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.

Conditions

Solid Tumors, Adult

Keywords

Tumor immunotherapy; Tumor vaccine; Advanced solid tumor

Outcome Measures

Primary Outcomes (1)

• Relief degree of tumors

  It will be evaluated by the Response Evaluation Criteria in Solid Tumors（RECIST1.1）

  The last injection

Secondary Outcomes (2)

• Progress free survival（PFS）

  1 year

• Overall survival（OS）

  3 years

Study Arms (1)

Tumor treatment vaccine for patients with advanced solid tumors

EXPERIMENTAL

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

Interventions

tumor treatment vaccine injection BIOLOGICAL

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.
