Natural History Study of Patients With VCP-related Disease

Active, not recruiting

• Conditions: IBMPFD

• Registration Number: NCT04823143
• Lead Sponsor: Nationwide Children's Hospital

Brief Summary

A natural history study to understand the expected progression of disease in patients with confirmed mutations in the VCP gene over 1 year.

Detailed Description

This is a single site, prospective natural history study to evaluate the utility of strength, functional, and patient reported outcomes in quantifying disease progression over 1 year in patients with mutations in the VCP gene.

Patients will complete a remote and onsite visits at baseline, a remote visit at 6 months, and then a final remote and onsite visit at 12 months. All strength, functional, and patient reported measures will be completed at each visit to assess reliability, consistency of results across testing environments, and sensitivity to change over time.

Additionally, patients may opt in to provide blood, serum, and urine samples for biobanking.

Primary Outcome Measures

Name	Time	Method
9 hole peg test	12 months	Records the time it takes a patient to place 9 pegs in holes and remove as quickly as possible
Forced Vital Capacity	12 months	Records the maximum volume a patient can expire forcefully from their lungs in the seated position.
North Star assessment for limb girdle type dystrophies (NSAD)	12 months	A 29-item assessment of functional tasks such as standing, walking, rising from floor, standing on 1 leg, etc. This assessment also includes 2 timed items: rise from floor and 10 meter walk/run. Each task is scored on a 0=unable, 1=completed with compensation, 2=completed without compensation. A total score for all items is recorded.
Timed Up and Go	12 months	A patient stands from a chair, walks 3 meters, and returns to sitting in the chair as quickly as possible. The time to complete is recorded.
4 stair climb	12 months	Records the fastest time a patient can ascend 4 steps using handrails as needed.
Performance of Upper Limb (PUL) 2.0	12 months	A 22-item assessment of upper extremity tasks such as lifting arms overhead, bringing a cup to mouth, tearing paper, stacking cans, etc. Each task is scored on a 0=unable, 1=completed with compensation, 2=completed without compensation. A total score for all items is recorded.
PROMIS Global Health scale	12 months	10 item patient reported measure with questions about a patient's rating of overall health, quality of life, and ability to complete and participate in regular activities.
Neuro-QOL Upper Extremity Function	12 months	A patient reported outcome with questions about a person's ability to complete activities of daily living including bathing, dressing, turning a key in a lock, etc
100 meter timed test	12 months	Patients will complete 100-meter walk/run on a 25-meter course as quickly as possible, safely. The time to complete is recorded.
EAT-10	12 months	A 10-item patient-reported assessment with questions related to swallowing function.
Neuro-QOL Lower Extremity Function (Mobility)	12 months	A patient reported outcome with questions about a person's ability to complete mobility activities such as stepping up on curbs, transfers, pushing open doors, etc
Speech Handicap Index	12 months	This patient-reported measure includes questions related to speech functions and abilities.
Rasch Overall ALS Disability Scale (ROADS)	12 months	A 28-item patient reported measure with questions about swallowing, speaking, mobility, and upper extremity tasks.
Neuro-QOL Cognition Function	12 months.	A patient reported outcome with questions about a person's regular cognitive ability including reading, thinking, paying attention, and concentrating.
Communicative Participation Item Bank (CPIB)	12 months	A self-reported measure with questions related to ability to communicate, be understood, and relative difficulty or ease in communicating.
