The trial information does not specify whether you need to stop taking your current medications. Please consult with the study team or your doctor for guidance.

What data supports the effectiveness of the treatment Bevonescein for nerve visualization in head and neck surgery?

Research on similar treatments shows that using near-infrared (NIR) fluorophores can help surgeons see nerves more clearly during surgery, reducing the risk of accidental nerve damage. Studies have demonstrated that these fluorophores improve nerve visibility, even when nerves are hidden under tissue, which could lead to better surgical outcomes. ^{1 2 3 4 5}

Is Bevonescein safe for use in humans?

The research articles provided do not contain specific safety data for Bevonescein or its related names in humans. ^{1 2 3 5 6}

How is the REVEAL 475 System treatment different from other treatments for nerve visualization in head and neck surgery?

The REVEAL 475 System is unique because it uses a fluorescent labeling technique to enhance the visibility of nerves during surgery, which can help prevent accidental nerve damage. This system provides real-time visualization of nerves, even those buried beneath tissue, which is not possible with traditional white light imaging. ^{1 3 4 5 6}

What is the purpose of this trial?

This trial is testing a special tool called the REVEAL 475 system that helps surgeons see nerves better during certain neck surgeries. Patients will receive a dye called bevonescein that makes their nerves glow under this tool. This can help surgeons avoid damaging important nerves.

Findings from Research

The novel near-infrared (NIR) nerve-specific fluorophore, LGW01-08, significantly enhances nerve identification during surgery, allowing for the visualization of nerves buried under approximately 3 mm of tissue, which traditional white light imaging cannot achieve.

In laparoscopic swine surgeries using the da Vinci surgical robot, LGW01-08 demonstrated a favorable safety profile with a 10x difference between toxicity and effective imaging doses, supporting its potential for clinical use in fluorescence guided surgery.

The study tested LGW16-03, a nerve-specific fluorophore, on ex vivo human tissues to improve nerve visualization during surgery, showing no significant difference in fluorescence contrast between topical and systemic administration methods.

This research is a crucial step towards clinical application, as it aims to enhance surgical outcomes by reducing iatrogenic nerve injuries through better nerve identification.

A new library of near-infrared (NIR) nerve-binding fluorophores was developed, allowing for precise visualization of peripheral nerves at depths of 2 to 3 mm, which is significantly deeper than what current visible light contrast agents can achieve.

In swine models, these NIR probes successfully highlighted deep lumbar and iliac nerves during laparoscopic surgery, improving the ability to avoid nerve damage and potentially reducing complications associated with surgical procedures.

The new small molecule fluorophore GE3126 significantly improves nerve visualization during surgery, especially in minimally invasive procedures, by enhancing the contrast of small diameter nerves against surrounding tissues.

In preclinical studies, GE3126 showed no major adverse reactions in rats and provided clear nerve imaging in a porcine model within 5 to 10 minutes of injection, maintaining visibility for up to 80 minutes, suggesting it could help prevent nerve damage during operations.

The use of fluorescently labeled nerve binding peptide NP41 during parotid gland cancer surgery in mice improved the identification and preservation of facial nerves compared to traditional white light methods.

Postoperative assessments indicated that facial nerve function was better preserved with fluorescent guidance, suggesting that NP41 can enhance surgical outcomes by reducing the risk of nerve injury.

A novel peptide, FAM-HNP401, was identified through phage display that selectively binds to human nerves, showing a significant increase in fluorescence intensity compared to previous peptides, which could enhance nerve visibility during surgery.

The use of FAM-HNP401 in both fresh human tissue and rodent models demonstrated its potential for improving intraoperative nerve identification, which may help reduce the risk of nerve injury and associated complications during surgical procedures.
