About

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.

Full 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.

Enrollment: 30 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
