California Kicks Off Major, New Foray into Gene Therapy: First by Any State in the Country

California today became the first state in the nation to launch itself into the sizzling field of gene therapy, backed by tens of millions of dollars and with the hope of creating treatments that could permanently cure afflictions ranging from hemophilia to cancer.

The move came today as the board of the $3 billion California stem cell agency opened its doors to funding gene therapy research that has reached the most advanced stage, clinical trials. The agency said that gene therapy -- minus stem cells -- is "valuable and worthy of pursuit."

"This is where the science is going," said Jeff Sheehy, chairman of the CIRM board's Science Subcommittee, at hearing earlier this month,

The state stem cell program has allocated $143 million for research programs next year that could include gene therapy.

A document prepared by the leadership of the agency, formally known as the California Insitute for Regenerative Medicine (CIRM), said, 
"For CIRM and the patients it aims to serve, it is vital to support technologies which prove to be highly complementary and augmenting to stem cells, such as gene therapy."
Gene therapy treatments are expected to be quite expensive, with some forecasts running in the $1 million to $2 million range. Supporters of gene therapy argue that the cost is justified because gene therapy can be a total cure that would eliminate the need for also very expensive lifelong treatments of chronic diseases. 

In its action today, the stem cell agency did not announce any specific research awards. Rather it created a procedure for declaring that a gene therapy project with a regenerative element is a "vital research opportunity."  That would allow CIRM to fund such a project under the terms of the ballot initiative that created the agency in 2004. Today's action is the first time that the agency has acted to use the "vital opportunity" provision. 

CIRM has budgeted $143 million for next year in two areas where the new gene therapy initiative could come into play, clinical trials along with translational research that is intended to advance basic research into clinical stages. 

The agency's new foray comes as its cash is running out. By the end of next year, it expects to have no more funding for new research. The agency is pinning its hopes of survival on a $200 million plus private fundraising effort this year and voter approval of a yet-to-be-written ballot initiative on the November 2020 ballot. 

The gene therapy field is moving swiftly and could generate a result that would resonate with voters and help to win approval of an additional $5 billion for CIRM.

CIRM board members have acknowledged that its new gene therapy effort will mean more competition for the state's research dollars, including possibly less for stem cell research, which is the agency's fundamental reason for being.


The agency, however, has already awarded millions of dollars for gene therapy research that has a stem cell link, including a program at UCLA that has led to a successful treatment for what is known as the "bubble boy syndrome." However, that research has not yet moved into the marketplace.

The target of the UCLA treatment is an immune deficiency that is fatal and for which there is no successful treatment outside of the experimental trials that are still underway. 

Bloomberg News has reported that Scott Gottlieb, head of the federal Food and Drug Administration(FDA), has described the field as "somewhat breathtaking." More than 500 experimental treatments are in the pipeline. 

Gottlieb has said that he expects the FDA to approve 40 gene therapies by 2022 and possibly a cure for sickle cell anemia within 10 years. CIRM is deeply involved in a major national push on sickle cell supported by the National Institutes of Health.

Combating Stem Cell Snake Oil: A Primer From a California Researcher

Hundreds of dubious, unregulated stem cell clinics exist throughout the country with the most in California. Desperate people seeking help have been maltreated and fleeced. What to do?

UC Davis stem cell research Paul Knoepfler has produced a useful guide to reporting dubious
activities along with a list of state and federal agencies that could have a role.

In an item on his blog last week, Knoepfler wrote,
"I would emphasize concrete reasons for concern such as the use of an unapproved stem cell drug product by the clinic, a physician practicing outside their area of expertise so putting their patients at risk, false marketing, and potential or documented (if they’ve already happened) patient harms.

"For some clinics that aren’t led by physicians, I would also emphasize the risks of non-physicians such as chiropractors or Ph.D.s doing procedures for which they aren’t trained or licensed. I think patients (or people communicating on their behalf) making complaints about clinics and their personnel will have the greatest impact."
Knoepfler continued,
"We can make a difference by pushing back on the worst clinics. Of course, not every action by those of us in the stem cell arena who are concerned about predatory clinics will hit a bullseye to make real change, but sometimes it has happened in the past and will happen again in the future too."
I would add that the activities and stories that emerge from these dubious enterprises damage the reputation of the field as a whole. Indeed, when I talk to folks in the general public, the clinics' offerings are the most often mentioned reference they have.

As California's stem cell agency moves closer to seeking more billions from voters in 2020, fraudulent stem cell activity could create much confusion about the legitimacy of the entire field. Supporters might want to keep that in mind. But critics should as well. Fleecing the public with unproven therapies is unhealthy for those who are swindled but also for society in general.

California's Stem Cell Agency Opening Door to Pumping More Millions into the Sizzling Gene Therapy Market

Gene therapy graphic from FDA
The California stem cell agency today crossed a key threshold into the "somewhat breathtaking" and potentially multibillion-dollar world of gene therapy, a field that it has skirted previously. 

The action came when a key panel of the agency's governing board this morning approved its first-ever procedure for awarding millions of dollars for research not connected to stem cells. 

"This is where the (regenerative) science is going," said Jeff Sheehy, chair of the Science Subcommittee of the board of the California Institute for Regenerative Medicine (CIRM), as the Oakland-based agency is formally known. 

Under Prop. 71, the ballot initiative that created the $3 billion agency in 2004, CIRM is limited to financing research involving stem cells in some fashion. However, a provision of the measure also allows the support of a "vital research oppportunity" under certain conditions. Today's action formalizes the process for making that finding. 

CIRM said in in a document that it is "vital" that the agency expand its horizons.
"CIRM has supported projects that combine stem cell and gene therapy technologies, such as the gene-corrected stem cell transplants at UCLA that essentially cured 5-year old Evangelina Padilla Vaccaro and several CAR-T cell approaches using stem memory T cells that aim to tackle various cancers. 
"The support of stem cell research that contributes to these treatments is and will continue to be the core of CIRM funding. However, treatment opportunities in regenerative medicine that utilize gene therapy technologies but not necessarily stem cells are also valuable and worthy of pursuit."
The agency's statement continued,
"The field of regenerative medicine brings together technologies that include stem cells, gene therapy, and tissue engineering that in many cases combine to produce a therapeutic product. In some cases, one technology leads the way. For CIRM and the patients it aims to serve, it is vital to support technologies which prove to be highly complementary and augmenting to stem cells, such as gene therapy."
Several directors noted during today's meeting that the change could lead to less cash for purely stem cell projects. 

The field of gene therapy has attracted widespread interest within the regenerative medicine industry and among federal medical regulators. Scott Gottlieb, commissioner of the Food and Drug Administration, earlier this year announced steps to speed development of the therapies. 

"'The pace of progress in gene therapy has been somewhat breathtaking,' he (Gottlieb) said, with more than 500 experimental drugs now in development. 'The promise is becoming very much a reality.'"
In April, Novartis AG ponied up $8.7 billion to buy AveXis Inc., of Illinois to strength its efforts to produce a marketable gene therapy.

Gottlieb has said that he expects the FDA to approve 40 gene therapies by 2022 and possibly a cure for sickle cell anemia within 10 years. 

CIRM's new gene therapy policy will go before the full CIRM board one week from today where it is expected to be approved. Additional information on the policy can be found on the Science Subcommittee agenda.  Sphere: Related Content

An FDA High Sign for a California Stem Cell Agency Bet: San Diego Biotech Business Earns FDA Speed-Up Approval

A San Diego firm backed by nearly $24 million from the California stem cell agency scored this week with a special designation from the federal government that could help speed approval of its therapy for a type of blood cancer. 

The firm is Poseida Therapeutics, Inc., which is testing the safety of a therapy for a type of blood cancer in a phase one clinical trial. 

The firm announced yesterday that the Food and Drug Administration (FDA) had granted Regenerative Medicine Advanced Therapy (RMAT) status for the adult stem cell-connected treatment. The designation is intended to expedite development of the multiple myeloma therapy. 

Eric Ostertag, CEO of the firm, said in a news release, that Poseida's potential treatment, P-BCMA-101, "is the first anti-BCMA CAR-T therapy to receive RMAT designation from the FDA and underscores the urgent need for new treatment options for multiple myeloma." 

He continued, 
“Initial Phase 1 data presented at the CAR-TCR Summit earlier this year included encouraging response rates and safety data, including meaningful responses in a heavily pretreated population...."
Ostertag said the firm expects to have more data by the end of the year. 

The stem cell agency, known formally as the California Institute for Regenerative Medicine (CIRM), has invested in 49 clinical trials. Five have garnered RMAT designation, which can significantly speed development of a commercial product. As of September, the FDA had granted only 24 RMAT designations nationally. 

Last Sepetember, Geoff Lomax, CIRM senior officer for medical affairs and strategic centers, wrote in cell&gene that the two-year-old, RMAT program streamlines therapy development by enabling possible priority FDA review and accelerated federal approval. 

Longitude Capital of Menlo Park, Ca., is a major investor in the firm, pumping in tens of millions of dollars.   Sphere: Related Content

 research funding by the California stem cell agency. CIRM chart
California's $3 billion stem cell research program is set to add gene therapy -- minus stem cells -- as research that it will be able to legally finance. 

The change comes as the stem cell agency is looking to generate results that are likely to resonate with voters in November 2020 who may be asked to provide an additional $5 billion in funding for the program. The agency expects to run out of cash by the end of next year. 

Gene therapy has received considerable attention in the last few years. Yesterday, Orchard 
Therapeutics, a British gene therapy firm that has links to CIRM (also see here) and research by Donald Kohn of UCLA, raised $200 million in an initial stock offering. The company said in its prospectus that the total market potential "in the diseases areas underlying our five lead programs could be greater than $2 billion annually."

Kohn has received nearly $31 million in backing from the stem cell agency, which is formally known as the California Institute for Regenerative Medicine (CIRM).

The Science Subcommittee of the agency is expected to approve extension of its gene therapy efforts next Wednesday in a teleconference meeting that will be available globally through the Internet. 

Under the provisions of the ballot measure that created the agency in 2004, the agency is limited in scope. But exceptions are possible if a finding is made that a "vital research opportunity" exists. 

Next week's meeting is expected to formalize the process of making that determination in regards to gene therapy that does not involve stem cells. It will require a 2/3 vote of CIRM's grant review group, among other things. 

Members of the public can participate in the hearing remotely via the Internet or at locations in Oakland, San Francisco, La Jolla, Riverside and Napa. Directions can be found on the agenda. Sphere: Related Content

A $59 Million Matter of Fraud and Hubris: The Anversa Stem Cell Story and Its Fallout

Piero Anversa -- NYTimes photo by Annie Tritt

Fabricated stem cell research and its fallout are back in the news this morning with excellent pieces from the New York Times and the Washington Post involving talk of "temptation" and the weakness of prestigious institutions.

First the piece by Gina Kolata in the New York Times,which includes the first substantial interview with Piero Anversa, the former Harvard researcher now identified as having produced more than 30 studies containing falsified or fabricated data dealing with heart research. Kolata wrote,
"Dr. Anversa’s story has laid bare some of the hazards of modern medical research: the temptation to embrace a promising new theory, the reluctance to heed contrary evidence and the institutional barriers to promptly stopping malfeasance. Even after three independent researchers were unable to reproduce his findings in 2004, Harvard hired him in 2007 and his lab continued to churn out studies upholding his theory."
Anversa, 80, is now living in New York. He told Kolata in an interview in his apartment that he did nothing wrong and that he was "betrayed by a rogue colleague who altered data in paper after paper."

Kolata has more from Anversa, but also dives into the history and ramifications of the scandal and its implications involving the culture of science. She described the case as "a particularly acrid cautionary tale of scientific hubris."

A couple of highlights from the piece.
  • "'Science at this level is like a battleship, and it’s really hard to turn it around,' said Dr. Jonathan Moreno, a professor of bioethics at the University of Pennsylvania.'People get emotionally invested, financially invested, professionally invested.'" 
  • “'This was a perfect storm of ego, wishful thinking and lack of accountability,' said Dr. Jil C. Tardiff, a professor of medicine at the University of Arizona, and a heart-muscle cell researcher."'
 Kolata concluded:
"It did not surprise some in academia that the bold promises of the research persisted despite the contested evidence. 
 "There was an argument in the philosophy of science about whether there is such a thing as a ‘crucial experiment,' said Dr. Moreno, the ethics professor, referring to a study that answers a question once and for all. 
"'It turns out there isn’t. People can see what they want to see.'"
Carolyn Johnson of the Washington Post covered much of the same ground but has more on suspension of a clinical trial related to Anversa's work. Johnson also pointed out that Anversa received $59 million from the federal government for his research. Harvard has since been fined $10 million by the federal government.  

The trial is in the midst of recruiting patients. Johnson wrote,
"The decision to temporarily pause the trial came 'out of an abundance of caution,' said David Goff, director of the Division of Cardiovascular Sciences at the National Heart, Lung and Blood Institute, who said the trial’s scientific rationale is largely based on animal studies not conducted by Anversa.... 
"Goff said the board charged with overseeing the safety and integrity of the trial was convened last week and NIH leadership made the decision to pause the trial, which has enrolled 125 of 144 patients, to allow a thorough review.
"'Our commitment, first and foremost, is to patient safety. We haven’t seen any safety signals related to the cell treatment, but we can’t do any of our research without the partnership of our participants, and we make a commitment to our participants that their safety is our highest priority,' Goff said. The pause will allow the board to examine the trial and 'assure that it continues to meet the highest levels of adherence to participant safety and scientific integrity.'"

Tax Breaks and $220 Million for California Stem Cell Agency

The California stem cell agency, which is facing its financial demise, is seeking assurances of "continued tax breaks" for private donors who are being courted for $220 million to support the enterprise, Bloomberg Law reported this week. 

The article by Joyce Cutler referred to the effort to bridge a looming and major stem cell funding gap. The agency says it will run out of cash for new awards at the end of next year. But it does not see additional public funding until November 2020, when the agency hopes that California voters will refinance it with $5 billion from a yet-to-be written ballot initiative. 

Cutler wrote,
"Closing the deal, however, involves getting assurances from elected officials of continued tax breaks to get donors to open their checkbooks and keep CIRM operating until another bond measure can be passed." 
CIRM is the abbreviation for the California Institute for Regenerative Medicine, the formal name of the stem cell agency. It was created in 2004 by voters who provided it with $3 billion in state bonds, but no more. 

Asked for comment by the California Stem Cell Report, Kevin McCormack, senior director for communications at CIRM, said,
"With regard to the tax deductibility issue, that’s really out of our hands but, of course, we’re hopeful that all incentives to potential donors are preserved going forward."
Cutler wrote, 
"Contributions to state agencies currently are deductible from income under state and federal law, H.D. Palmer, state Department of Finance spokesman, told Bloomberg Law in an email.
"'Going forward, that’s going to fall to the next folks who get the keys to the car' in the governor’s office and Legislature, who will decide whether the California deductions remain.
"But the federal Internal Revenue Service is considering regulations to disallow deductibility if the tax credit is for more than 15 percent of the contribution. The Tax Cuts and Jobs Act of 2017 limits the amount of state and local taxes (SALT) an individual can deduct on taxes to $10,000 a year. The proposed regulations crack down on state workarounds to the SALT deduction cap."
Jonathan Thomas, chairman of the CIRM board, is leading the effort to raise funds privately. Bob Klein, who preceded Thomas as chairman, has a role but the agency has declined to go into details. Klein is a real estate investment banker and founder and chairman of Americans for Cures, a nonprofit organization supporting stem cell research. 

Klein has said he has a poll that shows that more than 70 percent of Californians support refinancing the agency. But he has declined to release the poll or identify the firm that provided it when asked by the California Stem Cell Report.  

Klein oversaw the writing of the ballot initiative that created the stem cell agency in 2004 and led the electoral campaign on its behalf. He has said he will try again in 2020 if polls show sufficient support. 

At last week's CIRM board meeting, Thomas gave a short report on the private fundraising effort, which has been underway for many months. He did not announce any contributions or discuss the tax break issue. 

At the meeting, board member Jeff Sheehy expressed concern about progress on a possible 2020 bond measure, noting that there is a relatively short amount of time to mount a major political effort.

Art Torres, vice chairman of the board and a former state legislator, said no real effort can be mounted until after the elections next month. Torres and CIRM general counsel Scott Tocher also noted there are legal limits on what the agency can do in terms of a ballot campaign.
