RECRUITING

A Study of Tegavivint (BC2059) in Patients With Advanced Hepatocellular Carcinoma

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

This study will be conducted in 2 parts. The first part is a phase 1 single-agent dose escalation, and dose optimization, study of tegavivint in patients with advanced HCC after failure of at least one line of prior systemic therapy. The second part of the study will begin with a brief dose escalation part for each combination (tegavivint plus cabozantinib or tegavivint plus lenvatinib) followed by a combination dose expansion.
