We are at a turning point in regenerative medicine as the first wave of treatments have obtained FDA approval. But at the same time as we see the advance of scientifically rigorous research and regulated products we are also witnessing the continued proliferation of “unproven treatments.” This dueling environment can be overwhelming and distracting to individuals and families trying to manage life-threatening diseases.
How does a patient navigate this environment and get trusted and reliable information to help sort through their options?
CIRM teamed up with the CURA Foundation to organize a roundtable discussion intended to answer this question. The conversation included thought leaders involved in patient advocacy, therapy research and development, public policy and research funding. The roundtable was divided into three segments designed to discuss:
Examples of state-of-the-art patient navigation systems,
Policy, research and infrastructure needs required to expand navigation systems, and
Communication needs for engaging patients and the broader community.
Examples of Navigation Systems:
This session was framed around the observation that patients often do not get the best medicines or treatments available for their condition. For example, in the area of cancer care there is evidence that the top 25% of cancers are not being treated optimally. Historic barriers to optimal treatment include cost pressures that may block access to treatments, lack of knowledge about the available treatments or the absence of experts in the location where the patient is being treated. Much of the session focused on how these barriers are being overcome by partnerships between health care provides, employers and patients.
For example, new technologies such as DNA sequencing and other cell-based markers enable better diagnosis of a patient’s underlying disease. This information can be collected by a community hospital and shared with experts who work with the treating doctor to consider the best options for the patient. If patients need to access a specialty center for treatment, there are new models for the delivery of such care. Emphasis is placed on building a relationship with the patient and their family by surrounding them with a team that can address any questions that arise. The model of patient-centered care is being embraced by employers who are purchasing suites of services for their employees.
Patient advocacy groups have also supported efforts to get the best information about the patients’ underlying disease. Advocacy organizations have been building tools to connect patients with researchers with the aim of allowing secure and responsible sharing of medical information to drive the patient-centered development of new treatments. In a related initiative, the American Society of Hematology is creating a data hub for clinical trials for sickle cell disease. Collectively, these efforts are designed to accelerate new treatments by allowing critical data to be shared among researchers.
Essential Policy Infrastructure for Regenerative Medicine:
Session two dovetailed nicely with first discussion. There was continued emphasis on the need for additional evidence (data) to demonstrate that regenerative medicine treatments are having a significant effect on the patient’s disease. Various speakers echoed the need for patients in clinical trials to work with researchers to determine the benefits of treatments. Success stories with gene therapies in blood diseases were cited as proof of concept where treatments being evaluated in clinical trials are demonstrating a significant and sustained impact on diseases. Evidence of benefit is needed by both regulatory bodies that approve the treatments, such as the FDA, and by public and private payers / insurers that pay for treatments and patients that need to know the best option for their particular disease.
In addition, various speakers cited the continued proliferation of “unproven treatments” being marketed by for-profit centers. There was broad concern that the promotion of treatment where there is no evidence of effectiveness will mislead some patients and potentially harm the scientifically rigorous development of new treatments. Particularly for “stem cell” treatments, there was a desire to develop evaluation criteria that are clear and transparent to allow legitimate treatments to be distinguished from those with no evidence of effectiveness. One participant suggested there be a scorecard approach where specific treatments could be rated against specific indicators of safety, medical benefit and value in relation to alternative treatments. The idea would be to make this information widely available to patients, medical providers and the public to inform everything from medical decision making to advertising.
Communicating the Vision
The final session considered communication needs for the field of regenerative medicine. Patients and patient advocacy organizations described how they are using social media and other networking tools to share information and experiences in navigating their treatment options. Patient advocacy groups also described the challenges from providers of unproven treatments. In one case, a for profit “pop up” clinic had used the group’s videos in an attempt to legitimize their unproven treatment.
There was general consensus among the panelists that the field of regenerative medicine needs “trusted intermediaries” who can evaluate claims and help patients distinguish between high quality research and “snake oil”. These intermediaries should have the capacity to compile the most reliable evidence and utilize it to determine what options are available to patients. In addition, there needs to be shared decision making model where patients have the opportunity to explore options in an unbiased environment so they may make the best decision based on their specific needs and values.
Creating this kind of Navigation System will not be easy but the alternative is unacceptable. Too many vulnerable patients are being taken advantage of by the growing number of “predatory clinics” hawking expensive therapies that are both unproven and unapproved. We owe it to these patients to create a simple way for them to identify what are the most promising therapies, ones that have the highest chance of being both safe and effective. The roundtable discussion marked a starting point, bringing together many of the key players in the field, highlighting the key issues and beginning to identify possible solutions.
CIRM funds a lot of research and all of it has life-saving potential. But every once in a while you come across a story about someone benefiting from CIRM-supported research that highlights why the work we do is so important. This story is about a brilliant researcher at UC San Diego developing a treatment for a really rare disease, one that was unlikely to get funding from a big pharmaceutical company because it offered little chance for a return on its investment. At CIRM we don’t have to worry about things like that. Stories like this are our return on investment.
Our thanks to our colleagues at UCSD News for allowing us to run this piece in full.
By Heather Buschman, PhD
Born with a rare disease called cystinosis, 20-year-old Jordan Janz arrived at a crossroads: continue life as-is, toward a future most likely leading to kidney failure and an early death or become the first patient in the world to undergo a new gene-and-stem cell therapy developed over more than a decade by UC San Diego School of Medicine researchers
For the majority of Jordan Janz’s 20 years of life, most neighbors in his tiny Canadian town never knew he was sick. Janz snowboarded, hunted and fished. He hung with friends, often playing ice hockey video games. He worked in shipping and receiving for a company that makes oil pumps.
But there were times when Janz was younger that he vomited up to 13 times each day. He received a growth hormone injection every day for six years. He needed to swallow 56 pills every day just to manage his symptoms. And the medication required around-the-clock administration, which meant his mother or another family member had to get up with him every night.
“I was tired for school every day,” Janz said. “I was held back in second grade because I missed so much school. And because the medication had a bad odor to it, when I did go to school kids would ask, ‘What’s that smell?’ It was hard.”
Janz was born with cystinosis, a rare metabolic disorder that’s detected in approximately one in 100,000 live births worldwide. People with cystinosis inherit a mutation in the gene that encodes a protein called cystinosin. Cystinosin normally helps cells transport the amino acid cystine. Because cells in people with cystinosis don’t produce the cystinosin protein, cystine accumulates. Over the years, cystine crystals build up and begin to damage tissues and organs, from the kidneys and liver to muscles, eyes and brain. Numerous symptoms and adverse consequences result.
These days, Janz manages his condition. There’s a time-release version of the symptom-relieving medication now that allows him to go 12 hours between doses, allowing for a good night’s sleep. But there’s no stopping the relentless accumulation of cystine crystals, no cure for cystinosis.
In October 2019, Janz became the first patient to receive treatment as part of a Phase I/II clinical trial to test the safety and efficacy of a unique gene therapy approach to treating cystinosis. The treatment was developed over more than a decade of research by Stephanie Cherqui, PhD, associate professor of pediatrics, and her team at University of California San Diego School of Medicine.
“The day they started looking for people for the trial, my mom picked up the phone, found a number for Dr. Cherqui, called her and put my name in as a candidate,” Janz said.
Janz’s mom, Barb Kulyk, has long followed Cherqui’s work. Like many parents of children with cystinosis, Kulyk has attended conferences, read up on research and met many other families, doctors and scientists working on the condition. Kulyk says she trusts Cherqui completely. But she was understandably nervous for her son to be the first person ever to undergo a completely new therapy.
“It’s like giving birth,” she said shortly before Janz received his gene therapy. “You’re really looking forward to the outcome, but dreading the process.”
Cherqui’s gene therapy approach involves genetical modifying the patient’s own stem cells. To do this, her team obtained hematopoietic stem cells from Janz’s bone marrow. These stem cells are the precursors to all blood cells, including both red blood cells and immune cells. The scientists then re-engineered Janz’s stem cells in a lab using gene therapy techniques to introduce a normal version of the cystinosin gene. Lastly, they reinfused Janz with his own now-cystinosin-producing cells. The approach is akin to a bone marrow transplant — the patient is both donor and recipient.
“A bone marrow transplant can be very risky, especially when you take hematopoietic stem cells from a another person. In that case, there’s always the chance the donor’s immune cells will attack the recipient’s organs, so-called graft-versus-host disease,” Cherqui explained. “It’s a great advantage to use the patient’s own stem cells.”
As is the case for other bone marrow transplants, Janz’s gene-modified stem cells are expected to embed themselves in his bone marrow, where they should divide and differentiate to all types of blood cells. Those cells are then expected to circulate throughout his body and embed in his tissues and organs, where they should produce the normal cystinosin protein. Based on Cherqui’s preclinical data, she expects the cystinosin protein will be transferred to the surrounding diseased cells. At that point, Janz’s cells should finally be able to appropriately transport cystine for disposal — potentially alleviating his symptoms.
Before receiving his modified stem cells, Janz had to undergo chemotherapy to make space in his bone marrow for the new cells. Not unexpectedly, Janz experienced a handful of temporary chemotherapy-associated side-effects, including immune suppression, hair loss and fatigue. He also had mucositis, an inflammation of mucous membranes lining the digestive tract, which meant he couldn’t talk or eat much for a few days.
Now, only three months after his transfusion of engineered stem cells, Cherqui reports that Janz is making a good recovery, though it’s still too early to see a decrease in his cystinosis-related symptoms.
“I’ve been sleeping at least 10 hours a day for the last few weeks,” Janz said. “It’s crazy, but I know my body is just working hard to, I guess, create a new ‘me.’ So it’s no wonder I’m tired. But I’m feeling okay overall.
“One of the hardest parts for me is being inactive for so long. I’m not used to doing nothing all day. But I’m taking an online course while I wait for my immune system to rebuild. And I’m getting pretty good at video games.”
Like all Phase I/II clinical trials, the current study is designed to first test the safety and tolerability of the new treatment. Janz knows the treatment might not necessarily help him.
“When we started this trial, my mom explained it like this: ‘We have a tornado at the front door and a tsunami at the back door, and we have to pick one to go through. Neither will be any fun and we don’t know what’s going to happen, but you have to believe you will make it and go.
“So we weighed the pros and cons and, basically, if I don’t do this trial now, when I’m older I might not be healthy and strong enough for it. So I decided to go for it because, even if there are consequences from the chemotherapy, if it works I could live 20 years longer than I’m supposed to and be healthy for the rest of my life. That’s worth it.”
Besides the possible benefit to himself, Janz also sees his participation in the clinical trial as a way to contribute to the tight-knit community of families with children who have cystinosis.
“I’m willing to do if it helps the kids,” he said. “Somebody has to do it. I don’t have the money to donate to scientific conferences and stuff like that, but I can do this trial.”
If the treatment continues to meet certain criteria for safety and efficacy for Janz and one other participant after three months, two more adult participants will be enrolled. Three months after that, if the treatment continues to be safe and effective, the trial might enroll two adolescent participants. To participate in the clinical trial, individuals must meet specific eligibility requirements.
Later in the trial, Cherqui and team will begin measuring how well the treatment actually works. The specific objectives include assessing the degree to which gene-modified stem cells establish themselves in bone marrow, how they affect cystine levels and cystine crystal counts in blood and tissues.
“This trial is the first to use gene-modified hematopoietic stem cell gene therapy to treat a multi-organ degenerative disorder for which the protein is anchored in the membrane of the lysosomes, as opposed to secreted enzymes,” Cherqui said. “We were amazed when we tested this approach in the mouse model of cystinosis — autologous stem cell transplantation reversed the disease. The tissues remained healthy, even the kidneys and the eyes.”
Trial participants are closely monitored for the first 100 days after treatment, then tested again at six, nine, 12, 18 and 24 months post-gene therapy for a variety of factors, including vital signs, cystine levels in a number of organs, kidney function, hormone function and physical well-being.
“If successful in clinical trials, this approach could provide a one-time, lifelong therapy that may prevent the need for kidney transplantation and long-term complications caused by cystine buildup,” Cherqui said.
For the trial participants, all of the pre-treatment tests, the treatment itself, and monitoring afterward means a lot of travel to and long stays in San Diego.
It’s tough on Kulyk and Janz. They have to fly in from Alberta, Canada and stay in a San Diego hotel for weeks at a time. Kulyk has two older adult children, as well as a 12-year-old and a seven-year-old at home.
“I’ve missed a lot of things with my other kids, but none of them seem to hold any grudges,” she said. “They seem to be totally fine and accepting. They’re like, ‘We’re fine, mom. You go and take care of Jordan.’”
Janz is looking forward to getting back home to his friends, his dog and his job, which provided him with paid leave while he received treatment and recovers.
For Cherqui, the search for a cystinosis cure is more than just a scientific exercise. Cherqui began working on cystinosis as a graduate student more than 20 years ago. At the time, she said, it was simply a model in which to study genetics and gene therapy.
“When you read about cystinosis, it’s just words. You don’t put a face to it. But after I met all the families, met the kids, and now that I’ve seen many of them grow up, and some of them die of the disease — now it’s a personal fight, and they are my family too.”
Patients with cystinosis typically experience kidney failure in their 20s, requiring kidney dialysis or transplantation for survival. For those born with cystinosis who make it into adulthood, the average lifespan is approximately 28 years old.
“I’m optimistic about this trial because it’s something we’ve worked so hard for and now it’s actually happening, and these families have so much hope for a better treatment,” Cherqui said. “After all the years of painstaking laboratory research, we now need to move into the clinic. If this works, it will be wonderful. If it doesn’t, we will all be disappointed but a least we’ll be able to say we tried.”
Nancy Stack, who founded the Cystinosis Research Foundation after her own daughter, Natalie, was diagnosed with the disease, calls Cherqui “the rock star of our community.”
“She cares deeply about the patients and is always available to talk, to explain her work and to give us hope,” Stack said. “She said years ago that she would never give up until she found the cure — and now we are closer to a cure than ever before.” (Read more about Natalie here.)
In addition to cystinosis, Cherqui says this type of gene therapy approach could also lead to treatment advancements for other multi-organ degenerative disorders, such as Friedreich’s ataxia and Danon disease, as well as other kidney, genetic and systemic diseases similar to cystinosis.
While they wait for the long-term results of the treatment, Kulyk is cautiously hopeful.
“Moms are used to being able to fix everything for their children — kiss boo-boos make them better, make cupcakes for school, whip up Halloween costumes out of scraps, pull a coveted toy out of thin air when it has been sold out for months.
“But we have not been able to fix this, to take it away. I not only want this disease gone for my child, I want cystinosis to be nothing more than a memory for all the children and adults living with it. I know that even if and when Jordan is cured, there will still be so much work to do, in terms of regulatory approvals and insurance coverage.
“Having hope for your child’s disease to be cured is a slippery slope. We have all been there, held hope in our hands and had to let go. But, I find myself in a familiar place, holding onto hope again and this time I am not letting go.”

Cherqui’s research has been funded by the Cystinosis Research Foundation, California Institute for Regenerative Medicine (CIRM), and National Institutes of Health. She receives additional support from the Sanford Stem Cell Clinical Center and CIRM-funded Alpha Stem Cell Clinic at UC San Diego Health, and AVROBIO.
There are a growing number of predatory clinics in California and around the US, offering unproven stem cell therapies. For patients seeking a legitimate therapy it can often be hard finding a reliable clinic, one offering treatments based on the rigorous science required in a clinical trial sanctioned by the US Food and Drug Administration (FDA). That’s one of the reasons why the California Institute for Regenerative Medicine (CIRM) created the CIRM Alpha Stem Cell Clinic Network and we are delighted the clinics have now been chosen as a Core program of the American Society of Hematology (ASH) Sickle Cell Disease (SCD) Collaborative Trials Network.
The Alpha Clinics are a network of top California medical centers that specialize in delivering stem cell clinical trials to patients. It consists of five leading medical centers throughout California: City of Hope, University of California (UC) San Diego, UC Irvine & UC Los Angeles, UC Davis and UC San Francisco.
The mission of the ASH Research Collaborative SCD Clinical Trials Network is to improve outcomes for individuals with Sickle Cell Disease by promoting innovation in therapy development and clinical trial research.
“The key to finding a cure for this crippling disease, and finding it quickly, is to work together”, says Maria T. Millan, MD, President & CEO of CIRM. “That’s why we are delighted to be chosen as a core program for the ASH Sickle Cell Disease Clinical Trials Network. This partnership means we can share data and information about best practices to help us improve the quality of the research being done and the clinical care we can offer patients. We already have 23 clinical stage therapies in cell and gene therapy, including two clinical trials targeting SCD, so we feel we have a lot to bring to the partnership in terms of experience and expertise.”
Sickle Cell disease is a life-threatening blood disorder that affects 100,000 people, mostly African Americans, in the US. It is caused by a single genetic mutation that results in the production of “sickle” shaped red blood cells that can block blood vessels causing intense pain, recurrent hospitalization, multi-organ damage and strokes.
“We hear a lot about the moonshot for curing cancer, but a moonshot for curing sickle cell disease should also be possible. Sickle cell disease was the first genetic disease that was discovered, and wouldn’t it be great if it is also one of the first ones we can cure in everyone?”
It is hoped that creating this network of clinical trial sites across the US will better serve an historically under-served population.
Establishing links and educational materials across these sites can increase patient engagement and recruitment
Standardizing resources across the network can ensure efficiency and coordination
Improving the training of clinical research staff can promote patient safety and trust and increase research quality
The CIRM Alpha Clinics Network has a proven track record of creating a faster, more streamlined approach in running clinical trials. It has developed the tools and systems to simultaneously launch clinical trials at multiple sites; created model non-disclosure agreements to make it easier for clinical trial sponsors to sign up; created a system to enable one Institutional Review Board (IRB) to approve a trial to be carried out at multiple sites rather than requiring each site to have its own IRB approval; developed best practices to quickly share experience and expertise across the network; and set up a database of over 20 million Californians to improve patient recruitment.
An Executive Summary prepared for the Western States Sickle Cell Disease Clinical Trials Network said: “the ASCC provides a formidable clinical trial unit uniquely qualified to deliver the next generation of cell and gene therapy products for SCD.”
An independent Economic Impact Report says the California Institute for Regenerative Medicine (CIRM) has had a major impact on California’s economy, creating tens of thousands of new jobs, generating hundreds of millions of dollars in new taxes, and producing billions of dollars in additional revenue for the state.
The report, done by Dan Wei and Adam Rose at the Price School of Public Policy at the University of Southern California, looked at the impacts of CIRM funding on both the state and national economy from the start of the Stem Cell Agency in 2004 to the end of 2018.
The total impacts on the California economy are estimated
billion of additional gross output (sales revenue)
million of additional state/local tax revenues
million of additional federal tax revenues
additional full-time equivalent (FTE) jobs, half of which offer salaries
considerably higher than the state average
Millan, M.D., CIRM’s President and CEO, says the report reflects the Agency’s
role in building an ecosystem to accelerate the translation of important stem
cell science to solutions for patients with unmet medical needs. “CIRM’s
mission on behalf of patients has been the priority from day one, but this
report shows that CIRM funding brings additional benefits to the state. This report
reflects how CIRM is promoting economic growth in California by attracting
scientific talent and additional capital, and by creating an environment that
supports the development of businesses and commercial enterprises in the state”
In addition to the benefits to California, the impacts
outside of California on the US economy are estimated to be:
billion of additional gross output (sales revenue)
million of additional state (non-Californian) & local tax revenue
million of additional federal tax revenues
additional full-time equivalent (FTE) jobs
researchers summarize their findings, saying: “In terms of economic impacts, the
state’s investment in CIRM has paid handsome dividends in terms of output, employment,
and tax revenues for California.”
The estimates in the report are based on the economic stimulus
created by CIRM funding and by the co-funding that researchers and companies
were required to provide for clinical and late-stage preclinical projects. The
estimates also include:
Investments in CIRM-supported projects from private funders such
as equity investments, public offerings and mergers and acquisitions,
Follow-on funding from the National Institutes of Health and other
organizations due to data generated in CIRM-funded projects
Funding generated by clinical trials held at CIRM’s Alpha Stem
Cell Clinics network
researchers state “Nearly half of these impacts emanate from the $2.67 billion
CIRM grants themselves.”
economic impact of California’s investment in stem and regenerative cell
research is reflective of significant progress in this field that was just
being born at the time of CIRM’s creation,” says Dr. Millan. “We fund the most
promising projects based on rigorous science from basic research into clinical
trials. We partnered with researchers and companies to increase the likelihood
of success and created specialized infrastructure such as the Alpha Clinics
Network to support the highest quality of clinical care and research standards
for these novel approaches. The
ecosystem created by CIRM has attracted scientists, companies and capital from outside
the state to California. By supporting promising science projects early on,
long before most investors were ready to come aboard, we enabled our scientists
to make progress that positioned them to attract significant commercial
investments into their programs and into California.”
think one of the greatest strengths of CIRM has been their focus on development
of new stem cell therapies that can become real medicines,” says UCLA and
Orchard Therapeutics’ Don Kohn, M.D. “This has meant guiding academic
investigators to do the things that may be second nature in
industry/pharmaceutical companies but are not standard for basic or clinical
research. The support from CIRM to perform the studies and regulatory
activities needed to navigate therapies through the FDA and to form alliances
with biotech and pharma companies has allowed the stem cell gene therapy we
developed to treat SCID babies to be advanced and licensed to Orchard
Therapeutics who can make it available to patients across the country.”
support has been instrumental to our early successes and our ability to rapidly
progress Forty Seven’s CD47 antibody targeting approach with magrolimab,” says
Mark Chao, M.D., Ph.D., Founder and Vice President of Clinical Development at
Forty Seven Inc. “ CIRM was an early collaborator in our clinical
programs, and will continue to be a valued partner as we move forward with our
MDS/AML clinical trials.”
researchers say the money generated by partnerships and investments, what is
called “deal-flow funding”, is still growing and that the economic benefits
created by them are likely to continue for some time: “Deal-flow funding
usually involves several waves or rounds of capital infusion over many years,
and thus is it expected that CIRM’s past and current funding will attract
increasing amounts of industry investment and lead to additional spending
injections into the California economy in the years to come.”
They conclude their report by saying: “CIRM has led to
California stem cell research and development activities becoming a leader
among the states.”
At CIRM we are privileged to work with many remarkable people who combine brilliance, compassion and commitment to their search for new therapies to help people in need. One of those who certainly fits that description is UC Davis’ Jan Nolta.
This week the UC Davis Newsroom posted a great interview with Jan. Rather than try and summarize what she says I thought it would be better to let her talk for herself.
Talking research, unscrupulous clinics, and sustaining the momentum
In 2007, Jan Nolta
returned to Northern California from St. Louis to lead what was at the
time UC Davis’ brand-new stem cell program. As director of the UC Davis Stem Cell Program
and the Institute for Regenerative Cures, she has overseen the opening
of the institute, more than $140 million in research grants, and dozens
upon dozens of research studies. She recently sat down to answer some
questions about regenerative medicine and all the work taking place at UC Davis Health.
Q: Turning stem cells into cures has been your mission and mantra since you founded the program. Can you give us some examples of the most promising research?
I am so excited about our research. We have about 20 different disease-focused teams.
That includes physicians, nurses, health care staff, researchers and
faculty members, all working to go from the laboratory bench to
patient’s bedside with therapies.
Perhaps the most promising and
exciting research right now comes from combining blood-forming
stem cells with gene therapy. We’re working in about
eight areas right now, and the first cure, something that we definitely
can call a stem cell “cure,” is coming from this combined approach.
doctors will be able to prescribe this type of stem cell therapy.
Patients will use their own bone marrow or umbilical cord stem cells.
Teams such as ours, working in good manufacturing practice
facilities, will make vectors, essentially “biological delivery
vehicles,” carrying a good copy of the broken gene. They will be
reinserted into a patient’s cells and then infused back into the
patient, much like a bone marrow transplant.
“Perhaps the most promising and exciting research right now comes from combining blood-forming stem cells with gene therapy.”
Along with treating the famous bubble baby disease,
where I had started my career, this approach looks very promising for
sickle cell anemia. We’re hoping to use it to treat several different
inherited metabolic diseases. These are conditions characterized by an
abnormal build-up of toxic materials in the body’s cells. They interfere
with organ and brain function. It’s caused by just a single enzyme.
Using the combined stem cell gene therapy, we can effectively put a good
copy of the gene for that enzyme back into a patient’s bone marrow stem
cells. Then we do a bone marrow transplantation and bring back a
person’s normal functioning cells.
The beauty of this therapy is
that it can work for the lifetime of a patient. All of the blood cells
circulating in a person’s system would be repaired. It’s the number one
stem cell cure happening right now. Plus, it’s a therapy that won’t be
rejected. These are a patient’s own stem cells. It is just one type of
stem cell, and the first that’s being commercialized to change cells
throughout the body.
Q: Let’s step back for a moment. In 2004, voters approved Proposition 71.
It has funded a majority of the stem cell research here at UC Davis and
throughout California. What’s been the impact of that ballot measure
and how is it benefiting patients?
We have learned so
much about different types of stem cells, and which stem cell will be
most appropriate to treat each type of disease. That’s huge. We had to
first do that before being able to start actual stem cell therapies. CIRM [California Institute for Regenerative Medicine] has funded Alpha Stem Cell Clinics.
We have one of them here at UC Davis and there are only five in the
entire state. These are clinics where the patients can go for
high-quality clinical stem cell trials approved by the FDA
[U.S. Food and Drug Administration]. They don’t need to go to
“unapproved clinics” and spend a lot of money. And they actually
“By the end of this year, we’ll have 50 clinical trials.”
By the end of this year, we’ll have 50 clinical trials [here at UC Davis Health]. There are that many in the works.
Our Alpha Clinic
is right next to the hospital. It’s where we’ll be delivering a lot of
the immunotherapies, gene therapies and other treatments. In fact, I
might even get to personally deliver stem cells to the operating room
for a patient. It will be for a clinical trial involving people who have
broken their hip. It’s exciting because it feels full circle, from
working in the laboratory to bringing stem cells right to the patient’s
We have ongoing clinical trials
for critical limb ischemia, leukemia and, as I mentioned, sickle cell
disease. Our disease teams are conducting stem cell clinical trials
targeting sarcoma, cellular carcinoma, and treatments for dysphasia [a
swallowing disorder], retinopathy [eye condition], Duchenne muscular
dystrophy and HIV. It’s all in the works here at UC Davis Health.
also great potential for therapies to help with renal disease and
kidney transplants. The latter is really exciting because it’s like a
mini bone marrow transplant. A kidney recipient would also get some
blood-forming stem cells from the kidney donor so that they can better
accept the organ and not reject it. It’s a type of stem cell therapy
that could help address the burden of being on a lifelong regime of
immunosuppressant drugs after transplantation.
Q: You and
your colleagues get calls from family members and patients all the
time. They frequently ask about stem cell “miracle” cures. What should
people know about unproven treatments and unregulated stem cell clinics?
That’s a great question.The number one rule is that if
you’re asked to pay money for a stem cell treatment, don’t do it. It’s a
big red flag.
When it comes to advertised therapies: “The number one rule is that if you’re asked to pay money for a stem cell treatment, don’t do it. It’s a big red flag.”
there are unscrupulous people out there in “unapproved clinics” who
prey on desperate people. What they are delivering are probably not even
stem cells. They might inject you with your own fat cells, which
contain very few stem cells. Or they might use treatments that are not
matched to the patient and will be immediately rejected. That’s
dangerous. The FDA is shutting these unregulated clinics down one at a
time. But it’s like “whack-a-mole”: shut one down and another one pops
On the other hand, the Alpha Clinic is part of our
mission is to help the public get to the right therapy, treatment or
clinical trial. The big difference between those who make patients pay
huge sums of money for unregulated and unproven treatments and UC Davis
is that we’re actually using stem cells. We produce them in rigorously
regulated cleanroom facilities. They are certified to contain at least 99% stem cells.
and family members can always call us here. We can refer them to a
genuine and approved clinical trial. If you don’t get stem cells at the
beginning [of the clinical trial] because you’re part of the placebo
group, you can get them later. So it’s not risky. The placebo is just
saline. I know people are very, very desperate. But there are no miracle
cures…yet. Clinical trials, approved by the FDA, are the only way we’re
going to develop effective treatments and cures.
Scientific breakthroughs take a lot of patience and time. How do you and
your colleagues measure progress and stay motivated?
Motivation? “It’s all for the patients.”
all for the patients. There are not good therapies yet for many
disorders. But we’re developing them. Every day brings a triumph.
Measuring progress means treating a patient in a clinical trial, or
developing something in the laboratory, or getting FDA approval. The big
one will be getting biological license approval from the FDA, which
means a doctor can prescribe a stem cell or gene therapy treatment. Then
it can be covered by a patient’s health insurance.
I’m a cancer
survivor myself, and I’m also a heart patient. Our amazing team here at
UC Davis has kept me alive and in great health. So I understand it from
both sides. I understand the desperation of “Where do I go?” and “What
do I do right now?” questions. I also understand the science side of
things. Progress can feel very, very slow. But everything we do here at
the Institute for Regenerative Cures is done with patients in mind, and
We know that each day is so important when you’re watching
a loved one suffer. We attend patient events and are part of things
like Facebook groups, where people really pour their hearts out. We say
to ourselves, “Okay, we must work harder and faster.” That’s our
motivation: It’s all the patients and families that we’re going to help
who keep us working hard.
Here at CIRM, we get calls every day from patients asking us if there are any trials or therapies available to treat their illness or an illness affecting a loved one. Unfortunately, there are some predatory clinics that try to take advantage of this desperation by advertising unproven and unregulated treatments for a wide range of diseases such as Diabetes, Alzheimer’s, Parkinson’s, Amyotrophic Lateral Sclerosis (ALS), and Multiple Sclerosis (MS).
A recent article in the Los Angeles Times describes how one of these predatory stem cell clinics is in a class action lawsuit related to false advertising of 100% patient satisfaction. Patients were led to believe that this percentage was related to the effectiveness of the treatment, when in fact it had to do with satisfaction related to hospitality, hotel stay, and customer service. These kinds of deceptive tactics are commonplace for sham clinics and are used to convince people to pay tens of thousands of dollars for sham treatments.
how can a patient or loved one distinguish a legitimate clinical trial or
treatment from those being offered by predatory clinics? We have established
the “fundamental three R’s” to help in making this distinction.
United States Food and Drug Administration (FDA) has a regulated process
that it uses in evaluating potential treatments from researchers seeking
approval to test these in a clinical trial setting. This includes extensive reviews by scientific
peers in the community that are well informed on specific disease areas. Those
that adhere to these regulations get an FDA seal of approval and are subject to
extensive oversight to protect patients participating in this trial.
Additionally, these regulations ensure that the potential treatments are
properly evaluated for effectiveness. The 55 clinical trials
that we have currently funded as well as the clinical trials being conducted in our Alpha Stem Cell Clinic
Network all have this FDA seal of approval. In contrast to this,
the treatments offered at predatory clinics have not gone through the rigorous
standards necessary to obtain FDA approval.
We have partnered with reputable institutions to carry out the clinical trials we have funded and establish our Alpha Stem Cell Clinic Network. These are institutions that adhere to the highest scientific standards necessary to effectively evaluate potential treatments and communicate these results with extreme accuracy. These institutions have expert scientists, doctors, and nurses in the field and adhere to rigorous standards that have earned these institutions a positive reputation for carrying out their work. The sites for the Alpha Stem Cell Clinic Network include City of Hope, UCSF, UC San Diego, UCLA, UC Davis, and UC Irvine. In regards to the clinical trials we have directly funded, we have collaborated with other prestigious institutions such as Stanford and USC. All these institutions have a reputation for being respected by established societies and other professionals in the field. The reputation that predatory clinics have garnered from patients, scientists, and established doctors has been a negative one. An article published in The New York Times has described the tactics used by these predatory clinics as unethical and their therapies have often been shown to be ineffective.
The clinical trials we fund and those offered at our Alpha Stem Cell Clinic Network are reliable because they are trusted by patients, patient advocacy groups, and other experts in the field of regenerative medicine. A part of being reliable involves having extensive expertise and training to properly evaluate and administer treatments in a clinical trial setting. The doctors, nurses, and other experts involved in clinical trials given the go-ahead by the FDA have extensive training to carry out these trials. These credentialed specialists are able to administer high quality clinical care to patients. In a sharp contrast to this, an article published in Reuters showed that predatory clinics not only administer unapproved stem cell treatments to patients, but they use doctors that have not received training related to the services they provide.
you are looking at a potential clinical trial or treatment for yourself or a
loved one, just remember the 3 R’s we have laid out in this blog.
What do you do when the supposed solution to a problem actually turns out to be a part of the problem? That’s the situation facing people who want to direct patients to scientifically sound clinical trials. Turns out the site many were going to may be directing patients to therapies that are not only not scientifically sound, they may not even be safe.
The site in question
is the www.clinicaltrials.gov
website. That’s a list of all the clinical trials registered with the National
Institutes of Health. In theory that should be a rock-solid list of trials that
have been given the go-ahead by the Food and Drug Administration (FDA) to be tested
in people. Unfortunately, the reality is very different. Many of the trials
listed there have gone through the rigorous testing and approval process to
earn the right to be tested in people. But some haven’t. And figuring out which
is which is not easy.
The issue was highlighted by a terrific article on STAT News this week. The article’s title succinctly sums up the piece: “Stem cell clinics co-opt clinical-trials registry to market unproven therapies, critics say.”
The story highlights how clinics that are offering unproven and
unapproved stem cell therapies can register their “clinical trial” on the site,
even if they haven’t received FDA approval to carry out a clinical trial.
Leigh Turner, a bioethicist at the University of Minnesota and a long-time foe of these clinics, said:
“You can concoct this bogus appearance
of science, call it a clinical study, recruit people to pay to participate in
your study, and not only that: You can actually register on clinicaltrials.gov
and have the federal government help you promote what you’re doing. That struck
me as both dangerous and brilliant.”
At CIRM this is a problem we face almost every day. People call or email us asking for help finding a stem cell therapy for everything from cancer and autism to diabetes. If we are funding something or if there is one underway at one of our Alpha Stem Cell Clinics we can direct them to that particular trial. If not, the easiest thing would be to direct them to the clinicaltrials.gov site. But when you are not sure that all the programs listed are legitimate clinical trials, that’s not something we always feel comfortable doing.
As the STAT piece points out, some of the “trials” listed on the site
are even being run by companies that the FDA is trying to shut down because of
serious concerns about the “therapies” they are offering. One was for a Florida
clinic that had blinded four people. Despite that, the clinic’s projects remain
on the site where other patients can find them.
Being listed on clinicaltrials.gov gives clinics offering unproven therapies
an air or legitimacy. So how can you spot a good trial from a bad one? It’s not
One red flag is if the trial is asking you to pay for the treatment.
That’s considered unethical because it’s asking you to pay to be part of an
experiment. Only a very few legitimate clinical trials ask patients to pay, and
even then, only with permission from the FDA.
Another warning sign is anything that has a laundry list of things it
can treat, everything from arthritis to Alzheimer’s. Well-designed clinical
trials tend to be targeted at one condition not multiple ones.
We have put together some useful tools for patients considering taking
part in a clinical trial. Here is a link
to a video and infographic that tell people the questions they need to ask,
and things they need to consider, before signing up for any clinical trial.
So why does the NIH continue to allow these clinics to “advertise”
their programs on its website? One reason is that the NIH simply doesn’t have
the bandwidth to check every listing to make sure they are legit. They have
tried to make things better by including a warning, stating:
“Listing a study
does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for
details. Before participating in a study, talk to your health care provider and
learn about the risks
and potential benefits.”
The bottom line is
that if you are in the market for a stem cell therapy you should approach it
the way you would any potentially life-changing decision: caveat emptor, buyer
There’s a large body of research that shows that many people learn better through visuals. Studies show that much of the sensory cortex in our brain is devoted to vision so our brains use images rather than text to make sense of things.
That’s why we think it just makes sense to use visuals, as much as we can, when trying to help people understand advances in stem cell research. That’s precisely what our colleagues at U.C. San Diego are doing with a new show called “Stem Cell Science with Alysson Muotri”.
Alysson is a CIRM grantee
who is doing some exciting work in developing a deeper understanding of autism.
He’s also a really good communicator who can distill complex ideas down into
easy to understand language.
The show features Alysson,
plus other scientists at UCSD who are working hard to move the most promising
research out of the lab and into clinical trials in people. Appropriately the
first show in the series follows that path, exploring
how discoveries made using tiny Zebrafish could hopefully lead to stem cell
therapies targeting blood diseases like leukemia. This first show also highlights
the important role that CIRM’s Alpha Stem Cell Clinic Network will play in
bringing those therapies to patients.
You can find a sneak preview of the show on YouTube. The series proper will be broadcast on California local cable via the UCTV channel at 8:00 pm on Thursdays starting July 8, 2019.
And if you really
have a lot of time on your hands you can check out the more
than 300 videos CIRM has produced on every aspect of stem cell research
from cures for fatal diseases to questions to ask before taking part in a
When governments cut funding for scientific research the consequences can be swift, and painful. In Canada last week for example, the government of Ontario cut $5 million in annual funding for stem cell research, effectively ending a project developing a therapy to heal the damaged lungs of premature babies.
Here in the US the federal government is already placing restrictions on support for fetal tissue research and there is speculation embryonic stem cell research could be next. That’s why agencies like CIRM are so important. We don’t rely on a government giving us money every year. Instead, thanks to the voters of California, we have had a steady supply of funds to enable us to plan long-term and support multi-year projects.
But those funds
are due to run out soon. We anticipate funding our last new awards this year
and while we have enough money to continue supporting all the projects our
Board has already approved, we won’t be able to take on any new projects. That’s
bad news for the scientists and, ultimately, really bad for the patients who
are in need of new treatments for currently incurable diseases.
We are going to talk about that in two upcoming events.
The first is a
patient advocate event at UC San Diego

When CIRM was created in 2004 the field of stem cell research was still very much in its infancy. Fast forward 15 years and it’s moving ahead at a rapid pace, probably faster than most scientists would have predicted. How fast? Find out for yourself at a free public event at UC San Diego on May 28th from 12.30 to 1.30p.
In the last 15 years CIRM has funded 53 clinical
trials in everything from heart disease and stroke, to spinal cord injury,
vision loss, sickle cell disease and HIV/AIDS.
Clearly progress is being made. But the field is also facing some challenges. Funding at the federal level for stem cell research is under threat, and CIRM is entering what could be its final phase. We have enough money left to fund new projects through this year (and these are multi-year projects so they will run into 2021 or 2022) but unless there is a new round of funding we will slowly disappear. And with us, may also disappear the hopes of some of the most promising projects underway.
If CIRM goes, then projects that we have supported and nurtured through different phases of research may struggle to make it into a clinical trial because they can’t get the necessary funding.
Clearly this is a pivotal time in the field.
We will discuss all this, the past, the present and the uncertain future of stem cell research at the meeting at UC San Diego on May 28th. The doors will open at noon for registration (snacks and light refreshments will also be available) and the program runs from 12.30p to 1.30p.
The speakers are:
Jamieson, Director of the UC San Diego Health CIRM Alpha Stem Cell Clinic
and Sanford Stem Cell Clinical Center.
Millan, President and CEO of CIRM
Higgins, CIRM Board member and Patient Advocate for Parkinson’s Disease.
And of course, we want to hear from you, so we’ll leave
plenty of time for questions.
