A Clinical Study on the Efficacy and Mechanism of Tumor Treatment Vaccine (TTV) for Recurrent and Refractory Advanced Solid Tumors
Study Details
Study Description
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.

N/A |
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).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tumor treatment vaccine for patients with advanced solid tumors Tumor treatment vaccine(TTV) would be given deep subcutaneously in the arm or near the tumor.The check indexes are image examination (CT, MRI or PET scan) and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell). |
Biological: tumor 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.

Outcome Measures
Primary Outcome Measures
- Relief degree of tumors [The last injection]
It will be evaluated by the Response Evaluation Criteria in Solid Tumors（RECIST1.1）
Secondary Outcome Measures
- Progress free survival（PFS） [1 year]
The duration from the beginning of treatment to cancer recurrence or progression
- Overall survival（OS） [3 years]
The duration from the beginning of treatment to patient death
