Detailed Description
Three study drug dose groups were preset, namely 5×10\^10VP、2×10\^11VP and 5×10\^11VP and the "3+ 3" dose escalation method was adopted according to the principle of dose escalation and the sequential...

Exclusion

- Treatment with nitrosoureas or mitomycin C within 6 weeks prior to starting study treatment; Received oral fluorouracil and small molecule targeted drug therapy within 2 weeks or 5 half-lives of the drug (whichever is longer) prior to starting study treatment; Received traditional Chinese medicine treatment with anti-tumor indications within 2 weeks before starting study treatment; Received anti-tumor therapy such as chemotherapy, radiotherapy, biological therapy, endocrine therapy, etc. other than the above-mentioned drugs within 28 days before starting study treatment, or received any other unmarketed investigational drugs;
- Those who have not recovered from the adverse reactions of previous treatment (treatment-related toxicity grade ≤ grade 2, except for alopecia, pigmentation and other tolerable events as judged by the investigator or laboratory abnormalities allowed according to the protocol);
- Other malignant tumors occurred within 5 years before enrollment, except for carcinoma in situ of the cervix that has been effectively resected and does not require continued anti-tumor treatment, low-risk to very low-risk gastrointestinal stromal tumors (primary tumors at any site, tumor size is ≤5cm, and the number of nuclear division images per 50 high-power field ≤5), in situ or early (stage I) breast cancer, basal cell carcinoma of the skin, papillary thyroid carcinoma;
- Those who have undergone any major surgery (except for needle biopsy, etc.) or severe trauma within 4 weeks before the first dose;
- Patients who have been treated with high-dose systemic corticosteroids (prednisone\> 10mg/day or equivalent dose of similar drugs) or other immunosuppressants within 2 weeks before the first dose. In addition to the following conditions: treatment with topical, ocular, intraarticular, intranasal and inhaled corticosteroids; short-term use of corticosteroids for prophylactic treatment, such as the use of contrast agents;
- Congestive heart failure with cardiac function ≥ NYHA class III; Acute myocardial infarction or unstable angina within 6 months prior to dosing; Left ventricular ejection fraction (LVEF) \<50%; Corrected QTc interval (corrected by Fridericia's formula) \> 450 msec for males and \>470 msec for females, or risk factors for torsades de pointes, such as clinically significant hypokalemia, family history of long QT syndrome, or familial history of cardiac arrhythmias (eg, preexcitation syndrome) as judged by the investigator;
