Autologous hematopoietic stem cell transplantation, also known as aHSCT, has been shown to be safe and highly effective to treat patients with "aggressive" multiple sclerosis. Tested in 19 patients, transplantation of stem cells was found to induce clinically meaningful improvements in disability. These findings were shared at the 2018 Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles, California. aHSCT uses a patient’s own healthy bone marrow stem cells, in combination with a much less aggressive chemotherapy and/or radiation regimen, to prepare the patient for the transplant. Previous studies have suggested that aHSCT is an effective strategy to treat patients with highly active relapsing-remitting MS (RRMS) who do not respond to available disease-modifying therapies (DMTs), and international guidelines advocate for its use in patients with "aggressive" MS. To further demonstrate the potential of aHSCT as a treatment for "aggressive" MS, a research team evaluated its safety and effectiveness in MS patients who had not been treated previously with DMTs. A total of 19 patients were treated across several clinical centers: seven patients were from Sheffield, U.K., seven from Uppsala, Sweden, four from Ottawa, Canada, and one patient was from Florence, Italy. All patients received aHSCT between May 2004 and May 2017. In addition to aHSCT, patients were treated with BEAM (carmustine, etoposide, cytarabine, melphalan) chemotherapy plus antithymocyte globulin (ATG) to reduce transplant rejection, or with Cytoxan (cyclophosphamide) with ATG, or the triple combination of Cytoxan, ATG, plus busulfan as conditioning regimens. Patients had a median age of 33 years at diagnosis and received the aHSCT by a median time of nine years after symptom onset. They had a median disability score of 6.5 before the treatment, as determined by the Expanded Disability Status Scale (EDSS). After a median follow-up period of 30 months, patients had a median EDSS score of 2.0, which represented a median improvement of 2 points (the higher the score, the worse the patient's disability level). None of the patients had clinical relapse following the transplant of stem cells. Only three patients developed new brain lesions detectable by magnetic resonance imaging (MRI) at the first six-month follow-up evaluation, but no additional new lesions were detected in the following scans. The adverse effects reported during the study were comparable to those previously observed in similar treatments. No deaths related to the treatment were reported. Based on these preliminary results, the researchers concluded that aHSCT is “safe and highly effective in inducing rapid and sustain remission” in highly active MS, and "was associated with a significant improvement of [patient’s] level of disability.” “aHSCT should be considered as first line therapy in patients with ‘aggressive’ MS,” the team concluded. Another study presented at the AAN 2018 meeting further supports these findings, demonstrating the superior effectiveness of aHSCT over conventional DMTs for RRMS.

Blood Stem Cell Transplants Improve RRMS Patients’ Disability, Phase 3 Trial Shows Here’s yet another study that shows the benefits of autologous hematopoietic stem cell transplantation, or AHSCT — the procedure in which a patient’s own stem cells are harvested and used to rebuild the…
Blood stem cell transplants lead to significant improvements in relapsing-remitting multiple sclerosis patients’ disability, a Phase 3 clinical trial shows. The 110 patients who took part in the MIST study (NCT00273364) were having relapses after receiving standard therapies such as beta interferon, Copaxone (glatiramer acetate), Novantrone (mitoxantrone), Tysabri (natalizumab), Gilenya (fingolimod),…
Stem Cell Transplants of Greatest Benefit to RMS Patients at Earlier Disease Stages, Study Says
Stem cell transplants are most effective if done in young multiple sclerosis (MS) patients in early disease stages, who have not gone through several rounds of other treatments, according to a large study that followed transplant patients for more than five years. Study results also found that people with relapsing MS are much…
There is some good news about stem cell therapy. A just-published study concludes that one form of human stem cell therapy is more effective at treating multiple sclerosis than the best of the MS medications being used currently. The not-so-good news is that approval of this…
Autologous haematopoietic stem cell transplantation (aHSCT) has been used to stop autoimmune processes in multiple sclerosis (MS), although the treatment is not effective for every person. Now, an improved version of the technique is showing astonishingly good results, with patients free of both the need for treatment and the risk of relapses for…
People with MS who were involved in a long-term clinical trial are out and about enjoying a full and normal life with no signs of the disease. This follows their recovery from the stem cell transplants involving aggressive chemotherapy, or aHSCT as the procedure is known. Results of the clinical…
Stem cell treatment has been proven to both halt MS clinical relapses and the development of new brain lesions over a prolonged period, according to the results of a new study. The results, achieved in 23 out of 24 patients in a Phase 2 clinical trial, were published in…
Stem cell treatment of MS, which came under the spotlight at last week’s 16th Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC) when Dr. Mark Freedman discussed the procedure, is an exciting area within the development of therapies. Dr. Freedman, professor of medicine (neurology) at the…
