Cabozantinib Treatment in a Phase II Study for Patients With Hepatocellular Carcinoma (HCC) Refractory to PD-1 Inhibitors

• Status: Recruiting
• Trial end date: 2023-12-07
• Target enrollment: 0
• Participant gender: All

Summary

The CaPture trial is a prospective, multi-centre, non-randomized phase II study. Its aim is to assess feasibility, safety and efficacy signals of Cabozantinib treatment in patients with HCC and prior non-response or disease progression during a PD-1 or PD-L1 inhibitor treatment. Since the potential study population is very small, the sample size has been fixed in advance to N = 40. Time on treatment (TT) will be measured as primary endpoint.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: University of Leipzig
