Tay-Sachs disease is a rare genetic disorder where a deficiency in the Hex A gene results in excessive accumulation of certain fats in the brain and nerve cells and causes progressive dysfunction.
There are several forms of Tay-Sachs disease, including an infant, juvenile, and adult forms. Over a hundred mutations in the disease-causing Hex A gene have been identified that result in enzyme disfunction. There are currently no effective therapies or cures for Tay-Sachs.
The UC Davis team will genetically modify the patient’s own blood stem cells to restore the Hex A enzyme that is missing in the disease.
The goal is to complete safety studies and to apply to the US Food and Drug Administration for an Investigational New Drug (IND), the authorization needed to begin a clinical trial in people.
“The successful development of this therapy will not only help patients with Tay-Sachs but will demonstrate the use case of this therapeutic approach for other monogenic neurodegenerative diseases,” the UC Davis team said.
This work is a continuation of aCIRM grantthat the team received.
El bebé, Tobi recibió un tratamiento de células madre, financiado por el CIRM, mientras aún estaba en el útero.To read this blog in English, click here.
Michelle y Jeff se llenaron de felicidad cuando se enteraron de que iban a tener un bebé.
Luego, un examen de ultrasonido a las 20 semanas del embarazo reveló que el feto tenía espina bífida, una malformación congénita que ocurre cuando la columna vertebral y la médula espinal no se forman de manera adecuada. La espina bífida puede causar parálisis y otras complicaciones serias.
Se derivó a la pareja a un ensayo clínico en la Universidad de California, Davis, que lleva a cabo la Dra. Diana Farmer, cirujana fetal y neonatal reconocida a nivel internacional, y su colega, el Dr. Aijun Wang.
En este ensayo clínico, que se basó en una previa investigación financiada por el CIRM, se repara el defecto espinal aplicando células madre de una placenta donada, las cuales se insertan en una estructura sintética y se aplican al defecto de la médula espinal mientras el bebé se encuentra todavía en el útero.
El hijo de Michelle y Jeff, Tobi, fue el segundo paciente que recibió este tratamiento. Michelle dijo que la cirugía fue difícil, pero el nacimiento de su bebé valió la pena.
“Cuando lo abrazamos por primera vez dijimos, ‘No puedo creer que hayamos hecho esto. Lo logramos. Lo hicimos sin saber si funcionaría’.”
A los tres meses, el progreso de Tobi parece promisorio. Jeff y Michelle saben que pueden surgir problemas más adelante, pero por ahora se sienten agradecidos de haber formado parte de este ensayo.
Every year California performs around 100 kidney transplants in children but, on average, around 50 of these patients will have their body reject the transplant. These children then have to undergo regular dialysis while waiting for a new organ. Even the successful transplants require a lifetime of immunosuppression medications. These medications can prevent rejection but they also increase the risk of infection, gastrointestinal disease, pancreatitis and cancer.
Dr. Alice Bertaina and her team at Stanford University were awarded $11,998,188 to test an approach that uses combined blood stem cell (HSC) and kidney transplantation with the goal to improve outcomes with kidney transplantation in children. This approach seeks to improve on the blood stem cell preparation through an immune-based purification process.
In this approach, the donor HSC are transplanted into the patient in order to prepare for the acceptance of the donor kidney once transplanted. Donor HSC give rise to cells and conditions that re-train the immune system to accept the kidney. This creates a “tolerance” to the transplanted kidney providing the opportunity to avoid long-term need for medications that suppress the immune system.
Pre-clinical data support the idea that this approach could enable the patient to stop taking any immunosuppression medications within 90 days of the surgery.
Dr. Maria T. Millan, President and CEO of CIRM, a former pediatric transplant surgeon and tolerance researcher states that “developing a way to ensure long-term success of organ transplantation by averting immune rejection while avoiding the side-effects of life-long immunosuppression medications would greatly benefit these children.”
The CIRM Board also awarded $7,141,843 to Dr. Ivan Kingand Tachyon Therapeutics, Inc to test a drug showing promise in blocking the proliferation of cancer stem cells in solid tumors such as colorectal and gastrointestinal cancer.
Patients with late-stage colorectal cancer are typically given chemotherapy to help stop or slow down the progression of the disease. However, even with this intervention survival rates are low, usually not more than two years.
Tachyon’s medication, calledTACH101, is intended to target colorectal cancer (CRC) stem cells as well as the bulk tumor by blocking an enzyme called KDM4, which cancer stem cells need to grow and proliferate.
In the first phase of this trial Dr. King and his team will recruit patients with advanced or metastatic solid tumors to assess the safety of TACH101, and determine what is the safest maximum dose. In the second phase of the trial, patients with gastrointestinal tumors and colorectal cancer will be treated using the dose determined in the first phase, to determine how well the tumors respond to treatment.
The CIRM Board also awarded $5,999,919 to Dr. Natalia Gomez-Ospina and her team at Stanford University for a late-stage preclinical program targeting Severe Mucopolysaccharidosis type 1, also known as Hurler syndrome. This is an inherited condition caused by a faulty gene. Children with Hurler syndrome lack an enzyme that the body needs to digest sugar. As a result, undigested sugar molecules build up in the body, causing progressive damage to the brain, heart, and other organs. There is no effective treatment and life expectancy for many of these children is only around ten years.
Dr. Gomez-Ospina will use the patient’s own blood stem cells that have been genetically edited to restore the missing enzyme. The goal of this preclinical program is to show the team can manufacture the needed cells, to complete safety studies and to apply to the US Food and Drug Administration for an Investigational New Drug (IND), the authorization needed to begin a clinical trial in people.
Finally the Board awarded $20,401,260 to five programs as part of its Translational program. The goal of the Translational program is to support promising stem cell-based or gene projects that accelerate completion of translational stage activities necessary for advancement to clinical study or broad end use. Those can include therapeutic candidates, diagnostic methods or devices and novel tools that address critical bottlenecks in research.

This brings the total number of CIRM funded clinical trials to 83.
$11,999,984 was awarded to Dr. Jana Portnow at the Beckman Research Institute of City of Hope. They are using Neural stem cells (NSCs) as a form of delivery vehicle to carry a cancer-killing virus that specifically targets brain tumor cells.
Glioblastoma is the most common malignant primary brain tumor in adults and each year about 12,000 Americans are diagnosed. The 5-year survival rate is only about 10%.
The current standard of care involves surgically removing the tumor followed by radiation, chemotherapy, and alternating electric field therapy. Despite these treatments, survival remains low.
The award to Dr. Portnow will fund a clinical trial to assess the safety and effectiveness of this stem cell-based treatment for Glioblastoma.
The Board also awarded $3,111,467 to Dr. Boris Minev of Calidi Biotherapeutics. This award is in the form of a CLIN1 grant, with the goal of completing the testing needed to apply to the Food and Drug Administration (FDA) for permission to start a clinical trial in people.
This project uses donor fat-derived mesenchymal stem cells that have been loaded with oncolytic virus to target metastatic melanoma, triple negative breast cancer, and advanced head & neck squamous cell carcinoma.
“There are few options for patients with advanced solid tumor cancers such as glioblastoma, melanoma, breast cancer, and head & neck cancer,” says Maria T. Millan, M.D., President and CEO of CIRM. “Surgical resection, chemotherapy and radiation are largely ineffective in advanced cases and survival typically is measured in months. These new awards will support novel approaches to address the unmet medical needs of patients with these devastating cancers.”
The CIRM Board also voted to approve awarding $71,949,539 to expand the CIRM Alpha Clinics Network. The current network consists of six sites and the Board approved continued funding for those and added an additional three sites. The funding is to last five years.
The goal of the Alpha Clinics award is to expand existing capacities for delivering stem cell, gene therapies and other advanced treatment to patients. They also serve as a competency hub for regenerative medicine training, clinical research, and the delivery of approved treatments.
Each applicant was required to submit a plan for Diversity, Equity and Inclusion to support and facilitate outreach and study participation by underserved and disproportionately affected populations in the clinical trials they serve.

The Board also unanimously, and enthusiastically, approved the election of Maria Gonzalez Bonneville to be the next Vice Chair of the Board. Ms. Bonneville, the current Vice President of Public Outreach and Board Governance at CIRM, was nominated by all four constitutional officers: the Governor, the Lieutenant Governor, the Treasurer and the Controller.
In supporting the nomination, Board member Ysabel Duron said: “I don’t think we could do better than taking on Maria Gonzalez Bonneville as the Vice Chair. She is well educated as far as CIRM goes. She has a great track record; she is empathetic and caring and will be a good steward for the taxpayers to ensure the work we do serves them well.”
In her letter to the Board applying for the position, Ms. Bonneville said: “CIRM is a unique agency with a large board and a long history. With my institutional knowledge and my understanding of CIRM’s internal workings and processes, I can serve as a resource for the new Chair. I have worked hand-in-hand with both the Chair and Vice Chair in setting agendas, prioritizing work, driving policy, and advising accordingly. I have worked hard to build trusted relationships with all of you so that I could learn and understand what areas were of the most interest and where I could help shed light on those particular programs or initiatives. I have also worked closely with Maria Millan for the last decade, and greatly enjoy our working relationship. In short, I believe I provide a level of continuity and expertise that benefits the board and helps in times of transition.”
In accepting the position Ms. Bonneville said: “I am truly honored to be elected as the Vice Chair for the CIRM Board. I have been a part of CIRM for 11 years and am deeply committed to the mission and this new role gives me an opportunity to help support and advance that work at an exciting time in the Agency’s life. There are many challenges ahead of us but knowing the Board and the CIRM team I feel confident we will be able to meet them, and I look forward to helping us reach our goals.”
Ms. Bonneville will officially take office in January 2023.
The vote for the new Chair of CIRM will take place at the Board meeting on December 15th.
I’ve always been impressed by the willingness of individuals to step forward and volunteer for a clinical trial. Even more so when they are the first person ever to test a first-in-human therapy. They really are pioneers in helping advance a whole new approach to treating disease.
That’s certainly the case for the first individual treated in a CIRM-funded clinical trial to develop a functional cure for HIV/AIDS. Caring Cross announced recently that they have dosed the first patient in the trial testing their anti-HIV duoCAR-T cell therapy.
The trial is being led by UC San Francisco’s Dr. Steven Deeks and UC Davis’ Dr. Mehrdad Abedi. Their approach involves taking a patient’s own blood and extracting T cells, a type of immune cell. The T cells are then genetically modified to express two different chimeric antigen receptors (CAR), which enable the newly created duoCAR-T cells to recognize and destroy HIV infected cells. The modified T cells are then reintroduced back into the patient.
The goal of this one-time therapy is to act as a long-term control of HIV with patients no longer needing to take anti-HIV medications. If it is successful it would be, in effect, a form of functional HIV cure.
This first phase involves giving different patients different levels of the duoCAR-T therapy to determine the best dose, and to make sure it is safe and doesn’t cause any negative side effects.
This is obviously just the first step in a long process, but it’s an important first step and certainly one worth marking. As Dr. Deeks said in the news release, “We have reached an important milestone with the dosing of the first participant in the Phase 1/2a clinical trial evaluating a potentially groundbreaking anti-HIV duoCAR-T cell therapy. Our primary goal for this clinical trial is to establish the safety of this promising therapeutic approach.”
Dr. Abedi, echoed that saying. “The first participant was dosed with anti-HIV duoCAR-T cells at the UC Davis medical center in mid-August. There were no adverse events observed that were related to the product and the participant is doing fine.”
This approach carries a lot of significance not just for people with HIV in the US, but also globally. If successful it could help address the needs of people who are not able to access antiretroviral therapies or for whom those medications are no longer effective.
Today there are an estimated 38 million people living with HIV around the world. Every year some 650,000 people die from the disease.

The California Institute for Regenerative Medicine (CIRM) recently shared some encouraging news on The Stem Cellar about a CIRM-funded stem cell clinical trial for spina bifida at UC Davis Health.
Spina bifida is a birth defect that occurs when the spine and spinal cord don’t form properly and can result in life-long walking and mobility problems for the child, even paralysis.
Now, UC Davis has released more details about the clinical trial and the babies born after receiving the world’s first spina bifida treatment combining surgery with stem cells. The story was featured in BBC News and The Sacramento Bee.
The first phase of the trial is funded by a $9 million grant from the California Institute for Regenerative Medicine.
The one-of-a-kind treatment, delivered while a fetus is still developing in the mother’s womb, could improve outcomes for children with this birth defect.
A Decade’s Work
“I’ve been working toward this day for almost 25 years now,” said Dr. Diana Farmer, the world’s first woman fetal surgeon, professor and chair of surgery at UC Davis Health and principal investigator on the study.
In previous clinical trial, Farmer had helped to prove that fetal surgery reduced neurological deficits from spina bifida. Many children in that study showed improvement but still required wheelchairs or leg braces.

Farmer recruited bioengineer Dr. Aijun Wang to help take that work to the next level. Together, they researched and tested ways to use stem cells and bioengineering to advance the effectiveness and outcomes of the surgery.
Farmer, Wang and their research team have been working on their novel approach using stem cells in fetal surgery for more than 10 years. Over that time, animal modeling has shown it is capable of preventing the paralysis associated with spina bifida.
Preliminary work by Farmer and Wang proved that prenatal surgery combined with human placenta-derived mesenchymal stromal cells, held in place with a biomaterial scaffold to form a “patch,” helped lambs with spina bifida walk without noticeable disability. When the team refined their surgery and stem cells technique for canines, the treatment also improved the mobility of dogs with naturally occurring spina bifida.
The CuRe Trial
When Emily and her husband Harry learned that they would be first-time parents, they never expected any pregnancy complications. But the day that Emily learned that her developing child had spina bifida was also the day she first heard about the CuRe trial, as the clinical trial is known.
Participating in the trial would mean that she would need to temporarily move to Sacramento for the fetal surgery and then for weekly follow-up visits during her pregnancy.
After screenings, MRI scans and interviews, Emily received the news that she was accepted into the trial. Her fetal surgery was scheduled for July 12, 2021, at 25 weeks and five days gestation.
Farmer and Wang’s team manufactured clinical grade stem cells—mesenchymal stem cells—from placental tissue in the UC Davis Health’s CIRM-funded Institute for Regenerative Cures. The lab is a Good Manufacturing Practice (GMP) Laboratory for safe use in humans. It is here that they made the stem cell patch for Emily’s fetal surgery.
The Procedure
During Emily’s historic procedure, a small opening was made in her uterus and they floated the fetus up to that incision point so they could expose its spine and the spina bifida defect.
Then, the stem cell patch was placed directly over the exposed spinal cord of the fetus. The fetal surgeons then closed the incision to allow the tissue to regenerate. The team declared the first-of-its-kind surgery a success.
On Sept. 20, 2021, at 35 weeks and five days gestation, Robbie was born at 5 pounds, 10 ounces, 19 inches long via C-section.
For Farmer, this day is what she had long hoped for, and it came with surprises. If Robbie had remained untreated, she was expected to be born with leg paralysis.

“It was very clear the minute she was born that she was kicking her legs and I remember very clearly saying, ‘Oh my God, I think she’s wiggling her toes!’” said Farmer. “It was amazing. We kept saying, ‘Am I seeing that? Is that real?’”
Both mom and baby are at home and in good health. Robbie just celebrated her first birthday.

The CuRe team is cautious about drawing conclusions and says a lot is still to be learned during this safety phase of the trial. The team will continue to monitor Robbie and the other babies in the trial until they are 6 years old, with a key checkup happening at 30 months to see if they are walking and potty training.
“This experience has been larger than life and has exceeded every expectation. I hope this trial will enhance the quality of life for so many patients to come,” Emily said. “We are honored to be part of history in the making.”

When I was in high school I spent my summers working in a shoe shop and playing soccer with my mates. It never occurred to me that I could do something really worthwhile with that time. So, when I meet the high school students who took part in the California Institute for Regenerative Medicine’s SPARK program I realized I had wasted a lot of time.
For those not familiar with SPARK, it stands for Summer Program to Accelerate Regenerative Medicine Knowledge. It’s a summer program offering high school students a chance to work in a world-class stem cell and gene therapy research facility. The quality of the work they do is truly remarkable. By the end of the summer they are doing projects that many full-time researchers would be proud of.
As part of that program the students also must write blogs and post photos and videos to Instagram to chart their progress. The quality of that work is equally impressive. Last week we posted items about the two best blogs from the students. But there were so many other fine entries that we thought it would be worthwhile to highlight elements of those.
For instance, Ricardo Rodriguez at Charles R. Drew University had some interesting observations on life, even when it’s not always working out the way you planned:

“Cancer is not life going wrong so much as it is life changing. If mutation is random, then so is life. That beautiful randomness that drives evolution and extinction, change and stagnation, life and death, and for you to think that that part of your body could be simple in any way, whether it be simply evil, simply inconvenient, simply structured, is simply hilarious. There is beauty in your body’s complexity, adaptability, and resilience, and these attributes are not barred from any part of your life.”
Mindy Rodriguez at Beckman City of Hope says she learned valuable lessons from working with mice, creatures she previously considered scary, dirty and vicious, but later came to like:
“The CIRM SPARK program reinforced the value of facing my fears by exploring the unknown and most importantly taught me to be comfortable with the uncomfortable. In both cases, I found that it is our response to fear that shapes who we are. We can either run away from the thing that scares us or take each moment as a learning opportunity, embracing change over comfort.”
Manvi Ketireddy at work at UC Davis
Manvi Ketireddy at UC Davis had a similar experience, learning to accept things not working out.
“A researcher must be persistent and have the ability to endure lots of failures. I think that is what I love about research: the slight possibility of discovery and answers amid constant defeat is one of the greatest challenges to exist. And boy, do I love challenges.”
Ameera Ali in the lab (fish not included)
Ameera Ali at Sanford Burnham Prebys says she had struggled for years to decide on a career direction, but the internship gave her a fresh perspective on it all.
“Growing up, I never really knew what I wanted to do for a living, and I think that’s because I wanted to do everything. In kindergarten I wanted to be a paleontologist. In 5th grade I wanted to be the CEO of The San Diego Union Tribune, and in 9th grade I wanted to be a physicist at NASA. By 10th grade I was having an existential crisis about what to do with my life, and so began the search for my purpose at the ripe old age of 15.
So now, writing this blog, I never thought I’d end up spending so much of my time in a room filled floor to ceiling with fish tanks. You might be wondering, how does one end up going from physicist to fish farmer? Well, I’m not completely sure to be honest, but it’s been a very fun and interesting experience nonetheless.”
She says by the end she says what initially felt like mundane chores were actually moments worth celebrating.
“These aquatic friends have taught me a lot of valuable life lessons, like being appreciative of the little things in life, caring for others and see things from a different perspective, and realizing that
working in a biology lab allows me to explore my passions, be creative, and be a mother to hundreds of fish children on the side.”
SPARK attracts students from all over California, and it’s that diversity that makes it so important.
Alexa Gastelum
My name is Alexa Gastelum and I am from a small border town called Calexico. It is located in the Imperial Valley around two hours away from San Diego. I found out about this Internship from my Math teacher and Mesa Coordinator. They discussed what it was about, and I immediately knew that I wanted to apply. I have always been interested in doing labs and researching so I knew that it would be the perfect opportunity for me. It is not normal to be presented with an opportunity like this from where I’m from because it is a small and low-income town. When I told my family about this internship they were very supportive. They agreed that I needed to apply for it since it was an extremely good opportunity. Even though I would need to spend my summer away from my hometown, they were okay with it because they knew that I could not miss out on the opportunity. I decided to write my personal statement on a disease that hit close to home with my family which was Alzheimer’s. It is a disease that runs in my family and my uncle passed from it. I believe that this is what sparked my interest because I wanted to understand how it worked and how it affects the brain.
At the SPARK event Alexa told me her grandmother was so proud of her for being accepted at the program that she was going around town telling everyone about it. Her grandmother, and all the other grandmothers and mothers and fathers, had every reason to be proud of these students. They are remarkable young people and we look forward to following their careers in the years to come.
Congratulations to Yasmine Arafa (she/hers), a CIRM Bridges Student Intern at UC Davis Institute for Regenerative Cures! She recently graduated from California State University-Sacramento, officially concluding her Master’s degree and Fulbright Association journey. She conducted research with the aim of developing new therapeutic approaches for rare diseases.
Yasmine says, “I have finally passed my thesis defense and am now a Master‘s degree holder. People in grad school tend to not celebrate their achievements as much, but I chose to celebrate mine.”
“As a graduate student who started their degree in 2020, it has been a rough journey for me. Coming to a new country on my own, away from my family and loved ones, during a pandemic, has been quite the challenge. I‘m proud of myself and of this achievement, because I know the immense amount of academic and mental effort I had to put in to get to this point. To all graduate students out there, don‘t forget to celebrate your success!”
Congrats, Yasmine! She joins 1,663 CIRM Bridges alumni who are helping build the next generation of scientists and meet CIRM’s mission to #AccelerateWorldClassScience here in California for the world.
At the California Institute for Regenerative Medicine (CIRM) we are fortunate in having enough money to fund the most promising research to be tested in a clinical trial. Those are expensive projects, often costing tens of millions of dollars. But sometimes the projects that come to our Board start out years before in much more humble circumstances, raising money through patient advocates, tapping into the commitment and ingenuity of those affected by a disease, to help advance the search for a treatment.
That was definitely the case with a program the CIRM Board voted to approve yesterday, investing more than $11 million dollars to fund a Phase 2 clinical trial testing a cell therapy for dysphagia. That’s a debilitating condition that affects many people treated for head and neck cancer.
Patients with head and neck cancer often undergo surgery and/or radiation to remove the tumors. As a result, they may develop problems swallowing and this can lead to serious complications such as malnutrition, dehydration, social isolation, or a dependence on using a feeding tube. Patients may also inhale food or liquids into their lungs causing infections, pneumonia and death. The only effective therapy is a total laryngectomy where the larynx or voice box is removed, leaving the person unable to speak.
Dr. Peter Belafsky and his team at the University of California at Davis are developing a therapeutic approach using Autologous Muscle Derived Progenitor Cells (AMDC), cells derived from a biopsy of the patient’s own muscle, elsewhere in the body. Those AMDCs are injected into the tongue of the patient, where they fuse with existing muscle fibers to increase tongue strength and ability to swallow.
The $11,015,936 that Dr. Belafsky is getting from CIRM will enable them to test this approach in patients. But without grass roots support the program might never have made it this far.
Ed Steger is a long-term survivor of head and neck cancer, he’s also the President of the National Foundation of Swallowing Disorders (NFOSD). In 2007, after being treated for his cancer, Ed developed a severe swallowing disorder. It helped motivate him to push for better treatment options.
In 2013, a dozen swallowing disorder patients visited UC Davis to learn how stem cells might help people with dysphagia. (You can read about that visit here). Ed says: “We were beyond thrilled with the possibilities and drawing on patients and other UCD contacts our foundation raised enough funds to support a small UCD clinical trial under the guidance of Dr. Belafsky in mouse models that demonstrated these possibilities.”
A few years later that small funding by patients and their family members grew into a well-funded Phase I/II human clinical trial. Ed says the data that trial produced is helping advance the search for treatments.
“Skipping forward to the present, this has now blossomed into an additional $11 million grant, from CIRM, to continue the work that could be a game changer for millions of Americans who suffer annually from oral phase dysphagia. My hat is off to all those that have made this possible… the donors, patient advocates, and the dedicated committed researchers and physicians who are performing this promising and innovative research.”
Our hats are off to them too. Their efforts are making what once might have seemed impossible, a real possibility.
What started out as an effort by Google to crack down on predatory stem cell clinics advertising bogus therapies seems to be getting diluted. Now the concern is whether that will make it easier for these clinics to lure unsuspecting patients to pay good money for bad treatments?
A little background might help here. For years Google placed no restrictions on ads by clinics that claimed their stem cell “therapies” could cure or treat all manner of ailments. Then in September of 2019 Google changed its policy and announced it was going to restrict advertisements for stem cell clinics offering unproven, cellular and gene therapies.
This new policy was welcomed by people like Dr. Paul Knoepfler, a stem cell scientist at UC Davis and longtime critic of these clinics. In his blog, The Niche, he said it was great news:
“Google Ads for stem cell clinics have definitely driven hundreds if not thousands of customers to unproven stem cell clinics. It’s very likely that many of the patients who have ended up in the hospital due to bad outcomes from clinic injections first went to those firms because of Google ads. These ads and certain particularly risky clinics also are a real threat to the legitimate stem cell and gene therapy fields.”
Now the search-engine giant seems to be adjusting that policy. Google says that starting July 11 it will permit ads for stem cell therapies approved by the US Food and Drug Administration (FDA). That’s fine. Anything that has gone through the FDA’s rigorous approval process deserves to be allowed to advertise.
The real concern lies with another adjustment to the policy where Google says it will allow companies to post ads as long as they are “exclusively educational or informational in nature, regardless of regulatory approval status.” The problem is, Google doesn’t define what constitutes “educational or informational”. That leaves the door open for these clinics to say pretty much anything they want and claim it meets the new guidelines.
To highlight that point Gizmodo did a quick search on Google using the phrase “stem cells for neuropathy” and quickly came up with a series of ads that are offering “therapies” clearly not approved by the FDA. One ad claimed it was “FDA registered”, a meaningless phrase but one clearly designed to add an air of authenticity to whatever remedy they were peddling.
The intent behind Google’s change of policy is clearly good, to allow companies offering FDA-approved therapies to advertise. However, the outcome may not be quite so worthy, and might once again put patients at risk of being tricked into trying “therapies” that will almost certainly not do them any good, and might even put them in harm’s way.
