Long-term Follow-up of Checkpoint Inhibitors-induced Ileo-colitis

Study Purpose

This is a multicentric, observational study, including all European centres willing to take part. The multicentre nature is necessary for enhancing the generalisability of our results, and due to the rarity of this condition. The study is observational including both retrospective and newly diagnosed cases of CIC with an endoscopically/histologically-proven diagnosis. Detailed characteristics will be collected, with the aim of classifying the disorders from a clinical, endoscopic, and pathological point of view. Age, sex, localisation, and histology of tumour, stage of tumour, oncological response to immune checkpoint inhibitors-induced colitis, colonoscopy, histology, inflammatory parameters, and clinical manifestations will be assessed for each patient, as well as therapy and outcome. The study will consist of 2 part: the first one will be retrospective, while the second one will be prospective al will include all incident patients diagnosed with CIC during the enrolment period.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06899789
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

: Newly diagnosed of CIC patients, with a proven endoscopic and histological diagnosis

The study will include all patients developing colitis (diagnosed with endoscopy and/or histological examination) after at least one administration of a checkpoint inhibitor therapy for advanced cancer. Patients with a previous diagnosis of IBD (before cancer onset or before immunotherapy beginning) will be excluded, as well as patients with a previous diagnosis of other forms of colitis (other than IBD).
