NCT ID NCT07733557

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 Results may not be published yet.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

Summary

This study is testing whether human papillomavirus (HPV) can be accurately detected from menstrual blood collected at home. Participants who had a routine HPV test within the past 90 days will use a special kit to collect a menstrual blood sample. The results will be compared with their earlier clinical test to see if the two methods agree. If successful, menstrual blood sampling could become a noninvasive, convenient option for HPV screening.

What this could mean

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

Active substance
Endometrics Menstrual Blood Collection Kit (a self-collection device for menstrual blood sampling)
What this could lead to
If menstrual blood testing proves accurate, it could offer a simpler, less invasive way to screen for HPV without a clinic visit.
What could go wrong
This is a small, early-stage study with only 50 participants. The menstrual blood test may not match the accuracy of standard cervical HPV testing.

Exclusion Criteria: * Had an HPV test in the past 90 days, but the result was unclear, invalid, or could not be interpreted. * Are currently pregnant. * Have had a hysterectomy that removed the cervix. * Are not currently having menstrual periods or are unable to provide a menstrual blood sample during the study period. * Have a medical, mental health, cognitive, social, or other condition that, in the opinion of the study doctor, could make it difficult to safely participate or complete the study procedures. * Are unable to understand the study requirements, use the collection kit, or return the sample for testing. * Do not wish to participate, withdraw consent, or are unwilling to complete the required study procedures. * Are taking part in another research study or have another circumstance that, in the opinion of the study team, could affect study results or participant safety. * Are currently incarcerated.
