Embedding the Power of Stem Cell Therapies: California's Efforts and the Quest for $5 billion More

California's $3 billion stem cell agency has financed a lot of research that winds up as dense, inaccessible articles -- at least to the general public -- in costly scientific journals with imposing pay walls.

Sometimes, however, stories of hope and stem cell progress do emerge that are likely to resonate with the state's citizens. They are the folks who voted to create and finance the agency in 2004 and who are expected to be asked again for more billions next year.

One such example involves the cases of Evangelina Padilla-Vaccaro of Corona, Ca., Ronnie Kashyap of Folsom, Ca. From birth they suffered from what is known as the "bubble boy" disease.

Both children were born with severe combined immune deficiency (SCID) that is ordinarily fatal. But as the result of clinical trials that were backed with millions from the stem cell agency, both are still alive today. (See here and here.)

The agency is formally known as the California Institute for Regenerative Medicine (CIRM). It has a blog called The Stem Cellar. Today it published an evocative piece written by the mother of another child with the "bubble boy" affliction. 

In her case, the work that has saved her son's life was not financed by CIRM. But the agency carried her story as a powerful affirmation of the importance of stem cell research, wherever and however it is supported. 

Kevin McCormack, director of communications for the agency, wrote, 

"CIRM's mission is very simple: to accelerate stem cell treatments to patients with unmet medical needs. Anne Klein's son, Everett, was a poster boy for that statement. Born with a fatal immune disorder Everett faced a bleak future. But Anne and husband Brian were not about to give up. The following story is one Anne wrote for Parents magazine. It's testament to the power of stem cells to save lives, but even more importantly to the power of love and the determination of a family to save their son."

Anne Klein's article is just what supporters hope will be embedded in the hearts of voters come November 2020 when the next round of financing for CIRM will be on the ballot. 

These sorts of stories, however, have received little attention in the mainstream media, whose reporting resources are ever-diminishing. The media are hard-pressed financially and otherwise nowadays as their once highly profitable business models have been hard hit by the impact of the Internet. 

Nonetheless the agency is assiduously pumping out information and stories on what it calls its value proposition. Here is the final line in the item that CIRM published today:

"You can read about the clinical trials we are funding for SCID here, here, here and here."

A Peek Inside the California Stem Cell Research Machine: $25 Million, Babies, Bonds and Dwindling Cash

California's stem cell agency this week dished up rare public details of an advanced effort to create "transformative" therapies that would help cure afflictions ranging from diabetes to always fatal immune disorders.

The disclosure involves Stanford University researcher Judith Shizuru, severely ill babies, toxic chemical treatments, delays in clinical trials and stem cell agency board members who are acutely aware of the $3 billion agency's rapidly dwindling resources.

All this plus more is on the table Thursday at a meeting of the directors of the California Institute for Regenerative Medicine (CIRM), as the agency is formally known. 

The agenda nominally contains one item, an application by Shizuru for $6 million from CIRM. But the issues reach back to 2013 and provide insight into difficult research pathways and how the agency manages its programs. 

At the top of the matter is the fact that the state agency expects to run out of cash for new awards by the end of this year. It is pinning its hopes on a proposed $5 billion bond measure on the November 2020 ballot.  Meanwhile, directors are trying to raise privately $200 million to tide it over until then. 

Avoiding Toxic Chemotherapy

That was the backdrop Wednesday Jan. 30 when directors convened to consider application number CLIN2-11431 by Shizuru for $6 million. She is seeking a way to avoid chemotherapy treatments and their toxic side effects in the case of a rare genetic affliction often referred to as the bubble baby syndrome. 

In December, CIRM's grant reviewers, meeting behind closed doors, approved Shizuru's application, an action that nearly invariably is rubber-stamped by directors. But last month was different, and a bit of CIRM history was brought up.

Shizuru received  a $19 million CIRM award in 2012 which has led to a phase one clinical trial with positive results for her therapy. Cost per each of the six patients so far averages $917,000, according to a CIRM document. 

However, additional patients are needed, along with more funding, before the potential product can reach the marketplace. The average cost of per patient will run about $333,333 during the final portion of the phase one trial.  Her latest application is aimed providing assistance with those costs. 

Questions about Delays and Co-Funding

Last month, questions arose among directors about months of delays in the clinical trial and a current shortfall in co-funding, among other things.

Steve Juelsgaard

Steve Juelsgaard, a former Genentech executive and chair of the directors' Finance Committee, said, 

"It's not clear to me that they're being frugal with the money that they have been given."

Juelsgaard also said,

"Delay doesn't necessarily add up to more money. They obviously spent the money on something that they didn't anticipate or under-budgeted or something. There's something more to it."

Another director, Jeff Sheehy, chair of the board's Science Committee, said,

"Financially, it seems very muddy to me."

Other directors weighed in as well, ultimately leading to a motion to delay action on the application to provide more time to find answers to questions.

At that point, Shizuru, who was in the audience, rose to respond.

"I understand CIRM's concerns, and I can see you're very thoughtful about how this money is being spent," she said, according to the transcript.

 The Sheehy-Shizuru Exchange

The Stanford researcher said that without additional funding the trial would have to suspend enrollment of additional patients, prompting this exchange between her and Sheehy.

"Shiruzu: Budgetarily we're better off using it (the remaining funding) to continue to follow the patients that we've already transplanted. From that budgetary standpoint, we should delay the trial. We should delay treating any more patients on the trial.

"Sheehy: So Stanford won't front you 1.6 million to (treat) patients if we don't give you the money today?

"Shiziru: I hesitate to say what they would do.

"Sheehy: To Stanford...they would actually put patients at risk?

"Shiziru: I'm not at liberty to say what Stanford would do."

Stanford is the No. 1 recipient of CIRM awards, chalking up $379 million over the past 14 years. It also has always had a member on the CIRM board of directors, who is not allowed to speak or vote on awards to Stanford.

Following Shizuru's comments, CIRM directors approved the motion to delay action until this week's meeting. Since the January session, Shizuru has provided the agency with more than five, single-spaced pages of explanation about her research, plus other material that has been kept under wraps for what CIRM has indicated are proprietary and legal reasons.

The information from Shizuru, as well as additional documents from CIRM, provided an unusual, public look into the agency's grant-making process as well as the hurdles encountered in advanced clinical research. In the past, reviews of applications approved by reviewers have received little or no discussion.

Shizuru's Perspective

In her material, which is available on the agenda for this week's meeting, Shiruzu said one, eight-month delay was caused by CIRM itself because of internal concerns. Another nine-month delay was caused by age-restrictions on patients.

"Significant delay" was also caused because of what might be called a supply and demand issue. The bubble baby syndrome is rare. Only one in out of 50,000 to 100,000 births results in a baby with the affliction: severe combined immunodeficiency.

Three other clinical trials are also competing for those rare patients. 

Nine letters of support were received by CIRM supporting the research, with some describing the potential result as "transformative." The letters also said Shizuru's approach could find use in a wide range of other afflictions, an expectation also agreed upon by CIRM. 

Shizuru said she is working on securing the needed co-funding for her first award, which is not yet concluded. As for commercialization, she said she and her colleagues have formed a company, whose name was not disclosed. She said she has a letter of support from one investor regarding "an intention to co-fund pending completion of due diligence."

In a final comment during the vote last month to delay consideration, one CIRM board member, a San Diego patient advocate for Parkinson's disease, praised the board's close examination of the application. David Higgins said, 

"I want to acknowledge fellow board members (for) their continued concern about spending taxpayer's money wisely because I think this is a great example of that."
