Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 100 years
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: A total of 300 plexiform neurofibromas will be studied, consisting of 100 tumors in the head/neck and trunk/limbs (externally visible and internal)

Who may be able to join

  • Diagnosis of Neurofibromatosis: All study subjects will fulfill two or more of the diagnostic criteria listed below for NF1.
  • Six or more caf(SqrRoot)(Copyright)-au-lait macules
  • 1.5cm or larger in postpubertal individuals
  • 0.5 cm or larger in prepubertal individuals
  • Two or more neurofibromas of any type or 1 or more plexiform neurofibroma
  • Freckling in the axilla or groin
Show all 18Show fewer
  • Optic glioma (tumor of the optic pathway)
  • Two or more Lisch nodules (benign iris hamartomas)
  • A distinctive bony lesion
  • Dysplasia of the sphenoid bone
  • Dysplasia or thinning of long bone cortex
  • A first degree relative with NF-1
  • Plexiform Neurofibroma: A plexiform neurofibroma fulfilling entry criteria for the study will be defined as a diffuse soft tissue or nerve enlargement in a patient with NF1 that is causing, or has potential to cause, disfigurement or functional disability.
  • Distribution of Plexiform Neurofibromas by site: A total of 300 plexiform neurofibromas will be studied, consisting of 100 tumors in the following three groups (based on region of maximal involvement):
  • Head and Neck
  • Trunk and Limbs (externally visible)
  • Trunk and Limbs (internal) [spinal plexiform neurofibromas involve two or more levels with connection between the levels or extending laterally along the nerve]
  • Subject Ascertainment: Study subjects will be ascertained at any of the participating clinical centers. It is expected that these will include subjects already followed in these clinics, as well as newly diagnosed patients

Who cannot join

  • Presence of metallic implant(s) that will make the patient unable to have MRI studies
  • Presence of medical or psychological condition that will make the patient unable to tolerate MRI studies or anesthesia (if needed)
  • Inability to image tumor or define tumor margins by MRI (which may be determined after the initial study)
  • Failure to obtain initial MRI within 60 days of enrollment
  • Previous radiation therapy to site of plexiform neurofibroma
  • Surgery involving the plexiform neurofibroma (excluding biopsy) within a six month period before enrollment
  • Current antineoplastic therapy
  • Entry of more than one member of the same family into the study is not permitted

About this study

Official title: Natural History of Plexiform in Neurofibromatosis Type I

Background:

-Plexiform neurofibromas in patients with NF1 are a significant cause of morbidity but little is known about the natural history of these lesions.

Read more

Objectives:

  • The purpose of this study is to monitor the natural history of plexiform neurofibromas and to evaluate the usefulness of volumetric MRI tumor measurements in this disease.
  • Other goals of the study are to provide a body of normative data on the growth rate of plexiform neurofibromas and to establish a tissue repository and pathology review center to allow future studies of the pathogenesis of neurofibromas and clinical trials of potential therapeutic agents.

Design

  • This study is coordinated by Dr. Bruce Korf, and was initiated when he was at the Partners Center for Human Genetics, Boston, MA.

Questions about this trial

What is this clinical trial studying?

An observational study of Plexiform Neurofibromas and NF1, run by National Cancer Institute (NCI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Monitor natural history of plexiform neurofibromas (time frame: 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 May 2020.
