American CyroStem Warned by FDA to Stop Using Stem Cell Therapy Without Approval and to Correct Safety Issues

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. StudiesĀ suggest that mesenchymal stem cells can be used to alleviate symptoms and possibly treat several degenerative disorders, including multiple sclerosis. Atcell is aĀ 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 Parkinsonā€™s disease, amyotrophic lateral sclerosis, stroke, and multiple sclerosis, the FDA said in its release. It is administeredĀ intravenously, intrathecally (injection or infusion into the central nervous system) or by aerosol inhalation. The productĀ 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 extractedĀ using the companyā€™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,Ā providing compounds needed for the cells to survive and proliferate.Ā Stem cells put through this process are Ā ready to be used as therapy or to be stored for future use. A recent FDA inspection found that Atcellā€™s manufacturing steps are not in line withĀ 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, andĀ insufficient and inadequately validated product testing were also reported. ā€œThe 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,ā€ Peter Marks, director of the FDAā€™s Center for Biologics Evaluation and Research, said in the release. ā€œIn 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,ā€ 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 Atcellā€™s marketing, and failed to acknowledge that FDA approval was required, either by filing a biological license or investigational new drug application. ā€œAs part of our comprehensive policy framework for the efficient development and regulation of cell-based regenerative medicine, weā€™re going to be stepping up enforcement activities against those who manufacture and market products in ways that put patients at risk,ā€ said Scott Gottlieb, FDA commissioner. ā€œWe see great promise from the field of cell based regenerative medicine, but there are also novel risks,ā€ Gottlieb added. Healthcare professionals and patients who have used Atcell are asked to report any adverse events related to the treatment using the FDAā€™sĀ MedWatch Online Voluntary Reporting Form. Completed forms can be submitted online, or via fax to 1-800-FDA-0178. Ā

Link Between MS Therapy Tysabri and Melanoma Possible, an Adverse Reactions Watchdog Group Says

The multiple sclerosis therapy Tysabri could trigger melanoma, the Southern Network on Adverse Reactions (SONAR) has warned. Although its investigation failed to demonstrate that melanoma is more common among Tysabri-treated MS patients than in the general population, unusual features among the patients raise concerns about a possible link, the organization said. Contending that current monitoring efforts are inadequate, it suggested improvements that could generate a better understanding of the relationship between Tysabri treatment and cancer. The organization's report, published in the journal Cancer Medicine, was titled ā€œMelanoma complicating treatment with natalizumab for multiple sclerosis: A report from the Southern Network on Adverse Reactions, also known as SONAR." SONAR is an organization that was formed in the Southern United States in 2010 to investigate adverse drug reactions that regulators might not be aware of. Its goal is to reduce the time it takes between detecting an adverse reaction and have regulators act on it. A case that a SONAR investigator came across led to the group investigating possible links between Tysabri and melanoma. A 43-year-old woman developed melanoma in her urethra, the tubing that drains urine from the bladder, after being treated with Tysabri for about two years. Melanoma is most often a skin cancer that is related to sun exposure, but the woman had no skin lesions. After extensive surgery, she relapsed and died when the cancer spread to other parts of her body. She had declined anti-cancer treatment. The case prompt SONAR to look for similar cases. Its investigators found seven studies that involved Tysabri-treated MS patients developing melanoma. In addition, they looked through the U.S. Food and Drug Administrationā€™s Adverse Event Reporting System (FAERS) and the Tysabri Safety Surveillance Program. The surveillance program is part of the Tysabri Outcomes Unified Commitment to Health (TOUCH) database run by Tysabri's developer, Biogen, The research team found 137 cases in the FAERS database through April 1, 2014. The patients' average age was 45. Seventeen percent of the group developed tumors in locations not exposed to the sun, and nine died. The researchers said the database contained only about half the information it should have, such as tumor site, patients' family history of cancer, and earlier immunosuppressive treatment. Fifteen percent of the cases in the FAERS database were based entirely on information from the TOUCH database. Seventy-three percent were cases initially reported to FAERS but with TOUCH information added. Thirteen percent of the FAERS cases contained no additional information. Importantly, there was even less patient information in the TOUCH database than in the FAERS database. Out of eight items researchers believe a database should contain, TOUCH had information on two, on average. ā€œThe existence of the TOUCH Safety Surveillance Program, an FDA-mandated program, did not improve melanoma reporting,ā€ the team wrote. This shortage of data stymies research into possible links between Tysabri treatment and melanoma, the researchers said. As an example, although the death rates in the databases were low, there was no information about survival in many cases, which could lead to flawed survival estimates. The investigation noted that patients received a wide range of Tysabri doses before they were diagnosed with melanoma. While some received only one or a few injections, others had been treated for a long time. These observations do not seem to support a link between Tysabri and melanoma, the team said. ā€œA longer therapy duration would be expected if natalizumab caused melanoma via an immunologic pathway, unless existing nevi [lesions of the skin or mucus tissue] were already premalignant lesions,ā€ the researchers wrote. But other information the team found seemed to suggest a Tysabri-melanoma link. For example, the average age of melanoma patients was much lower than that reported in the National Cancer Instituteā€™s Surveillance, Epidemiology and End Results (SEER) database. The average age in the institute's database is 63, compared with 45 in the FAERS database and 41 in cases in academic journals. In addition, many patients developed tumors in unusual places not exposed to sunlight. Finally, the low melanoma death rate in Tysabri-treated patients differed from that seen in the general population. All these factors suggest that melanoma after Tysabri treatment could differ from other types of melanoma, the researchers argued. While the molecular workings of Tysabri might promote melanoma growth, studies so far have not found a relationship between the drug and this cancer. In fact, some studies suggest that MS patients, in general, have a lower risk of melanoma than others. The team said more information on patients could give researchers a better understanding of the potential relationship between Tysabri and melanoma. The implication was that the standard of reporting in the FAERS and TOUCH databases could improve. To minimize the risk of patients who receive Tysabri developing melanoma, the researchers offered a number of suggestions for IV centers, physicians, patients, and educational programs. For instance, they suggested that all patients should have a skin examination before the start of treatment, and regular physical and skin exams while receiving Tysabri. While noting that risk of infection and the development of tumors can occur with all immunosuppressive treatments, the team said more studies are needed to explore the risk of Tysabri-treated patients developing melanoma.
