Autologous hematopoietic stem cell transplant is better than disease-modifying therapies (DMT) at reducing the risk of disease progression in patients with relapsing-remitting multiple sclerosis (RRMS), results from the MIST clinical trial show. The study “Effect of Nonmyeloablative Hematopoietic Stem Cell Transplantation vs Continued Disease-Modifying Therapy on Disease Progression…

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.

Autologous non-myeloablative hematopoietic stem cell transplant was found to be significantly better at reducing risks for disability in relapsing-remitting multiple sclerosis (RRMS) patients compared to disease-modifying drug (DMD) therapies, interim results of the MIST clinical trial show. The results will be shared at the 2018 Annual Meeting of the American…

American CryoStem has received a warning letter from the U.S. Food and Drug Administration (FDA) for marketing its adipose-derived stem cell product Atcell without required regulatory approval, and for "significant deviations" from manufacturing processes that potentially raise safety concerns. The company has 15 working days to respond to the concerns raised by the agency and detail how they will be corrected, or risk "enforcement actions," the FDA said in a Jan. 4 press release. Studies suggest that mesenchymal stem cells can be used to alleviate symptoms and possibly treat several degenerative disorders, including multiple sclerosis. Atcell is a therapy based on the ability of mesenchymal stem cells isolated from adipose tissue (fatty tissue) to transform into a subset of mature cells, which include adipose cells, bone cells, and cartilage cells. Although not approved for use, Atcell is being distributed directly to physicians to treat patients affected by several life-threatening diseases, including Parkinson’s disease, amyotrophic lateral sclerosis, stroke, and multiple sclerosis, the FDA said in its release. It is administered intravenously, intrathecally (injection or infusion into the central nervous system) or by aerosol inhalation. The product is designed to be used in the same individual (autologous use) the cells are collected from, an approach intended to reduce risk. The cells are extracted using the company’s proprietary Cellect collection system. They are then expanded in the laboratory using the company's ASCelerate SF-M serum free (animal-product free) media, providing compounds needed for the cells to survive and proliferate. Stem cells put through this process are  ready to be used as therapy or to be stored for future use. A recent FDA inspection found that Atcell’s manufacturing steps are not in line with current good manufacturing practice requirements. Specifically, the manipulation of the adipose tissue was more than "minimal," the FDA reported, changing "relevant characteristics" of the original tissue that could introduce contamination by microorganisms or product defects and represent a "risk of harm" to patients. Because of this manipulation, FDA review is required by law to ensure Atcell's safety and efficacy, the agency said. Evidence of an inadequately controlled manipulation environment, lack of control of components used in production, and insufficient and inadequately validated product testing were also reported. “The use of Atcell raises potential significant safety concerns, due in part to the fact that there is little basis on which to predict how the product will perform in a patient,” Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said in the release. “In addition, this product may also cause harm to patients who may put their trust in an unproven therapy and make the decision to delay or discontinue medical treatments proven to be safe and effective,” Marks added. American CyroStem, based in New Jersey, did respond to observations raised by the FDA at the time of its inspection. But they were found inadequate to support Atcell’s marketing, and failed to acknowledge that FDA approval was required, either by filing a biological license or investigational new drug application. “As part of our comprehensive policy framework for the efficient development and regulation of cell-based regenerative medicine, we’re going to be stepping up enforcement activities against those who manufacture and market products in ways that put patients at risk,” said Scott Gottlieb, FDA commissioner. “We see great promise from the field of cell based regenerative medicine, but there are also novel risks,” Gottlieb added. Healthcare professionals and patients who have used Atcell are asked to report any adverse events related to the treatment using the FDA’s MedWatch Online Voluntary Reporting Form. Completed forms can be submitted online, or via fax to 1-800-FDA-0178.

Advertising for stem cell therapies not supported by clinical research — often made directly to patients and sometimes promoted as a "cure" for diseases like multiple sclerosis or Parkinson's — is a growing problem that needs to be addressed and regulated, a team of leading experts say, calling such "stem cell tourism" potentially unsafe. Stem cell tourism is the unflattering name given to the practice of encouraging patients to travel outside their home country to undergo such treatment, typicaly at a private clinic. The article, titled "Marketing of unproven stem cell–based interventions: A call to action" and recently published in the journal Science Translational Medicine, was co-authored by scientists with universities and hospitals in the U.S., Canada, U.K., Belgium, Italy, Japan, and Australia. It focuses on the global problem of the commercial promotion of stem cell therapies and ongoing resistance to regulatory efforts. Its authors suggest that a coordinated approach, at national and international levels, be focused on "engagement, harmonization, and enforcement in order to reduce risks associated with direct-to-consumer marketing of unproven stem cell treatments." Treatments involving stem cell transplants are now being offered by hundreds of medical institutions worldwide, claiming efficacy in repairing tissue damaged by degenerative disorders like MS, even though those claim often lack or are supported by little evidence . They also noted that the continued availability of these treatments undermines the development of rigorously tested therapies, and potentially can endanger a patient's life. The researchers emphasize that tighter regulations on stem cell therapy advertising are needed, especially regarding potential clinical benefits. They support the establishment of international regulatory standards for the manufacture and testing of human cell and tissue-based therapies. "Many patients feel that potential cures are being held back by red tape and lengthy approval processes. Although this can be frustrating, these procedures are there to protect patients from undergoing needless treatments that could put their lives at risk," Sarah Chan, a University of Edinburgh Chancellor’s Fellow and report co-author, said in a news release. Chan and her colleagues are also calling for the World Health Organization to offer guidance on responsible clinical use of cells and tissues, as it does for medicines and medical devices. "Stem cell therapies hold a lot of promise," Chan said, "but we need rigorous clinical trials and regulatory processes to determine whether a proposed treatment is safe, effective and better than existing treatments." According to the release, the report and its recommendations followed the death of two children at a German clinic in 2010. The clinic has since been shut down. Certain stem cell therapies — mostly involving blood and skin stem cells – have undergone rigorous testing in clinical trials, the researchers noted. A number of these resulted in aproved treatments for certain blood cancers, and to grow skin grafts for patients with severe burns. Information about the current status of stem cell research and potential uses of stem cell therapies is available on the website EuroStemCell.
