5T4 Targeting Nanobody Probe for PET Imaging in Solid Tumors
Preparation of 5T4 Tumor Novel Target Nanobody PET Probe and Clinical Translation in Lung Cancer
This study aims to evaluate a novel 5T4 targeted nanobody PET imaging tracer, 68Ga-MY, for the detection and evaluation of solid tumors.
The 5T4 oncofoetal antigen is considered a valuable tumor-associated antigen, which is expressed in many different cancers, but is rarely expressed in normal adult tissues. And cell surface expression of 5T4 is an important property for antibody-targeted therapies. It has been shown that 5T4 is expressed on tumour-initiating cells (TICs) and associated with worse clinical outcome. Moreover, decreased adherence due to 5T4 expression may be associated with cancer spread.
In this single-center, open-label, self-controlled study, approximately 20 patients with suspected or confirmed solid tumors will undergo PET/CT imaging using 68Ga-MY. The imaging results will be compared with 18F-FDG. The study will assess tracer uptake in tumor lesions and compare diagnostic performance between imaging methods. The results may help determine whether 68Ga-MY PET/CT can improve tumor detection, staging, and clinical evaluation in patients with solid tumors.

Experimental: 68Ga-MY PET Imaging
All study participants will be allocated to this arm (single-arm study).Study participants will undergo 68Ga-MY PET/CT scans.After the participant rests quietly for 40 minutes or 1 hour, whole-body imaging of the head and torso will be performed using a United Imaging uEXPLORER Whole-Body PET/CT scanner at 1 h, 2 h, and 3 h post-injection.
The scan range will cover from the vertex to the upper third of the thighs.
Participants who required a dynamic scan underwent a 40-min serial scan after injection of 68Ga-MY.
PET/CT static imaging was performed at 2 h and 3 h after injection.
|
Alle Studienteilnehmer werden einem 18F-FDG-PET/CT-Scan unterzogen.
68Ga-MY is an investigational tracer, and all participants will undergo 68Ga-MY scanning.

Radiation Dosimetry of 68Ga-MY
Zeitfenster: 1. From the start of drug administration to 14 days after injection 2.Dynamic PET/CT scanning from 0 to 40 minutes post-injection, followed by static scans at 1 hour, 2 hours, and 3 hours post-injection. 3.Prior to each patient injection.
|
Radiation Dosimetry Organ-absorbed doses (mGy/MBq) and effective dose (mSv/MBq) calculated from PET/CT data using OLINDA/EXM software based on the MIRD schema.
Organs assessed include, but are not limited to, the liver, spleen, kidneys, lungs, heart, bone marrow, and urinary bladder.

Standardized Uptake Value (SUV)
Zeitfenster: 1. From the start of drug administration to 14 days after injection 2.Dynamic PET/CT scanning from 0 to 40 minutes post-injection, followed by static scans at 1 hour, 2 hours, and 3 hours post-injection. 3.Prior to each patient injection.
|
Parameters of SUV The maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean) and tumor/background ratio (SUVR) of 68Ga-MY in target lesions were observed.
SUVR was calculated as the SUVmax of the target lesion divided by the SUVmean of the reference normal tissue.
