Use of RAD001 as Monotherapy in the Treatment of Neurofibromatosis 1 Related Internal Plexiform Neurofibromas (NFitor)
Patients with the genetic disorder neurofibromatosis Type 1 (NF1) are at increased risk of developing tumors of the central and peripheral nervous system. These include plexiform neurofibromas. The conventional treatment of these internal plexiform neurofibromas is surgery. This surgery can be possible on a single and limited tumor. On the other hand these tumors are often surgically intractable due to their multiplicity and their infiltrating characteristics Increased activity of mammalian target of rapamycin(mTOR) protein is seen in neurofibromas. mTOR inhibitor rapamycin , or its derivatives such as everolimus may slow or stop tumor growth in patients with NF1.
Primary objectives To determine whether everolimus has an effect on the volume of surgically intractable and life-threatening internal plexiform neurofibromas in patients with neurofibromatosis 1.
Secondary objectives To determine whether everolimus has an effect on the number and the volume of cutaneous neurofibromas; to determine whether everolimus modify the signaling pathways in cutaneous neurofibromas.
- Adults with neurofibromatosis type 1 with at least one internal plexiform neurofibroma, life-threatening or causing significant morbidity through compression of organs. This or these internal plexiform neurofibroma(s) should be intractable by surgery.
An open-label, single arm, non-randomized, single stage phase IIa study. Baseline phase: Baseline evaluations will be performed within 2 weeks, and up to a maximum of 4 weeks for specific exams, before the first dose of study drug.
Treatment phase/duration of treatment: All patients will be treated with RAD001 10 mg p.o daily dose for one year except in case of unacceptable toxicity, death, or discontinuation from the study for any other reason.
Follow-up phase: All patients will have two follow-up visits scheduled at 18 and 24 months after the first dose of the study drug to follow for adverse events (AEs) and serious adverse events (SAEs) that may have occurred after discontinuation from the study and for internal plexiform neurofibromas assessment.
Radiological review: All Magnetic Resonance Imaging (MRIs) obtained at baseline, during the treatment period and the follow-up period will be reviewed by the Neuroradiologist of the study.
