Timeline

Tracking since Sep 25, 2026

Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Nov 2013, a primary completion of Nov 2016 and a completion of Nov 2016. 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.
