Study summary

Critically ill Patients are at high risk to develop deep venous thrombosis. However, despite receiving of a standard dose of Low-molecular-weight Heparin(LMWH), many patients still develop life-threatening embolism. The purpose of this study is to evaluate the anti-Xa levels of different dosing regimens of LMWH in critically ill patients in China.

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

Started Aug 2017 (actual). Primary completion is estimated for Mar 2018, 7 months after the start.

Of 439 non-industry observational studies under Critical Illness, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 45. This study's planned 7 months is below that.

Counting every sponsor, half of 442 studies reached it within 23 months; a quarter within 12 and three quarters within 46.

Critical Illness covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

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 17, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
