What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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.

Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This phase 3 trial investigates whether N-acetyl cysteine (NAC), an antioxidant supplement, can improve recovery in people hospitalized with an acute ischemic stroke. Participants receive either NAC or a placebo (saline) shortly after admission, and researchers track their neurological function and markers of inflammation. The goal is to see if NAC can reduce stroke-related disability and dampen the body's harmful inflammatory response.

What this could mean

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

Active substance
N-acetyl cysteine (NAC) given as a 600 mg oral solution every 8 hours for 3 days after hospital admission
What this could lead to
If NAC proves effective, it could offer a simple, widely available treatment to improve recovery and reduce disability after an acute ischemic stroke.
What could go wrong
This is a single-center trial with a modest number of participants, and results may not generalize. NAC's benefits beyond standard care remain uncertain, and it is not a replacement for clot-busting drugs when those are appropriate.
