Overview
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.
Interventions
- Biological Tumor Treatment Vaccine; PD-1/L1 inhibitors
Before and after the patient's treatment period using PD-1 inhibitors，patients will receive tumor treatment vaccine(TTV), which would be given deep subcutaneously in the arm or near the tumor.The initial dose is 1ml each time, if the reaction isn't obvious, the dose can be appropriately increased to 2.5-4.0ml each time.The interval between injections can be shortened or extended depending on the patient's condition and response.
Primary outcome measures
- Relief degree of tumors [Time frame: immediately after the last treatment]
