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 main aim of this study is to learn how safe elritercept is and how well adults with anemia associated with lower-risk MDS tolerate treatment with different doses of elritercept. Other aims are to learn how safe elritercept is by looking at how many participants have MDS that worsens during the study and learn about the effects of elritercept on anemia linked to MDS. The study will also look to learn how elritercept affects the production of healthy RBCs.
