An observational study in Malignant Tumor, sponsored by First Hospital of China Medical University. Recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-05-18.

Purpose Ephrin type-A receptor 2 (EphA2) is a receptor tyrosine kinase overexpressed in various solid tumors and associated with tumor progression, metastasis, and poor prognosis. However, noninvasive imaging tools for assessing EphA2 expression in vivo remain limited. This study aims to develop a novel 68Ga-labeled EphA2-targeting positron emission tomography (PET) tracer for specific imaging of EphA2-positive malignancies.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Patients with Malignant Tumor
Device: 68Ga- DOTA-EphA2 PET/CT Imaging of Malignant Tumor
Study of the Radioligand 68Ga- DOTA-EphA2 for PET/CT Imaging of Malignant Tumor
Number of Participants With Treatment-Emergent Adverse Events Following ⁶⁸Ga-NOTA-EphA2
Number of participants experiencing treatment-emergent adverse events (TEAEs) after administration of ⁶⁸Ga-NOTA-EphA2, graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Time frame: From tracer administration to 24 hours after tracer injection.
Biodistribution of ⁶⁸Ga-NOTA-EphA2 Measured by Standardized Uptake Value (SUV)
Biodistribution of ⁶⁸Ga-NOTA-EphA2 in normal organs measured by maximum standardized uptake value (SUVmax) and mean standardized uptake value (SUVmean) on PET/CT imaging.
Time frame: From tracer injection to completion of PET/CT imaging (approximately 2-3 hours).
Tumor Uptake of ⁶⁸Ga-NOTA-EphA2 on PET/CT
Tumor uptake of ⁶⁸Ga-NOTA-EphA2 measured by lesion SUVmax, SUVmean, and tumor-to-background ratio on PET/CT imaging.
Time frame: From tracer injection to completion of PET/CT imaging (approximately 2-3 hours).
