Groundbreaking stem cell research requires legal certainty (Other …

By Denver Post Editorial Board

Medical advances come so fast and furious these days, it might be easy to lose perspective as to how transformative these discoveries can be.

Limb and even face transplants are possible, as is tissue regeneration. And joint replacement well, that has become almost routine.

Against this backdrop, its understandable to perhaps have overlooked an announcement last week that researchers found no detectable HIV virus levels in two stem-cell transplant patients who had previously tested positive for HIV.

Its too early to use the word cure, but the implications are breath-taking. At the very least, the findings could be an important stepping stone on the path to a cure for a virus that has led to more than 30 million deaths worldwide.

The life-changing potential of the discovery brings to mind the need for federal lawmakers to pass legislation cementing into law the Obama administrations rules on embryonic stem-cell research. As it stands, these sensible rules could be modified by a successive administration.

U.S. Rep. Diana DeGette, D-Colo., reintroduced such a measure several weeks ago, and we hope it passes. Congress passed similar measures twice before, but they were vetoed by then-President George W. Bush.

To be clear, the type of stem-cell therapy used in the HIV research a bone marrow transplant is different from embryonic stem-cell research and doesnt typically spark the kind of controversy that embryonic stem-cell research engenders. And thank goodness.

But the potential for medical breakthroughs from embryonic stem-cell research that could help people suffering from debilitating diseases and conditions such as Parkinsons Disease and juvenile diabetes is similarly inspiring.

As research institutions consider investing in the human capital and infrastructure necessary to carry out embryonic stem-cell research, having legislative clarity would make those expenditures more palatable.

ViaCyte, Inc. raises $10.6 Million in a Private Financing to Support Clinical Development of its Cell Therapy Product …

SAN DIEGO, July 10, 2013 /PRNewswire/ --ViaCyte, Inc., a leading regenerative medicine company focused on developing new approaches to treat major diseases through the application of a stem cell-derived cell therapy, announced today that it completed a private equity financing transaction, providing the Company $10.6 million through the sale of Series C-1 Preferred Stock, together with warrants to purchase stock. The financing, conducted as a rights offering to ViaCyte Series B and C Preferred Stock holders, included the Company's largest existing investors - Johnson & Johnson Development Corporation, Sanderling Ventures and Asset Management Company (Johnson Trust).

(Logo: http://photos.prnewswire.com/prnh/20121026/LA00871LOGO-a)

This funding serves as a match for a $10.1 million Strategic Partnership Award (SPA) that was approved last October by the California Institute for Regenerative Medicine (CIRM) to support clinical evaluation of VC-01, ViaCyte's promising encapsulated cell-therapy product being developed as a transformative therapy for patients with type 1 and insulin-dependent type 2 diabetes. In addition, ViaCyte may sell additional shares of Series C-1 Preferred Stock and warrants in one or more subsequent closings that may occur during the remainder of 2013.

The Company will use the funds to pursue clinical development of VC-01. VC-01 is a development-stage product that consists of pancreatic precursor cells (designated PEC-01) manufactured through directed differentiation of stem cells sourced from a proprietary human embryonic stem cell line, and encapsulated in a proprietary, immune protective medical device (the ENCAPTRA device). When implanted under the skin, the encapsulated cells are designed to further differentiate into insulin and other hormone-producing pancreatic cells that regulate blood glucose in a manner similar or identical to a normal pancreas.

Kevin D'Amour, Ph.D., ViaCyte's Chief Scientific Officer, recently provided an update on VC-01 during a presentation at the 73rd Scientific Sessions of the American Diabetes Association entitled Development of an Encapsulated Stem Cell-Based Therapy for Diabetes. The presentation highlighted the tremendous progress ViaCyte has made in the preclinical development of VC-01. ViaCyte is currently planning to file its Investigational New Drug (IND) application with the Federal Drug Administration (FDA) to initiate clinical trials in patients with type 1 diabetes early next year. If VC-01 performs in humans as it has in preclinical studies, it could significantly alleviate or eliminate the challenges and complications for Type 1 diabetics who manage their disease through careful control of diet, monitoring of blood glucose levels and injection of insulin.

The SPA from CIRM provides ViaCyte with $10.1 million to support the clinical study planned for next year and complements previous funding from CIRM. This award reflects CIRM's commitment to follow promising science through the progressive stages of product development. The Company has also received and continues to receive both scientific and financial support for the development of VC-01 from JDRF.

Paul Laikind, Ph.D., ViaCyte's president and chief executive officer, said, "We are very gratified by the continued support of our investors and CIRM as we prepare to evaluate the safety and efficacy of VC-01. This promising product candidate has the potential to vastly improve the lives of millions of patients who currently require insulin injections to survive. Moreover, success of VC-01 will validate ViaCyte's proprietary, stem cell-derived cell therapy platform that has multiple applications, as well as demonstrate the full utility of the Company's encapsulation technology for enabling allogeneic cell therapy treatments."

About ViaCyte

ViaCyte, a private company that has emerged as a leader in the field of regenerative medicine, is currently focused on developing a novel cell therapy for the treatment of diabetes. The Company's lead product is based on the production of pancreatic progenitors derived from human pluripotent stem cells. These cells are implanted in a durable and retrievable encapsulation device. Once implanted and matured, these cells are designed to secrete insulin and other regulatory factors in response to blood glucose levels. ViaCyte's goal for this potentially transformative diabetes product is long term insulin independence without immune suppression, and without risk of hypoglycemia and other diabetes-related complications.

ViaCyte is headquartered in San Diego, California with additional operations in Athens, Georgia. The Company is funded in part by CIRM and JDRF.

Stem Cell Therapy for Knee Pain: Safer than Surgery

TAMPA, Fla., July 9, 2013 /PRNewswire/ -- Stem Cell Therapy for knee joint pain has been involved in multiple clinical trials worldwide. In the United States trials for knee arthritis and back pain with degenerative disc disease have undergone safety trials and phase studies for effectiveness. The safety profile for stem cell therapy in joints has been proven. Adverse effects are not seen as related to the stem cells. These studies were conducted with allogenic (other people's) stem cells. Naturally, if using your own stem cells, the issues which may be raised from someone else's stem cells is not a concern, and are therefore even safer. There are no immune rejection issues or communicable diseases that can be obtained by using your own cells.

Stem Cell Therapy for joints also do not carry surgical risks such as anesthesia, there is no greater risk for other postoperative complications such as blood clots, infections, or need for revision surgery if it is unsuccessful. Dr. Dennis Lox, a Regenerative and Sports Medicine physician in the Tampa Bay, Florida area (www.drlox.com), comments, "Surgery for joint replacement does carry some significant risks, as this is a highly invasive surgery. Knee and other joint replacement surgery consent forms do include the complication of death. More common problems are infection and blood clots. Stem Cell Therapy injections for joints are no more difficult than injecting cortisone into the knee," states Dr. Lox."There is preparation involved to get to that point, however the injection can be a simple, same-day, office-based procedure."

Dr. Lox notes, "Stem Cell Therapy for joint repair has been used for acute and chronic injuries, knee meniscal tears, loss of knee joint cartilage, and to stop the progression of degenerative arthritis. Even avascular necrosis (AVN) or osteonecrosis has been treated with Stem Cell Therapy. The secondary arthritis from joint collapse in avascular necrosis (AVN) can be significant leading to knee joint replacement. The useof stem cells is becoming a more common alternative to joint replacement."

Dr. Lox further notes, "Some patients may have already had one knee joint replaced with a bad outcome, and wish to avoid a second knee replacement. Others may not be healthy enough. Some medical disorders such as bad hear ailments may preclude having a knee replacement. In these cases, having a regenerative medicine procedure is an attractive, conservative option. Patients who are not medically suited for joint or knee replacement are generally good candidates for Stem Cell Therapy. The pursuit of conservative options in patients who wish to avoid surgery for joint disorders, may find Stem Cell Therapy as an attractive alternative."

Stem Cell Therapy for Knee Pain: Safer than Surgery

Promise and caution shown in ongoing research into stem cell treatment of strokes

Public release date: 9-Jul-2013 [ | E-mail | Share ]

Contact: Dwight Angell dwight.angell@hfhs.org 313-850-3471 Henry Ford Health System

DETROIT While stem-cell therapy offers great promise for the treatment of stroke, much research remains to be done to show its long-term effectiveness and to understand the potential for dangerous side effects.

These are the conclusions drawn by Henry Ford Hospital neurologists Jing Zhang, M.D., Ph.D., and Michael Chopp, Ph.D., scientific director of the Henry Ford Hospital Neuroscience Institute, in a review of their own and other current research into the next-generation treatment of one of the leading causes of death and disability around the world. The article has been accepted for publication by Expert Opinion on Biological Therapy.

Most strokes are ischemic, meaning they occur when an artery to the brain is blocked, stopping the flow of vital, oxygen-rich blood. The blockage can be caused by a blood clot, air bubble or other mass in the blood stream.

"This touches off many complicated reactions," Dr. Zhang explains. "Nerve circuits are disrupted. Chemical processes within cells are disturbed. The blood-brain barrier, which protects the brain from a wide range of harmful invasions, including infection, is damaged.

"As a result, many stroke survivors are left with permanent neurological and physical disability. And this leads to a huge social and economic burden."

Current stroke treatment focuses on restoring blood flow to the brain to stop further cell and tissue damage. However, Drs. Zhang and Chopp write, only one drug has FDA approval for the clinical treatment of stroke.

Called tPA, it's an enzyme that works on destroying or dissolving the blockage that caused the stroke. Although it can be effective, it also has downsides, they note.

The time in which tPA can be helpful is short at most only four and a half hours after the stroke. This is probably the reason less than 10 percent of stroke patients are treated with tPA.

Stemedica Advances to Phase II Stroke Trial with Lead Product Stemedyne-MSC

San Diego, CA (PRWEB) July 10, 2013

Stemedica Cell Technologies, Inc., a leader in adult allogeneic stem cell manufacturing, research and development, announced today the completion of enrollment and treatment of patients in a Phase I study with Stemedicas lead product Stemedyne-MSC. These specially formulated ischemic adult allogeneic mesenchymal stem cells have been manufactured at Stemedicas cGMP compliant facility and have been successfully used to treat patients in an ischemic stroke study: A Phase I/II, Multi-Center, Open-Label Study to Assess the Safety, Tolerability and Preliminary Treatment Efficacy of a Single Intravenous Dose of Allogeneic Mesenchymal Bone Marrow Cells to Subjects with Ischemic Stroke.

The primary goal of the Phase I study was to assess the safety and tolerability of treatment with Stemedyne-MSC as determined by the incidence and severity of adverse events, clinically-significant changes on clinical laboratory tests, vital signs, physical and neurologic examinations in patients with a clinical diagnosis six months post ischemic stroke. The secondary goal was to assess the clinical effects of treatment on neurologic, functional, and motor deficits.

Fifteen patients were treated in this dose escalation Phase I study. Patients received one dose of Stemedyne-MSC via intravenous administration. An Independent Data Safety Monitoring Board reviewed safety data for subjects including adverse events, laboratory data and vital signs. Based on the review, they unanimously voted for the trial to proceed to Phase II.

Michael Levy, MD, PhD, FACS, the Principle Investigator and John Crawford, MD, Co-Investigator at the University of California, San Diego (UCSD) clinical site commented, We are optimistic that we will continue to see efficacy in Phase II based on improvements in levels of alertness and functional speech we have observed, especially in those patients with significant injuries.

Nabil Dib, MD, MSc, FACC, the Co-Investigator at the Mercy Gilbert Medical Center, Chandler Regional Medical Center in Gilbert, Arizona site commented, We are extremely excited about the Data Safety Monitoring Boards report on the first 15 patients treated and are encouraged by our preliminary observations of the improvements of the patients clinical symptoms. We look forward to completing patient enrollment into Phase II and the final analysis of this very important clinical trial. Cell therapy potentially has significant application in stroke patients that may change the way that we treat patients with cerebrovascular accidents.

Lev Verkh, PhD, Stemedicas Chief Regulatory and Clinical Development Officer, commented, Stemedica achieved this significant milestone by demonstrating the safety of the product at all doses studied in this trial. We are also encouraged that this treatment resulted in clinical benefits in patients with this diagnosis. The Phase II portion of this trial is open for enrollment (http://clinicaltrials.gov/ct2/results?term=stemedica).

Nikolai Tankovich, MD, PhD, FASLMS, President and Chief Medical Officer of Stemedica noted, Our current and planned clinical trials are directed toward the entire spectrum of ischemic disease, from the early onset of the vascular damage in metabolic syndrome, to the acute damage of myocardial infarction and chronic damage as evidenced by the stroke patients in this trial. By expanding Stemedyne-MSC cells in our proprietary low oxygen process, we produce MSCs that have higher levels of the critical factors necessary for vascular repair as compared to cells expanded in normal oxygen.

More than 800,000 Americans suffer a stroke annually and according to the American Heart Association, stroke is the fourth leading cause of death - costing an estimated $73.7 billion in 2010 for stroke-related medical costs and disability.

About Stemedica Cell Technologies, Inc. http://www.stemedica.com Stemedica Cell Technologies, Inc. is a specialty bio-pharmaceutical company that is committed to the manufacturing and development of best-in-class allogeneic adult stem cells and stem cell factors for use by approved research institutions and hospitals for pre-clinical and clinical (human) trials.

Stem cell therapy: Future of medicine?

by Rappler.com Posted on 07/09/2013 9:42 PM |Updated 07/10/2013 3:51 PM

MANILA, Philippines - Everyone is talking about stem cell therapy. But scammers and swindlers are also taking advantage of the fad, prompting the Health Department to step in. Buena Bernal reports.

Its the new medical buzzword in the Philippines. Stem cell therapy is a procedure which uses repair cells found in the body to replace old cells. Dr Florencio Lucero started doing the procedure 6 years ago.

DR FLORENCIO LUCERO, STEM CELL TRANSPLANT SURGEON: Stem cells can help degenerative diseases. Some people who have serious illnesses, and they cannot find any solution to their condition, they seek this kind of treatment, because it can improve their condition. But not a cure. It cannot cure.

Pilar Vazquez who went through a mild stroke says she felt energized after undergoing the treatment.

PILAR VAZQUEZ, STEM CELL TRANSPLANT PATIENT: Stem cell is very good. I did not feel pain or what. Everything is very good. Before, I dont [always] talk. Now, I always talk. Thats a very good difference, because now they say, Ay si Mommy, ang galing galing niyan, parating nagsasalita!

But stem cell therapy became controversial after 3 government officials allegedly died from the treatment, while another official filed charges against his German doctor for his botched treatment last year. Food and Drug Administration director Dr. Kenneth Hartigan Go says right now, stem cell therapy is allowed but under investigation.

DR KENNETH HARTIGAN-GO, DIRECTOR, FOOD AND DRUG ADMINISTRATION: We are keeping an objective mind and saying, okay, if this is investigational, go ahead. And then we have to see outcome, say, within a period of a time whether the product actually works or not.

The Department of Health cautions the public from engaging in prohibited forms of the treatment -- those that are performed outside accredited facilities and those that source stem cells from human embryos. Health Secretary Enrique Ona says he does not want to stifle the innovation but there must be regulation.

Sports Medicine and Stem Cells: Athletes are ready for New Era of Treatment

TAMPA, Fla., July 9, 2013 /PRNewswire/--As new medical frontiers are forged, their place in sports medicine will be assured if athletes can recover or heal faster. This concept has not been lost in the dawn of Regenerative Medicine. This new age has emerged in which regenerative stem cell treatments are being applied to blindness, spinal cord injuries and congestive heart failure. It is no wonder that elite athletes such as Peyton Manning turned to stem cells when his neck wasn't healing. http://www.drlox.com

So what is it that makes the allure of stem cells attractive to high caliber athletes? According to Dr. Dennis Lox, a Sports Medicine and Regenerative specialist, in the Tampa Bay, Florida area, stem cells have unique capabilities for injured athletes. First the stem cells are very effective at alleviating inflammatory responses seen in chronic injuries. By blocking and altering the mechanisms in which inflammation occurs, some chronic injuries may heal. Dr. Lox then comments that, the stem cells are also at the same time regenerative cells that may heal by releasing factors that allow healing to occur, or trophic effects. Lastly, the stem cells may allow regeneration of injured tissue. All these mechanisms, Dr. Lox stresses, cannot be achieved by cortisone injections, or commonly prescribed anti-inflammatory medications. http://www.drlox.com

The unique way in which regenerative therapies such as Platelet Rich Plasma (PRP) and stem cells, exert effects on injured tissues will always be seen positively as athletes search for better and quicker healing treatments. Also, athletes need to be concerned with career longevity. The possible fountain of youth that repairing injured muscles and joints may hold with stem cell therapy makes it an attractive option. No adverse effects have been reported in clinical trials using stem cells for knee arthritis. The same cannot be said for knee surgery. The upside to minimizing further joint injury by avoiding surgery, may deter accelerated arthritis development. Dr. Lox notes a player's career may be lengthened by early repair of knee injury, and preventing arthritis development. These are two goals of regenerative medicine, and in some athletes mind two reasons to consider stem cell therapy.

Microparticles create localized control of stem cell differentiation

Jul 09, 2013 Georgia Tech/Emory University Associate Professor Todd McDevitt and graduate student Anh Nguyen make microparticles to be used for delivering growth factors to stem cells. Credit: Rob Felt

Before scientists and engineers can realize the dream of using stem cells to create replacements for worn out organs and battle damaged body parts, they'll have to develop ways to grow complex three-dimensional structures in large volumes and at costs that won't bankrupt health care systems.

Researchers are now reporting advances in these areas by using gelatin-based microparticles to deliver growth factors to specific areas of embryoid bodies, aggregates of differentiating stem cells. The localized delivery technique provides spatial control of cell differentiation within the cultures, potentially enabling the creation of complex three-dimensional tissues. The local control also dramatically reduces the amount of growth factor required, an important cost consideration for manufacturing stem cells for therapeutic applications.

The microparticle technique, which was demonstrated in pluripotent mouse embryonic cells, also offers better control over the kinetics of cell differentiation by delivering molecules that can either promote or inhibit the process. Based on research sponsored by the National Institutes of Health and the National Science Foundation, the developments were reported online July 1 in the journal Biomaterials and were presented at the 11th Annual International Society for Stem Cell Research meeting held in Boston June 12-15, 2013.

"By trapping these growth factors within microparticle materials first, we are concentrating the signal they provide to the stem cells," said Todd McDevitt, an associate professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. "We can then put the microparticle materials physically inside the multicellular aggregate system that we use for differentiation of the stem cells. We have good evidence that this technique can work, and that we can use it to provide advantages in several different areas."

The differentiation of stem cells is largely controlled by external cues, including morphogenic growth factors, in the three-dimensional environment that surrounds the cells. Most stem cell researchers currently deliver the growth factors into liquid solutions surrounding the stem cell cultures with a goal of creating homogenous cultures of cells. Delivering the growth factors from microparticles, however, provides better control of the spatial and temporal presentation of the molecules that govern the growth and differentiation of the stem cells, potentially allowing formation of heterogeneous structures formed from different cells.

Groups of stem cells stick together as they develop, forming multicellular aggregates that form spheroids as they grow. The researchers took advantage of that by driving microparticles containing growth factor BMP4 or noggin which inhibits BMP4 signaling into layers of stem cells using centrifugation. When the cell aggregates formed, the microparticles became trapped inside.

The researchers used confocal imaging and flow cytometry to observe the differentiation process and found that growth factors in the microparticles directed the cells toward mesoderm and ectoderm tissues just as they do in solution-based techniques. But because the BMP4 and noggin molecules were directly in contact with the cells, much less growth factor was needed to spur the differentiation approximately 12 times less than what would be required by conventional solution-based techniques.

"One of the major advantages, in a practical sense, is that we are using much less growth factor," said McDevitt, who is also director of the Stem Cell Engineering Center at Georgia Tech. "From a bioprocessing standpoint, a lot of the cost involved in making stem cell products is related to the cost of the molecules that must be added to make the stem cells differentiate."

Beyond more focused signaling, the microparticles also provided a localized control not available through any other technique. That allowed the researchers to create spatial differences in the aggregates a possible first step toward forming more complex structures with different tissue types such as vasculature and stromal cells.

FDA bans stem cells from animals, plants

MANILA, Philippines - Stem cells taken from animals and plant derivatives are not allowed in the country, according to a circular of the Food and Drug Administration (FDA).

In FDA Circular 2013-017, FDA acting director Kenneth Hartigan-Go said stem cells harvested from human embryos for research purposes, human embryonic stem cells and their derivatives as well as aborted human fetal stem cells and their derivatives are also not authorized.

Go said such stem cells are prohibited from creation, importation, promotion, marketing and use.

This means that selling and manufacturing of soap and other products that supposedly contain stem cells from placenta and animals, which have been flooding the market recently, are also prohibited.

The FDA circular said imported human stem cell-based products are allowed, provided they are not hand-carried and meet other requirements.

The FDA requires the use of appropriate mode of transportation and storage in transporting allogeneic stem cells or those derived from other humans and not the patient himself.

Under the guidelines previously issued by the Department of Health (DOH), only autologous stem cells, or those taken from the patients themselves, are acceptable.

In Circular 2013-012 issued last May 15, the FDA had also warned the public against receiving unapproved stem cell preparations in non-health facilities.

The agency said unapproved stem cell preparations and therapy without prior FDA-DOH approval could cause infectious diseases and severe complications which may lead to permanent disabilities, physical deformities, autoimmune diseases and even death, without the benefit of health insurance coverage.

Calimmune Initiates HIV Stem Cell Study at Two California Research Sites

LOS ANGELES--(BUSINESS WIRE)--

The HIV gene medicines company Calimmune announced today that the first patient has begun treatment in a Phase I/II clinical trial designed to determine whether a pioneering genetic medicine approach can help to protect individuals infected with HIV from the effects of the virus. The study, Safety Study of a Dual Anti-HIV Gene Transfer Construct to Treat HIV-1 Infection, utilizes a gene medicine called Cal-1, developed in the lab of Nobel Laureate Dr. David Baltimore and by Calimmune.

In the study, 12 HIV-positive participants will be infused with their own T cells and stem cells (hematopoietic stem cells, HSC), which have been modified to block the HIV receptor CCR5, and to prevent HIV fusion. The procedure is designed to prevent the virus from entering and damaging protected cells. The dual approach used in the study is designed to reduce the possibility that HIV can develop resistance to the procedure.

The goal of the study is to assess the safety, feasibility and tolerability of Cal-1 in HIV-infected individuals who have previously been on highly active antiretroviral therapy (HAART) but are not currently taking any antiretroviral agent. In addition to routine clinical and laboratory assessments to monitor general health and HIV infection, the study will monitor the presence of Cal-1 protected cells in various cell types in the blood and lymphoid tissue. Other analyses will monitor the safety of Cal-1. The first patient was treated in the study in late June. Data from this study are expected in 2015.

All participants in the studys three arms will receive the Cal-1 gene transfer. Participants in two of the three study arms will also receive different doses of a preconditioning drug known as busulfan, which may make the therapy more effective.

This study is an early but important step in an emerging area of scientific exploration, representing the culmination of more than a decade of research and development, said Calimmune Chief Executive Officer Louis Breton. We are optimistic that what we learn from this study may bring us closer to the day when a one-time treatment could provide an alternative to a lifetime of antiretroviral therapy.

The study has been partially funded by the California Institute for Regenerative Medicine (CIRM). The study will take place at clinical trial sites in Los Angeles and San Francisco, Calif., under the direction of Principal Investigators Ron Mitsayasu, M.D., of UCLA and Jacob P. Lalezari, M.D., of Quest Clinical Research.
