Charting a new course for stem cell research

What are the latest advances in stem cell research targeting cancer? Can stem cells help people battling COVID-19 or even help develop a vaccine to stop the virus? What are researchers and the scientific community doing to help address the unmet medical needs of underserved communities? Those are just a few of the topics being discussed at the Annual CIRM Alpha Stem Cell Clinic Network Symposium on Thursday, October 8th from 9am to 1.30pm PDT.

Like pretty nearly everything these days the symposium is going to be a virtual event, so you can watch it from the comfort of your own home on a phone or laptop. And it’s free.

The CIRM Alpha Clinics are a network of leading medical centers here in California. They specialize in delivering stem cell and gene therapies to patients. So, while many conferences look at the promise of stem cell therapies, here we deal with the reality; what’s in the clinic, what’s working, what do we need to do to help get these therapies to patients in need?

It’s a relatively short meeting, with short presentations, but that doesn’t mean it will be short on content. Some of the best stem cell researchers in the U.S. are taking part so you’ll learn an awful lot in a short time.

We’ll hear what’s being done to find therapies for

  • Rare diseases that affect children
  • Type 1 diabetes
  • HIV/AIDS
  • Glioblastoma
  • Multiple myeloma

We’ll discuss how to create a patient navigation system that can address social and economic determinants that impact patient participation? And we’ll look at ways that the Alpha Clinic Network can partner with community care givers around California to increase patient access to the latest therapies.

It’s going to be a fascinating day. And did I mention it’s free!

All you have to do is go to this Eventbrite page to register.

And feel free to share this with your family, friends or anyone you think might be interested.

We look forward to seeing you there.

Graphite Bio launches and will prepare for clinical trial based on CIRM-funded research

Josh Lehrer, M.D., CEO of Graphite Bio

This week saw the launch of the 45th startup company enabled by CIRM funding of translational research at California academic institutions. Graphite Bio officially launched with the help of $45M in funding led by bay area venture firms Versant Ventures and Samsara BioCapital to spinout a novel CRISPR gene editing platform from Stanford University to treat severe diseases. Graphite Bio’s lead candidate is for sickle cell disease and it harnesses CRISPR gene correction technology to correct the single DNA mutation in sickle cell disease and to restore normal hemoglobin expression in the red blood cells of sickle cell patients (Learn more about CRISPR from a previous blog post linked here).

Graphite Bio scientific founders

Matt Porteus, M.D., Ph.D and Maria Grazia Roncarolo, M.D., both from Stanford University, are the company’s scientific founders. Dr. Porteus, Dr. Roncarolo, and the Stanford team are currently supported by a CIRM  late stage preclinical grant  to complete the final preclinical studies and to file an Investigational New Drug application with the FDA, which will enable Graphite Bio to commence clinical studies of the CRISPR sickle cell disease gene therapy candidate in sickle cell patients in 2021.

Josh Lehrer, M.D., was appointed CEO of Graphite Bio and elaborated on the company’s gene editing approach in a news release.

“Our flexible, site-specific approach is extremely powerful and could be used to definitively correct the underlying causes of many severe genetic diseases, and also is applicable to broader disease areas. With backing from Versant and Samsara, we look forward to progressing our novel medicines into the clinic for patients with high unmet needs.”

In a press release, Dr. Porteus take a retrospective look on his preclinical research and its progress towards a clinical trial.

“It is gratifying to see our work on new gene editing approaches being translated into novel therapies. I’m very excited to be working with Versant again on a start-up and I look forward to collaborating with Samsara and the Graphite Bio team to bring a new generation of genetic treatments to patients.”

CIRM’s funding of late stage preclinical projects such this one is critical to its funding model, which de-risks the discovery, translational development and clinical proof of concept of innovative stem cell-based treatments until they can attract industry partnerships.

Building a progressive pipeline

Dr. Kelly Shepard

By Dr. Kelly Shepard

One of our favorite things to do at CIRM is deliver exciting news about CIRM projects. This usually entails discussion of recent discoveries that made headlines, or announcing the launch of a new CIRM-funded clinical trial …. tangible signs of progress towards addressing unmet medical needs through advances in stem technology.

But there are equally exciting signs of progress that are not always so obvious to the untrained eye-  those that we are privileged to witness behind the scenes at CIRM. These efforts don’t always lead to a splashy news article or even to a scientific publication, but they nonetheless drive the evolution of new ideas and can help steer the field away from futile lines of investigation. Dozens of such projects are navigating uncharted waters by filling knowledge gaps, breaking down technical barriers, and working closely with regulatory agencies to define novel and safe paths to the clinic.

These efforts can remain “hidden” because they are in the intermediate stages of the long, arduous and expensive journey from “bench to beside”.  For the pioneering projects that CIRM funds, this journey is unique and untrod, and can be fraught with false starts. But CIRM has developed tools to track the momentum of these programs and provide continuous support for those with the most promise. In so doing, we have watched projects evolve as they wend their way to the clinic. We wanted to share a few examples of how we do this with our readers, but first… a little background for our friends who are unfamiliar with the nuts and bolts of inventing new medicines.

A common metaphor for bringing scientific discoveries to market is a pipeline, which begins in a laboratory where a discovery occurs, and ends with government approval to commercialize a new medicine, after it is proven to be safe and effective. In between discovery and approval is a stage called “Translation”, where investigators develop ways to transition their “research level” processes to “clinically compatible” ones, which only utilize substances that are of certified quality for human use. 

Investigators must also work out novel ways to manufacture the product at larger scale and transition the methods used for testing in animal models to those that can be implemented in human subjects.

A key milestone in Translation is the “preIND” (pre Investigational New Drug (IND) meeting, where an investigator presents data and plans to the US Food and Drug Administration (FDA) for feedback before next stage of development begins, the pivotal testing needed to show it is both safe and effective.

These “IND enabling studies” are rigorous but necessary to support an application for an IND and the initiation of clinical trials, beginning with phase 1 to assess safety in a small number of individuals, and phase 2, where an expanded group is evaluated to see if the therapy has any benefits for the patient. Phase 3 trials are studies of very large numbers of individuals to gain definitive evidence of safety and therapeutic effect, generally the last step before applying to the FDA for market approval. An image of the pipeline and the stages described are provided in our diagram below.

The pipeline can be notoriously long and tricky, with plenty of twists, turns, and unexpected obstacles along the way. Many more projects enter than emerge from this gauntlet, but as we see from these examples of ‘works in progress”, there is a lot of momentum building.

Caption for Graphic: This graphic shows the number of CIRM-funded projects and the stages they have progressed through multiple rounds of CIRM funding. For example, the topmost arrow shows that are about 19 projects at the translational stage of the pipeline that received earlier support through one of CIRM’s Discovery stage programs. Many of these efforts came out of our pre-2016 funding initiatives such as Early Translation, Basic Biology and New Faculty Awards. In another example, you can see that about 15 awards that were first funded by CIRM at the IND enabling stage have since progressed into a phase 1 or phase 2 clinical trials. While most of these efforts also originated in some of CIRM’s pre-2016 initiatives such as the Disease Team Awards, others have already progressed from CIRM’s newer programs that were launched as part of the “2.0” overhaul in 2016 (CLIN1).

The number of CIRM projects that have evolved and made their way down the pipeline with CIRM support is impressive, but it is clearly an under-representation, as there are other projects that have progressed outside of CIRM’s purview, which can make things trickier to verify.

We also track projects that have spun off or been licensed to commercial organizations, another very exciting form of “progression”. Perhaps those will contribute to another blog for another day! In the meantime, here are a just a few examples of some of the progressors that are depicted on the graphic.

Meet the people who are changing the future

Kristin MacDonald

Every so often you hear a story and your first reaction is “oh, I have to share this with someone, anyone, everyone.” That’s what happened to me the other day.

I was talking with Kristin MacDonald, an amazing woman, a fierce patient advocate and someone who took part in a CIRM-funded clinical trial to treat retinitis pigmentosa (RP). The disease had destroyed Kristin’s vision and she was hoping the therapy, pioneered by jCyte, would help her. Kristin, being a bit of a pioneer herself, was the first person to test the therapy in the U.S.

Anyway, Kristin was doing a Zoom presentation and wanted to look her best so she asked a friend to come over and do her hair and makeup. The woman she asked, was Rosie Barrero, another patient in that RP clinical trial. Not so very long ago Rosie was legally blind. Now, here she was helping do her friend’s hair and makeup. And doing it beautifully too.

That’s when you know the treatment works. At least for Rosie.

There are many other stories to be heard – from patients and patient advocates, from researchers who develop therapies to the doctors who deliver them. – at our CIRM 2020 Grantee Meeting on next Monday September 14th Tuesday & September 15th.

It’s two full days of presentations and discussions on everything from heart disease and cancer, to COVID-19, Alzheimer’s, Parkinson’s and spina bifida. Here’s a link to the Eventbrite page where you can find out more about the event and also register to be part of it.

Like pretty much everything these days it’s a virtual event so you’ll be able to join in from the comfort of your kitchen, living room, even the backyard.

And it’s free!

You can join us for all two days or just one session on one day. The choice is yours. And feel free to tell your friends or anyone else you think might be interested.

We hope to see you there.

CIRM partners with UCLA scientists to take on COVID-19

Don’t you love it when someone does your job for you and does it so well you have no need to add anything to it! Doesn’t happen very often – sad to say – but this week our friends at UCLA wrote a great article describing the work they are doing to target COVID-19. Best of all, all the work described is funded by CIRM. So read, and enjoy.

Two scientists in a lab at the UCLA Broad Stem Cell Research Center

By Tiare Dunlap, UCLA

As the COVID-19 pandemic rages on, UCLA researchers are rising to the occasion by channeling their specialized expertise to seek new and creative ways to reduce the spread of the virus and save lives. Using years’ — or even decades’ — worth of knowledge they’ve acquired studying other diseases and biological processes, many of them have shifted their focus to the novel coronavirus, and they’re collaborating across disciplines as they work toward new diagnostic tests, treatments and vaccines.

At UCLA, more than 230 research projects, including several being led by members of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, are contributing to that mission.

“As a result of the pandemic, everyone on campus is committed to finding ways that their unique expertise can help out,” said Dr. Brigitte Gomperts, professor and vice chair of research in pediatric hematology-oncology and pulmonary medicine at the David Geffen School of Medicine at UCLA and a member of the UCLA Children’s Discovery and Innovation Institute. “So many of my colleagues have repurposed their labs to work on the virus. It’s very seldom that you have one thing that everybody’s working on, and it has been truly inspiring to see how everyone has come together to try and solve this.”

Here’s a look at five projects in which UCLA scientists are using stem cells — which can self-replicate and give rise to all cell types — to take on COVID-19.

Using lung organoids as models to test possible treatments 

Dr. Brigitte Gomperts

Gomperts has spent years perfecting methods for creating stem cell–derived three-dimensional lung organoids. Now, she’s using those organoids to study how SARS-CoV-2, the virus that causes COVID-19, affects lung tissue and to rapidly screen thousands of prospective treatments. Because the organoids are grown from human cells and reflect the cell types and architecture of the lungs, they can offer unprecedented insights into how the virus infects and damages the organ.  

Gomperts is collaborating with UCLA colleagues Vaithilingaraja Arumugaswami, a virologist, and Robert Damoiseaux, an expert in molecular screening. Their goal is to find an existing therapy that could be used to reduce the spread of infection and associated damage in the lungs.

“We’re starting with drugs that have already been tested in humans because our goal is to find a therapy that can treat patients with COVID-19 as soon as possible,” Gomperts said. Read more.

Repurposing a cancer therapy

In addition to collaborating with Gomperts, Arumugaswami and Damoiseaux identified the cancer drug Berzosertib as a possible treatment for COVID-19 after screening 430 drug candidates. The drug, which is currently being tested in clinical trials for cancer, works by blocking a DNA repair process that is exploited by solid cancers and the SARS-CoV-2 virus, and the UCLA scientists found that it is very effective at limiting viral replication and cell death. 

“Clinical trials have shown that Berzosertib blocks the DNA repair pathway in cancer cells, but has no effects on normal, healthy cells,” Arumugaswami said.

Now, Arumugaswami and Gustavo Garcia Jr., a staff research associate, are testing Berzosertib and additional drug combinations on lung organoids developed in Gomperts’ lab and stem cell–derived heart cells infected with SARS-CoV-2. They suspect that if the drug is administered soon after diagnosis, it could limit the spread of infection and prevent complications. Read more.

Studying the immune response to the virus

Dr. Gay Crooks

Dr. Gay Crooks, professor of pathology and laboratory medicine and of pediatrics at the Geffen School of Medicine, and co-director of the Broad Stem Cell Research Center; and Dr. Christopher Seet,  

assistant professor of hematology-oncology at the Geffen School of Medicine

Crooks and Seet are using stem cells to model how immune cells recognize and fight the virus in a lab dish. To do that, they’re infecting blood-forming stem cells — which can give rise to all blood and immune cells — from healthy donors with parts of the SARS-CoV-2 virus and then coaxing the stem cells to produce immune cells called dendritic cells. Dendritic cells devour viral proteins, chop them up into pieces and then present those pieces to other immune cells called T cells to provoke a response.

By studying that process, Crooks and Seet hope to identify which parts of the virus provoke the strongest T-cell responses. Developing an effective vaccine for SARS-CoV-2 will require a deep understanding of how the immune system responds to the virus, and this work could be an important step in that direction, giving researchers and clinicians a way to gauge the effectiveness of possible vaccines.

“When we started developing this project some years ago, we had no idea it would be so useful for studying a viral infection — any viral infection,” Crooks said. “It was only because we already had these tools in place that we could spring into action so fast.” Read more.

Developing a booster that could help a vaccine last longer

Song Li, chair and professor of bioengineering at the UCLA Samueli School of Engineering

A COVID-19 vaccine will need to provide long-term protection from infection. But how long a vaccine protects from infection isn’t solely dependent on the vaccine.

The human body relies on long-living immune cells called T memory stem cells that guard against pathogens such as viruses and bacteria that the body has encountered before. Unfortunately, the body’s capacity to form T memory stem cells decreases with age. So no matter how well designed a vaccine is, older adults who don’t have enough of a response from T memory stem cells will not be protected long-term.

To address that issue, Li is developing an injectable biomaterial vaccine booster that will stimulate the formation of T memory stem cells. The booster is made up of engineered materials that release chemical messengers to stimulate the production of T memory stem cells. When combined with an eventual SARS-CoV-2 vaccine, they would prompt the body to produce immune cells primed to recognize and eliminate the virus over the long term.

“I consider it my responsibility as a scientist and an engineer to translate scientific findings into applications to help people and the community,” Li said. Read more.

Creating an off-the-shelf cell therapy

Lili Yang, associate professor of microbiology, immunology and molecular genetics in the UCLA College

Invariant natural killer T cells, or iNKT cells, are the special forces of the immune system. They’re extremely powerful and can immediately recognize and respond to many different intruders, from infections to cancer.

Yang is testing whether iNKT cells would make a particularly effective treatment for COVID-19 because they have the capacity to kill virally infected cells, offer protection from reinfection and rein in the excessive inflammation caused by a hyperactive immune response to the virus, which is thought to be a major cause of tissue damage and death in people with the disease.

One catch, though, is that iNKT cells are incredibly scarce: One drop of human blood contains around 10 million blood cells but only around 10 iNKT cells. That’s where Yang’s research comes in. Over the past several years, she has developed a method for generating large numbers of iNKT cells from blood-forming stem cells. While that work was aimed at creating a treatment for cancer, Yang’s lab has adapted its work over the past few months to test how effective stem cell–derived iNKT cells could be in fighting COVID-19. With her colleagues, she has been studying how the cells work in fighting the disease in models of SARS-CoV-2 infection that are grown from human kidney and lung cells.

“My lab has been developing an iNKT cell therapy for cancer for years,” Yang said. “This means a big part of the work is already done. We are repurposing a potential therapy that is very far along in development to treat COVID-19.” Read more.

“Our center is proud to join CIRM in supporting these researchers as they adapt projects that have spent years in development to meet the urgent need for therapies and vaccines for COVID-19,” said Dr. Owen Witte, founding director of the UCLA Broad Stem Cell Research Center. “This moment highlights the importance of funding scientific research so that we may have the foundational knowledge to meet new challenges as they arise.” Crooks, Gomperts, Seet and Yang are all members of the UCLA Jonsson Comprehensive Cancer Center. Damoiseaux is a professor of molecular and medical pharmacology and director of the Molecular Shared Resource Center at the California NanoSystems Institute at UCLA

Driving Innovation While Addressing Health Disparities Among People of Color

One of the wonders of regenerative medicine is its broad applicability, which provides us with the opportunity to build upon existing knowledge and concepts.  In the midst of a global pandemic, researchers have responded to the needs of patients severely afflicted with COVID-19 by repurposing existing therapies being developed to treat patients.  The California Institute for Regenerative Medicine (CIRM) responded immediately to the pandemic and to researchers wanting to help by providing $5 million in emergency funding for COVID-19 related projects.  In a short time span, this funding has driven innovation in the form of 17 new projects targeting COVID-19, many of which are based on previously developed concepts being repurposed to deal with the novel coronavirus.

One such example is a clinical trial funded by CIRM that uses natural killer (NK) cells, a type of white blood cell that is a vital part of the immune system, which are administered to patients with COVID-19. NK cells play an important role in defense against cancer and in fighting off viral infections.  In fact, this exact same therapy was previously used in a clinical trial for patients with Acute Myeloid Leukemia, a type of blood cancer.

Another clinical trial funded by CIRM uses mesenchymal stromal cells (MSCs), a type of stem cell, to treat acute respiratory distress syndrome (ARDS), a life-threatening lung injury that occurs when fluid leaks into the lungs.  As a result of ARDS, oxygen cannot get into the body and patients have difficulty breathing.  ARDS is one of the most serious and lethal consequences of COVID-19, which is why this trial was expanded after the coronavirus pandemic to include COVID-19 positive patients.   

Despite these great strides in driving innovation of therapies, one challenge that still needs to be tackled is providing patients access to these therapies, particularly people from underrepresented and underserved communities.  In California alone, there have been over 621,000 positive cases as of August 2020, with more cases every day.  However, the impact of the pandemic is disproportionately affecting the Latinx and African American communities more than others. An analysis by the Los Angeles Times found that the Latinx and African American communities have double the mortality rate from the coronavirus in Los Angeles County.  Additionally, a surge in cases is being seen in poorer communities in comparison to wealthier ones.

Until a vaccine can be successfully developed and implemented to obtain herd immunity, the number of cases will continue to climb.  There is also the challenge of the long term health effects of COVID-19, which can consist of neurological, breathing, and heart problems according to an article in Science.  Unfortunately, a study published in the New England Journal of Medicine found that despite disproportionately higher rates of COVID-19 infection, hospitalization and death among people of color, they are significantly underrepresented in COVID-19 clinical trials.

The challenge of underrepresentation in clinical trials and research needs to be addressed by creating a more diverse population of study participants, so as to better generalize results to the U.S. population as a whole.  CIRM Board Member Ysabel Duron, a leading figure in cancer education in the Latinx community, has advocated for more inclusion and outreach efforts directed towards underserved and underrepresented communities.  By communicating with patients in underserved and underrepresented communities, building relationships established on a foundation of trust, and connecting patients with potential trial matches, underrepresentation can be alleviated.

To help in addressing these disparities, CIRM has taken action by changing the requirements for its discovery stage research projects, which promote promising new technologies that could be translated to enable broad use and improve patient care, and clinical trial stage projects.

For clinical trials, all proposals must include a written plan in the application for outreach and study participation by underserved and disproportionately affected populations. Priority will be given to projects with the highest quality plans in this regard. For discovery projects, all proposals must provide a statement describing how their overall study plan and design has considered the influence of race, ethnicity, sex and gender diversity.  Additionally, all proposals should discuss the limitations, advantages, and/or challenges in developing a product or tools that addresses the unmet medical needs of California’s diverse population, including underserved communities.  There is still much more work that needs to be done to address health disparities, but steps such as these can help steer progress in the right direction.

Driving innovation while addressing health disparities among people of color is just one of many opportunities and challenges of regenerative medicine in a post pandemic world.  This blog post is part of Signal’s fifth annual blog carnival.

Therapy developed with CIRM award used in new clinical trial for COVID-19

While doctors are still trying to better understand how to treat some of the most severe cases of COVID-19, researchers are looking at their current scientific “toolkit” to see if any potential therapies for other diseases could also help treat patients with COVID-19. One example of this is a treatment developed by Fate Therapeutics called FT516, which received support in its early stages from a Late Stage Preclinical grant awarded by CIRM.

FT516 uses induced pluripotent stem cells (iPSCs), which are a kind of stem cell made from reprogrammed skin or blood cells. These newly made stem cells have the potential to become any kind of cell in the body. For FT516, iPSCs are transformed into natural killer (NK) cells, which are a type of white blood cell that are a vital part of the immune system and play a role in fighting off viral infections.

Prior to the coronavirus pandemic, FT516 was used in a clinical trial to treat patients with acute myeloid leukemia (AML) and B-cell lymphoma, which are two different kinds of blood cancer.

Due to the natural ability of NK cells to fight off viruses, it is believed that FT516 may also help play a role in diminishing viral replication of the novel coronavirus in COVID-19 patients. In fact, Fate Therapeutics, in partnership with the University of Minnesota, has treated their first COVID-19 patient with FT516 in a new clinical trial.

In a news release, Dr. Joshua Rhein, Physician at the University of Minnesota running the trial site, elaborates on how FT516 could help COVID-19 patients.

“The medical research community has been mobilized to meet the unique challenges that COVID-19 presents. There are limited treatment options for COVID-19, and we have been inundated daily with reports of varying quality describing the potential of numerous therapies. We know that NK cells play an important role in responding to SARS-CoV-2, the virus responsible for COVID-19, and that these cells often become depleted in infected patients. Our intent is to replenish NK cells in order to restore a functional immune system and directly target the virus.”

In its own response to the coronavirus pandemic, CIRM has funded three clinical trials as part of $5 million in emergency funding for COVID-19 related projects. They include the following: a convalescent plasma study conducted by Dr. John Zaia at City of Hope, a treatment for acute respiratory distress syndrome (a serious and lethal consequence of COVID-19) conducted by Dr. Michael Matthay at UCSF, and a study that also uses NK cells to treat COVID-19 patients conducted by Dr. Xiaokui Zhang at Celularity Inc.  Visit our dashboard page to learn more about these clinical projects.

Perseverance: from theory to therapy. Our story over the last year – and a half

Some of the stars of our Annual Report

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.

Dr. Catriona Jamieson, UC San Diego physician and researcher

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.

Byron Jenkins, former Naval fighter pilot who battled back from his own fight with multiple myeloma

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.

Jordan Janz and Dr. Stephanie Cherqui

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.

Sneha Santosh, former CIRM Bridges student and now a researcher with Novo Nordisk

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 hope you enjoy it.

Celebrating a life that almost didn’t happen

Evie Vaccaro

You can’t look at this photo and not smile. This is Evie Vaccaro, and it’s clear she is just bursting with energy and vitality. Sometimes it feels like I have known Evie all her life. In a way I have. And I feel so fortunate to have done so, and that’s why this photo is so powerful, because it’s a life that almost ended before it had a chance to start.

Evie was born with a rare condition called Severe Combined Immunodeficiency (SCID). Children with this condition lack a functioning immune system so even a simple cold or diaper rash can prove fatal. Imagine how perilous their lives are in a time of COVID-19. These children used to be called “bubble babies” because they were often kept inside sterile plastic bubbles to keep them alive. Many died before their second birthday.

Today there is no need for plastic bubbles. Today, we have a cure. That’s a word we use very cautiously, but in Evie’s case, and the case of more than 40 other children, we use it with pride.

Dr. Don Kohn and a child born with SCID

Dr. Don Kohn at UCLA has developed a method of taking the child’s own blood stem cells and, in the lab, inserting a corrected copy of the gene that caused SCID, and then returning those cells to the child. Because they are stem cells they multiply and renew and replicate themselves, creating a new blood supply, one free of the SCID mutation. The immune system is restored. The children are cured.

This is a story we have told several times before, but we mention it again because, well, it never gets old, and because Evie is on the front and back cover of our upcoming Annual Report. The report is actually a look back on the last 18 months in CIRM’s life, reporting on the progress we have made in advancing stem cell research, in saving and changing lives, and in producing economic benefits for California (billions of dollars in sales revenue and taxes and thousands of jobs).  

Evie’s story, Evie’s photo, is a reminder of what is possible thanks to the voters of California who created CIRM back in 2004. Hers is just one of the stories in the report. I think,  you’ll enjoy reading all of them.

Of course, I might be just a little bit biased.
