NCT06680401

Brief Summary

The EHE observational study was developed to obtain a high number of datas such as clinical presentation, natural history, and treatment outcomes, cto identificate cytokines and hormones as biomarkers and generate patient-derived preclinical models as a tool to assess the activity of anticancer agents and validate novel therapeutic targets
