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 Results may not be published yet.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

Summary

This study follows 261 people with persistent, recurrent, or metastatic cervical cancer who are taking pembrolizumab (Keytruda) with or without bevacizumab (Avastin). Some participants may choose to stop pembrolizumab early if their tumor shrinks or disappears, while others continue standard treatment. Researchers will track how long the cancer stays under control and compare results to previous trials, aiming to see if early discontinuation is a safe option.

What this could mean

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

Active substance
pembrolizumab (Keytruda) with or without bevacizumab (Avastin)
What this could lead to
If successful, this could show that stopping pembrolizumab early is safe and effective for some patients with advanced cervical cancer, potentially reducing treatment burden.
What could go wrong
This is an observational registry, not a controlled trial, so results may be less definitive. Early discontinuation might lead to higher relapse risk, and findings may not apply to all patients.

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

Inclusion criteria for the observation cohort: \- Persistent, recurrent, or metastatic cervical cancer commencing treatment or currently treated with a pembrolizumab containing regimen. Inclusion criteria for the early discontinuation cohort: * Previous inclusion in the observation cohort * Choice made to stop pembrolizumab for one of the following reasons: 1. Confirmed complete response if they had received at least 8 cycles of 3- weekly pembrolizumab, including at least 9 weeks beyond a CR (consistent with KEYNOTE-826 criteria) OR 2. Immune-related toxicity grade ≥ 3 OR 3. Patient's preference (e.g. chronic or invalidating grade 1-2 immune-related toxicity) OR 4. Confirmed partial response if they had received at least 8 cycles of 3- weekly pembrolizumab, including at least 9 weeks beyond a PR (timing consistent with KEYNOTE-826 criteria) * Eligible and willing to discontinue pembrolizumab (with or without discontinuing bevacizumab) Exclusion criteria for all cohorts are: * Malignant other disease other than cervical carcinoma that required active treatment in the past 2 years: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, transitional cell carcinoma of urothelial cancer, or any carcinoma in situ that have undergone potentially curative therapy are not excluded * Any psychological, familial, sociological or geographical condition or a known psychiatric or substance abuse disorder potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial. This comprises each and every condition or circumstance preventing the patient from showing up to the outpatient controls and/or undergoing the CT-scans, or preventing the patient from (adequately) filling out the questionnaires.
