Clinical Efficacy of Tumour Treatment Vaccine (TTV) Combined With PD-1 in the Treatment of Relapsed Refractory Advanced Solid Tumours

Not Applicable

Recruiting

• Conditions: Cancer; PD-L1 Gene Mutation
• Interventions: Biological: Tumor Treatment Vaccine; PD-1/L1 inhibitors

• Registration Number: NCT06430502
• Lead Sponsor: Wuxi People's Hospital

Brief Summary

This study is intended to investigate the clinical efficacy of TTV vaccine combined with PD-1/PD-L1 inhibitor in the treatment of relapsed and refractory advanced solid tumours from a clinical perspective.

Detailed Description

The innovative invention of Tumour Treatment Vaccine (TTV) has been verified in previous studies that the TTV vaccine can play a good role in enhancing the anti-tumour effect of immune checkpoint inhibitor therapy, and the tumour suppression rate of combined anti-PD-1 inhibitor reaches 75.96%. Therefore, this study is intended to investigate the clinical efficacy of TTV vaccine combined with PD-1/PD-L1 inhibitor in the treatment of relapsed and refractory advanced solid tumours from a clinical perspective.
