Combining rituximab with prior therapies for advanced liver cancer

A Study on the Efficacy and Safety of Rituximab When Combined With Prior Targeted Therapy and Checkpoint Immunotherapy as Second-line or Later Therapy in Patients With Advanced Hepatocellular Carcinoma

Phase 2 Interventional Tianjin Medical University Cancer Institute and Hospital · NCT06301399

This study is testing if adding rituximab to other treatments can help people with advanced liver cancer who haven't had success with previous therapies.

What this trial studies

This study evaluates the efficacy and safety of adding rituximab to treatment regimens for patients with advanced hepatocellular carcinoma who have previously failed other therapies. Participants will receive rituximab in conjunction with PD-1 or PD-L1 inhibitors and targeted therapy. The study aims to determine if this combination can improve outcomes for patients who have not responded to prior treatments. The trial will include patients aged 17 to 79 with confirmed advanced liver cancer.

Who should consider this trial

Good fit: Ideal candidates are adults aged 17-79 with advanced hepatocellular carcinoma who have experienced progression or intolerance after prior treatments.

Not a fit: Patients who have not been diagnosed with advanced hepatocellular carcinoma or those who have not failed previous therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new treatment option for patients with advanced hepatocellular carcinoma who have limited options after previous therapies.

How similar studies have performed: While there have been studies exploring the use of rituximab in various cancers, this specific combination approach in advanced hepatocellular carcinoma is relatively novel.
