In the time of coronavirus an awful lot of people are not just working from home they’re also working out at home. That’s a good thing; exercise is a great way to boost the immune system, stay healthy and deal with stress. But for people used to more structured workouts at the gym it can come with a downside. Trying new routines at home that look easy on YouTube, but are harder in practice could potentially increase the risk of injury.
A new study from Japan looks at what happens when you damage a muscle. It won’t help it heal faster, but it will at least let you understand what is happening inside your body as you sit there with ice on your arm and ibuprofen in your hand.
The researchers found that when you damage a muscle, for example by trying to lift too much weight or doing too many repetitions of one exercise, the damaged muscle fibers leak substances that activate nearby “satellite” stem cells. These satellite cells then flock to the site of the injury and help repair the muscle.
The team, from Kumamoto University and Nagasaki University in Japan, named the leaking substances “Damaged myofiber-derived factors” (DMDFs) – personally I think “Substances Leaked by Injured Muscles (SLIM) would be a much cooler acronym, but that’s just me. Gaining a deeper understanding of how DMDFs work might help lead to therapies for older people who have fewer satellite muscle cells, and also for conditions like muscular dystrophy and age-related muscular fragility (sarcopenia), where the number and function of satellite cells decreases.
In an article in Science Daily, Professor Yusuke Ono, the leader of the study, says it’s possible that DMDFs play an even greater role in the body:
“In this study, we proposed a new muscle injury-regeneration model. However, the detailed molecular mechanism of how DMDFs activate satellite cells remains an unclear issue for future research. In addition to satellite cell activation, DMDF moonlighting functions are expected to be diverse. Recent studies have shown that skeletal muscle secretes various factors that affect other organs and tissues, such as the brain and fat, into the bloodstream, so it may be possible that DMDFs are involved in the linkage between injured muscle and other organs via blood circulation. We believe that further elucidation of the functions of DMDFs could clarify the pathologies of some muscle diseases and help in the development of new drugs.”
At CIRM we are modest enough to know that we can’t do everything by ourselves. To succeed we need partners. And in UC Davis we have a terrific partner. The work they do in advancing stem cell research is exciting and really promising. But it’s not just the science that makes them so special. It’s also their compassion and commitment to caring for patients.
What follows is an excerpt from an article by Lisa Howard on the work they do at UC Davis. When you read it you’ll see why we are honored to be a part of this research.
Gene therapy research at UC Davis
UC Davis’ commitment to stem cell and gene therapy research dates back more than a decade.
In 2010, with major support from the California Institute for Regenerative Medicine (CIRM), UC Davis launched the UC Davis Institute for Regenerative Cures, which includes research facilities as well as a Good Manufacturing Practice (GMP) facility.
Led by Jan Nolta, a professor of cell biology and human anatomy and the director of the UC Davis Institute for Regenerative Cures, the new center leverages UC Davis’ network of expert researchers, facilities and equipment to establish a center of excellence aimed at developing lifelong cures for diseases.
Nolta began her career at the University of Southern California working with Donald B. Kohn on a cure for bubble baby disease, a condition in which babies are born without an immune system. The blood stem cell gene therapy has cured more than 50 babies to date.
Work at the UC Davis Gene Therapy Center targets disorders that potentially can be treated through gene replacement, editing or augmentation.
“The sectors that make up the core of our center stretch out across campus,” said Nolta. “We work with the MIND Institute a lot. We work with the bioengineering and genetics departments, and with the Cancer Center and the Center for Precision Medicine and Data Sciences.”
A recent UC Davis stem cell study shows a potential breakthrough for healing diabetic foot ulcers with a bioengineered scaffold made up of human mesenchymal stem cells (MSCs). Another recent study revealed that blocking an enzyme linked with inflammation enables stem cells to repair damaged heart tissue. A cell gene therapy study demonstrated restored enzyme activity in Tay-Sachs disease affected cells in humanized mouse models.
“Some promising and exciting research right now at the Gene Therapy Center comes from work with hematopoietic stem cells and with viral vector delivery,” said Nolta.
Hematopoietic stem cells give rise to other blood cells. A multi-institutional Phase I clinical trial using hematopoietic stem cells to treat HIV-lymphoma patients is currently underway at UC Davis.
“We are genetically engineering a patient’s own blood stem cells with genes that block HIV infection,” said Joseph Anderson, an associate professor in the UC Davis Department of Internal Medicine. The clinical trial is a collaboration with Mehrdad Abedi, the lead principal investigator.
“When the patients receive the modified stem cells, any new immune system cell, like T-cell or macrophage, that is derived from one of these stem cells, will contain the HIV-resistant genes and block further infection,” said Anderson.
He explained that an added benefit with the unique therapy is that it contains an additional gene that “tags” the stem cells. “We are able to purify the HIV-resistant cells prior to transplantation, thus enriching for a more protective cell population.
Kyle David Fink
Kyle David Fink, an assistant professor of neurology at UC Davis, is affiliated with the Stem Cell Program and Institute for Regenerative Cures. His lab is focused on leveraging institutional expertise to bring curative therapies to rare, genetically linked neurological disorders.
“We are developing novel therapeutics targeted to the underlying genetic condition for diseases such as CDKL5 deficiency disorder, Angelman, Jordan and Rett syndromes, and Juvenile Huntington’s disease,” said Fink.
The lab is developing therapies to target the underlying genetic condition using DNA-binding domains to modify gene expression in therapeutically relevant ways. They are also creating novel delivery platforms to allow these therapeutics to reach their intended target: the brain.
“The hope is that these highly innovative methods will speed up the progress of bringing therapies to these rare neurodegenerative disease communities,” said Fink.

Developing potential lifetime cures
Among Nolta’s concerns is how expensive gene therapy treatments can be.
“Some of the therapies cost half a million dollars and that’s simply not available to everyone. If you are someone with no insurance or someone on Medicare, which reimburses about 65 percent, it’s harder for you to get these life-saving therapies,” said Nolta.
To help address that for cancer patients at UC Davis, Nolta has set up a team known as the “CAR T Team.”
Chimeric antigen receptor (CAR) T-cell therapy is a type of immunotherapy in which a patient’s own immune cells are reprogrammed to attack a specific protein found in cancer cells.
“We can develop our own homegrown CAR T-cells,” said Nolta. “We can use our own good manufacturing facility to genetically engineer treatments specifically for our UC Davis patients.”
Although safely developing stem cell treatments can be painfully slow for patients and their families hoping for cures, Nolta sees progress every day. She envisions a time when gene therapy treatments are no longer considered experimental and doctors will simply be able to prescribe them to their patients.
“And the beauty of the therapy is that it can work for the lifetime of a patient,” said Nolta.
Over 650,000 Americans suffer from end-stage kidney disease – a life-threatening condition caused by the loss of kidney function. The best available treatment for these patients is a kidney transplant from a genetically matched living donor. However, patients who receive a transplant must take life-long immunosuppressive drugs to prevent their immune system from rejecting the transplanted organ. Over time, these drugs are toxic and can increase a patient’s risk of infection, heart disease, cancer and diabetes. Despite these drugs, many patients still lose transplanted organs due to rejection.
To tackle this problem Medeor is developing a stem cell-based therapy called MDR-101. This is being tested in a Phase 3 clinical trial and it’s hoped it will eliminate the need for immunosuppressive drugs in genetically matched kidney transplant patients.
The company takes blood-forming stem cells and immune cells from the organ donor and infuses them into the patient receiving the donor’s kidney. Introducing the donor’s immune cells into the patient creates a condition called “mixed chimerism” where immune cells from the patient and the donor are able to co-exist. In this way, the patient’s immune system is able to adapt to and tolerate the donor’s kidney, potentially eliminating the need for the immunosuppressive drugs that are normally necessary to prevent transplant rejection.
So how does getting RMAT designation help that? Well, the FDA created the RMAT program to help speed up the development and review of regenerative medicine therapies that can treat, modify, reverse, or cure a serious condition. If MDR-101shows it is both safe and effective RMAT could help it get faster approval for wider use.
In a news release Giovanni Ferrara, President and CEO of Medeor, welcomed the news.
“This important designation underscores the tremendous unmet medical need for alternatives to today’s immunosuppressive therapies for transplantation. We have the potential to help people live longer, healthier lives without the need for high dose and chronic immunosuppression and we thank the FDA for this designation that will assist us progressing as efficiently as possible toward a commercially available product.”
It’s been a long time coming. Eighteen months to be precise. Which is a peculiarly long time for an Annual Report. The world is certainly a very different place today than when we started, and yet our core mission hasn’t changed at all, except to spring into action to make our own contribution to fighting the coronavirus.
This latest CIRM Annual Reportcovers 2019 through June 30, 2020. Why? Well, as you probably know we are running out of money and could be funding our last new awards by the end of this year. So, we wanted to produce as complete a picture of our achievements as we could – keeping in mind that we might not be around to produce a report next year.
It’s a pretty jam-packed report. It covers everything from the 14 new clinical trials we have funded this year, including three specifically focused on COVID-19. It looks at the extraordinary researchers that we fund and the progress they have made, and the billions of additional dollars our funding has helped leverage for California. But at the heart of it, and at the heart of everything we do, are the patients. They’re the reason we are here. They are the reason we do what we do.
There are stories of people like Byron Jenkins who almost died from multiple myeloma but is now back leading a full, active life with his family thanks to a CIRM-funded therapy with Poseida. There is Jordan Janz, a young man who once depended on taking 56 pills a day to keep his rare disease, cystinosis, under control but is now hoping a stem cell therapy developed by Dr. Stephanie Cherqui and her team at UC San Diego will make that something of the past.
These individuals are remarkable on so many levels, not the least because they were willing to be among the first people ever to try these therapies. They are pioneers in every sense of the word.
There is a lot of information in the report, charting the work we have done over the last 18 months. But it’s also a celebration of everyone who made it possible, and our way of saying thank you to the people of California who gave us this incredible honor and opportunity to do this work.
Last week saw a flurry of really encouraging reports from projects that CIRM has supported. We blogged about two of them last Wednesday, but here’s another two programs showing promising results.
UC San Diego researcher Dr. Stephanie Cherqui is running a CIRM-funded clinical trial for cystinosis. This is a condition where patients lack the ability to clear an amino acid called cystine from their cells. As the cystine builds up it can lead to multi-organ failure affecting the kidneys, eyes, thyroid, muscle, and pancreas.
Dr. Cherqui uses the patient’s own blood stem cells, that have been genetically corrected in the lab to remove the defective gene that causes the problem. It’s hoped these new cells will help reduce the cystine buildup.
The data presented at the annual meeting of the American Society of Cell and Gene Therapy (ASCGT) focused on the first patient treated with this approach. Six months after being treated the patient is showing positive trends in kidney function. His glomerular filtration rate (a measure of how well the kidneys are working) has risen from 38 (considered a sign of moderate to severe loss of kidney function) to 52 (mild loss of kidney function). In addition, he has not had to take the medication he previously needed to control the disorder, nor has he experienced any serious side effects from the therapy.
Capricor Therapeutics also had some positive news about its therapy for people with Duchenne’s Muscular Dystrophy (DMD). This is a progressive genetic disorder that slowly destroys the muscles. It affects mostly boys. By their teens many are unable to walk, and most die of heart or lung failure in their 20’s.
Capricor is using a therapy called CAP-1002, using cells derived from heart stem cells, in the HOPE-2 clinical trial.
In a news release Capricor said 12-month data from the trial showed improvements in heart function, lung function and upper body strength. In contrast, a placebo control group that didn’t get the CAP-1002 treatment saw their condition deteriorate.
Craig McDonald, M.D., the lead investigator on the study, says these results are really encouraging. “I am incredibly pleased with the outcome of the HOPE-2 trial which demonstrated clinically relevant benefits of CAP-1002 which resulted in measurable improvements in upper limb, cardiac and respiratory function. This is the first clinical trial which shows benefit to patients in advanced stages of DMD for which treatment options are limited.”
To help with the coronavirus pandemic, many scientists are repurposing previously developed approaches or treatments to see if they can be used to treat patients with COVID-19. Capricor Therapeutics, lead by Dr. Linda Marbán, is using cardiosphere derived cells (CDCs), which are stem cells derived from heart tissue, to treat critically ill patients with COVID-19.
When a patient contracts the virus, their body produces cytokines, proteins that play an important role in the immune response. Unfortunately, having too many cytokines, known as a “cytokine storm”, leads to a severe immune reaction that can cause pneumonia, organ failure, and death. CDCs in previous studies have been shown to help regulate the immune response and cytokines, which could help patients with COVID-19.
Over the course of one month, six critically ill patients with COVID-19, five of whom were on mechanical ventilators, were treated with CDCs. In these compassionate care cases, five male patients and one female patient received treatment. Of the five patients on ventilator support, four patients no longer required ventilator support within just one to four days after treatment. Although these results are promising, it is important to remember that this treatment is in very early testing and will need to demonstrate significant improvement in larger patient groups.
Following a review of the results of this small study, the U.S. Food and Drug Administration (FDA) approved treatment of up to an 20 additional COVID-19 patients.
In a press release, Dr. Marbán discuses the results of the compassionate care study and treatment of additional COVID-19 patients.
“As the global medical community continues to come together in its battle against COVID-19, the results of our initial compassionate care cases are extremely promising and what we had anticipated. We look forward to continuing to treat additional patients under our recently approved expanded access program Investigational New Drug application.”
This past Wednesday was Stem Cell Awareness Day, a day that is meant to remind us all of the importance of stem cell research and the potential it has to treat a wide variety of diseases. On this day, we also released an independent Economic Impact Report that showed how $10.7 Billion (yes, you read that right) was generated as a direct result of the the legacy we have built as a state agency that funds groundbreaking research.
Aside from the monetary incentive, which is an added bonus, the research we fund has made encouraging progress in the scientific field and has demonstrated the positive impact it can have on various disease areas. This week, two clinical trials supported by CIRM funding have released very promising updates.
Duchenne Muscular Dystrophy
Capricor Therapeutics, Inc. has presented positive results for a clinical trial related to a treatment for duchenne muscular dystrophy (DMD), a genetic disorder. DMD leads to progressive muscle degeneration and weakness due to its effect on a protein called dystrophin, which helps keep muscle cells intact.
The treatment that Capricor is testing is called CAP-1002 and consists of a unique population of cells that contain cardiac progenitor cells, a type of stem cell, that help encourage the regeneration of cells. CIRM funded an earlier clinical trial for this treatment.
The early results of this current trial describe how teens and young men in the advanced stages of DMD saw improvements in skeletal, lung, and heart measurements after receiving multiple doses of the treatment.
In a news release, Dr. Linda Marban, Chief Executive Officer of Capricor, expresses optimism for this clinical trial by saying,
“We are very pleased that the interim analysis from this double-blind placebo-controlled study, has demonstrated meaningful improvements across three clinically relevant endpoints in older patients with limited remaining treatment options.”
In the same news release, Dr. Craig McDonald, the national principal investigator for the trial, echoes the same sentiment by stating,
“The results from this trial to date are very promising in that the cells appear to positively impact skeletal, pulmonary and cardiac assessments in older DMD patients who have few, if any, remaining treatment options. We are eager to meet with the FDA to discuss the next steps for this promising program.”
Mantle Cell Lymphoma
Additionally, Oncternal Therapeutics has decided, because of positive results, to open an expansion of its CIRM-funded clinical trial aimed at treating patients with mantle cell lymphoma (MCL). The treatment involves an antibody called cirmtuzumab, named after us, in combination with a drug called ibrutinib.
The preliminary results were from the first six patients with MCL that were treated in the trial. One patient with MCL, who had relapsed following an allogeneic stem cell transplant, experienced a confirmed complete response (CR) after three months of cirmtuzumab plus ibrutinib treatment. This complete response appears to be sustained and has been confirmed to be ongoing after completing 12 months of the combination treatment. A second confirmed complete response occurred in a patient who had progressive disease after failing several different chemotherapy regimens, bone marrow transplant and CAR-T therapy.
In a news release, Dr. Hun Lee, an investigator in the trial, states that,
“It is encouraging to see that the drug has been well tolerated as well as the early signal of efficacy of cirmtuzumab with ibrutinib in MCL, particularly the rapid and durable complete responses of the heavily pre-treated patients after three months of therapy, which is an unusually fast response in this patient population.”
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.
Proposition 71 is the state ballot initiative that created California’s Stem Cell Agency. This month, the Agency reached another milestone when the 71st clinical trial was initiated in the CIRM Alpha Stem Cell Clinics (ASCC) Network. The ASCC Network deploys specialized teams of doctors, nurses and laboratory technicians to conduct stem cell clinical trials at leading California Medical Centers.
These teams work with academic and industry partners to support patient-centered for over 40 distinct diseases including:
Amyotrophic Lateral Sclerosis (ALS)
Brain Injury & Stroke
Cancer at Multiple Sites
Diabetes Type 1
Eye Disease / Blindness Heart Failure
HIV / AIDS
Severe Combined Immunodeficiency (SCID)
Sickle Cell Anemia
Spinal Cord Injury
These clinical trials have treated over 400 patients and counting. The Alpha Stem Cell Clinics are part of CIRM’s Strategic Infrastructure. The Strategic Infrastructure program which was developed to support the growth of stem cell / regenerative medicine in California. A comprehensive update of CIRM’s Infrastructure Program was provided to our Board, the ICOC.
CIRM’s infrastructure catalyzes stem cell / regenerative medicine by providing resources to all qualified researchers and organizations requiring specialized expertise. For example, the Alpha Clinics Network is supporting clinical trials from around the world.
Many of these trials are sponsored by commercial companies that have no CIRM funding. To date, the ASCC Network has over $27 million in contracts with outside sponsors. These contracts serve to leverage CIRMs investment and provide the Network’s medical centers with a diverse portfolio of clinical trials to address patients’’ unmet medical needs.
Alpha Clinics – Key Performance Metrics
70+ Clinical Trials
400+ Patients Treated
40+ Disease Indications
Over $27 million in contracts with commercial sponsors
The CIRM Alpha Stem Cell Clinics and broader Infrastructure Programs are supporting stem cell research and regenerative medicine at every level, from laboratory research to product manufacturing to delivery to patients. This infrastructure has emerged to make California the world leader in regenerative medicine. It all started because California’s residents supported a ballot measure and today we have 71 clinical trials for 71.
In 2017 Texas passed a sweeping new law, HB 810, which allowed medical clinics to provide “investigational stem cell treatments to patients with certain severe chronic diseases or terminal illnesses.” Those in favor of the law argued that patients battling life-threatening or life-changing diseases should have the right to try stem cell therapies that were involved in a clinical trial.
Now a new study, published in the journal Stem Cells and Development, looks at the impact of the law. The report says that despite some recent amendments t there are still some concerns about the law including:
It allows treatment only if the patient has a “severe, chronic” illness but doesn’t define what that means
It doesn’t have clearly defined procedures on tracking and reporting procedures so it’s hard to know how many patients might be treated and what the outcomes are
There is no Food and Drug Administration (FDA) oversight of the patients being treated
Because the treatments are unproven there are fears this will “open up the state to unsavory and predatory practices by individuals preying on vulnerable patients”
The researchers conclude:
“While HB 810 opens up access to patients, it also increases significant risks for their safety and financial cost for something that might have no positive impact on their disease. Truly understanding the impact of stem cell based interventions (SCBI) requires scientific rigor, and accurate outcome data reporting must be pursued to ensure the safety and efficacy behind such procedures. This information must be readily available so that patients can make informed decisions before electing to pursue such treatments. The creation of the SCBI registry could allow for some level of scientific rigor, provide a centralized data source, and offer the potential for better informed patient choices, and might be the best option for the state to help protect patients.”
Another CIRM-funded company gets RMAT designation
When Congress approved the 21st Century Cures Act a few years ago one of the new programs it created was the Regenerative Medicine Advanced Therapy (RMAT) designation. This was given to therapies that are designed to treat a serious or life-threatening condition, where early clinical stage trials show the approach is safe and appears to be effective.
Getting an RMAT designation is a big deal. It means the company or researchers are able to apply for an expedited review by the FDA and could get approval for wider use.
This week Poseida Therapeutics was granted RMAT designation by the Food and drug Administration (FDA) for P-BCMA-101, its CAR-T therapy for relapsed/refractory multiple myeloma. This is currently in a Phase 1 clinical trial that CIRM is funding
In this trial Poseida’s technology takes an immunotherapy approach that uses the patient’s own engineered immune system T cells to seek and destroy cancerous myeloma cells.
In a news release Eric Ostertag, Poseida’s CEO, welcomed the news:
“Initial Phase 1 data presented at the CAR-TCR Summit earlier this year included encouraging response rates and safety data, including meaningful responses in a heavily pretreated population. We expect to have an additional data update by the end of the year and look forward to working closely with the FDA to expedite development of P-BCMA-101.”
This means that five CIRM-funded companies have now been granted RMAT designations:
