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.
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 Results may not be published yet.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 This study
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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tested a drug called Cytotect, which contains antibodies against the CMV virus, to prevent CMV infection in people who had a stem cell transplant and developed graft-versus-host disease (GVHD). These patients are at high risk for CMV, and current antiviral drugs often cause serious side effects. The trial was very small and was stopped early, so we cannot draw firm conclusions about how well Cytotect works.

What this could mean

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

Active substance
Cytotect (hyperimmune anti-CMV immunoglobulin)
What this could lead to
If it works, this could provide a safer way to prevent CMV infection in high-risk transplant patients, avoiding the severe side effects of current antiviral drugs.
What could go wrong
This was a very small, early-phase trial that was terminated early with only 2 participants, so results are not reliable. The drug may not prevent CMV infection effectively.
