High Dose Chemo With Stem Cell Transplant as Treatment for Multiple Sclerosis That Failed Prior Treatment

November 21, 2013 updated by: Seah Lim M.D.

A Phase II Study of High Dose Chemotherapy With Autologous Hematopoietic Progenitor Cell Transplant for Multiple Sclerosis That Failed at Least Two Lines of Therapy

The purpose of this study is to evaluate the toxicity and the effectiveness of high dose chemotherapy with HPC transplant Multiple Sclerosis that has failed at least two lines of therapy

Study Overview

Detailed Description

Multiple sclerosis is an inflammatory autoimmune disease characterized by loss of myelin and axonal damage, having typical contrast-enhanced MRI foci as an imaging counterpart. MS shows three main patterns of clinical course: relapsing/remitting, primary progressive and secondary progressive.Concerning disease pattern, secondary progressive is the standard indication, to avoid overtreatment in relapsing/remitting patients or ineffectual treatment in primary relapsing patients.

Currently, MS is the most common autoimmune disease that have been treated with autologous HPC transplants (Fagius et al, 2009; Burt et al, 2009; Saccardi et al, 2006). More than 350 consecutive cases have been reported by the EBMT over the last decade. Most patients who underwent autologous HPC transplant for MS in the early studies had secondary progressive MS, and relatively fewer had relapsing remitting disease, with a Kurtzke Expanded Disability Status Scale (EDSS) of 3.0-9.5 at the time of transplant. Significant objective and subjective improvements have been reported in up to 70% of these patients.

The following conditioning regimens will be used, with Alemtuzumab, Fludarabine, and Cyclophosphamide will be used for all patients. Prophylaxis of Acyclovir, Levaquin, and Fluconazole will be given to prevent infections. The autologous HPC will be infused within 48-72 hours of completing the chemotherapy. The patients will receive additional supportive care medications and treatments as necessary. Neutrophil engraftment will be defined as the day on which the ANC rises to > 500 cells/ml for two consecutive days. Platelet engraftment will be defined as the first day on which the platelet count rises to > 20,000/ml over a 7-day interval without transfusion support.

Description

Inclusion Criteria:

Age between 18-60, inclusive

Patients carry a diagnosis of multiple sclerosis, according to the McDonald's criteria for diagnosis (Polman et al, 2011).

Must have a neurologist providing the primary care for the MS and be willing to be evaluated for the multiple sclerosis by the two neurologists who are the co-investigators in the protocol.

Must be documented to be HIV negative.

An EDSS of 3.5 - 5.5

Patients must be able to give written consent.

Inflammatory disease despite primary disease modifying therapy with at least 6 months of interferon and another disease modifying therapy, including fingolimod,glativamir, natalizumab, and mitoxantrone. Failure is defined as two or more clinical relapses with documented neurologic changes (excluding sensory changes) within the year prior to the study. (NOTE: Relapses must have required treatment with corticosteroids). Failure may also be defined as one relapse (excluding sensory changes) treated with methylprednisone and, on a separate occasion within the previous 12 months, evidence of active inflammation (i.e. gadolinium enhancement on MRI scan of the CNS).

No previous history of allergic reaction to cyclophosphamide, G-CSF or mesna

Patients must not be pregnant

Failure to accept or comprehend irreversible sterility as a potential side effect of therapy.

Life expectancy of more than 6 months

No evidence of myelodysplastic syndrome on peripheral blood smear

Not allergic to cyclophosphamide, mesna, fludarabine or alemtuzumab

Baseline serum creatinine must be <1.5 mg/dL, left ventricular ejection fraction >55%, adequate pulmonary functions (oxygen saturation at room air of >90%), and AST and ALT not > 2x upper limits of normal, and no history of previous or active malignancy, except for localized cutaneous basal or squamous cell carcinoma in situ of the cervix.

Exclusion Criteria:

Diagnosis of primary progressive MS.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Single Arm
Conditioning regimens with Alemtuzumab, Fludarabine, and Cyclophosphamide will be used for all patients.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To evaluate the toxicity of autologous HPC transplant in patients with multiple sclerosis that have failed at least two lines of disease modifier therapy
Time Frame: At 5 years post transplant
All follow-up appointments will be carried out at Texas Oncology-Amarillo Cancer Center. Patients will be monitored for clinical toxicities and using laboratory blood tests for renal functions, hepatic functions, and bone marrow functions at At discharge post-transplant, then again at 6 weeks, 3 months, 6 months, 9 months, 12 months and after that 6 monthly until death..
At 5 years post transplant

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To evaluate the effectiveness of high dose chemotherapy with HPC transplant for multiple sclerosis sclerosis that has failed at least two lines of therapy
Time Frame: Assessed at baseline, tat 3 months, 6 months, 9 months, 12 months, and then after every 12 months until death
hen rechecked Neurologic evaluations will be carried out in the offices of the two neurology co-Investigators and the information provided to the transplant physicians for record. Patient will also undergo a repeat MRI scan at 3 months, 6 months, 9 months, 12 months, and then after every 12 months until death, after the transplant to evaluate changes in the number of MS plaques. Subsequent MRI scan will be determined by the patient's neurologist as is needed clinically.
Assessed at baseline, tat 3 months, 6 months, 9 months, 12 months, and then after every 12 months until death
