Study summary

This is a double-blind, placebo-controlled, multicenter, efficacy and safety study of firibastat (QGC001) administered po bid over 12 weeks in male and female subjects ≥18 years of age at Screening, with uncontrolled primary HTN. Subjects will be randomized 1:1 to investigational product (IP) and will receive either firibastat (QGC001) or matching placebo on top of their current chronic antihypertensive treatments.

Read the detailed description

The primary objective of this study is to assess the effects of administration of firibastat (QGC001) 500 mg oral (po) twice daily (bis in die [bid]) on blood pressure (BP) over 12 weeks in subjects with uncontrolled primary HTN.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2020 to primary completion in Aug 2022, 26 months.

Of 178 industry-sponsored phase 3 interventional studies under Hypertension, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 38. This study's 26 months is above that.

Counting every sponsor, half of 229 studies reached it within 23 months; a quarter within 13 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 20, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
