The control arm entails a clinical and radiological follow-up, with no further treatment (current standard of care). ATOMICC trial is an investigator-driven trial sponsored by GEICO (Grupo Español de Investigación en Cáncer de Ovario) and supported by GlaxoSmithKline (GSK).Major Inclusion/Exclusion Criteria Women aged over 18 years with a biopsy-confirmed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the cervix meeting the following staging criteria: International Federation of Gynecology and Obstetrics (FIGO) 2009 stages IB2, IIA2, IIB with pelvic lymph node involvement, FIGO stages IIIA, IIIB, IVA, and any FIGO 2009 stage with para-aortic lymph node involvement are eligible for the trial. All patients must have achieved a partial or complete response after definitive concurrent chemoradiation. Women diagnosed with FIGO stage IVB, having undergone a previous hysterectomy, or having a history of active autoimmune disease will not be considered eligible.Primary Endpoint Progression-free survival defined as the time from the date of randomization to the date of first disease progression or death due to any cause, whichever occurs first.Sample Size A total of 132 patients are expected to be recruited in the study, using a 1:2 (control:experimental arm) randomization allocation ratio.Estimated Dates for Completing Accrual and Presenting Results The trial was launched in Q2-2019 and the trial is estimated to be closed for recruitment in Q3-2022. Results are expected to be released in Q3-2024.Trial Registration The trial is registered at ClinicalTrials.gov (NCT03833479).No data are available. ER -
