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 H3 TAR Prosthesis was approved by FDA (P160036) on June 4, 2019. Continued approval of the premarket approval application (PMA) is contingent upon the submission of periodic reports (Annual Report), required under 21 CFR 814.84. In order to provide continued reasonable assurance of the safety and effectiveness of the PMA device, data from this post-approval study must be submitted to FDA in a PMA Post-Approval Study Report per the requirements set forth in the approval.
