Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to assess the efficacy and safety of nipocalimab in reducing the risk of severe fetal and neonatal alloimmune thrombocytopenia (FNAIT).
