You may qualify if…

• Participants may enter the study only if they meet all the following criteria:
• Male or female, aged ≥18 years at the time of signing the ICF.
• The participants will need to meet the following criteria:
• Participants with a histologically confirmed diagnosis of NMIBC (Ta, T1 and/or Cis).
• During the study, the participants must voluntarily comply with the study-specified cystoscopy, urine cytology and randomized biopsy.
• All toxicities caused by prior radiotherapy, chemotherapy or other treatments have recovered to Grade ≤1 (CTCAE 5.0) (except for alopecia), including but not limited to urinary tract infection, urinary tract irritation, and macroscopic hematuria; participants with Grade >1 anti-neoplastic treatment-related toxicities during the screening period may be enrolled after discussion of the investigators and the sponsor.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2.
• Expected survival ≥24 weeks.
• Laboratory test values meeting the following requirements :
• Hematology ANC≥1.5×10\^9/L. PLT count ≥75×10\^9/L. Hemoglobin (HGB) ≥90 g/L.
• Renal function Creatinine clearance ≥60 mL/min (based on Cockcroft-Gault equation for calculation)
• Hepatic function Serum total bilirubin (TBIL) ≤1.5×ULN. Asparate aminotransferase (AST) and alanine transaminase (ALT) ≤2.5×ULN Serum ALB ≥30 g/L.
• Coagulation function International normalized ratio (INR) or prothrombin time (PT) ≤1.5×ULN. Activated partial thromboplastin time (aPTT) ≤1.5×ULN.
• For women of childbearing potential (WOCBP), the serum pregnancy test prior to the first dose must be negative and the potential participant must promise to use medically acceptable and effective methods of contraception. after signing the ICF until at least 6 months after the last dose.
• Male participants of child-bearing potential must agree to use medically acceptable and effective methods of contraception after signing the ICF until at least 6 months after the last dose; in addition, male potential participants must agree not to donate sperm during this period.
• Participants who understand and voluntarily sign the written ICF and are willing and able to comply with all trial requirements.

You may not qualify if…

• Participants meeting any of the following criteria will not be allowed to participate in this study:
• Participants meet the following criteria:
• Concurrent or prior history of muscle-invasive (muscularis propria) or metastatic bladder cancer.
• Urothelial carcinoma of the upper genitourinary tract or prostatic urethra within 24 months prior to investigational product.
• Having received chemotherapy, biotherapy, endocrine therapy, targeted therapy, immunotherapy, investigational product or other anti-neoplastic therapies within 4 weeks prior to investigational product.
• Having received radiotherapy within 2 weeks prior to investigational product.
• Planning to receive any anti-neoplastic therapy other than the investigational products during this study.
• A history of allergic reactions to HSV-1, IL-12, or anti-PD-1 antibodies or biological components similar to them, or known allergic reactions to any component of the T3011 formulation.
• A history of brain metastasis or imaging-confirmed brain metastasis , leptomeningeal disease, or spinal cord compression.
• Concurrent or prior history of other malignancies than that treated in this study.
• History or evidence of high-risk cardiovascular diseases, including but not limited to:
• Serious cardiac rhythm or conduction abnormalities.
• Acute myocardial infarction, unstable angina, or stroke, etc., developing within 6 months prior to the first dose of the investigational products.
• Coronary angioplasty or stenting within 6 months prior to the first dose of the investigational products.
• New York Heart Association (NYHA) criteria-defined cardiac function > Class II; echocardiogram-documented cardiac valve morphological abnormalities (Grade ≥2).
• Left ventricular ejection fraction (LVEF) ˂lower limit of normal (LLN) of the study site, or ˂ 50% if no LLN is set at the site.
• Poorly controlled blood pressure .
• The following prior or concurrent immune disorders that in the investigator's opinion would pose unpredictable risks to the participants:
• Immune-related pneumonia or other immune-related adverse reactions of Grade ≥3 developing with prior immunotherapy (including but not limited to PD-1/PD-L1).
• Concurrent active immune diseases requiring treatment with systemic immunosuppressants (excluding autoimmune diseases not requiring intervention such as vitiligo and diseases treatable by other alternative drugs such as hypothyroidism that is treated with thyroid hormone replacement therapy originally), or concurrent immune diseases requiring treatment with systemic immunosuppressants that have the potential to recurrence (e.g., systemic lupus erythematosus).
• Other concurrent diseases require treatment with systemic immunosuppressants.
• Unexplainable fever >38.5℃ during the screening or on the day of treatment (fever judged as tumor-induced by the investigator is eligible for enrollment) that in the investigator's opinion will affect the participation in this trial or interfere with the efficacy assessment.
• The following persistent or active infections: human immunodeficiency virus (HIV) antibody-positive, hepatitis B surface antigen [HBsAg] positive with HBV DNA level ≥2000 IU/mL, hepatitis C virus (HCV) antibody positive with detectable HCV RNA, and other active infections requiring systemic treatment.
• Prior history of splenectomy or organ transplantation.
• Having previously received treatment with oncolytic virus (e.g., T-VEC, CG0070).
