Multiple Treatments for Skin Tumors
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to evaluate the effectiveness of four existing treatments in reducing skin tumors in individuals with Neurofibromatosis Type 1 (NF1). The treatments being tested include two lasers (1064nm Nd:YAG Laser and 755nm Alexandrite Laser) and two types of injections (Asclera and Kybella). Participants will receive treatments on some tumors, while others will remain untreated for comparison. If a treatment does not shrink the tumors after three visits, participants may switch to the most promising treatment. The trial seeks individuals with NF1 who have visible skin tumors that are easy to photograph and measure. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to contribute to early-stage medical research.
Do I need to stop my current medications for the trial?
The trial protocol does not specify whether you need to stop taking your current medications. However, if you are on antiplatelet or anticoagulant therapy, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that the treatments in this study are generally safe. The 1064nm Nd:YAG laser is safe for various skin types, including darker ones, and often treats skin issues like blood vessel problems without damaging the skin's surface.
The 755nm Alexandrite laser is also considered safe. It addresses skin roughness and redness, though it might temporarily change skin color, such as darkening or lightening.
Asclera, known as polidocanol, has FDA approval for treating small varicose veins. It is mostly safe, but there is a small risk of serious allergic reactions, making medical supervision during treatment important.
Kybella, another FDA-approved treatment, is safe for reducing fat under the chin. Common side effects include swelling and bruising at the injection site. While approved for use under the chin, using it elsewhere might be riskier.
Overall, these treatments have been studied and are generally safe. However, monitoring for any side effects is important, as with any medical treatment.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for skin tumors because they employ innovative methods to target and reduce tumors. The 1064nm and 755nm lasers use specific wavelengths to precisely target hemoglobin in the blood vessels of the tumors, potentially leading to more effective and less invasive treatment. Asclera and Kybella injections offer non-surgical options with unique active ingredients; Asclera uses polidocanol to sclerose blood vessels, while Kybella utilizes deoxycholic acid to break down fat cells. These approaches provide alternatives to traditional surgical and topical treatments, with the potential for faster recovery and fewer side effects.
What evidence suggests that this trial's treatments could be effective for Neurofibromatosis Type 1 Cutaneous Neurofibromas?
Research has shown that the 1064nm Nd:YAG laser, one of the treatments in this trial, holds promise for treating skin tumors. One study found that it completely removed nearly 40% of treated moles and almost completely cleared about 70% of cases. Another treatment option in this trial, the 755nm Alexandrite laser, effectively targets pigmented spots and surface-level skin cancers, significantly reducing skin lesion scores. Asclera, a polidocanol injection included in this trial, achieved total tumor disappearance in 95% of cases. Kybella, another treatment under study, is commonly used to reduce chin fat and has shown improvements in fat reduction, though its use for tumors is less documented. Overall, these treatments have demonstrated varying levels of effectiveness for skin-related conditions.678910

Are You a Good Fit for This Trial?
This trial is for individuals with Neurofibromatosis Type 1 who have skin tumors known as Cutaneous Neurofibromas. Participants should be willing to undergo multiple treatment sessions and allow for a control site on their body to remain untreated for comparison.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive one of four FDA-approved treatments for Neurofibromatosis Type 1 Cutaneous Neurofibromas, with three treatment visits. If minimal improvement is observed, crossover treatment with the most effective option is offered, followed by three additional treatment visits.
Follow-up
Participants are monitored for safety and effectiveness after treatment, with assessments at 1, 2, 5, and if applicable, 6, 7, and 10 months post-treatment.
What Are the Treatments Tested in This Trial?
Interventions
- 1064nm Nd:YAG Laser
- 755nm Alexandrite Laser
- Asclera
- Kybella
Trial Overview
The study tests the effectiveness of four FDA-approved treatments: two types of lasers (1064nm Nd:YAG and 755nm Alexandrite) and injections (Kybella and Asclera). Patients will receive repeated monthly treatments, with an option to switch if there's no improvement after three visits.
How Is the Trial Designed?
2
Treatment groups
Active Control
Injection into up to 50 cutaneous Neurofibromas (for at total maximum of 10 mL injected) with Kybella (1% deoxycholic acid).
A complementary region of cNFs of similar characteristics to the treatment area in the same body region will be selected to serve as an untreated control group.
