NCT ID NCT05051722

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 study aims to develop a screening test that uses a vaginal swab and blood sample to find DNA markers for endometrial, ovarian, and cervical cancers. Researchers at Mayo Clinic will enroll over 3,000 women to see if the test can accurately detect these cancers at an early stage. The goal is to create a simple, non-invasive tool that could catch gynecologic cancers sooner.

What this could mean

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

Active substance
Methylated DNA markers and high-risk human papilloma virus (HR-HPV) detection in vaginal fluid and blood
What this could lead to
If successful, this could lead to a simple, non-invasive screening test that detects multiple gynecologic cancers early, potentially improving survival rates.
What could go wrong
This is a Phase II biomarker study, not a treatment trial. The test may not prove accurate enough in larger, diverse populations, and false positives or negatives are possible.
