What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether vericiguat, a drug that relaxes blood vessels, can protect the body during heart surgery. About 170 adults scheduled for open-heart surgery will receive either vericiguat or a placebo starting two days before the operation. Researchers will measure blood vessel function and markers of kidney and brain injury to see if vericiguat reduces damage. The goal is to understand why some patients experience kidney or brain problems after heart surgery and whether this drug can help.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
vericiguat (a soluble guanylyl cyclase stimulator)
What this could lead to
If it works, vericiguat could become a standard pre-surgery treatment to reduce kidney and brain injury in heart surgery patients.
What could go wrong
This is a mechanistic trial, not a proof of cure. Results may not translate to better outcomes, and vericiguat can cause low blood pressure or other side effects.
