jCyte Shares Encouraging Update on Clinical Trial for Retinitis Pigmentosa

Stepping out of the darkness into light. That’s how patients are describing their experience after participating in a CIRM-funded clinical trial targeting a rare form of vision loss called retinitis pigmentosa (RP). jCyte, the company conducting the trial, announced 12 month results for its candidate stem cell-based treatment for RP.

RP is a genetic disorder that affects approximately 1 in 40,000 individuals and 1.5 million people globally. It causes the destruction of the light-sensing cells at the back of the eye called photoreceptors. Patients experience symptoms of vision loss starting in their teenage years and eventually become legally blind by middle age. While there is no cure for RP, there is hope that stem cell-based therapies could slow its progression in patients.

jCyte is one of the leaders in developing cell-based therapies for RP. The company, which was founded by UC Irvine scientists led by Dr. Henry Klassen, is testing a product called jCell, which is composed of pluripotent stem cell-derived progenitor cells that develop into photoreceptors. When transplanted into the back of the eye, they are believed to release growth factors that prevent further damage to the surviving cells in the retina. They also can integrate into the patient’s retina and develop into new photoreceptor cells to improve a patient’s vision.

Positive Results

At the Annual Ophthalmology Innovation Summit in November, jCyte announced results from its Phase 1/2a trial, which was a 12-month study testing two different doses of transplanted cells in 28 patients. The company reported a “favorable safety profile and indications of potential benefit” to patient vision.

The patients received a single injection of cells in their worst eye and their visual acuity (how well they can see) was then compared between the treated and untreated eye. Patients who received the lower dose of 0.5 million cells were able to see one extra letter on an eye chart with their treated eye compared to their untreated eye while patients that received the larger dose of 3 million cells were able to read 9 more letters. Importantly, none of the patients experienced any significant side effects from the treatment.

According to the company’s news release, “patient feedback was particularly encouraging. Many reported improved vision, including increased sensitivity to light, improved color discrimination and reading ability and better mobility. In addition, 22 of the 28 patients have been treated in their other eye as part of a follow-on extension study.”

One of these patients is Rosie Barrero. She spoke to us earlier this year about how the jCyte trial has not only improved her vision but has also given her hope. You can watch her video below.

Next Steps

These results suggest that the jCell therapy is safe (at least at the one year mark) to use in patients and that larger doses of jCell are more effective at improving vision in patients. jCyte CEO, Paul Bresge commented on the trial’s positive results:

Paul Bresge

“We are very encouraged by these results. Currently, there are no effective therapies to offer patients with RP. We are moving forward as quickly as possible to remedy that. The feedback we’ve received from trial participants has been remarkable. We look forward to moving through the regulatory process and bringing this easily-administered potential therapy to patients worldwide.”

Bresge and his company will be able to navigate jCell through the regulatory process more smoothly with the product’s recent Regenerative Medicine Advanced Therapy (RMAT) designation from the US Food and Drug Administration (FDA). The FDA grants RMAT to regenerative medicine therapies for serious diseases that have shown promise in early-stage clinical trials. The designation allows therapies to receive expedited review as they navigate their way towards commercialization.

jCyte is now evaluating the safety and efficacy of jCell in a Phase2b trial in a larger group of up to 85 patients. CIRM is also funding this trial and you can read more about it on our website.

A Patient Advocate’s Personal Manifesto

Janni and Obama

President Obama and Janni Lehrer-Stein

Janni Lehrer-Stein was just 26 when she was diagnosed with a degenerative eye disease and told she was going to be blind within six months. The doctor who gave her the news told her “But don’t worry, people like you are usually hit and killed by a bus long before they go completely blind.”

At the time she was recently married, had just graduated law school and landed her dream job with the government in Washington DC, litigating workplace discrimination. The news about her eyesight stopped her in her tracks.

But not for long. If you ever met Janni you would know that nothing stops her for long.

I was fortunate enough to hear Janni talk at a Foundation Fighting Blindness event in the San Francisco Bay Area last weekend. I was part of a panel discussion on new approaches to treating vision loss, including the research that CIRM is funding.

Janni didn’t talk about stem cells, instead she focused on the importance of the patient advocate voice, community, and their determination. She said one of the most important things anyone battling a life-threatening or life-changing disease or disorder needs to remember is that it’s not about disability, it’s about capability. It’s about what you can do rather than what you cannot.

Janni laid out her “manifesto” for things she says will help you keep that thought uppermost in your mind.

1) Show up. It’s that simple and that important. You have to show up. You have to get educated, you have to learn all you can about your condition so you know what you can do and what you can’t do. You have to share that information with others. You have to be there for others. Don’t just show up for yourself. Show up for others who can’t be there.

2) Share this information. Janni talked about a website called My Retina Tracker which is helping drive research into the causes of retinal diseases like retinitis pigmentosa and macular degeneration, and hopefully will lead to treatments and even cures. She says the more people work together, the more we combine our resources, the more effective we can be.

3) Support the researchers. Janni says while raising awareness is important, raising money is just as important. Without money there can be no research, and without research no treatments or cures. Janni says it doesn’t matter how you do it – a charity walk, a Go Fund me campaign, petitioning your state or federal elected representatives to urge them to fund research – everything counts, every dollar helps.

4) Remember you are part of a wider community. Janni says no one ever won a battle on their own; it takes a lot of people to fight and win the right to be treated equally. And it takes a lot of effort to stop those rights from being rolled back.

Janni hasn’t let losing her sight hold her back. In 2011, she was appointed by President Obama, and confirmed by the U.S. Senate, to the National Council on Disability where she served two terms advising the President and Congress on national disability policy.

Now she has returned home to the San Francisco Bay Area, but she is no less determined to make a difference and no less determined to fight for the rights of patients and patient advocates.

In an article on Medium she shares her feelings about being a patient advocate:

“The America that I so deeply respect is one that embraces, values and respects the contributions of us all. My America includes every one of us, regardless of our gender, race, age or disability. Our America is a place where, regardless of whether we are sighted or blind, we have the same opportunities, for which we are equally considered. Our America includes every one of us who wishes to make the world a more peaceful, responsible, and inclusive environment that is tolerant of all differences and abilities, physical or otherwise. To me, those differences make our lives richer, give our contributions more meaning, and lead to a brighter future for the next generation.”

 

CIRM-Funded Clinical Trials Targeting Brain and Eye Disorders

This blog is part of our Month of CIRM series, which features our Agency’s progress towards achieving our mission to accelerate stem cell treatments to patients with unmet medical needs.

 This week, we’re highlighting CIRM-funded clinical trials to address the growing interest in our rapidly expanding clinical portfolio. Our Agency has funded a total of 40 trials since its inception. 23 of these trials were funded after the launch of our Strategic Plan in 2016, bringing us close to the half way point of our goal to fund 50 new clinical trials by 2020.

Today we are featuring CIRM-funded trials in our neurological and eye disorders portfolio.  CIRM has funded a total of nine trials targeting these disease areas, and seven of these trials are currently active. Check out the infographic below for a list of our currently active trials.

For more details about all CIRM-funded clinical trials, visit our clinical trials page and read our clinical trials brochure which provides brief overviews of each trial.

Throwback Thursday: Progress to a Cure for Diseases of Blindness

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. This month we’re featuring stories about CIRM-funded clinical trials for blindness.

2017 has been an exciting year for two CIRM-funded clinical trials that are testing stem cell-based therapies for diseases of blindness. A company called Regenerative Patch Technologies (RPT) is transplanting a sheet of embryonic stem cell-derived retinal support cells into patients with the dry form of age-related macular degeneration, a disease that degrades the eye’s macula, the center of the retina that controls central vision. The other trial, sponsored by a company called jCyte, is using human retinal progenitor cells to treat retinitis pigmentosa, a rare genetic disease that destroys the light-sensing cells in the retina, causing tunnel vision and eventually blindness.

 

Both trials are in the early stages, testing the safety of their respective stem cell therapies. But the teams are hopeful that these treatments will stop the progression of or even restore some form of vision in patients. In the past few months, both RPT and jCyte have shared exciting news about the progress of these trials which are detailed below.

Macular Degeneration Trial Gets a New Investor

In April, RPT announced that they have a new funding partner to further develop their stem cell therapy for age-related macular degeneration (AMD). They are partnering with Japan’s Santen Pharmaceutical Company, which specializes in developing ophthalmology or eye therapies.

AMD is the leading cause of blindness in elderly people and is projected to affect almost 200 million people worldwide by 2020. There is no cure or treatment that can restore vision in AMD patients, but stem cell transplants offer a potential therapeutic option.

RPT believes that their newfound partnership with Santen will accelerate the development of their stem cell therapy and ultimately fulfill an unmet medical need. RPT’s co-founder, Dr. Dennis Clegg, commented in a CIRM news release, “the ability to partner with a global leader in ophthalmology like Santen is very exciting. Such a strong partnership will greatly accelerate RPT’s ability to develop our product safely and effectively.”

This promising relationship highlights CIRM’s efforts to partner our clinical programs with outside investors to boost their chance of success. It also shows confidence in the future success of RPT’s stem cell-based therapy for AMD.

Retinitis Pigmentosa Trial Advances to Phase 2 and Receives RMAT Status

In May, the US Food and Drug Administration (FDA) approved jCyte’s RP trial for Regenerative Medicine Advanced Therapy (RMAT) status, which could pave the way for accelerated approval of this stem cell therapy for patients with RP.

RMAT is a new status established under the 21st Century Cures Act – a law enacted by Congress in December of 2016 to address the need for a more efficient regulatory approval process for stem cell therapies that can treat serious or life-threatening diseases. Trial sponsors of RMAT designated therapies can meet with the FDA earlier in the trial process and are eligible for priority review and accelerated approval.

jCyte’s RMAT status is well deserved. Their Phase 1 trial was successful, proving the treatment was safe and well-tolerated in patients. More importantly, some of the patients revealed that their sight has improved following their stem cell transplant. We’ve shared the inspiring stories of two patients, Rosie Barrero and Kristin Macdonald, previously on the Stem Cellar.

Rosie Barrero

Kristin MacDonald

Both Rosie and Kristin were enrolled in the Phase 1 trial and received an injection of retinal progenitor cells in a single eye. Rosie said that she went from complete darkness to being able to see shapes, colors, and the faces of her family and friends. Kristin was the first patient treated in jCyte’s trial, and she said she is now more sensitive to light and can see shapes well enough to put on her own makeup.

Encouraged by these positive results, jCyte launched its Phase 2 trial in April with funding from CIRM. They will test the same stem cell therapy in a larger group of 70 patients and monitor their progress over the next year.

Progress to a Cure for Blindness

We know very well that scientific progress takes time, and unfortunately we don’t know when there will be a cure for blindness. However, with the advances that these two CIRM-funded trials have made in the past year, our confidence that these stem cell treatments will one day benefit patients with RP and AMD is growing.

I’ll leave you with an inspiring video of Rosie Barrero about her experience with RP and how participating in jCytes trial has changed her life. Her story is an important reminder of why CIRM exists and why supporting stem cell research in particular, and research in general, is vital for the future health of patients.

jCyte gets FDA go-ahead for Fast Track review process of Retinitis Pigmentosa stem cell therapy

21 century cures

When the US Congress approved, and President Obama signed into law, the 21st Century Cures Act last year there was guarded optimism that this would help create a more efficient and streamlined, but no less safe, approval process for the most promising stem cell therapies.

Even so many people took a wait and see approach, wanting a sign that the Food and Drug Administration (FDA) would follow the recommendations of the Act rather than just pay lip service to it.

This week we saw encouraging signs that the FDA is serious when it granted Regenerative Medicine Advanced Therapy (RMAT) status to the CIRM-funded jCyte clinical trial for a rare form of blindness. This is a big deal because RMAT seeks to accelerate approval for stem cell therapies that demonstrate they can help patients with unmet medical needs.

klassen

jCyte co-founder Dr. Henry Klassen

jCyte’s work is targeting retinitis pigmentosa (RP), a genetic disease that slowly destroys the cells in the retina, the part of the eye that converts light into electrical signals which the brain then interprets as vision. At first people with RP lose their night and peripheral vision, then the cells that help us see faces and distinguish colors are damaged. RP usually strikes people in their teens and, by the time they are 40, many people are legally blind.

jCyte’s jCell therapy uses what are called retinal progenitor cells, injected into the eye, which then release protective factors to help repair and rescue diseased retinal cells. The hope is this will stop the disease’s progression and even restore some vision to people with RP.

Dr. Henry Klassen, jCyte’s co-founder and a professor at UC Irvine, was understandably delighted by the designation. In a news release, he said:

“This is uplifting news for patients with RP. At this point, there are no therapies that can help them avoid blindness. We look forward to working with the FDA to speed up the clinical development of jCell.”

FDA

On the FDA’s blog – yes they do have one – it says researchers:

“May obtain the RMAT designation for their drug product if the drug is intended to treat serious or life-threatening diseases or conditions and if there is preliminary clinical evidence indicating that the drug has the potential to address unmet medical needs for that disease or condition. Sponsors of RMAT-designated products are eligible for increased and earlier interactions with the FDA, similar to those interactions available to sponsors of breakthrough-designated therapies. In addition, they may be eligible for priority review and accelerated approval.”

Paul Bresge

jCyte CEO Paul Bresge

jCyte is one of the first to get this designation, a clear testimony to the quality of the work done by Dr. Klassen and his team. jCyte CEO Paul Bresge says it may help speed up their ability to get this treatment to patients.

 

“We are gratified by the FDA’s interest in the therapeutic potential of jCell and greatly appreciate their decision to provide extra support. We are seeing a lot of momentum with this therapy. Because it is well-tolerated and easy to administer, progress has been rapid. I feel a growing sense of excitement among patients and clinicians. We look forward to getting this critical therapy over the finish line as quickly as possible.”

Regular readers of this blog will already be familiar with the story of Rosie Barrero, one of the first group of people with RP who got the jCell therapy. Rosie says it has helped restore some vision to the point where she is now able to read notes she wrote ten years ago, distinguish colors and, best of all, see the faces of her children.

RMAT is no guarantee the therapy will be successful. But if the treatment continues to show promise, and is safe, it could mean faster access to a potentially life-changing therapy, one that could ultimately rescue many people from a lifetime of living in the dark.

 

 

jCyte starts second phase of stem cell clinical trial targeting vision loss

retinitis pigmentosas_1

How retinitis pigmentosa destroys vision

Studies show that Americans fear losing their vision more than any other sense, such as hearing or speech, and almost as much as they fear cancer, Alzheimer’s and HIV/AIDS. That’s not too surprising. Our eyes are our connection to the world around us. Sever that connection, and the world is a very different place.

For people with retinitis pigmentosa (RP), the leading cause of inherited blindness in the world, that connection is slowly destroyed over many years. The disease eats away at the cells in the eye that sense light, so the world of people with RP steadily becomes darker and darker, until the light goes out completely. It often strikes people in their teens, and many are blind by the time they are 40.

There are no treatments. No cures. At least not yet. But now there is a glimmer of hope as a new clinical trial using stem cells – and funded by CIRM – gets underway.

klassenWe have talked about this project before. It’s run by UC Irvine’s Dr. Henry Klassen and his team at jCyte. In the first phase of their clinical trial they tested their treatment on a small group of patients with RP, to try and ensure that their approach was safe. It was. But it was a lot more than that. For people like Rosie Barrero, the treatment seems to have helped restore some of their vision. You can hear Rosie talk about that in our recent video.

Now the same treatment that helped Rosie, is going to be tested in a much larger group of people, as jCyte starts recruiting 70 patients for this new study.

In a news release announcing the start of the Phase 2 trial, Henry Klassen said this was an exciting moment:

“We are encouraged by the therapy’s excellent safety track record in early trials and hope to build on those results. Right now, there are no effective treatments for retinitis pigmentosa. People must find ways to adapt to their vision loss. With CIRM’s support, we hope to change that.”

The treatment involves using retinal progenitor cells, the kind destroyed by the disease. These are injected into the back of the eye where they release factors which the researchers hope will help rescue some of the diseased cells and regenerate some replacement ones.

Paul Bresge, CEO of jCyte, says one of the lovely things about this approach, is its simplicity:

“Because no surgery is required, the therapy can be easily administered. The entire procedure takes minutes.”

Not everyone will get the retinal progenitor cells, at least not to begin with. One group of patients will get an injection of the cells into their worst-sighted eye. The other group will get a sham injection with no cells. This will allow researchers to compare the two groups and determine if any improvements in vision are due to the treatment or a placebo effect.

The good news is that after one year of follow-up, the group that got the sham injection will also be able to get an injection of the real cells, so that if the therapy is effective they too may be able to benefit from it.

Rosie BarreroWhen we talked to Rosie Barrero about the impact the treatment had on her, she said it was like watching the world slowly come into focus after years of not being able to see anything.

“My dream was to see my kids. I always saw them with my heart, but now I can see them with my eyes. Seeing their faces, it’s truly a miracle.”

We are hoping this Phase 2 clinical trial gives others a chance to experience similar miracles.

CIRM Alpha Clinics Network charts a new course for delivering stem cell treatments

Sometimes it feels like finding a cure is the easy part; getting it past all the hurdles it must overcome to be able to reach patients is just as big a challenge. Fortunately, a lot of rather brilliant minds are hard at work to find the most effective ways of doing just that.

Last week, at the grandly titled Second Annual Symposium of the CIRM Alpha Stem Cell Clinics Network, some of those minds gathered to talk about the issues around bringing stem cell therapies to the people who need them, the patients.

The goal of the Alpha Clinics Network is to accelerate the development and delivery of stem cell treatments to patients. In doing that one of the big issues that has to be addressed is cost; how much do you charge for a treatment that can change someone’s life, even save their life? For example, medications that can cure Hepatitis C cost more than $80,000. So how much would a treatment cost that can cure a disease like Severe Combined Immunodeficiency (SCID)? CIRM-funded researchers have come up with a cure for SCID, but this is a rare disease that affects between 40 – 100 newborns every year, so the huge cost of developing this would fall on a small number of patients.

The same approach that is curing SCID could also lead to a cure for sickle cell disease, something that affects around 100,000 people in the US, most of them African Americans. Because we are adding more people to the pool that can be treated by a therapy does that mean the cost of the treatment should go down, or will it stay the same to increase profits?

Jennifer Malin, United Healthcare

Jennifer Malin from United Healthcare did a terrific job of walking us through the questions that have to be answered when trying to decide how much to charge for a drug. She also explored the thorny issue of who should pay; patients, insurance companies, the state? As she pointed out, it’s no use having a cure if it’s priced so high that no one can afford it.

Joseph Alvarnas, the Director of Value-based Analytics at City of Hope – where the conference was held – said that in every decision we make about stem cell therapies we “must be mindful of economic reality and inequality” to ensure that these treatments are available to all, and not just the rich.

“Remember, the decisions we make now will influence not just the lives of those with us today but also the lives of all those to come.”

Of course long before you even have to face the question of who will pay for it, you must have a treatment to pay for. Getting a therapy through the regulatory process is challenging at the best of times. Add to that the fact that many researchers have little experience navigating those tricky waters and you can understand why it takes more than eight years on average for a cell therapy to go from a good idea to a clinical trial (in contrast it takes just 3.2 years for a more traditional medication to get into a clinical trial).

Sunil Kadim, QuintilesIMS

Sunil Kadam from QuintilesIMS talked about the skills and expertise needed to navigate the regulatory pathway. QuintilesIMS partners with CIRM to run the Stem Cell Center, which helps researchers apply for and then run a clinical trial, providing the guidance that is essential to keeping even the most promising research on track.

But, as always, at the heart of every conference, are the patients and patient advocates. They provided the inspiration and a powerful reminder of why we all do what we do; to help find treatments and cures for patients in need.

The Alpha Clinic Network is only a few years old but is already running 35 different clinical trials involving hundreds of patients. The goal of the conference was to discuss lessons learned and share best practices so that number of trials and patients can continue to increase.

The CIRM Board is also doing its part to pick up the pace, approving funding for up to two more Alpha Clinic sites.  The deadline to apply to be one of our new Alpha Clinics sites is May 15th, and you can learn more about how to apply on our funding page.

Since joining CIRM I have been to many conferences but this was, in my opinion, the best one I have ever intended. It brought together people from every part of the field to give the most complete vision for where we are, and where we are headed. The talks were engaging, and inspiring.

Kristin Macdonald was left legally blind by retinitis pigmentosa, a rare vision-destroying disease. A few years ago she became the first person to be treated with a CIRM-funded therapy aimed to restoring some vision. She says it is helping, that for years she lived in a world of darkness and, while she still can’t see clearly, now she can see light. She says coming out of the darkness and into the light has changed her world.

Kristin Macdonald

In the years to come the Alpha Clinics Network hopes to be able to do the same, and much more, for many more people in need.

Raising awareness about Rare Disease Day

rare-disease-day-logo

One of the goals we set ourselves at CIRM in our 2016 Strategic Plan was to fund 50 new clinical trials over the next five years, including ten rare or orphan diseases. Since then we have funded 13 new clinical trials including four targeting rare diseases (retinitis pigmentosa, severe combined immunodeficiency, ALS or Lou Gehrig’s disease, and Duchenne’s Muscular Dystrophy). It’s a good start but clearly, with almost 7,000 rare diseases, this is just the tip of the iceberg. There is still so much work to do.

And all around the world people are doing that work. Today we have asked Emily Walsh, the Community Outreach Director at the Mesothelioma Cancer Alliance,  to write about the efforts underway to raise awareness about rare diseases, and to raise funds for research to develop new treatments for them.

“February 28th marks the annual worldwide event for Rare Disease Day. This is a day dedicated to raising awareness for rare diseases that affect people all over the world. The campaign works to target the general public as well as policy makers in hopes of bringing attention to diseases that receive little attention and funding. For the year 2017 it was decided that the focus would fall on “research,” with the slogan, “With research, possibilities are limitless.”

Getting involved for Rare Disease Day means taking this message and spreading it far and wide. Awareness for rare diseases is extremely important, especially among researchers, universities, students, companies, policy makers, and clinicians. It has long been known that the best advocates for rare diseases are the patients themselves. They use their specific perspectives to raise their voice, share their story, and shed light on the areas where additional funding and research are most necessary.

To see how you can help support the Rare Disease Day efforts this year, click here.

Groups like the Mesothelioma Cancer Alliance and the Mesothelioma Group are adding their voices to the cause to raise awareness about mesothelioma cancer, a rare form of cancer caused by exposure and inhalation of airborne asbestos fibers

Rare diseases affect 300 million people worldwide, but only 5% of them have an FDA approved treatment or cure. Malignant mesothelioma is among the 95 percent that doesn’t have a treatment or cure.

Asbestos has been used throughout history in building materials because of its fire retardant properties. Having a home with asbestos insulation, ceiling tiles, and roof shingles meant that the house was safer. However, it was found that once asbestos crumbled and became powder-like, the tiny fibers could become airborne and be inhaled and lodge themselves in lung tissue causing mesothelioma. The late stage discovery of mesothelioma is often what causes it to have such a high mortality rate. Symptoms can have a very sudden onset, even though the person may have been exposed decades prior.

Right now, treatment for mesothelioma includes the usual combination of chemotherapy, radiation, and surgery, but researchers are looking at other approaches to see if they can be more effective or can help in conjunction with the standard methods. For example one drug, Defactinib, has shown some promise in inhibiting the growth and spread of cancer stem cells – these are stem cells that can evade chemotherapy and cause patients to relapse.”

Some people might ask why spend limited resources on something that affects so few people. But the lessons we learn in developing treatments for a rare disease can often lead us to treatments for diseases that affect many millions of people.

But numbers aside, there is no hierarchy of need, no scale to say the suffering of people with Huntington’s disease is any greater or less than that of people with Alzheimer’s. We are not in the business of making value judgements about who has the greatest need. We are in the business of accelerating treatments to patients with unmet medical needs. And those suffering from rare disease are very clearly  people in need.

California’s stem cell agency rounds up the year with two more big hits

icoc_dec2016-17

CIRM Board meeting with  Jake Javier, CIRM Chair Jonathan Thomas, Vice Chair Sen. Art Torres (Ret.) and President/CEO Randy Mills

It’s traditional to end the year with a look back at what you hoped to accomplish and an assessment of what you did. By that standard 2016 has been a pretty good year for us at CIRM.

Yesterday our governing Board approved funding for two new clinical trials, one to help kidney transplant patients, the second to help people battling a disease that destroys vision. By itself that is a no small achievement. Anytime you can support potentially transformative research you are helping advance the field. But getting these two clinical trials over the start line means that CIRM has also met one of its big goals for the year; funding ten new clinical trials.

If you had asked us back in the summer, when we had funded only two clinical trials in 2016, we would have said that the chances of us reaching ten trials by the end of the year were about as good as a real estate developer winning the White House. And yet……..

Helping kidney transplant recipients

The Board awarded $6.65 million to researchers at Stanford University who are using a deceptively simple approach to help people who get a kidney transplant. Currently people who get a transplant have to take anti-rejection medications for the rest of their life to prevent their body rejecting the new organ. These powerful immunosuppressive medications are essential but also come with a cost; they increase the risk of cancer, infection and heart disease.

icoc_dec2016-3

CIRM President/CEO Randy Mills addresses the CIRM Board

The Stanford team will see if it can help transplant patients bypass the need for those drugs by injecting blood stem cells and T cells (which play an important role in the immune system) from the kidney donor into the kidney recipient. The hope is by using cells from the donor, you can help the recipient’s body more readily adjust to the new organ and reduce the likelihood the body’s immune system will attack it.

This would be no small feat. Every year around 17,000 kidney transplants take place in the US, and many people who get a donor kidney experience fevers, infections and other side effects as a result of taking the anti-rejection medications. This clinical trial is a potentially transformative approach that could help protect the integrity of the transplanted organ, and improve the quality of life for the kidney recipient.

Fighting blindness

The second trial approved for funding is one we are already very familiar with; Dr. Henry Klassen and jCyte’s work in treating retinitis pigmentosa (RP). This is a devastating disease that typically strikes before age 30 and slowly destroys a person’s vision. We’ve blogged about it here and here.

Dr. Klassen, a researcher at UC Irvine, has developed a method of injecting what are called retinal progenitor cells into the back of the eye. The hope is that these cells will repair and replace the cells damaged by RP. In a CIRM-funded Phase 1 clinical trial the method proved safe with no serious side effects, and some of the patients also reported improvements in their vision. This raised hopes that a Phase 2 clinical trial using a larger number of cells in a larger number of patients could really see if this therapy is as promising as we hope. The Board approved almost $8.3 million to support that work.

Seeing is believing

How promising? Well, I recently talked to Rosie Barrero, who took part in the first phase clinical trial. She told me that she was surprised how quickly she started to notice improvements in her vision:

“There’s more definition, more colors. I am seeing colors I haven’t seen in years. We have different cups in our house but I couldn’t really make out the different colors. One morning I woke up and realized ‘Oh my gosh, one of them is purple and one blue’. I was by myself, in tears, and it felt amazing, unbelievable.”

Amazing was a phrase that came up a lot yesterday when we introduced four people to our Board. Each of the four had taken part in a stem cell clinical trial that changed their lives, even saved their lives. It was a very emotional scene as they got a chance to thank the group that made those trials, those treatments possible.

We’ll have more on that in a future blog.

 

 

 

 

How stem cells are helping change the face of medicine, one pioneering patient at a time

One of the many great pleasures of my job is that I get to meet so many amazing people. I get to know the researchers who are changing the face of medicine, but even more extraordinary are the people who are helping them do it, the patients.

Attacking Cancer

Karl

Karl Trede

It’s humbling to meet people like Karl Trede from San Jose, California. Karl is a quiet, witty, unassuming man who when the need arose didn’t hesitate to put himself forward as a medical pioneer.

Diagnosed with throat cancer in 2006, Karl underwent surgery to remove the tumor. Several years later, his doctors told him it had returned, only this time it had spread to his lungs. They told him there was no effective treatment. But there was something else.

“One day the doctor said we have a new trial we’re going to start, would you be interested? I said “sure”. I don’t believe I knew at the time that I was going to be the first one, but I thought I’d give it a whirl.”

Karl was Patient #1 in a clinical trial at Stanford University that was using a novel approach to attack cancer stem cells, which have the ability to evade standard anti-cancer treatments and cause the tumors to regrow. The team identified a protein, called CD47, that sits on the surface of cancer stem cells and helps them evade being gobbled up and destroyed by the patient’s own immune system. They dubbed CD47 the “don’t eat me” signal and created an antibody therapy they hoped would block the signal, leaving the cancer and the cancer stem cells open to attack by the immune system.

The team did pre-clinical testing of the therapy, using mice to see if it was safe. Everything looked hopeful. Even so, this was still the first time it was being tested in a human. Karl said that didn’t bother him.

“It was an experience for me, it was eye opening. I wasn’t real concerned about being the first in a trial never tested in people before. I said we know that there’s no effective treatment for this cancer, it’s not likely but it’s possible that this could be the one and if nothing else, if it doesn’t do anything for me hopefully it does something so they learn for others.”

It’s that kind of selflessness that is typical of so many people who volunteer for clinical trials, particularly Phase 1 trials, where a treatment is often being tried in people for the first time ever. In these trials, the goal is to make sure the approach is safe, so patients are given a relatively small dose of the therapy (cells or drugs) and told ahead of time it may not do any good. They’re also told that there could be some side effects, potentially serious, even life-threatening ones. Still, they don’t hesitate.

Improving vision

Rosie Barrero certainly didn’t hesitate when she got a chance to be part of a clinical trial testing the use of stem cells to help people with retinitis pigmentosa, a rare progressive disease that destroys a person’s vision and ultimately leaves them blind.

“I was extremely excited about the clinical trial. I didn’t have any fear or trepidation about it, I would have been happy being #1, and I was #6 and that was fine with me.”

 

Rosie had what are called retinal progenitor cells injected into her eye, part of a treatment developed by Dr. Henry Klassen at the University of California, Irvine. The hope was that those cells would help repair and perhaps even replace the light-sensing cells damaged by the disease.

Following the stem cell treatment, gradually Rosie noticed a difference. It was small things at first, like being able to make out the colors of cups in her kitchen cupboard, or how many trash cans were outside their house.

“I didn’t expect to see so much, I thought it would be minor, and it is minor on paper but it is hard to describe the improvement. It’s visible, it’s visible improvement.”

These are the moments that researchers like Henry Klassen live for, and have worked so tirelessly for. These are the moments that everyone at CIRM dreams of, when the work we have championed, supported and funded shows it is working, shows it is changing people’s lives.

One year ago this month our governing Board approved a new Strategic Plan, a detailed roadmap of where we want to go in the coming years. The plan laid out some pretty ambitious goals, such as funding 50 new clinical trials in the next 5 years, and at our Board meeting next week we’ll report on how well we are doing in terms of hitting those targets.

People like Karl and Rosie help motivate us to keep trying, to keep working as hard as we can, to achieve those goals. And if ever we have a tough day, we just have to remind ourselves of what Rosie said when she realized she could once again see her children.

“Seeing their faces. It’s pretty incredible. I always saw them with my heart so I just adore them, but now I can see them with my eye.”
