Clinical Evaluation of [68Ga]Ga-FFD PET Imaging in Healthy Volunteers and Patients With Solid Tumors

12. juli 2026 opdateret af: Union Hospital, Tongji Medical College, Huazhong University of Science and Technology

A Single-Center, Prospective, Open-Label Clinical Study to Evaluate the Safety, Biodistribution, Radiation Dosimetry, and Diagnostic Performance of [68Ga]Ga-FFD PET Imaging in Healthy Volunteers and Adult Patients With Solid Tumors

This is a prospective, single-center, open-label clinical study designed to evaluate the safety, biodistribution, radiation dosimetry, and diagnostic performance of [68Ga]Ga-FFD PET imaging. The study consists of two cohorts: healthy volunteers and adult patients with histologically or clinically confirmed malignant solid tumors. Healthy volunteers will undergo serial PET imaging to evaluate tracer biodistribution, pharmacokinetics, and radiation dosimetry. Patients will undergo [68Ga]Ga-FFD PET imaging in addition to standard-of-care ^18F-FDG PET imaging for assessment of lesion detection and diagnostic performance. Safety will be evaluated through adverse event monitoring, vital signs, laboratory tests, physical examinations, and electrocardiography. Diagnostic performance will be assessed using histopathology, conventional imaging, and clinical follow-up as the reference standard.

Detaljeret beskrivelse

This first-in-human study evaluates the clinical performance of [68Ga]Ga-FFD, a novel PET radiotracer for molecular imaging of malignant tumors. Healthy volunteers will undergo serial whole-body PET imaging after a single intravenous administration of [68Ga]Ga-FFD to characterize biodistribution, organ uptake, pharmacokinetics, and radiation dosimetry. Adult patients with malignant solid tumors will undergo [68Ga]Ga-FFD PET/CT and standard-of-care ^18F-FDG PET/CT imaging. Diagnostic performance, including lesion detection and patient-based diagnostic accuracy, will be compared between the two imaging modalities. Radiation dosimetry will be estimated using time-activity curves and the OLINDA/EXM software based on the MIRD methodology. Safety assessments will include adverse events, laboratory evaluations, electrocardiography, physical examinations, and vital signs.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: [68Ga]Ga-FFD PET Imaging
Participants will receive a single intravenous administration of [68Ga]Ga-FFD followed by serial whole-body PET/CT imaging. Healthy volunteers will undergo imaging for biodistribution and radiation dosimetry evaluation, while patients with malignant solid tumors will additionally undergo standard-of-care ^18F-FDG PET/CT imaging for assessment of diagnostic performance.
Medicin: [68Ga]Ga-FFD
For Cancer patients, [68Ga]Ga-FFD is a gallium-68-labeled PET radiotracer administered as a single intravenous injection at approximately 185 MBq (5 mCi ±10%) for molecular imaging. Whole-body PET/CT imaging will be performed at approximately 0.5 and 2 hours after administration to evaluate tracer biodistribution, radiation dosimetry, safety, and diagnostic performance.

Tidsramme
Visual and standardized uptake values assessment of lesions and biodistribution
Tidsramme: one month
PET images will be independently reviewed by at least two experienced nuclear medicine physicians who are blinded to each other's interpretations. Histopathological findings, when available, together with clinical and imaging follow-up, will serve as the reference standard for lesion verification. Both visual and semiquantitative analyses will be performed for each participant. Semiquantitative analysis will include measurement of the maximum and mean standardized uptake values (SUVmax and SUVmean) of tumor lesions and major normal organs at each imaging time point. Lesion detection, tracer biodistribution, tumor-to-background ratios, and image quality will also be evaluated.

Tidsramme
Incidence of Treatment-Emergent Adverse Events
Tidsramme: From administration of [68Ga]Ga-FFD through 7 days after PET imaging.
Safety will be evaluated by assessing the incidence, severity, and relationship of treatment-emergent adverse events (TEAEs), together with changes in vital signs, physical examinations, laboratory tests, and 12-lead electrocardiograms following administration of [68Ga]Ga-FFD.
From administration of [68Ga]Ga-FFD through 7 days after PET imaging.
Biodistribution of [68Ga]Ga-FFD
Tidsramme: Approximately 0.5 hours and 2 hours after tracer administration.
Percentage of injected dose (%ID), SUVmean, and residence time in major organs and tissues will be measured at each imaging time point. Time-activity curves will be generated for quantitative biodistribution analysis.
Approximately 0.5 hours and 2 hours after tracer administration.
