A year in review – CIRM’s 2017 Annual Report focuses on a year of accelerating stem cell treatments to patients

Facebook-AR-2017[3]

At CIRM we have our focus very clearly on the future, on accelerating stem cell therapies to patients with unmet medical needs. But every once in a while, it’s a good idea to look back at what you have already done. Knowing where you came from can help you get to where you are heading.

So, it’s with a sense of accomplishment that we are unveiling our 2017 Annual Report. It’s a look back at another banner year for the stem cell agency, the research we funded, the partnerships we created and, most importantly, the lives we touched.

It features profiles of several people who received stem cell therapies in CIRM-funded clinical trials and the impact those therapies are having on them. But it also looks at some of the other individuals who are such a vital part of the work we do: patient advocates, researchers and a member of our Grants Working Group which reviews applications for funding. Each one, in their own way, contributes to advancing the field.

The report also highlights some of the less obvious ways that our funding is benefitting California. For example, the additional $1.9 billion dollars our funding has helped generate through co-funding and partnerships, or the number of projects we are funding that have been awarded Regenerative Medicine Advanced Therapy Designation from the Food and Drug Administration (FDA), making them eligible for accelerated review if their results continue to be promising.

It’s a look back at a successful year.

But we are not resting on our laurels. We are already hard at work, determined to make 2018 even better.

Using the AIDS virus to help children battling a deadly immune disorder

More than 35 million people around the world have been killed by HIV, the virus that causes AIDS. So, it’s hard to think that the same approach the virus uses to infect cells could also be used to help children battling a deadly immune system disorder. But that’s precisely what researchers at UC San Francisco and St. Jude Children’s Research Hospital are doing.

The disease the researchers are tackling is a form of severe combined immunodeficiency (SCID). It’s also known as ‘bubble baby’ disease because children are born without a functioning immune system and in the past were protected from germs within the sterile environment of a plastic bubble. Children with this disease often die of infections, even from a common cold, in the first two years of life.

The therapy involves taking the patient’s own blood stem cells from their bone marrow, then genetically modifying them to correct the genetic mutation that causes SCID. The patient is then given low-doses of chemotherapy to create space in their bone marrow for the news cells. The gene-corrected stem cells are then transplanted back into the infant, creating a new blood supply and a repaired immune system.

Unique delivery system

The novel part of this approach is that the researchers are using an inactivated form of HIV as a means to deliver the correct gene into the patient’s cells. It’s well known that HIV is perfectly equipped to infiltrate cells, so by taking an inactivated form – meaning it cannot infect the individual with HIV – they are able to use that infiltrating ability for good.

The results were announced at the American Society of Hematology (ASH) Annual Meeting and Exposition in Atlanta.

The researchers say seven infants treated and followed for up to 12 months, have all produced the three major immune system cell types affected by SCID. In a news release, lead author Ewelina Mamcarz, said all the babies appear to be doing very well:

“It is very exciting that we observed restoration of all three very important cell types in the immune system. This is something that’s never been done in infants and a huge advantage over prior trials. The initial results also suggest our approach is fundamentally safer than previous attempts.”

One of the infants taking part in the trial is Ronnie Kashyap. We posted a video of his story on our blog, The Stem Cellar.

If the stem cell-gene therapy combination continues to show it is both safe and effective it would be a big step forward in treating SCID. Right now, the best treatment is a bone marrow transplant, but only around 20 percent of infants with SCID have a sibling or other donor who is a good match. The other 80 percent have to rely on a less well-matched bone marrow transplant – usually from a parent – that can still leave the child prone to life-threatening infections or potentially fatal complications such as graft-versus-host disease.

CIRM is funding two other clinical trials targeting SCID. You can read about them here and here.

Stories that caught our eye: How dying cells could help save lives; could modified blood stem cells reverse diabetes?; and FDA has good news for patients, bad news for rogue clinics

Gunsmoke

Growing up I loved watching old cowboy movies. Invariably the hero, even though mortally wounded, would manage to save the day and rescue the heroine and/or the town.

Now it seems some stem cells perform the same function, dying in order to save the lives of others.

Researchers at Kings College in London were trying to better understand Graft vs Host Disease (GvHD), a potentially fatal complication that can occur when a patient receives a blood stem cell transplant. In cases of GvHD, the transplanted donor cells turn on the patient and attack their healthy cells and tissues.

Some previous research had found that using bone marrow cells called mesenchymal stem cells (MSCs) had some success in combating GvHD. But it was unpredictable who it helped and why.

Working with mice, the Kings College team found that the MSCs were only effective if they died after being transplanted. It appears that it is only as they are dying that the MSCs engage with the individual’s immune system, telling it to stop attacking healthy tissues. The team also found that if they kill the MSCs just before transplanting them into mice, they were just as effective.

In a news article on HealthCanal, lead researcher Professor Francesco Dazzi, said the next step is to see if this will apply to, and help, people:

“The side effects of a stem cell transplant can be fatal and this factor is a serious consideration in deciding whether some people are suitable to undergo one. If we can be more confident that we can control these lethal complications in all patients, more people will be able to receive this life saving procedure. The next step will be to introduce clinical trials for patients with GvHD, either using the procedure only in patients with immune systems capable of killing mesenchymal stem cells, or killing these cells before they are infused into the patient, to see if this does indeed improve the success of treatment.”

The study is published in Science Translational Medicine.

Genetically modified blood stem cells reverse diabetes in mice (Todd Dubnicoff)

When functioning properly, the T cells of our immune system keep us healthy by detecting and killing off infected, damaged or cancerous cells in our body. But in the case of type 1 diabetes, a person’s own T cells turn against the body by mistakenly targeting and destroying perfectly normal islet cells in the pancreas, which are responsible for producing insulin. As a result, the insulin-dependent delivery of blood sugar to the energy-hungry organs is disrupted leading to many serious complications. Blood stem cell transplants have been performed to treat the disease by attempting to restart the immune system. The results have failed to provide a cure.

Now a new study, published in Science Translational Medicine, appears to explain why those previous attempts failed and how some genetic rejiggering could lead to a successful treatment for type 1 diabetes.

An analysis of the gene activity inside the blood stem cells of diabetic mice and humans reveals that these cells lack a protein called PD-L1. This protein is known to play an important role in putting the brakes on T cell activity. Because T cells are potent cell killers, it’s important for proteins like PD-L1 to keep the activated T cells in check.

Researchers from Boston Children’s Hospital hypothesized that adding back PD-L1 may prevent T cells from the indiscriminate killing of the body’s own insulin-producing cells. To test this idea, the research team genetically engineered mouse blood stem cells to produce the PD-L1 protein. Experiments with the cells in a petri dish showed that the addition of PD-L1 did indeed block the attack-on-self activity. And when these blood stem cells were transplanted into a diabetic mouse strain, the disease was reversed in most of the animals over the short term while a third of the mice had long-lasting benefits.

The researchers hope this targeting of PD-L1 production – which the researchers could also stimulate with pharmacological drugs – will contribute to a cure for type 1 diabetes.

FDA’s new guidelines for stem cell treatments

Gottlieb

FDA Commissioner Scott Gottlieb

Yesterday Scott Gottlieb, the Commissioner at the US Food and Drug Administration (FDA), laid out some new guidelines for the way the agency regulates stem cells and regenerative medicine. The news was good for patients, not so good for clinics offering unproven treatments.

First the good. Gottlieb announced new guidelines encouraging innovation in the development of stem cell therapies, and faster pathways for therapies, that show they are both safe and effective, to reach the patient.

At the same time, he detailed new rules that provide greater clarity about what clinics can do with stem cells without incurring the wrath of the FDA. Those guidelines detail the limits on the kinds of procedures clinics can offer and what ways they can “manipulate” those cells. Clinics that go beyond those limits could be in trouble.

In making the announcement Gottlieb said:

“To be clear, we remain committed to ensuring that patients have access to safe and effective regenerative medicine products as efficiently as possible. We are also committed to making sure we take action against products being unlawfully marketed that pose a potential significant risk to their safety. The framework we’re announcing today gives us the solid platform we need to continue to take enforcement action against a small number of clearly unscrupulous actors.”

Many of the details in the announcement match what CIRM has been pushing for some years. Randy Mills, our previous President and CEO, called for many of these changes in an Op Ed he co-wrote with former US Senator Bill Frist.

Our hope now is that the FDA continues to follow this promising path and turns these draft proposals into hard policy.

 

Progress to a Cure for Bubble Baby Disease

Welcome back to our “Throwback Thursday” series on the Stem Cellar. Over the years, we’ve accumulated an arsenal of exciting stem cell stories about advances towards stem cell-based cures for serious diseases. Today we’re featuring stories about the progress of CIRM-funded clinical trials for the treatment of a devastating, usually fatal, primary immune disease that strikes newborn babies.

‘Bubble baby disease’ will one day be a thing of the past. That’s a bold statement, but I say it with confidence because of the recent advancements in stem cell gene therapies that are curing infants of this life-threatening immune disease.

The scientific name for ‘bubble baby disease’ is severe combined immunodeficiency (SCID). It prevents the proper development of important immune cells called B and T cells, leaving newborns without a functioning immune system. Because of this, SCID babies are highly susceptible to deadly infections, and without treatment, most of these babies do not live past their first year. Even a simple cold virus can be fatal.

Scientists are working hard to develop stem cell-based gene therapies that will cure SCID babies in their first months of life before they succumb to infections. The technology involves taking blood stem cells from a patient’s bone marrow and genetically correcting the SCID mutation in the DNA of these cells. The corrected stem cells are then transplanted back into the patient where they can grow and regenerate a healthy immune system. Early-stage clinical trials testing these stem cell gene therapies are showing very encouraging results. We’ll share a few of these stories with you below.

CIRM-funded trials for SCID

CIRM is funding three clinical trials, one from UCLA, one at Stanford and one from UCSF & St. Jude Children’s Research Hospital, that are treating different forms of SCID using stem cell gene therapies.

Adenosine Deaminase-Deficient SCID

The first trial is targeting a form of the disease called adenosine deaminase-deficient SCID or ADA-SCID. Patients with ADA-SCID are unable to make an enzyme that is essential for the function of infection-fighting immune cells called lymphocytes. Without working lymphocytes, infants eventually are diagnosed with SCID at 6 months. ADA-SCID occurs in approximately 1 in 200,000 newborns and makes up 15% of SCID cases.

CIRM is funding a Phase 2 trial for ADA-SCID that is testing a stem cell gene therapy called OTL-101 developed by Dr. Don Kohn and his team at UCLA and a company called Orchard Therapeutics. 10 patients were treated in the trial, and amazingly, nine of these patients were cured of their disease. The 10th patient was a teenager who received the treatment knowing that it might not work as it does in infants. You can read more about this trial in our blog from earlier this year.

In a recent news release, Orchard Therapeutics announced that the US Food and Drug Administration (FDA) has awarded Rare Pediatric Disease Designation to OTL-101, meaning that the company will qualify for priority review for drug approval by the FDA. You can read more about what this designation means in this blog.

X-linked SCID

The second SCID trial CIRM is funding is treating patients with X-linked SCID. These patients have a genetic mutation on a gene located on the X-chromosome that causes the disease. Because of this, the disease usually affects boys who have inherited the mutation from their mothers. X-linked SCID is the most common form of SCID and appears in 1 in 60,000 infants.

UCSF and St. Jude Children’s Research Hospital are conducting a Phase 1/2 trial for X-linked SCID. The trial, led by Dr. Brian Sorrentino, is transplanting a patient’s own genetically modified blood stem cells back into their body to give them a healthy new immune system. Patients do receive chemotherapy to remove their diseased bone marrow, but doctors at UCSF are optimizing low doses of chemotherapy for each patient to minimize any long-term effects. According to a UCSF news release, the trial is planning to treat 15 children over the next five years. Some of these patients have already been treated and we will likely get updates on their progress next year.

CIRM is also funding a third clinical trial out of Stanford University that is hoping to make bone marrow transplants safer for X-linked SCID patients. The team, led by Dr. Judy Shizuru, is developing a therapy that will remove unhealthy blood stem cells from SCID patients to improve the survival and engraftment of healthy bone marrow transplants. You can read more about this trial on our clinical trials page.

SCID Patients Cured by Stem Cells

These clinical trial results are definitely exciting, but what is more exciting are the patient stories that we have to share. We’ve spoken with a few of the families whose children participated in the UCLA and UCSF/St. Jude trials, and we asked them to share their stories so that other families can know that there is hope. They are truly inspiring stories of heartbreak and joyful celebration.

Evie is a now six-year-old girl who was diagnosed with ADA-SCID when she was just a few months old. She is now cured thanks to Don Kohn and the UCLA trial. Her mom gave a very moving presentation about Evie’s journey at the CIRM Bridges Trainee Annual Meeting this past July.  You can watch the 20-minute talk below:

Ronnie, who is still less than a year old, was diagnosed with X-linked SCID just days after he was born. Luckily doctors told his parents about the UCSF/St. Jude trial and Ronnie was given the life-saving stem cell gene therapy before he was six months old. Now Ronnie is building a healthy immune system and is doing well back at home with his family. Ronnie’s dad Pawash shared his families moving story at our September Board meeting and you can watch it here.

Our mission at CIRM is to accelerate stem cell treatments to patients with unmet medical needs. We hope that by funding promising clinical trials like the ones mentioned in this blog, that one day soon there will be approved stem cell therapies for patients with SCID and other life-threatening diseases.

Using heart stem cells to help boys battling a deadly disorder

 

Caleb_Thumbnail3

Caleb Sizemore, a young man with DMD, speaks to the CIRM Board about his treatment in the Capricor clinical trial.

It’s hard to imagine how missing just one tiny protein can have such a devastating impact on a person. But with Duchenne Muscular Dystrophy (DMD) the lack of a single protein called dystrophin has deadly consequences. Now a new study is offering hope we may be able to help people with this rare genetic disorder.

DMD is a muscle wasting condition that steadily destroys the muscles in the arms and legs, heart and respiratory system. It affects mostly boys and it starts early in life, sometimes as young as 3 years old, and never lets up. By early teens many boys are unable to walk and are in a wheelchair. Their heart and breathing are also affected. In the past most people with DMD didn’t survive their teens. Now it’s more common for them to live into their 20’s and 30’s, but not much beyond that.

Results from a clinical trial being run by Capricor Therapeutics – and funded by CIRM – suggest we may be able to halt, and even reverse, some of the impacts of DMD.

Capricor has developed a therapy called CAP-1002 using cells derived from heart stem cells, called cardiospheres. Boys and young men with DMD who were treated with CAP-1002 experienced what Capricor calls “significant and sustained improvements in cardiac structure and function, as well as skeletal muscle function.”

In a news release Dr. Ronald Victor, a researcher at Cedars-Sinai Heart Institute and the lead investigator for the trial, said they followed these patients for 12 months after treatment and the results are encouraging:

“Because Duchenne muscular dystrophy is a devastating, muscle-wasting disease that causes physical debilitation and eventually heart failure, the improvements in heart and skeletal muscle in those treated with a single dose of CAP-1002 are very promising and show that a subsequent trial is warranted. These early results provide hope for the Duchenne community, which is in urgent need of a major therapeutic breakthrough.”

According to the 12-month results:

  • 89 percent of patients treated with CAP-1002 showed sustained or improved muscle function compared to untreated patients
  • The CAP-1002 group had improved heart muscle function compared to the untreated group
  • The CAP-1002 group had reduced scarring on their heart compared to the untreated group.

Now, these results are still very early stage and there’s a danger in reading too much into them. However, the fact that they are sustained over one year is a promising sign. Also, none of the treated patients experienced any serious side effects from the therapy.

The team at Capricor now plans to go back to the US Food and Drug Administration (FDA) to get clearance to launch an even larger study in 2018.

For a condition like DMD, that has no cure and where treatments can simply slow down the progression of the disorder, this is a hopeful start.

Caleb Sizemore is one of the people treated in this trial. You can read his story and listen to him describing the impact of the treatment on his life.

CIRM Board invests in three new stem cell clinical trials targeting arthritis, cancer and deadly infections

knee

Arthritis of the knee

Every day at CIRM we get calls from people looking for a stem cell therapy to help them fight a life-threatening or life-altering disease or condition. One of the most common calls is about osteoarthritis, a painful condition where the cartilage that helps cushion our joints is worn away, leaving bone to rub on bone. People call asking if we have something, anything, that might be able to help them. Now we do.

At yesterday’s CIRM Board meeting the Independent Citizens’ Oversight Committee or ICOC (the formal title of the Board) awarded almost $8.5 million to the California Institute for Biomedical Research (CALIBR) to test a drug that appears to help the body regenerate cartilage. In preclinical tests the drug, KA34, stimulated mesenchymal stem cells to turn into chondrocytes, the kind of cell found in healthy cartilage. It’s hoped these new cells will replace those killed off by osteoarthritis and repair the damage.

This is a Phase 1 clinical trial where the goal is primarily to make sure this approach is safe in patients. If the treatment also shows hints it’s working – and of course we hope it will – that’s a bonus which will need to be confirmed in later stage, and larger, clinical trials.

From a purely selfish perspective, it will be nice for us to be able to tell callers that we do have a clinical trial underway and are hopeful it could lead to an effective treatment. Right now the only alternatives for many patients are powerful opioids and pain killers, surgery, or turning to clinics that offer unproven stem cell therapies.

Targeting immune system cancer

The CIRM Board also awarded Poseida Therapeutics $19.8 million to target multiple myeloma, using the patient’s own genetically re-engineered stem cells. Multiple myeloma is caused when plasma cells, which are a type of white blood cell found in the bone marrow and are a key part of our immune system, turn cancerous and grow out of control.

As Dr. Maria Millan, CIRM’s President & CEO, said in a news release:

“Multiple myeloma disproportionately affects people over the age of 65 and African Americans, and it leads to progressive bone destruction, severe anemia, infectious complications and kidney and heart damage from abnormal proteins produced by the malignant plasma cells.  Less than half of patients with multiple myeloma live beyond 5 years. 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.”

In a news release from Poseida, CEO Dr. Eric Ostertag, said the therapy – called P-BCMA-101 – holds a lot of promise:

“P-BCMA-101 is elegantly designed with several key characteristics, including an exceptionally high concentration of stem cell memory T cells which has the potential to significantly improve durability of response to treatment.”

Deadly infections

The third clinical trial funded by the Board yesterday also uses T cells. Researchers at Children’s Hospital of Los Angeles were awarded $4.8 million for a Phase 1 clinical trial targeting potentially deadly infections in people who have a weakened immune system.

Viruses such as cytomegalovirus, Epstein-Barr, and adenovirus are commonly found in all of us, but our bodies are usually able to easily fight them off. However, patients with weakened immune systems resulting from chemotherapy, bone marrow or cord blood transplant often lack that ability to combat these viruses and it can prove fatal.

The researchers are taking T cells from healthy donors that have been genetically matched to the patient’s immune system and engineered to fight these viruses. The cells are then transplanted into the patient and will hopefully help boost their immune system’s ability to fight the virus and provide long-term protection.

Whenever you can tell someone who calls you, desperately looking for help, that you have something that might be able to help them, you can hear the relief on the other end of the line. Of course, we explain that these are only early-stage clinical trials and that we don’t know if they’ll work. But for someone who up until that point felt they had no options and, often, no hope, it’s welcome and encouraging news that progress is being made.

 

 

Turning the corner with the FDA and NIH; CIRM creates new collaborations to advance stem cell research

FDAThis blog is part of the Month of CIRM series on the Stem Cellar

A lot can change in a couple of years. Just take our relationship with the US Food and Drug Administration (FDA).

When we were putting together our Strategic Plan in 2015 we did a survey of key players and stakeholders at CIRM – Board members, researchers, patient advocates etc. – and a whopping 70 percent of them listed the FDA as the biggest impediment for the development of stem cell treatments.

As one stakeholder told us at the time:

“Is perfect becoming the enemy of better? One recent treatment touted by the FDA as a regulatory success had such a high clinical development hurdle placed on it that by the time it was finally approved the standard of care had evolved. When it was finally approved, five years later, its market potential had significantly eroded and the product failed commercially.”

Changing the conversation

To overcome these hurdles we set a goal of changing the regulatory landscape, finding a way to make the system faster and more efficient, but without reducing the emphasis on the safety of patients. One of the ways we did this was by launching our “Stem Cell Champions” campaign to engage patients, patient advocates, the public and everyone else who supports stem cell research to press for change at the FDA. We also worked with other organizations to help get the 21st Century Cures Act passed.

21 century cures

Today the regulatory landscape looks quite different than it did just a few years ago. Thanks to the 21st Century Cures Act the FDA has created expedited pathways for stem cell therapies that show promise. One of those is called the Regenerative Medicine Advanced Therapy (RMAT) designation, which gives projects that show they are both safe and effective in early-stage clinical trials the possibility of an accelerated review by the FDA. Of the first projects given RMAT designation, three were CIRM-funded projects (Humacyte, jCyte and Asterias)

Partnering with the NIH

Our work has also paved the way for a closer relationship with the National Institutes of Health (NIH), which is looking at CIRM as a model for advancing the field of regenerative medicine.

In recent years we have created a number of innovations including introducing CIRM 2.0, which dramatically improved our ability to fund the most promising research, making it faster, easier and more predictable for researchers to apply. We also created the Stem Cell Center  to make it easier to move the most promising research out of the lab and into clinical trials, and to give researchers the support they need to help make those trials successful. To address the need for high-quality stem cell clinical trials we created the CIRM Alpha Stem Cell Clinic Network. This is a network of leading medical centers around the state that specialize in delivering stem cell therapies, sharing best practices and creating new ways of making it as easy as possible for patients to get the care they need.

The NIH looked at these innovations and liked them. So much so they invited CIRM to come to Washington DC and talk about them. It was a great opportunity so, of course, we said yes. We expected them to carve out a few hours for us to chat. Instead they blocked out a day and a half and brought in the heads of their different divisions to hear what we had to say.

A model for the future

We hope the meeting is, to paraphrase Humphrey Bogart at the end of Casablanca, “the start of a beautiful friendship.” We are already seeing signs that it’s not just a passing whim. In July the NIH held a workshop that focused on what will it take to make genome editing technologies, like CRISPR, a clinical reality. Francis Collins, NIH Director, invited CIRM to be part of the workshop that included thought leaders from academia, industry and patients advocates. The workshop ended with a recommendation that the NIH should consider building a center of excellence in gene editing and transplantation, based on the CIRM model (my emphasis).  This would bring together a multidisciplinary disease team including, process development, cGMP manufacturing, regulatory and clinical development for Investigational New Drug (IND) filing and conducting clinical trials, all under one roof.

In preparation, the NIH visited the CIRM-funded Stem Cell Center at the City of Hope to explore ways to develop this collaboration. And the NIH has already begun implementing these suggestions starting with a treatment targeting sickle cell disease.

There are no guarantees in science. But we know that if you spend all your time banging your head against a door all you get is a headache. Today it feels like the FDA has opened the door and that, together with the NIH, they are more open to collaborating with organizations like CIRM. We have removed the headache, and created the possibility that by working together we truly can accelerate stem cell research and deliver the therapies that so many patients desperately need.

 

 

 

 

 

 

Getting faster, working smarter: how changing the way we work is paying big dividends

This blog is part of the Month of CIRM series

Speeding up the way you do things isn’t always a good idea. Just ask someone who got a ticket for going 65mph in a 30mph zone. But at CIRM we have found that doing things at an accelerated pace is paying off in a big way.

When CIRM started back in 2004 we were, in many ways, a unique organization. That meant we pretty much had to build everything from scratch, creating our own ways of asking for applications, reviewing those applications, funding them etc. Fast forward ten years and it was clear that, as good a job as we did in those early days, there was room for improvement in the way we operated.

So we made some changes. Big changes.

We adopted as our mantra the phrase “operational excellence.” It doesn’t exactly trip off the tongue but it does reflect what we were aiming for. The Business Dictionary defines operational excellence as:

 “A philosophy of the workplace where problem-solving, teamwork, and leadership results in the ongoing improvement in an organization.”

We didn’t want to just tinker with the way we worked, we wanted to reinvent every aspect of our operation. To do that we involved everyone in the operation. We held a series of meetings where everyone at CIRM, and I do mean everyone, was invited to join in and offer their ideas on how to improve our operation.

CIRM2.0_Logo

The end result was CIRM 2.0. At the time we described it as “a radical overhaul” of the way we worked. That might have been an understatement. We increased the speed, frequency and volume of the programs we offered, making it easier and more predictable for researchers to apply to us for funding, and faster for them to get that funding if they were approved.

For example, before 2.0 it took almost two years to go from applying for funding for a clinical trial to actually getting that funding. Today it takes around 120 days.

But it’s not just about speed. It’s also about working smarter. In the past if a researcher’s application for funding for a clinical trial failed it could be another 12 months before they got a chance to apply again. With many diseases 12 months could be a death sentence. So we changed the rules. Now if you have a project ready for a clinical trial you can apply any time. And instead of recommending or not recommending a project, basically voting it up or down, our independent panel of expert reviewers now give researchers with good but not great applications constructive feedback, enabling the researchers to make the changes needed to improve their project, and reapply for funding within 30 days.

This has not only increased the number of applications for clinical trials, it has also increased the quality of those applications.

We made similar changes in our Discovery and Translation programs. Increasing the frequency of each award, making it easier for researchers to know when the next round of funding was coming up. And we added incentives to encourage researchers to move successful projects on to the next level. We wanted to create a pipeline of the most promising projects steadily moving towards the clinic.

The motivation to do this comes from our patients. At CIRM we are in the time business. Many of the patients who are looking to stem cells to help them don’t have the luxury of time; they are rapidly running out of it. So we have a responsibility to do all we can to reduce the amount of time it takes to get the most promising therapies to them, without in any way compromising safety and jeopardizing their health.

By the end of 2016 those changes were very clearly paying dividends as we increased the frequency of reviews and the number of projects we reviewed but at the same time decreased the amount of time it took us to do all that.

Slide1

But we are not done yet. We have done a good job of improving the way we work. But there is always room to be even better, to go even faster and be more efficient.

We are not done accelerating. Not by a long shot.

Streamlining Stem Cell Therapy Development for Impatient Patients

During this third week of the Month of CIRM, we are focusing on CIRM’s Infrastructure programs which are all focused on helping to accelerate stem cell treatments to patients with unmet medical needs.

Time is money. It’s a cliché but still very true, especially in running a business. The longer it takes to get things done, the more costs you’ll most likely face. But in the business of developing new medical therapies, time is also people’s lives.

Currently, it takes about eight years to move a promising stem cell treatment from the lab into clinical trials. For patients with fatal, incurable diseases, that is eight years too long. And even when promising therapies reach clinical trials, only about 1 out of 10 get approved, according to a comprehensive 2014 study in Nature Biotechnology. These sobering stats slow the process of getting treatments to patients with unmet medical needs.

While a lack of therapy effectiveness or safety play into the low success rate, other factors can have a significant impact on the delay or suspension of a trial. An article, “Why Do Clinical Trials Fail?” in Clinical Trials Arena from a couple years back outlined a few. Here’s a snippet from that article:

  • “Poor study design: Selecting the wrong patients, the wrong dosing and the wrong endpoint, as well as bad data and bad site management cause severe problems.”
  • “Complex protocol: Simple is better. A complex protocol, which refers to trying to answer too many questions in one single trial, can produce faulty data and contradictory results.”
  • “Poor management: A project manager who does not have enough experience in costing and conducting clinical trials will lead to weak planning, with no clear and real timelines, and to ultimate failure.”

CIRM recognized that these clinical trial planning and execution setbacks can stem from the fact that, although lab researchers are experts at transforming an idea into a candidate therapy, they may not be masters in navigating the complex regulatory requirements of the Food and Drug Administration (FDA). Many simply don’t have the experience to get those therapies off the ground by themselves.

Lab researchers are experts at transforming an idea into a candidate therapy but most are inexperienced at navigating the complex regulatory requirements of the Food and Drug Administration (FDA).

So, to help make this piece of the therapy development process more efficient and faster, the CIRM governing Board last year approved the launch of the Translating Center and Accelerating Center: two novel infrastructure programs which CIRM grantees can tap into as they carry their promising candidate therapies from lab experiments in cells to preclinical studies in animals to clinical trials in people. Both centers were awarded to QuintilesIMS which collectively dubbed them The Stem Cell Center.

The Stem Cell Center acts as a one-stop-shop, stem cell therapy development support system for current and prospective CIRM grantees, giving them advanced priority for QuintilesIMS services. So how does it work? When a scientist’s initial idea for a cell therapy gains traction and, through a lot of effort in the lab, matures into a bona fide therapy candidate to treat a particular disease, the next big step is to prepare the therapy for testing in people. But that’s easier said than done. To ensure safety, the Food and Drug Administration requires a rigorous set of tests and documentation that make up an Investigational New Drug (IND) application, which must be submitted before any testing in people take can place in the U.S.

That’s where the Translation Center comes into the picture. It carries out the necessary research activities to show, as much as is possible in animals, that the therapy is safe. The Translating Center also helps at this stage with manufacturing the cell therapy product so that it’s of a consistent quality for both the preclinical and future clinical trial studies. If all goes as planned, the grantee will have the necessary pieces to file an IND. At this stage, the Translating Center coordinates with the Accelerating Center which focuses on supporting the many facets of a clinical study including the IND filing, clinical trial design, monitoring of patient safety, and project management.

Because the work of Translating and Accelerating Centers is focused on these regulatory activities day in and day out, they have the know-how to pave a clearer path, with fewer pitfalls, for the grantee to navigate the complex maze we call cell therapy development. It’s not just helpful for the researchers seeking approval from the FDA, but it helps the FDA too. Because cell therapies are still so new, creating a standardized, uniform approach to stem cell-based clinical trial projects will help the FDA streamline their evaluation of the projects.

Ultimately, and most importantly, all of those gears running smoothly in sync will help leave a lasting legacy for California and the world: an acceleration in the development of stem cell treatment for patients with unmet medical needs.

Stem Cell Stories that Caught Our Eye: New law to protect consumers; using skin to monitor blood sugar; and a win for the good guys

Hernendez

State Senator Ed Hernandez

New law targets stem cell clinics that offer therapies not approved by the FDA

For some time now CIRM and others around California have been warning consumers about the risks involved in going to clinics that offer stem cell therapies that have not been tested in a clinical trial or approved by the U.S. Food and Drug Administration (FDA) for use in patients.

Now a new California law, authored by State Senator Ed Hernandez (D-West Covina) attempts to address that issue. It will require medical clinics whose stem cell treatments are not FDA approved, to post notices and provide handouts to patients warning them about the potential risk.

In a news release Sen. Hernandez said he hopes the new law, SB 512, will protect consumers from early-stage, unproven experimental therapies:

“There are currently over 100 medical offices in California providing non-FDA approved stem cell treatments. Patients spend thousands of dollars on these treatments, but are totally unaware of potential risks and dangerous side effects.”

Sen. Hernandez’s staffer Bao-Ngoc Nguyen crafted the bill, with help from CIRM Board Vice Chair Sen. Art Torres, Geoff Lomax and UC Davis researcher Paul Knoepfler, to ensure it targeted only clinics offering non-FDA approved therapies and not those offering FDA-sanctioned clinical trials.

For example the bill would not affect CIRM’s Alpha Stem Cell Clinic Network because all the therapies offered there have been given the green light by the FDA to work with patients.

Blood_Glucose_Testing 

Using your own skin as a blood glucose monitor

One of the many things that people with diabetes hate is the constant need to monitor their blood sugar level. Usually that involves a finger prick to get a drop of blood. It’s simple but not much fun. Attempts to develop non-invasive monitors have been tried but with limited success.

Now researchers at the University of Chicago have come up with another alternative, using the person’s own skin to measure their blood glucose level.

Xiaoyang Wu and his team accomplished this feat in mice by first creating new skin from stem cells. Then, using the gene-editing tool CRISPR, they added in a protein that sticks to sugar molecules and another protein that acts as a fluorescent marker. The hope was that the when the protein sticks to sugar in the blood it would change shape and emit fluorescence which could indicate if blood glucose levels were too high, too low, or just right.

The team then grafted the skin cells back onto the mouse. When those mice were left hungry for a while then given a big dose of sugar, the skin “sensors” reacted within 30 seconds.

The researchers say they are now exploring ways that their findings, published on the website bioRxiv, could be duplicated in people.

While they are doing that, we are supporting ViaCytes attempt to develop a device that doesn’t just monitor blood sugar levels but also delivers insulin when needed. You can read about our recent award to ViaCyte here.

Deepak

Dr. Deepak Srivastava

Stem Cell Champion, CIRM grantee, and all-round-nice guy named President of Gladstone Institutes

I don’t think it would shock anyone to know that there are a few prima donnas in the world of stem cell research. Happily, Dr. Deepak Srivastava is not one of them, which makes it such a delight to hear that he has been appointed as the next President of the Gladstone Institutes in San Francisco.

Deepak is a gifted scientist – which is why we have funded his work – a terrific communicator and a really lovely fella; straight forward and down to earth.

In a news release announcing his appointment – his term starts January 1 next year – Deepak said he is honored to succeed the current President, Sandy Williams:

“I joined Gladstone in 2005 because of its unique ability to leverage diverse basic science approaches through teams of scientists focused on achieving scientific breakthroughs for mankind’s most devastating diseases. I look forward to continue shaping this innovative approach to overcome human disease.”

We wish him great success in his new role.
