The $50 Million, Semma-Melton Quest: Looking for a Cure for Diabetes

An eminent Harvard stem cell researcher who is searching for a cure for an affliction that plagues 29 million Americans stood on a San Francisco stage this week and spoke of "things we don't understand."

The scientist is Doug Melton, who is on a deeply personal quest for a cure for diabetes. Both of his children have the disease. And the state of California is helping out on his search with $5 million.

The occasion for Melton's remarks was the presentation of the Ogawa-Yamanaka Stem Cell Prize, a $150,000 award for his work in cellular reprogramming.

Here is how Hannah Robbins of the Harvard Gazette described the results of Melton's research:
"As a pioneer in programming insulin-producing beta cells from stem cells, Melton’s lab can now generate therapeutic quantities of functional, stem cell-derived beta cells, which Melton hopes will someday soon replace the life-saving yet painful daily insulin injections for diabetics."
The $5 million from California is a grant made last March by the state's $3 billion stem cell agency, formally known as the California Institute for Regenerative Medicine (CIRM).

The cash is going to a firm in Cambridge, Ma., called Semma Therapeutics, Inc., which Melton co-founded and which is named after his two children, Sam and Emma. Melton now serves on the firm's board of directors. The business is only two years old, but has raised roughly $50 million to translate Melton's work into actual treatments.

His grant application to CIRM in March was titled simply "Personalized Cell Therapy for Diabetes." The proposal (application number TRAN1-08561) received a score of 90 out of 100 from the agency's scientific reviewers who are from out-of-state. A summary of the closed-door review said the proposal was "strong, well-­designed, feasible. and high impact." The research "has excellent product development plans and great regulatory support," reviewers said.

The stem cell agency is limited to funding only work that is done in California. Semma announced earlier this month that it has set up arrangements with UCLA, Cedars-Sinai and the City of Hope in the Los Angeles area to generate "suitable clinical grade" cells from patients and "to establish a path leading to the transplantation of these cells back into patients in a clinical trial."

Peter Butler, chief of Endocrinology, Diabetes and Hypertension at UCLA, will be dealing with patient selection. Dhruv Sareen of the Induced Pluripotent Stem Cell Core Facility at Cedars-Sinai will direct derivation and analysis of pluripotent stem cells from each patient’s blood. The cells will be transferred to the City of Hope for manufacture of products for clinical trials.

Overseeing the entire project is Felicia Pagliuca, principal investigator on the CIRM grant. She is also scientific co-founder of the firm, the vice president of Cell Biology Research and Development and a lead on the original research in Melton's lab.

The financial backers are led by MPM, a venture capital firm with offices in South San Francisco and Cambridge, Mass. Robert Millman, formerly of MPM, is CEO of Semma. Other investors include Medtronic, Novartis, Fidelity Biosciences, Arch Venture Partners and the Juvenile Diabetes Foundation.

Semma is still hiring and has openings listed for five positions on its web site, ranging from scientists to a director of device development and manufacturing.

Here is a video recording of the award ceremony in which Melton discusses his research and "the things we don't understand" in the science.

(Editor's note: An earlier version of this story contained an inaccurate description of the roles of Cedars-Sinai and the City of Hope involving the CIRM-funded work.)

A Nearly Three-Decade-Long Stem Cell Tale in California

Kris Boesen, patient in Asterias trial -- photo from CIRM
One could say that the latest news involving human embryonic stem cell research and the California stem cell agency stretches back nearly 27 years. 

It was then -- in 1990 -- that Geron, Inc., was incorporated by Michael West who began what eventually turned into a quest for a stem cell therapy for treatment of spinal cord injury.

Yesterday, the Golden State's stem cell research effort carried an item on its blog, The Stem Cellar, dealing with the latest chapter in that quest. The headline said,
"Full Steam Ahead: First Patient is Dosed in Expanded CIRM Spinal Cord Injury Trial"
In the piece, Karen Ring, website manager for the stem cell agency, celebrated the latest patient news concerning the trial which is backed by a Menlo Park, Ca., company called Asterias Biotherapeutics.  Ring said,  
"Inspiring stories like that of Kris Boesen, who was the first AIS-A patient to get 10 million cells in the Asterias trial and now has regained the use of his arms and legs, are the reason why CIRM exists and why we are working so hard to fund promising clinical trials. If we can develop even one stem cell therapy that gives patients back their life, then our efforts here at CIRM will be worthwhile."
Michael West, Biotime photo
The tale of  Michael West, his research and his companies is long and convoluted. The short version is that he is now co-CEO of Biotime, Inc., of Alameda, Ca., which spawned in 2012 Asterias Biotherapeutics, Inc., of  Menlo Park, Ca. 

Geron is out of the business of human embryonic stem cell research. In 2011, it abandoned the nation's first-ever hESC trial for financial reasons. The effort was sold to Asterias in 2013. In 2014, the $3 billion California stem cell agency jumped in with $14.3 million for Asterias. 

 Asterias' stock closed at $4.56 yesterday. Its 52-week high stood at $5.75. Its 52-week low was $2.30.

A Look at Stem Cell Treatments in Mexico with Ties to California

First part of KBPS' stem cell treatment series

A San Diego television station this week aired a solid series exploring the world of unproven stem cell treatments, including therapies in Mexico and involving a California company.

The work was produced on KBPS by David Wagner and ran as a two-part series(see image above). UC Davis researcher Paul Knoepfler, who earlier this year documented the existent of 570 unregulated stem cell clinics nationally, described Wagner's work as "an important new piece...on for-profit investigational stem cell treatments."

Companies mentioned by Wagner included Stemedica Cell Technologies, Inc., Global Stem Cell Health, Inc., both in the San Diego area, and Hospital Angeles in Tijuana, just south of San Diego in Mexico.

Stemedica is the firm connected to nationally reported treatments of the late hockey great Gordie Howe and former professional quarterbacks John Brodie and Bart Starr. (See here and here.)

California Stem Cell Research: $639 Million Left in the Golden State's "Big Bucket"

Randy Mills, head of the California stem cell agency, calls the cash
available for research awards "the big bucket." CIRM graphic
California's ambitious stem cell research agency has $639 million remaining in uncommitted cash as it continues to seek therapies and perhaps cures for afflictions ranging from spinal injury to diabetes.

Randy Mills, president of the 12-year-old program, announced the figure today at a San Diego meeting of the agency's governing board. He also said the program, formally known as the California Institute for Regenerative Medicine (CIRM), is expected to run out of funds in June 2020.

CIRM is financed by money that the state borrows -- $3 billion in bonds approved by California voters in 2004. Using borrowed money also leads to interest costs, increasing the ultimate taxpayer expense to roughly $6 billion. However, that estimate dates back to 2004 and no fresher figure has been produced by the state.

Mills reminded his directors that the agency is allowed only $180 million for operational expenses over the life of the program. About $61 million remains for those expenses.The current annual operational budget of $16 million pays for the roughly 55-person staff  to oversee $900 million in active awards and to make new awards.

The agency has handed out $2.1 billion over its life but many of those research efforts are finished. No therapies have been developed for widespread use.

The agency also has a "return rate" of 3 percent to 5 percent on awards.  The "return" is cash that is left over from an award or that is returned to the agency when a researcher does not meet research milestones, and the award is cancelled.  The returned cash is running at about $40 million annually.

Just what will happen to the agency come 2020 is unclear. Mills today said he and his team are monitoring the funds carefully so that awards and the operational funds run out at the same time.

The agency also may begin lose key staff as time passes and no plan for 2020 emerges, a possibility that Mills has publicly discussed, albeit briefly.

As for future funding, thoughts about another bond issue, public-private partnerships and more legislative funding have been bandied about. But nothing concrete has yet emerged.
Operational funds are described as "the little bucket" by Mills. CIRM graphic

Time to Crank Up the Stem Cell Comment Machine and Weigh in on Proposed Federal Regulation

Folks interested in seeing more or less or different federal regulation of stem cell treatments and research have until Sept. 27 to file their arguments with the Food and Drug Administration (FDA) following two days of public hearings earlier this week. 

Patients, researchers and representatives of regulated and unregulated companies turned out personally Monday and Tuesday for FDA hearings on its new proposals. Witnesses included Randy Mills, president of the California stem cell agency. Questions were asked by an FDA panel but no conclusions reached. 

For those who missed the marathon sessions, they are recorded and are available online. One big advantage of watching them in a recorded format is the ability to skip through the content rapidly instead of having to sit and wait for the whole process to unwind. The first day can be found here and the second here

The live, online Internet broadcast chalked up about 770 views on the first day. On the second day, only about 550 were reported.  The numbers seem low to this writer based on the intense, emotional interest on the part of many patients. Industry also does not seem overly interested despite forecasts of the billions of dollars to be made from regenerative medicine, which may say something about the likelihood of handsome profits.

Only 15 written comments have been filed so far, mostly from patients. That number is likely to increase as industry and academia weigh in with more details. 

The FDA has not released a timetable for action which could affect many of the 570 unregulated stem cell clinics operating across the country. 

The hearings generated almost no media coverage. However, the Washington Post and Stat published good pieces (see here and here) that provided an overview of the issues ahead of this week's hearing. You can find coverage by the California Stem Cell Report here, here, here and here.

California Healthline carried a piece Monday with comments from Mills that basically summarized his presentation to the FDA. Today, the agency's blog carried an item with the text of the Healthline comments. The item by Kevin McCormack, senior director of communications, also said that Mills believes that "the rules the FDA is proposing will not fix the problem, and may even make it worse."

UC Davis stem cell researcher Paul Knoepfler summed up the second day of the hearings in a blog item yesterday. He quoted Leigh Turner, a University of Minnesota bioethicist, as saying, 
“The out-of-control marketplace for stem cell interventions needs effective regulatory oversight. I therefore hope the draft guidances are more than stage props and this hearing is more than public theater. When patient safety and public health are at stake, the FDA must do more than function as a paper tiger. It is time for action.”
Here is a link to the key Federal Register document laying out the process. Here is a link to the site for filing a comment electronically.

The Wright Brothers, the Blind and Stem Cells: A Different Look at the FDA Hearing on More Regulation

A California stem cell researcher has filed a report that chronicles some of the details that help to provide a sharper picture of the events yesterday and today at 9000 Rockville Pike in Bethesda, Maryland.

Writing on The Niche blog, Jeanne Loring, head of the stem cell program at the Scripps Insitute, covered matters -- ranging from aircraft flight to the blind -- that came up at the Food and Drug Administration hearing into new regulation of stem cell therapies. .

Loring is at the hearing, which is underway again this morning, and will testify later today. Her item noted that the marathon yesterday included 42 presentations of five minutes each.

She wrote,
"The question asked by the FDA is 'what should we regulate?' and the answer from the majority of speakers was 'don’t regulate the things that we’re doing!'"
Loring continued,
"The clinics, in general, wanted the FDA to define the fat as having non-structural as well as structural functions. This would allow them to isolate cells from fat and inject them into the bloodstream, a popular treatment at many clinics, without FDA oversight.
"There were amusing incidents, such as when Randy Mills (president of the California stem cell agency)  used a metaphor to describe the FDA regulating rapidly developing stem cell therapies; it was, he said, as if the Wright brothers had just gotten their plane off the ground, and returned to find an FAA official who explained that he was going to regulate their planes. I also liked Arnold Caplan’s 'apology' for naming the stromal cells he extracted from bone marrow 40 years ago 'mesenchymal stem cells.' They aren’t stem cells, he said, but rather cells that secrete factors that may be useful for healing in some cases.
"At the periphery there were the victims of reckless stem cell clinics. A man wore a sign that said he was blinded by a stem cell procedure. A woman I met while standing in line for the bathroom told me that her husband and 6 others had been blinded at a Florida clinic. In his case, she said, he did not sign the paperwork that would prevent him from suing the clinic, so they’ve found a lawyer."
Loring predicted that today's session will include much from unregulated clinics. She said,
"From the applause (yesterday) whenever a speaker said they should not be regulated, I expect that most will be glowing. But I hope, for balance, that a few will report negative experiences. I haven’t decided what to say when my time comes (this) afternoon."

California's Randy Mills: Flood of Demand for Stem Cell Therapies Requires New Development Pathways

The president of the $3 billion California stem cell agency today told federal regulators that patient demand is "very real" for stem cell therapies and called for "alternative" pathways for development.

Randy Mills at FDA hearing
Randy Mills said patients are "really suffering and their needs are not being met." He said the demand is like a flood of water and will find its way around any blockages that rise up.

Mills spoke during the first day of a two-day hearing by the Food and Drug Administration(FDA) into possible new regulation of the stem cell field.

The session came as the Washington Post published online a lengthy piece about unregulated stem cell therapies and the increasing scrutiny they are facing from regulators. Reporter Laurie McGinley wrote about a clinic in Beverly Hills with a self-described "Time Machine" box.

Mark Berman, who was described as the co-founder of the "biggest network of commercial stem cell clinics" in the country, processes stems cell through the box for a procedure that he says doesn't require FDA approval.

McGinley wrote,
"In mini-liposuction procedures, Berman extracts fat tissue from patients and puts it into the Time Machine box, where a centrifuge separates stem cells from fat. The cells are then injected back into the patients to supposedly treat a variety of health problems, such as arthritic knees, heart disease, amyotrophic lateral sclerosis and even autism."
The treatments run about $8,900 each. Berman said his network has treated about 5,000 persons, McGinley reported.

The Post piece said that such treatments and their regulation or lack of regulation has "ignited a fierce debate among physicians, patients, scientists and politicians about whether the (FDA) should crack down on therapies that critics deride as snake oil but that some patients swear by. And it is fueling a broader, longer-term debate over how cellular therapies should be regulated."

Stem cell researcher Paul Knoepfler of UC Davis , who is quoted in the Washington Post article, took in today's FDA hearing from his lab in California. Writing on his blog, he delivered some "take-homes" after the session concluded. Here are a few excerpts from what Knoepfler wrote.
  • "Some speakers advocated for a 'middle ground' between 'nothing' in the way of regulation for instance of the dubious clinics and the perceived 'mountainous' extreme of the current FDA oversight system. The middle ground was, for example, argued for by Janet Marchibroda of the BPC and then also in the next talk by CIRM President Randy Mills. Mills, who is a very powerful speaker, argued that there is a harmful binary system now and we need a middle ground between the extremes of little-to-no regulation and the current in his view constricted pathway."
  • "Several speakers invoked patient autonomy and patient rights, and argued that they are doing what they are doing as practitioners of stem cell therapies simply for the betterment of patients. There’s the pesky problem there with this argument of probably millions of dollars in profit being made from the patients by some clinics though. If it’s all about patients, I challenge the clinics to do the transplants strictly 'at cost' with no profit margin."
  • "Many parties asked the FDA for more clarity and consistency on oversight. Also, a number of speakers asked for concrete, real world examples of how definitions would apply.  I’ve been pushing the FDA for increased clarity for years including lay abstract summaries of their main guidelines and statements of current thinking. I really like the idea of flowcharts."

Industry Seeks More Clarity on Proposed Federal Stem Cell Research Rules

The nation's leading industry group for regenerative medicine today called for a clearer federal pathway to help bring stem cell products to the marketplace. 

The Alliance for Regenerative Medicine (ARM), which has 240 business, academic and patient advocacy members, testified today at a Food and Drug Administration hearing into proposals for more regulation of the stem cell industry. Randy Mills, president of the California stem cell agency, is scheduled to speak later today.

In remarks prepared for delivery, Michael Werner, executive director of the group, said,
"What all manufacturers have in common...is that they seek a clear and predictable regulatory pathway to market. In general, ARM believes that while the draft guidances are a positive step forward, they still leave some questions unanswered regarding interpretation of regulations . Consequently, ARM believes that when FDA finalizes these guidances, it should take actions to provide even more clarity."
Werner went on to make specific suggestions for more explanation on  requirements for product characterization and associated claims for each type of product.

The full text of his remarks can be found here.  You can find additional information in the texts of the group's comments that were submitted in writing  on "minimal manipulation" here and and on "homologous use" here.

The two-day hearing is being broadcast live on the Internet.

Live on the Internet: Today's FDA Hearing on Stem Cell Regulation, Preview of California's Comments

The FDA's two-day hearing into stem cell treatments is underway this morning and can be seen live on the Internet, including a presentation this afternoon by the California stem cell agency, which is seeking to ease FDA regulation of stem cell clinical trials.

A likely preview of the comments from the agency popped up this morning on California Healthline in a piece by Emily Bazar. She carried the brief text of an interview with Randy Mills, president of the $3 billion California agency.

He said,
"The problem with (the FDA's current) strategy is twofold. It doesn’t address the patients, or the need side of the equation. And I don’t think it has a chance of actually working because the FDA will acknowledge that they do not have the resources to enforce these types of regulations at the clinic level.
"They would have to be essentially regulating the practice of physicians, which is well beyond their capabilities. Even if they were able to enforce it, it would just drive these patients somewhere else.
"We’re advocating for the creation of some middle pathway that would bring essentially unregulated therapies into the regulatory fold, but in a manner which could be complied with.
"I would rather know these clinics are being regulated and collecting data than have them operating under the radar screen of the FDA. I would like there to be a formal pre-market review of these therapies before they’re put on the market. I would like there to be safety and efficacy data.
"I’m going to try hard to get the FDA to see that just plugging this hole won’t make the problem go away."
Bazar's piece also contained the text of comments from Jeanne Loring, head of the stem cell research program at the Scripps Institute in La Jolla. She said,
"There’s no scientific evidence that the fat cells (unregulated) clinics are using are going to do the patient any good. And there’s no evidence that shows they are safe.
"I’m a stem cell scientist. I need scientific evidence before I will believe anything. Regulation will help determine the efficacy and safety of those fat cells.
"There are several lawsuits or potential lawsuits brewing over these stem cell treatments. People were promised they would get improvements and didn’t. And there are cases where people were actually harmed by stem cells.
"Some people truly believe they have been helped by the stem cell injections. I’m not going to argue with them. It’s a very personal and emotional response. It’s not something that can be scientifically validated. People are really desperate, especially really sick people and their families.
"That means patients are at risk. That’s what bothers me a lot. There’s nothing we can do to talk somebody out of going to a clinic if they feel that’s the only option they have. We just want to make sure nobody gets hurt. We also don’t want people to go broke. These treatments are not covered by insurance and they cost tens of thousands of dollars."

Here is a link to the actual broadcast, which is being watched by about 300 persons at this moment. An overview of the audience seems to indicate that it is being lightly attended. Mills is scheduled to speak at 4:23 p.m. EDT.

Here is a link to the agenda including a list of speakers and schedule. The broadcast also has closed caption capability.

Center for Genetics and Society Calls Trounson Affair Scandalous

The Center for Genetics and Society, a longtime critic of the California stem cell agency, yesterday described the Trounson-StemCells, Inc., affair as "scandalous" and part of an "object lesson" in how not to set up a state agency.

Writing on center's blog, Pete Shanks referred to the disclosure that Alan Trounson, former president of the $3 billion research effort, had received $443,500 in total compensation from StemCells, Inc., of Newark, Ca., for his work on the company's board over a two-year period. Trounson was appointed seven days after leaving the agency, which came as an unpleasant surprise to the stem cell agency's governing board.

StemCells, Inc., was awarded $40 million while Trounson was president of the California Institute for Regenerative Medicine (CIRM), as the agency is formally known.

Shanks, an author and consultant to the Berkeley-based center, said,
"Did Trounson or StemCells Inc. do anything illegal? Quite likely not. Was this transaction appropriate? Absolutely not! It’s scandalous, but it’s the kind of scandal that was built into CIRM from its very inception."
Shanks recounted the conflict-of-interest issues that have troubled the agency even prior to voter approval of the program. He concluded,
"CIRM is now slowly running out of the $3 billion of public funds allocated to it in 2004, and is expected to wind up in 2020. It has provided an object lesson in how not to set up and run an independent public-funded agency. These latest revelations should end any speculation about extending its charter."

Text of Irv Weissman's Comments Re Trounson Compensation

Stanford University stem cell researcher Irv Weissman has sent along the following comment in the wake of the publication of the Sept. 2, 2016, story concerning Alan Trounson's compensation from StemCells, Inc., a company co-founded by Weissman, who also served on its board of directors.
"I would like to correct some information that can be verified by CIRM officials and employees. I have known Alan Trounson for years before he came to CIRM both as a scientist and once on a fishing trip. After he got settled into his position at CIRM we met socially, and agreed to go on another fishing trip together. From that time forward he recused himself on all grants and CIRM related activities that involved either my lab or Stem Cells Inc. This was unfortunate for me, as there were times when he was the field expert and could have suggested appropriate reviewers, or mistakes in review, for grants coming from me at Stanford or Stem Cells, Inc. Although you mention the many successes we have had with CIRM grants, there were many more times when I failed to reach a funding score that was sufficient, sometimes with what I thought were inaccurate reviews,and sometimes with reviewers that I would have asked to be removed for conflicts outside of scientific expertise. I am happy to answer any questions on these issues for all grants on which I am a principal investigator, or as on the stem cell genomics grant, a participating but minor investigator who was the only person with purified stem and progenitor cells.
"I hope you dig into the actual current value of his or my stock, so that the public will know the real numbers. At least up to the wind-down of the company I believe I have never sold stock I hold, as I felt I always could have had information not generally available to the public, even when it was legal by SEC standards. In the early days of the company I contributed personal money to the company for stock so that the company could meet its payroll, and also I never sold those stocks. All of my SCI stocks are worth no more than and probably much less than 10% of that single contribution."

Alan Trounson, Former CEO of California Stem Cell Agency, Later Received $443,500 in Total Compensation from StemCells, Inc.

Text of Trounson Comments Re Compensation from StemCells, Inc.

Here is the text of Alan Trounson's email comments concerning the total compensation he received from StemCells, Inc., for service on its board. Trounson made the comments in response to an inquiry by the California Stem Cell Report regarding the matter and conflict of interest issues. The query did not involve reimbursement of travel expenses.
" I don't know what you think the conflict of interest is - I was cleared by independent legal advice by CIRM and no conflict was found by a Californian Government investigation. I was paid Directors fees and travel expenses to attend Board meetings. Do you expect me not to be reimbursed for travel and sitting as a Board Director? The share values are unknown - perhaps worth nothing. I actually pay monthly fees to hold them. I am no longer a Director of Stem Cells Inc and do not know what will happen to the shares. Stem Cells Inc has advised you the $ you quote for my reimbursement is inaccurate.
"Alan Trounson PhD
"Emeritus Professor"
The California Stem Cell Report followed up with an additional question regarding the matter and the state investigation. Trounson replied,
"Stem Cells Inc has told you exactly what I was paid and the state of the shareholding. You ought to do your own investigations into the Cal Government investigations and report like any reasonable journalist. The CIRM review was not 'limited' - external legal advice confirmed internal advice." 

Text of StemCells, Inc., Comments on Trounson Compensation

Here is the text of remarks from Ken Stratton, president of StemCells, Inc., concerning the $443,500 in total compensation from the company to Alan Trounson.
"As stated in our SEC filings, Dr. Trounson was paid total cash compensation of $59,550 for the years 2014 and 2015, consistent with board practice. He has also been provided stock awards which were to vest over time. Dr. Trounson currently owns fewer than 20,000 shares of our common stock and to my knowledge, he has never sold any of his shares. His unvested equity awards will not continue to vest now that he has resigned from the board in connection with the Microbot deal."

Good Safety News in Asterias California Stem Cell Trial


Jake Javier and family -- Javier family photo
For 18-year-old Jake Javier, it's a small matter of 10 million stem cells. And hope.

Javier is one of the patients in a clinical trial backed by $14.3 million from California's stem cell agency, which announced today some good news about the safety of that research.

For Javier, however, the details about "efficacy cohorts" and "AST-OPC1were a little more personal. The former high school football player is paralyzed from the chest down as the result of a swimming pool accident in June on the eve of his high school graduation.

Today he is one of a handful of patients enrolled in the spinal cord clinical trial by Asterias Biotherapeutics of Menlo Park, Ca., which picked up the human embryonic stem cell trial after it was abandoned by Geron in 2011.

The $3 billion stem cell agency announced today that Asterias "has cleared two key safety hurdles and been given approval to expand the therapy to a larger group of patients with a much higher dose of cells."

The next step is to insert 20 million stem cells into patients, up from the 10 million that Javier received.

Javier, who played football at San Ramon Valley High School, has been the subject of widespread media attention and fund-raising, including considerable reporting by San Francisco Bay Area television station KTVU.

Writing today on the stem cell agency's blog, The Stem Cellar, Kevin McCormack, senior director for communications, said,
"For people like Jake Javier this news is not about numbers or data, it’s personal. Earlier this summer Jake broke his neck at a pool party, celebrating graduating from high school. It left him paralyzed from the chest down with extremely limited use of his arms and hands. On July 7th Jake was enrolled in the Asterias trial, and had ten million cells transplanted into his neck.
"It could be months, even as much as one year, before we know if those cells are having any beneficial effect on Jake. But at least for now we know they don’t seem to be having any negative effects."
McCormack wrote,
“Our focus is always on the patient, so making sure a potential therapy is safe is an important first step,” says C. Randal Mills, Ph.D., the President and CEO of CIRM. “I recently met with Jake Javier, a young man who was treated in this trial, and heard first-hand what he and his family are going through in the aftermath of his injury. But I also saw a young man with remarkable courage and determination. It is because of Jake, and the others who volunteer to take part in clinical trials, that progress is possible. They are true heroes.”

'Unnerved' Researchers and Proliferation of Stem Cell Clinics: The Perspective from Los Angeles Times

The Los Angeles Times this past weekend picked up on the growing concern about the spread of dubious stem cell clinics triggered in many ways by a first-ever study by a UC Davis stem cell researcher. 

Pulitzer Prize-winning columnist Michael Hiltzik wrote,
"The proliferation of clinics nationwide offering stem cell therapies unnerves many researchers, who fear that unrealistic public expectations could undermine their own credibility. Patients with hard-to-treat conditions such as multiple sclerosis and Parkinson’s are easy marks who can be led to forgo established therapies in favor of unproven ones."
The headline on Hiltzik's piece said,
"These new stem cell treatments are expensive — and unproven"
Hiltzik interviewed a California lawyer who is working in the field. Hiltzik wrote,
"'Stem cell scientists include the best and the brightest doing great work, and I admire them,' says Janice Mulligan, a San Diego attorney currently assembling evidence for a potential class-action lawsuit against unnamed stem cell clinics. "At the other end of the scale, there’s snake oil.'"
Hiltzik also spoke to Paul Knoepfler, the UC Davis researcher who co-authored the study about stem cell clinics with Leigh Turner of the University of Minnesota. Hiltzik wrote,
"In an article just published in Stem Cells Translational Medicine, Knoepfler described his visit to one informational seminar sponsored by a clinic pitching a $5,999 stem cell treatment to about 30 attendees. Each was given a pack of forms to fill out, including a credit application. The spiel, he reported, featured personal anecdotes and 'questionable medical claims' — including the assertion that '90% of patients had a 50% or better improvement.'"

Odds for a Stem Cell Cure vs. Odds on Trump Winning the Election

The article explored one particular search for a cure for diabetes, but the headline was bleak.
"Will Embryonic Stem Cells Ever Cure Anything?"
The question came at the top of a piece by Aleszu Bajak in the Aug. 12, 2016, edition of the MIT Technology Review. 

Bajak quoted Doug Melton of Harvard as saying,
“The public definitely doesn’t appreciate that much of science is failure.”
Bajak, a veteran science writer and journalism instructor, continued with his own conclusion, 
"In fact, no field of biotechnology has promised more and delivered less in the way of treatments than embryonic stem cells." 
Hard, hard language that probably disturbs many in the field, including some at the California stem cell agency, which was founded on the promise of therapies from human embryonic stem cells(hESC). The agency has committed more than $2 billion to stem cell research since 2005 and is still looking for its first big score.

One can argue the fairness of the conclusion by Bajak, but it certainly seems tied to the excessive rhetoric that has surrounded the hESC field, particularly the $34 million ballot campaign that created the $3 billion state stem cell agency in 2004.

The rhetoric of the campaign came with a price. The agency is scheduled to run out of cash for new grants in 2020. Whether it can deliver on the campaign promises of 2004 will in large part determine whether it can conjure up additional funding.

The likeliest prospects for success today can be found in the list of clinical trials the agency is helping to fund and the scores of additional trials that it plans to assist in the next several years. They include efforts to deal with afflictions ranging from heart disease to diabetes.

By one widely cited measure, only one out of 10 conventional therapies entering clinical trials reaches the market place. Those are slim odds, ones that do not involve novel stem cell efforts, which are presumably more difficult. To put it another way, Donald Trump has better chances -- as of this writing -- of being elected president than of a clinical trial producing a stem cell cure.

Trump, however, is only going to have one chance. The California stem cell agency is expecting to take more than 50 shots at a therapy via its involvement in clinical trials over the next several years.

Nonetheless, it is a risky business, as venture capitalist Gregory Bonfiglio, pointed out to the California Stem Cell Report last December.  He said,
“There are risks inherent in the development of new, disruptive technology. The bigger risk is failing to deliver on their underlying promise to bring new regenerative therapies to patients…. The bigger risk is not doing anything.”

Digging into the 'Stem Cell Hard Sell:' Researcher Ventures Into 'Lion's Den'

A California stem cell researcher went "semi-undercover" recently and attended a commercial "educational seminar" that promoted stem cell treatments and handed out requests for credit information from those attending.

Paul Knoepfler of UC Davis recorded his experience at the session in an article this week in the Stem Cells Translational Medicine, which was founded in 2011 with $600,000 from the California stem cell agency.

Knoepfler did not identify the stem cell clinic that conducted the session. He said he wanted instead to be able to use a "higher degree of frankness" in writing about the session. Knoepfler noted, however, that he was quickly spotted by one of the organizers, some of whom lurked around him during the session. Knoepfler wrote on his blog Monday, 
"It was an intense experience and one where I felt at risk. To some extent it is akin to  going into the lion’s den. I didn’t know what reaction I would get if I were recognized by those running the seminar, which in fact did happen. They did not seem happy at all that I was there even though I wasn’t disruptive in the least. I had hoped to ask a few questions from my place in the audience, but the format did not allow it. Still I wondered if I could be kicked out. That didn’t happen."
The clinic involved is one of at least 570 across the country. Earlier this summer, Knoepfler and Leigh Turner, a University of Minnesota bioethicist, were the first to report on the scope of what passes for the commercial stem cell clinic industry in the United States when they documented the existence of those clinics.

About 30 people attended the session Knoepfler was at, including some who obviously had "serious medical conditions." He wrote,
"The seminar team (mostly dressed in medical scrubs) handed out a clipboard to each attendee with three pieces of paper very much like those that one might be given on arriving at a new doctor's office. We were told to fill in our information and then to return the sheets back to them before we left. Notably, the top sheet was a credit application. On another page, the clinic asked for extensive personal information, including name, age, birthdate, address, e-mail and phone number. Additional questions asked about medical conditions, as well as medical tests that had already been conducted." 
Knoepfler said several medical claims were made during the meeting including that the treatments had no side effects, were safer than the normal standard of care, did not pose immune rejection problems, were federally approved and were specifically effective for arthritis and pain.

The price of the treatment was $5,999 but attendees could get $1,000 off "if you sign up today at the seminar." Attendees were told that the clinic was heavily booked already with a one to two month waiting period.

In the piece about his foray into the "lion's den," Knoepfler wrote,
“Given the growing realization that there are hundreds of stem cell clinics in the U.S. today in 2016 and the observation that many hold recruitment seminars, it is possible that thousands of members of the public each year are attending infomercial seminars that provide misleading or even outright factually incorrect information about stem cells and questionable medical claims. This could not only lead many patients to receive unnecessary, unsafe or ineffectual treatments, but it may also contribute to public confusion about stem cells and the field of stem cell clinical research. These seminars represent only one type of an assortment of recruitment methods, including Internet, radio, newspaper, and television ads for various clinics, which may also contain dubious statements. I believe that such stem cell clinic marketing poses a significant threat to public perception and understanding of the legitimate stem cell translational medicine field.”

Pigs and People: Growing Human Organs in Animals, Changes at the Federal Level

Last week's news that the federal government is moving to lift its ban on funding research involving human-animal hybrids is a bit of old hat in California.

The state's $3 billion stem agency has long been okay with such research and has well-established protocols to ensure that it is conducted ethically and safely.

Last year, the agency, formally known as California Institute for Regenerative Medicine (CIRM), reported (see below) on its activities to the National Institutes of Health, declaring,
"CIRM has reviewed twelve protocols at seven different institutions where stem cells or neural progenitor cells were introduced into vertebrate animals. CIRM found that all protocols were reviewed and approved by a SCRO(standards review) committee consistent with CIRM requirements."

The announcement that the NIH is once again likely to fund the creation of chimeras -- organisms composed of genetically different cells -- received a significant amount of attention in the media. But none of the stories noted the origin of the word in Greek mythology, where it signified a fire-breathing female monster with a lion's head, a goat's body and a serpent's tail.

Sara Reardon of Nature wrote,
"Chimeras are a growing area of research. Currently, researchers use them to study early embryonic development and to create animal models of human diseases. But one major goal is to engineer animals to grow human organs. The organs could later be harvested from the adult animal and used for transplantation into a patient."
Kevin McCormack, senior director of communications for CIRM, told the California Stem Cell Report, last April,
"On a purely theoretical level CIRM has no objection to growing replacement organs or tissues in pigs, provided it met all CIRM’s rules and regulations. We fund research that does that all the time with mice and rats. Right now none of the research we fund is being used to do that."

Lenny Bernstein wrote in the Washington Post that researcher Shen Ding at the J. David Gladstone Institutes in San Francisco and who has received $6.7 million in research funding from CIRM, sounded a note of caution.
"While he does not favor the current (NIH) moratorium, Ding said, he believes scientists in this field must move slowly because 'we don't know how to precisely control where and how [cells] might contribute' to different organs."
Bernstein noted,
"The NIH imposed its temporary ban on funding last September, citing ethical concerns. These include worries over animals whose brains might contain human brain cells and what might happen if chimeras were able — and allowed — to reproduce."
The NIH is accepting comments over the next several weeks and then is expected to move forward with its proposal, perhaps with changes.

For Hank Greely, a Stanford law professor, it's about time. Last spring, he wrote an op-ed piece in the Los Angeles Times and said, 
"Today we face the possibility of babies getting organs grown in human/nonhuman chimeras — beasts that are pigs except for a single human organ. To the uninitiated, this may sound more like the dark arts than modern medicine, but pursuing careful research and potential clinical use of these chimeras is both proper and important."

The Human Egg Business: More Media Coverage of California Cash-for-Eggs Legislation

A renewed legislative effort in California to pay women for handing over their eggs for research is attracting more attention this year, including opposition from a former state senator sometimes called the mother of the state's stem cell agency.

Deborah Ortiz, former chair of the California Senate Health Committee, wrote an op-ed piece published this week in The Sacramento Bee. She noted that the stem cell agency prohibits paying women for their eggs. Ortiz wrote,
"I oppose AB 2531 (the number of the bill) on a number of grounds: First, we have very limited information on the long-term health effects of the egg retrieval process. Second, women who undergo egg retrieval are not research subjects in the traditional sense, as proponents assert. Finally, paying for women’s eggs for research purposes contradicts well-established national recommendations and state policy."
She continued,
"This is not an issue of equity with other research subjects. Women providing eggs for research are not comparable to research subjects in clinical trials. Their role is providing raw materials for pre-clinical research, rather than participating as subjects in medical research. And they are not afforded the safeguards or follow-up of subjects in clinical trials.
"Finally, AB 2531 conflicts with national recommendations and with policies in our state constitution. The 2010 guidelines of the National Academy of Science recommend that no payments beyond reimbursement for expenses be made for donating eggs for research."
Ortiz has been called the mother of the California Institute for Regenerative Medicine (CIRM), as the agency is formally known, because of her early role in support of stem cell research and authorship of an initial measure to use bond funding to finance it.

The cash-for-eggs bill also drew attention from Michael Hiltzik, a Pulitzer prize-winning columnist at the Los Angeles Times. He said that the measure should not be approved. Hiltzik wrote,
"There is scant research on the long-term health risks of egg retrieval, and nothing in the bill that would encourage more. To paper over that fact, the measure’s advocates have engaged in a neat bit of obfuscation. Assemblywoman Autumn Burke (D-Marina del Rey), who is carrying the bill for the ASRM, labels it a 'pay equity' bill....
"But it’s not about equity or discrimination. What worries the bill’s critics is that the measure may allow women to be misled into taking uninformed health risks by the prospect of easy cash."
The legislation surfaced at Buzzfeed in a piece by Cora Lewis and Azeen Ghorayshi. They quoted Sean Tipton, a spokesman for the fertility industry group, American Society for Reproductive Medicine (ASRM), that is sponsor of the legislation.
“'It’s (the bill is) needed to correct a strange and outdated feature in California law.'...Women are paid when they donate eggs to make babies, and people are paid when they are research subjects, he noted. 'But if you combine the two, you can’t be compensated. I don’t think that makes any sense,' Tipton said."
Another piece appeared on the Undark web site. It was written by Diane Tober, an assistant professor at UC San Francisco. She wrote,
"As a researcher myself, I can sympathize with the seduction of discovery, and the lure of developing new technologies and treatments that stem cell research may offer society at large. The millions of dollars of funding available to support such research would also be enticing.
"But the history demonstrates that the burden of human experimentation has rested on the shoulders of the socially and economically disadvantaged. The focus of AB-2531 is to obtain eggs for research, but it ignores the need for research into the impacts of the myriad drugs and procedures used to coax and extract those eggs in the first place." 
Leading the drive against the measure, vetoed by Gov. Jerry Brown in 2013, is the Center for Genetics and Society in Berkeley. It is circulating a flyer aimed at California lawmakers that says,
"This bill incentivizes invasive procedures that expose women to substantial short-term and unknown long-term health risks."
Brown has given no indication that he has changed his position on the measure.
