Overview
The objective of the study is to construct a noninvasive approach using 68Ga-labeled bicyclic peptide radiotracer to detect the matrix metalloproteinase 14 (MMP14, MT1-MMP) expression of tumor lesions in patients with solid tumors and to identify patients benefiting from MMP14 targeting treatment.
Description
Analysis plan: 1. Recruit 3-5 participants to analyze preliminary pharmacokinetic/first-in-human dose (FIH), major organ distribution, and tumor uptake information via whole-body PET/CT imaging; 2. Recruit 20-30 participants to analyze in vivo safety and tumor targeting information; 3. Recruit all participants for a final summary.
Eligibility
Inclusion Criteria:
- Malignant melanoma, glioma, lung cancer, colon cancer, pancreatic cancer, gastric cancer, breast cancer, liver cancer, etc., confirmed by histopathology or cytology;
- age ≥18 and ≤75 years old, male or female;
- ECOG score 0 or 1;
- expected survival time ≥6 months;
- There was at least one measurable target lesion according to RECIST1.1 criteria, and biopsy could be performed within one month before and after PET scan, and the patient could provide 2-3 lesion tissue slides;
- Women of childbearing age (15-49 years) must have had a negative pregnancy test within 7 days before starting testing; Women and men of childbearing potential must agree to use effective contraception to avoid pregnancy during the study and for 3 months after the examination;
- patients recommended by clinicians to undergo PET/CT examination for tumor staging;
- The subjects could fully understand and voluntarily participate in this experiment, and signed an informed consent.
Exclusion Criteria:
