Intestinal Microbiome Transplant in ALS

This 24-week study is looking at MTP-101C, a capsule made from healthy donor stool, for people with Amyotrophic Lateral Sclerosis (ALS). Researchers want to see if MTP-101C can help improve your daily function, measured by the ALS Functional Rating Scale, Revised (ALSFRS-R), and your quality of life (ALSAQ-5). They will also check for changes in a marker called Neurofilament Light Chain in your blood. You might be able to join if you are 18 or older, have a fast-progressing ALS diagnosis, and can swallow capsules. The study plans to enroll 20 participants.

Study design
This is a 24-week study where all 20 participants will receive the investigational product, MTP-101C. It is a Phase I/II study.
What's involved
You would have 4 in-person clinical visits and 4 phone visits over 24 weeks. You will also provide blood and stool samples, undergo antibiotic treatment, and a bowel preparation before taking MTP-101C capsules daily for 8 weeks.
Compensation
Not stated in the trial record.
Follow-up
Your ALSFRS-R and Neurofilament Light Chain levels will be measured at week 24, and your quality of life will be assessed at week 24.

Eligibility criteria

Inclusion

Diagnosis of ALS according to Gold Coast Criteria
Age: 18+ years at enrollment
Fast-progressing (ALSFRS-R change of at least 1.5 points per month between last 2 measurements at screening)
Modestly but not severely affected (ALSFRS-R score at or above 24 at screening)
Able to swallow capsules and expected to be able to for the duration of the trial (ALSFRS-R "swallowing" score of 3 or 4 at screening)
Expected to survive for the duration of the trial
Taking any combination of riluzole, edaravone, and/or tofersen at a stable dose for 30 days prior to screening, or not taking any of these and not expected to during the study.
Capable of giving written consent.
If sexually active, must agree to use contraceptive or abstinence for duration of treatment.
Females of child-bearing age must have negative pregnancy test at screening.

Exclusion

Concurrent illness or laboratory abnormalities that could confound the measurement of ALS progression or the microbiome or interfere with the ability to complete the study.
Taking probiotics, nutraceuticals, or herbal remedies within 2 weeks of screening
Taking antibiotics within 3 months of screening.
Taking any investigational study drug within 30 days of screening or five half-lives of the prior agent.
Previous exposure to MTT.
Pregnancy.
Known specific food allergy with anaphylaxis
Other co-morbid conditions that, in the opinion of the study investigator, place the participant at increased risk of complications, interfere with study participation or compliance, or confound study objectives.
  • ALS Functional Rating Scale, Revised (ALSFRS-R)Weeks 0, 4, 8, 12, 16, 20 and 24

    The ALSFRS-R is 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. The total score ranges from 0 to 48, where higher scores indicate better function.

  • ALS Quality of Life (ALSAQ-5)Weeks 0, 4, 12, and 24

    The overall ALSAQ-5 score ranges from 0 (best imaginable health state) to 100 (worst imaginable health state).

  • Neurofilament Light Chain levelsWeeks 0, 4, 12 and 24

    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.

  • The Gastrointestinal Symptom Rating Scale (GSRS)Weeks 0, 4, 12, and 24

    The Gastrointestinal Symptom Rating Scale (GSRS) is a 15-item questionnaire that can be used weekly to assess the severity of gastrointestinal symptoms experienced over the past week. The GSRS is designed to evaluate symptoms associated with common gastrointestinal disorders, such as reflux, abdominal pain, indigestion, diarrhea, and constipation. The questionnaire uses a seven-point Likert-type scale, with 1 representing no symptoms and 7 representing very troublesome symptoms. Higher scores on the subscales indicate more discomfort.
