Резюме

This study is designed to treat your disease with an autologous stem cell transplant using a regimen of immune suppressant drugs and chemotherapy to reset your immune system and to determine if your disease will go into long-term remission.

Описание

The autologous stem cell transplant used in this research study is an investigational procedure that uses cyclophosphamide (chemotherapy), rabbit antithymocyte globulin (rATG) (a protein that kills the immune cells that are thought to be causing your disease), rituximab (a biologic drug that targets B cells of your immune system), and intravenous immunoglobulin (IVIg) (pooled IgG antibodies from plasma donors with immunomodulatory and anti-inflammatory effects), followed by return of your own previously collected blood stem cells (autologous stem cell transplant). One day of plasmapheresis will also be performed the day prior to admission for stem cell transplant to remove disease-causing antibodies. The ability of this experimental treatment to stop relapses and progression (worsening) of your NMOSD will be assessed.

ArmИнтервенция / лечение
Experimental: Hematopoietic Stem Cell Transplantation
Hematopoietic Stem Cell Therapy will be performed as follows: Autologous stem cells will be infused after conditioning with rituximab, cyclophosphamide, mesna, rATG (rabbit), and methylprednisolone. Granulocyte-colony stimulating factor (G-CSF) and intravenous immunoglobulin (IVIg) will be administered post-transplant.

16. Serum creatinine >2.0 mg/dl

17. Liver cirrhosis, transaminases >2x of normal limits, or bilirubin >2.0 mg/dl unless due to Gilbert's disease

18. Major hematological abnormalities such as platelet count < 100,000/μl or absolute neutrophil count (ANC) < 1000/μl

19. Active infection except asymptomatic bacteriuria

20. Presence of metallic objects implanted in the body that would preclude the ability of the patient to safely have magnetic resonance imaging (MRI) exams

21. Known hypersensitivity to mouse, rabbit, or E. coli derived proteins

22. Human immunodeficiency virus (HIV) positive

23. Hepatitis B or C positive

24. Use of natalizumab (Tysabri) within the previous six months

Резултат

Първични изходни мерки

1. Progression-Free Survival [5 years]

Disease progression defined as: 1.0-point increase in the Expanded Disability Status Scale (EDSS) on consecutive evaluations at least six months apart and not due to a non-NMO disease process. The EDSS scale ranges from 0 to 10 in 0.5 increments that represent higher levels of disability.

Вторични изходни мерки

1. Relapse-Free Survival [5 years]

Relapse defined as: Acute neurologic deterioration occurring after engraftment and lasting more than 24 hours, accompanied by objective worsening on neurological examination that are documented by a neurologist and not explained by fever, infection, stress, heat, drugs or related pseudo-exacerbation. Supportive confirmation by enhancement on MRI is preferred but not mandatory.

2. Expanded Disability Status Scale (EDSS) Improvement [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

The EDSS scale ranges from 0 to 10 in 0.5 increments that represent higher levels of disability. Improvement in EDSS is defined by both a 0.5 or 1.0 points sustained for more than 6 months

3. Scripps Neurological Rating Scale (NRS) Improvement [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

The NRS scale ranges from 0 to 100 in 1 point increments that represent lower levels of disability.

4. Improvement in Quality of Life [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

Measured using the short form (SF)-36 health survey.

5. Paced Auditory Serial Addition Test (PASAT) Improvement [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

The PASAT is a measure of cognitive function that specifically assesses auditory information processing speed and flexibility, as well as calculation ability. Improvement measured with the 2" and 3" versions

6. Ambulation Index Improvement [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

The subject's walk of 25 feet is timed and a score from 0 to 10 is assigned based on their walk/gait and/or assistance required.

7. 9 Hole Peg Test (9-HPT) Improvement [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

The 9-HPT is a brief, standardized, quantitative test of upper extremity function. Both the dominant and non-dominant hands are tested twice, with the total time to complete the task each time recorded and then averaged.

8. Change in NMO IgG (aquaporin-4) Antibody Titer [6 months, 1 year, 2 years, 3 years, 4 years, 5 years]

Evaluation of the antibody titer, looking for a change from positive to negative.
