Dosing and Tolerability of Deoxycholic Acid Versus Polidocanol in the Treatment of Neurofibromatosis Type 1 Cutaneous Neurofibromas
Study Details
Study Description
Brief Summary
This study will evaluate the tolerability and effectiveness of two treatments in Neurofibromatosis Type 1 Cutaneous Neurofibromas. These treatments are: Kybella and Asclera injection. Each patient will have a treatment and a control site.

Outcome Measures
Primary Outcome Measures
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [3 months after treatment]
Device based treatment will be considered tolerable if <40% of participants treated have a >grade 2 adverse event (AE). A grade 2 AE is defined as an adverse event that requires treatment.
Secondary Outcome Measures
- Treatment specific patient reported outcomes (PRO) [Baseline, 1 day after treatment, 1 week after treatment, 1 month after treatment, 2 months after treatment, 3 months after treatment, 6 months after treatment, 12 months after treatment]
NRS11, modality specific satisfaction assessment
- Clinician reported outcomes (ClinRO) [Baseline, 3 months after treatment, 6 months after treatment, 12 months after treatment]
Clinician assessment of cNF via questionnaire
- Modified SkinDex for cNF [Baseline, 3 months after treatment, 6 months after treatment, 12 months after treatment]
Health-related quality of life measure
Other Outcome Measures
- Rate of healing [Baseline, 3-months after treatment, 6-month after treatment, and 12-months after treatment]
Measured clinically via photography completed by a member of the study team at baseline, 3-month, 6-month, and 12-month post-treatment
- cNF appearance [Baseline, 3 months after treatment, 6 months after treatment, and 12 months after treatment]
Clinically completed 2D and 3D photography Cherry Imaging.
- Biologic effect [3 months after treatment]
Degree of tissue necrosis on skin lesion biopsy at 3 months
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Adult males and females ≥18 years of age
-
Have a diagnosis of NF1 based on germline genetic testing or by meeting ≥ 2 the following criteria:
-
Family history of NF1
-
Six or more light brown ("cafe-au-lait") spots on the skin
-
Presence of two or more neurofibromas of any type, or one or more plexiform neurofibromas
-
Freckling under the arms or in the groin area
-
Two or more pigmented, benign bumps on the eye's iris (Lisch nodules)
-
A distinctive bony lesion: dysplasia (abnormal growth) of the sphenoid bone behind the eye, or dysplasia of long bones, often in the lower leg
-
Tumor on the optic nerve that may interfere with vision
-
Patients must be seeking treatment for cNF
-
Patients must have ≥ 6 paired cNF per modality (3 treated and 3 untreated). cNF should be visible and measure between 2-8mm in size. These must be in areas amenable to treatment and surveillance with digital photography.
-
cNF must be located on the trunk, arms or legs of the patient
-
Able and willing to comply with all visit, treatment and evaluation schedules and requirements
-
Able to understand and provide written informed consent
Exclusion Criteria:
-
Patients who are undergoing other treatment modalities or investigational agents for their cNF lesions
-
Individuals who cannot give informed consent or adhere to study schedule
-
Actively tanning during the course of the study
-
Adverse reactions to compounds of any external agent (e.g., gels, lotions or anesthetic creams) required for use in the study, if no alternative to the said agent exists;
-
Known allergy to injectable anesthetics, polidocanol or deoxycholic acid
-
Those with acute thromboembolic diseases
-
Those with bleeding abnormalities or those who are currently being treated with antiplatelet or anticoagulant therapy
-
Those with dysphagia
-
Women who are pregnant
-
Any condition which, in the Investigator's opinion, would make it unsafe (for the participant or study personnel) to treat the participant as part of this research study
