Is this trial a fit for you?

Likely a good fit

Adults with persistent, recurrent, or metastatic cervical cancer starting or already on a pembrolizumab-containing regimen.

Probably not a fit

Patients who do not respond or tolerate pembrolizumab may see limited or no benefit from stopping early.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This nationwide, multicenter registry prospectively tracks outcomes for patients receiving pembrolizumab-based therapy in real-world settings. It includes an observation cohort continuing treatment per standard of care and an early-discontinuation cohort for patients stopping pembrolizumab (with or without bevacizumab) for reasons such as sustained response, toxicity, or personal choice. Follow-up extends up to two years per patient, with survival data collected for up to 10 years. The study aims to understand real-world effectiveness, safety, and treatment patterns beyond controlled trials.

Why it matters

Potential benefit: Patients could gain clearer insights into when stopping pembrolizumab might be safe while maintaining benefit.

How similar studies have gone: Other pembrolizumab-based cervical cancer studies have informed practice, but real-world registry data on early discontinuation strategies are relatively novel.

Show full inclusion / exclusion criteria
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.
