About this trial
This is a nationwide, multicenter, registry-based prospective cohort study to assess real-world effectiveness of treatment with a pembrolizumab containing regimen in persistent, recurrent, or metastatic cervical cancer. Patients in the observation cohort continue treatment according to standard of care. In the discontinuation cohort, patients discontinue their maintenance treatment with pembrolizumab (with or without discontinuation of bevacizumab). Patients may choose to discontinue pembrolizumab prematurely (with or without discontinuation of bevacizumab) if they achieve a confirmed CR or a confirmed PR to treatment, or on patient's request or due to toxicity. If an eligible patient chooses not to discontinue treatment early they will remain in the observation cohort. The duration of the trial for the individual patient will be until two years from the start of treatment. Survival follow-up will continue for a maximum of 10 years
Eligibility criteria
Qualifiers
Previous inclusion in the observation cohort
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
Immune-related toxicity grade ≥ 3 OR
Patient's preference (e.g. chronic or invalidating grade 1-2 immune-related toxicity) OR
Disqualifiers
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.
