Ranibizumab for Neurofibromas Associated With Neurofibromatosis 1

Participant gender:
All
Summary
The purpose of this research study is to determine if ranibizumab can prevent the growth of neurofibromas. We will also be collecting extra blood and serum samples to help us learn more about NF1. Ranibizumab is a drug that affects the development of blood vessels that feed tumors. It targets a substance in the body called VEGF (Vascular Endothelial Growth Factor). VEGF helps tumors to grow and survive by supporting the growth of blood vessels that bring nutrients to the tumor. VEGF is made by cancerous tumors and also by non-cancerous tumors such as neurofibromas.

iris e) Distinctive bony lesions such as dysplasia of the sphenoid wing or of a long
bone such as the tibia f) Two or more neurofibromas of any type or 1 or more plexiform
neurofibroma g) First degree relative with NF1

another skin tumor b) the lesion must be amenable to measurement with calipers with
minimum dimension of 5mm and maximum dimension of 20mm c)the lesions cannot be located
on the face, scalp, or groin and must be located in an area that can be photographed
d) histologic confirmation of tumor type is not required in the setting of compatible
clinical setting
