Recruitment status, easiest to join first

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.

Summary

Researchers are testing GW906, an experimental subcutaneous injection, as an add-on treatment for adults whose high blood pressure is not controlled by one or two standard medications. The trial enrolls about 560 people with systolic blood pressure between 140 and 180 mmHg despite stable treatment. Participants receive either GW906 or a placebo injection for 24 weeks, and researchers measure changes in seated blood pressure at 12 weeks and other time points.

What this could mean

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

Active substance
GW906 (SAL0132), an experimental injectable drug for high blood pressure
What this could lead to
If it works, GW906 could offer an extra option for people whose blood pressure stays high despite taking one or two medications.
What could go wrong
This is a phase 2 trial, so researchers do not yet know if GW906 lowers blood pressure or what side effects it may cause. Results may not apply to everyone with hypertension.
