What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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

Summary

This early-stage study tests whether it is safe to take nitroglycerin spray (used for chest pain) together with an experimental drug called nurandociguat (designed to help kidneys) in 36 adults with stable coronary artery disease. Both drugs widen blood vessels, so the main concern is a sudden drop in blood pressure. The study will monitor side effects and how the drugs interact in the body.

What this could mean

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

Active substance
Nitroglycerin spray and nurandociguat
What this could lead to
If successful, this could show that combining nitroglycerin with nurandociguat is safe, potentially leading to better treatment options for people with both heart and kidney disease.
What could go wrong
This is a very early Phase 1 safety study with only 36 participants. It is not designed to prove effectiveness, and the combination may cause low blood pressure or other side effects.
