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 This study
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 Results may not be published yet.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

Details not published

Summary

This trial tests whether the 9-valent HPV vaccine is safe and triggers a protective immune response in adults with HIV. People with HIV face higher risks of HPV infection and related cancers, but vaccine research in this group is limited. The study enrolls 60 HIV-infected adults and 20 healthy controls, giving three doses over six months and following participants for two years. Researchers will measure antibody levels, immune cell responses, and side effects to see if the vaccine works as well in HIV-infected individuals as in healthy people.

What this could mean

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

Active substance
9-valent human papillomavirus (HPV) vaccine
What this could lead to
If the vaccine proves safe and effective in people with HIV, it could help prevent HPV-related cancers in this higher-risk group and guide vaccination guidelines.
What could go wrong
This is an early-stage trial with a small number of participants, so results may not apply to everyone. The vaccine might not produce a strong immune response in people with advanced HIV, and side effects are possible.
