- Ages 12 to 17 years
- All sexes
- No healthy volunteers
- Child
Who may be able to join
- 1. Male and female children (12 - 17 years of age) with a primary diagnosis, or a high clinical suspicion of a solid tumor with metastasis to the lung warranting surgery based on CT/PET or other imaging 2. Are scheduled to undergo surgical resection for suspected metastasis 3. Female subjects of childbearing potential (including those less than 2 years postmenopausal) agree to use an acceptable form of contraception from the time of signing informed consent until 30 days after infusion of ICG. Male subjects who are are sexually active (and capable of producing sperm) with a partner that could become pregnant, must agree to use an acceptable form of contraception from the time of signing informed consent until 30 days after infusion of ICG.
Who cannot join
- 1. Any medical condition that in the opinion of the investigators could potentially jeopardize the safety of the subject 2. History of anaphylactic reactions to ICG.

Impaired liver function defined as values > 3x the upper limit of normal (ULN) for alanine aminotransferase (ALT),aspartate aminotransferase (AST), or alkaline phosphatase (ALP), or >2x ULN for total bilirubin except in subjects with Gilbert's syndrome. For subjects with Gilbert's syndrome, total bilirubin levels exceeding 3 mg/dL will be excluded. 6.

About this study
Subjects will undergo infusion of 5 mg/kg indocyanine green, ICG ("TumorGlow") intravenously up to 5-days prior to surgery. Then, during the surgical procedure the next day, the subjects will undergo standard-of-care surgery. During the surgery, the fluorescence from the tumor will be used to localize lesions and ensure the entire tumor has been removed, as well as locate any un-expected tumors. The goal of this protocol is to evaluate safety and collect initial efficacy data using indocyanine green with NIR fluorescence imaging in a pediatric patient population undergoing pulmonary metastatectomy.
Read the detailed description
This is a phase 1 single dose, open-label study to determine the safety of a single 5 mg/kg dose of ICG (TumorGlow) used with Near Infrared (NIR) fluorescent for pediatric subjects with suspected metastatic sarcoma to the lung scheduled to undergo thoracic surgery per CT/PET or other imaging based on standard of care.
Following the screening visit to confirm eligibility, subject assent and parental/legal guardian consent for enrollment will be obtained prior to commencement of any study procedures. The screening period will be up to 60 days prior to ICG infusion. All subjects enrolled will be infused with 5 mg/kg ICG intravenously up to 5-days prior to the planned surgery (Day 0).
After ICG infusion is completed (Day 0), subjects during the surgery will undergo white light evaluation and/or palpation, and the number and the location of all suspicious nodules and lesions identified in this step will be recorded as such following the study procedure guideline as described in  (Day 1). Following white light assessment, but prior to any surgical removal of lesions/nodules, subjects will undergo assessment with NIR fluorescent light imaging to localize any lesions or nodules.
All identified lesions will be removed as determined by the surgeon. All removed lesions identified either using white light, NIR imaging or both will be documented as such and examined back table for fluorescence under NIR imaging including margin status. Positive margins are defined as fluorescent areas identified within (less than or equal to) 5mm of the inside staple line by back table measurement. Following the resection and prior to closing the subject, the field will be illuminated with the imaging system again to detect and remove any remaining fluorescence positive nodules. All specimens removed after the back table examination will be sent to pathology for evaluation including margin status by a pathologist that is blinded to the fluorescent status of lesions or nodules.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
To assess the safety and tolerability of intravenously infusion of a single dose 5 mg/kg of ICG; 2. To assess the safety and tolerability of using high dose (5 mg/kg) ICG used with Near Infrared (NIR) fluorescent imaging when used with ICG in subjects undergoing pulmonary metastasectomy. Safety will be assessed by the incidence of AEs and SAEs coded using MedDRA. Results will be summarized as the number and percentage of participants with events, categorized by preferred term, system organ class, severity grade, attribution, and timing relative to infusion and surgery. AE rates will be reported with one-sided 90% exact confidence intervals and compared against a 25% unacceptable safety threshold.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing ICG INFUSION 5MG/KG in people with Sarcoma Metastatic, run by Abramson Cancer Center at Penn Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Peter Mattei, MD ((215)-590-2730, mattei@email.chop.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
