Veri-T: A Trial of Verdiperstat in Patients With svPPA Due to TDP-43 Pathology

Conditions

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

The purpose of the study is to test the safety and tolerability of twice daily Verdiperstat in patients with semantic variant primary progressive aphasia (svPPA) due to frontotemporal lobar degeneration with TDP-43 pathology (FTLD-TDP). Three-fourths of the participants will receive Verdiperstat and one-fourth will receive Placebo during the 24-week treatment duration.
