These last few days have been interesting on so many levels. First the presidential race has kept the nation on tenterhooks. Closer to home the vote count for Proposition 14, to refunded CIRM, has been painstakingly slow (by the way, painstakingly means “with great care and thoroughness” for which we thank all the vote counters). But now, finally, happily, we have a verdict.
It was close, desperately so. In the end the Associated Press called the race with the count at 51% yes, to 49% no. You can understand why so many of us were so nervous for so long. But now we have something to celebrate.
As Jonathan Thomas, JD, PhD, the Chair of our Board said: “We are thrilled to see Proposition 14 approved by the voters of California. We are proud of what we have achieved so far – the cures and therapies we helped develop, the billions we brought into the state in additional investments, and the tens of thousands of jobs we created – and we look forward to continuing that work.
“We are honored by the trust the people of California have placed in us, and by the support of our extraordinary patient advocate community and by the many Chambers of Commerce around California who have all recognized our historic achievements.
“We are already working on ways to repay that trust and bring stem cell and regenerative therapies to all the people of this great state, particularly for communities that have traditionally been overlooked or underserved.”
In a news release on the Californians for Cures website, Bob and Danielle Klein, who led the Yes on 14 campaign, were understandably delighted:
“The success of Prop. 14 sends a clear message from California voters that one of the most important investments our state can make is in the future health of our families. Over the past decade, California has made incredibly thoughtful and impactful investments in developing stem cell therapies and cures for diseases and conditions like diabetes, cancer, blindness, Parkinson’s, paralysis and many more; now we know this progress and work to mitigate human suffering, restore health and improve the human condition will continue. A special thank you to California’s voters and our supporters in passing this critical measure. Today would not have been possible without our historically unprecedented coalition of patient advocate organizations and individuals – the heart and soul of this campaign – who worked tirelessly to overcome all obstacles and help secure a victory for patients and their families, and deliver hope to those searching for a cure for generations to come.”
To all of you who voted for us, thank you from the bottom of our hearts.
To all the people who worked so hard to get Prop 14 passed, thank you. We are indebted to you.
The gold standard for any new therapy in the U.S. is approval by the Food and Drug Administration (FDA). This approval clears the therapy for sale and often also means it will be covered by insurance. But along the way there are other designations that can mean a lot to a company developing a new approach to a deadly disease.
That’s what recently happened with Mustang Bio’s MB-107. The therapy was given Orphan Drug Designation for the treatment of X-linked Severe Combined Immunodeficiency (SCID) also known as “bubble baby disease”, a rare but deadly immune disorder affecting children. This is the same therapy that CIRM is funding in a clinical trial we’ve blogged about in the past.
Getting Orphan Drug Designation can be a big deal. It is given to therapies intended for the treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the U.S. It comes with some sweet incentives, such as tax credits toward the cost of clinical trials and prescription drug user fee waivers. And, if the product becomes the first in its class to get FDA approval for a particular disease, it is entitled to seven years of market exclusivity, which is independent from intellectual property protection.
This is not the first time Mustang Bio’s MB-107 has been acknowledged as a potential gamechanger. It’s also been given three other classifications both here in the US and in Europe.
Rare Pediatric Disease Designation: this also applies to treatments for diseases affecting fewer than 200,000 people in the US that have the potential to provide clinically meaningful benefits to patients. It provides the company with a “voucher” that they can use to apply for priority review for another therapy they are developing. The hope is that this will encourage companies to develop treatments for rare childhood diseases that might not otherwise be profitable.
Regenerative Medicine Advanced Therapy (RMAT) designation: this allows for faster, more streamlined approvals of regenerative medicine products
Advanced Therapy Medicinal Product classification: this is granted by the European Medicines Agency (EMA) to medicines that are based on genes, tissues or cells and can offer groundbreaking opportunities for the treatment of disease.
Of course, none of these designations are a guarantee that Mustang Bio’s MB-107 will ultimately get FDA approval, but they’re a pretty good indication that a lot of people have confidence they’ll get there.
Funding models are rarely talked about in excited tones. It’s normally relegated to the dry tomes of academia. But in CIRM’s case, the funding model we have created is not just fundamental to our success in advancing regenerative medicine in California, it’s also proving to be a model that many other agencies are looking at to see if they can replicate it.
A recent article in the journal Cell & Gene Therapy Insights looks at what the CIRM model does and how it has achieved something rather extraordinary.
Full disclosure. I might be a tad biased here as the article was written by my boss, Dr. Maria Millan, and two of my colleagues, Dr. Sohel Talib and Dr. Shyam Patel.
I won’t go into huge detail here (you can get that by reading the article itself) But the article “highlights 3 elements of CIRM’s funding model that have enabled California academic researchers and companies to de-risk development of novel regenerative medicine therapies and attract biopharma industry support.”
Those three elements are:
1. Ensuring that funding mechanisms bridge the entire translational “Valley of Death”
2. Constantly optimizing funding models to meet the needs of a rapidly evolving industry
3. Championing the portfolio and proactively engaging potential industry partners
As an example of the first, they point to our Disease Team awards. These were four-year investments that gave researchers with promising projects the time, support and funds they needed to not only develop a therapy, but also move it out of academia into a company and into patients. Many of these projects had struggled to get outside investment until CIRM stepped forward. One example they offer is this one.
“CIRM Disease Team award funding also enabled Dr. Irving Weissman and the Stanford University team to discover, develop and obtain first-in-human clinical data for the innovative anti-CD47 antibody immunotherapy approach to cancer. The spin-out, Forty Seven, Inc., then leveraged CIRM funding as well as venture and public market financing to progress clinical development of the lead candidate until its acquisition by Gilead Sciences in April 2020 for $4.9B.”
But as the field evolved it became clear CIRM’s funding model had to evolve too, to better meet the needs of a rapidly advancing industry. So, in 2015 we changed the way we worked. For example, with clinical trial stage projects we reduced the average time from application to funding from 22 months to 120 days. In addition to that applications for new clinical stage projects were able to be submitted year-round instead of only once or twice a year as in the past.
We also created hard and fast milestones for all programs to reach. If they met their milestone funding continued. If they didn’t, funding stopped. And we required clinical trial stage projects, and those for earlier stage for-profit companies, to put up money of their own. We wanted to ensure they had “skin in the game” and were as committed to the success of their project as we were.
Finally, to champion the portfolio we created our Industry Alliance Program. It’s a kind of dating program for the researchers CIRM funds and companies looking to invest in promising projects. Industry partners get a chance to look at our portfolio and pick out projects they think are interesting. We then make the introductions and see if we can make a match.
And we have.
“To date, the IAP has also formally enrolled 8 partners with demonstrated commitment to cell and gene therapy development. The enrolled IAP partners represent companies both small and large, multi-national venture firms and innovative accelerators.
Over the past 18 months, the IAP program has enabled over 50 one-on-one partnership interactions across CIRM’s portfolio from discovery stage pluripotent stem cell therapies to clinical stage engineered HSC therapies.”
As the field continues to mature there are new problems emerging, such as the need to create greater manufacturing capacity to meet the growth in demand for high quality stem cell products. CIRM, like all other agencies, will also have to evolve and adapt to these new demands. But we feel with the model we have created, and the flexibility we have to pivot when needed, we are perfectly situated to do just that.
Battling the virus that causes COVID-19 is something that is top of everyone’s mind right now. That’s why CIRM is funding 17 different projects targeting the virus. But one of the most valuable tools in helping develop vaccines against a wide variety of diseases in the past is now coming under threat. We’ll talk about both issues in a live broadcast we’re holding on Wednesday, October 14th at noon (PDT).
That date is significant because it’s Stem Cell Awareness Day and we thought it appropriate to host a meeting looking at two of the most important issues facing the field.
The first part of the event will focus on the 17 projects that CIRM is funding that target COVID-19. This includes three clinical trials aiming to treat people who have been infected with the virus and are experiencing some of the more severe effects, such as damaged lungs.
We’ll also look at some of the earlier stage research that includes:
Work to help develop a vaccine
Using muscle stem cells to help repair damage to the diaphragm in patients who have spent an extended period on a ventilator
Boosting immune system cells to help fight the virus
The second part of the event will look at ways that funding for stem cell research at the federal level is once again coming into question. The federal government has already imposed new restrictions on funding for fetal tissue research, and now there are efforts in Congress to restrict funding for embryonic stem cell research.
The impacts could be significant. Fetal tissue has been used for decades to help develop some of the most important vaccines used today including rubella, chickenpox, hepatitis A, and shingles. They have also been used to make approved drugs against diseases including hemophilia, rheumatoid arthritis, and cystic fibrosis.
We’ll look at some of the reasons why we are seeing these potential restrictions on the medical research and what impact they could have on the ability to develop new treatments for the coronavirus and other deadly diseases.
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.
We are at a turning point in regenerative medicine as the first wave of treatments have obtained FDA approval. But at the same time as we see the advance of scientifically rigorous research and regulated products we are also witnessing the continued proliferation of “unproven treatments.” This dueling environment can be overwhelming and distracting to individuals and families trying to manage life-threatening diseases.
How does a patient navigate this environment and get trusted and reliable information to help sort through their options?
CIRM teamed up with the CURA Foundation to organize a roundtable discussion intended to answer this question. The conversation included thought leaders involved in patient advocacy, therapy research and development, public policy and research funding. The roundtable was divided into three segments designed to discuss:
Examples of state-of-the-art patient navigation systems,
Policy, research and infrastructure needs required to expand navigation systems, and
Communication needs for engaging patients and the broader community.
Examples of Navigation Systems:
This session was framed around the observation that patients often do not get the best medicines or treatments available for their condition. For example, in the area of cancer care there is evidence that the top 25% of cancers are not being treated optimally. Historic barriers to optimal treatment include cost pressures that may block access to treatments, lack of knowledge about the available treatments or the absence of experts in the location where the patient is being treated. Much of the session focused on how these barriers are being overcome by partnerships between health care provides, employers and patients.
For example, new technologies such as DNA sequencing and other cell-based markers enable better diagnosis of a patient’s underlying disease. This information can be collected by a community hospital and shared with experts who work with the treating doctor to consider the best options for the patient. If patients need to access a specialty center for treatment, there are new models for the delivery of such care. Emphasis is placed on building a relationship with the patient and their family by surrounding them with a team that can address any questions that arise. The model of patient-centered care is being embraced by employers who are purchasing suites of services for their employees.
Patient advocacy groups have also supported efforts to get the best information about the patients’ underlying disease. Advocacy organizations have been building tools to connect patients with researchers with the aim of allowing secure and responsible sharing of medical information to drive the patient-centered development of new treatments. In a related initiative, the American Society of Hematology is creating a data hub for clinical trials for sickle cell disease. Collectively, these efforts are designed to accelerate new treatments by allowing critical data to be shared among researchers.
Essential Policy Infrastructure for Regenerative Medicine:
Session two dovetailed nicely with first discussion. There was continued emphasis on the need for additional evidence (data) to demonstrate that regenerative medicine treatments are having a significant effect on the patient’s disease. Various speakers echoed the need for patients in clinical trials to work with researchers to determine the benefits of treatments. Success stories with gene therapies in blood diseases were cited as proof of concept where treatments being evaluated in clinical trials are demonstrating a significant and sustained impact on diseases. Evidence of benefit is needed by both regulatory bodies that approve the treatments, such as the FDA, and by public and private payers / insurers that pay for treatments and patients that need to know the best option for their particular disease.
In addition, various speakers cited the continued proliferation of “unproven treatments” being marketed by for-profit centers. There was broad concern that the promotion of treatment where there is no evidence of effectiveness will mislead some patients and potentially harm the scientifically rigorous development of new treatments. Particularly for “stem cell” treatments, there was a desire to develop evaluation criteria that are clear and transparent to allow legitimate treatments to be distinguished from those with no evidence of effectiveness. One participant suggested there be a scorecard approach where specific treatments could be rated against specific indicators of safety, medical benefit and value in relation to alternative treatments. The idea would be to make this information widely available to patients, medical providers and the public to inform everything from medical decision making to advertising.
Communicating the Vision
The final session considered communication needs for the field of regenerative medicine. Patients and patient advocacy organizations described how they are using social media and other networking tools to share information and experiences in navigating their treatment options. Patient advocacy groups also described the challenges from providers of unproven treatments. In one case, a for profit “pop up” clinic had used the group’s videos in an attempt to legitimize their unproven treatment.
There was general consensus among the panelists that the field of regenerative medicine needs “trusted intermediaries” who can evaluate claims and help patients distinguish between high quality research and “snake oil”. These intermediaries should have the capacity to compile the most reliable evidence and utilize it to determine what options are available to patients. In addition, there needs to be shared decision making model where patients have the opportunity to explore options in an unbiased environment so they may make the best decision based on their specific needs and values.
Creating this kind of Navigation System will not be easy but the alternative is unacceptable. Too many vulnerable patients are being taken advantage of by the growing number of “predatory clinics” hawking expensive therapies that are both unproven and unapproved. We owe it to these patients to create a simple way for them to identify what are the most promising therapies, ones that have the highest chance of being both safe and effective. The roundtable discussion marked a starting point, bringing together many of the key players in the field, highlighting the key issues and beginning to identify possible solutions.
The briefing is a traditional kick-off event to mark JP Morgan week in the City, a time when hotel rooms go for $1,000 a night and just reserving a table in the lobby for meetings can set you back hundreds of dollars. Fortunately, the ARM briefing is free. And worth every penny.
987 companies world wide – most of those in the US
1,000 + clinical trials
$9.8 billion in revenue/investments
Saying “for many of these patients these therapies don’t just bring improvements, they bring dramatic improvements” Lambert pointed out that when those 1,000 clinical trials are fully enrolled it will mean 60,000 patients getting stem cell and gene therapies. She says it’s estimated that in the coming years around half a million patients in the US alone will get one of those therapies.
More and more of the clinical trials are at advanced stages:
100 Phase 3
591 Phase 2
381 Phase 1
The biggest sector for clinical trials is cancer, but there are also substantial numbers for central nervous system therapies, muscular skeletal and even rare diseases.
Lambert said there are two key issues facing the field in the coming year. One is improving the industry’s manufacturing capability to ensure we are able to produce the cells needed to treat large numbers of patients. As evidence she cited the fact that Pfizer and Novartis are investing hundreds of millions of dollars in in-house manufacturing facilities.
The second key issue is reimbursement, so that companies can get paid for delivering those treatments to patients. “There is appetite and interest in this from people around the world, but right now most conversations about reimbursement are taking place one at a time. We haven’t yet evolved to the point where we have standard models to help get products to market and help them be commercially successful.”
The forecast for the year ahead? “Sunny with some clouds. 2019 was a year of significant growth and we enter 2020 with hopes of continued expansion, as we look to grow the impact on patients.”
As we get close to the end of the year there is no shortage of lists of the “best of the year” and even this year the “best of the decade”. But when it comes to podcasts it would be hard to think of a better one than “Bad Batch”. It’s part stem cell research, part medical mystery and altogether engrossing.
It’s the work of Laura Beil, an award-winning journalist who follows the trail of a stem cell therapy that was supposed to help patients but instead left them battling life-threatening infections. It highlights how some clinics are able to find loopholes in the law that allow them to offer unproven and unapproved therapies, and how those therapies can put people’s lives at risk.
We have written about the dangers of predatory stem cell clinics several times, but in “Bad Batch” you get to hear the voices of the people affected, and ultimately the people responsible. It’s great journalism and fascinating story telling. And it’s a reminder of the work that needs to be done to stop this ever happening again.
On December 12th we hosted our latest ‘Facebook Live: Ask the Stem Cell Team’ event. This time around we really did mean team. We had a host of our Science Officers answering questions from friends and supporters of CIRM. We got a lot of questions and didn’t have enough time to address them all. So here’s answers to all the questions.
What are the obstacles to using partial cellular reprogramming to return people’s entire bodies to a youthful state.Paul Hartman. San Leandro, California
Dr. Kelly Shepard: Certainly, scientists have observed that various manipulations of cells, including reprogramming, partial reprogramming, de-differentiation and trans-differentiation, can restore or change properties of cells, and in some cases, these changes can reflect a more “youthful” state, such as having longer telomeres, better proliferative capacity, etc. However, some of these same rejuvenating properties, outside of their normal context, could be harmful or deadly, for example if a cell began to grow and divide when or where it shouldn’t, similar to cancer. For this reason, I believe the biggest obstacles to making this approach a reality are twofold: 1) our current, limited understanding of the nature of partially reprogrammed cells; and 2) our inability to control the fate of those cells that have been partially reprogrammed, especially if they are inside a living organism. Despite the challenges, I think there will be step wise advances where these types of approaches will be applied, starting with specific tissues. For example, CIRM has recently funded an approach that uses reprogramming to make “rejuvenated” versions of T cells for fighting lung cancer. There is also a lot of interest in using such approaches to restore the reparative capacity of aged muscle. Perhaps some successes in these more limited areas will be the basis for expanding to a broader use.
What’s going on with Stanford’s stem cell trials for stroke? I remember the first trial went really well In 2016 have not heard anything about since? Elvis Arnold
Dr. Lila Collins: Hi Elvis, this is an evolving story. I believe you are referring to SanBio’s phase 1/2a stroke trial, for which Stanford was a site. This trial looked at the safety and feasibility of SanBio’s donor or allogeneic stem cell product in chronic stroke patients who still had motor deficits from their strokes, even after completing physical therapy when natural recovery has stabilized. As you note, some of the treated subjects had promising motor recoveries.
SanBio has since completed a larger, randomized phase 2b trial in stroke, and they have released the high-level results in a press release. While the trial did not meet its primary endpoint of improving motor deficits in chronic stroke, SanBio conducted a very similar randomized trial in patients with stable motor deficits from chronic traumatic brain injury (TBI). In this trial, SanBio saw positive results on motor recovery with their product. In fact, this product is planned to move towards a conditional approval in Japan and has achieved expedited regulatory status in the US, termed RMAT, in TBI which means it could be available more quickly to patients if all goes well. SanBio plans to continue to investigate their product in stroke, so I would stay tuned as the work unfolds.
Also, since you mentioned Stanford, I should note that Dr Gary Steinberg, who was a clinical investigator in the SanBio trial you mentioned, will soon be conducting a trial with a different product that he is developing, neural progenitor cells, in chronic stroke. The therapy looks promising in preclinical models and we are hopeful it will perform well for patients in the clinic.
I am a stroke survivor will stem cell treatment able to restore my motor skills?Ruperto
Dr. Lila Collins:
Hi Ruperto. Restoring motor loss after stroke is a very active area of research. I’ll touch upon a few ongoing stem cell trials. I’d just like to please advise that you watch my colleague’s comments on stem cell clinics (these can be found towards the end of the blog) to be sure that any clinical research in which you participate is as safe as possible and regulated by FDA.
Back to stroke, I mentioned SanBio’s ongoing work to address motor skill loss in chronic stroke earlier. UK based Reneuron is also conducting a phase 2 trial, using a neural progenitor cell as a candidate therapy to help recover persistent motor disability after stroke (chronic). Dr Gary Steinberg at Stanford is also planning to conduct a clinical trial of a human embryonic stem cell-derived neuronal progenitor cell in stroke.
There is also promising work being sponsored by Athersys in acute stroke. Athersys published results from their randomized, double blinded placebo controlled Ph2 trial of their Multistem product in patients who had suffered a stroke within 24-48 hours. After intravenous delivery, the cells improved a composite measure of stroke recovery, including motor recovery. Rather than acting directly on the brain, Multistem seems to work by traveling to the spleen and reducing the inflammatory response to a stroke that can make the injury worse.
Athersys is currently recruiting a phase 3 trial of its Multistem product in acute stroke (within 1.5 days of the stroke). The trial has an accelerated FDA designation, called RMAT and a special protocol assessment. This means that if the trial is conducted as planned and it reaches the results agreed to with the FDA, the therapy could be cleared for marketing. Results from this trial should be available in about two years.
Questions from several hemorrhagic stroke survivors who say most clinical trials are for people with ischemic strokes. Could stem cells help hemorrhagic stroke patients as well?
Dr. Lila Collins:
Regarding hemorrhagic stroke, you are correct the bulk of cell therapies for stroke target ischemic stroke, perhaps because this accounts for the vast bulk of strokes, about 85%.
That said, hemorrhagic strokes are not rare and tend to be more deadly. These strokes are caused by bleeding into or around the brain which damages neurons. They can even increase pressure in the skull causing further damage. Because of this the immediate steps treating these strokes are aimed at addressing the initial bleeding insult and the blood in the brain.
While most therapies in development target ischemic stroke, successful therapies developed to repair neuronal damage or even some day replace lost neurons, could be beneficial after hemorrhagic stroke as well.
I had an Ischemic stroke in 2014, and my vision was also affected. Can stem cells possibly help with my vision issues. James Russell
Dr. Lila Collins:
Hi James. Vision loss from stroke is complex and the type of loss depends upon where the stroke occurred (in the actual eye, the optic nerve or to the other parts of the brain controlling they eye or interpreting vision). The results could be:
Visual loss from damage to the retina
You could have a normal eye with damage to the area of the brain that controls the eye’s movement
You could have damage to the part of the brain that interprets vision.
You can see that to address these various issues, we’d need different cell replacement approaches to repair the retina or the parts of the brain that were damaged.
Replacing lost neurons is an active effort that at the moment is still in the research stages. As you can imagine, this is complex because the neurons have to make just the right connections to be useful.
Is there any stem cell therapy for optical nerve damage? Deanna Rice
Dr. Ingrid Caras: There is currently no proven stem cell therapy to treat optical nerve damage, even though there are shady stem cell clinics offering treatments. However, there are some encouraging early gene therapy studies in mice using a virus called AAV to deliver growth factors that trigger regeneration of the damaged nerve. These studies suggest that it may be possible to restore at least some visual function in people blinded by optic nerve damage from glaucoma
I read an article about ReNeuron’s retinitis pigmentosa clinical trial update. In the article, it states: “The company’s treatment is a subretinal injection of human retinal progenitors — cells which have almost fully developed into photoreceptors, the light-sensing retinal cells that make vision possible.” My question is: If they can inject hRPC, why not fully developed photoreceptors?Leonard
Dr. Kelly Shepard: There is evidence from other studies, including from other tissue types such as blood, pancreas, heart and liver, that fully developed (mature) cell types tend not to engraft as well upon transplantation, that is the cells do not establish themselves and survive long term in their new environment. In contrast, it has been observed that cells in a slightly less “mature” state, such as those in the progenitor stage, are much more likely to establish themselves in a tissue, and then differentiate into more mature cell types over time. This question gets at the crux of a key issue for many new therapies, i.e. what is the best cell type to use, and the best timing to use it.
My question for the “Ask the Stem Cell Team” event is: When will jCyte publish their Phase IIb clinical trial results. Chris Allen
Dr. Ingrid Caras: The results will be available sometime in 2020.
I understand the hRPC cells are primarily neurotropic (rescue/halt cell death); however, the literature also says hRPC can become new photoreceptors. My questions are:Approximately what percentage develop into functioning photoreceptors? And what percentage of the injected hRPC are currently surviving?Leonard Furber, an RP Patient
Dr. Kelly Shepard: While we can address these questions in the lab and in animal models, until there is a clinical trial, it is not possible to truly recreate the environment and stresses that the cells will undergo once they are transplanted into a human, into the site where they are expected to survive and function. Thus, the true answer to this question may not be known until after clinical trials are performed and the results can be evaluated. Even then, it is not always possible to monitor the fate of cells after transplantation without removing tissues to analyze (which may not be feasible), or without being able to transplant labeled cells that can be readily traced.
Dr. Ingrid Caras – Although the cells have been shown to be capable of developing into photoreceptors, we don’t know if this actually happens when the cells are injected into a patient’s eye. The data so far suggest that the cells work predominantly by secreting growth factors that rescue damaged retinal cells or even reverse the damage. So one possible outcome is that the cells slow or prevent further deterioration of vision. But an additional possibility is that damaged retinal cells that are still alive but are not functioning properly may become healthy and functional again which could result in an improvement in vision.
What advances have been made using stem cells for the treatment of Type 2 Diabetes?Mary Rizzo
Dr. Ross Okamura: Type 2 Diabetes (T2D) is a disease where the body is unable to maintain normal glucose levels due to either resistance to insulin-regulated control of blood sugar or insufficient insulin production from pancreatic beta cells. The onset of disease has been associated with lifestyle influenced factors including body mass, stress, sleep apnea and physical activity, but it also appears to have a genetic component based upon its higher prevalence in certain populations.
Type 1 Diabetes (T1D) differs from T2D in that in T1D patients the pancreatic beta cells have been destroyed by the body’s immune system and the requirement for insulin therapy is absolute upon disease onset rather than gradually developing over time as in many T2D cases. Currently the only curative approach to alleviate the heavy burden of disease management in T1D has been donor pancreas or islet transplantation. However, the supply of donor tissue is small relative to the number of diabetic patients. Donor islet and pancreas transplants also require immune suppressive drugs to prevent allogenic immune rejection and the use of these drugs carry additional health concerns. However, for some patients with T1D, especially those who may develop potentially fatal hypoglycemia, immune suppression is worth the risk.
To address the issue of supply, there has been significant activity in stem cell research to produce insulin secreting beta cells from pluripotent stem cells and recent clinical data from Viacyte’s CIRM funded trial indicates that implanted allogeneic human stem cell derived cells in T1D patients can produce circulating c-peptide, a biomarker for insulin. While the trial is not designed specifically to cure insulin-dependent T2D patients, the ability to produce and successfully engraft stem cell-derived beta cells would be able to help all insulin-dependent diabetic patients.
It’s also worth noting that there is a sound scientific reason to clinically test a patient-derived pluripotent stem cell-based insulin-producing cells in insulin-dependent T2D diabetic patients; the cells in this case could be evaluated for their ability to cure diabetes in the absence of needing to prevent both allogeneic and autoimmune responses.
SPINAL CORD INJURY
Is there any news on clinical trials for spinal cord injury? Le Ly
Kevin McCormack: The clinical trial CIRM was funding, with Asterias (now part of a bigger company called Lineage Cell Therapeutics, is now completed and the results were quite encouraging. In a news release from November of 2019 Brian Culley, CEO of Lineage Cell Therapeutics, described the results this way.
“We remain extremely excited about the potential for OPC1 (the name of the therapy used) to provide enhanced motor recovery to patients with spinal cord injuries. We are not aware of any other investigative therapy for SCI (spinal cord injury) which has reported as encouraging clinical outcomes as OPC1, particularly with continued improvement beyond 1 year. Overall gains in motor function for the population assessed to date have continued, with Year 2 assessments measuring the same or higher than at Year 1. For example, 5 out of 6 Cohort 2 patients have recovered two or more motor levels on at least one side as of their Year 2 visit whereas 4 of 6 patients in this group had recovered two motor levels as of their Year 1 visit. To put these improvements into perspective, a one motor level gain means the ability to move one’s arm, which contributes to the ability to feed and clothe oneself or lift and transfer oneself from a wheelchair. These are tremendously meaningful improvements to quality of life and independence. Just as importantly, the overall safety of OPC1 has remained excellent and has been maintained 2 years following administration, as measured by MRI’s in patients who have had their Year 2 follow-up visits to date. We look forward to providing further updates on clinical data from SCiStar as patients continue to come in for their scheduled follow up visits.”
Lineage Cell Therapeutics plans to meet with the FDA in 2020 to discuss possible next steps for this therapy.
In the meantime the only other clinical trial I know that is still recruiting is one run by a company called Neuralstem. Here is a link to information about that trial on the www.clinicaltrials.gov website.
Now that the Brainstorm ALS trial is finished looking for new patients do you have any idea how it’s going and when can we expect to see results? Angela Harrison Johnson
Dr. Ingrid Caras: The treated patients have to be followed for a period of time to assess how the therapy is working and then the data will need to be analyzed. So we will not expect to see the results probably for another year or two.
Are there treatments for autism or fragile x using stem cells? Magda Sedarous
Dr. Kelly Shepard: Autism and disorders on the autism spectrum represent a collection of many different disorders that share some common features, yet have different causes and manifestations, much of which we still do not understand. Knowing the origin of a disorder and how it affects cells and systems is the first step to developing new therapies. CIRM held a workshop on Autism in 2009 to brainstorm potential ways that stem cell research could have an impact. A major recommendation was to exploit stem cells and new technological advances to create cells and tissues, such as neurons, in the lab from autistic individuals that could then be studied in great detail. CIRM followed this recommendation and funded several early-stage awards to investigate the basis of autism, including Rett Syndrome, Fragile X, Timothy Syndrome, and other spectrum disorders. While these newer investigations have not yet led to therapies that can be tested in humans, this remains an active area of investigation. Outside of CIRM funding, we are aware of more mature studies exploring the effects of umbilical cord blood or other specific stem cell types in treating autism, such as an ongoing clinical trial conducted at Duke University.
What is happening with Parkinson’s research? Hanifa Gaphoor
Dr. Kent Fitzgerald: Parkinson’s disease certainly has a significant amount of ongoing work in the regenerative medicine and stem cell research.
The nature of cell loss in the brain, specifically the dopaminergic cells responsible for regulating the movement, has long been considered a good candidate for cell replacement therapy.
This is largely due to the hypothesis that restoring function to these cells would reverse Parkinson’s symptoms. This makes a lot of sense as front line therapy for the disease for many years has been dopamine replacement through L-dopa pills etc. Unfortunately, over time replacing dopamine through a pill loses its benefit, whereas replacing or fixing the cells themselves should be a more permanent fix.
Because a specific population of cells in one part of the brain are lost in the disease, multiple labs and clinicians have sought to replace or augment these cells by transplantation of “new” functional cells able to restore function to the area an theoretically restore voluntary motor control to patients with Parkinson’s disease.
Early clinical research showed some promise, however also yielded mixed results, using fetal tissue transplanted into the brains of Parkinson’s patients. As it turns out, the cell types required to restore movement and avoid side effects are somewhat nuanced. The field has moved away from fetal tissue and is currently pursuing the use of multiple stem cell types that are driven to what is believed to be the correct subtype of cell to repopulate the lost cells in the patient.
One project CIRM sponsored in this area with Jeanne Loring sought to develop a cell replacement therapy using stem cells from the patients themselves that have been reprogrammed into the kinds of cell damaged by Parkinson’s. This type of approach may ultimately avoid issues with the cells avoiding rejection by the immune system as can be seen with other types of transplants (i.e. liver, kidney, heart etc).
Still, others are using cutting edge gene therapy technology, like the clinical phase project CIRM is sponsoring with Krystof Bankiewicz to investigate the delivery of a gene (GDNF) to the brain that may help to restore the activity of neurons in the Parkinson’s brain that are no longer working as they should.
The bulk of the work in the field of PD at the present remains centered on replacing or restoring the dopamine producing population of cells in the brain that are affected in disease.
Any plans for Huntington’s?Nikhat Kuchiki
Dr. Lisa Kadyk: The good news is that there are now several new therapeutic approaches to Huntington’s Disease that are at various stages of preclinical and clinical development, including some that are CIRM funded. One CIRM-funded program led by Dr. Leslie Thompson at UC Irvine is developing a cell-based therapeutic that consists of neural stem cells that have been manufactured from embryonic stem cells. When these cells are injected into the brain of a mouse that has a Huntington’s Disease mutation, the cells engraft and begin to differentiate into new neurons. Improvements are seen in the behavioral and electrophysiological deficits in these mutant mice, suggesting that similar improvements might be seen in people with the disease. Currently, CIRM is funding Dr. Thompson and her team to carry out rigorous safety studies in animals using these cells, in preparation for submitting an application to the FDA to test the therapy in human patients in a clinical trial.
There are other, non-cell-based therapies also being tested in clinical trials now, using anti-sense oligonucleotides (Ionis, Takeda) to lower the expression of the Huntington protein. Another HTT-lowering approach is similar – but uses miRNAs to lower HTT levels (UniQure,Voyager)
TRAUMATIC BRAIN INJURY (TBI)
My 2.5 year old son recently suffered a hypoxic brain injury resulting in motor and speech disabilities. There are several clinical trials underway for TBI in adults. My questions are:
Will the results be scalable to pediatric use and how long do you think it would take before it is available to children?
I’m wondering why the current trials have chosen to go the route of intracranial injections as opposed to something slightly less invasive like an intrathecal injection?
Is there a time window period in which stem cells should be administered by, after which the administration is deemed not effective?
Dr. Kelly Shepard: TBI and other injuries of the nervous system are characterized by a lot of inflammation at the time of injury, which is thought to interfere with the healing process- and thus some approaches are intended to be delivered after that inflammation subsides. However, we are aware of approaches that intend to deliver a therapy to a chronic injury, or one that has occurred previously. Thus, the answer to this question may depend on how the intended therapy is supposed to work. For example, is the idea to grow new neurons, or is it to promote the survival of neurons of other cells that were spared by the injury? Is the therapy intended to address a specific symptom, such as seizures? Is the therapy intended to “fill a gap” left behind after inflammation subsides, which might not restore all function but might ameliorate certain symptoms.? There is still a lot we don’t understand about the brain and the highly sophisticated network of connections that cannot be reversed by only replacing neurons, or only reducing inflammation, etc. However, if trials are well designed, they should yield useful information even if the therapy is not as effective as hoped, and this information will pave the way to newer approaches and our technology and understanding evolves.
We have had a doctor recommending administering just the growth factors derived from MSC stem cells. Does the science work that way? Is it possible to isolate the growth factors and boost the endogenous growth factors by injecting allogenic growth factors?
Dr. Stephen Lin: Several groups have published studies on the therapeutic effects in non-human animal models of using nutrient media from MSC cultures that contain secreted factors, or extracellular vesicles from cells called exosomes that carry protein or nucleic acid factors. Scientifically it is possible to isolate the factors that are responsible for the therapeutic effect, although to date no specific factor or combination of factors have been identified to mimic the effects of the undefined mixtures in the media and exosomes. At present no regulatory approved clinical therapy has been developed using this approach.
PREDATORY STEM CELL CLINICS
What practical measures are being taken to address unethical practitioners whose bad surgeries are giving stem cell advances a bad reputation and are making forward research difficult?Kathy Jean Schultz
Dr. Geoff Lomax: Terrific question! I have been doing quite a bit research into the history of this issue of unethical practitioners and I found an 1842 reference to “quack medicines.” Clearly this is nothing new. In that day, the author appealed to make society “acquainted with the facts.”
In California, we have taken steps to (1) acquaint patients with the facts about stem cell treatments and (2) advance FDA authorized treatments for unmet medical needs.
First, CIRM work with Senator Hernandez in 2017 to write a law the requires provides to disclose to patient that a stem cell therapy has not been approved by the Food and Drug administration.
We continue to work with the State Legislature and Medical Board of California to build on policies that require accurate disclosure of the facts to patients.
Second, our clinical trial network the — Alpha Stem Cell Clinics – have supported over 100 FDA-authorized clinical trials to advance responsible clinical research for unmet medical needs.
I’m curious if adipose stem cell being used at clinics at various places in the country is helpful or beneficial?Cheri Hicks
Adipose tissue has been widely used particularly in plastic and reconstructive surgery. Many practitioners suggest adipose cells are beneficial in this context. With regard to regenerative medicine and / or the ability to treat disease and injury, I am not aware of any large randomized clinical trials that demonstrate the safety and efficacy of adipose-derived stem cells used in accordance with FDA guidelines.
I went to a “Luncheon about Stem Cell Injections”. It sounded promising. I went thru with it and got the injections because I was desperate from my knee pain. The price of stem cell injections was $3500 per knee injection. All went well. I have had no complications, but haven’t noticed any real major improvement, and here I am a year later. My questions are:
1) I wonder on where the typical injection cells are coming from?
2) I wonder what is the actual cost of the cells?
3) What kind of results are people getting from all these “pop up” clinics or established clinics that are adding this to there list of offerings?
Dr. Geoff Lomax: You raise a number of questions and point here; they are all very good and it’s is hard to give a comprehensive response to each one, but here is my reaction:
There are many practitioners in the field of orthopedics who sincerely believe in the potential of cell-based treatments to treat injury / pain
Most of the evidence presented is case reports that individuals have benefited
The challenge we face is not know the exact type of injury and cell treatments used.
Well controlled clinical trials would really help us understand for what cells (or cell products) and for what injury would be helpful
Prices of $3000 to $5000 are not uncommon, and like other forms of private medicine there is often a considerable mark-up in relation to cost of goods.
You are correct that there have not been reports of serious injury for knee injections
However the effectiveness is not clear while simultaneously millions of people have been aided by knee replacements.
Do stem cells have benefits for patients going through chemotherapy and radiation therapy?Ruperto
Dr. Kelly Shepard: The idea that a stem cell therapy could help address effects of chemotherapy or radiation is being and has been pursued by several investigators over the years, including some with CIRM support. Towards the earlier stages, people are looking at the ability of different stem cell-derived neural cell preparations to replace or restore function of certain brain cells that are damaged by the effects of chemotherapy or radiation. In a completely different type of approach, a group at City of Hope is exploring whether a bone marrow transplant with specially modified stem cells can provide a protective effect against the chemotherapy that is used to treat a form of brain cancer, glioblastoma. This study is in the final stage of development that, if all goes well, culminates with application to the FDA to allow initiation of a clinical trial to test in people.
Dr. Ingrid Caras: That’s an interesting and valid question. There is a Phase 1 trial ongoing that is evaluating a novel type of stem/progenitor cell from the umbilical cord of healthy deliveries. In animal studies, these cells have been shown to reduce the toxic effects of chemotherapy and radiation and to speed up recovery. These cells are now being tested in a First-in-human clinical trial in patients who are undergoing high-dose chemotherapy to treat their disease.
There is a researcher at Stanford, Michelle Monje, who is investigating that the role of damage to stem cells in the cognitive problems that sometimes arise after chemo- and radiation therapy (“chemobrain”). It appears that damage to stem cells in the brain, especially those responsible for producing oligodendrocytes, contributes to chemobrain. In CIRM-funded work, Dr. Monje has identified small molecules that may help prevent or ameliorate the symptoms of chemobrain.
Is it possible to use a technique developed to fight one disease to also fight another? For instance, the bubble baby disease, which has cured (I think) more than 50 children, may also help fight sickle cell anemia? Don Reed.
Dr. Lisa Kadyk: Hi Don. Yes, the same general technique can often be applied to more than one disease, although it needs to be “customized” for each disease. In the example you cite, the technique is an “autologous gene-modified bone marrow transplant” – meaning the cells come from the patient themselves. This technique is relevant for single gene mutations that cause diseases of the blood (hematopoietic) system. For example, in the case of “bubble baby” diseases, a single mutation can cause failure of immune cell development, leaving the child unable to fight infections, hence the need to have them live in a sterile “bubble”. To cure that disease, blood stem cells, which normally reside in the bone marrow, are collected from the patient and then a normal version of the defective gene is introduced into the cells, where it is incorporated into the chromosomes. Then, the corrected stem cells are transplanted back into the patient’s body, where they can repopulate the blood system with cells expressing the normal copy of the gene, thus curing the disease.
A similar approach could be used to treat sickle cell disease, since it is also caused by a single gene mutation in a gene (beta hemoglobin) that is expressed in blood cells. The same technique would be used as I described for bubble baby disease but would differ in the gene that is introduced into the patient’s blood stem cells.
Is there any concern that CIRM’s lack of support in basic research will hamper the amount of new approaches that can reach clinical stages? Jason
Dr. Kelly Shepard: CIRM always has and continues to believe that basic research is vital to the field of regenerative medicine. Over the past 10 years CIRM has invested $904 million in “discovery stage/basic research”, and about $215 million in training grants that supported graduate students, post docs, clinical fellows, undergraduate, masters and high school students performing basic stem cell research. In the past couple of years, with only a limited amount of funds remaining, CIRM made a decision to invest most of the remaining funds into later stage projects, to support them through the difficult transition from bench to bedside. However, even now, CIRM continues to sponsor some basic research through its Bridges and SPARK Training Grant programs, where undergraduate, masters and even high school students are conducting stem cell research in world class stem cell laboratories, many of which are the same laboratories that were supported through CIRM basic research grants over the past 10 years. While basic stem cell research continues to receive a substantial level of support from the NIH ($1.8 billion in 2018, comprehensively on stem cell projects) and other funders, CIRM believes continued support for basic research, especially in key areas of stem cell research and vital opportunities, will always be important for discovering and developing new treatments.
What is the future of the use of crispr cas9 in clinical trials in california/globally. Art Venegas
Dr. Kelly Shepard: CRISPR/Cas9 is a powerful gene editing tool. In only a few years, CRISPR/Cas9 technology has taken the field by storm and there are already a few CRISPR/Cas9 based treatments being tested in clinical trials in the US. There are also several new treatments that are at the IND enabling stage of development, which is the final testing stage required by the FDA before a clinical trial can begin. Most of these clinical trials involving CRISPR go through an “ex vivo” approach, taking cells from the patient with a disease causing gene, correcting the gene in the laboratory using CRISPR, and reintroducing the cells carrying the corrected gene back into the patient for treatment. Sickle cell disease is a prime example of a therapy being developed using this strategy and CIRM funds two projects that are preparing for clinical trials with this approach. CRISPR is also being used to develop the next generation of cancer T-cell therapies (e.g. CAR-T), where T-cells – a vital part of our immune system – are modified to target and destroy cancer cell populations. Using CRISPR to edit cells directly in patients “in vivo” (inside the body) is far less common currently but is also being developed. It is important to note that any FDA sanctioned “in vivo” CRISPR clinical trial in people will only modify organ-specific cells where the benefits cannot be passed on to subsequent generations. There is a ban on funding for what are called germ line cells, where any changes could be passed down to future generations.
CIRM is currently supporting multiple CRISPR/Cas9 gene editing projects in California from the discovery or most basic stage of research, through the later stages before applying to test the technique in people in a clinical trial.
While the field is new – if early safety signals from the pioneering trials are good, we might expect a number of new CRISPR-based approaches to enter clinical testing over the next few years. The first of these will will likely be in the areas of bone marrow transplant to correct certain blood/immune or metabolic diseases, and cancer immunotherapies, as these types of approaches are the best studied and furthest along in the pipeline.
Explain the differences between gene therapy and stem cell therapy?Renee Konkol
Dr. Stephen Lin: Gene therapy is the direct modification of cells in a patient to treat a disease. Most gene therapies use modified, harmless viruses to deliver the gene into the patient. Gene therapy has recently seen many success in the clinic, with the first FDA approved therapy for a gene induced form of blindness in 2017 and other approvals for genetic forms of smooth muscle atrophy and amyloidosis.
Stem cell therapy is the introduction of stem cells into patients to treat a disease, usually with the purpose of replacing damaged or defective cells that contribute to the disease. Stem cell therapies can be derived from pluripotent cells that have the potential to turn into any cell in the body and are directed towards a specific organ lineage for the therapy. Stem cell therapies can also be derived from other cells, called progenitors, that have the ability to turn into a limited number of other cells in the body. for example hematopoietic or blood stem cells (HSCs), which are found in bone marrow, can turn into other cells of the blood system including B-cells and T-cells: while mesenchymal stem cells (MSCs), which are usually found in fat tissue, can turn into bone, cartilage, and fat cells. The source of these cells can be from the patient’s own body (autologous) or from another person (allogeneic).
Gene therapy is often used in combination with cell therapies when cells are taken from the patient and, in the lab, modified genetically to correct the mutation or to insert a correct form of the defective gene, before being returned to patients. Often referred to as “ex vivo gene therapy” – because the changes are made outside the patient’s body – these therapies include Chimeric Antigen Receptor T (CAR-T) cells for cancer therapy and gene modified HSCs to treat blood disorders such as severe combined immunodeficiency and sickle cell disease. This is an exciting area that has significantly improved and even cured many people already.
Currently, how can the outcome of CIRM stem cell medicine projects and clinical trials be soundly interpreted when their stem cell-specific doses are not known?James L. Sherley, M.D., Ph.D., Director. Asymmetrex, LLC
Dr. Stephen Lin: Stem cell therapies that receive approval to conduct clinical trials must submit a package of data to the FDA that includes studies that demonstrate their effectiveness, usually in animal models of the disease that the cell therapy is targeting. Those studies have data on the dose of the cell therapy that creates the therapeutic effect, which is used to estimate cell doses for the clinical trial. CIRM funds discovery and translational stage awards to conduct these types of studies to prepare cell therapies for clinical trials. The clinical trial is also often designed to test multiple doses of the cell therapy to determine the one that has the best therapeutic effect. Dosing can be very challenging with cell therapies because of issues including survival, engraftment, and immune rejection, but CIRM supports studies designed to provide data to give the best estimate possible.
Is there any research on using stem cells to increase the length of long bones in people?” For example, injecting stem cells into the growth plates to see if the cells can be used to lengthen limbs.Sajid
Dr. Kelly Shepard: There is quite a lot of ongoing research seeking ways to repair bones with stem cell based approaches, which is not the same but somewhat related. Much of this is geared towards repairing the types of bone injuries that do not heal well naturally on their own (large gaps, dead bone lesions, degenerative bone conditions). Also, a lot of this research involves engineering bone tissues in the lab and introducing the engineered tissue into a bone lesion that need be repaired. What occurs naturally at the growth plate is a complex interaction between many different cell types, much of which we do not fully understand. We do not fully understand how to use the cells that are used to engineer bone tissue in the lab. However, a group at Stanford, with some CIRM support, recently discovered a “skeletal stem cell” that exists naturally at the ends of human bones and at sites of fracture. These are quite different than MSCs and offer a new path to be explored for repairing and generating bone.
An independent Economic Impact Report says the California Institute for Regenerative Medicine (CIRM) has had a major impact on California’s economy, creating tens of thousands of new jobs, generating hundreds of millions of dollars in new taxes, and producing billions of dollars in additional revenue for the state.
The report, done by Dan Wei and Adam Rose at the Price School of Public Policy at the University of Southern California, looked at the impacts of CIRM funding on both the state and national economy from the start of the Stem Cell Agency in 2004 to the end of 2018.
The total impacts on the California economy are estimated
billion of additional gross output (sales revenue)
million of additional state/local tax revenues
million of additional federal tax revenues
additional full-time equivalent (FTE) jobs, half of which offer salaries
considerably higher than the state average
Millan, M.D., CIRM’s President and CEO, says the report reflects the Agency’s
role in building an ecosystem to accelerate the translation of important stem
cell science to solutions for patients with unmet medical needs. “CIRM’s
mission on behalf of patients has been the priority from day one, but this
report shows that CIRM funding brings additional benefits to the state. This report
reflects how CIRM is promoting economic growth in California by attracting
scientific talent and additional capital, and by creating an environment that
supports the development of businesses and commercial enterprises in the state”
In addition to the benefits to California, the impacts
outside of California on the US economy are estimated to be:
billion of additional gross output (sales revenue)
million of additional state (non-Californian) & local tax revenue
million of additional federal tax revenues
additional full-time equivalent (FTE) jobs
researchers summarize their findings, saying: “In terms of economic impacts, the
state’s investment in CIRM has paid handsome dividends in terms of output, employment,
and tax revenues for California.”
The estimates in the report are based on the economic stimulus
created by CIRM funding and by the co-funding that researchers and companies
were required to provide for clinical and late-stage preclinical projects. The
estimates also include:
Investments in CIRM-supported projects from private funders such
as equity investments, public offerings and mergers and acquisitions,
Follow-on funding from the National Institutes of Health and other
organizations due to data generated in CIRM-funded projects
Funding generated by clinical trials held at CIRM’s Alpha Stem
Cell Clinics network
researchers state “Nearly half of these impacts emanate from the $2.67 billion
CIRM grants themselves.”
economic impact of California’s investment in stem and regenerative cell
research is reflective of significant progress in this field that was just
being born at the time of CIRM’s creation,” says Dr. Millan. “We fund the most
promising projects based on rigorous science from basic research into clinical
trials. We partnered with researchers and companies to increase the likelihood
of success and created specialized infrastructure such as the Alpha Clinics
Network to support the highest quality of clinical care and research standards
for these novel approaches. The
ecosystem created by CIRM has attracted scientists, companies and capital from outside
the state to California. By supporting promising science projects early on,
long before most investors were ready to come aboard, we enabled our scientists
to make progress that positioned them to attract significant commercial
investments into their programs and into California.”
think one of the greatest strengths of CIRM has been their focus on development
of new stem cell therapies that can become real medicines,” says UCLA and
Orchard Therapeutics’ Don Kohn, M.D. “This has meant guiding academic
investigators to do the things that may be second nature in
industry/pharmaceutical companies but are not standard for basic or clinical
research. The support from CIRM to perform the studies and regulatory
activities needed to navigate therapies through the FDA and to form alliances
with biotech and pharma companies has allowed the stem cell gene therapy we
developed to treat SCID babies to be advanced and licensed to Orchard
Therapeutics who can make it available to patients across the country.”
support has been instrumental to our early successes and our ability to rapidly
progress Forty Seven’s CD47 antibody targeting approach with magrolimab,” says
Mark Chao, M.D., Ph.D., Founder and Vice President of Clinical Development at
Forty Seven Inc. “ CIRM was an early collaborator in our clinical
programs, and will continue to be a valued partner as we move forward with our
MDS/AML clinical trials.”
researchers say the money generated by partnerships and investments, what is
called “deal-flow funding”, is still growing and that the economic benefits
created by them are likely to continue for some time: “Deal-flow funding
usually involves several waves or rounds of capital infusion over many years,
and thus is it expected that CIRM’s past and current funding will attract
increasing amounts of industry investment and lead to additional spending
injections into the California economy in the years to come.”
They conclude their report by saying: “CIRM has led to
California stem cell research and development activities becoming a leader
among the states.”
