Positive baxdrostat Phase III trial in uncontrolled hypertension

14 July 2025

UK pharma major AstraZeneca (LSE: AZN) today announced positive high-level results from the baxdrostat BaxHTN Phase III trial in patients with uncontrolled or treatment resistant hypertension.

These data showed baxdrostat at two doses (2mg and 1mg) demonstrated a statistically-significant and clinically-meaningful reduction in mean seated systolic blood pressure (SBP) compared with placebo at 12 weeks, marking a potential turning point in how we approach one of the most persistent global health challenges. The trial also successfully met all secondary endpoints. Patients with uncontrolled or treatment resistant hypertension received baxdrostat or placebo on top of standard of care.

AstraZeneca, whose shares edged up almost 2% to 10,762 pence on the news, acquired rights to baxdrostat along with its $1.8 billion buy of USA-based clinical stage biotech CinCor Pharma in 2023.
