Brief summary

This is a study of the clinical efficacy and mechanism study of tumor treatment vaccine (TTV, also known as Neo-BCV) in patients with recurrent and refractory advanced solid tumors.

Detailed description

The study aims to explore the safety and effectiveness of Neo-BCV in the treatment of advanced solid tumors.The safety will be evaluated by statistics of adverse reactions. The efficacy will be evaluated according to local relief degree, progress free survival (PFS) and overall survival (OS).

Interventions

BIOLOGICALtumor treatment vaccine injection

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 / week, if the reaction isn't obvious, the dose can be appropriately increased to 2.5-4.0ml / week.The interval between injections can be shortened or extended depending on the patient's condition and response.The duration of treatment should be extended as long as possible, at least 6-12 months.
