Hits and Myths as people celebrate Stem Cell Awareness Day

UC Davis #1

Stem Cell Awareness Day at UC Davis

Every year, the second Wednesday in October is set aside as Stem Cell Awareness Day, a time to celebrate the progress being made in the field and to remind us of the challenges that lie ahead.

While the event began here in California in 2008, with then-Governor Arnold Schwarzenegger highlighting the work of CIRM, saying: ”The discoveries being made today in our Golden State will have a great impact on many around the world for generations to come.” It has since grown to become a global event.

Here in California, for example, UC Davis and the University of Southern California (USC) both held events to mark the day.

At UC Davis Jan Nolta, PhD., the Director of the Stem Cell Program, introduced a series of speakers who highlighted the terrific work being done at the university. Peter Belafsky talked about using stem cells to repair damaged trachea and to help people who are experiencing voice or swallowing disorders. Mark Lee highlighted the progress being made in using stem cells to repair hard-to-heal broken bones. Aijun Wang focused on some really exciting work that could one day lead to a therapy for spina bifida (including some ridiculously cute video of English bulldogs who are able to walk again because of this therapy.)

USC hosted 100 local high school students for a panel presentation and discussion about careers in stem cell research. The panel featured four scientists talking about their experience, why the students should think about a career in science and how to go about planning one. USC put together a terrific video of the researchers talking about their experiences, something that can help any student around the US consider becoming part of the future of stem cell research.

Similar events were held in other institutions around California. But the celebration wasn’t limited to the Golden State. At the Texas Heart Institute in Houston, Texas, they held an event to talk to the public about the clinical trials they are supporting using stem cells to help people suffering from heart failure or other heart-related issues.

RegMedNet

Finally, the UK-based RegMedNet, a community site that unites the diverse regenerative medicine community, marked the day by exploring some of the myths and misconceptions still surrounding stem cells and stem cell research.

You can read those here.

Every group takes a different approach to celebrating Stem Cell Awareness Day, but each is united by a common desire, to help people understand the progress being made in finding new treatments and even cures for people with unmet medical needs.

California’s Stem Cell Agency Accelerates Treatments to Patients

The following article is an Op Ed that appeared in today’s print version of the San Francisco Chronicle

SanFranChronicle_Web

Biotechnology was born in California in the 1970s based on the discovery out of one of its universities and California is responsible for an industry that has impacted the lives of billions of people worldwide. In 2004, the voters of California approved Proposition 71, creating the California Institute for Regenerative Medicine and setting the state on the path to becoming a global leader in stem cell research. Today the therapies resulting from the institute’s work are not just changing lives, they are already saving lives.

Lives like Evie Vaccaro, who is alive today because of a treatment CIRM is funding. Vaccaro was born with SCID, also known as “bubble baby disease,” an immune disorder that often kills babies in their first two years. Vaccaro and dozens of other babies were given stem cell treatments thanks to the institute. All are showing improvement; some are now several years past treatment and considered cured.

An accident left Jake Javier from Danville paralyzed from the chest down on the eve of his high school graduation. Javier was treated in a CIRM-funded clinical trial. Today he has regained the use of his arms and hands, is driving a car and is a sophomore at Cal Poly San Luis Obispo. Five other patients treated at the same time as Javier have all experienced improvements meaning that instead of needing round-the-clock care, they can lead independent lives.

A study by the Tufts Center for the Study of Drug Development estimated it takes at least 10 years and $2.6 billion to develop one successful drug. In 14 years, and with just $3 billion, CIRM has funded 1,000 different projects, enrolled 900 patients, and supported 49 different clinical trials targeting diseases such as cancer, kidney failure and leukemia. Four of these programs have received an expedited designation by the U.S. Food and Drug Administration, meaning they could get faster approval to help more patients

We have created a network of world class medical clinics that have expertise in delivering treatments to patients. The CIRM Alpha Clinics offer treatments based on solid science, unlike the unlicensed clinics sprouting up around California that peddle unproven and potentially harmful therapies that cost patients thousands of dollars.

CIRM has:

  • Supported the creation of 12 stem-cell research facilities in California
  • Attracted hundreds of top-tier researchers to California
  • Trained a new generation of stem-cell scientists
  • Brought clinical trials to California — for example, one targeting ALS or Lou Gehrig’s disease
  • Deployed rigorous scientific standards and support so our programs have a “seal of approval” to attract $2.7 billion in additional investments from industry and other sources.

We recently have partnered with the National Institutes of Health to break down barriers and speed up the approval process to bring curative treatments to patients with Sickle Cell Disease.

Have we achieved all we wanted to? Of course not. The first decade of CIRM’s life was laying the groundwork, developing the knowledge and expertise and refining processes so that we can truly accelerate progress. As a leader in this burgeoning field of regenerative medicine, CIRM needs to continue its mission of accelerating stem-cell treatments to patients with unmet medical needs.

Dr. Maria T. Millan is President and CEO and Jonathan Thomas, JD, PhD, is the Board Chairman of the California Institute of Regenerative Medicine. 

 

 

How small talk led to a big break; a summer internship at CIRM

At CIRM, California’s Stem Cell Agency, we are fortunate to work with some amazing people. This summer we added another name that list when Melissa Cairos joined us for an internship. Melissa is now on to the next part of her adventure, as a policy wonk in Washington DC., but before she left we asked her to write about her experiences, and thoughts after her time at the Stem Cell Agency.

Melissa

Melissa Cairos

In January of 2018, I had a casual conversation with a woman, whom I had never met before, at a high school basketball game. Through small talk about my studies in school and my career interests for the future, the woman suggested I may be interested in her work because it seemed to be aligned with what I wanted to do. Her work happened to be at CIRM and she happened to be Maria Millan, the President and CEO.

Interestingly, I had never heard of CIRM (the California Institute for Regenerative Medicine) and had limited knowledge of regenerative medicine. But, I had dedicated a semester in spring of 2015 to analyzing and lobbying for the 21st Century Cures Act. I engaged in that work because I believe in the importance of investing in, and expediting the regulatory process for, lifesaving medical innovations, so that they can be accessed faster by patients and at a lower cost. The 21st Century Cures Act has since become law and has created incredible opportunities for both CIRM and the entire field of regenerative medicine.

Since joining CIRM, I have been able to continue with similar work by analyzing legislation, policies and regulations that affect patients’ abilities to access regenerative medicine therapies and our grantees’ abilities to receive reimbursement for their therapies. Because the stem cell and gene therapies CIRM’s grantees are coming up with are so new and innovative, I quickly realized that the legislative, policy and regulatory solutions for them needed to reflect that innovative spirit.

Working alongside Geoff Lomax, (the Senior Officer for CIRM Strategic Infrastructures)  my manager and mentor, we identified a number of potential barriers to access and reimbursement and tried to come up with policy solutions to address them.

For one project, we looked at the high cost of regenerative medicine therapies. Because high cost affects both patient access and potential reimbursement problems for the companies that develop those therapies we felt it was essential to try and come up with policy solutions to address these issues. To do this, we studied the traditional payment structure for drugs and medical devices and found it inappropriate for regenerative medicine in most cases.

This is because regenerative medicine requires a one-time high cost payment, but the regenerative medicine treatments/cures would eliminate long term costs including: previous treatment cost, complications from that treatment, progression of disease cost, hospitalizations, disability, quality of life, co-morbidities, disease effect on longevity etc. Thus, we proposed that payment models for regenerative medicine should consider their unique value benefits, such as the number of additional years of life the treatment added, and the overall cost-effectiveness of a one-time treatment compared to years of  treatment. With this in mind, we suggested innovative payment models that accounted for these factors and further proposed changes that need to be made so that different manufacturers and payors can engage in innovative financing agreements.

Through my work at CIRM, I found that what makes regenerative medicine unique is that it not only offers new ways of treating previously untreatable diseases, but it has additional benefits or value. Not only the economic value, but also the human value, as regenerative medicine offers patients with life threatening or painful chronic diseases a solution that will change their lives and the lives of their families for the better. Through this understanding, I grew an incredible appreciation for CIRM, for not only being a great place to work with incredibly talented and kind people, but also an incredibly unique government agency that reflected the value and innovative spirit of the research it supports.

I am so grateful that I met Maria at that basketball game and got the opportunity to support CIRM in adding value to California in my role this summer as a Policy Fellow. I plan to return to California in the future and work in the health policy field to further support programs, policies, and/or agencies, like CIRM, that bring so much value to this state.

 

 

Has Regenerative Medicine Come of Age?

Signals logo

For the past few years the Signals blog site –  which offers an insiders’ perspectives on the world of regenerative medicine and stem cell research – has hosted what it calls a “Blog Carnival”. This is an event where bloggers from across the stem cell field are invited to submit a piece based on a common theme. This year’s theme is “Has Regenerative Medicine Come of Age?” Here’s my take on that question:

Many cultures have different traditions to mark when a child comes of age. A bar mitzvah is a Jewish custom marking a boy reaching his 13th birthday when he is considered accountable for his own actions. Among Latinos in the US a quinceañera is the name given to the coming-of-age celebration on a girl’s 15th birthday.

Regenerative Medicine (RM) doesn’t have anything quite so simple or obvious, and yet the signs are strong that if RM hasn’t quite come of age, it’s not far off.

For example, look at our experience at the California Institute for Regenerative Medicine (CIRM). When we were created by the voters of California in 2004 the world of stem cell research was still at a relatively immature phase. In fact, CIRM was created just six years after scientists first discovered a way to derive stem cells from human embryos and develop those cells in the laboratory. No surprise then that in the first few years of our existence we devoted a lot of funding to building world class research facilities and investing in basic research, to gain a deeper understanding of stem cells, what they could do and how we could use them to develop therapies.

Fast forward 14 years and we now have funded 49 projects in clinical trials – everything from stroke and cancer to spinal cord injury and HIV/AIDS – and our early funding also helped another 11 projects get into clinical trials. Clearly the field has advanced dramatically.

In addition the FDA last year approved the first two CAR-T therapies – Kymriah and Yescarta – another indication that progress is being made at many levels.

But there is still a lot of work to do. Many of the trials we are funding at the Stem Cell Agency are either Phase 1 or 2 trials. We have only a few Phase 3 trials on our books, a pattern reflected in the wider RM field. For some projects the results are very encouraging – Dr. Gary Steinberg’s work at Stanford treating people recovering from a stroke is tremendously promising. For others, the results are disappointing. We have cancelled some projects because it was clear they were not going to meet their goals. That is to be expected. These clinical trials are experiments that are testing, often for the first time ever in people, a whole new way of treating disease. Failure comes with the territory.

As the number of projects moving out of the lab and into clinical trials increases so too are the other signs of progress in RM. We recently held a workshop bringing together researchers and regulators from all over the world to explore the biggest problems in manufacturing, including how you go from making a small batch of stem cells for a few patients in an early phase clinical trial to mass producing them for thousands, if not millions of patients. We are also working with the National Institutes of Health and other stakeholders in discussing the idea of reimbursement, figuring out who pays for these therapies so they are available to the patients who need them.

And as the field advances so too do the issues we have to deal with. The discovery of the gene-editing tool CRISPR has opened up all sorts of possible new ways of developing treatments for deadly diseases. But it has also opened up a Pandora’s box of ethical issues that the field as a whole is working hard to respond to.

These are clear signs of a maturing field. Five years ago, we dreamed of having these kinds of conversations. Now they are a regular feature of any RM conference.

The simple fact that we can pose a question asking if RM has come of age is a sign all by itself that we are on the way.

Like little kids sitting in the back of a car, anxious to get to their destination, we are asking “Are we there yet?” And as every parent in the front seat of their car responds, “Not yet. But soon.”

Stem cell therapy offers a glimpse of hope for a student battling a deadly cancer

“About a week later they gave me a call and mentioned the word ‘cancer’ to me. For a long time, I was depressed and then, I guess you accept it and try to make the most out of the time you have now.’

That is not something you expect to hear from a 24 year old. But for Daniel Apodaca that became, very suddenly, his reality. He was diagnosed with a rare, soft tissue cancer called epithelioid sarcoma. Fortunately for Daniel help was at hand, and a lot closer than he could ever have possibly anticipated.

Daniel is a student at UCLA. CIRM is funding a clinical trial run by UCLA’s Dr. Antoni Ribas that targets the same cancer Daniel is battling. The therapy re-programs a person’s own immune system to help fight the disease.

Daniel became patient #1 in that trial.

CNN reporter Rachel Crane profiled Dr. Ribas and the treatment he hopes will save Daniel’s life.

 

 

Research Targeting Prostate Cancer Gets Almost $4 Million Support from CIRM

Prostate cancer

A program hoping to supercharge a patient’s own immune system cells to attack and kill a treatment resistant form of prostate cancer was today awarded $3.99 million by the governing Board of the California Institute for Regenerative Medicine (CIRM)

In the U.S., prostate cancer is the second most common cause of cancer deaths in men.  An estimated 170,000 new cases are diagnosed each year and over 29,000 deaths are estimated in 2018.  Early stage prostate cancer is usually managed by surgery, radiation and/or hormone therapy. However, for men diagnosed with castrate-resistant metastatic prostate cancer (CRPC) these treatments often fail to work and the disease eventually proves fatal.

Poseida Therapeutics will be funded by CIRM to develop genetically engineered chimeric antigen receptor T cells (CAR-T) to treat metastatic CRPC. In cancer, there is a breakdown in the natural ability of immune T-cells to survey the body and recognize, bind to and kill cancerous cells. Poseida is engineering T cells and T memory stem cells to express a chimeric antigen receptor that arms these cells to more efficiently target, bind to and destroy the cancer cell. Millions of these cells are then grown in the laboratory and then re-infused into the patient. The CAR-T memory stem cells have the potential to persist long-term and kill residual cancer calls.

“This is a promising approach to an incurable disease where patients have few options,” says Maria T. Millan, M.D., President and CEO of CIRM. “The use of chimeric antigen receptor engineered T cells has led to impressive results in blood malignancies and a natural extension of this promising approach is to tackle currently untreatable solid malignancies, such as castrate resistant metastatic prostate cancer. CIRM is pleased to partner on this program and to add it to its portfolio that involves CAR T memory stem cells.”

Poseida Therapeutics plans to use the funding to complete the late-stage testing needed to apply to the Food and Drug Administration for the go-ahead to start a clinical trial in people.

Quest Awards

The CIRM Board also voted to approve investing $10 million for eight projects under its Discovery Quest Program. The Quest program promotes the discovery of promising new stem cell-based technologies that will be ready to move to the next level, the translational category, within two years, with an ultimate goal of improving patient care.

Among those approved for funding are:

  • Eric Adler at UC San Diego is using genetically modified blood stem cells to treat Danon Disease, a rare and fatal condition that affects the heart
  • Li Gan at the Gladstone Institutes will use induced pluripotent stem cells to develop a therapy for a familial form of dementia
  • Saul Priceman at City of Hope will use CAR-T therapy to develop a treatment for recurrent ovarian cancer

Because the amount of funding for the recommended applications exceeded the money set aside, the Application Subcommittee voted to approve partial funding for two projects, DISC2-11192 and DISC2-11109 and to recommend, at the next full Board meeting in October, that the projects get the remainder of the funds needed to complete their research.

The successful applications are:

Can stem cells help people recovering from a stroke? You asked, and the experts answered

FacebookLive_AskExperts_Stroke_IMG_1656

We recently held our first ever Facebook Live event. It was focused on the use of stem cells and recovery from a stroke and featured three great guests: Dr. Gary Steinberg, chief of Neurosurgery at Stanford, Sonia Coontz, a patient of Dr. Steinberg’s, and CIRM’s own Science Officer Dr. Lila Collins.

We had an amazing response from people during the event and in the days since then with some 6,750 people watching the video and almost 1,000 people reacting by posting a comment or sharing it with friends. It was one of the most successful things we have ever done on Facebook so it’s not surprising that we plan on doing many more Facebook Live ‘Ask the Expert’ events in the future. We will post more details of that as we finalize them.

We tried to cover as many topics as possible during the hour but there were simply too many questions for us to get to all of them. So here is a recap of the key issues we covered, and a few we didn’t have a chance to answer.

Let’s start with Dr. Steinberg’s explanation of the research that led to his current clinical trial:

Dr. Steinberg: “I got interested in this about 18 years ago when I took human cells and transplanted them into rodent models of stroke. What we found was that when we transplanted those cells into the stroke region, the core of the stroke, they didn’t survive very well but when we moved them a few millimeters away from the stroke they not only survived but they migrated to the stroke.

The reason they migrate is that the stem cells have receptors on them that interact with chemicals given off by the stroke environment and that’s why they migrate to the stroke site. And when they get to the site they can turn into different kinds of cells. Very importantly we found these mice and rats that had behavioral problems – walking, moving – as a result of the stroke, we found we could improve their neurological outcomes with the stem cells.

With the help of CIRM, which has been very generous, we were fortunate enough to receive about $24 million in funding over the last 8 years, from 2010, to move this therapy into the clinic to understand the basic mechanisms of the recovery and to start clinical trials

One of the surprising things was that our initial notion was that the cells we transplanted into the brains would initially turn into the cells in the brain affected by the stroke and reconstitute those circuits. We were shocked to find that that was not what was happening, that only a few of the transplanted cells turned into neurons. The way they were recovering function was by secreting very powerful growth factors and molecules and proteins that enhanced native recovery or the ability of the normal brain to recover itself. Some of these processes included outgrowth of neurons, new connections, new synapses, not from the stem cells but from the native cells already in the brain.

This is not cell replacement but enhancing native recovery and, in a simple sense, what the cells are doing, we believe, is to change the adult brain, which has a hard time recovering from a stroke, into an infant brain and infants recover very well after a stroke.”

All this work was focused on ischemic strokes, where a blockage cuts off blood flow to the brain. But people like Cheryl Ward wanted to know: “Will this work for hemorrhagic stroke?” That’s where a blood vessel in the brain leaks or ruptures.

Dr. Steinberg: “I suspect we will be generalizing this therapy into hemorrhagic patients very, very soon and there’s no reason why it shouldn’t work there. The reason we didn’t start there is that 85% of strokes are ischemic and only 15% are hemorrhagic so it’s a smaller population but a very, very important population because when patients have a hemorrhage from a stroke they are often more seriously disabled than from ischemic.”

Dr. Lila Collins: “I would like to highlight one trial for hemorrhagic stroke with the Mayo Clinic and that’s using mesenchymal stem cells (normally found in bone marrow or blood). It’s an early stage, Phase 1 safety study in patients with recent cerebral hemorrhage.  They are looking at improvements in neurological function and patients have to be treated within 72 hours after the stroke.”

Dr. Steinberg explained that because it’s more difficult to enroll patients within 72 hours of a stroke that we may end up offering a combination of therapies spread out over months or even years.

Dr. Steinberg: “It may be that and we may figure this out in the next 5 to 10 years, that you might want to treat patients acutely (right away) with an intravenous therapy in the first 72 hours and then you might want to come in again sub-acutely within a few months, injecting the cells into the brain near the stroke, and then maybe come in chronically a few years later if there are still problems and place the cells directly in the brain. So, lots of ways to think about how to use this in the future.”

James Russell suffered a stroke in 2014 and wrote:

“My left side was affected. My vision was also impacted. Are any stroke patients being given stem cells seeing possible improvement in visual neglect?”

Dr. Steinberg: “We don’t know the answer to that yet, it’s quite possible. It’s true these vision circuits are not dead and could be resurrected. We have not targeted visual pathways in our work, we have targeted motor functions, but I would also be optimistic that we could target patients who have vision problems from stroke. It’s a very important area.

A number of people wondered if stem cells can help people recovering from a stroke can they also help people with other neurological conditions.

Hanifa Gaphoor asked “What about Parkinson’s disease?” and Ginnievive Patch wondered “Do you feel hopeful for neurological illnesses like Huntington’s disease and ALS? Dr. Steinberg was cautiously optimistic.

Dr. Steinberg: “We’ve extended this kind of treatment not just for ischemic stroke but into traumatic brain injury (TBI) and we just completed a trial for patients with chronic TBI or who have suffered a trauma to the brain. Many other indications may be possible. In fact, now that we know these circuits are not dead or irreversibly injured, we believe we could even extend this to neurodegenerative diseases like ALS, Parkinson’s, maybe even to Alzheimer’s disease in the future. So, lots of hope but we don’t want to oversell this, and we want to make sure this is done in a rigorous fashion.”

Several people had questions about using their own adipose, or fat stem cells, in therapies being offered at clinics around the US and in other countries. Cheri Hicks asked: “I’m curious if adipose stem cell being used at clinics at various places is helpful or beneficial?”

Dr. Steinberg: “I get emails or calls from patients every week saying should I go to Russia, India or Mexico and get stem cell transplants which are done not as part of a rigorous trial and I discourage patients from getting stem cells that are not being given in a controlled fashion. For one thing, patients have been getting hurt by these treatments in these clinics; they have developed tumors and infections and other problems. In many cases we don’t even know what the cells are, there’s not published information and the patients pay cash for this, of course.”

At CIRM we also worry about people going to clinics, in the US and in other countries, where they are getting therapies that have not been approved by the US Food and Drug Administration (FDA) or other appropriate regulatory bodies. That’s why we have created this page on our website to help people who want a stem cell therapy but don’t know what to look for in a clinical trial or what questions to ask to make sure it’s a legitimate trial, one that’s been given the go-ahead by the FDA.

Bret Ryan asked: “What becomes of the implanted cells?”

Dr. Steinberg: We found after transplanting the cells, one week after the transplant, we see a new abnormality in the premotor cortex, the area of the brain that controls motor function. We saw a new abnormality there or a new signal that disappears after a month and never comes back. But the size of that temporary abnormality after one week correlates very closely with the degree of recovery after six months, one year and two years.

One of the interesting things is that it doesn’t seem to be necessary for the cells to survive long term to have beneficial effects. The cells we used in the SanBio trial don’t survive more than a month and yet they seem to aid recovery function in our pilot studies which is sustained for years.”

And of course, many people, such as Karen Smart, wanted to know how they could get the therapy. Right now, the clinical trial is fully enrolled but Stanford is putting together a waiting list for future trials. If you are interested and would like more information, please email: stemcellstudy@stanford.edu.

Sonia Coontz, the patient who was also a key part of the Facebook Live event, has an amazing story to tell. She was left devastated, physically and emotionally, after having a stroke. But then she heard about Dr. Steinberg’s clinical trial and it changed her life. Here’s her story.

We were thrilled to receive all of your comments and questions during our first Facebook Live event. It’s this kind of dialogue between scientists, patients and the public that will be critical for the continued support of our mission to accelerate stem cell treatments to patients with unmet medical needs.

Due to the response, we plan to regularly schedule these “Ask the Expert” events. What disease area would you like us to focus on next time? Leave us a comment or email info@cirm.ca.gov

 

Stem Cell Roundup: Jake Javier’s amazing spirit; TV report highlights clinic offering unproven stem cell therapies

In the Roundup we usually focus on studies that highlight advances in stem cell research but today we’re going to do something a little different. Instead of relying on print for our stories, we’re turning to video.

We begin with a piece about Jake Javier. Regular readers of our blog will remember that Jake is the young man who broke his neck the day before he graduated high school, leaving him paralyzed from the upper chest down.

After enrolling in the CIRM-funded Asterias clinical trial, and receiving a transplant of 10 million stem cells, Jake regained enough use of his arms and hands to be able to go to Cal Poly and start his life over.

This video highlights the struggles and challenges he faced in his first year, and his extraordinary spirit in overcoming them.

(thanks to Matt Yoon and his Creative Services team at Cal Poly for this video)

Going Undercover

The second video is from the NBC7 TV station in San Diego and highlights one of the big problems in regenerative medicine today, clinics offering unproven therapies. The investigative team at NBC7 went undercover at a stem cell clinic seminar where presenters talked about “the most significant breakthrough in natural medicine” for improving mobility and reducing pain. As the reporter discovered, the reality didn’t live up to the promise.

Using biological “codes” to generate neurons in a dish

BrainWavesInvestigators at the Scripps Research Institute are making brain waves in the field of neuroscience. Until now, neuroscience research has largely relied on a variety of animal models to understand the complexities of various brain or neuronal diseases. While beneficial for many reasons, animal models do not always allow scientists to understand the precise mechanism of neuronal dysfunction, and studies done in animals can often be difficult to translate to humans. The work done by Kristin Baldwin’s group, however, is revolutionizing this field by trying to re-create this complexity in a dish.

One of the primary hurdles that scientists have had to overcome in studying neuronal diseases, is the impressive diversity of neuronal cell types that exist. The exact number of neuronal subtypes is unknown, but scientists estimate the number to be in the hundreds.

While neurons have many similarities, such as the ability to receive and send information via chemical cues, they are also distinctly specialized. For example, some neurons are involved in sensing the external environment, whereas others may be involved in helping our muscles move. Effective medical treatment for neuronal diseases is contingent on scientists being able to understand how and why specific neuronal subtypes do not function properly.

In a study in the journal Nature, partially funded by CIRM, the scientists used pairs of transcription factors (proteins that affect gene expression and cell identity), to turn skin stem cells into neurons. These cells both physically looked like neurons and exhibited characteristic neuronal properties, such as action potential generation (the ability to conduct electrical impulses). Surprisingly, the team also found that they were able to generate neurons that had unique and specialized features based on the transcription factors pairs used.

The ability to create neuronal diversity using this method indicates that this protocol could be used to recapitulate neuronal diversity outside of the body. In a press release, Dr. Baldwin states:

KristinBaldwin

Kristin Baldwin, PhD

“Now we can be better genome detectives. Building up a database of these codes [transcription factors] and the types of neurons they produce can help us directly link genomic studies of human brain disease to a molecular understanding of what goes wrong with neurons, which is the key to finding and targeting treatments.”

These findings provide an exciting and promising tool to more effectively study the complexities of neuronal disease. The investigators of this study have made their results available on a free platform called BioGPS in the hopes that multiple labs will delve into the wealth of information they have opened up. Hopefully, this system will lead to more rapid drug discovery for disease like autism and Alzheimer’s

CIRM applauds FDA crackdown on stem cell clinics that “peddle unapproved treatments.”

FDA

CIRM is commending the US Food and Drug Administration (FDA) for its action against two stem cell clinics offering unapproved therapies.

On Wednesday, the FDA filed two complaints in federal court seeking a permanent injunction against California Stem Cell Treatment Center Inc. and US Stem Cell Clinic LLC. of Sunrise, Florida. The FDA says the clinics are marketing stem cell products without FDA approval and are not complying with current good manufacturing practice requirements.

“We strongly support the FDA’s strong stance to seek judicial action to stop these  clinics from marketing unproven therapies that pose a threat to the safety of patients” says Maria T. Millan, M.D., CIRM’s President and CEO. “We agree with FDA Commissioner Dr. Scott Gottlieb’s statement that these ‘bad actors leverage the scientific promise of this field to peddle unapproved treatments that put patients’ health at risk.’”

In his statement yesterday, Dr. Gottlieb denounced the clinics saying they are exploiting patients and causing some of them “serious and permanent harm.”

“In the two cases filed today, the clinics and their leadership have continued to disregard the law and more importantly, patient safety. We cannot allow unproven products that exploit the hope of patients and their loved ones. We support sound, scientific research and regulation of cell-based regenerative medicine, and the FDA has advanced a comprehensive policy framework to promote the approval of regenerative medicine products. But at the same time, the FDA will continue to take enforcement actions against clinics that abuse the trust of patients and endanger their health.”

At CIRM, we believe it is critically important for participants in stem cell treatments to be fully informed about the nature of the therapy they are receiving, including whether it is approved by the FDA. Last year we partnered with California State Senator Ed Hernandez to pass Senate Bill No. 512, which required all clinics offering unproven stem cell therapies to post notices warning patients they were getting a therapy that was not approved by the FDA.

The Stem Cell Agency has taken several other actions to protect people seeking legitimate stem cell therapies.

  • All the clinical trials we consider for funding must already have an active Investigational New Drug (IND) status with the FDA and go through a rigorous scientific review by leading experts.
  • All CIRM-funded trials must adhere to strict regulatory standards and safety monitoring.
  • We have created the CIRM Alpha Stem Cell Clinics, a network of six top California medical centers that specialize in delivering patient-centered stem cell clinical trials that meet the highest standards of care and research.
  • CIRM provides access to information on all the clinical trials it supports.

“Through its funding mechanism, active partnership and infrastructure programs, CIRM has shepherded 48 FDA regulated, scientifically sound, rigorously reviewed promising stem cell and regenerative medicine projects into clinical trials,” says Dr. Millan. “Some of these treatment protocols have already started to show preliminary signs of benefit for debilitating and life-threatening disorders. We are committed to doing all we can, in partnership with patients, the research community and with the FDA, to develop transformative treatments for patients with unmet medical needs while adhering to the highest standards to protect the health and safety of patients and the public.”

To help people make informed decisions we have created an infographic and video that detail the information people need to know, and the questions they should ask, before they agree to participate in a clinical trial or get a stem cell therapy.
