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 goal of this exploratory study is to evaluate the effect of neflamapimod in participants with nonfluent variant primary progressive aphasia (nfvPPA). We aim to evaluate the safety, pharmacokinetics and clinical effects of neflamapimod of participants with nfvPPA.
