The Evaluation of the Effect of Mesenchymal Stem Cells on the Immune System of Patients With ALS

The Evaluation of the Effect of Wharton's Jelly Mesenchymal Stem Cells (WJMSCs) on the Immune System of Patients With Amyotrophic Lateral Sclerosis (ALS)

The objective of this study is to evaluate the safety of intrathecal administration of Wharton's Jelly Mesenchymal Stem Cells (WJMSC) and the impact on the immune system of patients with Amyotrophic Lateral Sclerosis.

Clinical Phase: I/II

Population: Patients with Amyotrophic Lateral Sclerosis.

Project Design: One arm, non-blinded, open label study

Planned Sample Size: 20 patients

Investigational Medicinal Product: active IMP - mesenchymal stem cells isolated from Wharton's jelly

Screening:

Three visits on site to check the eligibility criteria (around 90, 60 and 30 days before first IMP administration)

Treatment (IMP administration):

Each patient will receive IMP three times: on baseline (day 0), 30 and 60 days after baseline (+/- 7 days).

Administration route: intrathecal

Follow up:

Duration: 18 months after first IMP administration Four on-site visits (3, 6, 9, 12 months after first IMP administration) and seven phone visits (4, 5, 7, 8, 10, 11 and 18 months after first IMP administration)

Inclusion Criteria:

1. Adult patients (at least 18 years old)
2. The minimum patient's weight is not less than 40 kg
3. Diagnosis of sporadic ALS, definite or probable, as defined by El Escorial World Federation of Neurology criteria
4. History of ALS symptoms less than 2 years duration from the first symptoms of the disease
5. More than 6 months from diagnosis of the disease
6. Disease progression at 6 past months at least 3 points during this period of time assessed in ALSFRS-R scale
7. ALSFRS-R scale of at least 30 at screening appointment
8. Forced vital capacity >70% of predicted value for age, gender and height
9. Treatment with stable dose of riluzole(2x 50mg per 24h) before baseline visit (for at least 1 month)
10. Capable of providing written informed consent
11. Able to comply with study requirements and willing to follow all study procedures and follow-up visits
12. Women of child-bearing age and men with partners of child-bearing potential must agree to use two forms of contraceptive therapy throughout the course of the trial

7. Positive tests for syphilis
8. Any other clinically significant abnormalities on laboratory evaluation
9. Any condition that would compromise ability of undergoing lumbar puncture
10. Active systemic disease
11. Autoimmune disease (Hashimoto disease under control is allowed)
