Yesterday the governing Board of the California Institute for Regenerative Medicine (CIRM) awarded $9.28 million to Dr. Saul Priceman at City of Hope to conduct a clinical trial for the treatment of breast cancer related brain metastases, which are tumors in the brain that have spread from the original site of the breast cancer.
This award brings the total number of CIRM-funded clinical trials to 56.
Breast cancer is the second-most common cancer in women, both in the United States (US) and worldwide. It is estimated that over 260,000 women in the US will be diagnosed with breast cancer in 2019 and 1 out of 8 women in the US will get breast cancer at some point during her lifetime. Some types of breast cancer have a high likelihood of metastasizing to the brain. When that happens, there are few treatment options, leading to a poor prognosis and poor quality of life.
Dr. Priceman’s clinical trial is testing a therapy to treat brain metastases that came from breast cancers expressing high levels of a protein called HER2. The therapy consists of a genetically-modified version of the patient’s own T cells, which are an immune system cell that can destroy foreign or abnormal cells. The T cells are modified with a protein called a chimeric antigen receptor (CAR) that recognizes the tumor protein HER2. These modified T cells (CAR-T cells) are then infused into the patient’s brain where they are expected to detect and destroy the HER2-expressing tumors in the brain.
CIRM has also funded the earlier work related to this study, which was critical in preparing the therapy for Food and Drug Administration (FDA) approval for permission to start a clinical trial in people.
“When a patient is told that their cancer has metastasized to other areas of the body, it can be devastating news,” says Maria T. Millan, M.D., the President and CEO of CIRM. “There are few options for patients with breast cancer brain metastases. Standard of care treatments, which include brain irradiation and chemotherapy, have associated neurotoxicity and do little to improve survival, which is typically no more than a few months. CAR-T cell therapy is an exciting and promising approach that now offers us a more targeted approach to address this condition.”
The CIRM Board also approved investing $19.7 million in four awards in the Translational Research program. The goal of this program is to help promising projects complete the testing needed to begin talking to the US Food and Drug Administration (FDA) about holding a clinical trial.
Dr. Mark Tuszynski at the University of California San Diego (UCSD) was awarded $6.23 million to develop a therapy for spinal cord injury (SCI). Dr. Tuszynski will use human embryonic stem cells (hESCs) to create neural stem cells (NSCs) which will then be grafted at the injury site. In preclinical studies, the NSCs have been shown to help create a kind of relay at the injury site, restoring communication between the brain and spinal cord and re-establishing muscle control and movement.
Dr. Mark Humayun at the University of Southern California (USC) was awarded $3.73 million to develop a novel therapeutic product capable of slowing the progression of age-related macular degeneration (AMD), the leading cause of vision loss in the US.
The approach that Dr. Humayun is developing will use a biologic product produced by human embryonic stem cells (hESCs). This material will be injected into the eye of patients with early development of dry AMD, supporting the survival of photoreceptors in the affected retina, the kind of cells damaged by the disease.
The TRAN1 awards went to:
Stay tuned for our next blog which will dive into each of these awards in much more detail.
Fragile X syndrome (FXS) is a genetic disorder that is the most common form of inherited intellectual disability in children, and has also been linked to a form of autism. Uncovering the cause of FXS could help lead to a deeper understanding of autism, what causes it and ultimately, it’s hoped, to treating or even preventing it.
Researchers at Children’s Hospital in Chicago looked at FXS at the stem cell level and found how a genetic defect has an impact on the development of neurons (nerve cells in the brain) and how that in turn has an impact on the developing brain in the fetus.
In a news release on Eurekalert, Dr. Yongchao Ma, the senior author of the study, says this identified a problem at a critical point in the development of the brain:
“During embryonic brain development,
the right neurons have to be produced at the right time and in the right
numbers. We focused on what happens in the stem cells that leads to slower
production of neurons that are responsible for brain functions including learning
and memory. Our discoveries shed light on the earliest stages of disease
development and offer novel targets for potential treatments.”
The team looked at neural stem cells and found that a lack
of one protein, called FMRP, created a kind of cascade that impacted the
ability of the cells to turn into neurons. Fewer neurons meant impaired brain
The findings, published in the journal Cell Reports, help explain how
genetic information flows in cells in developing babies and, according to Dr.
Ma, could lead to new ideas on how to treat problems.
“Currently we are exploring how to
stimulate FMRP protein activity in the stem cell, in order to correct the
timing of neuron production and ensure that the correct amount and types of
neurons are available to the developing brain. There may be potential for gene
therapy for fragile X syndrome.”
Heart disease continues to be the number one cause of death in the United States. An estimated 375,000 people have a genetic form of heart disease known as familial dilated cardiomyopathy. This occurs when the heart muscle becomes weakened in one chamber in the heart, causing the open area of the chamber to become enlarged or dilated. As a result of this, the heart can no longer beat regularly, causing shortness of breath, chest pain and, in severe cases, sudden and deadly cardiac arrest.
A CIRM funded study by a team of researchers at Stanford University looked further into this form of genetic heart disease by taking a patient’s skin cells and converting them into stem cells known as induced pluripotent stem cells (iPSCs), which can become any type of cell in the body. These iPSCs were then converted into heart muscle cells that pulse just as they do in the body. These newly made heart muscle cells beat irregularly, similar to what is observed in the genetic heart condition.
Upon further analysis, the researchers linked a receptor called PGDF to cause various genes to be more highly activated in the mutated heart cells compared to normal ones. Two drugs, crenolanib and sunitinib, interfere with the PGDF receptor. After treating the abnormal heart cells, they began beating more regularly, and their gene-activation patterns more closely matched those of cells from healthy donors.
These two drugs are already FDA-approved for treating various cancers, but previous work shows that the drugs may damage the heart at high doses. The next step would be determining the right dose of the drug. The current study is part of a broader effort by the researchers to use these patient-derived cells-in-a-dish to screen for and discover new drugs.
Dr. Joseph Wu, co-senior author of this study, and his team have generated heart muscle cells from over 1,000 patients, including those of Dr. Wu, his son, and his daughter. In addition to using skin cells, the same technique to create heart cells from patients can also be done with 10 milliliters of blood — roughly two teaspoons.
“With 10 milliliters of blood, we can make clinically usable amounts of your beating heart cells in a dish…Our postdocs have taken my blood and differentiated my pluripotent stem cells into my brain cells, heart cells and liver cells. I’m asking them to test some of the medications that I might need to take in the future.”
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.
Medical treatments for a variety of diseases have advanced dramatically in recent decades, but sometimes they come with a cost; namely damage to surrounding tissues and organs. That’s where stem cell research and regenerative medicine come in. Those fields seek to develop new ways of repairing the damage. But how do you see if those repairs are working? Researchers at Purdue say they have found a way to do just that.
The researchers have developed a 3D technology that allows
them to track, map and monitor what happens with cells and tissues that are
being used to repair damage caused by disease or the treatment for the disease.
By observing the cells and tissues they can see if they are staying where they
are needed and if they are working.
The technology, published in the journalACS Nano, uses tiny sensors placed on a flexible scaffold to monitor the new materials in the body. Ingeniously the scaffold is buoyant, so it can float and survive in the wet conditions found in many parts of the body.
In a news
release, Chi Hwan Lee, the leader of the research team, says the device could
help millions of people:
engineering already provides new hope for hard-to-treat disorders, and our
technology brings even more possibilities. This device offers an expanded set
of potential options to monitor cell and tissue function after surgical transplants
in diseased or damaged bodies. Our technology offers diverse options for
sensing and works in moist internal body environments that are typically
unfavorable for electronic instruments.”
Purdue created this video showing the device and explaining how it works.
A sense of balance is important for a wide range of activities, from simple ones such as walking, running, and driving, to more intricate ones such as dancing, rock climbing, and tight-rope walking. A lack of physical balance in the body can lead to an inbalance in trying to live a normal everyday life.
One primary cause of balance disorders is a problem with hair cells located inside the inner ear, which play a role in maintaining balance, spatial orientation, and regulating eye movement. Damage to these cells can occur as a result from infections, genetic disorders, or aging. Unfortunately, in humans, hair cells in the inner ear regenerate on their own very minimally. In the United States alone, 69 million people experience balance disorders. Symptoms of this disorder include a “spinning” feeling, lack of balance, nausea, and difficulty tracking objects using the eyes.
However, a CIRM funded study has showed promising results for helping treat this disorder. Researchers at Stanford University have discovered a way to regenerate hair cells in the inner ear of mice, giving them a better sense of balance. To do this, the researchers impaired the hair cells in the inner ear of mice and measured how well they regenerated on their own to obtain a baseline measurement. They found that about a third of the cells regenerated on their own.
Next, the researchers manipulated Atoh1, a transcription factor that regulates hair cell formation in mice. By overexpressing Atoh1, the researchers found that as much as 70% of hair cells regenerated in the mice. Additionally, 70% of these mice also recovered their sense of balance. This simple proof of concept could potentially be applied in humans to treat similar disorders related to the loss of hair cells in the inner ear.
In a press release, Dr. Alan Cheng, senior author of this study, is quoted as saying,
“This is very exciting. It’s an important first step to find treatment for vestibular disorders. We couldn’t get sufficient regeneration to recover function before.”
There’s a wonderful moment at the end of the movie The Candidate (starring Robert Redford, 87% approval on Rotten Tomatoes!) about a modern political campaign for a US Senate seat. Redford (spoiler alert) plays a come-from-behind candidate and at the end when he wins he turns to his campaign manager and says “Now what?”.
I think that’s how a lot of people associated with Proposition
71 felt when it was approved by California voters in 2004, creating CIRM. Now
what? During the campaign you are so focused on crossing the finish line that when
the campaign is over you have to pause because you just realized it wasn’t the
finishing line, it was actually the starting line.
For us “now what” involved hiring a staff, creating
oversight groups of scientists and ethics experts, developing strategies and
then mechanisms for funding, and then mechanisms for tracking that funding to
make sure it was being used properly. It was creating something from scratch
and trying to do something that no state agency had done before.
Fifteen years later we are coming to the end of the funding
provided by Prop 71 and that question keeps popping up again, “Now what?” And
that’s what we are going to be talking about in our next Facebook Live.
We have three great experts on our panel. They are scientists
and researchers and leaders in biotech, but also members of our CIRM Board. We
rely on their experience and expertise in making key decisions and you can rely
on them to pull back the curtain and talk about the things that matter most to
them in helping advance our mission, and in helping secure our legacy.

Battling cancer is always a balancing act. The methods we use – surgery, chemotherapy and radiation – can help remove the tumors but they often come at a price to the patient. In cases where the cancer has spread to the bone the treatments have a limited impact on the disease, but their toxicity can cause devastating problems for the patient. Now, in a CIRM-supported study, researchers at UC Irvine (UCI) have developed a method they say may be able to change that.
Bone metastasis –
where cancer starts in one part of the body, say the breast, but spreads to the
bones – is one of the most common complications of cancer. It can often result
in severe pain, increased risk of fractures and compression
of the spine. Tackling them is difficult because some cancer cells can
alter the environment around bone, accelerating the destruction of healthy bone
cells, and that in turn creates growth factors that stimulate the growth of the
cancer. It is a vicious cycle where one problem fuels the other.
Now researchers at
UCI have developed a method where they combine engineered mesenchymal stem cells (taken from the bone marrow) with
targeting agents. These act like a drug delivery device, offloading
different agents that simultaneously attack the cancer but protect the bone.
In a news release Weian Zhao, lead author of the study, said:
“What’s powerful about this
strategy is that we deliver a combination of both anti-tumor and anti-bone
resorption agents so we can effectively block the vicious circle between
cancers and their bone niche. This is a safe and almost nontoxic treatment
compared to chemotherapy, which often leaves patients with lifelong issues.”
published in the journal EBioMedicine,
has already been shown to be effective in mice. Next, they hope to be able to
do the safety tests to enable them to apply to the Food and Drug Administration
for permission to test it in people.
The team say if this
approach proves effective it might also be used to help treat other bone-related
diseases such as osteoporosis and multiple myeloma.
In the United States alone, there are approximately 1.1 million people living with Human immunodeficiency virus (HIV), a virus that weakens the immune system by destroying important cells that fight off disease and infection. This number is much larger on a global scale, with 36.9 million people living with HIV as of 2017. If left untreated, the immune system becomes so weakened that the condition worsens into acquired immunodeficiency syndrome (AIDS), which is usually fatal.
Current treatment for HIV focuses on the use of antiretroviral therapy (ART). This treatment is able to suppress replication of the virus, but it does not eliminate it from the body entirely. In order to be sustainable, ART must be taken throughout the course of a lifetime, otherwise HIV rebounds and the replication of the virus renews, fueling the development of AIDS.
The ability of HIV to rebound is related to the fact that it is able to integrate its DNA into various cells inside the body and beyond the reach of ART. Here they are able to remain dormant and ready to replicate as soon as ART is not interfering. It is because of this that ART is not sufficient on its own to cure HIV, but a group of scientists have uncovered a promising breakthrough to change that.
In a major collaboration, researchers at the Lewis Katz School of Medicine at Temple University and the University of Nebraska Medical Center (UNMC) have for the first time eliminated HIV from the DNA of living mice. This study marks a critical step toward the development of a possible cure for human HIV infection.
The team of researchers was able to do this with the help of a new technology called long-acting slow-effective release (LASER) ART. LASER ART is able to target HIV sanctuaries and maintain replication at low levels for extended periods of time. Immediately after administering LASER ART, the team used a gene editing technology known as CRISPR to remove the final remnants of HIV DNA hidden inside cells.
In a press release, Dr. Kamel Khalili, senior investigator for this study, was quoted as saying,
“Our study shows that treatment to suppress HIV replication and gene editing therapy, when given sequentially, can eliminate HIV from cells and organs of infected animals…We now have a clear path to move ahead to trials in non-human primates and possibly clinical trials in human patients within the year.”
The full results of this study were published in Nature Communications.
To learn more about how CRISPR technology works, you can read more about it on a previous blog post.
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.
