• Prior organ allograft transplantations or allogeneic hematopoietic stem cell transplantation;
• Received live attenuated vaccine within 4 weeks before screening;
• Malignant tumors other than the target tumor within 3 years prior to screening, except for the following: malignant tumors that have received radical treatment and no known active disease within ≥ 3 years prior to enrollment;

Más betegség

  • New York Heart Association (NYHA) stage III or IV congestive heart failure; Myocardial infarction or coronary artery bypass grafting (CABG) within 6 months before enrollment; Clinically significant ventricular arrhythmia, echocardiography showed cardiac ejection fraction<50%,

Egyéb

• Pregnant, lactating, or breastfeeding females;
• Active/symptomatic central nervous system metastases or meningeal metastases at the time of screening; subjects with brain metastases who have been treated must be confirmed to have no imaging evidence of progression ≥ 4 weeks after the end of treatment before they can be enrolled;
• Vaccination within 14 days of study enrollment;
• Other investigators deem it inappropriate to participate in the study.

• Ability to understand and sign a written informed consent documen；
• Age ≥18 years old, male or female；
• Histopathological confirmed advanced or metastatic solid tumors failed to at least second-line treatment or initially diagnosed advanced/metastatic solid tumors that have no NCCN guideline recommended standard first-line therapy；
• Histopathology or cytology (paraffin section or fresh biopsy tumor tissue specimen) diagnosed as advanced/metastatic solid tumor (positive tumor CD70 expression (tumor CD70 positive (IHC 2+) confirmed by histology or pathology));
• At least one measurable lesion at baseline per RECIST version 1.1；
• The expected survival time is more than 12 weeks;
• ECOG 0-1 points;
• The function of important organs is basically normal:Hematopoietic function:
  • Hematopoietic function: neutrophils ≥ 1.5×109/L, platelets ≥ 90×109/L, hemoglobin ≥ 90g/dL;
  • Renal function: serum creatinine≤1.5×ULN;
  • WBC≥3.0×109/L,
  • Liver function: Total bilirubin ≤ 1.5×ULN(Except Gilbert syndrome), extrahepatic metastasis：ALT and AST ≤ 3.0×ULN (Nonhepatic metastasis：it can be relaxed to ≤ 5.0×ULN);
