“…Approximately 45 % of patients have a stable EDSS score at 5 to 7 years after HSCT [21,51,54]. Although the accumulated outcome data of HSCT for MS is largely from cohort studies that lack a randomized control group, most of the patients selected for HSCT had ongoing progression and had previously exhausted all other therapeutic options.…”

Reports from more than 600 hematopoietic stem cell transplants (HSCT) have appeared in the medical literature for the last 1 and one-half decades. The patient's own stem cells are harvested and stored temporarily while high doses of chemotherapy and biologics are used to destroy the auto-destructive immune system. The immune system is regenerated from the infused autologous hematopoietic stem cells. Increasing clinical experience has refined patient selection criteria and management in the peri-transplant period leading to a reduction in treatment-related complications. HSCT, when used to treat patients with aggressive highly active multiple sclerosis, can reduce or eliminate ongoing clinical relapses, halt further progression, and reduce the burden of disability in some patients, in the absence of chronic treatment with disease-modifying agents. The top 10 lessons learned from the growing experience using HSCT for the treatment of multiple sclerosis are discussed.Keywords Hematopoietic stem cell transplantation . Multiple sclerosis . Autoimmunity . Immune ablation There are published reports of more than 600 bone marrowbased transplants performed primarily for the treatment of multiple sclerosis (MS). This review will focus on why and how the hematopoietic stem cell transplantation (HSCT) procedure is used and discuss some of the lessons that can be gleaned from the experience of using HSCT to treat MS.MS is an organ-specific autoimmune disease that results in exclusive central nervous system (CNS) demyelination and axonal damage. Early on, multifocal localized pockets of inflammation lead to transient neurologic dysfunction manifesting as a series of relapses followed by remissions, usually with complete recovery owing to adequate CNS repair. However, as the damage accumulates, repair becomes inadequate and leads to incomplete resolution of disability, culminating in a neurodegenerative process amid a sea of smoldering and changing inflammation. This is probably the underlying state for the clinical stage of secondary progressive MS (SP-MS), a phase characterized by relentless and progressive accumulation of neurological disability with dwindling evidence of discrete relapses [1].Targeting inflammation with interferon-β, glatiramer acetate, natalizumab, fingolimod, and other immune-modulating agents reduces the frequency of relapses, but the impact on delaying the onset, preventing or slowing the tempo of SP-MS remains uncertain [2][3][4]. Several other drugs are in late stage clinical trials and may provide new alternatives for some patients with relapsing-remitting MS (RR-MS). However, despite these therapeutic advances, a subset of patients seem refractory and rapidly develop severe neurological impairment, whereas other patients may have a slower progression of illness that ultimately results in marked functional disabilities. Only a single agent, mitoxantrone, has been shown to temporarily halt or slow the tempo of SP-MS [5,6], but even then, this occurs only in SP-MS patients who have highly act...

“…More recent studies have shown that autologous AHSCT is effective at suppressing clinical and magnetic resonance imaging (MRI) disease reactivations 7–9 , can result in neurological improvement in patients with relapsing-remitting MS 7,8,10–12 and can halt all detectable CNS inflammatory activity for a prolonged period of time 13 . However, outcome assessments in the majority of studies were limited to a relatively short follow-up, and longer-term outcomes have been reported only from small case series 14–16 . It would therefore be important to examine in a large patient population the course of MS after AHSCT and the rates of risks and complications over longer term.…”

for the Multiple Sclerosis-Autologous Hematopoietic Stem Cell Transplantation (MS-AHSCT) Long-term Outcomes Study Group IMPORTANCE Autologous hematopoietic stem cell transplantation (AHSCT) may be effective in aggressive forms of multiple sclerosis (MS) that fail to respond to standard therapies. OBJECTIVE To evaluate the long-term outcomes in patients who underwent AHSCT for the treatment of MS in a large multicenter cohort.DESIGN, SETTING, AND PARTICIPANTS Data were obtained in a multicenter, observational, retrospective cohort study. Eligibility criteria were receipt of AHSCT for the treatment of MS between January 1995 and December 2006 and the availability of a prespecified minimum data set comprising the disease subtype at baseline; the Expanded Disability Status Scale (EDSS) score at baseline; information on the administered conditioning regimen and graft manipulation; and at least 1 follow-up visit or report after transplant. The last patient visit was on July 1, 2012. To avoid bias, all eligible patients were included in the analysis regardless of their duration of follow-up. Data analysis was conducted from September 1, 2014 to April 27, 2015.EXPOSURES Demographic, disease-related, and treatment-related exposures were considered variables of interest, including age, disease subtype, baseline EDSS score, number of previous disease-modifying treatments, and intensity of the conditioning regimen. MAIN OUTCOMES AND MEASURESThe primary outcomes were MS progression-free survival and overall survival. The probabilities of progression-free survival and overall survival were calculated using Kaplan-Meier survival curves and multivariable Cox proportional hazards regression analysis models. RESULTSValid data were obtained from 25 centers in 13 countries for 281 evaluable patients, with median follow-up of 6.6 years (range, 0.2-16 years). Seventy-eight percent (218 of 281) of patients had progressive forms of MS. The median EDSS score before mobilization of peripheral blood stem cells was 6.5 (range, 1.5-9). Eight deaths (2.8%; 95% CI, 1.0%-4.9%) were reported within 100 days of transplant and were considered transplant-related mortality. The 5-year probability of progression-free survival as assessed by the EDSS score was 46% (95% CI, 42%-54%), and overall survival was 93% (95% CI, 89%-96%) at 5 years. Factors associated with neurological progression after transplant were older age (hazard ratio [HR], 1.03; 95% CI, 1.00-1.05), progressive vs relapsing form of MS (HR, 2.33; 95% CI, 1.27-4.28), and more than 2 previous disease-modifying therapies (HR, 1.65; 95% CI, 1.10-2.47). Higher baseline EDSS score was associated with worse overall survival (HR, 2.03; 95% CI, 1.40-2.95). CONCLUSIONS AND RELEVANCEIn this observational study of patients with MS treated with AHSCT, almost half of them remained free from neurological progression for 5 years after transplant. Younger age, relapsing form of MS, fewer prior immunotherapies, and lower baseline EDSS score were factors associated with better outcomes. The results suppor...

“…Besides isolated reports of AHSCT being used for early treatment of highly aggressive relapsing inflammatory forms of MS 43,44 , the initial clinical studies of AHSCT in MS were conducted almost exclusively in patients with high levels of disability and progressive disease [45][46][47][48] as randomized controlled studies with these patients would be unethical.…”

Autologous haematopoietic stem cell transplantation for treatment of multiple sclerosis

et al. 2017

Autologous haematopoietic stem cell transplantation (AHSCT) is a multistep procedure that enables destruction of the immune system and its reconstitution from haematopoietic stem cells. Originally developed for the treatment of haematological malignancies, the procedure has been adapted for the treatment of severe immune-mediated disorders. Results from ~20 years of research make a compelling case for selective use of AHSCT in patients with highly active multiple sclerosis (MS), and for controlled trials. Immunological studies support the notion that AHSCT causes qualitative immune resetting, and have provided insight into the mechanisms that might underlie the powerful treatment effects that last well beyond recovery of immune cell numbers. Indeed, studies have demonstrated that AHSCT can entirely suppress MS disease activity for 4–5 years in 70–80% of patients, a rate that is higher than those achieved with any other therapies for MS. Treatment-related mortality, which was 3.6% in studies before 2005, has decreased to 0.3% in studies since 2005. Current evidence indicates that the patients who are most likely to benefit from and tolerate AHSCT are young, ambulatory and have inflammatory MS activity. Clinical trials are required to rigorously test the efficacy, safety and cost-effectiveness of AHSCT against highly active MS drugs
