Inclusion criteria

    1. Age 18 to 75years, male or female.
    1. Phase Ib:With advanced or metastatic malignant solid tumor confirmed by histopathology, the standard treatment fails, or there is no standard treatment plan, or standard treatment is not applicable at this stage, or the patient refuses the standard treatment, or the investigator evaluates the patient who can benefit from this treatment.
  • 3.Phae II: Confirmed by histopathology that it is not feasible to perform complete resection and cannot be connected. Locally advanced (stage IIIB or IIIC) or metastatic (IV) after radical concurrent radiotherapy and chemotherapy Stage) non-small cell lung cancer (NSCLC). Note: For unacceptable radical synchronization/sequencing.Subjects with locally advanced stage IIIB/IIIC of radiotherapy and chemotherapy need to be evaluated by relevant professional doctors. And provide written records to confirm.

    1. Eligible patients with fertility (male and female) must agree that during and at the end of the trial.Use reliable contraceptive methods (hormones or screens) with their partners for at least 6 months after taking the drug.Obstacle law or abstinence); Blood of female patients of childbearing age within 7 days before the first use of the study drug.The pregnancy test must be negative.
  • 11.Subjects must be informed of the study prior to the trial and voluntarily sign a written informed consent form.
