WARNING
EMBRYO-FETAL TOXICITY
Females of reproductive potential: Exclude pregnancy before the start of treatment. To prevent pregnancy, females of reproductive potential must use effective forms of contraception during treatment and for one month after stopping treatment. Do not administer VERQUVO to a pregnant female because it may cause fetal harm [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, and Use In Specific Populations].
VERQUVO tablets contains vericiguat, a soluble guanylate cyclase stimulator.
The chemical name of vericiguat is methyl {4,6-diamino-2-[5-fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b] pyridin-3-yl] pyrimidin-5-yl} carbamate. The molecular formula is C19H16F2N8O2 and the molecular weight is 426.39 g/mol.
The chemical structure is:
 |
Vericiguat is a white to yellowish powder that is freely soluble in dimethyl sulfoxide; slightly soluble in acetone; very slightly soluble in ethanol, acetonitrile, methanol, and ethyl acetate; and practically insoluble in 2-propanol.
VERQUVO™ is available as film-coated tablets for oral administration, containing 2.5 mg of vericiguat, 5 mg of vericiguat or 10 mg of vericiguat.
The tablet inactive ingredients are croscarmellose sodium, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate.
The film coating contains hypromellose, talc and titanium dioxide. The film coating for the 5 mg of VERQUVO tablet also contains ferric oxide red. The film coating for the 10 mg of VERQUVO tablet also contains ferric oxide yellow.
VERQUVO® is indicated to reduce the risk of cardiovascular death and heart failure (HF) hospitalization following a hospitalization for heart failure or need for outpatient IV diuretics, in adults with symptomatic chronic HF and ejection fraction less than 45% [see Clinical Studies].
The recommended starting dose of VERQUVO is 2.5 mg orally once daily with food.
Double the dose of VERQUVO approximately every 2 weeks to reach the target maintenance dose of 10 mg once daily, as tolerated by the patient.
For patients who are unable to swallow whole tablets, VERQUVO may be crushed and mixed with water immediately before administration [see CLINICAL PHARMACOLOGY].
Obtain a pregnancy test in females of reproductive potential prior to initiating treatment with VERQUVO [see WARNINGS AND PRECAUTIONS and Use In Specific Populations].

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.
VERQUVO was evaluated in VICTORIA, which included 2,519 patients treated with VERQUVO (up to 10 mg once daily). The mean duration of VERQUVO exposure was 1 year, and the maximum duration was 2.6 years [see Clinical Studies]. Table 1 lists adverse drug reactions occurring more commonly with VERQUVO than placebo and in ≥5% of patients treated with VERQUVO in VICTORIA.
Table 1: Adverse Drug Reactions Occurring with VERQUVO in VICTORIA
| Adverse Drug Reaction | VERQUVO % N = 2,519 |
Placebo % N = 2,515 |
| Hypotension | 16 | 15 |
| Anemia | 10 | 7 |
VERQUVO is contraindicated in patients with concomitant use of other soluble guanylate cyclase (sGC) stimulators [see CONTRAINDICATIONS].
Concomitant use of VERQUVO with PDE-5 inhibitors is not recommended because of the potential for hypotension [see CLINICAL PHARMACOLOGY].
Included as part of the "PRECAUTIONS" Section
Based on data from animal reproduction studies, VERQUVO may cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential of the potential risk to a fetus. Obtain a pregnancy test before the start of treatment. Advise females of reproductive potential to use effective contraception during treatment with VERQUVO and for at least one month after the final dose [see DOSAGE AND ADMINISTRATION and Use In Specific Populations].
Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION).
If a dose is missed, it should be taken as soon as the patient remembers on the same day of the missed dose. Patients should not take two doses of VERQUVO on the same day.
Advise pregnant women and females of reproductive potential of the potential risk to a fetus and to inform their healthcare provider of a known or suspected pregnancy. Advise females of reproductive potential to use effective contraception during treatment with VERQUVO and for one month after the final dose [see CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS and Use In Specific Populations].
Advise women who are exposed to VERQUVO during pregnancy to report their pregnancy to their healthcare provider. Health care providers should report any prenatal exposure to VERQUVO by calling 1- 877-888-4231 or at https://pregnancyreporting.verquvo-us.com. [See Use In Specific Populations].
Advise women not to breastfeed during treatment with VERQUVO [see Use In Specific Populations].
Carcinogenicity was evaluated in 2-year studies conducted in CD1 mice and Wistar rats. Vericiguat did not show a carcinogenic effect in mice dosed up to 150 mg/kg/day (males) or up to 250 mg/kg/day (females). These doses were associated with exposures 41 times (males) or 78 (females) times the human exposure (total AUC) at the MRHD of 10 mg/day.
In the carcinogenicity study in rats, no vericiguat-related tumor or hyperplastic findings were observed at doses up to 20 mg/kg/day, at exposures of 16 (males) and 21 times (females) the human exposure at the MRHD.
Vericiguat was not genotoxic in the in vitro microbial mutagenicity (Ames) assay, the in vitro mouse lymphoma assay and the in vivo rat and mouse micronucleus assay.
There were no effects on fertility, mating performance or early embryonic development when vericiguat was administered to rats at up to 32 times the human exposure (total AUC) at the MRHD.
There is a Pregnancy Surveillance Program that monitors pregnancy outcomes in women exposed to VERQUVO during pregnancy. Health care providers should report any prenatal exposure to VERQUVO by calling 1-877-888-4231 or at https://pregnancyreporting.verquvo-us.com.
Based on data from animal reproduction studies, VERQUVO may cause fetal harm when administered to a pregnant woman and is contraindicated during pregnancy [see CONTRAINDICATIONS]. There are no available data with VERQUVO use in pregnant women. In animal reproduction studies, oral administration of vericiguat to pregnant rabbits during organogenesis, at ≥4 times the human exposure (total AUC) with the maximum recommended human dose (MRHD) of 10 mg, resulted in malformations of the heart and major vessels, as well as increased number of abortions and resorptions (see Animal Data). In a pre/postnatal toxicity study, vericiguat administered orally to rats during gestation through lactation caused maternal toxicity, which resulted in decreased pup body weight gain (≥10 times the MRHD) and increased pup mortality (24 times the MRHD) during the preweaning period (see Animal Data).
The estimated 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 2-4% and 15-20%, respectively.
Animal Data
In an embryo-fetal development study in rabbits, vericiguat was administered orally to pregnant rabbits during the period of organogenesis from gestation day (GD) 6 to 20 at doses of 0.75, 2.5 or 7.5 mg/kg/day. An increased incidence of cardiac ventricular septal defect along with truncus arteriosus communis was observed at ≥2.5 mg/kg/day, which is ≥4 times the human exposure at the MRHD. Maternal toxicity (decreased food consumption and body weight loss), which may have resulted in late spontaneous abortions and resorptions was noted at ≥2.5 mg/kg/day (≥4 times the human exposure at the MRHD). There were no maternal toxicity or abortions/resorptions and no malformations of the heart and major vessels in rabbits at an exposure approximately equivalent to the human exposure at the MRHD.
In a prenatal developmental toxicity study in rats, vericiguat was administered orally to pregnant rats during the period of organogenesis from GD 6 to 17 at doses of 5, 15 or 50 mg/kg/day. No developmental toxicity was observed up to the highest dose (36 times the human exposure [total AUC] at the MRHD). Maternal toxicity (decreased body weight gain and food consumption) was observed at ≥15 mg/kg/day (≥10 times the human exposure at the MRHD). There was no maternal toxicity at 5 mg/kg/day (4 times the human exposure at the MRHD).
In a pre-postnatal development study in rats, vericiguat was administered orally at doses of 7.5, 15 or 30 mg/kg/day from GD 6 through lactation day 21. Maternal toxicity (decreases in food consumption and body weight gain) was observed at all dose levels ≥6 times the human exposure (total AUC) at the MRHD and resulted in decreased pup body weight gain at ≥15 mg/kg/day (≥10 times the human exposure at the MRHD) and pup mortality at 30 mg/kg/day (24 times the MRHD).
[14C]-vericiguat was administered orally to pregnant rats at a dose of 3 mg/kg. Vericiguat-related material was transferred across the placenta, with fetal plasma concentrations of approximately 67% maternal concentrations on GD 19.
There are no data on the presence of vericiguat in human milk, the effects on the breastfed infant, or the effects on milk production. Vericiguat is present in the milk of lactating rats and it is likely that vericiguat or its metabolites are present in human milk (see Data). Because of the potential for serious adverse reactions in breastfed infants from VERQUVO, advise women not to breastfeed during treatment with VERQUVO.
[14C]-vericiguat was administered intravenously to lactating rats at a dose of 1 mg/kg. Vericiguat-related material was excreted into milk at concentrations approximately 12% maternal plasma concentrations on LD 8.
Verify the pregnancy status in females of reproductive potential prior to initiating VERQUVO [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS and Pregnancy].
Females
VERQUVO may cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment and for one month after the final dose [see WARNINGS AND PRECAUTIONS].
Safety and effectiveness of VERQUVO have not been established in pediatric patients.
No dosage adjustment of VERQUVO is required in geriatric patients. In VICTORIA, a total of 1,596 (63%) patients treated with VERQUVO were 65 years and older, and 783 (31%) patients treated with VERQUVO were 75 years and older. No overall differences in safety or efficacy of VERQUVO were observed between patients aged 65 years and older compared to younger patients, but greater sensitivity of some older individuals cannot be ruled out [see CLINICAL PHARMACOLOGY and Clinical Studies].
No dosage adjustment of VERQUVO is recommended in patients with estimated glomerular filtration rate (eGFR) ≥15 mL/min/1.73m2 who are not on dialysis. VERQUVO has not been studied in patients with eGFR <15 mL/min/1.73m2 at treatment initiation or on dialysis [see CLINICAL PHARMACOLOGY and Clinical Studies].
No dosage adjustment of VERQUVO is recommended in patients with mild or moderate hepatic impairment (e.g., Child-Pugh A or B). VERQUVO has not been studied in patients with severe hepatic impairment (e.g., Child-Pugh C) [see CLINICAL PHARMACOLOGY].
Limited data are available with regard to overdosage in human patients treated with VERQUVO. In VICTORIA, doses up to 10 mg have been studied. In a study of patients with preserved ejection fraction heart failure (left ventricular ejection fraction ≥45%), multiple doses of VERQUVO 15 mg have been studied and were generally well tolerated. In the event of an overdose, hypotension may result. Symptomatic treatment should be provided. VERQUVO is unlikely to be removed by hemodialysis because of high protein binding.
VERQUVO is contraindicated in patients with concomitant use of other soluble guanylate cyclase (sGC) stimulators [see DRUG INTERACTIONS].
VERQUVO is contraindicated in pregnancy [see WARNINGS AND PRECAUTIONS and Use In Specific Populations].
Vericiguat is a stimulator of soluble guanylate cyclase (sGC), an important enzyme in the nitric oxide (NO) signaling pathway. When NO binds to sGC, the enzyme catalyzes the synthesis of intracellular cyclic guanosine monophosphate (cGMP), a second messenger that plays a role in the regulation of vascular tone, cardiac contractility, and cardiac remodeling. Heart failure is associated with impaired synthesis of NO and decreased activity of sGC, which may contribute to myocardial and vascular dysfunction. By directly stimulating sGC, independently of and synergistically with NO, vericiguat augments levels of intracellular cGMP, leading to smooth muscle relaxation and vasodilation.
The mean reduction in systolic blood pressure was approximately 1 to 2 mm Hg greater in patients who received VERQUVO compared with placebo.
VERQUVO demonstrated a dose-dependent reduction in NT-proBNP, a biomarker in heart failure, at 12 weeks compared to placebo when added to standard of care. The estimated reduction from baseline NTproBNP at week 32 was greater in patients who received VERQUVO compared with placebo [see Clinical Studies].
There was no evidence of proarrhythmic risk in an in vitro assessment of vericiguat or its major Nglucuronide metabolite. No inhibition of cardiac ion channels (hERG, hNav1.5, or hKvLQT1/mink) was observed at substantial multiples of their unbound Cmax values at the recommended target dose of 10 mg.
The integrated risk assessment of nonclinical and clinical data supports that administration of vericiguat 10 mg is not associated with clinically meaningful QTc prolongation.
No clinically significant differences on bleeding time or platelet aggregation were observed when a single dose of vericiguat 15 mg was used concomitantly with 500 mg of aspirin.
No clinically significant differences in prothrombin time or the activities of Factors II, VII, and X were observed when multiple doses of VERQUVO 10 mg once daily were used concomitantly with a single dose of warfarin 25 mg.
No clinically significant differences on seated blood pressure (BP) were observed when multiple doses of VERQUVO 2.5 mg were used concomitantly with sacubitril/valsartan in healthy subjects.
No clinically significant differences on seated BP were observed when multiple doses of VERQUVO 10 mg were used concomitantly with short- and long-acting nitrates (nitroglycerin spray and isosorbide mononitrate [ISMN] modified release 60 mg) in patients with coronary artery disease. In patients with heart failure, concomitant use with short-acting nitrates was well tolerated, but there is limited experience with long-acting nitrates.
Concomitant use of VERQUVO 10 mg with single doses of sildenafil (25, 50, or 100 mg) was associated with additional seated BP reduction of up to 5.4 mm Hg (systolic/diastolic BP, MAP), compared to administration of VERQUVO alone. There is limited experience with concomitant use of VERQUVO and PDE-5 inhibitors in patients with heart failure.
Vericiguat steady-state mean (coefficient of variation %) Cmax is 350 mcg/L (29%) and AUC is 6,680 mcgh/L (33.9%) following administration of VERQUVO 10 mg in patients with heart failure. Vericiguat 7 pharmacokinetics increases in a slightly less than dose-proportional manner. Vericiguat accumulates in plasma up to 155-171% and reaches steady-state after approximately 6 days.
The absolute bioavailability of vericiguat is 93% when taken with food. Results were comparable when VERQUVO was administered orally as a whole tablet or as a crushed tablet in water.
Effect of Food
Administration of VERQUVO 10 mg with a high-fat, high-calorie meal increases Tmax from about 1 hour (fasted) to about 4 hours (fed), reduces PK variability, and increases vericiguat AUC by 44% and Cmax by 41% compared with administration in the fasted state. Similar results were obtained when VERQUVO was administered with a low-fat, low-calorie meal when compared to administration with a high-fat, high-calorie meal.
The mean steady-state volume of distribution of vericiguat is approximately 44 L in healthy subjects. Protein binding (primarily to serum albumin) of vericiguat is about 98%.
The half-life of vericiguat is 30 hours in patients with heart failure. Clearance in healthy subjects is 1.6 L/h.
Metabolism
Vericiguat primarily undergoes glucuronidation by UGT1A9 and to a lesser extent, by UGT1A1 to form an inactive N-glucuronide metabolite. CYP-mediated metabolism is a minor clearance pathway (<5%).
Excretion
Following oral administration of radiolabeled vericiguat to healthy subjects, approximately 53% of the dose was excreted in urine (primarily as inactive metabolite) and 45% in feces (primarily as unchanged drug).
In patients with heart failure with mild, moderate, and severe renal impairment not requiring dialysis, the mean exposure (AUC) of vericiguat was increased by 5%, 13%, and 20% respectively, compared to patients with normal renal function. These differences in exposure are not considered clinically relevant. The pharmacokinetics of vericiguat have not been studied in patients with eGFR <15 mL/min/1.73m2 at treatment initiation or on dialysis [see Use In Specific Populations].
In a dedicated clinical pharmacology study, otherwise healthy participants with mild, moderate, and severe renal impairment, had 8%, 73%, and 143% respectively, higher mean vericiguat exposure (unbound AUC normalized for body weight) after a single dose compared to healthy controls.
The apparent discrepancy of the effect of renal impairment on vericiguat exposure between the dedicated clinical pharmacology study and the analysis in patients with heart failure may be attributed to differences in study design and size.
No clinically relevant increases in exposure (unbound AUC normalized for body weight) were observed for individuals with mild and moderate hepatic impairment (Child Pugh A-B). Mean vericiguat exposures were 21% and 47% higher, respectively, compared to individuals with normal hepatic function. The pharmacokinetics of vericiguat have not been studied in patients with severe hepatic impairment (e.g., Child-Pugh C) [see Use In Specific Populations].
No clinically significant differences in the pharmacokinetics of vericiguat were observed based on age, sex, race/ethnicity (Black, White, Asian, Hispanic, Latino), body weight, or baseline NT-proBNP. Effects of specific populations on the pharmacokinetics of vericiguat are shown in Figure 1.
Figure 1: Pharmacokinetics of Vericiguat in Specific Populations

Effects of Other Drugs on the Pharmacokinetics of Vericiguat
Vericiguat is less soluble at neutral than at acidic pH. Pre- and co-treatment with drugs that increase gastric pH, such as proton pump inhibitors or antacids, decrease vericiguat exposure (AUC) by about 30% following fasted administration. However, co-treatment with drugs that increase gastric pH did not affect vericiguat exposure in patients with heart failure when vericiguat was taken as directed with food.
No clinically significant differences on vericiguat pharmacokinetics were observed with co-administration of mefenamic acid (UGT1A9 inhibitor), ketoconazole (multi-pathway CYP and transporter inhibitor), rifampin (inducer), digoxin (P-gp substrate), warfarin, aspirin, sildenafil, or the combination of sacubitril/valsartan in healthy subjects. No clinically significant differences on vericiguat pharmacokinetics were predicted with coadministration of atazanavir (UGT1A1 inhibitor).
Effects of Vericiguat on the Pharmacokinetics of Other Drugs
No clinically significant differences on the pharmacokinetics of midazolam (CYP3A substrate), digoxin (Pgp substrate), warfarin, sildenafil, or the combination of sacubitril (including metabolite LBQ657)/valsartan were observed when coadministered with VERQUVO in healthy subjects.
In Vitro Studies
Cytochrome P450 (CYP) enzymes: vericiguat is not an inhibitor of CYP1A2, 2B6, 2C8, 2C9, 2C19, or 2D6, 3A4 and is not an inducer of CYP1A2, 2B6, or 3A4.
Uridine diphosphate (UDP)-glucuronosyl transferase (UGT) enzymes: vericiguat is not an inhibitor of UGT1A1, 1A4, 1A6, 1A9, 2B4, or 2B7.
Transporter systems: vericiguat is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) but is not a substrate of organic cation transporter (OCT1) or organic anion transporting polypeptides (OATP1B1 and OATP1B3). Vericiguat is not an inhibitor of P-gp, BCRP, BSEP, OATP1B1/1B3, OAT1, OAT3, OCT1, OCT2, MATE1, or MATE2K.
In growing rats, reversible effects on bone formation were observed, consisting of hypertrophy of growth plate and hyperostosis and remodeling of metaphyseal and diaphyseal bone. These effects were not observed after chronic administration of vericiguat at up to 22X (adult male rats), 25X (adult female rats), and 2.4X (adult dogs) the human exposure (total AUC) at the MRHD [see Use In Specific Populations].
VICTORIA was a randomized, parallel-group, placebo-controlled, double-blind, event-driven, multi-center trial comparing VERQUVO and placebo in 5,050 adult patients with symptomatic chronic heart failure (New York Heart Association [NYHA] class II-IV) and left ventricular ejection fraction (LVEF) less than 45% following a worsening heart failure event. A worsening heart failure event was defined as heart failure hospitalization within 6 months before randomization or use of outpatient IV diuretics for heart failure within 3 months before randomization.
Patients were randomized to receive VERQUVO 10 mg or matching placebo. VERQUVO was initiated at 2.5 mg once daily and increased at approximately 2 week intervals to 5 mg once daily and the target dose of 10 mg once daily, as tolerated. Placebo doses were similarly adjusted. After approximately 1 year, 90% of patients in both treatment groups were treated with the 10 mg target dose.
The primary endpoint was a composite of time to first event of CV death or hospitalization for heart failure. The median follow-up for the primary endpoint was 11 months.
The population was 64% Caucasian, 22% Asian, and 5% Black. The mean age was 67 years and 76% were male. At randomization, 59% of patients were NYHA Class II, 40% were NYHA Class III, and 1% were NYHA Class IV. The mean left ventricular ejection fraction (EF) was 29%. Approximately half of all patients had an EF <30%, and 14% had an EF between 40% and 45%. The most frequently reported medical history conditions other than heart failure included hypertension (79%), coronary artery disease (58%), hyperlipidemia (57%), diabetes mellitus (47%), atrial fibrillation (45%) and myocardial infarction (42%). At randomization, the mean eGFR was 62 mL/min/1.73 m2; the majority of patients (88%) had an eGFR >30 mL/min/1.73 m2. Sixty-seven percent of the patients were enrolled within 3 months of a HF-hospitalization index event; 17% were enrolled within 3 to 6 months of HF hospitalization, and 16% were enrolled within 3 months of outpatient treatment with IV diuretics for worsening HF. The median NT-proBNP level was 2800 pg/mL at randomization.
At baseline, 93% of patients were on a beta blocker, 73% of patients were on an angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB), 70% of patients were on a mineralocorticoid receptor antagonist (MRA), 15% of patients were on a combination of an angiotensin receptor and neprilysin inhibitor (ARNI), 28% of patients had an implantable cardiac defibrillator, and 15% had a biventricular pacemaker. Ninety-one percent of patients were treated with 2 or more heart failure medications (beta blocker, any renin-angiotensin system [RAS] inhibitor or MRA) and 60% of patients were treated with all 3. At baseline, 6% of patients were on ivabradine and 3% of patients were on a sodium glucose co-transporter 2 (SGLT2) inhibitor.
In VICTORIA, VERQUVO was superior to placebo in reducing the risk of CV death or heart failure hospitalization based on a time-to-event analysis (hazard ratio [HR]: 0.90, 95% confidence interval [CI], 0.82-0.98; p=0.019). Over the course of the study, there was a 4.2% annualized absolute risk reduction (ARR) with VERQUVO compared with placebo. The treatment effect reflected a reduction in both cardiovascular death and heart failure hospitalization (see Table 2).

A wide range of demographic characteristics, baseline disease characteristics, and baseline concomitant medications were examined for their influence on outcomes. The results of the prespecified subgroup analysis for the primary composite endpoint are shown in Figure 3.
Figure 3: Primary Composite Endpoint (CV Death or HF Hospitalization) – Subgroup Analysis
 |
As shown above in Figure 3, the results of the primary composite endpoint were generally consistent across subgroups. However, among patients in the highest baseline NT-proBNP quartile, the estimated HRs for both CV death (HR: 1.16; 95% CI: [0.95, 1.43]) and first HF hospitalization (HR:1.19; 95%CI: [0.9,1.44]) were unfavorable, in contrast to the estimated HRs for patients in the three quartiles with lower NT-proBNP levels.
Secondary endpoints other than the components of the primary endpoint were tested according to a hierarchical testing procedure to control the family wise type I error rate. VERQUVO was superior to placebo in reducing the risk of total (first and recurrent) events of HF hospitalization and the first occurrence of either all-cause mortality or HF hospitalization (see Table 3).
