Brief 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

Condition or disease Intervention/treatment Phase
ALS (Amyotrophic Lateral Sclerosis) Drug: MNC (Mononuclear cells) Drug: Placebo / Saline Phase 2

Detailed 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.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: MNC (Mononuclear cells)

MNC (Mononuclear cells) (patients in which stem cells will be injected into the two muscles on one side and placebo -vehicle- in the two contralateral muscles).

This group would consist of 74 patients.

 Drug: MNC (Mononuclear cells)
  • Intramuscular infusion of autologous BM CMN into the TA muscle of one of the lower limbs (experimental side)
  • Intramuscular infusion of saline solution (placebo) in the TA muscle of the contralateral lower limb (control side)

Drug: Placebo / Saline
- Intramuscular infusion of saline solution (placebo) in the TA muscle of the contralateral lower limb (control side)
Placebo Comparator: Saline
(patients in which placebo -vehicle- will be injected into both muscles on both sides). This group would consist of 26 patients.
 Drug: Placebo / Saline
- Intramuscular infusion of saline solution (placebo) in the TA muscle of the contralateral lower limb (control side)


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Rate of serious and non-serious adverse events related to the use of bone marrow mononuclear cells in patients with Amyotrophic Lateral Sclerosis [ Time Frame: 48 months from baseline ]
  2. D50 index obtained from stimulus intensity curves [ Time Frame: 48 months from baseline ]
    This parameter quantifies the number and size of the functional motor units of a given muscle.


Secondary Outcome Measures :
  1. Motor unit number index" (MUNIX) [ Time Frame: 48 months from baseline ]
    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

  2. Motor unit size index" (MUSIX) [ Time Frame: 48 months from baseline ]
    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

  3. Fiber density (FD) [ Time Frame: 48 months from baseline ]
    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.

  4. PAMC amplitude: mV [ Time Frame: 48 months from baseline ]
    Compound muscle action potential (CMAP)

  5. PAMC area: mV / ms [ Time Frame: 48 months from baseline ]
    Compound muscle action potential (CMAP)

  6. Maximum force developed in an isometric contraction of the muscles [ Time Frame: 48 months from baseline ]
    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.

  7. Fuerza muscular (MRC Medical Research Council) score [ Time Frame: 48 months from baseline ]
    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.
