Summary
Prospective, international, randomised, double-blind, placebo controlled, multicentre, parallel group study. Patients will be randomised in a 2:1 allocation ratio to receive either IFB-088 + riluzole 100 mg or placebo + riluzole 100 mg. This clinical trial is an exploratory study, designed to show a signal of efficacy of IFB-088 through ALSFRS-R, MITOS and King's College. Respiratory function will be followed through SVC. Biomarkers and quality of life will also be evaluated throughout the study.
Patients will be treated over a 6-month period. After a screening/consent visit, patients will undergo clinic visits at randomisation (V0), at 2 weeks (V1), and at months 1 (V2), 3 (V3) and 6 (V4). One week after V0, the patient will undergo urine analysis (dipstick)and blood sampling for measurement of creatinine
, as well as blood sampling for measurement of creatinine and calculation of eGFR at months 2, 4 and 5. At the V2 visit, in addition to other assessments, patients will undergo blood sampling for PK measurements and urine sampling for crystalluria examination. Blood and urine chemistry, as well as physical examination and vital signs assessment to assess safety will be performed at each visit for safety purpose and crystalluria examination will be repeated at the follow-up visit, performed one month ± one week after V4.

Exclusion Criteria
- Known other significant neurological disease(s),
- Serious illness(es) or medical condition(s) (e.g. unstable cardiac disease, cancer, hematologic disease, hepatitis or liver failure, renal failure) that is not stabilised or that could require hospitalisation and may jeopardise the participation in the study,
