Clinical Trial · NCT05126927

A PET Imaging Agent to Assess the Level of Tumor Tissue-infiltrating CD8 + T Cells in Patients With Solid Tumors

Overview

Primary objective To investigate the safety and tolerability profile of 68Ga- NODAGA-SNA006 in patients with solid tumors; To investigate the radiation absorbed dose characteristics of 68Ga-NODAGA-SNA006 in patients with solid tumors; To investigate the distribution profile of 68Ga-NODAGA-SNA006 in patients with solid tumors. Secondary objectives To investigate the optimal administration dose and radiation safety profile of 68Ga-NODAGA-SNA006; To investigate the PET imaging characteristics and high-quality imaging time window of 68Ga-NODAGA-SNA006 in patients with solid tumors; To explore the correlation between PET imaging characteristics of 68Ga-NODAGA-SNA006 binding to CD8 and histological CD8 expression characteristics; To explore peripheral blood T lymphocyte differentiation (CD8, CD4, CD3, etc.) in patients with solid tumors.

Eligibility

Inclusion

  • Imaging results show that at least one tumor lesion can be needle biopsy or surgical treatment to obtain specimens (enhanced CT, enhanced MRI or 18F-FDG PET/CT results are acceptable);
  • Blood pressure measurement \< hypertension grade 1 level (including a history of hypertension, systolic blood pressure \< 140 and diastolic blood pressure \< 90 mmHg by exercise or drug treatment);
  • Basal heart rate 60-100 beats/min (including boundary values);
  • Patients with confirmed solid tumors;
  • Patients with immunohistochemical CD8 results within the past month;
  • Patients who must have at least one image-measurable lesion according to the evaluation criteria for solid tumors (RECISTv1.1);
  • Performance status (ECOG) score 0-1 points (see Appendix 1 for details);

Exclusion

  • Those who have participated in any other clinical trial within 3 months prior to screening
  • Those with known severe allergy to SNA006, similar drugs or excipients. Specialized conditions
  • Patients who have not recovered from a serious infection
  • Those with claustrophobia, emotional instability, acute persistent spasticity or inability to keep both arms up and lying flat for 15-30 minutes
  • Patients with brain metastases.
  • Those with comorbid major diseases or other malignancies (except those that have healed by one year or do not require additional treatment)
  • Those who, in the opinion of the investigator, are not suitable to participate in this clinical study.
  • Patients with drug/alcohol abuse, severe mental disorders
  • Patients who have undergone previous splenectomy or splenic disease such as hypersplenism or splenomegaly
  • Serum virology tests: positive results for any of hepatitis B virus surface antigen, hepatitis C virus antibodies, syphilis-specific antibodies or those who cannot be determined to be negative for human immunodeficiency virus antibodies
  • Those who have extremely poor nutritional status and cannot tolerate the trial
