Identifying the visually impaired patients most likely to benefit from jCyte’s stem cell therapy

We have written about jCyte many times on The Stem Cellar. For one reason, they are showing really encouraging results in their treatment for retinitis pigmentosa (RP). And now they have taken an even deeper dive into those results and identified which patients may be most likely to benefit from the therapy.

RP is a rare genetic disorder that slowly destroys the rods and cones, the light sensing cells in the back of the eye. If you look at the image below the one on the left shows normal vision, the one on the right shows what happens with RP. At first you start to lose night vision, then other parts of your vision are slowly eroded until you are legally blind.

RP starts early, often people are diagnosed in their teens and are legally blind by middle age. There is no treatment, no cure. It’s estimated that as many as 100,000 people in the US have RP, as many as two million worldwide.

That’s where jCyte comes in. They developed jCell, a therapy using adult stem cells that have been changed into human retinal progenitor cells (hRPCs). These are injected into the back of the eye where they secrete small proteins called neurotrophic factors.

Dr. Henry Klassen, one of the founders of jCyte, says jCell works by preserving the remaining photoreceptors in the eye, and helping them bounce back.

“Typically, people think about the disease as a narrowing of this peripheral vision in a very nice granular way, but that’s actually not what happens. What happens in the disease is that patients lose like islands of vision. So, what we’re doing in our tests is actually measuring […] islands that the patients have at baseline, and then what we’re seeing after treatment is that the islands are expanding. It’s similar to the way that one would track, let’s say a tumor, in oncology of course we’re looking for the opposite effect. We’re looking for the islands of vision to expand.”

And in patients treated with jCell those islands of vision did expand. The team followed patients for one-year post treatment and found that patients given the highest dose, six million cells, experienced the biggest improvement and were able to read, on average, 16 more letters on a standard eye chart than they had been before treatment. In comparison people given a sham or placebo treatment only had an improvement of less than two letters.

This group also experienced improvements in their peripheral vision, their ability to distinguish objects in the foreground from the background and were better able to get around in low light.

But that’s not all. Dr. Sunil Srivastava, with the Cleveland Clinic Cole Eye Institute, did a detailed analysis of patients treated in the trial and identified central foveal thickness (CFT- the part of the eye located in the center of the retina) as an important marker for who would be most likely to benefit from jCell. People who started out with a higher CFT score were most likely to get the biggest benefits.

In a news release, jCyte CEO Dr. Shannon Blalock said the findings are really encouraging: “We look forward to working closely with our scientific advisory board and principal investigators to apply these key learnings to our upcoming pivotal study of jCell to optimize its probability of success in an effort to advance the clinical development program of our RMAT designated therapy for RP patients who currently have no treatment options.”

Charting a course for the future

A new home for stem cell research?

Have you ever been at a party where someone says “hey, I’ve got a good idea” and then before you know it everyone in the room is adding to it with ideas and suggestions of their own and suddenly you find yourself with 27 pages of notes, all of them really great ideas. No, me neither. At least, not until yesterday when we held the first meeting of our Scientific Strategy Advisory Panel.

This is a group that was set up as part of Proposition 14, the ballot initiative that refunded CIRM last November (thanks again everyone who voted for that). The idea was to create a panel of world class scientists and regulatory experts to help guide and advise our Board on how to advance our mission. It’s a pretty impressive group too. You can see who is on the SSAP here.  

The meeting involved some CIRM grantees talking a little about their work but mostly highlighting problems or obstacles they considered key issues for the future of the field as a whole. And that’s where the ideas and suggestions really started flowing hard and fast.

It started out innocently enough with Dr. Amander Clark of UCLA talking about some of the needs for Discovery or basic research. She advocated for a consortium approach (this quickly became a theme for many other experts) with researchers collaborating and sharing data and findings to help move the field along.

She also called for greater diversity in research, including collecting diverse cell samples at the basic research level, so that if a program advanced to later stages the findings would be relevant to a wide cross section of society rather than just a narrow group.

Dr. Clark also said that as well as supporting research into neurodegenerative diseases, such as Alzheimer’s and Parkinson’s, there needed to be a greater emphasis on neurological conditions such as autism, bipolar disorder and other mental health problems.

(CIRM is already committed to both increasing diversity at all levels of research and expanding mental health research so this was welcome confirmation we are on the right track).

Dr. Mike McCun called for CIRM to take a leadership role in funding fetal tissue research, things the federal government can’t or won’t support, saying this could really help in developing an understanding of prenatal diseases.

Dr. Christine Mummery, President of ISSCR, advocated for support for early embryo research to deepen our understanding of early human development and also help with issues of infertility.

Then the ideas started coming really fast:

  • There’s a need for knowledge networks to share information in real-time not months later after results are published.
  • We need standardization across the field to make it easier to compare study results.
  • We need automation to reduce inconsistency in things like feeding and growing cells, manufacturing cells etc.
  • Equitable access to CRISPR gene-editing treatments, particularly for underserved communities and for rare diseases where big pharmaceutical companies are less likely to invest the money needed to develop a treatment.
  • Do a better job of developing combination therapies – involving stem cells and more traditional medications.

One idea that seemed to generate a lot of enthusiasm – perhaps as much due to the name that Patrik Brundin of the Van Andel Institute gave it – was the creation of a CIRM Hotel California, a place where researchers could go to learn new techniques, to share ideas, to collaborate and maybe take a nice cold drink by the pool (OK, I just made that last bit up to see if you were paying attention).

The meeting was remarkable not just for the flood of ideas, but also for its sense of collegiality.  Peter Marks, the director of the Food and Drug Administration’s Center for Biologics Evaluation and Research (FDA-CBER) captured that sense perfectly when he said the point of everyone working together, collaborating, sharing information and data, is to get these projects over the finish line. The more we work together, the more we will succeed.

Anticipating the Future of Regenerative Medicine: CIRM’s Alpha Stem Cell Clinics Network

All this month we are using our blog and social media to highlight a new chapter in CIRM’s life, thanks to the voters approving Proposition 14. We are looking back at what we have done since we were created in 2004, and also looking forward to the future. Today we take a deeper dive into CIRM’s Alpha Stem Cell Clinics Network.  The following is written by Dr. Geoff Lomax, Senior Officer of CIRM Therapeutics and Strategic Infrastructure.

The year 2014 has been described as the regenerative medicine renaissance: the European Union approved its first stem cell-based therapy and the FDA authorized ViaCyte’s CIRM funded clinical trial for diabetes. A path forward for stem cell treatments had emerged and there was a growing pipeline of products moving towards the clinic. At the time, many in the field came to recognize the need for clinical trial sites with the expertise to manage this growing pipeline. Anticipating this demand, CIRM’s provided funding for a network of medical centers capable of supporting all aspect of regenerative medicine clinical trials. In 2015, the Alpha Stem Cell Clinics Network was launched to for this purpose.

The Alpha Clinics Network is comprised of leading California medical centers with specific expertise in delivering patient-centered stem cell and gene therapy treatments. UC San Diego, City of Hope, UC Irvine and UC Los Angeles were included in the initial launch, and UC San Francisco and UC Davis entered the network in 2017. Between 2015 and 2020 these sites supported 105 regenerative medicine clinical trials. Twenty-three were CIRM-funded clinical trials and the remaining 82 were sponsored by commercial companies or the Alpha Clinic site. These trials are addressing unmet medical needs for almost every disease where regenerative medicine is showing promise including blindness, blood disorders (e.g. sickle cell disease) cancer, diabetes, HIV/AIDS, neurological diseases among others.

As of spring of 2020 the network had inked over $57 million in contracts with commercial sponsors. High demand for Alpha Clinics reflects the valuable human and technical resources they provide clinical trial sponsors. These resources include:

  • Skilled patient navigators to educate patients and their families about stem cell and gene therapy treatments and assist them through the clinical trial process.
  • Teams and facilities specialized in the manufacturing and/or processing of patients’ treatments. In some instances, multiple Alpha Clinic sites collaborate in manufacturing and delivery of a personalized treatment to the patient.
  • Nurses and clinicians with experience with regenerative medicine and research protocols to effectively deliver treatments and subsequently monitor the patients.

The multi- site collaborations are an example of how the network operates synergistically to accelerate the development of new treatments and clinical trials. For example, the UC San Francisco Alpha Clinic is collaborating with UC Berkeley and the UC Los Angeles Alpha Clinic to develop a CIRM-funded gene therapy for sickle cell disease. Each partner brings a unique expertise to the program that aims to correct a genetic mutilation in the patients’ blood stem cells to effectively cure the disease. Most recently, City of Hope has partnered with UC Irvine and UC San Diego as part of CIRM’s COVID-19 research program to study how certain immune system antibodies might be used as a treatment for respiratory disease in infected patients. In another COVID-19 study, UC Irvine and UC Davis are working with a commercial sponsor to evaluate a treatment for infected adults.

The examples above are a small sample of the variety of collaborations CIRM funding has enabled. As the Alpha Clinics track record grown, sponsors are increasingly coming to California to enable the success of their research programs. Sponsors with trials running across the country have noted a desire to expand their number of Alpha Clinic sties because they consistently perform at the highest level.

Back in 2014, it was hard to imagine over one hundred clinical trials would be served by the CIRM network in just five years. Fortunately, CIRM was able to draw on the knowledge of its internal team, external advisors and the ICOC to anticipate this need and provide California infrastructure to rise to the occasion.

Inspiring new documentary about stem cell research

Poster for the documentary “Ending Disease”

2020 has been, to say the very least, a difficult and challenging year for all of us. But while the focus of the world has, understandably, been on the coronavirus there was also some really promising advances in stem cell research. Those advances are captured in a great new documentary called Ending Disease.

The documentary is by Emmy award-winning filmmaker Joe Gantz. In it he follows ten people who are facing life-threatening or life-changing diseases and injuries and who turn to pioneering stem cell therapies for help.

It’s an inspiring documentary, one that reminds you of the real need for new treatments and the tremendous hope and promise of stem cell therapies. Here’s a look at a trailer for Ending Disease.

You can see an exclusive screening of Ending Disease on Friday, January 8th, 2021 at 5:00pm PST.

After the livestream, there will be a live Q&A session where former members of the successful Proposition 14 campaign team – which refunded CIRM with an additional $5.5 billion – will be joined by CIRM’s President and CEO Dr. Maria Millan, talking about what lies ahead for CIRM and the future of stem cell research.

To purchase a ticket, click here. It only costs $12 and 50% of the ticket sales proceeds will go to Americans for Cures to help them continue to advocate for the advancement of stem cell research, and more importantly, for the patients and families to whom stem cell research provides so much hope.

If you need any extra persuading that it’s something you should definitely put on our calendar, here’s a letter from the film maker Joe Gantz.

I am the director of the documentary Ending Disease: The Stem Cell, Anti-Cancer T-Cell, & Antibody Revolution In Medicine, a film that will help inform people about the progress that’s been made in this field and how people with their lives on the line are now able to benefit from these new regenerative therapies. 

I was granted unprecedented access to ten of the first generation of clinical trials using stem cell and regenerative medicine to treat and cure many of the most devastating diseases and conditions including: brain cancer, breast cancer, leukemia and lymphoma, HIV, repairing a broken spinal cord, retinitis pigmentosa and SCID. The results are truly inspiring.

This is personal for me.  After spending four years making this documentary, I was diagnosed with bladder cancer. Upon diagnosis, I immediately felt the same desperation as millions of families who are in search of a medical breakthrough. I understood, on a personal level, what the patients we followed in the film all knew: when you are diagnosed with a disease, there is a narrow window of time in which you can effectively seek a life-saving treatment or cure. If treatment becomes available outside of that window, then it is too late. However, Ending Disease shows that with continued support for regenerative medicine, we can create a near future in which one-time cures and highly mitigating therapies are available to patients for a whole host of diseases.

Best regards,

Joe

Patient that has recovered from Covid-19 donating blood plasma. Photo courtesy Science Photo

Convalescent plasma has been in the news a lot lately as a potential treatment for people infected with the coronavirus. In August the US Food and Drug Administration (FDA) granted emergency use authorization (EUA) to use these products based on preliminary data that suggested it might help people battling COVID. But there are still a lot of unanswered questions about this approach.

And that’s where you come in.

Plasma is a component of blood that carries proteins called antibodies that are usually involved in defending our bodies against viral infections.  We also know that blood plasma from patients that have recovered from COVID-19, referred to as convalescent plasma, contain antibodies against the virus that can be used as a potential treatment for COVID-19. 

That’s the theory, but the reality is that there are still a lot we don’t know, basic questions such as does it really work, how does it work, does it work for everyone or just some patients? A clinical  grant includes testing the plasma in COVID-19 Positive patients that CIRM is funding with City of Hope, UC Irvine and Translational Genomics Research Institute (TGen) hopes to answer those questions. 

The first step is getting the plasma from people who have recovered from COVID and then testing it to make sure it’s safe and to identify what blood type it is, so you can match that blood type with the person receiving it.

But plasma doesn’t contain just one kind of antibody, there are many antibodies and each one works in a slightly different way. For example, two antibodies, IGM and IGG, target in on the spike protein on the coronavirus. The goal is to block that spike and prevent the virus from spreading throughout the body. IGM has up to 10 ‘arms’ and so has the potential to bind multiple copies of the spike, whereas IGG has only 2 arms, but lasts longer. Both IGM and IGG also come in many different flavors, allowing them to bind to many different parts of the spike, some being more protective than others.

That’s one of the things that this trial is trying to find out. And you can help them do that. The trial needs volunteers, volunteers to donate the plasma and volunteers to try the therapy.

The team is evaluating changes that occur before and after plasma treatment.  Many recipients have no immediate response, a few get dramatically better, and some continue to have symptoms long after discharge from the hospital.  These so-called “long-haulers” can have debilitating problems, months after becoming infected. The study hopes to evaluate these variable responses to plasma treatment.

But more people are needed if we are to truly understand what works best. We need people who are newly infected, those being treated with plasma, and those that have recovered from the virus.

We are particularly interested in recruiting people from the Black and Latinx communities, groups that are often underserved when it comes to access to medical care.

The team has created a website to make it easy to find out more about the clinical trial, and to see if you are a good candidate to be part of it, either as a donor or recipient.

Lives are at stake and time is short so join us, help us find answers to the most pressing medical issue of our times. It’s a chance to do something that might benefit your family, your friends and your community.

Cures, clinical trials and unmet medical needs

When you have a great story to tell there’s no shame in repeating it as often as you can. After all, not everyone gets to hear first time around. Or second or third time. So that’s why we wanted to give you another opportunity to tune into some of the great presentations and discussions at our recent CIRM Alpha Stem Cell Clinic Network Symposium.

It was a day of fascinating science, heart-warming, and heart-breaking, stories. A day to celebrate the progress being made and to discuss the challenges that still lie ahead.

There is a wide selection of topics from “Driving Towards a Cure” – which looks at some pioneering work being done in research targeting type 1 diabetes and HIV/AIDS – to Cancer Clinical Trials, that looks at therapies for multiple myeloma, brain cancer and leukemia.

The COVID-19 pandemic also proved the background for two detailed discussions on our funding for projects targeting the coronavirus, and for how the lessons learned from the pandemic can help us be more responsive to the needs of underserved communities.

Here’s the agenda for the day and with each topic there’s a link to the video of the presentation and conversation.

Exploring tough questions, looking for answers

COVID-19 and social and racial injustice are two of the biggest challenges facing the US right now. This Thursday, October 8th, we are holding a conversation that explores finding answers to both.

The CIRM Alpha Stem Cell Clinic Network Symposium is going to feature presentations about advances in stem cell and regenerative research, highlighting treatments that are already in the clinic and being offered to patients.

But we’re also going to dive a little deeper into the work we support, and use it to discuss two of the most pressing issues of the day.

One of the topics being featured is research into COVID-19. To date CIRM has funded 17 different projects, including three clinical trials. We’ll talk about how these are trying to find ways to help people infected with the virus, seeing if stem cells can help restore function to organs and tissues damaged by the virus, and if we can use stem cells to help develop safe and effective vaccines.

Immediately after that we are going to use COVID-19 as a way of exploring how the people most at risk of being infected and suffering serious consequences, are also the ones most likely to be left out of the research and have most trouble accessing treatments and vaccines.

Study after study highlights how racial and ethnic minorities are underrepresented in clinical trials and disproportionately affected by debilitating diseases. We have a responsibility to change that, to ensure that the underserved are given the same opportunity to take part in clinical trials as other communities.

How do we do that, how do we change a system that has resisted change for so long, how do we overcome the mistrust that has built up in underserved communities following decades of abuse? We’ll be talking about with experts who are on the front lines of this movement.

It promises to be a lively meeting. We’d love to see you there. It’s virtual – of course – it’s open to everyone, and it’s free.

Here’s where you can register and find out more about the Symposium

It’s all about the patients

Whenever you are designing something new you always have to keep in mind who the end user is. You can make something that works perfectly fine for you, but if it doesn’t work for the end user, the people who are going to work with it day in and day out, you have been wasting your time. And their time too.

At CIRM our end users are the patients. Everything we do is about them. Starting with our mission statement: to accelerate stem cell treatments to patients with unmet medical needs. Everything we do, every decision we make, has to keep the needs of the patient in mind.

So, when we were planning our recent 2020 Grantee Meeting (with our great friends and co-hosts UC Irvine and UC San Diego) one of the things we wanted to make sure didn’t get lost in the mix was the face and the voice of the patients. Often big conferences like this are heavy on science with presentations from some of the leading researchers in the field. And we obviously wanted to make sure we had that element at the Grantee meeting. But we also wanted to make sure that the patient experience was front and center.

And we did just that. But more on that in a minute. First, let’s talk about why the voice of the patient is important.

Some years ago, Dr. David Higgins, a CIRM Board member and patient advocate for Parkinson’s Disease (PD), said that when researchers are talking about finding treatments for PD they often focus on the dyskinesia, the trembling and shaking and muscle problems. However, he said if you actually asked people with PD you’d find they were more concerned with other aspects of the disease, the insomnia, anxiety and depression among other things. The key is you have to ask.

Frances Saldana, a patient advocate for research into Huntington’s disease

So, we asked some of our patient advocates if they would be willing to be part of the Grantee Meeting. All of them, without hesitation, said yes. They included Frances Saldana, a mother who lost three of her children to Huntington’s disease; Kristin MacDonald, who lost her sight to a rare disorder but regained some vision thanks to a stem cell therapy and is hoping the same therapy will help restore some more; Pawash Priyank, whose son Ronnie was born with a fatal immune disorder but who, thanks to a stem cell/gene therapy treatment, is now healthy and leading a normal life.

Because of the pandemic everything was virtual, but it was no less compelling for that. We interviewed each of the patients or patient advocates beforehand and those videos kicked off each session. Hearing, and seeing, the patients and patient advocates tell their stories set the scene for what followed. It meant that the research the scientists talked about took on added significance. We now had faces and names to highlight the importance of the work the scientists were doing. We had human stories. And that gave a sense of urgency to the work the researchers were doing.

But that wasn’t all. After all the video presentations each session ended with a “live” panel discussion. And again, the patients and patient advocates were a key part of that. Because when scientists talk about taking their work into a clinical trial they need to know if the way they are setting up the trial is going to work for the patients they’re hoping to recruit. You can have the best scientists, the most promising therapy, but if you don’t design a clinical trial in a way that makes it easy for patients to be part of it you won’t be able to recruit or retain the people you need to test the therapy.

Patient voices count. Patient stories count.

But more than anything, hearing and seeing the people we are trying to help reminds us why we do this work. It’s so easy to get caught up in the day to day business of our jobs, struggling to get an experiment to work, racing to get a grant application in before the deadline. Sometimes we get so caught up in the minutiae of work we lose sight of why we are doing it. Or who we are doing it for.

At CIRM we have a saying; come to work every day as if lives depend on you, because lives depend on you. Listening to the voices of patients, seeing their faces, hearing their stories, reminds us not to waste a moment. Because lives depend on all of us.

Here’s one of the interviews that was featured at the event. I do apologize in advance for the interviewer, he’s rubbish at his job.

CIRM-funded kidney transplant procedure eyeing faster approval

Kidney transplant surgery.

Medeor Therapeutics, which is running a CIRM-funded clinical trial to help people getting kidney transplants, just got some really good news. The US Food and Drug Administration (FDA) has just granted their product Regenerative Medicine Advanced Therapy (RMAT) designation. That’s a big deal because it means they may be able to apply for faster review and approval and get their therapy to more patients faster.

Here’s why that RMAT designation matters.

Over 650,000 Americans suffer from end-stage kidney disease – a life-threatening condition caused by the loss of kidney function. The best available treatment for these patients is a kidney transplant from a genetically matched living donor. However, patients who receive a transplant must take life-long immunosuppressive drugs to prevent their immune system from rejecting the transplanted organ. Over time, these drugs are toxic and can increase a patient’s risk of infection, heart disease, cancer and diabetes.  Despite these drugs, many patients still lose transplanted organs due to rejection.

To tackle this problem Medeor is developing a stem cell-based therapy called MDR-101. This is being tested in a Phase 3 clinical trial and it’s hoped it will eliminate the need for immunosuppressive drugs in genetically matched kidney transplant patients.

The company takes blood-forming stem cells and immune cells from the organ donor and infuses them into the patient receiving the donor’s kidney. Introducing the donor’s immune cells into the patient creates a condition called “mixed chimerism” where immune cells from the patient and the donor are able to co-exist. In this way, the patient’s immune system is able to adapt to and tolerate the donor’s kidney, potentially eliminating the need for the immunosuppressive drugs that are normally necessary to prevent transplant rejection.

So how does getting RMAT designation help that? Well, the FDA created the RMAT program to help speed up the development and review of regenerative medicine therapies that can treat, modify, reverse, or cure a serious condition. If MDR-101shows it is both safe and effective RMAT could help it get faster approval for wider use.

In a news release Giovanni Ferrara, President and CEO of Medeor, welcomed the news.

“This important designation underscores the tremendous unmet medical need for alternatives to today’s immunosuppressive therapies for transplantation. We have the potential to help people live longer, healthier lives without the need for high dose and chronic immunosuppression and we thank the FDA for this designation that will assist us progressing as efficiently as possible toward a commercially available product.”

This is the seventh CIRM-supported project that has been granted RMAT designation. The others are jCyte, Lineage, Humacyte, St. Jude’s/UCSF X-linked SCID, Poseida, Capricor

Charting a new course for stem cell research

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

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

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

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

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

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

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

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

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

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

We look forward to seeing you there.
