StemCells, Inc. Awarded $20 Million From the California Institute for Regenerative Medicine for Alzheimer's Disease …

Posted: September 6, 2012 at 3:14 pm

NEWARK, Calif., Sept. 6, 2012 (GLOBE NEWSWIRE) -- StemCells, Inc. (STEM) today announced that the California Institute for Regenerative Medicine (CIRM) has approved an award to the Company for up to $20 million under CIRM's Disease Team Therapy Development Award program (RFA 10-05). The award is to fund preclinical development of StemCells' proprietary HuCNS-SC(R) product candidate (purified human neural stem cells) in Alzheimer's disease over a maximum four-year period, with the goal of filing an investigational new drug (IND) application for a clinical trial in that time. In July, CIRM approved a separate award to the Company under RFA 10-05 for up to $20 million to fund preclinical development of HuCNS-SC cells in cervical spinal cord injury.

"With the recent spate of late-stage clinical failures in Alzheimer's disease, it is clear that the field could benefit from alternative approaches to lessen the huge burden on families, caregivers and our healthcare system," commented Martin McGlynn, President and CEO of StemCells, Inc. "Our recently reported preclinical data, which showed that our neural stem cells restored memory and enhanced synaptic function in two animal models relevant to Alzheimer's disease, shows our approach has promise. We greatly appreciate the support from CIRM, which should help us accelerate our efforts to test our HuCNS-SC cells in Alzheimer's disease."

StemCells will evaluate its HuCNS-SC cells as a potential treatment for Alzheimer's disease in collaboration with Frank LaFerla, Ph.D., a world-renowned researcher in the field. Dr. LaFerla is Director of the University of California, Irvine (UCI) Institute for Memory Impairments and Neurological Disorders (UCI MIND), and Chancellor's Professor, Neurobiology and Behavior in the School of Biological Sciences at UCI.

Mr. McGlynn added, "CIRM's approval of two awards to StemCells illustrates the tremendous promise of our neural stem cell technology and the high degree of confidence in the world class team of scientists and clinicians who will be working to translate this technology into potential treatments and cures for these devastating diseases."

Cytomedix’s AutoloGel System Highlighted in Two Presentations at the 4th Congress of the World Union of Wound Healing …

Posted: September 5, 2012 at 3:20 pm

GAITHERSBURG, MD--(Marketwire -09/05/12)- Cytomedix, Inc. (CMXI), a fully integrated regenerative medicine company commercializing and developing innovative platelet and adult stem cell technologies for wound and tissue repair, today announced that the Company's AutoloGel System will be highlighted in an oral abstract and a poster presentation at the 4th Congress of the World Union of Wound Healing Societies (WUWHS 2012) being held from September 2-6, in Yokohama, Japan.

The AutoloGel System is a device for the production of autologous platelet rich plasma ("PRP") gel, and is the only PRP device cleared by the U.S. Food and Drug Administration ("FDA") for use in wound management.

"The Impact of Autologous Platelet Rich Plasma (PRP) Gel on Chronic Wounds" will be presented September 5th from 3:00 to 4:30 p.m. JST as part of the Tissue Engineering and Regenerative Medicines in Wound Healing session. The poster, OR 206, will be presented by Laura Parnell, MSc, CWS, Precision Consulting on behalf of Carelyn P. Fylling, RN, MSN, CWS, CLNC, Vice President of Professional Services of Cytomedix and lead author on the poster.

Key Study Findings (all data reflects mean outcomes)

The study concluded that AutoloGel PRP Gel "initiated rapid size reduction in long-standing non-healing wounds of multiple etiologies in multiple health care sites even in patients with compromised status."

In addition, Dr. Chugo Rinoie, DPM, ABPO, CWS, Chief of Podiatric Surgery, Wound Healing Center, Methodist Hospital of Southern California, Arcadia, Calif., and Medical Director, Millennia Wound Management, Inc., Los Angeles, will present Poster 125, entitled "Healing Complex, Severe Diabetic and Ischemic Wounds in Japan Using Platelet-Rich Plasma Gel" in the Exhibit Hall as part of the Diabetic Foot, Critical Limb Ischemia and Foot Care session.

"We are honored to have these two presentations of positive data in support of the use of AutoloGel to accelerate wound healing in a variety of chronic wounds selected for presentation at WUWHS 2012, as more than 1,200 abstracts were submitted for inclusion at this prestigious international Congress," noted Martin P. Rosendale, Chief Executive Officer of Cytomedix. "The data from these studies support and validate previous studies showing that AutoloGel significantly and reliably improves the rate of healing, speed and progress to healing as compared with previous experience with standard wound care alone. The complexity and co-morbidities associated with the wounds treated in these studies would have excluded them from any randomized controlled trial, making the findings from these real-world studies even more compelling."

"We believe we will continue to generate data such as these through the comprehensive collection of evidence we are undertaking through the Centers for Medicare and Medicaid Services' Coverage with Evidence Development program. We are confident such data will continue to strongly support the ongoing coverage for autologous PRP gel for the benefit of the various stakeholders in improving clinical wound care outcomes while lowering overall costs," added Mr. Rosendale.

About the Congress of the World Union of Wound Healing SocietyThe Congress of the World Union of Wound Healing Societies is held once every four years and provides an international forum for announcement of the latest research relating to wound healing that draws between 3,500 to 5,000 clinicians, researchers and professionals who serve the wound care markets around the world. The Congress also helps to ensure the exchange of information, the improvement and development of education, international person-to-person support and the promotion of industrial collaboration. The ultimate aim is to develop the field of wound healing. Despite the fact that "wounds" are a fundamental component and important target for surgery, there are still many factors that have yet to be clarified or fully understood.

Posted: September 4, 2012 at 11:13 pm

GAITHERSBURG, MD--(Marketwire -09/04/12)- Cytomedix, Inc. (CMXI) (CMXI), a fully integrated regenerative medicine company commercializing and developing innovative platelet and adult stem cell technologies, today announced that the Company's AutoloGel System was highlighted in a continuing education program at the Paralyzed Veterans of America Summit 2012 held August 28 to 30 at the Paris Las Vegas Hotel.

The AutoloGel System is a device for the production of autologous platelet rich plasma ("PRP") gel, and is the only PRP device cleared by the U.S. Food and Drug Administration ("FDA") for use in wound management.

The program, titled, "Platelet Rich Plasma (PRP) Gel for Wounds on Persons with SCI," was delivered by Laurie Rappl, PT, DPT, CWS, Clinical Development Liaison for Cytomedix. Ms. Rappl's discussion addressed the underlying mechanisms of action that allow the Company's physiologically relevant concentration of PRP in the AutoloGel System to accelerate healing in recalcitrant wounds in patients with Spinal Cord Injuries ("SCI"), and highlighted the clinical data demonstrating rapid reduction in wound area and volume, as well as reduction of undermining and sinus tracts/tunnels in non-healing wounds in patients with SCI.

"The physiology of SCI -- such as decreased blood flow, blood pressure and blood supply -- causes impairment at every step of the wound healing process. A physiologically relevant concentration of PRP has been shown to improve healing in even the hardest to treat chronic wounds in SCI patients," noted Ms. Rappl.

"It is especially rewarding for Cytomedix to have a continuing education program highlighting the benefits of the AutoloGel System for the treatment of chronic wounds in SCI patients. Pressure ulcers and other chronic wounds are persistent medical challenges that compromise the health and quality-of-life for these paralyzed patients," stated Martin P. Rosendale, Chief Executive Officer of Cytomedix. "Our clinical data demonstrates how the AutoloGel System's physiologically relevant concentration of PRP can rapidly restart the healing process in complex and chronic wounds, including wounds that were recalcitrant to other treatments."

Binding sites for LIN28 protein found in thousands of human genes

Posted: September 4, 2012 at 6:13 pm

Public release date: 4-Sep-2012 [ | E-mail | Share ]

Contact: Debra Kain ddkain@ucsd.edu 619-543-6163 University of California - San Diego

A study led by researchers at the UC San Diego Stem Cell Research program and funded by the California Institute for Regenerative Medicine (CIRM) looks at an important RNA binding protein called LIN28, which is implicated in pluripotency and reprogramming as well as in cancer and other diseases. According to the researchers, their study published in the September 6 online issue of Molecular Cell will change how scientists view this protein and its impact on human disease.

Studying embryonic stem cells and somatic cells stably expressing LIN28, the researchers defined discrete binding sites of LIN28 in 25 percent of human transcripts. In addition, splicing-sensitive microarrays demonstrated that LIN28 expression causes widespread downstream alternative splicing changes variations in gene products that can result in cancer or other diseases.

"Surprisingly, we discovered that LIN28 not only binds to the non-coding microRNAs, but can also bind directly to thousands of messenger RNAs," said first author Melissa Wilbert, a doctoral student in the UC San Diego Biomedical Sciences graduate program.

Messenger RNA or mRNA, are RNA molecules that encode a chemical "blueprint" for the synthesis of a protein. MicroRNAs (miRNAs) are short snippets of RNA that are crucial regulators of cell growth, differentiation, and death. While they don't encode for proteins, miRNAs are important for regulating protein production in the cell by repressing or "turning off" genes.

"The LIN28 protein is linked to growth and development and is important very early in human development," said principal investigator Gene Yeo, PhD, MBA, of the Department of Cellular and Molecular Medicine, the Stem Cell Research Program and the Institute for Genomic Medicine at UC San Diego. "It is usually turned off in adult tissue, but can be reactivated, for instance, in certain cancers or metabolic disorders, such as obesity."

Using genome-wide biochemical methods to look at the set of all RNA molecules across the transcriptome, the researchers found that LIN28 recognizes and binds to a known hairpin-like structure found on the let-7 family of miRNA, but surprisingly, this same structure is also found on mRNAs, allowing LIN28 to directly regulate thousands of targets.

"One of these targets actually encodes for the LIN28 protein itself. In other words, LIN28 helps to make more of itself," said Yeo. This process, known as autoregulation, helps to maintain a so-called "steady-state" system in which a protein positively regulates its own production by binding to a regulatory element of the mRNA for the gene coding it.

"Since these mRNA targets include those known to be involved in gene splicing, we also implicate LIN28 in the regulation of alternative splicing," said Wilbert, adding that abnormal variations in splicing are often implicated in cancer and other disorders.

Are some cell counts too good to be true? Why some companies’ product data may mislead.

Posted: September 2, 2012 at 3:59 pm


This is a cautionary tale about the need for robust product characterization and release specifications for all cell therapy products.
Background
While our food often has a list of ingredients, our drugs don't.  We rely on our regulatory agencies to rule on the safety of our drugs.  These agencies require drug manufacturers to submit to them the composition of their therapeutic compounds and then to comply with the product specifications.  It is this composition and these specifications which formed the basis of the clinical data evaluated by the agency and upon which the marketing approval is based.  Any deviation from those specifications requires a submission to the regulatory agency for review. Any deviation without such a submission is punishable.   
At the manufacturing site, as products come off the line they are subjected to a panel of product release tests to ensure each batch complies with the product specifications.
Specification compliance is a direct function of the consistency of the raw and ancillary materials, equipment, and operating procedures used in the manufacturing process.



Cell therapies present unique challenges when complying with this paradigm for several reasons only two of which I will mention here.  Firstly, it is not possible to achieve the level of product purification as one might with other therapeutic products.  Secondly, the product characterization is at a cellular rather than molecular level.

Autologous cell therapies present another set of unique challenge in this paradigm because of the notable patient-to-patient variability where the patient is also the donor of the raw material.  This often means there is a wider tolerance of heterogeneity in the product but it still must be within what has been proven to the regulatory agency as a safe and effective range.  


In cases where an autologous cell therapy is centrally manufactured, they are most often subjected to product release testing similar to that described above.  One notable difference, particularly for fresh products, is that the products may be shipped to the clinic and even administered before the full panel of test results are obtained.  This wold be considered highly unusual (if ever acceptable) with other types of products but is tolerated because of the time-sensitivity of these products and their high safety profile.


In the case of autologous cell therapy products produced at the bedside there is often not the same kind of product release discipline.  Often the regulatory agencies deal with the product consistency and specification compliance issue by ensuring that the cell processing device used point-of-care is validated to ensure the cellular product output is always within a specified range shown to be clinically safe and effective.


The Varying Degree of Product Characterization/Specification of Autologous GTP Cell Therapy Products


However - and now I get to the point of this blog post - for cell-based products, procedures and/or devices/kits which are not mandated to be formally approved by a regulatory agency before they can be commercially marketed, there is no product specification rigor.  Compliance with the Good Tissue Practice regulations and guidance is deemed to ensure safety.  In the United States, cell-based products which are deemed to be "minimally manipulated" and intended for "homologous use" are typically allowed to go straight to market with no formal approval.  Safety and clinical data is not required but is practically necessary to support physician adoption and, where applicable, reimbursement.  


This means that for these products there is a great deal of variability in terms of how much rigor companies apply in characterizing their product and then ensuring that each batch complies with the specifications they themselves have determined to be safe and effective. Again, where such products are manufactured in a centralized facility the likelihood of some release testing is greater.  However, those companies relying on a point-of-care processing kit or device business model that has not been deemed to require formal market approval, rarely (if ever) include product release testing.


The common criticism of these companies is that they simply do not know what they are injecting into patients because of the combination of the patient-to-patient donor variability, the lack of any disciplined product characterization or dosing studies, and the absence of any product release testing.  


This criticism is not equally levied at all autologous GTP products or companies - even those relying on point-of-care processing.  Of course some companies care and do a lot to try to ensure their product is well-characterized and that each batch complies with product specifications. This may involve the use of product release tests but can also involve the combination of pre-market research into the product characterization, safety, and dosing along with validation of the device/kit output.  In this way a company can say that within a very small margin, the output will be within the product specifications the company knows is safe and efficacious.


However, in a rush to get their device/kit to market some companies appear to care very little about the cell product characterization, validation of the output of their device/kit, or tying this data to optimal dose.


More concerning are those companies that appear to provide such data but it is wrong or meaningless.  What follows appears to potentially be a case study of precisely this problem. 


The INCELL Study 


This week I came across a fascinating white paper from Incell Corporation analyzing the output of adipose tissue processing kits of MediVet-America apparently demonstrating the inaccuracy of their cell counts (a common type of cell therapy product characterization) and calling into the question the cell count claims of Intellicell Biosciences (New York, NY) and Adistem (Hong Kong).


At the heart of the critique is the claim that the cell counting (product characterization) techniques employed by these companies counts as cells things (namely acellular micelles) which are not cells.

I encourage you to read the white paper in its entirety.  They corresponding author told me to watch for one or more papers which they are preparing for submission to peer-reviewed publications shortly.  Presumably these will rely on a larger data set and perhaps test other methodologies or technologies.


For the purposes of this blog, I've pulled what I believe are the most salient excerpts below:

Intrigued by the high cell numbers  (5 to 20 million cells/gram)  reported by kit/device manufacturers such as MediVet-America (Lexington, KY), Intellicell  Biosciences (New York, NY), and Adistem, Ltd. (Hong Kong) in adipose stem cell therapy compared to other methods (e.g., 
Chung,Vidal, and Yoshimura), INCELL staff conducted a research study to  investigate the high apparent yield of stem cells.  This initial work was focused  on SVF cells from the MediVet Kit, which is marketed to isolate adiposederived canine SVF and stem cells.

The cell yields reported for the Medivet Kits are five to more than ten times higher than the yields routinely obtained by INCELL from freshly harvested human or animal adipose tissue using our adipose tissue processing methods.  These yields are also tenfold or higher than those reported in the literature by most academic researchers (Chung-canine, Vidal–equine, Yoshimura–human).  Since these  cell counts are used to support stem cell dosing recommendations and cell banking, it is important to better understand why the cell numbers are higher.

...

A comparative analytical study of three dog donors of adipose tissue was designed to evaluate the cell yields using the MediVet Kit as an example of this class of isolation system. All  kit procedures were followed as per the instructions provided.  A brief overview of the different cell counting methods used, and the resultant cell counts, observations and explanations of the results observed, are described below

....

This study shows that incorrect counting of adipose derived SVF cells and the subset of regenerative stem cells can subsequently result in inaccurate dosing, both in direct therapeutic applications and in cryostorage of cells for future use.  The DAPI-hemocytometer cell count (manual) was considered the most accurate, but there are various sources of technical difficulties that  can lead to incorrect  cell numbers. The nature of adipose tissue itself with variability in dissociation by enzymatic digestion can all contribute to the outcomes. Fat tissue has a propensity to form acellular micelles and oils upon tissue disruption. Processing methods or reagents (e.g., Solution E or lecithins) can generate micelles that may be  erroneously  counted as cells. Autofluorescence and dye trapping or uptake by the micelles can lead to very high inaccurate cell counts when automated cell counting is used. 


In this study the most inaccurate counting came from the Cellometer. When used according to kitrecommended guidelines and on-site training provided by Nexelcom for counting  cells by the MediVet procedure, the Cellometer overstated the DAPI-hemocytometer cell count by up to 20X or more. The Coulter Counter protocols also led to incorrect, high cell numbers. Although the cell counts were still a bit high, the authors recommend the NucleoCounter, or similar equipment, as more acceptable for automated counting.  The manual hemocytometer-DAPI method is the most accurate, but requires a highly experienced cell biologist or technician to make accurate counts and  is not suitable for routine clinical use. 

...

Other companies also have claims of very high cell numbers when their processes are used. Adistem, like MediVet, states they add an emulsifying agent to their kits to assist in cell release, and they also use a light activation system. Their kits were not tested in this study but it is possible that the high cell numbers reported by Adistem are also incorrect and result from the same problems highlighted in this paper for the MediVet procedure. Ultrasonic energy, which is commonly used to manufacture micellular  liposome  structures and to disrupt and lyse cells, is  another potentially problematic procedure for counting and verifying viable, regenerative cells.  Intellicell 3uses ultrasonic energy to release cells from adipose tissue, and it is possible that resultant micelles or cell fragments contribute to the higher than expected cell numbers.  This assumption could be verified with additional studies.  

In summary, the authors caution that great care must be taken when using kits and automated cell counting for stem cell dosing and cryobanking of cells intended for clinical use. Overestimated  cell numbers would be a major confounding source of variation when efficacy of stem cells injected are compared as doses based on cell number and when cryostored cells are aliquoted for use based on 

specific cell numbers as a treatment dose.  Hopefully, this study will lead to more  reproducible counting and processing methods being reported in the literature, more inter-study comparability of cell doses to clinical outcomes,  more industry diligence to support claims, and more accurate counting for dosing stem cell therapies to patients.

 In Conclusion

Despite some of their other challenges, Intellicell, MediVet-America, and AdiStem (and others) have scored credibility points with some of my colleagues who have been impressed by the fact that they have incorporated product release criterion and testing technologies into their business model where their peer companies have not bothered.  This credibility may be quickly eroded if it turns out the results of their cell counts have been misleading.  For now it is a word of caution to do your own due diligence and/or not to fall into a similar product development/characterization trap.  Meanwhile, we will watch for the peer-reviewed papers.
