A Multicenter Phase I/II Clinical Trial to Evaluate Safety of Mesenchymal Stem Cell in Patients With Amyotrophic Sclerosis Lateral

A Multicenter Phase I/II Clinical Trial, Randomized, Controlled With Placebo, Triple Blind to Evaluate Safety, and Indications of Efficiency of the Intravenous Administration of the Therapy With 3 Doses of MSC in Patients With ASL Moderated to Severe

A multicenter phase I/II Clinical trial,randomized, controlled with placebo, triple blind to evaluate the safety of the intravenous administration of 3 doses of autologous mesenchymal stem cells cells from adipose tissue in patients with Amyotrophic Lateral Sclerosis (ALS).

A multicenter phase I/II Clinical trial,randomized, controlled with placebo, triple blind to evaluate the safety of the intravenous administration of 3 doses of autologous mesenchymal stem cells cells from adipose tissue in patients with Amyotrophic Lateral Sclerosis (ALS).

40 patients will be enrolled and will be randomized into one of the following 4 arms:

• 10 patients in the control group (placebo)
• 10 patients received a dose of 1 million MSC / kg
• 10 patients received a dose of 2 million MSC / kg.
• 10 patients received a dose of 4 million MSC / kg

The follow-up phase of each patient from the cell infusion/placebo will be 6 months.

At the time that each patient completed the follow-up period (i.e., 6 months after the infusion of the cellular product or placebo), the blind will be open, and patients who have been assigned to the control group, will receive the cell product as secondary treatment. These patients will be randomized to receive each of the doses used in the first phase. From this point, they begin a second period of follow up of 6 months.

In addition, after 6 months of MSC infusion, every patient will continue in an open extension study for 36 months to assess the safety of MSC.

Inclusion Criteria:

1. Women and males over 18-year-old.
2. Good understanding of the protocol and aptitude to grant the informed assent.

5. More than 6 and less than 36 months of evolution of the disease (from the beginning of the symptoms).
6. Possibility of obtaining, at least, 50gr of adipose tissue.
7. Treatment with riluzole, for at least, a month before the inclusion.

Exclusion Criteria:

2. Previous therapy with stem cells.
3. Participation in another clinical trial during 3 months previous to the entry in this trial.
4. Any disease lymphoproliferative
5. Tracheostomy and /or gastrostomy.
