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

Phase 1 study comprised of open-label, dose escalation, multiple cohorts of P-BCMA-ALLO1 allogeneic T stem cell memory (Tscm) CAR-T cells in subjects with relapsed / refractory Multiple Myeloma (RRMM).
