The serum or urine human chorionic gonadotropin (HCG) examination must be negative within 7 days before the study was enrolled.

Exclusion Criteria:

  1. Any active autoimmune disease or history of autoimmune disease (such as, but not limited to, interstitial pneumonia, uveitis, enteritis, hepatitis, arthritis, nephritis, pituitary inflammation, hyperthyroidism, hypothyroidism, etc.); Patients with vitiligo or asthma in childhood, and still need medical intervention in adult; Patients need bronchodilators for medical intervention of asthma.
  2. Patients are using immunosuppressive agents, or systemic, or absorbable topical corticosteroid medications to achieve immunosuppressive purposes (doses >10mg/day prednisone or equivalent), which is ongoing 2 weeks before enrollment.
  3. Have received any form of organ transplantation, including allogeneic stem cell transplantation.
  4. Known allergy to macromolecular protein inhibitors or any of the components of ZKAB0
  5. Suffering from other malignant tumors other than this diseases in 5 years except skin basal cell and squamous cell carcinoma or cervical carcinoma in situ.
  6. Central nervous system metastases with clinical symptoms (such as cerebral edema and brain metastases requiring corticosteroid intervention). Previous treatment with brain or meningeal metastasis, such as clinical stabilization (MRI) less than 2 months, or systemic corticosteroid (dose >10mg/day prednisone or equivalent) less than 2 weeks.
  7. Patients with clinical symptoms or heart diseases that cannot be well controlled, such as heart failure above New York Heart Association (NYHA) 2 grade, unstable angina pectoris, myocardial infarction in 1 year, and clinically significant supraventricular or ventricular arrhythmia requiring treatment or intervention, left ventricular ejection fraction < 50% at rest as shown in the ultrasound cardiogram.
  8. Patients who had received radiotherapy, chemotherapy, surgery or molecular targeted therapy before, were given less than 4 weeks or 5 half-life (longer time) after the treatment (if treated with nitrosourea or mitomycin previously, the time interval between the end of chemotherapy and study inclusion was less than 6 weeks); Adverse events caused by previous treatment did not recover to level 1 of CTCAE, except for hair loss.
  9. Active infection, or unexplained fever> 38.5 degrees during screening period or before the first dose of ZKAB001 (subjects with fever from the tumor could be enrolled upon investigator's decision).
  10. Human immunodeficiency virus (HIV) positive, syphilis spirochete positive, untreated active hepatitis.
  11. The patient is participating in other clinical studies or is less than 1 month away from the end of the previous clinical study.
  12. Patients may need to receive other systemic cancer treatment during study period.
  13. Prior therapy with an anti-PD 1, anti-PD L1, or anti-CTLA-4 (Cytotoxic T Lymphocyte Antigen-4) antibody (or any other agents that target immunoregulatory receptor).
  14. Recent history of prophylactic non-cancer vaccination (such as seasonal influenza vaccine and human papillomavirus (HPV) vaccine) within 28 days before screening.
  15. History of mental drug abuse, alcohol abuse or drug abuse.
  16. Pregnant or lactating women.
  17. Any mental condition that prevents the understanding or provision of an informed consent.
  18. It is determined by the investigator that the patient has other factors that may lead to the termination of the study, such as other serious diseases or serious laboratory test abnormalities or other factors that may affect the safety of the subjects, family or social factors that may affect the study data and sample collection.
