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.

Atara Biotherapeutics recently published an update of the company’s quarterly financial results and operational highlights, including the advancement of its T-cell based immunotherapy strategies for multiple sclerosis (MS) and cancer. One of the investigational therapies featured in the report is ATA188, a potential treatment for MS.

A group of experts recently concluded that clinical trials are the best way to explore whether cell-based therapies are viable options for treating multiple sclerosis. In a newly published article, MS researchers reviewed evidence on a range of cell therapies, including stem cell transplants and delivery or stimulation of various cell types. Clinical trials, the panel argued, would be the optimal way to examine which types of cells should be used, how they should be delivered, and the types and disease stages the treatments are suitable for. The article focused on four types of cell-based treatments: autologous stem cell transplants, mesenchymal and related stem cell transplants, use of drugs to manipulate stem cells in the body to boost their ability to repair, and transplants of oligodendrocyte progenitor cells to trigger new myelin production. Loss of the myelin that protects neurons is a hallmark of MS. Such treatments hold promise to attain what current disease-modifying therapies in MS have not: halting the disease without lifelong treatment that has potential side effects, and regenerating damaged tissue. In addition to reviewing the evidence surrounding cell-based treatments, the expert group focused on the availability of the treatment options outside of controlled trials. “Media attention has resulted in some cases of misrepresentation and exaggeration of therapeutic claims for cell-based therapies for multiple sclerosis and other diseases,” the team wrote. This has caused patients to seek the treatments — paying out-of-pocket — at unregulated clinics. The panel noted that several drugs in development, including opicinumab, are aimed at promoting remyelination. In addition, drugs that are already approved for other conditions might have remyelinating properties, and might be repurposed to treat MS. Although studies are ongoing, the panel noted that it is unclear if the drugs do promote remyelination. Despite ongoing research and — in some cases — clinical use of cell-based therapies for MS, these treatments should be considered experimental, the expert group concluded. They again underscored the importance of clinical trials in providing a controlled environment for patients wishing to have cell therapy, as well as a source of evidence for the feasibility of these approaches.

Researchers managed to change the immune system — replacing inflammation with immune tolerance — in a mouse model of multiple sclerosis (MS) using so-called quantum dots, or nano-sized particles carrying pieces of myelin. Experiments with this advanced technological solution may help researchers design MS therapies that are based on promoting regulatory T-cells rather…
