water and very slightly soluble in ethanol. Chemical Structure OPSYNVI OPSYNVI is available as 10 mg/20 mg macitentan/tadalafil and…

How to use

One 10 mg/20 mg or 10 mg/40 mg tablet taken orally once daily with or without food. ( 2.1 ) 2.1 Recommended Dosage OPSYNVI is taken orally once daily with or without food. Swallow the tablets whole, with water. Do not cut, crush, or chew tablets. If the patient misses a dose of OPSYNVI, tell the patient to take it as soon as possible and then take the next dose at the regularly scheduled time. Tell the patient not to take two doses at the same time if a dose has been missed. For patients who are treatment-naïve to any PAH specific therapy or transitioning from ERA monotherapy The recommended starting dose of OPSYNVI is one 10 mg/20 mg tablet taken orally once daily with or without food for one week. If tolerated, up titrate OPSYNVI to one 10 mg/40 mg tablet taken orally once daily with or without food as the maintenance dose. For patients transitioning from PDE5 inhibitor monotherapy or PDE5 inhibitor and ERA therapy in combination The recommended dose of OPSYNVI is one 10 mg/40 mg tablet taken orally once daily. 2.2 Pregnancy Testing in Females of Reproductive Potential Exclude pregnancy before initiating treatment with OPSYNVI in females of reproductive potential [see Boxed Warning , Contraindications (4.1) , Warnings and Precautions (5.1) , and Use in Specific Populations (8.3) ].

FDA Boxed Warning (the FDA’s most serious warning)

Boxed (black-box) warning — from the FDA label

EMBRYO-FETAL TOXICITY OPSYNVI is contraindicated for use during pregnancy because it may cause fetal harm based on animal data [see Contraindications (4.1) , Warnings and Precautions (5.1) , Use in Specific Populations (8.1) ]. Therefore, for females of reproductive potential, exclude pregnancy before the start of treatment with OPSYNVI. Advise use of effective contraception before the initiation of treatment, during treatment, and for one month after stopping treatment with OPSYNVI [see Dosage and Administration (2.2) , Use in Specific Populations (8.3) ]. When pregnancy is detected, discontinue OPSYNVI as soon as possible [see Warnings and Precautions (5.1) ] . WARNING: EMBRYO-FETAL TOXICITY See full prescribing information for complete boxed warning. Based on animal data, OPSYNVI may cause fetal harm if used during pregnancy ( 4.1 , 5.1 , 8.1 ). Females of reproductive potential: exclude pregnancy before start of treatment. Prevent pregnancy prior to initiation of treatment, during treatment and for one month after treatment by using effective methods of contraception ( 2.2 , 8.3 ). When pregnancy is detected, discontinue OPSYNVI as soon as possible ( 5.1 ).

Warnings

Important safety information

Hepatotoxicity: ERAs cause hepatotoxicity and liver failure. Obtain baseline liver enzymes and monitor as clinically indicated. ( 5.2 ) Hypotension: Vasodilatory effects may cause hypotension in susceptible patients. ( 5.3 ) Hemoglobin decrease. ( 5.4 ) Worsening Pulmonary Veno-Occlusive Disease: If pulmonary edema is confirmed, discontinue treatment. ( 5.5 ) Visual Loss: Sudden loss of vision could be a sign of non-arteritic ischemic optic neuropathy (NAION) and may be permanent. ( 5.6 ) Hearing Impairment: Cases of sudden decrease or loss of hearing have been reported in patients taking tadalafil. ( 5.7 ) Fluid Retention: Fluid retention may require intervention. ( 5.8 ) Combination with Other PDE5 Inhibitors: Avoid use with other PDE5 inhibitors. ( 5.9 ) Decreased Sperm Count: Decreases in sperm count have been observed in patients taking ERAs. ( 5.10 ) Prolonged Erection: Advise patients to seek emergency treatment if an erection lasts greater than 4 hours. ( 5.11 ) 5.1 Embryo-fetal Toxicity Based on data from animal reproduction studies, OPSYNVI may cause fetal harm when administered to a pregnant patient and is contraindicated during pregnancy. The available human data for ERAs do not establish the presence or absence of major birth defects related to the use of OPSYNVI. Advise patients who can become pregnant of the potential risk to a fetus. Obtain a pregnancy test prior to initiation of therapy with OPSYNVI. Advise patients who can become pregnant to use effective contraceptive methods prior to initiation of treatment, during treatment, and for one month after discontinuation of treatment with OPSYNVI. When pregnancy is detected, discontinue use as soon as possible [see Dosage and Administration (2.2) , Contraindications (4.1) , and Use in Specific Populations (8.1 , 8.3) ]. 5.2 Hepatotoxicity ERAs have caused elevations of aminotransferases, hepatotoxicity, and liver failure. The incidence of elevated aminotransferases in the double-blind and combined double-blind (DB)/open-label (OL) arms of the study of OPSYNVI in PAH are shown in Table 1. Table 1: Incidence of Elevated Aminotransferases in the A DUE Study OPSYNVI DB (N=107) OPSYNVI DB/OL (N=185) ≥3 × ULN 1.0% 3.4% ≥8 × ULN 1.0% 1.1% The overall incidence of treatment discontinuations for hepatic adverse events in the double-blind and combined double-blind/open-label arms study of OPSYNVI in PAH data were 0.9% and 2.2% respectively. The incidence of elevated aminotransferases in the study of OPSUMIT (macitentan) in PAH is shown in Table 2. Table 2: Incidence of Elevated Aminotransferases in the SERAPHIN Study OPSUMIT 10 mg (N=242) Placebo (N=249) >3 × ULN 3.4% 4.5% >8 × ULN 2.1% 0.4% In the placebo-controlled study of OPSUMIT, discontinuations for hepatic adverse events were 3.3% in the OPSUMIT 10 mg group vs. 1.6% for placebo. Obtain liver enzyme tests prior to initiation of OPSYNVI and repeat during treatment as clinically indicated. Advise patients to report symptoms suggesting hepatic injury (nausea, vomiting, right upper quadrant pain, fatigue, anorexia, jaundice, dark urine, fever, or itching). If clinically relevant aminotransferase elevations occur, or if elevations are accompanied by an increase in bilirubin >2 × ULN, or by clinical symptoms of hepatotoxicity, discontinue OPSYNVI. Consider re-initiation of OPSYNVI when hepatic enzyme levels normalize in patients who have not experienced clinical symptoms of hepatotoxicity. Do not initiate OPSYNVI in patients with elevated aminotransferases (> 3 × upper limit of normal [ULN]) at baseline. Patients with severe hepatic cirrhosis (Child-Pugh Class C) have not been studied, and, therefore, avoid use of OPSYNVI. 5.3 Hypotension OPSYNVI tablets have vasodilatory properties that may result in transient decreases in blood pressure. Prior to prescribing OPSYNVI tablets, carefully consider whether patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects. Patients with pre-existing hypotension, with autonomic dysfunction, with left ventricular outflow obstruction, may be particularly sensitive to the actions of vasodilators [see Clinical Pharmacology (12.2) ]. 5.4 Hemoglobin Decrease Decreases in hemoglobin concentration and hematocrit have occurred following administration of other ERAs and were observed in clinical studies with OPSYNVI and OPSUMIT. These decreases occurred early and stabilized thereafter. In the placebo-controlled study of OPSUMIT in PAH, OPSUMIT 10 mg caused a mean decrease in hemoglobin from baseline to up to 18 months of about 1.0 g/dL compared to no change in the placebo group. A decrease in hemoglobin to below 10.0 g/dL was reported in 8.7% of the OPSUMIT 10 mg group and in 3.4% of the placebo group. Similar results were observed in the trial with OPSYNVI. Decreases in hemoglobin seldom require transfusion. Initiation of OPSYNVI is not recommended in patients with severe anemia. Measure hemoglobin prior to initiation of treatment and repeat during treatment as clinically indicated [see Adverse Reactions (6.1) ]. 5.5 Worsening Pulmonary Veno-Occlusive Disease (PVOD) Pulmonary vasodilators may significantly worsen the cardiovascular status of patients with pulmonary veno-occlusive disease (PVOD). Since there are no clinical data on administration of OPSYNVI tablets to patients with veno-occlusive disease, administration of OPSYNVI tablets to such patients is not recommended. Should signs of pulmonary edema occur when OPSYNVI tablets are administered, the possibility of associated PVOD should be considered. If confirmed, discontinue OPSYNVI. 5.6 Visual Loss Non–arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision, including permanent loss of vision, has been reported postmarketing in temporal association with the use of PDE5 inhibitors, including tadalafil. Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of NAION, including: low cup to disc ratio ("crowded disc"), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia, and smoking. Based on published literature, the annual incidence of NAION is 2.5–11.8 cases per 100,000 in males aged greater than or equal to 50 in the general population. Other risk factors for NAION, such as the presence of "crowded" optic disc, may have contributed to the occurrence of NAION. Patients with known hereditary degenerative retinal disorders, including retinitis pigmentosa, were not included in the clinical trials, and use of OPSYNVI in these patients is not recommended. 5.7 Hearing Impairment Cases of sudden decrease or loss of hearing, which may be accompanied by tinnitus and dizziness, have been reported in patients taking tadalafil. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors. 5.8 Fluid Retention Peripheral edema and fluid retention are known clinical consequences of PAH and known effects of ERAs and heart failure has been reported in patients taking OPSYNVI. In the active-controlled and combined double-blind/open-label arms of the study of OPSYNVI in PAH, the incidence of peripheral edema/fluid retention was 20.6% in the active-controlled and 17.3% in the double-blind/open-label arm [see Adverse Reactions (6.1) ] . In the placebo-controlled study of OPSUMIT in PAH, the incidence of edema was 21.9% in the OPSUMIT 10 mg group and 20.5% in the placebo group. Patients with underlying left ventricular dysfunction may be at particular risk for developing significant fluid retention after initiation of ERA treatment. In a small study of OPSUMIT in patients with pulmonary hypertension because of left ventricular dysfunction, more patients in the OPSUMIT group developed significant fluid retention and had more hospitalizations because of worsening heart failure compared to those randomized to placebo. Postmarketing cases of edema and fluid retention occurring…

Who should not take Opsynvi

Pregnancy ( 4.1 ) Hypersensitivity ( 4.2 ) Concomitant Organic Nitrates ( 4.3 ) Concomitant Guanylate Cyclase (GC) Stimulators ( 4.4 ) 4.1 Pregnancy OPSYNVI may cause fetal harm when administered to a pregnant woman. OPSYNVI is contraindicated in females who are pregnant. Macitentan was consistently shown to have teratogenic effects when administered to animals. If OPSYNVI is used during pregnancy, advise the patient of the potential risk to a fetus [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ] . 4.2 Hypersensitivity OPSYNVI is contraindicated in patients with a history of a hypersensitivity reaction to macitentan, tadalafil, or any component of the product. Hypersensitivity reactions have been reported. Stevens-Johnson syndrome and exfoliative dermatitis have been reported with tadalafil [see Adverse Reactions (6.2) ]. 4.3 Concomitant Organic Nitrates OPSYNVI is contraindicated in patients who are using any form of organic nitrate, either regularly or intermittently. Do not use nitrates within 48 hours of the last dose of OPSYNVI. Tadalafil potentiates the hypotensive effect of nitrates. This potentiation is thought to result from the combined effects of nitrates and tadalafil on the nitric oxide/cGMP pathway [see Clinical Pharmacology (12.2) ]. 4.4 Concomitant Guanylate Cyclase (GC) Stimulators Coadministration of GC stimulators such as riociguat with OPSYNVI is contraindicated. Tadalafil may potentiate the hypotensive effects of GC stimulators.

Overdose — what happens if you take too much

In the event of an overdose, standard supportive measures should be taken, as required. Dialysis is unlikely to be effective because macitentan is highly protein-bound. Macitentan Macitentan has been administered as a single dose of up to and including 600 mg to healthy subjects (60 times the approved dosage). Adverse reactions of headache, nausea and vomiting were observed. Tadalafil Single doses of tadalafil up to 500 mg have been given to healthy male subjects, and multiple daily doses up to 100 mg have been given to male patients with erectile dysfunction. Adverse reactions were similar to those seen at lower doses. Doses greater than 40 mg have not been studied in patients with PAH. Hemodialysis contributes negligibly to tadalafil elimination.

Interactions

Strong CYP3A4 Inducers/Inhibitors: Avoid concomitant use ( 7.2 , 7.3 ) Moderate Dual or Combined CYP3A4 and CYP2C9 Inhibitors: Avoid concomitant use ( 7.4 ) 7.1 Nitrates Administration of nitrates within 48 hours after the last dose of OPSYNVI is contraindicated [see Contraindications (4.3) ] . 7.2 Strong CYP3A4 Inducers Strong inducers of CYP3A4 such as rifampin significantly reduce macitentan exposure. Use of OPSYNVI with strong CYP3A4 inducers should be avoided [see Clinical Pharmacology (12.3) ]. 7.3 Strong CYP3A4 Inhibitors Concomitant use of strong CYP3A4 inhibitors like ketoconazole increase exposure to both macitentan and tadalafil. Avoid concomitant use of OPSYNVI with strong CYP3A4 inhibitors such as ritonavir, ketoconazole and itraconazole. Use other PAH treatment options when strong CYP3A4 inhibitors are needed [see Clinical Pharmacology (12.3) ]. 7.4 Moderate Dual or Combined CYP3A4 and CYP2C9 Inhibitors Concomitant use of moderate dual inhibitors of CYP3A4 and CYP2C9 such as fluconazole is predicted to increase macitentan exposure approximately 4-fold. Avoid concomitant use of OPSYNVI with moderate dual inhibitors of CYP3A4 and CYP2C9 (such as fluconazole and amiodarone) [see Clinical Pharmacology (12.3) ]. Concomitant treatment of both a moderate CYP3A4 inhibitor and moderate CYP2C9 inhibitor with OPSYNVI should also be avoided [see Clinical Pharmacology (12.3) ]. 7.5 Alpha-Blockers PDE5 inhibitors, including tadalafil, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. In patients who are taking alpha 1 blockers, concomitant administration of tadalafil may lead to symptomatic hypotension in some patients. Therefore, the combination of OPSYNVI and doxazosin is not recommended [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.2) ]. 7.6 Antihypertensives PDE5 inhibitors, including tadalafil, are mild systemic vasodilators. Clinical pharmacology studies were conducted to assess the effect of tadalafil on the potentiation of the blood–pressure–lowering effects of selected antihypertensive medications (amlodipine, angiotensin II receptor blockers, bendroflumethiazide, enalapril, and metoprolol). Small reductions in blood pressure occurred following coadministration of tadalafil with these agents compared with placebo [see Clinical Pharmacology (12.2) ]. 7.7 Alcohol Both alcohol and tadalafil, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure–lowering effects of each individual compound may be increased. Substantial consumption of alcohol (e.g., 5 units or greater) in combination with OPSYNVI can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache. Tadalafil (10 mg or 20 mg) did not affect alcohol plasma concentrations and alcohol did not affect tadalafil plasma concentrations [see Clinical Pharmacology (12.2) ].

How long does Macitentan and Tadalafil stay in your body?

The elimination half-life of macitentan and tadalafil is about 16 hours (apparent elimination half-life) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. Macitentan has a longer-lasting ACTIVE metabolite that outlasts the parent: its apparent elimination half-life is approximately 48 hours (vs ~16 hours for macitentan itself). This metabolite matters clinically — at steady state in PAH patients its systemic exposure is about 3 times that of the parent and it contributes roughly 40% of total pharmacologic activity (it is about 20% as potent as the parent in vitro). Special populations: the label states no clinically relevant effect of age, sex, or race on the pharmacokinetics. Severe renal impairment (CrCl 15–29 mL/min) raises exposure to macitentan and its metabolite by ~30% and ~60% respectively; mild/moderate/severe hepatic impairment lowers exposure — in both cases the label deems the change not clinically relevant.
