NCT ID NCT07562984

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 Results may not be published yet.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

Summary

This study is testing a comprehensive program to help adolescent girls aged 9-17 and their parents make informed decisions about the HPV vaccine. The program includes educational materials, shared decision-making conversations, and reminders. Researchers will compare vaccination rates and decision-making quality between those who receive the program and those who get standard care.

What this could mean

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

Active substance
behavioral intervention (education, shared decision-making, reminders)
What this could lead to
If successful, this could provide a practical, evidence-based program to increase HPV vaccination rates among adolescent girls.
What could go wrong
This is an early-stage behavioral study with 300 participants, so results may not apply broadly. The intervention may not significantly change vaccination behavior.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 300 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Apr 2026

An estimate. Start dates often move.

Expected to finish

Nov 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

9 to 17 years

Sex

Female participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Female, aged 9-17 years (inclusive of 9 and 17 years old). 2. Attending pediatric \& adolescent gynecology, adolescent health clinics, or related pediatric/child healthcare clinics at the research centers; or attending vaccination clinics for non-HPV vaccinations (e.g., influenza, tetanus). 3. Has not received any dose of HPV vaccine and has no definitive plan for HPV vaccination on the day of the visit (confirmed by investigator inquiry). 4. Accompanied by at least one primary caregiver (parent or legal guardian) who can comprehend the study content and is willing to participate in shared decision-making interventions. 5. Plans to reside mostly in the region where the research center is located for the next 12 months to facilitate follow-up. 6. Caregiver provides written informed consent; adolescent provides informed consent/assent per local ethical requirements. Exclusion Criteria: 1. Previous completion of or initiation of any HPV vaccine series. 2. History of severe allergic reaction to any HPV vaccine or its main components, or assessed by a vaccinating physician as currently unsuitable for HPV vaccination. 3. Comorbid severe physical illness (e.g., severe cardiopulmonary disease, active malignancy) or severe mental disorder, judged by the investigator as unsuitable for participation or likely unable to complete follow-up. 4. Participation in other clinical studies highly related to HPV vaccination behavior intervention within the past year, which may interfere with the evaluation of this study's intervention effect. 5. Currently receiving treatment for HPV-related diseases (e.g., genital warts) where the physician considers vaccination currently inadvisable. 6. History of autoimmune diseases or tumors. 7. Other situations deemed by the investigator to affect study adherence or interpretation of results (e.g., families with extremely high mobility).
