UTHealth Uses $1.9 Million Grant to Study Therapy for Autoimmunity

Posted: April 18, 2012 at 2:13 pm

Newswise HOUSTON (April 16, 2012) A researcher at The University of Texas Health Science Center at Houston (UTHealth) is studying a novel cell therapy that could help avoid autoimmune problems after stem cell transplantation, as well as potentially treat other autoimmune diseases.

The preclinical study, funded with a $1.9 million grant from the National Institutes of Health (NIH) National Heart, Lung, and Blood Institute (NHLBI), is being conducted in collaboration with the NIH and The University of Texas MD Anderson Cancer Center.

The therapy centers on regulatory T cells, which are central to the control of autoimmunity in the body. Dat Tran, M.D., assistant professor in the Pediatric Research Center at the UTHealth Medical School, said the therapy could help prevent graft-versus-host disease (GVHD), an autoimmune disorder that occurs in up to 80 percent of cancer patients receiving bone marrow stem cell transplants. It could also potentially treat other autoimmune diseases such as type 1 diabetes.

Leukemia and lymphoma are blood cell cancers, immune system cancers. You have to wipe out the whole immune system and then give the person a new system through a stem cell transplant, said Tran, who holds a dual appointment in the UTHealth Department of Pediatrics Division of Allergy, Immunology and Rheumatology. But the immune system is designed to detect foreign particles and attack them. Depending on how close the match is, you can have a reaction between the graft donor and the host patient that results in an autoimmunity problem.

According to the National Institutes of Health, GVHD occurs in 30 to 40 percent of recipients using related donors and 60 to 80 percent in recipients using unrelated donors. Acute symptoms include abdominal pain, diarrhea, fever, jaundice, skin rash, vomiting and weight loss. Chronic symptoms include dry eyes and mouth, hair loss, hepatitis, lung and digestive tract disorders and skin thickening. Some cases can lead to death.

The most effective treatments are high-dose corticosteroids, which often have severe side effects. Thats not good enough, Tran said.

While working at the National Institutes of Health as an allergy and immunology fellow, Tran began to research ways to enhance the regulatory T cells in the body.

Regulatory T cells are extremely important because if you dont have them, your body will develop autoimmunity and attack itself, he said. We think perhaps the regulatory T cells dont develop fast enough in stem cell transplants. So I thought, Why dont we put the regulatory T cells in the body before the transplant to enhance transplantation and avoid autoimmunity?

The challenge, he said, was finding a way to grow the T cells in large enough quantities and separate out the best ones to achieve a more potent population. He found a marker they could use to isolate the good regulatory T cells and published a proof-of-theory paper in the May 2009 issue of the American Hematology Society journal Blood.

Were now testing the cells in mice to see if they are stable and potent and that they will work, he said. In the next five years, in collaboration with MD Anderson, we hope we can prevent GVHD.

Depression drugs linked to falls in elderly

Posted: April 15, 2012 at 3:59 pm

by Mike Adams

Falls are the leading cause of accidental death in the elderly population of adults over 65 years of age. A recent study found that elderly people who suffer from dementia are more likely to suffer falls if they are given anti-depressants.

Selective serotonin uptake inhibitors (SSRIs) are frequently prescribed to dementia patients, who often also experience depression. The British Journal of Clinical Pharmacology reported that the risk of elderly injuring themselves from falls was TRIPLED after they were given SSRIs. This class of drugs includes the popular depression drugs Prozac and Paxil, which have long been considered first-line therapy for treatment of depression in older adults.

The high risk of falls following treatment with older anti-depressant medications is well established, as these drugs have long been shown to cause unpleasant and dangerous side effects in elderly such as dizziness and unsteadiness.

Although the medical industry and Big Pharma made claims that the newer SSRI-type anti-depressant drugs would likely reduce these dangerous consequences, the latest research from the Erasmus University Medical Center in Rotterdam appears to show the reverse. Read more...

Barry Callebaut investigates Acticoa for ageing, longevity

Posted: April 15, 2012 at 3:59 pm

Barry Callebaut is venturing down avenues of research that would allow it to market its Acticoa chocolate on an ant-ageing and longevity platform.

Dark chocolate has been much on the news lately thanks to research on the healthy potential of its high antioxidant content. Barry Callebaut has devised a process with which it says it can preserve more of the natural polyphenols than is possible through conventional methods.

So far chocolate produced using this process, called Acticoa, has been marketed mainly on the basis of its high polyphenol content and health benefits associated with polyphenols. But with positive results from a pre-clinical trial in which rats that suffered oxidative stress and were fed the chocolate were seen to live considerably longer than rats that received a placebo, the company is paving the way to market it to the burgeoning anti-ageing market.

CEO of Biotime’s Comments on Stem Cell Agency and Development of Therapies

Posted: April 15, 2012 at 3:58 pm


Michael West, CEO of Biotime, Inc.of Alameda, Ca., has published the text of his prepared remarks to the Institute of Medicine panel examining the performance of the $3 billion California stem cell agency.

Here is one excerpt from the statement by West, who was also CEO at Advanced Cell Technology and founded Geron.

"To put it simply, stem cell research by itself will not lead to cures. Research and DEVELOPMENT leads to cures. In my opinion, if CIRM fails to deliver on its goal to deliver cures, it will not be a result of internal governance issues. Instead, it will be a result of inefficient capital allocation. A graphic way of visualizing my point is to say that CIRM has historically funded primarily research, and little product development, i.e. large “R” little “d”. Approximately 5% of CIRM’s expenditures have been allocated to biotechnology and health science entities whose expertise is product development, and 95% has been allocated to nonprofit institutions in the state for basic research. Human therapeutic product development in the United States requires a very intense and expensive process for approval that is primarily focused on development side of the equation. In this respect, therapeutic approvals differ significantly from the discovery and development of silicon-based technologies that have been so successfully commercialized in California."

Here is a link to the full text of what West posted on the Biotime web site.

Correction: ACT Not Rejected 15 Times by California Stem Cell Agency

Posted: April 15, 2012 at 3:58 pm


A venture capitalist who said earlier this week that the California stem cell agency rejected 15 grant applications from Advanced Cell Technology this afternoon retracted the statement, which he said was incorrect.

Gregory Bonfiglio, managing partner in Proteus Regenerative Medicine, said in an email,

"Although I believed that number to be true at the time I stated it, I have now determined that the number of CIRM grant applications ACT filed as the principal investigator was substantially below 15."

Bonfiglio made the assertion Tuesday at a meeting of the Institute of Medicine panel looking into the performance of the $3 billion California stem cell agency, which has been criticized for its lack of funding of biotech firms.

Here is more of what Bonfiglio had to say in his email this afternoon,

"Unfortunately, your California Stem Cell Report posting on April 11 contains some inaccurate information, for which I appear to have been the source.  As you will recall, I stated during the IOM Panel that Advanced Cell Technology had submitted multiple applications for funding from CIRM, but had been unsuccessful in obtaining any funding from CIRM.  I also stated that ACT had been involved in “15 grant applications” to CIRM.   You highlighted that number in your April 11 California Stem Cell Report posting.   Unfortunately, that number is not accurate.  Although I believed that number to be true at the time I stated it, I have now determined that the number of CIRM grant applications ACT filed as the Principal Investigator was substantially below 15.   The number I quoted in the IOM Meeting on April 10 included applications in which ACT had some involvement, but was not the lead principal Investigator.  ACT has filed several applications for CIRM funding as the lead PI, but the number of CIRM applications in which ACT was the lead PI was far below 15.   Moreover, some of ACT’s direct applications for CIRM funding were withdrawn by ACT, rather than denied by CIRM.

"I would request that you correct this inaccuracy regarding ACT's applications for CIRM funding as soon as possible.  I'm sure you will agree that the regenerative medicine community, and the general public, have a real and significant interest in obtaining accurate information about developments at CIRM, and that the publication of inaccurate information is a tremendous disservice to all involved.  More importantly, ACT is a publicly traded company and the publication of inaccurate information regarding ACT, its technologies, or its funding could have adverse consequences for the company.   Furthermore, as an active participant in the regenerative medicine community who has spent his professional career developing a reputation for honesty, accuracy, and integrity I am very concerned that I might be the source of inaccurate information regarding developments within the field of regenerative medicine.  For these reasons, I would ask that you retract the statement in your April 11 Blog posting that ACT was 'rejected 15 times for funding' by CIRM, and that you refrain from making any other statements to that effect.

"I appreciate your cooperation in this regard, and I would request that you move quickly to correct the inaccuracy in your April 11 Blog posting.   As I am sure you are aware, information in blog postings is sometimes picked up by more traditional media, and I would not want any republication of this inaccurate information regarding ACT’s grant applications to CIRM."

At the time Bonfiglio made his comments concerning ACT, top officials of the stem cell agency were in the room, but did not make any statement concerning his assertion. On the morning of April 11 prior to publication of the item, the California Stem Cell Report asked ACT for comment .

No response has been received from ACT about the figure. CIRM also has not commented since the item appeared.

California Stem Cell Agency Cited for Improvements in Transparency

Posted: April 15, 2012 at 3:58 pm


IRVINE, Ca. – The $3 billion California stem cell agency was praised this week for making progress in accountability and transparency during the last year.

The comments came from a representative of California state Controlller John Chiang, the state's top fiscal officer and who also chairs the only state entity specifically charged with financial oversight of the stem cell agency and its board.

Ruth Holton-Hodson, deputy state controller, told the blue-ribbon Institute of Medicine panel examining the performance of the stem cell agency that the controller's office "would like to acknowledge the progress the new leadership has made in the last year towards making CIRM a far more transparent and accountable agency than it has been in the past."

CIRM has a new chairman, J.T. Thomas, a Los Angeles financier, who has been in place since the beginning of last July. He succeeded Bob Klein, who was the initial agency chairman and who took office in 2004.

In her testimony at the IOM hearing here on Tuesday, Holton-Hodson discussed previous problems that CIRM had with the transparency of its budget. She said,

"We are very pleased that CIRM’s new leadership recognized this as a problem and quickly adopted a much more transparent budget format which is broken down by function. To make CIRM’s expenditures as transparent as possible, we have also recommended that they post the annual budget on the website. Again, we’re pleased to say that the new leadership has agreed to do this."

She also said,

"At our most recent meeting (of the Citizens Financial Accountability and Oversight Committee), we also recommended that CIRM post all of its private donations and they have agreed to do this."

Holton-Hodson criticized the dual executive arrangement at CIRM that is written into law by Proposition 71. She said,

"It is difficult to uphold the appearance of accountability and objectivity when the board chair has direct line authority over some CIRM staff positions. In essence under the current model, the chair is responsible for evaluating and approving some of the work of the chair.

"While this issue is still outstanding, it is important to acknowledge that the current leadership has made significant progress in more clearly delineating the responsibilities of the chair and the president."

California Stem Cell Agency Nixes ACT Grant Applications 15 Times

Posted: April 15, 2012 at 3:58 pm


(Editor's note: The assertion in this item that 15 applications by ACT were rejected by the California stem cell agency is incorrect, according to the venture capitalist who made the statement. He retracted it on the afternoon of April 12. His explanation can be found here. )


IRVINE, Ca. --The only firm in the nation conducting an ongoing hESC clinical trial has been rejected 15 times for funding by California's $3 billion stem cell agency.

The figure was reported yesterday at a hearing by the blue-ribbon Institute of Medicine panel looking into the performance of the stem cell agency, which has been sharply criticized in recent years for its paucity of industry funding.

Gregory Bonfiglio, managing partner in Proteus Regenerative Medicine, a stem cell venture capital firm in Portola Valley, Ca., disclosed the grant attempts by Advanced Cell Technology, whose nominal headquarters are in Santa Monica, Ca. Bonfiglio indicated that it was a high profile example of how CIRM is not taking the necessary steps to fulfill its goal of developing therapies that actually reach the clinic.

He noted that ACT received national attention in January when it posted favorable findings for its clinical trial at UCLA dealing with blindness but that the firm was still unable to win a CIRM grant over the last several years.

ACT had moved much of its operations to California in the wake of passage of Proposition 71, the measure that created the state's stem cell research effort in 2004. It has since re-centered its operations in Massachusetts.

The California Stem Cell Report has queried ACT on its grant efforts and will carry its response verbatim when it is received.

Another firm, which cannot be identified, said privately yesterday that it was rejected 14 times.

According to our calculations based on figures this morning on the CIRM web site, businesses have received only $54.3 million in grants and loans during the last seven years, 4 percent of the $1.3 billion awarded. However, the CIRM list slightly understates the industry total. At least two other firms are sharing in two $20 million grants involving academic institutions, but are not noted on the list.

Yesterday's IOM meeting was the second and final California public session for the CIRM inquiry. Most of the day was occupied by a variety of critiques of the organization. The panel has already heard extensively from the agency itself and beneficiaries of its grants. The IOM report is expected in November.

Harold Shapiro, chairman of the panel and former president of Princeton University, described yesterday afternoon's panel involving stem cell business executives as "one of the more interesting" of the day.

One of the speakers was Michael West, CEO of Biotime in Alameda, which has received $4.7 million from CIRM. West, the founder of Geron, was also head of ACT when it moved it to California. He said CIRM had several "blind spots," including misconceptions about how products are made. For example, West said, CIRM's performance indicates that it does not fully understand that development leads directly to cures -- not research.

West said that if the high tech industry had to rely on CIRM-type funding years ago, laptops and iPads would still be in the lab instead of the marketplace.

The business industry representatives said that creation of CIRM has been beneficial for stem cell  research, but cited a number of deficiencies in connection with industry applications.

In some ways, their comments echoed past remarks by several CIRM board members, who have expressed concern about the lack of funding for industry, as well as those of the agency's own external review panel. One issue raised by those CIRM directors has been the lack of grant reviewers with product development and industry expertise.

At yesterday's hearing, Gabriel Nistor, vice president of research and development at California Stem Cell in Irvine, said, it is "exceedingly rare to find academics (grant reviewers) that understand the complexities" involving industry. Nistor said his firm has applied for a "few" CIRM grants. None have been awarded.

Also speaking was Allan Robins, CEO of Viacyte in San Diego, who said his firm has done well with CIRM funding. It has received $26.2 million, nearly all of it in the form of a loan. But he said companies develop products – not academia.

Center for Genetics and Society: ‘Wrong’ to Ask for More Billions for Stem Cell Agency

Posted: April 15, 2012 at 3:58 pm


IRVINE, Ca. – The Center for Genetics and Society today said it would "wrong" to ask the people of California for more money to continue financing stem cell research at state expense.

Marcy Darnovsky, associate executive director of the Berkeley, Ca., non-profit group, addressed a blue-ribbon Institute of Medicine panel evaluating the performance of the $3 billion California stem cell agency, which is financed by money borrowed by the state. The agency is expected to run out of cash in about five years.

Darnovsky said,

"In structural terms, a key question now is what will happen after CIRM’s public funding is exhausted. According to CIRM’s transition plan, another bond measure for additional public funding 'would be premature at this time,' but is still on the table. In our view, any additional public monies for CIRM would have to be justified in an analysis that emphasized health care priorities and health care disparities. While there is always tension between the allocation of public funds to scientific research and to other public goods, given our state’s economic decline and budgetary crisis, with so many critical social programs being gutted, we believe it would be simply wrong to ask Californians to set aside more money for one avenue of research, however important."

Representatives of the stem cell agency were present at today's hearing on the UC Irvine campus, but did not speak publicly at today's session. CIRM officials, however, have testified before the panel on two other days of public hearings. The agency is paying the IOM $700,000 to conduct the study. Its results and recommendations are expected to be published in November.

Darnovsky and others testifying at the morning session were critical of the agency's lack of accountability, built-in conflicts of interest and immunity from normal government oversight (see here and here).

Darnovsky said, "

The requirement for 70% super-majorities (to change the law regarding CIRM) means that there is still no meaningful oversight of CIRM by elected officials. The ICOC is still tainted by its built-in conflicts of interest. It still includes no representation of the public beyond disease advocates. Members of CIRM’s powerful Working Groups, including the one that reviews grant applications, are still not required to publicly disclose their individual financial interests.

"Given that hundreds of millions of dollars remain to be disbursed, and the widely mooted possibility that CIRM will develop a role that continues beyond the public funding stream that was allocated in 2004, now is the time to clarify and address these issues."

Here is the full text of Darnovsky's comments.

The Search for Stem Cell Cures: Can California’s $3 Billion Agency Move Audaciously?

Posted: April 15, 2012 at 3:58 pm


IRVINE, Ca.-- California's unprecedented stem cell research effort faces a tight timetable for making major progress in fulfilling promises to voters seven years ago, complicated by potential conflicts of interest, a blue-ribbon panel was told this morning.

David Jensen, editor of the California Stem Cell Report, made the comments to the Institute of Medicine panel looking into the performance of the $3 billion California Institute of Regenerative Medicine.

The panel's inquiry comes as the agency is re-evaluating its strategies as it faces loss of funding in about 2017.

Here is the full text of Jensen's statement.
