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.

Currently receiving treatment in another investigational device or drug study, or less than 28 days since ending treatment on another investigational device or drug study. 14. Expected to require other cancer therapy while on study with the exception of local radiation treatment to the site of bone and other metastasis for palliative pain management. Concurrent endocrine therapy or trastuzumab therapy is allowed if clinically indicated. Concurrent bone modifying agents (including denosumab or zoledronic acid) is allowed for patients with bone metastases. 15. Female subject is pregnant or breast-feeding, or planning to become pregnant during study treatment or 4 months after the last dose of pembrolizumab 16.
