Stories that Caught Our Eye: New ways to heal old bones; and keeping track of cells once they are inside you

How Youth Factor Can Help Repair Old Bones

As we get older things that used to heal quickly tend to take a little longer to get better. In some cases, a lot longer. Take bones for example. A fracture in someone who is in their 70’s often doesn’t heal as quickly, or completely, as in someone much younger. For years researchers have been working on ways to change that. Now we may be one step closer to doing just that.

We know that using blood stem cells can help speed up healing for bone fractures (CIRM is funding work on that) and now researchers at Duke Health believe they have figured out how that works.

The research, published in the journal Nature Communications, identifies what the Duke team call the “youth factor” inside bone marrow stem cells. It’s a type of white blood cell called a macrophage. They say the proteins these macrophages produce help stimulate bone repair.

In a news story in Medicine News Line  Benjamin Alman, senior author on the study, says:

“While macrophages are known to play a role in repair and regeneration, prior studies do not identify secreted factors responsible for the effect. Here we show that young macrophage cells play a role in the rejuvenation process, and injection of one of the factors produced by the young cells into a fracture in old mice rejuvenates the pace of repair. This suggests a new therapeutic approach to fracture rejuvenation.”

Next step, testing this in people.

A new way to track stem cells in the body

It’s one thing to transplant stem cells into a person’s body. It’s another to know that they are going to go where you want them to and do what you want them to. University of Washington researchers have invented a device that doesn’t just track where the cells end up, but also what happens to them along the way.

The device is called “CellTagging”, and in an article in Health Medicine Network, Samantha Morris, one of the lead researchers says this could help in better understanding how to use stem cells to grow replacement tissues and organs.

“There is a lot of interest in the potential of regenerative medicine — growing tissues and organs in labs — to test new drugs, for example, or for transplants one day. But we need to understand how the reprogramming process works. We want to know if the process for converting skin cells to heart cells is the same as for liver cells or brain cells. What are the special conditions necessary to turn one cell type into any other cell type? We designed this tool to help answer these questions.”

In the study, published in the journal Nature, the researchers explain how they use a virus to insert tiny DNA “barcodes” into cells and that as the cells travel through the body they are able to track them.

Morris says this could help scientists better understand the conditions needed to more effectively program cells to do what we want them to.

“Right now, cell reprogramming is really inefficient. When you take one cell population, such as skin cells, and turn it into a different cell population — say intestinal cells — only about 1 percent of cells successfully reprogram. And because it’s such a rare event, scientists have thought it is likely to be a random process — there is some correct set of steps that a few cells randomly hit upon. We found the exact opposite. Our technology lets us see that if a cell starts down the right path to reprogramming very early in the process, all of its related sibling cells and their descendants are on the same page, doing the same thing.”

New hope for stem cell therapy in patients with leukemia

LeukemiaWhiteBloodCell

Leukemia white blood cell

Of the many different kinds of cancer that affect humans, leukemia is the most common in young people. As with many types cancer, doctors mostly turn to chemotherapy to treat patients. Chemotherapy, however, comes with its own share of issues, primarily severe side effects and the constant threat of disease recurrence.

Stem cell therapy treatment has emerged as a potential cure for some types of cancer, with leukemia patients being among the first groups of patients to receive this type of treatment. While exciting because of the possibility of a complete cure, stem cell therapy comes with its own challenges. Let’s take a closer look.

Leukemia is characterized by abnormal white blood cells (also known as the many different types of cells that make up our immune system) that are produced at high levels. Stem cell therapy is such an appealing treatment option because it involves replacing the patient’s aberrant blood stem cells with healthy ones from a donor, which provides the possibility of complete and permanent remission for the patient.

Unfortunately, in approximately half of patients who receive this therapy, the donor cells (which turn into immune cells), can also destroy the patients healthy tissue (i.e. liver, skin etc…), because the transplanted blood stem cells recognize patient’s tissue as foreign. While doctors try to lessen this type of response (also known as graft versus host disease (GVHD)), by suppressing the patient’s immune system, this procedure lessens the effectiveness of the stem cell therapy itself.

Now scientists at the University of Zurich have made an important discovery – published in the journal Science Translational Medicine – that could mitigate this potentially fatal response in patients. They found that a molecule called GM-CSF, is a critical mediator of the severity of GVHD. Using a mouse model, they showed that if the donor cells were unable to produce GM-CSF, then mice fared significantly better both in terms of less damage to tissues normally affected by GVHD, such as the skin, and overall survival.

While exciting, the scientists were concerned about narrowing in on this molecule as a potential target to lessen GVHD, because GM-CSF, an important molecule in the immune system, might also be important for ensuring that the donor immune cells do their jobs properly. Reassuringly, the researchers found that blocking GM-CSF’s function had no effect on the ability of the donor cells to exert their anti-cancer effect. This was surprising because previously the ability of donor cells to cause GVHD, versus protect patients from the development of cancer was thought to occur via the same biological mechanisms.

Most excitingly, however, was that finding that high levels of GM-CSF are also observed in patient samples, and that the levels of GM-CSF correlate to the severity of GVHD. Dr. Burkhard Becher and his colleagues, the authors of this study, now want to run a clinical trial to determine whether blocking GM-CSF blocks GVHD in humans like it does in mice. In a press release, Dr. Becher states the importance of these findings:

“If we can stop the graft-versus-host response while preserving the anti-cancer effect, this procedure can be employed much more successfully and with fewer risks to the patient. This therapeutic strategy holds particular promise for patients with the poorest prognosis and highest risk of fatality.”

Promising Approach to Curing Spina Bifida Gets $5.6 Million from Stem Cell Agency

300px-Spina-bifida

Every day in the U.S. four children are born with spina bifida. It is the most common cause of lifelong paralysis and also frequently leads to other serious health problems affecting the bowel and bladder. The impact on families is enormous. A new approach to repairing the defect that causes spina bifida was today awarded $5.66 million by the Board of the California Institute for Regenerative Medicine (CIRM).

In spina bifida the spinal cord doesn’t form properly, in many cases leaving a section of it open, exposing tissues and nerves. The current standard of care is surgery, but even this leaves almost 60% of children unable to walk independently. Diana Farmer MD, and Aijun Wang PhD at U.C. Davis will use mesenchymal stem cells, taken from a donor placenta, and place them on a form of synthetic scaffold over the injury site in the womb. Tests in animals show this approach was able to repair the defect and prevent paralysis.

“Spina bifida is a devastating condition for babies born with this disorder and the families who care for them,” says Maria T. Millan, MD, President & CEO of CIRM. “CIRM has funded this important work from its earliest stages and we are committed to working with Dr. Farmer’s team to moving this work to the stage where it can be tested in patients.”

The CLIN1 award will provide funding to enable the UC Davis team to do the final testing and preparations needed to apply to the FDA for permission to start a clinical trial.

Dr. Farmer says she and Dr. Wang, have been working on this approach for more than ten years and are excited about being able to take the next step.

“There were many times of frustration, many times when cell types we explored and worked with didn’t work,” says Dr. Farmer. “But it’s the patients, seeing them, talking to them and working with them, that keeps me motivated to do the science, to keep persevering.”

If this therapy is successful it will have a huge economic impact on California, and on the rest of the world. Because spina bifida is a lifelong condition involving many operations, many stays in the hospital and, in some cases, lifelong use of a wheelchair this has a huge financial, and psychological, burden on the family.

“It affects them in so many ways; parents having to miss work or take time off work to care for their child, other children in the family feeling neglected because their brother or sister needs so much attention,” says Dr. Farmer. “That’s why we are so grateful to CIRM. Because this is a rare disease and finding funding for those is hard. CIRM has been a perfect partner in helping bring this approach, blending stem cell therapy and tissue engineering, together to help these families.”

Stories that caught our eye: Is a Texas law opening up access to stem cell treatments working? Another CIRM-funded company gets good news from the FDA.

TexasCapitol_shutterstock_494317324

In 2017 Texas passed a sweeping new law, HB 810, which allowed medical clinics to provide “investigational stem cell treatments to patients with certain severe chronic diseases or terminal illnesses.” Those in favor of the law argued that patients battling life-threatening or life-changing diseases should have the right to try stem cell therapies that were involved in a clinical trial.

Now a new study, published in the journal Stem Cells and Development, looks at the impact of the law. The report says that despite some recent amendments t there are still some concerns about the law including:

  • It allows treatment only if the patient has a “severe, chronic” illness but doesn’t define what that means
  • It doesn’t have clearly defined procedures on tracking and reporting procedures so it’s hard to know how many patients might be treated and what the outcomes are
  • There is no Food and Drug Administration (FDA) oversight of the patients being treated
  • Because the treatments are unproven there are fears this will “open up the state to unsavory and predatory practices by individuals preying on vulnerable patients”

The researchers conclude:

“While HB 810 opens up access to patients, it also increases significant risks for their safety and financial cost for something that might have no positive impact on their disease. Truly understanding the impact of stem cell based interventions (SCBI) requires scientific rigor, and accurate outcome data reporting must be pursued to ensure the safety and efficacy behind such procedures. This information must be readily available so that patients can make informed decisions before electing to pursue such treatments. The creation of the SCBI registry could allow for some level of scientific rigor, provide a centralized data source, and offer the potential for better informed patient choices, and might be the best option for the state to help protect patients.”

Another CIRM-funded company gets RMAT designation

Poseida

When Congress approved the 21st Century Cures Act a few years ago one of the new programs it created was the Regenerative Medicine Advanced Therapy (RMAT) designation. This was given to therapies that are designed to treat a serious or life-threatening condition, where early clinical stage trials show the approach is safe and appears to be effective.

Getting an RMAT designation is a big deal. It means the company or researchers are able to apply for an expedited review by the FDA and could get approval for wider use.

This week Poseida Therapeutics was granted RMAT designation by the Food and drug Administration (FDA) for P-BCMA-101, its CAR-T therapy for relapsed/refractory multiple myeloma. This is currently in a Phase 1 clinical trial that CIRM is funding

In this trial Poseida’s technology takes an immunotherapy approach that uses the patient’s own engineered immune system T cells to seek and destroy cancerous myeloma cells.

In a news release Eric Ostertag, Poseida’s CEO, welcomed the news:

“Initial Phase 1 data presented at the CAR-TCR Summit earlier this year included encouraging response rates and safety data, including meaningful responses in a heavily pretreated population. We expect to have an additional data update by the end of the year and look forward to working closely with the FDA to expedite development of P-BCMA-101.”

This means that five CIRM-funded companies have now been granted RMAT designations:

Stories that caught our eye: SanBio’s Traumatic Brain Injury trial hits its target; A new approach to endometriosis; and a SCID kid celebrates Halloween in style

TBI

Hopeful signs for treating brain injuries

There are more than 200,000 cases of traumatic brain injury (TBI) in the US every year. The injuries can be devastating, resulting in everything from difficult sleeping to memory loss, depression and severe disability. There is no cure. But this week the SanBio Group had some encouraging news from its Phase 2 STEMTRA clinical trial.

In the trial patients with TBI were given stem cells, derived from the bone marrow of healthy adult donors. When transplanted into the area of injury in the brain, these cells appear to promote recovery by stimulating the brain’s own regenerative ability.

In this trial the cells demonstrated what the company describes as “a statistically significant improvement in their motor function compared to the control group.”

CIRM did not fund this research but we are partnering with SanBio on another clinical trial targeting stroke.

 

Using a woman’s own cells to heal endometriosis

Endometriosis is an often painful condition that is caused when the cells that normally line the inside of the uterus grow outside of it, causing scarring and damaging other tissues. Over time it can result in severe pain, infertility and increase a woman’s risk for ovarian cancer.

There is no effective long-term treatment but now researchers at Northwestern Medicine have developed an approach, using the woman’s own cells, that could help treat the problem.

The researchers took cells from women, turned them into iPS pluripotent stem cells and then converted those into healthy uterine cells. In laboratory tests these cells responded to the progesterone, the hormone that plays a critical role in the uterus.

In a news release, Dr. Serdar Bulun, a senior author of the study, says this opens the way to testing these cells in women:

“This is huge. We’ve opened the door to treating endometriosis. These women with endometriosis start suffering from the disease at a very early age, so we end up seeing young high school girls getting addicted to opioids, which totally destroys their academic potential and social lives.”

The study is published in the journal Stem Cell Reports.

Happy Halloween from a scary SCID kid

A lot of the research we write about on the Stem Cellar focuses on potential treatments or new approaches that show promise. So every once in a while, it’s good to remind ourselves that there are already stem cell treatments that are not just showing promise, they are saving lives.

That is the case with Ja’Ceon Golden. Regular readers of our blog know that Ja’Ceon was diagnosed with Severe Combined Immunodeficiency (SCID) also known as “bubble baby disease” when he was just a few months old. Children born with SCID often die in the first few years of life because they don’t have a functioning immune system and so even a simple infection can prove life-threatening.

Fortunately Ja’Ceon was enrolled in a CIRM-funded clinical trial at UC San Francisco where his own blood stem cells were genetically modified to correct the problem.

IMG_20181030_123500

Today he is a healthy, happy, thriving young boy. These pictures, taken by his great aunt Dannie Hawkins, including one of him in his Halloween costume, show how quickly he is growing. And all thanks to some amazing researchers, an aunt who wouldn’t give up on him, and the support of CIRM.

Living with sickle cell disease: one person’s story of pain and prejudice and their hopes for a stem cell therapy

Whenever we hold an in-person Board meeting at CIRM we like to bring along a patient or patient advocate to address the Board. Hearing from the people they are trying to help, who are benefiting or may benefit from a therapy CIRM is funding, reminds them of the real-world implications of the decisions they make and the impact they have on people’s lives.

At our most recent meeting Marissa Coors told her story.

Marissa at ICOC side view copy

Marissa Coors addressing the CIRM Board

My name is Marissa Coors, I have sickle cell disease. I was diagnosed with sickle cell disease at six months of age. I am now 40. Sickle cell has been a part of my life every day of my life.

The treatments you are supporting and funding here at CIRM are very important. They offer a potential cure to a disease that desperately needs one. I want to tell you just how urgently people with sickle cell need a cure.

I have been hospitalized so many times that my medical record is now more than 8 gigabytes. I have almost 900 pages in my medical record from my personal doctor alone.

I live with pain every day of my life but because you can’t see pain most people have no idea how bad it can be. The pain comes in two forms:

Chronic pain – this comes from the damage that sickle cell disease does to the body over many years. My right knee, my left clavicle, my lower back are all damaged because of the disease. I get chronic headaches. All these are the result of a lifetime of crisis.

Acute pain – this is the actual crisis that can’t be controlled, where the pain is so intense and the risk of damage to my organs so great that it requires hospitalization. That hospitalization can result in yet more pain, not physical but emotional and psychological pain.

But those are just the simple facts. So, let me tell you what it’s really like to live with sickle cell disease.

Marissa at ICOC front, smiling

It means being in a constant state of limbo and a constant state of unknown because you have no idea when the next crisis is going to come and take over and you have to stop your life. You have absolutely no idea how bad the pain will be or how long it will last.

It is a constant state of frustration and upset and even a constant state of guilt because it is your responsibility to put in place all the safety nets and plans order to keep life moving as normally as possible, not just for you but for everyone else around you. And you know that when a crisis comes, and those plans get ripped up that it’s not just your own life that gets put on hold while you try to deal with the pain, it’s the lives of those you love.

It means having to put your life on hold so often that it’s hard to have a job, hard to have a career or lead a normal life. Hard to do the things everyone else takes for granted. For example, in my 30’s, while all my friends from home and college were building careers and getting married and having families, I was in a cancer ward trying to stay alive, because that’s where they put you when you have sickle cell disease. The cancer ward.

People talk about new medications now that are more effective at keeping the disease under control. But let me tell you. As a black woman walking into a hospital Emergency Room saying I am having a sickle cell crisis and need pain medications, and then naming the ones I need, too often I don’t get treated as a patient, I get treated as a drug addict, a drug seeker.

Even when the doctors do agree to give me the medications I need they often act in a way that clearly shows they don’t believe me. They ask, “How do we know this is a crisis, why is it taking you so long for the medication to take effect?” These are people who spent a few days in medical school reading from a textbook about sickle cell disease. I have spent a lifetime living with it and apparently that’s still not enough for them to trust that I do know what I am talking about.

That’s when I usually say, “Goodbye and don’t forget to send in your replacement doctor because I can’t work with you.”

I have had doctors take away my medication because they wanted to see how I would react without it.

If I dare to question what a doctor or nurse does, they frequently tell me they have to go and take care of other patients who are really sick, not like me.

Even when I talk in my “nice white lady” voice they still treat me and call me “an angry black girl”. Girl. I’m a 40 year old woman but I get treated like a child.

It’s hard to be in the hospital surrounded by doctors and nurses and yet feel abandoned by the medical staff around you.

This month alone 25 people have died from sickle cell in the US. It’s not because we don’t have treatments that can help. It’s due to negligence, not getting the right care at the right time.

I know the work you do here at CIRM won’t change those attitudes. But maybe the research you support could find a cure for sickle cell, so people like me don’t have to endure the pain, the physical, emotional and spiritual pain, that the disease brings every day.

You can read about the work CIRM is funding targeting sickle cell disease, including two clinical trials, on this page on our website.

Mechanical forces are the key to speedy recovery after blood cancer treatment

MIT-Stem-Cell-Mechanics_0

Blood cancers, such as leukemia and lymphoma, are projected to be responsible for 10% of all new cancer diagnoses this year. These types of cancers are often treated by killing the patient’s bone marrow (the site of blood cell manufacturing), with a treatment called irradiation. While effective for ridding the body of cancerous cells, this treatment also kills healthy blood cells. Therefore, for a time after the treatment, patients are particularly vulnerable to infections, because the cellular components of the immune system are down for the count.

Now scientists at MIT have devised a method to make blood cells regenerate faster and  minimize the window for opportunistic infections.

Using multipotent stem cells (stem cells that are able to become multiple cell types) grown on a new and specialized surface that mimics bone marrow, the investigators changed the stem cells into different types of blood cells. When transplanted into mice that had undergone irradiation, they found that the mice recovered much more quickly compared to mice given stem cells grown on a more traditional plastic surface that does not resemble bone marrow as well.

This finding, published in the journal Stem Cell Research and Therapy, is particularly revolutionary, because it is the first time researchers have observed that mechanical properties can affect how the cells differentiate and behave.

The lead author of the study attributes the decreased recovery time to the type of stem cell that was given to mice compared to what humans are normally given after irradiation. Humans are given a stem cell that is only able to become different types of blood cells. The mice in this study, however, were give a stem cell that can become many different types of cells such as muscle, bone and cartilage, suggesting that these cells somehow changed the bone marrow environment to promote a more efficient recovery. They attributed a large part of this phenomenon to a secreted protein call ostepontin, which has previously been describe in activating the cells of the immune system.

In a press release, Dr. Viola Vogel, a scientist not related to study, puts the significance of these findings in a larger context:

“Illustrating how mechanopriming of mesenchymal stem cells can be exploited to improve on hematopoietic recovery is of huge medical significance. It also sheds light onto how to utilize their approach to perhaps take advantage of other cell subpopulations for therapeutic applications in the future.”

Dr. Krystyn Van Vliet, explains the potential to expand these findings beyond the scope of just blood cancer treatment:

“You could imagine that by changing their culture environment, including their mechanical environment, MSCs could be used for administration to target several other diseases such as Parkinson’s disease, rheumatoid arthritis, and others.”

 

How stem cells may help children battling birth injuries

From time to time we invite patients or patient advocates to post a guest blog on the Stem Cellar. Today we are featuring Brigitta Burguess, a mother and writer from Michigan, who focuses on pregnancy, parenting, and children with disabilities. Brigitta writes for the HIE Help Center, a website that offers information and supportive resources for families of children with disabilities.

HIE-Early-Intervention

Because stem cells are the building blocks of the immune system, they possess the ability to develop into other types of cells. You can use stem cells to help repair tissues, organs, and blood vessels, and even treat a host of different diseases. This is done through stem cell harvesting and stem cell therapy. In stem cell therapy, stem cells are injected into injured tissues in the hopes of replacing damaged tissue and preserving existing tissues.

Cord Blood

Every part of the human body contains stem cells. However, many areas of the body do not contain enough stem cells to make harvesting them worthwhile. Cord blood, the leftover blood collected from a baby’s umbilical cord or a mother’s placenta after birth, is especially beneficial because:

  • It provides a rich source of stem cells that can be changed into other types of cells and help to maintain and repair tissues
  • Its stem cells are immature and have not developed the ability to attack foreign cells, which makes them perfect for transplant
  • Its stem cells differ from embryonic stem cells in that they are considered adult stem cells and do not require the destruction of an embryo to harvest
  • It can be used to treat blood disorders, immune deficiencies, and certain cancers
  • Storing cord blood can help family and community members receive gene therapy treatment for the aforementioned conditions and diseases

The Applications of Stem Cell Therapy for Kids

Today, over 2,000 total cord blood stem cell transplants are performed annually, with the total number of cord blood banks worldwide reaching over 150. The innovations in stem cell therapy have made waves over the past four decades. Today, more than 80 difference diseases are being treated with cord blood stem cells.

In 2012, many clinical trials revealed that cord blood transplants were an effective treatment for cerebral palsy. Researchers also believe that cord blood stem cells have great potential in treating the neonatal brain injuries such as hypoxic-ischemic encephalopathy (HIE). As of right now, there is no indication that stem cell therapy can cure these conditions, but there is some evidence that it can lessen the severity of symptoms.

It is important to note that there is thus far no cure for hypoxic-ischemic encephalopathy (HIE) and resulting motor, cognitive, and/or intellectual disorders. Stem cell therapy seeks to limit the damage caused by HIE and reduce the severity of disabilities caused by HIE, but it is not a cure.

Because stem cell therapy is still in clinical trials, parents should think twice before going down this untested path, as no formal guidelines about administration protocol, dosages, safety, or treatment timeline have yet been established. Clinical trials are important for ensuring that treatments are safe and effective – unregulated treatments bear significant risk.

Stem Cell Agency Invests in New Immunotherapy Approach to HIV, Plus Promising Projects Targeting Blindness and Leukemia

HIV AIDS

While we have made great progress in developing therapies that control the AIDS virus, HIV/AIDS remains a chronic condition and HIV medicines themselves can give rise to a new set of medical issues. That’s why the Board of the California Institute for Regenerative Medicine (CIRM) has awarded $3.8 million to a team from City of Hope to develop an HIV immunotherapy.

The City of Hope team, led by Xiuli Wang, is developing a chimeric antigen receptor T cell or CAR-T that will enable them to target and kill HIV Infection. These CAR-T cells are designed to respond to a vaccine to expand on demand to battle residual HIV as required.

Jeff Sheehy

CIRM Board member Jeff Sheehy

Jeff Sheehy, a CIRM Board member and patient advocate for HIV/AIDS, says there is a real need for a new approach.

“With 37 million people worldwide living with HIV, including one million Americans, a single treatment that cures is desperately needed.  An exciting feature of this approach is the way it is combined with the cytomegalovirus (CMV) vaccine. Making CAR T therapies safer and more efficient would not only help produce a new HIV treatment but would help with CAR T cancer therapies and could facilitate CAR T therapies for other diseases.”

This is a late stage pre-clinical program with a goal of developing the cell therapy and getting the data needed to apply to the Food and Drug Administration (FDA) for permission to start a clinical trial.

The Board also approved three projects under its Translation Research Program, this is promising research that is building on basic scientific studies to hopefully create new therapies.

  • $5.068 million to University of California at Los Angeles’ Steven Schwartz to use a patient’s own adult cells to develop a treatment for diseases of the retina that can lead to blindness
  • $4.17 million to Karin Gaensler at the University of California at San Francisco to use a leukemia patient’s own cells to develop a vaccine that will stimulate their immune system to attack and destroy leukemia stem cells
  • Almost $4.24 million to Stanford’s Ted Leng to develop an off-the-shelf treatment for age-related macular degeneration (AMD), the leading cause of vision loss in the elderly.

The Board also approved funding for seven projects in the Discovery Quest Program. The Quest program promotes the discovery of promising new stem cell-based technologies that will be ready to move to the next level, the translational category, within two years, with an ultimate goal of improving patient care.

Congresswoman Barbara Lee (D-CA 13th District)

“I am deeply grateful for organizations like CIRM and NHLBI that do vital work every day to help people struggling with Sickle Cell Disease,” said Congresswoman Barbara Lee (D-CA 13th District). “As a member of the House Appropriations Subcommittee on Labor, Health and Human Services, and Education, I know well the importance of this work. This innovative partnership between CIRM and NHLBI is an encouraging sign of progress, and I applaud both organizations for their tireless work to cure Sickle Cell Disease.”

Under the agreement CIRM and the NHLBI will coordinate efforts to identify and co-fund promising therapies targeting SCD.  Programs that are ready to start an IND-enabling or clinical trial project for sickle cell can apply to CIRM for funding from both agencies. CIRM will share application information with the NHLBI and CIRM’s Grants Working Group (GWG) – an independent panel of experts which reviews the scientific merits of applications – will review the applications and make recommendations. The NHLBI will then quickly decide if it wants to partner with CIRM on co-funding the project and if the CIRM governing Board approves the project for funding, the two organizations will agree on a cost-sharing partnership for the clinical trial. CIRM will then set the milestones and manage the single CIRM award and all monitoring of the project.

“This is an extraordinary opportunity to create a first-of-its-kind partnership with the NHLBI to accelerate the development of curative cell and gene treatments for patients suffering with Sickle Cell Disease” says Maria T. Millan, MD, President & CEO of CIRM. “This allows us to multiply the impact each dollar has to find relief for children and adults who battle with this life-threatening, disabling condition that results in a dramatically shortened lifespan.  We are pleased to be able to leverage CIRM’s acceleration model, expertise and infrastructure to partner with the NHLBI to find a cure for this condition that afflicts 100,000 Americans and millions around the globe.”

California’s Stem Cell Agency Accelerates Treatments to Patients

The following article is an Op Ed that appeared in today’s print version of the San Francisco Chronicle

SanFranChronicle_Web

Biotechnology was born in California in the 1970s based on the discovery out of one of its universities and California is responsible for an industry that has impacted the lives of billions of people worldwide. In 2004, the voters of California approved Proposition 71, creating the California Institute for Regenerative Medicine and setting the state on the path to becoming a global leader in stem cell research. Today the therapies resulting from the institute’s work are not just changing lives, they are already saving lives.

Lives like Evie Vaccaro, who is alive today because of a treatment CIRM is funding. Vaccaro was born with SCID, also known as “bubble baby disease,” an immune disorder that often kills babies in their first two years. Vaccaro and dozens of other babies were given stem cell treatments thanks to the institute. All are showing improvement; some are now several years past treatment and considered cured.

An accident left Jake Javier from Danville paralyzed from the chest down on the eve of his high school graduation. Javier was treated in a CIRM-funded clinical trial. Today he has regained the use of his arms and hands, is driving a car and is a sophomore at Cal Poly San Luis Obispo. Five other patients treated at the same time as Javier have all experienced improvements meaning that instead of needing round-the-clock care, they can lead independent lives.

A study by the Tufts Center for the Study of Drug Development estimated it takes at least 10 years and $2.6 billion to develop one successful drug. In 14 years, and with just $3 billion, CIRM has funded 1,000 different projects, enrolled 900 patients, and supported 49 different clinical trials targeting diseases such as cancer, kidney failure and leukemia. Four of these programs have received an expedited designation by the U.S. Food and Drug Administration, meaning they could get faster approval to help more patients

We have created a network of world class medical clinics that have expertise in delivering treatments to patients. The CIRM Alpha Clinics offer treatments based on solid science, unlike the unlicensed clinics sprouting up around California that peddle unproven and potentially harmful therapies that cost patients thousands of dollars.

CIRM has:

  • Supported the creation of 12 stem-cell research facilities in California
  • Attracted hundreds of top-tier researchers to California
  • Trained a new generation of stem-cell scientists
  • Brought clinical trials to California — for example, one targeting ALS or Lou Gehrig’s disease
  • Deployed rigorous scientific standards and support so our programs have a “seal of approval” to attract $2.7 billion in additional investments from industry and other sources.

We recently have partnered with the National Institutes of Health to break down barriers and speed up the approval process to bring curative treatments to patients with Sickle Cell Disease.

Have we achieved all we wanted to? Of course not. The first decade of CIRM’s life was laying the groundwork, developing the knowledge and expertise and refining processes so that we can truly accelerate progress. As a leader in this burgeoning field of regenerative medicine, CIRM needs to continue its mission of accelerating stem-cell treatments to patients with unmet medical needs.
