Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
PDT Treatment
Arm Description
Each subject will have either placebo or Levulan Kerastick topical application applied to matched sets of neurofibromas. Each subject will have both sets, in order to serve as his/her own control subject. 16 to 24 hours post study drug treatment, both sets of neurofibromas, Levulan and placebo treated, will be irradiated with red light (630 nm) from an Omnilux Revive light device at 100 mW/cm2 for 1000 seconds (16.7 minutes).
Outcomes
Primary Outcome Measures
Time to disease progression
The time it takes for 50% growth in tumor size over baseline measurements.
Secondary Outcome Measures
Tumor growth rate
Measure tumor size for control and treatment tumors in order to gain insights into tumor growth rates.

5. Study Description
Brief Summary
The investigators wish to determine the time to disease progression for benign neurofibromas treated with Levulan Kerastick topical photosensitizer and red light photodynamic therapy (PDT) in patients with neurofibromatosis type 1 (NF1).
The investigators also wish to measure tumor size for control and treatment tumors in order to gain insights into tumor growth rates.
Detailed Description
Neurofibromas contain a large quantity of fibrous matter, and it is not anticipated that significant reductions in tumor size can be achieved in large, long established, tumors. Cutaneous neurofibromas, which do not usually become apparent until puberty, continue to increase in size and number throughout adulthood. The psychosocial burden of these disfiguring tumors is significant, and the targeted age group (14-30) is at a life period associated with an acceleration in tumor growth. It is for these reasons that the investigators hope to affect the growth rate of less established tumors, in order to prevent or lessen this burden as the patient progresses further into adulthood.
Therefore, the investigators wish to determine the time to disease progression (defined as 50% growth in size over baseline) for benign neurofibromas treated with PDT in patients with neurofibromatosis type 1 (NF1) in subjects aged 14-30.
The treatment will consist of choosing several neurofibromas of similar size, and applying a topical drug called Levulan, or just the topical application alone (a placebo). Within 24 hours of drug treatment, the neurofibromas will be illuminated with red light (both Levulan and placebo). The Levulan is what is known as a photosensitizer, and will be activated by the red light to potentially kill some of the tumor cells. Approximately every 6 months after, for three years, the tumors will be measured by digital photography and ultrasound to see if they are growing more slowly than the ones with the placebo application alone.
