What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how the immune system and blood clotting change in the first day after a stroke treated with a clot-removal procedure called thrombectomy. Researchers will collect blood samples from 1,200 participants to find markers that might predict how well people recover at 3 and 12 months. The goal is to better understand the body's response and improve future stroke care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors predict which stroke patients will recover better, leading to more personalized care after thrombectomy.
What could go wrong
This is an observational study, not testing a new treatment. It may not find clear links between immune markers and recovery, and results may not change current care.
