An Investigational Scan (Me-4FDG PET/CT) for the Detection of Sodium-Glucose Transport for Early Diagnosis of Lung Cancer
What this study is about
The phase I/II trial assess the safety and effectiveness of a new positron emission tomography (PET) test for early diagnosis of lung cancer. This study uses PET and Me-4FDG new glucose tracer (alpha-methyl-4-deoxy-4-\[(18)F\]fluoro-D-glucopyranoside) designed specifically to determine glucose update into cells in the body. PET is a non-invasive imaging method used to detect cancer in patient.
View original scientific description
The phase I/II trial assess the safety and efficacy of a new positron emission tomography (PET) test for early diagnosis of lung cancer. This study uses PET and Me-4FDG new glucose tracer (alpha-methyl-4-deoxy-4-\[(18)F\]fluoro-D-glucopyranoside) designed specifically to determine glucose update into cells in the body. PET is a non-invasive imaging method used to detect cancer in patient. Me4FDG is a radioactive glucose tracer used in PET to locate cells in the body taking up glucose by SGLT2. SLGT2 is a sodium glucose transport protein that accumulates glucose in some cells, e.g. kidney cells and tumors. This study may help researcher determine how effective PET with ME4FDG tracer works in detecting lung cancer.

Primary outcome measures
Sensitivity of Alpha-methyl-4-deoxy-4-[(18)F]fluoro-D-glucopyranoside (Me-4FDG) positron-emission tomography (PET) scans
Time frame: within one month of surgery or biopsy
Will be determined by calculating the standardized uptake value (SUV) in the lesions and the contrast to noise ratio (CNR) relative to an area of normal lung surrounding the lesion, and evaluated by assessing the percentage of patients with a pathologic diagnosis of lung cancer that results positive at Me-4FDG PET scans.
Specificity of Me-4FDG for lung cancer
Time frame: within one week of experimental PET/CT scan
Will be estimated by the percentage of Me-4FDG negativity in lung nodules that have been determined radiologically and/or clinically to be benign with a lung-RAD (Lung Imaging Reporting and Data System), score 1-3.
Optimal combination of sensitivity and specificity
Time frame: within one week of experimental PET/CT scan
Will combine SUV and CNR cut-points that yield the optimal combination of sensitivity (positivity within the adenocarcinoma group) and specificity (negativity with the benign group). Optimality will be based on the cut-points that maximize the Youden index (sum of the sensitivity plus specificity). Based on the combined cut point, will construct 95% confidence intervals for the sensitivity and specificity.
Incidence of adverse events of Me-4FDG
Time frame: From baseline to one week after Me-4FDG administration
Will tabulate the number of adverse events (AEs) and the severity of adverse events (SAEs) for the overall population as well as within subjects.
Efficacy of Me-4FDG in diagnosing lung cancer
Time frame: within one week of the experimental PET/CT scan
Will be evaluated by measuring the percentage of test positivity in patients with a pathological diagnosis of lung cancer.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age \> 18 years
- Lung nodule \>= 1 cm visualized by CT imaging
- CANCER ARM: Pathologically confirmed lung adenocarcinoma. For patients who are surgical candidates, the pathologic report on the surgical specimen will confirm the diagnosis. For patients who are not surgical candidates, the enrollment will be contingent upon a pathologic diagnosis of lung cancer obtained by needle biopsy
- BENIGN ARM: Lung nodules considered to be clinically benign, according to the Guidelines for Management of Incidental Pulmonary Nodules from the Fleischner Society. Will consider "benign" the nodules with a lung-RADS score of 1-3
Exclusion criteria
- Diagnosis of diabetes
- Current treatment with SGLT2 inhibitors or metformin
Where
- Los Angeles, California

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
