A Decentralized Clinical Trial to Promote Evidence-Based Care for Underserved Patients With Neurofibromatosis 1

September 30, 2025 updated by: Vanessa Merker, PhD, Massachusetts General Hospital

The goal of this fully decentralized, randomized controlled trial is to compare the efficacy of two educational interventions for individuals with Neurofibromatosis 1 (NF1). The primary objective of the study is to determine which intervention leads to higher rates of evidenced-based health screenings for NF1 patients in primary care settings.

Adults with NF1 and parents/guardians of children with NF1 from across the U.S. who do not go to a specialized NF clinic and who have an upcoming annual wellness visits (e.g. an annual physical, a well-child visit, etc.) scheduled with a primary care provider (PCP) are eligible to enroll in the study.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background: The majority of individuals with Neurofibromatosis 1 (NF1) in the United States lack access to specialized NF1 clinics and consequently don't receive care aligned with national recommendations. To address this gap in care, researchers are evaluating two interventions to determine which one helps people get recommended NF1-related health screenings at their annual wellness visit with a primary care provider.

Methods: Participants (adult patients or parents) who enroll in the study will complete baseline survey assessments online before their PCP visit and then be randomized to one of two groups. Both groups will be given letters, one for themselves and one for their clinician, that describe NF1 care recommendations. After attending their annual wellness visit, all participants will be asked to complete an online follow-up survey. A small subsample of participants will also be asked to do a virtual qualitative interview. No visits to Massachusetts General Hospital are required for this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Receipt of Recommended NF1 Health Screenings
Time Frame: 2 weeks after PCP visit
Number of AAP and ACMG recommended health screenings received by the person with NF1 at the annual wellness visit with their PCP, as assessed by patient/parent self-report
2 weeks after PCP visit

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient Activation Measure®
Time Frame: At baseline and 2 weeks after PCP visit
The Patient Activation Measure will be used to assess patient's and parent's self-efficacy managing their or their child's care. The patient form has 13 items and the parent form has 10 items. The measure has scores ranging from 0-100, where higher scores indicate higher patient/parent activation (e.g. self-efficacy in managing your own or your child's healthcare).
At baseline and 2 weeks after PCP visit
Consumer Assessment of Healthcare Providers and Systems (CAHPS®) Clinician and Group Survey Version 4.0 (Beta): Rating of the Visit
Time Frame: 2 weeks after PCP visit
The CAHPS® Rating of the Visit will be used to assess patient/parent satisfaction with the visit. This rating is a single item scored from 0 to 10, where higher scores indicated a better visit.
2 weeks after PCP visit
Consumer Assessment of Healthcare Providers and Systems (CAHPS®) Clinician and Group Survey Version 4.0 (Beta): How Well Providers Communicate With Patients Subscale
Time Frame: 2 weeks after PCP visit
The subscale will be used to assess How Well Providers Communicate With Patients. This scale will be scored from 0 to 100, where higher scores indicated better communication with patients.
2 weeks after PCP visit
Consumer Assessment of Healthcare Providers and Systems (CAHPS®) Clinician and Group Survey Version 4.0 (Beta): Providers' Use of Information to Coordinate Patient Care Subscale
Time Frame: 2 weeks after PCP visit
The subscale will be used to assess Providers' Use of Information to Coordinate Patient Care. This scale will be scored from 0 to 100, where higher scores indicate better use of information to coordinate care.
2 weeks after PCP visit
