Interventions

  • Combination productSaline delivered using an intrauterine pressure catheter (IUPC)

    An intrauterine pressure catheter (IUPC) will be placed in participants after membrane rupture, or at 4 cm if membranes previously ruptured. A 300cc bolus of normal saline will be administered. A continuous rate of 100 cc/hr of normal saline will continue until delivery to prevent Postpartum Hemorrhage. If the IUPC is dislodged, it will be replaced by a trained clinician.

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

Start is estimated for Nov 2024; primary completion for Nov 2026, 24 months later.

Of 18 phase 3 interventional studies under Postpartum Hemorrhage, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 26. This study's planned 24 months is above that.

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 Nov 18, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
