Stem cell gene therapy for sickle cell disease advances toward clinical trials

Posted: July 3, 2013 at 1:44 am

July 1, 2013 Researchers at UCLA's Eli & Edythe Broad Center of Regenerative Medicine & Stem Cell Research have successfully established the foundation for using hematopoietic (blood-producing) stem cells (HSC) from the bone marrow of patients with sickle cell disease (SCD) to treat the disease. The study was led by Dr. Donald Kohn, professor of pediatrics and microbiology, immunology and molecular genetics in the life sciences.

Kohn introduced an anti-sickling gene into the HSC to capitalize on the self-renewing potential of stem cells and create a continual source of healthy red blood cells that do not sickle. The breakthrough gene therapy technique for sickle cell disease is scheduled to begin clinical trials by early 2014. The study was published online in the Journal of Clinical Investigation.

Gene Therapy

Kohn's gene therapy approach using HSC from patient's own blood is a revolutionary alternative to current SCD treatments as it creates a self-renewing normal blood cell by inserting a gene that has anti-sickling properties into HSC. This approach also does not rely on the identification of a matched donor, thus avoiding the risk of rejection of donor cells. The anti-sickling HSC will be transplanted back into the patient's bone marrow and multiplies the corrected cells that make red blood cells without sickling.

"The results demonstrate that our technique of lentiviral transduction is capable of efficient transfer and consistent expression of an effective anti-sickling beta-globin gene in human SCD bone marrow progenitor cells, which improved the physiologic parameters of the resulting red blood cells." Kohn said.

Kohn and colleagues found that in the laboratory the HSC produced new non-sickled blood cells at a rate sufficient for significant clinical improvement for patients. The new blood cells survive longer than sickled cells, which could also improve treatment outcomes. The success of this technique will allow Kohn to begin clinical trials in patients with SCD by early next year.

Sickle Cell Disease

Affecting more than 90,000 patients in the US, SCD mostly affects people of Sub-Saharan African descent. It is caused by an inherited mutation in the beta-globin gene that makes red blood cells change from their normal shape, which is round and pliable (like a plastic bag filled with corn oil), into a rigid sickle-shaped cell (like a corn flake). Normal red blood cells are able to pass easily through the tiniest blood vessels, called capillaries, carrying oxygen to organs such as the lungs, liver and kidneys. But due to their rigid structure, sickled blood cells get stuck in the capillaries and deprive the organs of oxygen, which causes organ dysfunction and failure.

Current treatments include transplanting patients with donor HSC, which is a potential cure for SCD, but due to the serious risks of rejection, only a small number of patients have undergone this procedure and it is usually restricted to children with severe symptoms.

Stem-cell gene therapy for sickle-cell disease advances

Posted: July 2, 2013 at 6:48 am

Researchers at UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have successfully established the foundation for using hematopoietic (blood-producing) stem cells from the bone marrow of patients with sickle cell disease to treat the disease. The study was led by Dr. Donald Kohn, professor of pediatrics and of microbiology, immunology and molecular genetics.

Sickle cell disease causes the body to produce red blood cells that are formed like the crescent-shaped blade of a sickle, which hinders blood flow in the blood vessels and deprives the body's organs of oxygen.

Kohn introduced an anti-sickling gene into the hematopoietic stem cells to capitalize on the self-renewing potential of stem cells and create a continual source of healthy red blood cells that do not sickle. The breakthrough gene therapy technique for sickle cell disease is scheduled to begin clinical trials by early 2014. The study was published online today ahead of press in the Journal of Clinical Investigation.

Kohn's gene therapy approach, which uses hematopoietic stem cells from a patient's own blood, is a revolutionary alternative to current sickle cell disease treatments as it creates a self-renewing normal blood cell by inserting a gene that has anti-sickling properties into hematopoietic stem cells. This approach also does not rely on the identification of a matched donor, thus avoiding the risk of rejection of donor cells. The anti-sickling hematopoietic stem cells are transplanted back into the patient's bone marrow and multiply the corrected cells that make red blood cells without sickling.

"The results demonstrate that our technique of lentiviral transduction is capable of efficient transfer and consistent expression of an effective anti-sickling beta-globin gene in human sickle cell disease bone marrow progenitor cells, which improved the physiologic parameters of the resulting red blood cells," Kohn said.

Sickle cell disease mostly affects people of Sub-Saharan African descent, and more than 90,000 patients in the U.S. have been diagnosed. It is caused by an inherited mutation in the beta-globin gene that makes red blood cells change from their normal shape, which is round and pliable, into a rigid, sickle-shaped cell. Normal red blood cells are able to pass easily through the tiniest blood vessels, called capillaries, carrying oxygen to organs such as the lungs, liver and kidneys.

Current treatments include transplanting patients with donor hematopoietic stem cells, which is a potential cure for sickle cell disease, but due to the serious risks of rejection, only a small number of patients have undergone this procedure and it is usually restricted to children with severe symptoms.

This study was supported in part by a Disease Team I Award from the California Institute for Regenerative Medicine, the state's stem cell research agency, which was created by a voter initiative in 2004. The purpose of the disease team program is to support research focused on one particular disease that leads to the filing of an investigational new drug application with the FDA within four years. The program is designed to speed translational research - research that takes scientific discoveries from the laboratory to the patient bedside. This requires new levels of collaboration between basic laboratory scientists, medical clinicians, biotechnology experts and pharmacology experts, to name a few.

Other support came from UCLA's Broad Stem Cell Research Center and Jonsson Comprehensive Cancer Center, and from the Ruth L. Kirschstein National Research Service Award.

California Legislation, Human Egg Sales and Profits

Posted: July 1, 2013 at 10:56 am

California legislation to allow women
to be paid for their eggs for scientific research is sailing toward
final passage literally swaddled in motherhood and apple pie
arguments. Missing from the debate is a key reason behind
the bill – building profits for what some call the “baby
business.”

The legislation is touted as providing
equal treatment for women, permitting them to be paid for supplying
eggs for stem cell and other research, much as men are paid for
sperm. It also would put women who sell their eggs for research on an
equal economic footing with women who sell their eggs for fertility
treatments, which is currently permitted under state law. Payments to
those women range from an average of $9,000 to as much as $50,000,
according to a legislative analysis of the bill.

 Assemblywoman Susan Bonillla,
D-Concord, author of the bill(AB926), says,

“It is time to let women, just as any
other research subject, make an informed decision as to
participation, and justly compensate them for doing so.”

She also says that the ban on payments
has had serious impact on fertility research. In a legislative bill analysis, she says,

“It has led to a de facto prohibition
on women’s reproductive research in California, adversely
impacting the same women that the ban intended to protect. With few
oocytes donated, fertility research and fertility preservation
research has been at a standstill. This greatly affects women
suffering from fertility issues and women facing cancer who would
like to preserve their oocytes.”

Bonilla is carrying the measure on
behalf of an industry group, the American Society for Reproductive Medicine of Alabama. The fertility or baby business, which is largely
unregulated, brings in about $5 billion annually in the United
States from something like 500 clinics. It has grown rapidly over the
last couple of decades, but is likely heading for a soft spot.
Little public information is available
on the Internet discussing the industry's economic challenges.
However, demographic studies show that the size of the key market
for fertility services is stagnating. A 2012 report by the federal
government projects that the number of women in the 35 to 44 age
group, prime consumers of fertility services, is likely to grow only
0.5 percent from 2010 to 2020. And since that forecast was made, the
Census Bureau has downgraded its projections for total population
growth.
Bonilla's legislation effectively adds
a new, potential revenue stream for the industry. Fertility clinics
would be able to buy the eggs and then resell them to researchers,
adding premiums for eggs from women with special characteristics. The bill would also add a tool for bringing down the cost of fertility
treatments, which can run as much as $12,000 to $17,000 a round or
more and require several rounds, according to the NIH. Clinics could discount those prices for some women, bringing in
new customers, if they agree to authorize the use of excess eggs for
scientific research.
None of this appears necessarily
pernicious. What is pernicious is the absence of discussion of the
economics of the legislation. Without a full understanding of all
that is at stake, including economic issues and motivations,
legislators, the governor and the public are hard-pressed to make
good decisions about a significant change in California law.
Opponents of the legislation have
raised serious questions about the treatment of women by fertility
clinics, noting that the bill would turn egg providers into “vendors”
– not patients of the clinics. The Center for Genetics and Society
in Berkeley has captured the arguments in opposition including
testimony before a Senate committee hearing early in June.
Jennifer Schneider, a physician who
lost a 31-year-old daughter to cancer seven years after the younger
woman sold her eggs three times, told lawmakers,

“Unlike infertile women who are
considered patients, egg donors are treated as vendors( (her italics).
When they walk out of the IVF clinic, no one keeps track of them. 
My daughter’s death was not reported. The long-term risks of egg
donation are unknown."

Sindy Wei, a former egg provider and
now a physician with a Ph.D. in biology, testified that she wound up
in an intensive care unit after 60 eggs were extracted from her in
2001. She said,

“I fear that cases like mine are
buried deep by fertility centers concerned about their image. An
industry thriving on profits and reputation has little incentive to
report adverse events, or protect the health and medical rights of
donors.”

Where is the $3 billion California stem
cell agency on all this? The agency has not taken a position on the
bill nor have any major research organizations. The measure does not
change the law affecting agency-funded research, which bans the use of
compensation for eggs in its research. Enactment of the law, however, would
create a two-tier stem cell research standard in California, one for
scientists not constrained by the payment ban and another for those
who could use the full range of research tools. Some stem cell
researchers may well think that they have become disadvantaged as a
result.

(Editor's note: An earlier version of this article said the IVF business generated $4 billion in revenues annually. More recent estimates place it at $5 billion.)

FCT Controversy: MY STEM CELL THERAPY STORY

Posted: July 1, 2013 at 8:50 am

By: Jesus G. Dureza Posted: July 1, 2013 8:28 am

Over the last few days, Fresh Stem Cell Therapy (FCT) got into the headlines due to some controversy involving alleged deaths and complaints mentioning prominent names blaming stem cell treatment for their alleged negative effects.Naturally, just like any controversy, the stories unduly put under cloud this innovative and pioneering science of regenerative medicine that is reputed to treat illnesses, bring well being and rejuvenation.

MY FRIENDS The current news reports caught public attention and went viral. Many friends who were following Beths FCT experience and who were planning to also undergo FCT were calling. They were bothered by the reports. I was myself personally disturbed because all of them who were mentioned as having experienced negative results, I knew in person. Congressman ERICO AUMENTADO of Bohol and Camiguin Congressman LOLOY ROMUALDO both were my close friends and whom I worked with when I was with the government. And the controversy all the more struck me because I and my wife Beth saw and experienced for ourselves the positive NOT NEGATIVE results of FCT seven months after treatment at VILLA MEDICA in Germany.

Let me trace back. I knew Congressman Erico well even when he was still Bohol Governor. His successful efforts in clearing his province of armed insurgency gained national attention. When I was Malacanang Presidential Peace Adviser, I used the Bohol experience as example of a success story. So, when initial reports surfaced about FCT having caused his death, I sat up and took special attention. Later, his son came out publicly DENYING the story saying his father died of pneumonia and NOT due to FCT. He said his fathers lungs were already in serious condition but after getting a first infusion of FCT, his condition suddenly and dramatically improved and he was hitting the election campaign trail like superman. In fact they were preparing to again return to Germany for another infusion encouraged by its initial favorable results when death intervened and overtook events.

The other prominent name mentioned with FCT was former Congressman Loloy. We were together as colleagues in Congress. The Romualdo family had dominated politically the Camiguin island province for a long time up to the present. The circumstances of his undergoing stem cell treatment , however, are not yet clear. My cursory check results showed that he did NOT get FCT from Villa Medica in Germany. This will have to be further validated though.

The other prominent name was former Customs official (and now with Dangerous Drugs Board) ANTONIO BEBOT VILLAR. We were together in the Arroyo administration. He said he and his wife had FCT in a 5-star hotel in Metro Manila, by German and Thai doctors but NOT in Germany. His condition allegedly worsened after the treatment. MY OWN STORY I will not venture to further deal on those incidents simply because they are now subject of further close look by the authorities. And I am not privy with the true facts surrounding their cases. But I will deal on some information that are of my own personal knowledge and the personal experience I and my wife BETH can competently attest to.

As I have written previously, I and my wife Beth traveled all the way to EDENKOBEN, GERMANY last November, 2012 some seven (7) months ago for FCT in the VILLA MEDICA (VM) clinic facilities as an alternative remedy to her deteriorating kidney condition. We were NOT assured that there would be positive results by VM representatives but we took the chance after I made extensive research and consultations with doctors and experts. We even traveled to Bangkok, Thailand to make further inquiries. We were encouraged by reports of well-being and regenerative effects on vital organs. And we took efforts to talk to those who themselves underwent the procedure. We gathered that VILLA MEDICA and its FCT, using fresh stem cell from the fetus of clinically controlled and raised sheep had been recognized, authorized, licensed and closely monitored by stringent standards imposed by GERMAN HEALTH AUTHORITIES of the German government. VILLA MEDICA, founded in 1963 had also a long track record of about 50 YEARS. Fresh cell therapy was pioneered by Dr PAUL NIEHANS in 1931. Another doctor in 1980, GUNTER BIOBEL scientifically dissected the technology and was awarded in 1999 the Nobel Prize in Physiology or Medicine.

After some soul-searching and weighing our options, we decided and took the trouble of traveling to Germany at some cost even when we were told that there were stem cell treatments also being done in the Philippines, at more considerable costs, although still in their infancy stage. We had no way of verifying the reliability of local Philippine FCT providers due to their fairly recent track record. When I checked with St. Lukes Hospital Regenerative division at Global City, the division chief told me they were into this procedure: harvesting human stem cells from the patients themselves, usually from the bone marrow, churn them for 2 weeks in the laboratory using German-made machines and injecting them back to the patient over a 12 month period. However she declined to cite or give an example of a success story simply because they had been into the procedure fairly recently. Also, we were informed that to achieve optimum results, fresh stem cells must be injected (in the buttocks) within two hours from its harvesting from the donor fetus. So getting the FCT infusion right there in the clinic in Germany was far better than having the injectables flown from Germany or elsewhere and get the infusion in Manila, travel time obviously reducing the stem cells efficacy or potency. More importantly, seven months ago, there were NO clear Philippine regulations yet governing FCT, due to its infancy, to give us some level of reasonable comfort and assurance. On the other hand, the procedure in Germany we were told adhered to strictest German standards imposed by the German government. These regulations even cover the growing and maintenance of donor sheep and the harvesting of stem cells from 18-week old fetus under clinical control and conditions. And specific success stories were many.

And more importantly, we were in a desperate mode due to the continuous decline of Beths kidney conditions. As preparatory steps, Beth went through a series of tests which were screened and studied by her doctors in Manila and even through German doctors in Villa Medica in Edenkoben who had to make the final decision whether she was qualified to get the treatment. Even her Nephrologist who happens to be also a family friend and a known kidney transplant surgeon at the National Kidney Institute recommended that we try FCT. That sealed our decision.

So, off we went to Germany last November, 2012. Of course at great expense. (Treatment costs EURO 15,000 or about 830,000 PHP ) But nonetheless. AFTER 7 MONTHS Today, seven months after the treatment, and in contrast to the sketchy stories surrounding the cases of my friends ERICO, LOLOY and BEBOT as reported in the media, our own testimonials of the FCT at VILLA MEDICA are a bit different from those horror stories. I also personally met and discussed with others who themselves went to the German facility for FCT and our testimonials coincided.
