Neurofibromatosis Type 1 Tumor Early Detection Study
(NF1-TED)
What this study is about
The goal of this observational study is to determine if a liquid biopsy (i.e. blood test) is an effective clinical tool for monitoring the development of malignant peripheral nerve sheath tumor (MPNST) among adults (18 years and older) with Neurofibromatosis Type 1 (NF1), compared to the current the usual treatment.
View original scientific description
The goal of this observational study is to determine if a liquid biopsy (i.e. blood test) is an effective clinical tool for monitoring the development of malignant peripheral nerve sheath tumor (MPNST) among adults (18 years and older) with Neurofibromatosis Type 1 (NF1), compared to the current standard of care. The main questions it aims to answer are: How effective is liquid biopsy compared to the current standard of care (clinical surveillance and imaging) for early detection of MPNST development among people with NF1? Can liquid biopsy offer a cost-effective method for early detection of MPNST in people with NF1? Also, can liquid biopsy provide earlier detection that potentially leads to better outcomes? Also, can offering liquid biopsy improve access to care for people experiencing barriers to access (such as minority populations or people in rural areas)? At baseline, participants will be asked to: * Complete surveys to provide their demographic and NF1-related health information. * Report whether or not they are experiencing MPNST-related symptoms. * Provide blood samples (15 mL blood total between three tubes, which is approximately one tablespoon). Every six months during the five-year follow-up period, participants will be asked to: * Complete additional surveys to report whether or not they are experiencing MPNST-related symptoms and/or if they have been diagnosed with a new MPNST. * Provide an additional blood sample (10 mL blood total in one tube). If diagnosed with an MPNST by their healthcare provider during the follow-up period, participants will be asked to: * Complete an additional survey regarding their diagnosis and symptoms. * Provide an additional blood sample (10 mL blood in one tube). * In parallel, the study team will request a sample of tumor tissue from the care provider, if available.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
