Acetylcholine Receptors From Human Muscles as Pharmacological Target for

Status Completed

Clinical Trial Summary

Amyotrophic lateral sclerosis (ALS) is a fatal disease leading to motor neuron degeneration and progressive paralysis. Other studies have revealed defects in skeletal muscle even in absence of motor neuron anomalies, focusing on acetylcholine receptors (AChRs) and supporting the so-called "dying-back" hypothesis. Outcome of this study will be to understand if the endocannabinoid palmitoylethanolamide (PEA) can reduce the rundown of AChRs currents in ALS muscle, and if it can modify ALS patients' clinical and electrophysiological parameters.

Clinical Trial Description

Outcome:

Monitoring the efficacy and safety of PEA in the treatment of patients with ALS. Analysis of AChR currents and description of the composition of AChRs subunits in ALS muscles

Design of the Study:

A randomized controlled blinded study. Patients with sporadic ALS will receive riluzole alone or riluzole+PEA in order to investigate the clinical and electrophysiological effects of treatment. The expected number of enrolled patients will be 50.

All patients satisfying the selection criteria will be randomized into two groups: a first group will be treated only with riluzole, the second group with riluzole associated with PEA (Normast 600 mg microgranular, 2 sachets/day). The randomization will be done stratifying patietns according to type of clinical onset (bulbar vs. spinal). The patients will be enrolled in the Department of Neurology and Psychiatry, University of Rome "Sapienza".

The visits will be performed at 0 (randomization), 3 and 6 months. At each visit the ALS Functional Rating Scale-Revised (ALSFRS-R), the percentage of predicted forced vital capacity (FVC%), the Medical Research Council (MRC) score for muscle strength limited to the right upper limbs, and the compound muscle action potentials (CMAP) from right ulnar and phrenic nerves will be assessed. A muscle biopsy will be done at the end of the study. The obtained results will be compared with those observed in muscle samples from denervated (non-ALS) control patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
