An Open-label, Single-arm, Single-center Study to Evaluate the Diagnostic Efficacy of a Novel PET Probe, 68Ga-SFB6-ZN01, in Patients With Malignant Tumors

Sponsor: Zhongnan Hospital

Summary

This study is being done to test a new imaging agent called 68Ga-SFB6-ZN01, which helps visualize tumors using PET/CT scans. The agent attaches to a protein called integrin αvβ6, which is found on the surface of many cancer cells but rarely on normal cells. A total of 98 adults who either have a confirmed cancer diagnosis, are strongly suspected of having cancer, or may have recurrent cancer after previous treatment will be enrolled. Each participant will receive a single injection of 68Ga-SFB6-ZN01 and undergo one PET/CT scan within one week of joining the study. The main goals are: to see how safe the imaging agent is and whether it causes any side effects; to understand how the agent distributes in the body, and how much radiation exposure it gives; to determine how accurately 68Ga-SFB6-ZN01 PET/CT can detect cancerous lesions and correctly stage the disease, using biopsy results or long-term follow-up (≥6 months) as the reference standard; to explore whether the PET signal intensity (e.g., SUVmax) correlates with the expression of integrin αvβ6 in the tumor tissue. No therapeutic treatment is given in this study. Participation involves one imaging visit and follow-up contact. The results will help determine whether this new tracer should be developed further for cancer imaging.
