Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Voluntary signed informed consent,
• Male or female, aged ≥18 years,
• Predicted survival ≥ 12 weeks;
• Based on the investigator's evaluation (histopathological classification and clinical staging), patients with locally advanced solid tumors (head and neck squamous cell carcinoma, esophageal carcinoma, urothelium carcinoma, cervical carcinoma, etc), whose SOC is concurrent chemoradiation and cannot be surgically removed, are ineligible or refuse the standard chemotherapy.
• The subject has not been given any anti-tumor systemic therapy or radiotherapy for locally advanced solid tumors in the past
• HER2 expression is confirmed by the site: IHC 1+, 2+or 3+;
• At least one measurable lesion according to RECIST 1.1.
• ECOG performance status score of 0 or 1;
• Adequate heart, bone marrow, liver, and kidney functions, which should meet the following standards within 7 days before the study drug is given (based on the normal values of the site) :
• Left ventricular ejection fraction ≥ 50%; Hemoglobin ≥ 9g/dL; Absolute neutrophil count (ANC) ≥ 1.5 × 10\^9/L； Platelets ≥ 100 × 10\^9/L； Serum total bilirubin ≤ 1.5 times the upper limit of normal value (ULN); ALT and AST ≤ 2.5 × ULN； Blood creatinine ≤ 1.5 × ULN or calculate creatinine clearance rate (CrCl) ≥ 50 mL/min according to Cockcroft Fault formula method;
• Female subjects: should be surgically sterilized, postmenopausal, or agree to use a medically approved contraceptive (such as an intrauterine device, contraceptives, or condoms) during study treatment and within 6 months after the end of study, and their blood pregnancy test must be negative within 7 days prior to study enrollment and they must be non-lactating. Male subjects: should be surgically sterile, or agree to use a medically approved contraceptive during study treatment and within 6 months after the end of study;
• Willing and able to comply with the schedules of the trial and follow-up procedures.

You may not qualify if…

• Received anti-tumor therapy before this study, including radiotherapy, target therapy, immunotherapy, and any anti-tumor clinical studies;
• The subject was given a major surgery and did not fully recover within 4 weeks prior to the study;
• Serum virology examination (based on the normal value of the site):
• HBsAg or HBcAb test results are positive, while HBV DNA copy is detected as positive; The HCVAb test result is positive (only when the PCR test result for HCV RNA is negative, can it be selected for this study); The HIVAb test result is positive.
• The subject was given live vaccine within 4 weeks before the study drug is given or planed to receive any vaccine during the study period (except for Covid-19 vaccine);
• Heart failure≥ 3 grade（NYHA）
• Serious arteriovenous thrombotic events or cardiovascular and cerebrovascular accidents, such as deep vein thrombosis, pulmonary embolism, cerebral infarction, cerebral hemorrhage, myocardial infarction, etc., occurred within one year before the study drug is given, except for lacunar cerebral infarction without symptoms or clinical intervention;
• There are active or progressive infections that require systematic treatment, such as active pulmonary tuberculosis;
• There are systemic diseases that have not been controlled stably as judged by the investigator, including diabetes, hypertension, cirrhosis, interstitial pneumonia, obstructive pulmonary disease, etc;
• Active autoimmune diseases that require systematic treatment (such as the use of immunomodulators, corticosteroids, or immunosuppressants) prior to the start of drug administration, allowing for related alternative treatments (such as thyroid hormone, insulin, or physiological corticosteroid replacement therapy for renal or pituitary dysfunction);
• Patients with other malignant tumors within 5 years prior to the start of study administration;
• Previously received other antibody conjugated drug treatments;
• Those who are known to be allergic to recombinant humanized anti HER2-ADC and components;
• Pregnant or lactating women;
