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 Results may not be published yet.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

Summary

This study tests a special pacemaker setting designed to lower blood pressure in people with hypertension. About 500 adults who already have or need a pacemaker will take part. The goal is to see if this new setting safely reduces average blood pressure over 24 hours, compared to standard pacing.

Why investors are watching

Orchestra BioMed is running a 316-patient trial that tests whether a software change in a standard Medtronic pacemaker can lower blood pressure. For a micro-cap company with few other products, this readout could determine whether its main technology works and whether it has a viable business.

If it works: A positive result could validate the company's approach and make its technology attractive to a larger partner or buyer. That could give the company a path to revenue without needing to build its own sales force.

If it fails: Trials fail often, and a negative or delayed result could leave the company without a clear product. Because the company is very small, a setback in this single study could put its future in question.
