18F-FSPG PET/CT in Diagnosing Early Lung Cancer in Patients With Lung Nodules

April 7, 2025 updated by: Andrei Iagaru

18F-FSPG PET/CT and Integrated Biomarkers for Early Lung Cancer Detection in Patients With Indeterminate Pulmonary Nodules

This phase II trial studies how well 18F-FSPG positron emission tomography (PET)/computed tomography (CT) work in diagnosing early lung cancer in patients with indeterminate lung nodules. PET imaging with an imaging agent called 18F-FDG is often used in combination with a PET/CT scanner to evaluate cancers. Giving 18F-FSPG before a PET/CT scan may work better in helping researchers diagnose early lung cancer in patients with lung nodules.

Detailed Description

PRIMARY OBJECTIVES:

I. Comparison of fluorine F 18 L-glutamate derivative BAY94-9392 (18F-FSPG) accumulation with fludeoxyglucose F-18 (18F-FDG) accumulation to assess whether (4S)-4-(3-18F-Fluoropropyl)-L-Glutamate (18F-FSPG)-PET is better at discriminating between benign and malignant nodules.

SECONDARY OBJECTIVES:

I. To develop and validate early lung cancer detection biomarkers that would directly impact the growing need to integrate imaging and non-invasive molecular diagnostics for indeterminate pulmonary nodules and allow physicians to avoid unnecessary invasive procedures in patients with benign lung disease.

OUTLINE:

Patients receive 18F-FSPG intravenously (IV) and, undergo a PET/CT scan over 30-60 minutes. Within 24 hours-14 days, patients receive 18F-FDG and undergo a second PET/CT scan over 30-60 minutes.

After completion of study, patients are followed up within 24-72 hours.

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.

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

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
Diagnostic Performance Metrics (Sensitivity, Specificity, PPV, NPV, and Accuracy) of Ultrasonography and Capnography for Malignant Lung Nodules
Time Frame: Through study completion, an average of 2 years and 6 months
The diagnostic performance of ultrasonography and capnography in detecting malignant lung nodules was assessed using sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. Sensitivity and specificity were calculated to determine the ability to correctly identify malignant and non-malignant nodules, respectively. Results were compared to a predefined threshold of 75%, with all percentages reported as proportions of the total number of nodules analyzed. Confidence intervals were calculated for each metric to ensure precision and reliability in the estimates.
Through study completion, an average of 2 years and 6 months

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
Improvement in Predictive Accuracy of Lung Nodule Diagnosis Using the C Statistic (Area Under the Curve, AUC)
Time Frame: Through study completion, an average of 2 years and 6 months
The predictive accuracy of the lung nodule diagnosis model was assessed using the C statistic, also referred to as the area under the receiver operating characteristic (ROC) curve (AUC). Improved performance was defined as a statistically significant increase (p < 0.05) in the C statistic, determined using the DeLong test for comparing correlated ROC curves. The Mann-Whitney U test was also used to compare the distributions of the C statistic between diagnostic methods. Results are reported as the mean C statistic with 95% confidence intervals for each diagnostic method.
Through study completion, an average of 2 years and 6 months
