Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this trial is to study the effect of Memantine (uncompetitive, moderate affinity, NMDA receptor antagonist that binds to the NMDA receptor channel, and regulates the calcium influx into the neurons), a drug used to treat Alzheimer´s disease, on the progression of Amyotrophic Lateral Sclerosis (ALS). Memantine is added to riluzole (the single drug approved to treat ALS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Phase 2/3 trial in ALS patients Double-blinded, parallel, randomized (2 blocs, bulbar/spinal onset)

Memantine + riluzole x Placebo + Memantine

Inclusion criteria:

* \< 75 years at disease onset
* \< 3 years of disease progression
* ALS-FRS \> 24
* FVC \> 60
* Probable or definite disease (revised El Escorial criteria)
* No other medical condition
* Normal blood tests
* Regular medication on riluzole \> 1 month
* Nerve conduction studies ruling out conduction block
* EMG with widespread loss of motor units (revised El Escorial criteria)
* At least one hand with ADM strength \> 2 on MRC scale

Duration - 2 years

Evaluation - every 3 months

Primary outcome - ALS-FRS Secondary -SF36, Hamilton depression scale, motor unit number estimation, neurophysiological index, strength (clinical evaluation); side-effects

Intention to treat analysis

60 patients

number estimated for 50% change in decline rate of ALS-FRS
