Summary

Multi-cohort exploratory prospective study. Participation in the ALCINA 4 study does not change the standard management of the patient, including the treatments administered. A sampling schedule will be set up for each cohort. Depending on the clinical context studied and the biomarkers studied and/or sought, the timing of blood samples will vary between cohorts.
