Americans flocking to India for stem cell therapy

Posted: May 29, 2012 at 12:11 am

Washington: A growing number of Americans are travelling to India to seek treatment for rare diseases through India's experimental embryonic stem cell therapy, according to an investigative report.

Among them Cash Burnaman, a 6-year-old South Carolina boy, who travelled with his parents to India seeking treatment for a rare genetic condition that has left him developmentally disabled, CNN reported.

"Cash is mute. He walks with the aid of braces. To battle his incurable condition, which is so rare it doesn't have a name, Cash has had to take an artificial growth hormone for most of his life," it said.

A growing number of Americans are travelling to India to seek treatment for rare diseases through experimental embryonic stem cell therapy.

His divorced parents, Josh Burnaman and Stephanie Krolick, have paid tens of thousands of dollars to have Cash undergo experimental injections of human embryonic stem cells at New Delhi's NuTech Mediworld run by Dr Geeta Shroff, a retired obstetrician and self-taught embryonic stem cell practitioner.

Shroff first treated Cash -- who presents symptoms similar to Down Syndrome -- in 2010. "I am helping improve their quality of life," she told CNN.

After five weeks of treatment, Cash and his parents returned home to the US. That's when Cash began walking with the aid of braces for the first time.

For four or five weeks of treatment, Shroff says she has charged her 87 American patients an average of $25,000.

But doctors cited by CNN said all that work and hope and money Cash's supporters have funnelled into his experimental therapy likely will have no medical benefits.

"There is zero evidence for what she (Shroff ) is doing being effective," Rutgers University's Dr Wise Young, a leading US neuroscientist, was quoted as saying.

Makati Medical Center now offering stem cell therapy

Posted: May 29, 2012 at 12:11 am

THE MAKATI Medical Centers Cancer Center celebrated its first year anniversary and marked the occasion with the launch of its Cellular Therapeutics Laboratory. Present at the ribbon-cutting ceremony were Dr. Eric Flores, head, Spine Clinic and Stem Cell Lab; Rosalie Montenegro, Makati Medical Center president and CEO; Dr. ManuelO. Fernandez Jr., executive vice president and director, Professional Services; Dr. Remedios G. Suntay, director and treasurer, MDI Board; Dr. Benjamin N. Alimurung, medical director; Dr. Francis Chung, scientific officer, Stem Cell Lab; and Augusto P. Palisoc Jr., executive director, president and CEO, MPIC Hospital Group.

MAKATIMEDS Cellular Therapeutics Laboratory is managed by experienced scientists with extensive training and is affiliated with the International Society for Cellular Therapy.

Stem cell therapy is now being offered at Makati Medical Center (MMC) as potential cure for a wide range of illnesses, from various types of cancer and heart ailments to incurable diseases such as multiple sclerosis, Parkinsons and Alzheimers.

Stem cell therapy is believed to be effective in bone marrow transplant for leukemia patients, and with early intervention, yields desirable results among renal and prostate cancer patients.

Launched in the first year anniversary of the hospitals cancer center, MMCs Cellular Therapeutics Laboratory is equipped with technology touted to be totally unmatched in our country, says Dr. Francis Chung, scientific officer of the lab. No system exists elsewhere.

Employing the strictest sterility standards at par with that of the US Food and Drug Administration, the lab has state-of-the-art facilities. The Clinimacs CD34 Reagent System is a machine that isolates specific cells needed for the procedure, while the Flow Cytomer ensures the purity of cultured cells.

Transplantation

Sourcing the stem cells, however, is what truly sets the Philippines premier health institution apart from chi-chi spas that also push stem cell therapy for beauty and anti-aging procedures.

At MMC, healthy stem cells are acquired from the patients themselves, a process known as autologous transplantation. For those suffering from an ailment, a parent, sibling or other close relative could be the donor. The hospital strives for utmost compatibility between patient and donor through a 10-point DNA matching system.

If a battery of tests finds a patient to be up to it, medication is given to prepare him for stem cell harvest.

Di’Anno Wants Former Iron Maiden Bandmate To Undergo Stem Cell Therapy Recap

Posted: May 27, 2012 at 2:13 pm

Burr, the drummer with Maiden from 1979 until 1982, has been in a wheelchair as a result of multiple sclerosis, which has been attacking his nervous system since before he was diagnosed in 2002.

MS reduces the ability of the brain and spinal cord to communicate with each other, resulting in a wide range of potentially severe symptoms. The cause is unknown and there is no cure; but in 2009 researchers made the first breakthrough in reversing symptoms through stem cell therapy.

Di'Anno tells Talking Metal Pirate Radio Burr's condition is "not very good at all." - He had a lot to say, read it here.

UCI stem cell researcher to receive $4.8 million in state funding

Posted: May 25, 2012 at 8:13 pm

Public release date: 24-May-2012 [ | E-mail | Share ]

Contact: Tom Vasich tmvasich@uci.edu 949-824-6455 University of California - Irvine

Irvine, Calif., May 24, 2012 A UC Irvine immunologist will receive $4.8 million to create a new line of neural stem cells that can be used to treat multiple sclerosis.

The California Institute for Regenerative Medicine awarded the grant Thursday, May 24, to Thomas Lane of the Sue & Bill Gross Stem Cell Research Center at UCI to support early-stage translational research.

CIRM's governing board gave 21 such grants worth $69 million to 11 institutions statewide. The funded projects are considered critical to the institute's mission of translating basic stem cell discoveries into clinical cures. They are expected to either result in candidate drugs or cell therapies or make significant strides toward such treatments, which can then be developed for submission to the Food & Drug Administration for clinical trial.

Lane's grant brings total CIRM funding for UCI to $76.65 million.

"I am delighted that CIRM has chosen to support our efforts to advance a novel stem cell-based therapy for multiple sclerosis," said Peter Donovan, director of the Sue & Bill Gross Stem Cell Research Center.

MS is a disease of the central nervous system caused by inflammation and loss of myelin, a fatty tissue that insulates and protects nerve cells. Current treatments are often unable to stop the progression of neurologic disability most likely due to irreversible nerve destruction resulting from myelin deficiencies. The limited ability of the body to repair damaged nerve tissue highlights a critically important and unmet need for MS patients.

In addressing this issue, Lane who also directs UCI's Multiple Sclerosis Research Center will target a stem cell treatment that will not only halt ongoing myelin loss but also encourage the growth of new myelin that can mend damaged nerves.

"Our preliminary data are very promising and suggest that this goal is possible," said Lane, a Chancellor's Fellow and professor of molecular biology & biochemistry. "Research efforts will concentrate on refining techniques for production and rigorous quality control of transplantable cells generated from high-quality human pluripotent stem cell lines, leading to the development of the most therapeutically beneficial cell type for eventual use in patients with MS."

State awards stem cell grants to medical researchers

Posted: May 25, 2012 at 8:13 pm

SACRAMENTO California's stem cell agency today approved two grants to UC Davis Health System researchers for their innovative work in regenerative medicine.

Kyriacos A. Athanasiou, distinguished professor of orthopaedic surgery and professor and chair of biomedical engineering, and the Child Family Professor of Engineering at UC Davis, is investigating the use of skin-derived stem cells to heal cartilage injuries and debilitating conditions of the knee such as osteoarthritis.

W. Douglas Boyd, professor of surgery, plans to further refine a novel approach to treating cardiovascular injuries suffered during a heart attack by using stem cells and a tissue-like scaffold to repair cardiac damage.

The pair received individual grants totaling approximately $6.6 million from the California Institute for Regenerative Medicine's (CIRM) governing board.

Athanasiou's and Boyd's multi-year grants were among the proposals submitted to CIRM for its third round of Early Translational Awards, which are intended to enable clinical therapies to be developed more rapidly.

"Both of these scientists are conducting exciting research that could have far-reaching implications in health care," said Jan Nolta, director of the UC Davis Institute for Regenerative Cures and the university's stem cell program director. "Dr. Athanasiou is bioengineering new cartilage that could have the same physiological integrity as the cartilage a person is born with. Dr. Boyd is developing a treatment that uses a paper-thin patch embedded with stem cells to harness their regenerative powers to repair damaged heart muscle."

Boyd, who's a pioneering cardiothoracic surgeon, pointed out in his CIRM proposal that heart disease is the nation's number-one cause of death and disability. An estimated 16.3 million Americans over the age of 20 suffer from coronary heart disease, which in 2007 accounted for an estimated 1 in 6 deaths in the U.S. Boyd plans to use bone-marrow derived stem cells -- known as mesenchymal stem cells -- in combination with a bioengineered framework known as an extracellular matrix, to regenerate damaged heart tissue, block heart disease and restore cardiac function, something currently not possible except in cases of a complete and very invasive heart transplant.

An expert in biomedical engineering, Athanasiou is focusing on developing a cellular therapy using stem cells created from an individual's own skin -- known as autologous skin-derived stem cells -- which have shown great promise in animal models. He plans to use the new funding to conduct extensive toxicology and durability tests to determine the technique's long-term safety and efficacy. Such tests are among the many steps needed to advance toward human clinical trials.

Cartilage is the slippery tissue that covers the ends of bones in joints, allowing bones to glide over each other and absorbing the shock of movement. Cartilage defects from injuries and lifelong wear and tear can eventually degenerate into osteoarthritis. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, osteoarthritis is the most common form of arthritis and affects an estimated 27 million Americans over the age of 25.

"For anyone suffering from osteoarthritis or other debilitating cartilage conditions, Dr. Athanasiou's goal of using stem cells to regenerate new tissue could have enormous quality-of-life and economic benefits," said Nolta, who is the recipient of a prior translational grant from CIRM to develop potential therapies for Huntington's disease . "Dr. Boyd's work is equally promising because he's using a bioengineered structure to encourage cardiac tissue repair, which could have important benefits in the treatment of heart disease."

Chronic Pain Is Relieved by Cell Transplantation in Lab Study

Posted: May 23, 2012 at 8:11 pm

UCSF Scientists Aim to Use Embryonic Stem Cells for Treatment

Newswise Chronic pain, by definition, is difficult to manage, but a new study by UCSF scientists shows how a cell therapy might one day be used not only to quell some common types of persistent and difficult-to-treat pain, but also to cure the conditions that give rise to them.

The researchers, working with mice, focused on treating chronic pain that arises from nerve injury -- so-called neuropathic pain.

In their study, published in the May 24, 2012 issue of Neuron, the scientists transplanted immature embryonic nerve cells that arise in the brain during development and used them to make up for a loss of function of specific neurons in the spinal cord that normally dampen pain signals.

A small fraction of the transplanted cells survived and matured into functioning neurons. The cells integrated into the nerve circuitry of the spinal cord, forming synapses and signaling pathways with neighboring neurons.

As a result, pain hypersensitivity associated with nerve injury was almost completely eliminated, the researchers found, without evidence of movement disturbances that are common side effects of the currently favored drug treatment.

Now we are working toward the possibility of potential treatments that might eliminate the source of neuropathic pain, and that may be much more effective than drugs that aim only to treat symptomatically the pain that results from chronic, painful conditions, said the senior author of the study, Allan Basbaum, PhD, chair of the Department of Anatomy at UCSF.

Although pain and hypersensitivity after injury usually resolve, in some cases they outlast the injury, creating the condition of chronic pain. Many types of chronic pain are induced by stimuli that are essentially harmless such as light touch but that are perceived as painful, according to Basbaum.

Chronic pain due to this type of hypersensitivity is often a debilitating medical condition. Many people suffer from chronic neuropathic pain after a bout of shingles, years or decades after the virus that causes chicken pox has been vanquished. Chronic pain is not merely prolonged acute pain, Basbaum said.

Those who suffer from chronic pain often get little relief, even from powerful narcotic painkillers, according to Basbaum. Gabapentin, an anticonvulsant first used to treat epilepsy, now is regarded as the most effective treatment for neuropathic pain. However, it is effective for only roughly 30 percent of patients, and even in those people it only provides about 30 percent relief of the pain, he said.

4.5 (2 votes)

Prochymal (remestemcel-L) is also the first drug to be approved for the treatment of acute graft-vs-host disease (GvHD) in children, a devastating complication of bone marrow transplantation that kills almost 80% of all affected children, many of which just weeks after they have been diagnosed.

GvHD is the leading cause of transplant-related mortality, caused by an immunologic attack. Severe GvHD can cause blistering of the skin, intestinal hemorrhage and liver failure and is extremely painful with a death rate of up to 80%. At present, the first-line standard therapies for GvHD are steroids. Given that the success rate of steroids is only 30 to 50%, the only other therapy if steroids fail is limited to immunosuppressive agents that are used off-label with little benefit and significant toxicities. Until the approval of Prochymal, there has not been any other therapy for GvHD.

Osiris Therapeutics Inc. was awarded authorization for Prochymal under Health Canada's Notice of Compliance with conditions (NOC/c). A NOC/c is an authorization to market a drug with the condition that the manufacturer undertakes additional studies to verify the clinical benefit. This pathway provides access to treatments for unmet medical conditions and has demonstrated its benefits outweigh its risks in clinical trials.

Andrew Daly, M.D., Clinical Associate Professor from the Department of Medicine and Oncology at the University of Calgary, Canada and leading researcher of Prochymal's phase 3 clinical program declared:

C. Randal Mills, Ph.D., President and Chief Executive Officer of Osiris announced:

Prochymal is an intravenous formulation of mesenchymal stem cells (MSCs), which are derived from the bone marrow of healthy adult donors aged between 18 and 30 years. The MSCs are selected from the bone marrow and grown in culture, producing up to 10,000 doses of Prochymal from a single donor. The drug is a true off-the-shelf stem cell product, which is stored frozen until it is needed. Prochymal is infused through a simple intravenous line without the need to type or immunosuppress the recipient. The drug is currently undergoing Phase 3 trials for refractory Crohn's disease, as well as undergoing clinical trials for the treatment of heart attacks and type-1 diabetes.

Health Canada granted the Prochymal's authorization for the management of acute GvHD in children who are unresponsive to steroids, based on the drug's results of clinical trials. Prochymal was recommended by an independent expert advisory panel, which was commissioned to assess the drugs safety and efficacy.

Indian clinic's stem cell therapy real?

STORY HIGHLIGHTS

For more of CNN correspondent Drew Griffin's investigation of India's experimental embryonic stem cell therapy, watch "CNN Presents: Selling a Miracle," at 8 and 11 p.m. ET Sunday on CNN.

New Delhi (CNN) -- Cash Burnaman, a 6-year-old South Carolina boy, has traveled with his parents to India seeking treatment for a rare genetic condition that has left him developmentally disabled. You might think this was a hopeful mission until you learn that an overwhelming number of medical experts insist the treatment will have zero effect.

Cash is mute. He walks with the aid of braces. To battle his incurable condition, which is so rare it doesn't have a name, Cash has had to take an artificial growth hormone for most of his life.

His divorced parents, Josh Burnaman and Stephanie Krolick, are so driven by their hope and desperation to help Cash they've journeyed to the other side of the globe and paid tens of thousands of dollars to have Cash undergo experimental injections of human embryonic stem cells.

The family is among a growing number of Americans seeking the treatment in India -- some at a clinic in the heart of New Delhi called NuTech Mediworld run by Dr. Geeta Shroff, a retired obstetrician and self-taught embryonic stem cell practitioner.

Shroff first treated Cash -- who presents symptoms similar to Down Syndrome -- in 2010. "I am helping improve their quality of life," Shroff told CNN.

After five weeks of treatment, Cash and his parents returned home to the U.S.

That's when Cash began walking with the aid of braces for the first time.

Osiris Wins Canadian Approval for First Stem-Cell Therapy

Posted: May 18, 2012 at 12:13 am

Osiris Therapeutics Inc. (OSIR) said it won the worlds first approval for a stem-cell drug, gaining clearance in Canada to sell Prochymal for a disease that can attack patients who received bone-marrow transplants.

Prochymal was approved for the treatment of acute graft versus host disease in children for whom steroids havent worked, the Columbia, Maryland-based company said today in a statement. Steroids have a 30 percent to 50 percent success rate, and severe GvHD can be fatal in 80 percent of cases, according to the company.

The therapy uses mesenchymal stem cells derived from bone marrow that can take on different forms, to combat the immune reaction that causes patients to literally peel out of their skin and shed their intestinal lining, Osiris Chief Executive Officer Randal Mills said in a telephone interview. The disease has no equal.

The company hasnt sought approval for this indication in the U.S., where regulators asked for more data before considering whether to allow sales of the drug, Mills said. Prochymal already is used in eight countries, including the U.S., on an expanded-access program basis, which allows patients to receive experimental medicines without participating in clinical trials.

This is the first regulatory approval of a stem-cell drug -- where the active ingredient of the drug is a stem cell -- in the world, Mills said. Its a huge deal for us and a huge deal for the entire field of stem-cell therapy.

Osiris fell less than 1 percent to $5.26 at the close of trading in New York. The shares have declined from an all-time high of $28.56 in 2007 as Osiris faced clinical setbacks, including two studies in 2009 that failed to show statistical improvement of Prochymal versus placebo.

The Canadian approval was based on data showing a clinically meaningful response 28 days after starting therapy for 61 percent to 64 percent of patients treated, Osiris said in the statement.

Prochymal may draw $16.7 million in revenue next year with Canadian approval, estimated Edward Tenthoff, an analyst with Piper Jaffray & Co. He said that while Prochymal, if successful in Canada, would be the first stem-cell drug to receive approval, other regenerative products used for wound-healing that employ stem cells are already on the market, such as Carticel from Sanofis Genzyme unit. That treatment uses a patients own cells to repair cartilage injuries in the knee, and is implanted with surgery, whereas Prochymal is an intravenous, off-the-shelf therapy. The stem cells are derived from bone marrow donations from healthy donors.

Progress in stem-cell research has been halting. Geron Corp. (GERN), based in Menlo Park, California, started the first U.S.- approved trial of human embryonic stem cells before ending the program last year because of research costs and regulatory complexities.

Scientists Discover Marker to Identify, Attack Breast Cancer Stem Cells

Posted: May 17, 2012 at 8:13 am

Cell surface protein blows potent cells cover; targeted drug works in preclinical tests

Newswise HOUSTON Breast cancer stem cells wear a cell surface protein that is part nametag and part bulls eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug, researchers at The University of Texas MD Anderson Cancer Center report online in Journal of Clinical Investigation.

Weve discovered a single marker for breast cancer stem cells and also found that its targetable with a small molecule drug that inhibits an enzyme crucial to its synthesis, said co-senior author Michael Andreeff, M.D., Ph.D., professor in MD Andersons Departments of Leukemia and Stem Cell Transplantation and Cellular Therapy.

Andreeff and colleagues are refining the drug as a potential targeted therapy for breast cancer stem cells, which are thought to be crucial to therapy resistance, disease progression and spread to other organs.

Its been difficult to identify cancer stem cells in solid tumors, Andreeff said. And nobody has managed to target these cells very well.

The marker is the cell surface protein ganglioside GD2. The drug is triptolide, an experimental drug that Andreeff has used in preclinical leukemia research. The team found triptolide blocks expression of GD3 synthase, which is essential to GD2production.

Triptolide stymied cancer growth in cell line experiments and resulted in smaller tumors and prolonged survival in mouse experiments. Drug development for human trials probably will take several years.

Cancer stem cells are similar to normal stem cells

Research in several types of cancer has shown cancer stem cells are a small subpopulation of cancer cells that are capable of long-term self-renewal and generation of new tumors. More recent research shows they resist treatment and promote metastasis.

Cancer stem cells are similar to normal stem cells that renew specialized tissues. The breast cancer findings grew out of Andreeffs long-term research in mesenchymal stem cells, which can divide into one copy of themselves and one differentiated copy of a bone, muscle, fat or cartilage cell.
