Can a shot help when blood pressure pills fall short?
NCT ID NCT07835984
First seen Sep 23, 2026 · Last updated Sep 24, 2026 · Updated 1 time
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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥ 18 years, of either sex. * Treated hypertension on stable therapy with up to 1 or 2 antihypertensive medications. Stable therapy is defined as having no change in antihypertensive medication or dose within 4 weeks prior to randomization. * Mean sitting systolic blood pressure (msSBP) ≥ 140 mmHg and \< 180 mmHg at the randomization visit. * Willing to participate in the study and provide written informed consent. Exclusion Criteria: * Secondary hypertension. * orthostatic hypotension. * Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>2.5× upper limit of normal (ULN); Total bilirubin \> 1.5 × ULN; International normalized ratio (INR) \> 2.0; Serum potassium \> 5.0 mmol/L or \< 3.5 mmol/L; eGFR≤30 mL/min/1.73m\^2. * Received an investigational agent within the last 3 months. * Type 1 diabetes mellitus, poorly controlled Type 2 diabetes mellitus. * History of any cardiovascular event within 12 months. * History of intolerance to SC injection(s).
