CIRM public events highlight uncertain future of stem cell research

When governments cut funding for scientific research the consequences can be swift, and painful. In Canada last week for example, the government of Ontario cut $5 million in annual funding for stem cell research, effectively ending a project developing a therapy to heal the damaged lungs of premature babies.

Here in the US the federal government is already placing restrictions on support for fetal tissue research and there is speculation embryonic stem cell research could be next. That’s why agencies like CIRM are so important. We don’t rely on a government giving us money every year. Instead, thanks to the voters of California, we have had a steady supply of funds to enable us to plan long-term and support multi-year projects.

But those funds are due to run out soon. We anticipate funding our last new awards this year and while we have enough money to continue supporting all the projects our Board has already approved, we won’t be able to take on any new projects. That’s bad news for the scientists and, ultimately, really bad for the patients who are in need of new treatments for currently incurable diseases.

We are going to talk about that in two upcoming events.

UC San Diego Sanford Stem Cell Clinical Center

The first is a patient advocate event at UC San Diego on Tuesday, May 28th from 12.30pm to 1.30pm. It’s free, there is parking and snacks and refreshments will be available.

This will feature UC San Diego’s Dr. Catriona Jamieson, CIRM’s President and CEO Dr. Maria Millan and CIRM Board member and Patient Advocate for Parkinson’s Disease, David Higgins PhD. The three will talk about the exciting progress being made at UC San Diego and other programs around California, but also the uncertain future and the impact that could have for the field as a whole.

Here’s a link to an Eventbrite page that has more information about the event and also a link to allow you to RSVP ahead of time.

For all of you who don’t live in the San Diego Area – or who do but can’t make it to the event – we are holding a similar discussion online on a special Facebook Live: Ask the Stem Cell Team About the Future of Stem Cell Research event on Thursday, May 30th from noon till 1pm PDT.

This also features Dr. Millan and Dr. Higgins, but it also features UC Davis stem cell scientist, CIRM-grantee and renowned blogger Paul Knoepfler PhD.

Each brings their own experience, expertise and perspective on the field and will discuss the impact that a reduction in funding for stem cell research would have, not just in the short term but in the long run.

Because we all have a stake in what happens, both events – whether it’s in person or online – include time for questions from you, the audience.

You can find our Facebook Live: Ask the Stem Cell Team About the Future of Stem Cell Research on our Facebook page at noon on May 30th PDT

Stories that caught our eye: FDA grants orphan drug status to CIRM-funded therapy; stunning discovery upends ideas of cell formation; and how tadpoles grow new tails

Gut busting discovery

It’s not often you read the word “sensational” in a news release about stem cells. But this week researchers at the University of Copenhagen released findings that are overturning long-held ideas about the development of cells in our stomachs. So perhaps calling it “sensational” is not too big a stretch.

In the past it was believed that the development of immature cells in our stomachs, before a baby is born, was predetermined, that the cells had some kind of innate sense of what they were going to become and when. Turns out that’s not the case. The researchers say it’s the cells’ environment that determines what they will become and that all cells in the fetus’ gut have the potential to turn into stem cells.

In the “sensational” news release lead author, Kim Jensen, says this finding could help in the development of new therapies.

“We used to believe that a cell’s potential for becoming a stem cell was predetermined, but our new results show that all immature cells have the same probability for becoming stem cells in the fully developed organ. In principle, it is simply a matter of being in the right place at the right time. Here signals from the cells’ surroundings determine their fate. If we are able to identify the signals that are necessary for the immature cell to develop into a stem cell, it will be easier for us to manipulate cells in the wanted direction’.

The study is published in the journal Nature.                             

A tale of a tail

It’s long been known that some lizards and other mammals can regrow severed limbs, but it hasn’t been clear how. Now scientists at the University of Cambridge in the UK have figured out what’s going on.

Using single-cell genomics the scientists were able to track which genes are turned on and off at particular times, allowing them to watch what happens inside the tail of the African clawed frog tadpole as it regenerates the damaged limb.

They found that the response was orchestrated by a group of skin cells they called Regeneration-Organizing Cells, or ROCs. Can Aztekin, one of the lead authors of the study in the journal Science, says seeing how ROCs work could lead to new ideas on how to stimulate similar regeneration in other mammals.

“It’s an astonishing process to watch unfold. After tail amputation, ROCs migrate from the body to the wound and secrete a cocktail of growth factors that coordinate the response of tissue precursor cells. These cells then work together to regenerate a tail of the right size, pattern and cell composition.”

Orphan Drug Designation for CIRM-funded therapy

Poseida Therapeutics got some good news recently about their CIRM-funded therapy for multiple myeloma. The US Food and Drug Administration (FDA) granted them orphan drug designation.

Orphan drug designation is given to therapies targeting rare diseases or disorders that affect fewer than 200,000 people in the U.S. It means the company may be eligible for grant funding toward clinical trial costs, tax advantages, FDA user-fee benefits and seven years of market exclusivity in the United States following marketing approval by the FDA.

CIRM’s President and CEO, Dr. Maria Millan, says the company is using a gene-modified cell therapy approach to help people who are not responding to traditional approaches.

“Poseida’s technology is seeking to destroy these cancerous myeloma cells with an immunotherapy approach that uses the patient’s own engineered immune system T cells to seek and destroy the myeloma cells.”

Poseida’s CEO, Eric Ostertag, said the designation is an important milestone for the company therapy which “has demonstrated outstanding potency, with strikingly low rates of toxicity in our phase 1 clinical trial. In fact, the FDA has approved fully outpatient dosing in our Phase 2 trial starting in the second quarter of 2019.”

Testing a drug is safe before you give it to a pregnant woman

Pregnant woman holding medicine.

When a doctor gives you a medication you like to think that it’s safe, that it has been tested to make sure it will do you some good or, at the very least, won’t do you any harm. That’s particularly true when the patient is a pregnant woman. You hope the medication won’t harm her or her unborn child. Now scientists in Switzerland have found a new way to do that that is faster and easier than previous methods, and it uses cell cultures instead of animals.

Right now, drugs that are intended for use in pregnant women have to undergo some pretty rigorous testing before they are approved. This involves lots of tests in the lab, and then in animals such as rats and rabbits. It’s time consuming, costly, and not always accurate because animals never quite mimic what happens in people.

In the past researchers tested new medications in the lab on so-called “embryoid bodies”. These are three-dimensional clumps of cells developed from embryonic stem cells from mice. The problem is that even when tested in this way the cells don’t always reflect what happens to a medication as it passes through the body. For example, some medications can seem fine on the surface but after they pass through the liver can take on toxic qualities. 

So, scientists at ETH Zurich in Basel, Switzerland, developed a better way to test for toxicity.

They took a cell-culture chip and created several compartments on it, in some they placed the embryoid bodies and in others they put microtissue samples from human livers.  The different compartments were connected so that fluid flowed freely from the embryoid bodies to the liver and vice versa.

In a news release, Julia Boos, a lead author of the study, says this better reflects what happens to a medication exposed to a human metabolism.

“We’re the first to directly combine liver and embryonic cells in a body-on-a-chip approach. Metabolites created by the liver cells – including metabolites that are stable for just a few minutes – can thus act directly on the embryonic cells. In contrast to tests on mice, in our test, the substances are metabolised by human liver cells – in other words, just as they would be in the human body when the medication is administered.”

To see if this worked in practice the researchers tested their approach on the chemotherapy drug cyclophosphamide, which is turned into a toxic substance after passing through the liver.

They compared results from testing cyclophosphamide with the new liver/embryoid body method to the older method. They found the new approach was far more sensitive and determined that a 400 percent lower concentration of cyclophosphamide was enough to pose a toxic threat.

The team now hope to refine the test even further so it can one day, hopefully, be applied to drug development on a large scale.

Their findings are published in the journal Advanced Science

Stem cell model reveals deeper understanding into “ALS resilient” neurons

Understanding the basic biology of how a cell functions can be crucial to being able to better understand a disease and unlock a potential approach for a treatment. Stem cells are unique in that they give scientists the opportunity to create a controlled environment of cells that might be otherwise difficult to study. Dr. Eva Hedlund and a team of researchers at the Karolinska Institute in Sweden utilize a stem cell model approach to uncover findings related to Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig’s Disease.

ALS is a progressive neurodegenerative disease that destroys motor neurons, a type of nerve cell, that are important for voluntary muscle movement. When motor neurons can no longer send signals to the muscles, the muscles begin to deteriorate, a process formally known as atrophy. The progressive atrophy leads to muscle paralysis, including those in the legs and feet, arms and hands, and those that control swallowing and breathing. It affects about 30,000 people in the United States alone, with 5,000 new cases diagnosed each year. There is currently no cure.

In a previous study, researchers at the Karolinska Institute were able to successfully create oculomotor neurons from embryonic stem cells. For reasons not yet fully understood, oculomotor neurons are “ALS resilient” and can survive all stages of the disease.

In the current study, published in Stem Cell Reports, Dr. Hedlund and her team found that the oculomotor neurons they generated appeared more resilient to ALS-like degeneration when compared to spinal cord motor neurons, something commonly observed in humans. Furthermore, they discovered that their “ALS resilient” neurons generated from stem cells activate a survival-enhancing signal known as Akt, which is common in oculomotor neurons in humans and could explain their resilience. These results could potentially aid in identifying genetic targets for treatments protecting sensitive neurons from the disease.

In a press release, Dr. Hedlund is quoted as saying,

“This cell culture system can help identify new genes contributing to the resilience in oculomotor neurons that could be used in gene therapy to strengthen sensitive motor neurons.”

CIRM is currently funding two clinical trials for ALS, one of which is being conducted by Cedars-Sinai Medical Center and the other by Brainstorm Cell Therapeutics. The latter of the trials is currently recruiting patients and information on how to enroll can be found here.

CIRM-funded study helps unlock some of the genetic secrets behind macular degeneration

Retina affected by age-related macular degeneration

Age-related macular degeneration (AMD) is the leading cause of vision loss in people over 60. It affects 10 million Americans. That’s more than cataracts and glaucoma combined. The causes of AMD are not known but are believed to involve a mixture of hereditary and environmental factors. There is no treatment for it.

Now, in a CIRM-funded study, researchers at UC San Diego (UCSD) have used stem cells to help identify genetic elements that could provide some clues as to the cause, and maybe give some ideas on how to treat it.

Before we get into what the researchers did let’s take a look at what AMD does. At a basic level it attacks the retina, the thin layer of tissue that lines the back of the eye. The retina receives light, turns it into electrical signals and sends it to the brain which turns it into a visual image.

The disease destroys the macula, the part of the retina that controls our central vision. At first, sight becomes blurred or fuzzy but over time it progresses to the point where central vision is almost completely destroyed.

To try and understand why this happens the team at UCSD took skin samples from six people with AMD and, using the iPSC method, turned those cells into the kinds of cell found in the retina. Because these cells came from people who had AMD they now displayed the same characteristics as AMD-affected retinal cells. This allowed the researchers to create what is called a “disease-in-a-dish” model that allowed them to see, in real time, what is happening in AMD.

They were able to identify a genetic variant that reduces production of a protein called VEGFA, which is known to promote the growth of new blood vessels.

In a news release Kelly Frazer, director of the Institute for Genomic Medicine at UCSD and the lead author of the study, said the results were unexpected.

Kelly Frazer, PhD, UC San Diego

“We didn’t start with the VEGFA gene when we went looking for genetic causes of AMD. But we were surprised to find that with samples from just six people, this genetic variation clearly emerged as a causal factor.”

Frazer says this discovery, published in the journal Stem Cell Reports, could ultimately lead to new approaches to developing new treatments for AMD.

CIRM already funds one clinical trial-stage project targeting AMD.

3D brain model shows potential for treatment of hypoxic brain injuries in infants

A baby’s time in the womb is one of the most crucial periods in terms of its development. The average length of gestation, which is defined as the amount of time in the womb from conception to birth, is approximately 40 weeks. Unfortunately, for reasons not yet fully understood, there are times that babies are born prematurely, which can lead to problems.

These infants can have underdeveloped portions of the brain, such as the cerebral cortex, which is responsible for advanced brain functions, including cognition, speech, and the processing of sensory and motor information. The brains of premature infants can be so underdeveloped that they are unable to control breathing. This, in combination with underdeveloped lungs, can lower oxygen levels in the blood, which can lead to hypoxic, or low oxygen related, brain injuries.

In a previous study, doctors Anca and Sergiu Pasca and their colleagues at Stanford developed a technique to create a 3D brain that mimics structural and functional aspects of the developing human brain.

Using this same technique, in a new study with the aid of CIRM funding, the team grew a 3D brain that contained cells and genes similar to the human brain midway through the gestational period. They then exposed this 3D brain to low oxygen levels for 48 hours, restored the oxygen level after this time period, and observed any changes.

It was found that progenitor cells in a region known as the subventricular zone, a region that is critical in the growth of the human cortex, are affected. Progenitor cells are “stem cell like” cells that give rise to mature brain cells such as neurons. They also found that the progenitor cells transitioned from “growth” mode to “survival” mode, causing them to turn into neurons sooner than normal, which leads to fewer neurons in the brain and underdevelopment.

In a press release, Dr. Anca Pasca is quoted as saying,

“In the past 20 years, we’ve made a lot of progress in keeping extremely premature babies alive, but 70% to 80% of them have poor neurodevelopmental outcomes.”

The team then tested a small molecule to see if it could potentially reverse this response to low oxygen levels by keeping the progenitor cells in “growth” mode. The results of this are promising and Dr. Sergiu Pasca is quoted as saying,

“It’s exciting because our findings tell us that pharmacologically manipulating this pathway could interfere with hypoxic injury to the brain, and potentially help with preventing damage.”

The complete findings of this study were published in Nature.

The Past, the Present, and the Uncertain Future of Stem Cell Research

Ronnie, a boy who was born without a functioning immune system but who is thriving today because of CIRM funded research

When CIRM was created in 2004 the field of stem cell research was still very much in its infancy. Fast forward 15 years and it’s moving ahead at a rapid pace, probably faster than most scientists would have predicted. How fast? Find out for yourself at a free public event at UC San Diego on May 28th from 12.30 to 1.30p.

In the last 15 years CIRM has funded 53 clinical trials in everything from heart disease and stroke, to spinal cord injury, vision loss, sickle cell disease and HIV/AIDS.

UCSD was one of the first medical centers chosen to host a CIRM Alpha Stem Cell Clinic – a specialist center with the experience and expertise to deliver stem cell therapies to patients – and to date is running more than a dozen clinical trials for breast cancer, heart failure, leukemia and chronic lower back pain.

Clearly progress is being made. But the field is also facing some challenges. Funding at the federal level for stem cell research is under threat, and CIRM is entering what could be its final phase. We have enough money left to fund new projects through this year (and these are multi-year projects so they will run into 2021 or 2022) but unless there is a new round of funding we will slowly disappear. And with us, may also disappear the hopes of some of the most promising projects underway.

If CIRM goes, then projects that we have supported and nurtured through different phases of research may struggle to make it into a clinical trial because they can’t get the necessary funding.

Clearly this is a pivotal time in the field.

We will discuss all this, the past, the present and the uncertain future of stem cell research at the meeting at UC San Diego on May 28th. The doors will open at noon for registration (snacks and light refreshments will also be available) and the program runs from 12.30p to 1.30p.

The speakers are:

  • Dr. Catriona Jamieson, Director of the UC San Diego Health CIRM Alpha Stem Cell Clinic and Sanford Stem Cell Clinical Center.
  • Dr. Maria Millan, President and CEO of CIRM
  • Dr. David Higgins, CIRM Board member and Patient Advocate for Parkinson’s Disease.

And of course, we want to hear from you, so we’ll leave plenty of time for questions.

Free parking is available.

One year later, spinal cord therapy still looks promising

Jake Javier – participant in the SCIStar study

The beginning of a clinical trial, particularly the first time a new therapy is being tested in people, is often a time of equal parts anticipation and nervousness. Anticipation, because you have been working to this point for many years. Nervousness, because you have never tested this in people before and even though you have done years of study to show it is probably safe, until you try it in people you never really know.

That’s why the latest results from the CIRM-funded SCiStar Study, a clinical trial for spinal cord injury, are so encouraging. The results show that, one year after being treated, all the patients are doing well, none have experienced any serious side effects, and most have experienced impressive gains in movement, mobility and strength.

Ed Wirth, Chief Medical Officer at BioTime

In a news release Ed Wirth,  BioTIme’s Chief Medical Officer, said they were encouraged by what they saw:

“We believe the primary goals of the SCiStar Study, which were to observe the safety of OPC1 in cervical spinal cord injury patients as well as other important metrics including related to the optimal timing of OPC1 injection, tolerability of the immunosuppression regimen, engraftment of OPC1 cells, and rates of motor recovery observed among different study subpopulations, have all been successfully achieved.”

The study involved transplanting what the researchers called AST-OPC1 cells into patients who have suffered recent injuries that have left them paralyzed from the neck down.  AST-OPC1 are oligodendrocyte progenitor cells, which develop into cells that support and protect nerve cells in the central nervous system, the area damaged in spinal cord injury. It’s hoped the treatment will restore connections at the injury site, allowing patients to regain some movement and feeling.

Altogether 25 patients were involved. Three, in Cohort 1, were given injections of just two million OPC1 cells. This was to ensure the approach was safe and wouldn’t endanger patients. The remaining 22, in Cohorts 2-5, were given between 10 and 20 million cells. One year after the last patient was treated the results show:

  • MRI scans show no evidence of adverse changes in any of the 25 SCiStar study subjects.
    • No SCiStar study subjects had worsening of neurological function post-injection
    • At 12 months, 95% (21/22) of patients in Cohorts 2-5 recovered at least one motor level on at least one side and 32% (7/22) of these subjects recovered two or more motor levels on at least one side. 
    • No patient saw decreased motor function following administration of OPC1 and all either retained for 12 months the motor function recovery seen through 6 months or experienced further motor function recovery from 6 to 12 months.
    • All three subjects in Cohort 1 and 95% (21/22) of those in Cohorts 2 to 5 have MRI scans at 12 months consistent with the formation of a tissue matrix at the injury site. This is encouraging evidence the OPC1 cells have engrafted at the injury site and helped to prevent cavitation, a destructive process that occurs within the spinal cord following spinal cord injuries, and typically results in permanent loss of motor and sensory function.

“We appreciate the support of the California Institute for Regenerative Medicine, the world’s largest institution dedicated to bringing the future of cellular medicine closer to reality, whose generous grant funding to date of $14.3 million has helped advance the clinical development of our OPC1 program and generate these encouraging clinical results in patients with traumatic spinal cord injuries.”

BioTime is now planning to meet with the Food and Drug Administration (FDA) later this year to discuss next steps for the therapy. Soon as we know the outcome of those talks, we’ll share them with you.

CIRM Board Approves Funding for New Clinical Trials in Solid Tumors and Pediatric Disease

The governing Board of the California Institute for Regenerative Medicine (CIRM) awarded two grants totaling $11.15 million to carry out two new clinical trials.  These latest additions bring the total number of CIRM funded clinical trials to 53. 

$6.56 Million was awarded to Rocket Pharmaceuticals, Inc. to conduct a clinical trial for treatment of infants with Leukocyte Adhesion Deficiency-I (LAD-I)

LAD-I is a rare pediatric disease caused a mutation in a specific gene that affects the body’s ability to combat infections.  As a result, infants with severe LAD-I are often affected immediately after birth. During infancy, they suffer from recurrent life-threatening bacterial and fungal infections that respond poorly to antibiotics and require frequent hospitalizations.  Those that survive infancy experience recurrent severe infections, with mortality rates for severe LAD-I at 60-75% prior to the age of two and survival very rare beyond the age of five.

Rocket Pharmaceuticals, Inc. will test a treatment that uses a patient’s own blood stem cells and inserts a functional version of the gene.  These modified stem cells are then reintroduced back into the patient that would give rise to functional immune cells, thereby enabling the body to combat infections.  

The award is in the form of a CLIN2 grant, with the goal of conducting a clinical trial to assess the safety and effectiveness of this treatment in patients with LAD-I.

This project utilizes a gene therapy approach, similar to that of three other clinical trials funded by CIRM and conducted at UCLA by Dr. Don Kohn, for X-linked Chronic Granulomatous Disease, an inherited immune deficiency “bubble baby” disease known as ADA-SCID, and Sickle Cell Disease.

An additional $4.59 million was awarded to Dr. Theodore Nowicki at UCLA to conduct a clinical trial for treatment of patients with sarcomas and other advanced solid tumors. In 2018 alone, an estimated 13,040 people were diagnosed with soft tissue sarcoma (STS) in the United States, with approximately 5,150 deaths.  Standard of care treatment for sarcomas typically consists of surgery, radiation, and chemotherapy, but patients with late stage or recurring tumor growth have few options.

Dr. Nowicki and his team will genetically modify peripheral blood stem cells (PBSCs) and peripheral blood monocular cells (PBMCs) to target these solid tumors. The gene modified stem cells, which have the ability to self-renew, provide the potential for a durable effect.

This award is also in the form of a CLIN2 grant, with the goal of conducting a clinical trial to assess the safety of this rare solid tumor treatment.

This project will add to CIRM’s portfolio in stem cell approaches for difficult to treat cancers.  A previously funded a clinical trial at UCLA uses this same approach to treat patients with multiple myeloma.  CIRM has also previously funded two clinical trials using different approaches to target other types of solid tumors, one of which was conducted at Stanford and the other at UCLA. Lastly, two additional CIRM funded trials conducted by City of Hope and Poseida Therapeutics, Inc. used modified T cells to treat brain cancer and multiple myeloma, respectively.

“CIRM has funded 23 clinical stage programs utilizing cell and gene medicine approaches” says Maria T. Millan, M.D., the President and CEO of CIRM. “The addition of these two programs, one in immunodeficiency and the other for the treatment of malignancy, broaden the scope of unmet medical need we can impact with cell and gene therapeutic approaches.”

CIRM & NHLBI Create Landmark Agreement on Curing Sickle Cell Disease

CIRM Board approves first program eligible for co-funding under the agreement

Adrienne Shapiro, co-founder of Axis Advocacy, with her daughter Marissa Cors, who has Sickle Cell Disease.

Sickle Cell disease (SCD) is a painful, life-threatening blood disorder that affects around 100,000 people, mostly African Americans, in the US. Even with optimal medical care, SCD shortens expected lifespan by decades.  It is caused by a single genetic mutation that results in the production of “sickle” shaped red blood cells.  Under a variety of environmental conditions, stress or viral illness, these abnormal red blood cells cause severe anemia and blockage of blood vessels leading to painful crisis episodes, recurrent hospitalization, multi-organ damage and mini-strokes.    

On April 29th the governing Board of the California Institute for Regenerative Medicine (CIRM) approved $4.49 million to Dr. Mark Walters at UCSF Benioff Children’s Hospital in Oakland to pursue a gene therapy cure for this devastating disease. The gene therapy approach uses CRISPR-Cas9 technology to correct the genetic mutation that leads to sickle cell disease. This program will be eligible for co-funding under the landmark agreement between CIRM and the National Heart, Lung and Blood Institute (NHLBI) of the NIH.

This CIRM-NHLBI agreement was finalized this month to co-fund cell and gene therapy programs under the NIH “Cure Sickle Cell” initiative.  The goal is to markedly accelerate the development of cell and gene therapies for SCD. It will deploy CIRM’s resources and expertise that has led to a portfolio of over 50 clinical trials in stem cell and regenerative medicine.     

“CIRM currently has 23 clinical stage programs in cell and gene therapy.  Given the advancements in these approaches for a variety of unmet medical needs, we are excited about the prospect of leveraging this to NIH-NHLBI’s Cure Sickle Cell Initiative,” says Maria T. Millan, M.D., the President and CEO of CIRM. “We are pleased the NHLBI sees value in CIRM’s acceleration and funding program and look forward to the partnership to accelerate cures for sickle cell disease.”

“There is a real need for a new approach to treating SCD and making life easier for people with SCD and their families,” says Adrienne Shapiro, the mother of a daughter with SCD and the co-founder of Axis Advocacy, a sickle cell advocacy and education organization. “Finding a cure for Sickle Cell would mean that people like my daughter would no longer have to live their life in short spurts, constantly having their hopes and dreams derailed by ER visits and hospital stays.  It would mean they get a chance to live a long life, a healthy life, a normal life.”

CIRM is currently funding two other clinical trials for SCD using different approaches.  One of these trials is being conducted at City of Hope and the other trial is being conducted at UCLA.
