Clinical Trial Summary

Our working hypothesis is that the injection of autologous bone marrow mononuclear cells (BMNC) has a positive effect on the natural loss of motor units and on the increase in the size of the motor unit that occurs in patients with ALS during the evolution of the disease

Description:

Our working hypothesis is that the injection of autologous bone marrow mononuclear cells (BMNC) has a positive effect on the natural loss of motor units and on the increase in the size of the motor unit that occurs in patients with ALS during the evolution of the disease.

This hypothesis is based on experimental work done in animal models of ALS and the results of our previous phase I clinical trial. In this clinical trial (TCIM / ALS, ClinicalTrials.gov Identifier: NCT02286011) we studied with electrophysiological techniques (in a small number of patients with ALS) the effects of intramuscular injection of a single dose of BMSC in the tibialis anterioris (TA) muscle. . The results indicate that this is a safe procedure and show the presence of a positive and apparently transitory effect on the size and number of motor units of the TA muscle.

Eligibility

Inclusion Criteria:

• Diagnosis of ALS defined or probable according to the criteria established by the World Federation of Neurology

• Age between 18 and 70 years.

• Patient who offers sufficient guarantees of adherence to the protocol.

• Neurophysiological data confirming lower motor neuron involvement at the lumbar and cervical level.

Exclusion Criteria:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of serious and non-serious adverse events related to the use of bone marrow mononuclear cells in patients with Amyotrophic Lateral Sclerosis		48 months from baseline
Primary	D50 index obtained from stimulus intensity curves	This parameter quantifies the number and size of the functional motor units of a given muscle.	48 months from baseline
Secondary	Motor unit number index" (MUNIX)	The unit amplitude (or area) of the individual motor units are calculated from the amplitude variations (or area) of the muscle action potential obtained in response to stimuli from a fixed intensity	48 months from baseline
Secondary	Motor unit size index" (MUSIX)	The unit amplitude (or area) of the individual motor units are calculated from the amplitude variations (or area) of the muscle action potential obtained in response to stimuli from a fixed intensity	48 months from baseline
Secondary	Fiber density (FD)	Quantifies the average number of muscle fibers per motor unit. It is obtained from single fiber recordings made with electrodes. The average number of motor unit potentials is calculated in 20 different positions in the muscle.	48 months from baseline
Secondary	PAMC amplitude: mV	Compound muscle action potential (CMAP)	48 months from baseline
Secondary	PAMC area: mV / ms	Compound muscle action potential (CMAP)	48 months from baseline
Secondary	Maximum force developed in an isometric contraction of the muscles	The measurement will be made with a dynamometer during dorsiflexion of the foot (from certain angles) and during abduction of the index finger of the hand, respectively.	48 months from baseline
Secondary	Fuerza muscular (MRC Medical Research Council) score	Muscle strength data will be collected according to the Medical Research Council scale. Muscle strength is graded on a scale of 0 to 5, with 5 being normal muscle strength and 0 being the absence of muscle contraction.	48 months from baseline
