A Widely Inclusive, Hybrid-Decentralized Pilot Trial Utilizing β-hydroxy-β-methylbutyrate to Lower IGFBP7 Levels in People With ALS
2026年5月11日 更新者:Duke University
This is an open label trial of a supplement called HMB in patients with ALS.
The researchers are evaluating its safety and tolerability, as well as its ability to lower insulin-like growth-factor binding protein 7 (IGFBP7) and Neurofilament light chain levels (NFL) and to slow ALS Functional Rating Scale, Revised (ALSFRS-R) progression.
調査の概要
詳細な説明
This will be a widely inclusive, three-center, open-label pilot trial enrolling 100 people living with ALS.
Duke (25 participants) and Temple (25 participants) will be traditional sites that consent, screen and follow participants in person, Everything ALS (50 participants) will be a decentralized site providing virtual consenting, screening and follow up.
The total time commitment will be 9 months.
All participants who pass screening will provide demographics, disease characteristics, co-morbidities, and concomitant medications.
They will have a baseline ALSFRS-R score obtained, a baseline slope of Listener Effort Prediction Model (LEPM)-predicted Listener Effort (LE) progression, and Motor Movement Exam (MME) score.
For those who enroll at Duke or Temple, blood will be drawn for neurofilament light chain (NfL) and IGFBP7 levels.
For patients at Duke or Temple who consent to lumbar puncture, CSF will be drawn for NfL and IGFBP7 levels as well.
Each month after baseline, participants will be contacted by phone by each site's study coordinator to review adverse events, new co-morbidities, and concomitant medications, and to generate a new clinician-administered ALSFRS-R score.
For Duke and Temple participants, at month 1, 3 and 6 they will be asked to return for in person blood draws for NfL and IGFBP7 levels.
Those who sign the additional consent for lumbar punctures will have CSF drawn as well and this will be checked for NfL and IGFBP7 levels at month 3, too.
LSFRS-R is routinely measured as part of clinical care.
All of the described blood tests and investigational treatments are being performed exclusively for research purposes.
HMB will be given at a dose of 3g daily.

実験的:β-hydroxy-β-methylbutyrate (HMB) administration
|
Our source of HMB will be Life Extension's "Wellness Code Muscle Strength & Restore Formula.
The dose will be 3g daily, which has previously been shown to be safe and well-tolerated, and to reduce IGFBP7 blood levels in humans.

ALS Functional Rating Scale, Revised (ALSFRS-R)
時間枠:Baseline, month 3, month 9
|
A quickly administered (five minute) ordinal rating scale (ratings 0-4) used to determine patients' assessments of their capability and independence in 12 functional activities.
All 12 activities are relevant to people living with ALS.The ALSFRS-R declines linearly with time over a wide range during the course of ALS and it has been validated for telephone use.
The ALSFRS-R Range is 0-48.
The more points, the better the person is functioning.

Baseline, month 3, month 9

Speech (Listener Effort)
時間枠:Baseline, month 3, month 9
|
Listener effort (LE) is a perceptual rating of the amount of work necessary for a listener to understand speech, rated by an expert speech-language pathologist on a visual analog scale from 0 (easily understood) - 100 (unintelligible even with full effort) and it has proven to be one of the most robust overall measures of dysarthria.

Neurofilament Light Chain levels (blood)
時間枠:Baseline, month 3, and month 6
|
Neurofilaments are neuron-specific components of the cytoskeleton.
They exist in heavy, medium, and light chain forms.
Neurofilament light chain levels are elevated in the spinal fluid and the blood of patients with ALS and other neurodegenerative diseases, and higher levels predict more severe disease progression.
