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

Primary objective: Safety and tolerability of NKX019, administered after lymphodepletion (LD). Secondary objectives: * Assess clinical activity of NKX019 in subjects with systemic lupus erythematosus (SLE) with or without active lupus nephritis (LN) * Characterize pharmacokinetics (PK) of NKX019 * Characterize immunogenicity of NKX019
