Detailed Description

After being informed about the study and potential risks, all patients giving written informed consent will be evaluated to determine eligibility for study entry. Patients will receive an injection of [68Ga]Ga-NOTA-SNA002 (1.0-5.0mCi) in Day1 and will undergo PET/CT scanning to determine uptake of [68Ga]Ga-NOTA-SNA002 in tumor lesions and reference tissues.

    • Number of participants in CTCAE 5.0 Stage 1 or higher with laboratory examination(e.g. WBC, RBC, HB and other laboratory tests) after administration.
  • Immunogenicity Analysis of [68Ga]Ga-NOTA-SNA002
    • Time Frame: 1 month
    • By analyzing anti-SNA002 anti-drug antibody positive rate.
  • Description of biodistribution patterns of [68Ga]Ga-NOTA-SNA002 on PET
    • Time Frame: 1 month
    • Description of biodistribution patterns of [68Ga]Ga-NOTA-SNA002 on PET.

Secondary Measures

    • Time Frame: 12 months
    • SUVmax quantitative analysis in tumors
  • Standard Uptake Value(peak) in tumors
    • Time Frame: 12 months
    • SUVpeak quantitative analysis in tumors
  • Standard Uptake Value(mean) in tumors
    • Time Frame: 12 months
    • SUVmean quantitative analysis in tumors
  • Correlation of [68Ga]Ga-NOTA-SNA002 uptake in biopsied tumors with PD-L1 measurement by immunohistochemistry (IHC)
    • Time Frame: 12 months
    • Analyze [68Ga]Ga-NOTA-SNA002 uptake in biopsied tumors as determined by SUV-based quantitative measures (SUVmax, SUVpeak, SUVmean) with PD-L1 measurement determined by IHC from biopsy samples.
