What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a medication called vericiguat to determine if it improves blood vessel function and reduces signs of kidney and brain injury in people undergoing heart surgery. The study compares vericiguat to a placebo (a harmless, inactive pill) to assess which is more effective. It examines whether vericiguat reduces kidney and brain function problems after surgery. Suitable participants for this trial are those planning elective open-heart surgery. As a Phase 4 trial, vericiguat is already FDA-approved and proven effective, and this research aims to understand how it benefits more patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are using other soluble guanylyl cyclase stimulators or phosphodiesterase-5 inhibitors.

What is the safety track record for these treatments?

Research has shown that vericiguat, a type of medication, is generally well-tolerated. In past studies, participants taking vericiguat experienced similar rates of serious events as those taking a placebo, which contains no active medicine. For instance, one study found that the percentage of patients who died from heart failure was similar between the vericiguat group (6.5%) and the placebo group (7.6%). Another study reported that the rate of heart-related death or hospitalization for heart failure was slightly lower in the vericiguat group (35.5%) compared to the placebo group (38.5%).

These findings suggest that vericiguat does not increase the risk of serious side effects compared to not receiving the treatment. Additionally, vericiguat has already received FDA approval for use in some heart failure patients, further supporting its safety. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Unlike traditional heart surgery treatments that primarily focus on managing symptoms or existing damage, Vericiguat is unique because it works by enhancing the soluble guanylate cyclase (sGC) pathway. This is a new mechanism that helps improve blood flow and reduce organ injury during heart surgery. Researchers are excited about Vericiguat because it could potentially lead to better recovery outcomes by protecting organs from damage during the procedure, something current treatments don't directly address.

What evidence suggests that vericiguat might be an effective treatment for vascular function and organ injury in heart surgery patients?

This trial will compare Vericiguat with a placebo to evaluate its effects on vascular function and organ injury in heart surgery patients. Research has shown that Vericiguat can help reduce risks associated with heart failure. Studies have found that it lowers the chances of dying from heart-related issues and needing hospitalization for heart failure. In trials, participants taking Vericiguat experienced a 10% drop in major heart failure events. Evidence also indicates that it improves blood vessel function, suggesting Vericiguat could protect the heart, kidneys, and brain during heart surgery. ^{1 3 4 6 7}

Published Research Related to This Trial

In a study involving nine anesthetized pigs, ventriculocisternal perfusion of bupivacaine led to significant increases in heart rate and blood pressure, indicating an indirect cardiovascular stimulating effect via the central nervous system.

The cardiovascular changes induced by bupivacaine were reversible upon wash-out with mock cerebrospinal fluid, suggesting that the drug's effects on the cardiovascular system may be linked to its action on the CNS rather than direct cardiac toxicity.

Lidocaine and bupivacaine significantly increase capillary blood flow in a dose-dependent manner, with bupivacaine showing the highest increase, indicating a strong vasodilatory effect.

Mepivacaine, on the other hand, does not enhance blood flow beyond saline levels and may even reduce blood flow at lower concentrations, suggesting a mild vasoconstrictor effect.

In the VICTORIA trial involving 5050 patients with chronic heart failure, vericiguat demonstrated a 10% reduction in the risk of cardiovascular death or heart failure hospitalization compared to placebo, indicating its efficacy in managing severe heart failure.

Vericiguat was found to be safe and well-tolerated, with no significant differences in rates of syncope or hypotension, and it did not require laboratory testing, making it a convenient option for patients.

Clinical trials comparing venotropic drugs to placebo are crucial for assessing their effectiveness, focusing on three key areas: increasing venous tone, reducing capillary permeability, and improving microcirculation.

Calf plethysmography is a reliable method for measuring venous tone, while fluorescein angioscopy is the most sensitive for assessing capillary permeability, although not widely available; laser-Doppler is effective for evaluating microcirculation impairment and correlates well with chronic venous insufficiency severity.

In a study involving seven anesthetized rabbits, both levobupivacaine and bupivacaine significantly impaired heart contractility at doses above 1.32 mg/kg, indicating a risk of cardiac depression with these drugs.

Ropivacaine, however, did not show a significant impact on contractility at a clinical dose of 4.25 mg/kg, suggesting it may be a safer alternative in terms of cardiac effects compared to bupivacaine and levobupivacaine.

In the VICTORIA trial, patients with lower left ventricular ejection fraction (LVEF) had higher levels of certain biomarkers and experienced worse clinical outcomes, indicating a more severe heart failure condition.

Vericiguat showed consistent efficacy across different LVEF levels, with the most significant benefit observed in patients with the lowest LVEF (≤24%), suggesting it is a valuable treatment option for patients with varying degrees of heart failure severity.

Vericiguat is a new medication that stimulates soluble guanylate cyclase (sGC) to increase cGMP production, which helps treat chronic heart failure without relying on nitric oxide.

It was recently approved in the USA for patients with heart failure and an ejection fraction of less than 45%, based on positive results from the phase III VICTORIA trial.

Vericiguat was found to be ineffective in reducing cardiovascular deaths or hospitalizations related to heart failure, based on a meta-analysis of four studies involving 6705 patients.

The study showed no significant difference in adverse effects between patients taking vericiguat and those on placebo, suggesting that it may be safe but not effective for heart failure treatment.

Both bupivacaine and levobupivacaine cause a rapid increase in skin blood flow that is dose-dependent, indicating their potential for effective local anesthetic use.

At higher concentrations, bupivacaine shows a sustained vasodilation effect, while at lower doses, both drugs can lead to vasoconstriction, suggesting a complex interaction that may influence their therapeutic applications.

In a study involving 30 healthy juvenile pigs, the sGC stimulator riociguat showed a significant vasodilatory effect in systemic circulation, working in an additive manner with nitric oxide (NO), which could be beneficial in various cardiovascular disease states.

In contrast, the sGC activator cinaciguat completely blocks the endogenous NO effect, making it less favorable for clinical application due to its complex interaction with NO-tone and limited vascular control.
