Vericiguat for the treatment of heart failure: mechanism of action and pharmacological properties compared with other emerging therapeutic options

Vericiguat improves cardiac function and microcirculation of a male patient with Fabry disease: A case report

Fabry disease (FD) is a rare X chromosome-linked disorder and can be easily misdiagnosed. Here, we report the case of a 69-year-old male patient with FD who developed heart failure and showed extremely high pulmonary artery pressure. His initial symptom was recurrent atrial fibrillation. The left and right atrial inner diameters were large, and the ventricular wall was thick. Gene analysis which showed GLA c.215T>C p.Met72Thr mutation and single photon emission computed tomography indicated the diagnosis of FD with coronary microvascular dysfunction. The patient was prescribed anti-heart failure drugs, including vericiguat. Following the treatment, his heart function and microvascular perfusion significantly improved, which might be due to the beneficial effects of vericiguat.

Cost-Utility Analysis of Vericiguat in Heart Failure with Reduced Ejection Fraction After Worsening Heart Failure Events in China

OBJECTIVE

Vericiguat is a new medication to demonstrate clinical efficacy in heart failure with reduced ejection fraction (HFrEF) after worsening heart failure (WHF) events, but its cost-utility was unknown. We aimed to assess the cost-utility of combining the application of vericiguat with standard treatment in HFrEF patients who had WHF events.

METHODS

A multistate Markov model was implemented to mimic the economic results of HFrEF patients who had WHF events in China after receiving vericiguat or placebo. An analysis of cost-utility was conducted; most parameters were set according to the published studies and related databases. All the utilities and costs were decreased at a rate of 5% annually. The incremental cost-effectiveness ratios (ICERs) were the primary outcome measure. We also conducted sensitivity analyses.

RESULTS

Over a 20 year lifetime horizon, additional use of vericiguat led to an elevated cost from US$9725.03 to US$20,660.76 at the current vericiguat costs. This was related to increased quality-adjusted life years (QALYs) from 2.50 to 2.66, along with an ICER of US$65,057.24 per QALY, which was over the willingness-to-pay (WTP) threshold of US$36,096.30 per QALY. If the vericiguat costs were discounted at 80%, it contributed to an ICER of US$12,226.77 per QALY. Additional use of vericiguat for patients with plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) of ≤ 5314 pg per ml produced an ICER of US$23,688.46 per QALY. The outcomes of the one-way sensitivity analysis showed the risk of death from cardiovascular disease in both groups was variable with the highest sensitivity. The probabilistic sensitivity analysis showed that 41.6% of the mimicked population receiving vericiguat combined with standard therapy was cost-effective at the WTP threshold of US$36,096.30 per QALY.

CONCLUSIONS

From the perspective of Chinese public healthcare system, the combined use of vericiguat and standard treatment in patients with HFrEF following WHF events did not generate advantages in cost-utility in China but was a cost-effective therapeutic strategy for those who with plasma NT-proBNP of ≤ 5314 pg per ml.

The sGCa Vericiguat Exhibit Cardioprotective and Anti-Sarcopenic Effects through NLRP-3 Pathways: Potential Benefits for Anthracycline-Treated Cancer Patients

Anthracycline-induced cardiomyopathies and sarcopenia are frequently seen in cancer patients, affecting their overall survival and quality of life; therefore, new cardioprotective and anti-sarcopenic strategies are needed. Vericiguat is a new oral guanylate cyclase activator that reduces heart failure hospitalizations or cardiovascular death. This study highlighted the potential cardioprotective and anti-sarcopenic properties of vericiguat during anthracycline therapy. Human cardiomyocytes and primary skeletal muscle cells were exposed to doxorubicin (DOXO) with or without a pre-treatment with vericiguat. Mitochondrial cell viability, LDH, and Cytochrome C release were performed to study cytoprotective properties. Intracellular Ca++ content, TUNEL assay, cGMP, NLRP-3, Myd-88, and cytokine intracellular levels were quantified through colorimetric and selective ELISA methods. Vericiguat exerts significant cytoprotective and anti-apoptotic effects during exposure to doxorubicin. A drastic increase in cGMP expression and reduction in NLRP-3, MyD-88 levels were also seen in Vericiguat-DOXO groups vs. DOXO groups (p < 0.001) in both cardiomyocytes and human muscle cells. GCa vericiguat reduces cytokines and chemokines involved in heart failure and sarcopenia. The findings that emerged from this study could provide the rationale for further preclinical and clinical investigations aimed at reducing anthracycline cardiotoxicity and sarcopenia in cancer patients.

Anti-Arrhythmic Effects of Heart Failure Guideline-Directed Medical Therapy and Their Role in the Prevention of Sudden Cardiac Death: From Beta-Blockers to Sodium-Glucose Cotransporter 2 Inhibitors and Beyond

Sudden cardiac death (SCD) accounts for a substantial proportion of mortality in heart failure with reduced ejection fraction (HFrEF), frequently triggered by ventricular arrhythmias (VA). This review aims to analyze the pathophysiological mechanisms underlying VA and SCD in HFrEF and evaluate the effectiveness of guideline-directed medical therapy (GDMT) in reducing SCD. Beta-blockers, angiotensin receptor-neprilysin inhibitors, and mineralocorticoid receptor antagonists have shown significant efficacy in reducing SCD risk. While angiotensin-converting enzyme inhibitors and angiotensin receptor blockers exert beneficial impacts on the renin-angiotensin-aldosterone system, their direct role in SCD prevention remains less clear. Emerging treatments like sodium-glucose cotransporter 2 inhibitors show promise but necessitate further research for conclusive evidence. The favorable outcomes of those molecules on VA are notably attributable to sympathetic nervous system modulation, structural remodeling attenuation, and ion channel stabilization. A multidimensional pharmacological approach targeting those pathophysiological mechanisms offers a complete and synergy approach to reducing SCD risk, thereby highlighting the importance of optimizing GDMT for HFrEF. The current landscape of HFrEF pharmacotherapy is evolving, with ongoing research needed to clarify the full extent of the anti-arrhythmic benefits offered by both existing and new treatments.

Decoding signaling mechanisms: unraveling the targets of guanylate cyclase agonists in cardiovascular and digestive diseases

Soluble guanylate cyclase agonists and guanylate cyclase C agonists are two popular drugs for diseases of the cardiovascular system and digestive systems. The common denominator in these conditions is the potential therapeutic target of guanylate cyclase. Thanks to in-depth explorations of their underlying signaling mechanisms, the targets of these drugs are becoming clearer. This review explains the recent research progress regarding potential drugs in this class by introducing representative drugs and current findings on them.

Vericiguat alleviates ventricular remodeling and arrhythmias in mouse models of myocardial infarction via CaMKII signaling

AIMS

Maladaptive ventricular remodeling is a major cause of ventricular arrhythmias following myocardial infarction (MI) and adversely impacts the quality of life of affected patients. Vericiguat is a new soluble guanylate cyclase (sGC) activator with cardioprotective properties. However, its effects on MI-induced ventricular remodeling and arrhythmias are not fully comprehended; hence, our research evaluated the effect of vericiguat on mice post-MI.

MATERIALS AND METHODS

Mice were divided into four treatment groups: Sham, Sham+Veri, MI, and MI + Veri. For the MI groups and MI + Veri groups, the left anterior descending (LAD) coronary artery was occluded to induce MI. Conversely, the Sham group underwent mock surgery. Vericiguat was administered orally daily for 28 days to the Sham+Veri and MI + Veri groups. Additionally, H9c2 cells were cultured for further mechanistic studies. Assessment methods included echocardiography, pathological analysis, electrophysiological analysis, and Western blotting.

KEY FINDINGS

Vericiguat reduced cardiac dysfunction and infarct size after MI. It also mitigated MI-induced left ventricular fibrosis and cardiomyocyte apoptosis. Vericiguat normalized the expression of ion channel proteins (Kv4.3, Kv4.2, Kv2.1, Kv1.5, Kv7.1, KCNH2, Cav1.2) and the gap junction protein connexin 43, reducing the susceptibility to ventricular arrhythmia. Vericiguat significantly inhibited MI-induced calcium/calmodulin-dependent protein kinase II (CaMKII) pathway activation in mice.

SIGNIFICANCE

Vericiguat alleviated MI-induced left ventricular adverse remodeling and arrhythmias through modulation of the CamkII signaling pathway.

The Evolving Role of Vericiguat in Patients With Chronic Heart Failure

Heart failure (HF) is a chronic and progressive clinical disorder characterized by an inability to pump sufficient blood to meet metabolic demands. It poses a substantial global healthcare burden, leading to high morbidity, mortality, and economic impact. Current treatments for HF include lifestyle modifications, guideline-directed medical therapies (GDMT), and device interventions, but the need for novel therapeutic approaches remains significant. The introduction of vericiguat, a soluble guanylate cyclase stimulator, has shown promise in improving outcomes for heart failure patients. Vericiguat addresses the underlying pathophysiological mechanisms of heart failure by augmenting the cyclic guanosine monophosphate (cGMP) pathway, leading to enhanced cardiac contractility and vasodilation. Clinical trials evaluating the efficacy and safety of vericiguat, such as the Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction (VICTORIA) trial, have demonstrated promising results. It has been shown that vericiguat, when added to standard therapy, reduces the risk of HF hospitalization and cardiovascular death in patients with symptomatic chronic HF with reduced ejection fraction (HFrEF). The addition of vericiguat to the current armamentarium of HF treatments provides clinicians with a novel therapeutic option to further optimize patient outcomes. Its potential benefits extend beyond symptom management, aiming to reduce hospitalizations and mortality rates associated with HF. As with any new treatment, the appropriate patient selection, monitoring, and management of potential adverse effects are essential. Further research is warranted to determine the long-term benefits, optimal dosing strategies, and potential combination therapies involving vericiguat. Its ability to target the cGMP pathway provides a unique mechanism of action, offering potential benefits in improving clinical outcomes for HF patients. Continued investigation and clinical experience will further elucidate the role of vericiguat in the management of HF and its overall impact on reducing the healthcare burden associated with this debilitating condition.

Vericiguat preserved cardiac function and mitochondrial quality in a rat model of mitral regurgitation

AIMS

New drugs for heart failure (HF) that target restoring the impaired NO-sGC-cGMP pathway are being developed. We aimed to investigate the effects of vericiguat, an sGC stimulator, on cardiac function, blood pressure (BP), cardiac mitochondrial quality, and cardiac fibrosis in rat models of chronic mitral regurgitation (MR).

MATERIALS AND METHODS

We surgically induced MR in 20 Sprague-Dawley rats and performed sham procedures on 10 rats (negative control). Four weeks post-surgery, we randomly divided the MR rats into two groups: MR group and MR + vericiguat group. Vericiguat (0.5 mg/kg, PO) was administered once a day via oral gavage for 8 weeks, while the sham and MR groups received equivalent volumes of drinking water instead. We took echocardiography and BP measurements at baseline (4 weeks post-surgery) and at the end of study (8 weeks after treatment). At the study end, all rats were euthanized and their hearts were immediately collected, weighed, and used for histopathology and mitochondrial quality assessments.

KEY FINDINGS

Vericiguat preserved cardiac functions and structural remodeling in the MR rats, with significantly lower systolic BPs than baseline values (P < 0.05). Additionally, vericiguat significantly improved the mitochondrial quality by attenuating ROS production, depolarization and swelling when comparing the values in both groups (P < 0.05). The fibrosis area also significantly decreased in the MR + vericiguat group (P < 0.05).

SIGNIFICANCE

Vericiguat demonstrated cardioprotective effects on cardiac function, BP, and fibrosis by preserving mitochondrial quality in rats with HF due to MR.

Practical Patient Care Considerations With Use of Vericiguat After Worsening Heart Failure Events

Vericiguat is a soluble guanylate cyclase stimulator approved by multiple global regulatory bodies and recommended in recently updated clinical practice guidelines to reduce morbidity and mortality in patients with worsening chronic heart failure (HF) with reduced ejection fraction (HFrEF). Despite the growing armaments of evidence-based medical therapy for HFrEF that have demonstrated clinical outcome benefits, there is a need to address residual risk following worsening HF events. When considering therapies aimed to mitigate postevent cardiovascular risk, potential barriers preventing the prescription of vericiguat in eligible patients may include providers' lack of familiarity with it, clinical inertia, limited knowledge about monitoring response to therapy, and concerns about potential adverse effects as well as integration of its routine use during an era of in-person and telehealth hybrid ambulatory care. This review provides an overview of vericiguat therapy and proposes an evidence-based and practical guidance strategy toward implementing its use in various clinical settings. This review additionally summarizes patient counseling points for its initiation and maintenance.

Vericiguat: A Novel Soluble Guanylate Cyclase Stimulator for Use in Patients With Heart Failure

Heart failure (HF) affects 6.2 million Americans and is increasing annually in its frequency. Treatment of HF has been at the forefront of medical advancements due to the financial burden on our health care system. As such, changes to the guidelines regarding standard of care have been evolving over the last decade with the recent additions of sacubitril-valsartan and sodium glucose co-transporter-2 inhibitors to standard of care in the treatment of HF. Despite the aforementioned expansions in treatment options, HF continues to have a significant impact on the American health care system. Most recently, a novel drug vericiguat that targets an unprecedented pathway for the treatment of HF was Food and Drug Administration approved for the management of patients with HF with a reduced ejection fraction with a recent hospitalization or need for outpatient intravenous diuretics. In clinical trials, vericiguat was associated with a reduction in death from cardiovascular causes and first hospitalization in comparison to placebo. The aim of this review is to provide a comprehensive literature analysis of the various trials surrounding the approval of vericiguat and to both inform and synthesize the data surrounding the clinical use of vericiguat. The introduction of Vericiguat should be considered as a treatment option in patients to decrease the mortality/morbidity of HF with reduced ejection fraction and to increase the quality of life.

Sudden cardiac death prevention in the era of novel heart failure medications

Sudden cardiac death (SCD) occurs unexpectedly and is usually a result of ventricular arrhythmia in patients with structural heart disease. The implantable cardioverter-defibrillator (ICD), with or without biventricular pacing, has been proven to be protective for heart failure patients with reduced ejection fraction of <35 % (HFrEF). This device therapy prevents SCD, with additional optimal medications, namely angiotensin-converting enzyme-inhibitors, angiotensin-II receptor-blockers, beta-blockers and mineralocorticoid receptor-antagonists. HFrEF patients present the majority of SCD incidents, as they are characterized by cardiac fibrosis, the main arrhythmogenic element. The introduction of angiotensin-receptor-neprilysin inhibitors, sodium-glucose co-transporter-2 inhibitors and guanylate-cyclase stimulators was associated with reduction of SCD. Additionally, clinical trials have evaluated the improved outcome of these new medications on left ventricular ejection fraction, arrhythmias and HFrEF. These beneficial effects could possibly lead to important changes in decision-making on ICD implantation for primary prevention in patients with HFrEF and reduce the need for device therapy. In this review, we highlight the pathophysiological mechanisms of the new drug agents, and evaluate the possible effect they could have on the role of device therapy as a primary prevention of SCD.

Vericiguat: A Review in Chronic Heart Failure with Reduced Ejection Fraction

Vericiguat (Verquvo^®) is the first oral soluble guanylate cyclase (sGC) stimulator to be approved for the treatment of adults with symptomatic, chronic heart failure with reduced ejection fraction (HFrEF). In the phase III VICTORIA trial, vericiguat added to standard of care (SOC) was associated with a significantly lower risk of the primary composite endpoint of death from cardiovascular (CV) causes or first hospitalization from heart failure (HHF) than placebo added to SOC in adults with chronic HFrEF. The risk of all-cause mortality or first HHF (secondary composite endpoint) and the total number of HHF were also statistically significantly reduced by vericiguat therapy. Vericiguat showed no benefit with respect to the primary endpoint in a subgroup of patients with grossly elevated N-terminal pro-brain natriuretic peptide levels. Vericiguat was generally well tolerated; the most common treatment-related adverse event (AE) was hypotension. AEs of special interest included symptomatic hypotension and syncope, which occurred with low incidences that were similar between treatment groups. Thus, vericiguat is an effective and generally well-tolerated treatment option in patients with symptomatic, chronic HFrEF who have experienced a recent worsening event, expanding the options currently available for chronic HFrEF management.

Contemporary Pillars of Heart Failure with Reduced Ejection Fraction Medical Therapy

Heart failure with reduced ejection fraction (HFrEF) is a clinical condition associated with cardiac contractility impairment. HFrEF is a significant public health issue with a high morbidity and mortality burden. Pathological left ventricular (LV) remodeling and progressive dilatation are hallmarks of HFrEF pathogenesis, ultimately leading to adverse clinical outcomes. Therefore, cardiac remodeling attenuation has become a treatment goal and a standard of care over the last three decades. Guideline-directed medical therapy mainly targeting the sympathetic nervous system and the renin–angiotensin–aldosterone system (RAAS) has led to improved survival and a reduction in HF hospitalization in this population. More recently, novel pharmacological therapies targeting other pathways implicated in the pathophysiology of HFrEF have emerged at an exciting rate, with landmark clinical trials demonstrating additive clinical benefits in patients with HFrEF. Among these novel therapies, angiotensin receptor–neprilysin inhibitors (ARNI), sodium–glucose cotransporter-2 inhibitors (SGLT2i), vericiguat (a novel oral guanylate cyclase stimulator), and omecamtiv mecarbil (a selective cardiac myosin activator) have shown improved clinical benefit when added to the traditional standard-of-care medical therapy in HFrEF. These new comprehensive data have led to a remarkable change in the medical therapy paradigm in the setting of HFrEF. This article will review the pivotal studies involving these novel agents and present a suggestive paradigm of pharmacological therapy representing the 2021 European Society of Cardiology (ESC) guidelines for the treatment of chronic HFrEF.
