Safety and Efficacy of PD-1 Inhibitors in Patients With Liver Transplant

• Status: Recruiting
• Trial end date: 2022-10-31
• Target enrollment: 0
• Participant gender: All

Summary

This is a perspective clinical study to assess the safety and efficacy of PD-1 inhibitors in patients with LT. Eligible patients have recurrent or metastatic cancer after LT, are not amenable to, or refractory after, locoregional therapy or to a curative treatment approach (eg, surgery, or ablation) and have previously been treated with sorafenib or other targeted therapy, either intolerant to this treatment or show radiographic progression after treatment.

Biopsy is needed to exclude patients with positive allograft PD-L1 expression.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Shanghai Zhongshan Hospital
• Treatments: Immune Checkpoint Inhibitors
