Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Apr 2014, a primary completion of Sep 2014 and a completion of Sep 2014. It does not say whether these dates are actual or estimated.

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 Apr 13, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
