NCT ID NCT06205628

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
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 This study

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 Results may not be published yet.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

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.

Summary

This early-stage study tests a new drug called ADX-850 in 28 people with mild to moderate high blood pressure. The drug uses siRNA technology to target genes involved in blood pressure regulation. The main goal is to check safety and how the drug moves through the body, with a secondary look at its effect on blood pressure.

What this could mean

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

Active substance
ADX-850 (siRNA drug)
What this could lead to
If successful, this could lead to a new treatment option for high blood pressure that may require less frequent dosing.
What could go wrong
This is an early Phase 1 study with only 28 participants, so safety and effectiveness are not yet proven. The drug may not lower blood pressure enough or could cause unexpected side effects.
