NCT ID NCT04588428

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 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 Results may not be published yet.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
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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This Phase 2 trial tested a new DNA vaccine called INO-4700 in 192 healthy adults to see if it is safe and can trigger an immune response against MERS, a serious coronavirus. The vaccine is given as a shot under the skin followed by a quick electric pulse to help cells take up the DNA. The study looked at side effects and measured antibodies and T-cell responses.

What this could mean

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

Active substance
INO-4700 (DNA vaccine given under the skin followed by a mild electric pulse to boost uptake)
What this could lead to
If successful, this could lead to a vaccine that protects people from MERS, a serious respiratory virus.
What could go wrong
This is a Phase 2 trial with only 192 healthy volunteers, so it is still early. The vaccine may not produce strong enough immunity or could cause side effects like injection site reactions.
