Clinical Trial Readiness to Solve Barriers to Drug Development in FSHD (ReSolve)

April 7, 2026 updated by: University of Kansas Medical Center
The primary cause of facioscapulohumeral muscular dystrophy (FSHD), a common adult-onset dystrophy, was recently discovered identifying targets for therapy. As multiple drug companies pursue treatments for FSHD, there is an urgent need to define the clinical trial strategies which will hasten drug development, including creating disease-relevant outcome measures and optimizing inclusion criteria. This proposal will develop two new outcome measures (FSHD-COM and EIM) and optimize eligibility criteria by testing 320 patients across 14 international sites over a period of 24 months.

Study Overview

Detailed Description

The overall aim of this study is to hasten drug development for facioscapulohumeral muscular dystrophy (FSHD). Recent breakthroughs in FSHD research have identified the primary disease mechanism as the aberrant expression of a normally silenced gene, DUX4, resulting in a toxic gain-of-function. This disease mechanism is particularly amenable to knock-down of DUX4 using epigenetic strategies or RNA therapies, as well as to other interventions targeting the downstream effects of DUX4 expression. There are many drug companies actively working towards disease-targeted therapies, and two clinical trials either under way now, or planned to start in early Fall 2016. However, meetings with industry, advocacy groups, and FSHD researchers have identified several gaps in the clinical trial arsenal, and clinical trial planning as a major goal for the community. Consequently, there is an urgent need to establish the tools necessary for the conduct of currently planned and expected therapeutic trials in FSHD.

To this end, the researchers propose to develop two novel clinical outcome assessments (COA), a composite functional outcome measure (FSHD-COM) and skeletal muscle biomarker, electrical impedance myography (EIM). In addition, there is broad consensus a better understanding of the relationship of genetic and demographic features to disease progression will be necessary for enumerating eligibility criteria.

The specific aims are to: 1. Determine the multi-site validity of the COAs, 2. Compare the responsiveness of new COAs to other FSHD outcomes and determine the minimal clinically meaningful changes, and 3. establish FSHD cohort characteristics useful for determining clinical trial eligibility criteria. To achieve these aims, the researchers are conducting a multicenter, prospective, 24 months study of 320 subjects.

FSHD-COM
All participants will be asked to undergo FSHD-specific functional rating scale tests and procedures and Electrical Impedance Myography.
The FSHD-COM is composed of disease-relevant functional tasks such as leg function; shoulder and arm function; trunk function, hand function, and balance.
Other Names:
  • FSHD-COM
EIM is a non-invasive, painless, and fast technique for obtaining information on how a patient's muscle structure is changing. EIM uses a small electrical current to measure the health of the underlying muscle. The patient will be asked to lie down and a trained clinical evaluator will perform testing on 16 total muscles (8 on each side) on your arms and legs.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
FSHD composite (FSHD-COM)
Time Frame: 24 Months
The FSHD composite (FSHD-COM) is an 18-item evaluator-administered instrument comprised of individually validated functional motor tasks. The body regions represented match areas of importance identified by patients and include: leg function; shoulder and arm function; trunk function, hand function; and balance. Each item is scored on a 0-4 scale, with 0 representing unaffected/normal performance, and the divisions based on healthy population normative values, or the relative degree of ability to perform the functional task. The total scale has 72 points, with larger weight given to the two most frequently patient-cited areas of functional motor concern - leg function and shoulder and arm function.
24 Months
Electrical Impedance Myography (EIM)
Time Frame: 24 Months
EIM is administered using an investigational device manufactured by Skulpt, Inc (Boston, MA) that non-invasively measures the impedance of skeletal muscle over a frequency range between 1 kHz and 10 MHz (Figure 2). The impedance is measured at each frequency by applying low-intensity electrical current (<1 mA) via surface electrodes and measuring the resulting voltage signals using a second set of surface electrodes, converting them into 2 impedance parameters, the resistance and the reactance.
24 Months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Motor Function Measure (MFM) Domain 1
Time Frame: 24 Months
The MFM domain 1 is a validated evaluator administered functional measure for neuromuscular disorders, with 13 items related to standing and transfers.
24 Months
Facial Function
Time Frame: 24 Months
The Iowa Oral Performance Instrument (IOPI) is a means to quantify lip, tongue, and buccal strength using a validated tool with published ranges for normative data for lingual measurements.
24 Months
Whole body and regional lean muscle mass (LMM)
Time Frame: 24 Months
Whole body and regional lean muscle mass (LMM) will be measured via Dual Energy X-Ray Absorptiometry (DEXA).
24 Months
Severity Scores
Time Frame: 24 Months
A limited physical exam and strength testing will be used to derive two FSHD clinical severity scores. These severity scores both rank weakness in the face, shoulders, arms, distal, and proximal lower extremities on either a 10 or 15 point scale.
24 Months
FSHD-Health Inventory (HI)
Time Frame: 24 Months
The HI is a 15 domain questionnaire designed and based on patient interviews to measure total FSHD health-related quality-of-life, including both motor impairment and the social and emotional impact of FSHD. 116 questions are combined into a total score, the score is transformed onto a percentage scale, with 100 representing maximal disability, and lower scores representing decreasing disability.
24 Months
Patient-Reported Outcomes Measurement Information System-57 (PROMIS57)
Time Frame: 24 Months
The PROMIS57 is an instrument developed by the NIH which generates scores for physical function, and the impact of physical limitations on daily life. 57 questions are summed into a total score, which is transformed into a normalized t-score with 50 representing normal, and lower scores representing increasing disability.
24 Months
The Upper Extremity Functional Index
Time Frame: 24 Months
This index measures upper extremity dysfunction. 20 questions are combined into a total score, the score is transformed into a normalized score with 80 representing normal, and lower scores representing increasing disability.
24 Months
The Facial Disability Index (FDI)
Time Frame: 24 Months
The FDI is a short 5 item questionnaire. The five questions are summed into total score which transformed onto a percentage scale, with 100 representing normal, and lower scores representing increasing disability.
24 Months
Fall assessment
Time Frame: Total between Month 3 and Month 6 Visit
Fall assessment will be completed weekly for 3 months after the month 3 visit.

24 Months
Domain Delta Anchor
Time Frame: 24 Months
Participants will be asked to complete a self-assessment "domain-delta" questionnaire at 3, 12, 18 and 24-month visits. The purpose of the "domain-delta" questionnaire is to determine each patient's perceived change in their health-related quality-of-life in the last 6-months. This questionnaire will inquire about total health as well as health related to 14 subdomains self-identified as important by patients during development of the FSHD Health Index. Participants indicate their perceived change by answering if an area "is a lot worse", "is a little worse", "there has been no change", "it is a little better", or "it is a lot better" for each subdomain.

Participants will undergo one needle muscle biopsy of one lower extremity muscle (Vastus Lateralis (VL), Tibialis Anterior (TA), Medial Gastrocnemius (MG), or Lateral Gastrocnemius (LG)) at any study visit. For each biopsy, approximately three muscle tissue samples will be collected, two samples will be individually flash frozen in liquid nitrogen while the third sample will be put into media for myoblast cell cultures.
