Has CIRM Funded Stem Cell Research that Bush Would Have Banned?

When California voters approved creation of an unprecedented, $3 billion stem cell research program more than six years ago, they were told the money would go to finance research that then-President George Bush had banned.

Has that actually happened? Yes, but mainly no, according to a research paper published in Nature Biotechnology in December 2010.

In the first-ever such analysis of CIRM grants, Aaron Levine, assistant professor in the School of Public Policy at Georgia Tech, reported that through 2009 only 18 percent of California's dollars went for grants that were "clearly" not eligible for federal funding.

Levine's finding has implications for another, multibillion-dollar bond ballot measure that CIRM Chairman Robert Klein has proposed. The campaign for such a measure would have to address the question of whether the promises of the 2004 ballot initiative that created CIRM have been fulfilled.

CIRM does not offer on its web site figures that can be compared to Levine's calculations. The agency does present some statistics about the amount of funding for embryonic stem cell research, but makes no effort to break out the percentage of grants that would not have received funding during the Bush years.

Levine's numbers on California were part of a broader look at state funding of stem cell research in recent years. He reported that by the end of 2009, six states had awarded nearly 750 grants totalling $1.25 billion. California accounted for $1 billion of the total. Per capita funding amounted to about $1 in Illinois and nearly $28 in California.

In all of the states, percentages were low for research that was clearly ineligible for federal cash under the Bush standards. Levine wrote,

"Most state hESC funding appears to have supported research also eligible for federal funding during the Bush Administration. This finding is surprising, given the explicit intent of several state programs to preferentially support science not eligible for federal funding, but likely reflects the nature of the grant proposals state agencies received, particularly given the number of grants states awarded to scientists relatively new to the field of hESC research.

Levine continued,

"Several factors could explain the relatively small share of grants that went toward clearly ineligible research. Some scientists who wished to pursue this research may have been unable to access the raw materials or acquire the intellectual property rights required to do so. Alternatively, these findings could simply reflect scientific interest. The discovery of induced pluripotent stem cells may, for instance, have reduced scientific interest in the derivation of new hESC lines. Finally, these findings may reflect a preference on the part of scientists to use well-established and well-studied hESC lines. This last explanation may be particularly relevant for new scientists entering the field of hESC research, as using recognized cell lines may give their initial research efforts greater credibility."

In California, another factor enters into funding for Bush-banned research, particularly given the 2004 campaign promises. CIRM makes overt decisions about what to fund. Its RFAs spell out what is acceptable and non-acceptable. The agency could have specified that it would not fund any research that would be eligible for federal funding. But whether that would have been "good science" is another question. CIRM also spent nearly $271 million on new labs at many of its directors' research institutions, diluting the percentage that would be construed as financing Bush-banned research.

We are querying CIRM concerning Levine's statistics.

Levine also reported that the state stem cell research efforts appear to have drawn new scientists into the field, with the largest impact occuring in California. He wrote that 42 percent of those funded in this state appeared to be fresh to the field.

In addition to the Nature Biotechnology piece, Levine has created an online database of state grants that he plans to update regularly. In an email to the California Stem Cell Report, he said,

"While CIRM already makes this information readily accessible, some of the other state programs do not and I hope this database will facilitate comparisons among the various programs and prove to be a useful tool for people interested in state stem cell programs. "

National Stem Cell Doings: Rat Brains and Legal Wrangling

How is it going to go in the federal case involving hESC stem cell research?

A UC Davis scientist opines – that's one of those media words you see in print but rarely hear anyone utter – that the matter could go 2-1 for funding of research but possibly 2-1 against, given that two of the judges are appointees of young Bush.

You can read more from Paul Knoepfler here on his analysis of today's proceedings along with comments from his readers.

Also on the national stem cell front – sort of – is a column by the Maureen Dowd of the New York Times. On Sunday, she quoted Stanford's Irv Weissman on some monkey business in the US Senate race in Delaware.

He made his comments to Dowd in response to a 2007 statement by the Republican candidate in Delaware, who shall remain nameless. The candidate declared,

“American scientific companies are crossbreeding humans and animals and coming up with mice with fully functioning human brains.”

Weissman, who knows something about rodents, performed the first experiments injecting human brain-forming stem cells into the brains of immune-deficient mice 10 years ago.

Dowd wrote,

“(Weissman) assured me that the mice did not suddenly start acting human. 'There were no requests for coffee from Minnie,' he said. 'The total number of human brain cells in the mouse brain was less than one in a thousand. I don’t think we would get a mouse with a full human brain. And even if the mouse made it to a human mouse it would still have a mouse-brain offspring.'”

Embryonic Stem Cell Treatment Ruled Out for California Jockey

California jockey Michael Martinez, whose spine was severely damaged earlier this month, will not be enrolled in Geron's clincal trials for hESC treatment, the only such in the nation.

Reporter Matt Hegarty of the Daily Racing Form wrote this afternoon,

“Specialists at Northwestern University near Chicago have decided that the rider Michael Martinez is not a candidate for a clinical trial using embryonic stem cells to treat spinal-cord injuries, according to the track physician at Golden Gate Fields, where Martinez was severely injured in a fall on Sept. 12.

“Dr. David Seftel, the physician, said that the neurosurgeons conducting the trial had concluded from Martinez’s medical records that the jockey’s spinal cord had been too severely damaged to consider Martinez for the trial. Seftel and Martinez’s family had hoped that the treatments, which have shown some promise in studies on rats, would be able to mend the rider’s severed spinal cord. Martinez is paralyzed from the waist down.

“The family received the news that Martinez would not be admitted to the trial on the same day that Martinez’s fiancé, Charlotte, went into labor and was admitted to Highland General Hospital(in Oakland, Ca.), where Martinez is currently receiving treatment. The baby was expected to be delivered later on Tuesday, Seftel said.

"'It’s a day of extremely mixed emotions,' Seftel said."

The New York Daily News on Sunday carried a lengthy story on the accident, in which an 1,100-pound horse running at 35 miles an hour fell on Martinez. The story by Christian Red discussed Geron's involvement.

He wrote,

“The Menlo Park, Calif.-based biotechnology company Geron, which has been approved to conduct clinical trials of stem cell treatment on humans, after the Food and Drug Administration lifted the hold on the company's Investigational New Drug application July 30, would possibly conduct the treatment.” 

Red continued,

“But Martinez is in a race against time, even if he is eligible to get the treatment. According to Dr. Ed Wirth, the medical director of regenerative medicine at Geron, 'stem cells need to be injected between seven and 14 days after the spinal cord injury because that's the time window in which we've seen the best chance of benefit in the animal studies.'

“Geron plans to have seven facilities around the country opened to carry out these trials, and although the company has not made a public announcement, Seftel said that one of the facilities at Northwestern Universityin Evanston, Ill., is currently set up to receive applications for candidates.”

The Racing Form's story this afternoon said,

“Martinez is expected to be transferred late on Wednesday to Santa Clara Valley Medical Center, which runs a rehabilitation clinic that specializes in spinal-cord injuries. Seftel and Martinez’s cousin, the rider Alex Solis, are also exploring experimental treatments with adult stem cells, though, in studies, those treatments have not shown to be as promising as the embryonic stem-cell treatments, Seftel said.”

Legal Wheels Turn: Ban on hESC Funding Temporarily Removed

The nation's stem cell scientists received a reprieve today, courtesy of a federal appellate court that put a hold on an earlier order to halt federal funding of hESC research.

Gardiner Harris of the New York Times wrote:

"The appeals court ruling could save research mice from being euthanized, cells in petri dishes from starving and scores of scientists from facing a suspension of paychecks, according to arguments the Obama administration made in the case. It could also allow the National Institutes of Health to provide $78 million to 44 scientists whose research the agency had previously agreed to finance."

Rob Stein and Spencer S. Hsu of the Washington Post wrote:

"(T)he appeals court made it clear it was not making a final decision about the case, which means the reprieve could be short-lived and the fate of the funding could continue to be whiplashed by seesawing court rulings."

The next court action is not expected to come until sometime after Sept. 20, the deadline for filing additional arguments in the case.

The legal brouhaha makes clear several facts concerning research funding. If you are a scientist, your research is not secure unless you are paying for it yourself. NIH funding is subject to the vagaries of the courts and Congress. Private funding comes with its own set of strings, which generally are not revealed to the public, but they are there. And despite the assurances of the California stem cell agency, its funding can be threatened under some circumstances, as we saw in 2009. CIRM's resources are clearly subject to the state's ability or desire to borrow money and issue the state bonds that are the agency's only real source of cash.

California Radio Talk Show on hESC Ruling

Art Torres, co-vice chairman of the California stem cell agency, will be one of the guests on a radio talk show tomorrow at 9 a.m. PDT on station KQED in San Francisco dealing with this week's hESC ruling. You can listen to the program live on the Internet.

The station said,

“National Institutes of Health director Francis Collins said Tuesday that the recent court ruling blocking federally funded research on human embryonic stem cells won't affect grant payments that have already been paid out this year. But the institute will freeze its reviews of new grants of this type. Although California's $3 billion stem cell initiative is not affected, we talk about the ruling and its potential impact on Bay Area biotech. Guests include, Dr. David Stevens, chief executive officer of Christian Medical and Dental Associations; Dr. Helen Blau, professor and director of Baxter Laboratory for Stem Cell Biology at Stanford University; Tom Abate, staff writer covering economics for San Francisco Chronicle; and Art Torres, former chairman of the California Democratic Party and vice chair for the board at California Institute for Regenerative Medicine.”

The Latest from the NIH re the hESC Ruling

UC Davis stem cell research Paul Knoepfler this afternoon reported on the latest from the NIH on the federal court ruling on hESC research.

Writing on his blog, he quoted the text of the statement and then offered a comment.

“Pursuant to a court order issued August 23, 2010, NIH is not accepting submissions of information about human embryonic stem cell lines for NIH review. All review of human embryonic stem cell lines under the NIH Guidelines is suspended. The February 23, 2010, proposal to revise the Guidelines is also suspended.

“My interpretation of this is that basically all the changes to embryonic stem cell policy under the Obama administration and all the federally funded use of ES cell lines approved under the new guidelines during this administration is suspended. No one should bother submitting new lines for approval and those that were under review are not going to be reviewed any more. All of that is frozen.”
