Detailed Description
Amyotrophic lateral sclerosis (ALS) is a rare but fatal condition of the motor neuron. Despite intense therapeutic research in recent years, riluzole remains the only drug with proven efficacy in patients with this disease. In 2008 an Italian clinical-basic study reported benefits with lithium carbonate in both the experimental model of ALS and in a small sample of patients. In the same year, two Chinese studies showed a synergistic neuroprotective effect of valproate administered with lithium in neuronal cultures and in G93A ALS transgenic models.
A clinical trial with lithium carbonate and magnesium valproate,conducted from 2009 to 2012 in 18 patients with diagnostic criteria of ALS compared to a sample of 31 contemporary patients who did not receive the drug showed functionnal stability and an increase in antioxidant defenses in subjects under double treatment. Despite the low level of evidence from this open study, the combination of clinical and biological results as well as the significant increase in survival of treated subjects invites us to conduct a study yielding harsh results on the efficacy of dual treatment.
To obtain harder data, the study will include 40 subjects with random assignation of the treatments (active vs. placebo) by electronic means. The development of the placebo tablets will be in charge of two pharmaceutical companies. Their delivery and purchase will be performed by a nursing team, the same team that will store and conserve the treatments. The preparation and packaging of the tablets for two months for 10 patients will be done regularly in a sterile environment. Two computer engineers will be in charge of the elaboration of the labels and the numerical draw of the treatments. The coordinator of the study will request the treatments in the nursing warehouse equipped with humidity and temperature control. Another person will be trained to make contacts, home deliveries, bottle changes and tablet counts. The appointments will be scheduled by the researchers every 2 months as well as biosecurity exams and magnetic resonance studies in each patient within a 20-month interval.
This pilot study will allow the treatment efficacy to calculate the sample size required for the national and international multicenter clinical trial if relevant, to be promoted at the Mexican Academy of Neurology. It will also allow the study of the behavior of blood and MRI biomarkers ( SOD activity , DTI in cortico-spinal tract, and morphometric indexes).
