|Official Title:||Conservative Iron Chelation as a Disease-modifying Strategy in Amyotrophic Lateral Sclerosis: Multicentre, Parallel-group, Placebo-controlled, Randomized Clinical Trial of Deferiprone|
|Actual Study Start Date :||January 1, 2019|
|Estimated Primary Completion Date :||November 2023|
|Estimated Study Completion Date :||November 2023|
Half of participants will receive twice-daily oral deferiprone taken over 12 months.
One 600 mg delayed-release tablets of deferiprone twice a day, for at 30 mg/kg/day
Other Name: DFP
Placebo Comparator: Placebo
Half of participants will receive the placebo Twice-daily oral placebo taken over 12 months
Drug: Placebo Oral Tablet
the placebo twice daily morning and evening.
- CAFS score (Combined Assessment of Function and Survival) [ Time Frame: at 12 months ]CAFS score based on changes in amyotrophic lateral sclerosis functional rating scale (ALSFRS-R) total scores and time to death from baseline (randomization visit) to 12 months
- Changes in ALS Functional Rating Scale-Revised (ALSFRS-R) total score [ Time Frame: Baseline, at 12 months ]
- All-cause and respiratory insufficiency mortality [ Time Frame: at 12 months ]Time to death for all cause or respiratory insufficiency (defined as tracheostomy or the use of non-invasive ventilation for ≥ 23 h per day for 14 consecutive days) from baseline until 12 month
- Changes in muscle strength [ Time Frame: Baseline, at 12 months ]Muscle strength measurements are determined by the overall mega-score for handheld dynamometry and manual muscular testing with a validated medical device provided
- Change in the slow vital capacity [ Time Frame: Baseline, at 12 months ]The slow vital capacity is measure by the maximum amount of air that can be exhaled following a deep breath. Reflecting the Respiratory insufficiency.
- Changes in body weight [ Time Frame: Baseline, at 12 months ]
- Change in Quality of life [ Time Frame: Baseline, at 12 months ]Quality of life assessed using the five-item form of the ALS assessment questionnaire (ALSAQ-5) from baseline to 12 months
- DSMIV criteria [ Time Frame: at 12 months ]Dementia (yes/no)
- Fronto-Temporal Dementia (FTD) criteria [ Time Frame: at 12 months ]Using the revised guidelines for the diagnosis of behavioral variant frontotemporal dementia based on recent literature and collective experience by Rascovsky K et al 2011; Lamarre AK et al 2013
- Change in Montreal Cognitive Assessment (MoCA) [ Time Frame: Baseline, at 12 months ]MoCA evaluated of mild cognitive dysfunction.
- Change in Edinburgh Cognitive and Behavioural Amyotrophic Lateral Sclerosis Screen (ECAS) [ Time Frame: Baseline, at 12 months ]
ECAS determine cognitive and behavioral changes of patients suffering from Amyotrophic Lateral Sclerosis.
With ECAS, ALS-specific (fluency, executive functions and social cognition, language) and ALS-nonspecific (memory, visuospatial functions) functions can be analyzed to enable the distinction from other diseases with cognitive and behavioral impairments.

|Ages Eligible for Study:||18 Years to 75 Years (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Categorized as; possible, laboratory supported probable, probable, or definite ALS (revised El Escorial criteria)
- Spinal and bulbar forms of ALS
- Duration of the disease of less than 18 months since the first symptoms of motor deficit or amyotrophy (isolated cramps or fasciculation will not be considered).
- Duration of the disease of less than 6 months since the diagnosis
- An upright slow vital capacity ≥ 75% of the predicted value for age, height, and sex or at least one test on inspiratory pressure ≥ 60% of the predicted value for age, height, and sex which could be either maximal inspiratory pressure or a SNIFF test. (The best predictive test is sniff test but sometime patients are not able to do it.) (In case of a limit abnormal value for one of them, it will be recommended that patient re-assessment occurs three months later).
- A mild functional handicap score for ALSFRS-R ≥36
- An upright slow vital capacity > 70% of the predicted value for age, height, and sex and
- Able to swallow (required for oral treatment)
- Patients weight included between 40 kg and 130 kg
- If the patient is under riluzole, it has to be for at least 1 month before inclusion with stable dose (to rule out the principal risk of hepatitis)
- Patients with high frequency of comorbidity or vital risks that may reasonably impair life expectancy
- Progressing axis I psychiatric disorders (psychosis, hallucinations, substance addiction, bipolar disorder, severe depression, suicidal ideation), in accordance with the Diagnostic and Statistical Manual of Mental Disorders. Before entry into the study, exclusion or stabilization of conditions must occur for patients suffering from mild or moderate depressive episodes (not in remission) or severe and uncontrolled anxiety.
- Dementia according to the Diagnostic and Statistical Manual of Mental Disorders
- Exposure to any other experimental drug up to 30 days before day 1
- Due to the risk of agranulocytosis (estimated at 2%) caused by the Investigational Medicinal Products (IMPs) and the unknown mechanism by which this agranulocytosis is induced, combining Deferiprone with other medicinal products known to cause agranulocytosis (as described in the IB) will not be allowed. Such medicinal products include clozapine as well as some NSAIDs (e.g. Phenylbutazone or Metamizole), antithyroid agents, sulfonamide antibiotics or methotrexate.
- A history of relapsing neutropenia
- Patients with agranulocytosis or with a history of agranulocytosis.
- Hypersensitivity to Deferiprone
- Patients with anaemia (regardless of latter aetiology) or a history of another haematological disease. Haemochromatosis is not an exclusion criterion if controlled.
- Pregnant or breastfeeding women or women of childbearing potential not taking highly effective contraception.
- Kidney or liver failure.
- Inability to provide informed consent.
- Participation in another clinical trial within 1 month prior to inclusion in the study
- Patients under trusteeship
