Eligibility Criteria
Inclusion Criteria:
- Agree to sign informed consent, willing to follow the study procedures.
- Age 18 ~ 75 years old (including boundary value), male or female.
- ECOG 0-1.
- Histologically or cytologically confirmed advanced bladder cancer,relapsed and metastasized after radiotherapy or immunotherapy.
- Life expectancy >12 weeks.
- Agree to provide last surgical specimens (including paraffin blocks, paraffin embedded sections, etc.).
- At least 6 weeks after previous anti-tumor treatment (radiotherapy, chemotherapy and immunotherapy) and the first administration of this trial.
- Appropriate organ function and hematopoietic function: neutrophil count (neut ≥ 1.5 × 109/L; White blood cell count (WBC) ≥ 3.0 × 109/L; Platelet count ≥ 100 × 109/L; Hemoglobin ≥ 90g / L; Serum creatinine ≤ 1.5 times the upper limit of normal value (ULN); AST and alt ≤ 2.5 times ULN; Serum total bilirubin ≤ 1.5 times ULN; Activated partial thromboplastin time (APTT) ≤ 1.5 times ULN (except for patients undergoing anticoagulant therapy).
- Agree to take effective contraceptive measures during treatment and at least 180 days after the last treatment.
Exclusion Criteria:
- The primary tumor was upper urinary tract and ureteral urothelial carcinoma.
Malignant tumors other than bladder urothelial carcinoma within 5 years before enrollment.
except:
①Prostate cancer with local low risk (stage ≤ T2b, Gleason score ≤ 7, PSA ≤ 20ng / ml, no recurrence after treatment (judged by reviewing PSA level)).
②Low risk prostate cancer (stage T1 / T2a, Gleason score ≤ 7, and PSA ≤ 10NG / ml, in the observed but untreated stage.
③For malignant tumors that meet other inclusion criteria but have a very low risk of metastasis or death, after standard treatment, recheck the patients whose imaging and disease-specific tumor markers show no recurrence or metastasis, such as fully treated cervical cancer in situ, basal or squamous cell skin cancer; Ductal carcinoma in situ after treatment and operation.
- Active autoimmune diseases and need systemic treatment in the past two years (i.e. long-term use of corticosteroids or immunosuppressive drugs). Alternative therapies (such as thyroxine, insulin or physiological corticosteroid replacement therapy for adrenal or pituitary insufficiency) are excluded.
- Expected to have major surgery during the study period or had major surgery within 4 weeks before administration.
- Received other vaccines within 30 days before the first administration (including new crown vaccine)
- Any immune related toxicity caused by previous cancer treatment did not return to ≤ grade 1 (except for grade 2 endocrine system diseases receiving stable dose hormone replacement therapy), and / or any other toxicity related to previous anti-cancer treatment (except immune related toxicity) did not return to ≤ grade 2, except hair loss.
- Human immunodeficiency virus (HIV) seropositive or history of HIV infection or other acquired immunodeficiency diseases.
- Long-term use of antiviral drugs, including hepatitis B (HBsAg positive and HBV DNA equal to 2000 IU/ml at the same time, and excluding hepatitis or other causes of hepatitis), hepatitis C (at the same time to meet the anti HCV antibody positive, and HCV-RNA fruit is greater than the lower limit).
- Uncontrolled systemic diseases, such as cardiovascular and cerebrovascular diseases and diabetes.
- History of organ transplantation or stem cell transplantation.
- Cardiac insufficiency (patients classified as III-IV according to NY-HA of New York Heart Association).
- Lung disease (such as shortness of breath during rest or slight activity or oxygen supplement for any reason).
- Other basic diseases which would interfere with the diagnosis of the disease, or might potentially cause serious complications
- Other serious infections before administration
- Alcohol addicts or history of drug abuse.
- History of neurological or mental disorders, such as epilepsy, dementia, poor compliance, or peripheral nervous system disorders.
- Pregnancy or lactation, or expected pregnancy or childbirth during the trial period.
- Allergic to study drug or have a history of allergic reaction to the main and auxiliary materials of any dosage form in the study drug.
