Quick Navigation

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

This is a single-arm, phase II study that will enroll a total of 45 subjects. All subjects will have a confirmed diagnosis of metastatic or unresectable soft tissue sarcoma or bone sarcoma. All subjects must have intact Rb, identified at the time of screening, by immunohistochemistry testing of submitted tumor specimen. Subjects will receive Abemaciclib 200 mg twice daily until progression or discontinuation criteria are met.
