What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new dye-labeled particle to help doctors see cancerous lymph nodes during surgery in patients with head and neck cancer. The particles are injected around the tumor and light up under a special camera, making it easier to identify affected areas. This method aims to improve current imaging techniques by using recent innovations in imaging technology.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

Is the use of silica nanoparticles for imaging in head and neck cancer safe for humans?

Research on silica nanoparticles, including cRGDY-PEG-Cy5-C dots, shows they have good biocompatibility (they are not harmful to living tissue) and have been safely used in studies for imaging and targeting cancer cells. These studies suggest that they are generally safe for use in humans, although more research is needed to confirm this across different conditions. ^{1 2 3 4 5}

How do silica nanoparticles differ from other treatments for head and neck cancer?

Silica nanoparticles are unique because they are designed to improve cancer imaging by enhancing tumor border definition during surgery, using fluorescent dyes and antibodies to target specific cancer cells. This approach differs from traditional treatments by focusing on precise imaging rather than directly treating the cancer, potentially leading to more accurate surgical outcomes. ^{1 3 6 7 8}

What data supports the effectiveness of the treatment cRGDY-PEG-Cy5.5-C dots for head and neck cancer imaging?

Research on similar silica nanoparticles shows they can enhance tumor imaging by specifically binding to cancer cells, which helps in better defining tumor borders during surgery. ^{1 2 3 8 9}

Are You a Good Fit for This Trial?

This trial is for adults with newly diagnosed or recurrent melanoma, oral cavity squamous cell carcinoma, and skin squamous cell carcinoma needing lymph node mapping. Participants must use birth control if applicable and have normal organ function as determined by the physician. Those who've had recent heart issues, uncontrolled infections, or are pregnant/breastfeeding cannot join.

Inclusion Criteria

My melanoma diagnosis was confirmed through tissue examination at MSKCC.

I was recently diagnosed and had a lump removed for testing.

My heart is healthy according to my doctor's evaluation.

Exclusion Criteria

Known pregnancy or breast-feeding

I do not have severe health issues that would prevent me from taking the treatment.

What Are the Treatments Tested in This Trial?

Interventions

• cRGDY-PEG-Cy5.5-C dots

Trial Overview The study tests a new imaging agent called cRGDY-PEG-Cy5.5-C dots in 67 patients to see if it can better identify cancerous lymph nodes during surgery compared to standard scans. This agent isn't FDA-approved yet and won't be used for treatment but may inform future research.

How Is the Trial Designed?

Group I: Phase 2 - Head and Neck Cancer Experimental Treatment 1 Intervention

Patients with early oral cavity squamous cell carcinoma, and prior to standard of care wide local resection of the primary tumor and elective neck dissection, will receive a locally-administered, peritumoral injection of fluorescent cRGDY-PEG-Cy5.5-C dots (0.25 - 1 ml) around the primary lesion while under standard-of-care anesthesia for identification of optically-avid SLNs and to assess for metastatic disease. After completion of the neck dissection, nodal specimens will be examined ex vivo for fluorescence signal. Any fluorescent and non-fluorescent nodes will be compared to determine the true positive and false positive rates for cancer detection in this pilot study. No change in standard of care surgical practice will occur.

Published Research Related to This Trial

Silica nanoparticles, specifically Ru@SiO2-OH and Ru@SiO2-NH2, showed long-term intracellular persistence in head and neck squamous cell carcinoma (HNSCC) cells without affecting cell proliferation or morphology, suggesting potential for chronic therapeutic applications.

The study indicates that these nanoparticles are internalized through specific pathways and accumulate in organelles, but further research is needed to understand their complex endocytotic mechanisms and optimize their use in HNSCC treatment.

Ultra-small NaYF4:Nd3+/NaGdF4 nanocrystals coated with manganese dioxide (usNP-MnO2) show promise for improving oxygen levels in head and neck squamous cell carcinomas (HNSCC) by modulating tumor hypoxia.

The study utilized dual modality imaging (MRI and photoacoustic imaging) to successfully visualize nanoparticle delivery and increased oxygen saturation in tumor models, indicating a potential method for selecting patients who could benefit from these hypoxia-modifying therapies.

The study demonstrated that 100 nm theranostic nanoparticles can enhance radiation therapy for head and neck squamous cell carcinoma, showing reduced tumor growth and lung metastasis in rat models.

These nanoparticles provide both imaging capabilities and therapeutic benefits, allowing for better radiation therapy planning and improved treatment efficacy, as evidenced by their optimal tumor uptake and effectiveness in reducing tumor size.

The study developed a new imaging technique using dual-modal near-infrared II (NIR II) luminescence and T1 magnetic resonance imaging (MRI) that targets the cMet receptor, which is overexpressed in head and neck squamous cell carcinomas (HNSCCs).

This innovative approach allows for better visualization and accumulation of imaging agents in HNSCC tumors, potentially leading to more accurate and sensitive early detection of this common cancer.
