August 29, 2026 updated by: Meng LIU, Peking University First Hospital

Clinical Study of Glypican-3 (GPC3)-Targeted Novel Probe 18F-X12 for the Diagnosis of Hepatocellular Carcinoma (HCC)

This is a diagnostic study. This clinical trial aims to evaluate the diagnostic performance and safety of the novel radiotracer 18F-X12 in patients with hepatocellular carcinoma (HCC), and to provide evidence supporting a new approach for its early diagnosis, accurate staging and recurrence assessment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Patients aged ≥ 18 years old.
  • Patients fully understand the trial requirements, participate in the study voluntarily, and provide written informed consent.
  • Meet either of the following two conditions:
  • Patients with highly suspected hepatocellular carcinoma (HCC) (hepatic space-occupying lesion of undetermined nature on imaging examination) or pathologically confirmed HCC, with no prior systemic therapy (including immunotherapy, chemoradiotherapy, targeted therapy, etc.) or suspected tumor recurrence after previous treatment, and able to independently cooperate with relevant examinations.
  • Patients with clinically diagnosed HCC who have received 18F-FDG positron emission tomography/computed tomography (PET/CT) for clinical staging or post-treatment restaging, and able to independently cooperate with relevant examinations.

Exclusion Criteria:

  • Patients with severe non-malignant diseases that may interfere with study objectives, or impair subject safety and study compliance, including but not limited to psychiatric disorders, infectious diseases, autoimmune diseases, and metabolic diseases.
  • Pregnant or lactating females.
  • Subjects who are unable to understand the examination procedure or cannot cooperate with trial-related examinations and operations.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 18F-X12 PET/CT
The objective is to evaluate the diagnostic efficacy and safety of the novel radiotracer 18F-X12 in patients with hepatocellular carcinoma (HCC).
Diagnostic test: 18F-X12 PET/CT
Participants will receive a single intravenous injection of 18F-X12, and undergo PET/CT imaging approximately 120 minutes after radiotracer administration.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of Adverse Events [Safety and Tolerability]
Time Frame: 24 hours after the injection of 18F-X12
Clinical symptoms and adverse events (e.g., fever, rash, hypoglycemia) will be monitored within 24 hours after injection, and graded according to the Common Terminology Criteria for Adverse Events (CTCAE, Version 6.0).
24 hours after the injection of 18F-X12
To evaluate the diagnostic efficacy of 18F-X12 PET/CT for hepatocellular carcinoma (HCC).
Time Frame: From study completion to 1 month after completion
We calculated the diagnostic sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 18F-X12 positron emission tomography (PET) imaging for patients with hepatocellular carcinoma (HCC), with histopathological results as the diagnostic gold-standard reference.
From study completion to 1 month after completion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Standardized Uptake Values of Primary and Metastatic Lesions on ¹⁸F-X12 PET/CT versus ¹⁸F-FDG PET/CT
Time Frame: From the date of study completion up to 1-month post-completion
Comparison of the maximum standardized uptake value (SUVmax) and mean standardized uptake value (SUVmean) of primary and metastatic lesions between 18F-X12 positron emission tomography/computed tomography (PET/CT) and 18F-fluorodeoxyglucose (FDG) PET/CT.
From the date of study completion up to 1-month post-completion
Correlation between 18F-X12 Uptake and GPC3 Pathological Expression
Time Frame: From the date of study completion up to 1-month post-completion
We evaluated the correlation between uptake parameters derived from 18F-X12 positron emission tomography/computed tomography (PET/CT) and Glypican-3 (GPC3) expression levels measured by immunohistochemistry (IHC) in tumor tissue samples.
From the date of study completion up to 1-month post-completion
