Using 68Ga-ICAM-1pep PET/CT to assess cancer treatment response

68Ga-ICAM-1pep PET/CT Imaging of Tumor Responses to Radiotherapy in Cancer Patients

Early Phase 1 Interventional Peking University Cancer Hospital & Institute · NCT04596670

This study is testing a new imaging agent to see if it can help predict how well radiotherapy works for people with metastatic cancer.

What this trial studies

This open-label study investigates the predictive value of 68Ga-ICAM-1pep in metastatic cancer patients undergoing radiotherapy. Participants will receive an intravenous injection of 68Ga-ICAM-1pep, and PET/CT imaging will be conducted before and after treatment to evaluate tumor responses. The study aims to identify ICAM-1 as a potential biomarker for predicting the abscopal effect of radiotherapy, which is currently not assessed in clinical practice. Visual and semiquantitative methods will be employed to analyze the imaging results.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-80 with suspected or confirmed lung, esophagus, cervical, or other cancers requiring PET/CT imaging.

Not a fit: Patients who are pregnant, nursing, or have severe hepatic or renal dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new biomarker for predicting treatment responses in cancer patients undergoing radiotherapy.

How similar studies have performed: While the use of ICAM-1 as a biomarker is novel, preclinical studies have shown promising results in predicting radiotherapy effects.
