Study Description

Brief Summary:

The purpose of this pilot study is to assess the safety and tolerability of multiple doses of MaaT033 in ALS patients and to analyze the gut microbiota composition and evolution before considering a larger randomized controlled efficacy study.

Condition or disease	Intervention/treatment	Phase
Amyotrophic Lateral Sclerosis; ALS	Drug: MaaT033	Phase 1

Detailed Description:

This is a prospective, single arm, open-label study.

The target population includes subjects with a recent disease onset defined as the time from first motor deficit at screening of at least 6 months and up to 24 months and removing very rapid/slow progressors based on the ALS Functional Rating Scale - Revised (ALSFRS-R) progression slope.

After a screening period (clinical examination, blood sampling), subject will come for a baseline visit (clinical examination, blood and feces sampling) and to initiate a bowel preparation phase. Five days later, subject will come back to the study site (clinical examination, blood sampling) to initiate a first Maat033 treatment period of 28-day. Ten days after MaaT033 treatment initiation a remote visit is included (feces sampling) to check the subject safety/tolerability. After the first Maat033 treatment period, subject will come to the study site (clinical examination, blood and feces sampling) to initiate the second MaaT033 treatment period of 28-day. At the end of the second Maat033 treatment period subjects will come to the study site (clinical examination, blood and feces sampling) and start a 28-day follow-up period without treatment.

Study completion is defined when all subjects enrolled completed the study follow-up period (clinical examination, blood and feces sampling) or earlier if a subject discontinued the study.

Arms and Interventions

Arm	Intervention/treatment
Experimental: MaaT033; Route of administration: oral (capsule) Between D-5 to D-1: Bowel preparation with Macrogol and Rifamixin Between D1 to D28: MaaT033 treatment period 1 Between D28 to D56: MaaT033 treatment period 2	Drug: MaaT033; MaaT033 is a Microbiome Ecosystem Therapy (MET), composed of allogeneic, full-ecosystem pooled biotherapeutic gut microbiota.

Outcome Measures

Primary Outcome Measures :

1. Safety and tolerability: Incidence of Treatment Emergent Adverse Events (TEAE) grade >3, according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 [ Time Frame: Day 84 ]
   To assess the safety and tolerability of MaaT033 treatment

Secondary Outcome Measures :

1. Changes in gut microbiota profile [ Time Frame: From Day -5 to Day 84 (at Day -5, Day 10, Day 28, Day 56 and Day 84) ]
   Analysis of fecal samples to assess gut microbiota alpha- and beta-diversity indices
2. Changes in levels of biomarkers in blood [ Time Frame: From Day -5 to Day 84 ]
   • Changes from baseline (Day -5) of neutrophil/ lymphocyte ratio, Interleukins (IL): IL-2, IL-6 and IL-8, Interferon gamma (IFNg), Tumor Necrosis Factor alpha (TNFa), Monocyte Chemoattractant Protein-1 (MCP-1), Transforming Growth Factor-beta (TGFb), the soluble subtype of CD14 (sCD14), C-reactive protein (CRP), erythrocyte sedimentation rate, plasma soluble Lipopolysaccharide Binding Protein (LBP), creatinin and serum Short-Chain Fatty Acids (SCFA) at Day 28, Day 56 and Day 84.
   • Changes from baseline (Day -5) of serum Neurofilament light (NfL) at Day 56 and Day 84.
3. Changes in levels of fecal calprotectin [ Time Frame: From Day -5 to Day 84 ]
   Changes from baseline (Day -5) of fecal calprotectin at Day 10, Day 28, Day 56 and Day 84
