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.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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
Cancelled before anyone took part.

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.

When the status isn't known

Summary

This trial compares two anti-seizure drugs, levetiracetam and valproic acid, in people with glioma who have had a first seizure. The goal is to see which drug better prevents further seizures over six months. Currently, the choice of drug is based on doctor preference, as there is no clear evidence favoring one. The study will also look at why patients might stop treatment and how well each drug is tolerated.

What this could mean

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

Active substance
levetiracetam and valproic acid
What this could lead to
If one drug proves more effective, it could establish a standard first-choice treatment for seizures in glioma patients, improving seizure control and quality of life.
What could go wrong
This is a phase 4 trial with 120 participants, so results may not apply to all glioma patients. Both drugs have side effects, and the trial may not show a clear winner.
