Authors' conclusion

In a population with mild-to-moderate BP elevation, both dose versions of the novel low-dose triple single-pill combination showed good tolerability and clinically relevant BP reductions compared with placebo.

Study context

Population
Adults with hypertension receiving 0 to 1 blood pressure (BP)-lowering drugs, home systolic BP (SBP) 130 to 154 mm Hg after 2-week placebo run-in96% completed
Participants
295 adults
Comparison
Low-dose triple single-pill combination vs placebo
Primary endpoint
Difference in change in home SBP from randomization (primary safety: treatment discontinuation due to an adverse event)
Follow-up
Week 4

Primary result

As reported in the abstract

Home SBP, placebo-corrected least square mean difference

Least square mean difference, mm Hg

GMRx2 ¼ dose
−7.3 (95% CI −4.5 to −10.2)
GMRx2 ½ dose
−8.2 (95% CI −5.2 to −11.3)
