Developing a non-toxic approach to bone-crushing cancers

When cancer spreads to the bone the results can be devastating

Battling cancer is always a balancing act. The methods we use – surgery, chemotherapy and radiation – can help remove the tumors but they often come at a price to the patient. In cases where the cancer has spread to the bone the treatments have a limited impact on the disease, but their toxicity can cause devastating problems for the patient. Now, in a CIRM-supported study, researchers at UC Irvine (UCI) have developed a method they say may be able to change that.

Bone metastasis – where cancer starts in one part of the body, say the breast, but spreads to the bones – is one of the most common complications of cancer. It can often result in severe pain, increased risk of fractures and compression of the spine. Tackling them is difficult because some cancer cells can alter the environment around bone, accelerating the destruction of healthy bone cells, and that in turn creates growth factors that stimulate the growth of the cancer. It is a vicious cycle where one problem fuels the other.

Now researchers at UCI have developed a method where they combine engineered mesenchymal stem cells (taken from the bone marrow) with targeting agents. These act like a drug delivery device, offloading different agents that simultaneously attack the cancer but protect the bone.

In a news release Weian Zhao, lead author of the study, said:

“What’s powerful about this strategy is that we deliver a combination of both anti-tumor and anti-bone resorption agents so we can effectively block the vicious circle between cancers and their bone niche. This is a safe and almost nontoxic treatment compared to chemotherapy, which often leaves patients with lifelong issues.”

The research, published in the journal EBioMedicine, has already been shown to be effective in mice. Next, they hope to be able to do the safety tests to enable them to apply to the Food and Drug Administration for permission to test it in people.

The team say if this approach proves effective it might also be used to help treat other bone-related diseases such as osteoporosis and multiple myeloma.

Mending Stem Cells: The Past, Present & Future of Regenerative Medicine

UCSF’s Mission Bay Campus

For years we have talked about the “promise” and the “potential” of stem cells to cure patients. But more and more we are seeing firsthand how stem cells can change a patient’s life, even saving it in some cases. That’s the theme of the 4th Annual CIRM Alpha Stem Cell Clinics Network Symposium.

It’s not your usual symposium because this brings together all the key players in the field – the scientists who do the research, the nurses and doctors who deliver the therapies, and the patients who get or need those therapies. And, of course, we’ll be there; because without CIRM’s funding to support that research and therapies none of this happens.

We are going to look at some of the exciting progress being made, and what is on the horizon. But along the way we’ll also tackle many of the questions that people pose to us every day. Questions such as:

  • How can you distinguish between a good clinical trial offering legitimate treatments vs a stem cell clinic offering sham treatments?
  • What about the Right to Try, can’t I just demand I get access to stem cell therapies?
  • How do I sign up for a clinical trial, and how much will it cost me?
  • What is the experience of patients that have participated in a stem cell clinical trial?

World class researchers will also talk about the real possibility of curing diseases like sickle cell disease on a national scale, which affect around 100,000 Americans, mostly African Americans and Hispanics. They’ll discuss the use of gene editing to battle hereditary diseases like Huntington’s. And they’ll highlight how they can engineer a patient’s own immune system cells to battle deadly cancers.

So, join us for what promises to be a fascinating day. It’s the cutting edge of science. And it’s all FREE.

Here’s where you can go to find out more information and to sign up for the event.

Mending Stem Cells: The Past, Present and Future of Regenerative Medicine

To Mend: (verb used with object) to make (something broken, worn, torn or otherwise damaged) whole, sound or usable by repairing.

It’s remarkable to believe, but today doctors literally have the tools to repair damaged cells. These tools are being used to treat people with diseases that were once incurable. The field of regenerative medicine has made tremendous progress in the last 15 years, but how did these tools come about and what is the experience of patients being treated with them?

These questions, and hopefully yours too, are going to be answered at the fourth annual CIRM Alpha Stem Cell Clinics Symposium on April 18, 2019 at the University of California at San Francisco.

UCSF Mission Bay Campus

The symposium is free, and the program is designed with patients and the public in mind, so don’t be shy and put your scientific thinking caps on! A complete agenda may be found here

Perhaps one of the most remarkable discoveries in the past decade are new tools that enable doctors to “edit” or correct a patient’s own DNA. DNA correction tools came about because of a remarkable string of scientific breakthroughs. The symposium will dive into this history and discuss  how these tools are being used today to treat patients.

One specific example of the promise that DNA editing holds is for those with sickle cell disease (SCD), a condition where patients’ blood forming stem cells contain a genetic error that causes the disease. The symposium will describe how the CIRM Alpha Stem Cell Clinics Network, a series of medical centers across California whose focus is on stem cell clinical trials, are supporting work aimed at mending blood cells to cure debilitating diseases like SCD.

Doctors, nurses and patients involved with these trials will be telling their stories and describing their experiences. One important focus will be how Alpha Clinic teams are partnering with community members to ensure that patients, interested in new treatments, are informed about the availability of clinical trials and receive sufficient information to make the best treatment choices.

The fourth annual CIRM Alpha Stem Cell Clinics Symposium is an opportunity for patients, their families and the public to meet the pioneers who are literally mending a patients own stem cells to cure their disease.

Rare Disease Gets Big Boost from California’s Stem Cell Agency

UC Irvine’s Dr. Leslie Thompson and patient advocate Frances Saldana after the CIRM Board vote to approve funding for Huntington’s disease

If you were looking for a poster child for an unmet medical need Huntington’s disease (HD) would be high on the list. It’s a devastating disease that attacks the brain, steadily destroying the ability to control body movement and speech. It impairs thinking and often leads to dementia. It’s always fatal and there are no treatments that can stop or reverse the course of the disease. Today the Board of the California Institute for Regenerative Medicine (CIRM) voted to support a project that shows promise in changing that.

The Board voted to approve $6 million to enable Dr. Leslie Thompson and her team at the University of California, Irvine to do the late stage testing needed to apply to the US Food and Drug Administration for permission to start a clinical trial in people. The therapy involves transplanting stem cells that have been turned into neural stem cells which secrete a molecule called brain-derived neurotrophic factor (BDNF), which has been shown to promote the growth and improve the function of brain cells. The goal is to slow down the progression of this debilitating disease.

“Huntington’s disease affects around 30,000 people in the US and children born to parents with HD have a 50/50 chance of getting the disease themselves,” says Dr. Maria T. Millan, the President and CEO of CIRM. “We have supported Dr. Thompson’s work for a number of years, reflecting our commitment to helping the best science advance, and are hopeful today’s vote will take it a crucial step closer to a clinical trial.”

Another project supported by CIRM at an earlier stage of research was also given funding for a clinical trial.

The Board approved almost $12 million to support a clinical trial to help people undergoing a kidney transplant. Right now, there are around 100,000 people in the US waiting to get a kidney transplant. Even those fortunate enough to get one face a lifetime on immunosuppressive drugs to stop the body rejecting the new organ, drugs that increase the risk for infection, heart disease and diabetes.  

Dr. Everett Meyer, and his team at Stanford University, will use a combination of healthy donor stem cells and the patient’s own regulatory T cells (Tregs), to train the patient’s immune system to accept the transplanted kidney and eliminate the need for immunosuppressive drugs.

The initial group targeted in this clinical trial are people with what are called HLA-mismatched kidneys. This is where the donor and recipient do not share the same human leukocyte antigens (HLAs), proteins located on the surface of immune cells and other cells in the body. Around 50 percent of patients with HLA-mismatched transplants experience rejection of the organ.

In his application Dr. Meyer said they have a simple goal: “The goal is “one kidney for life” off drugs with safety for all patients. The overall health status of patients off immunosuppressive drugs will improve due to reduction in side effects associated with these drugs, and due to reduced graft loss afforded by tolerance induction that will prevent chronic rejection.”

71 for Proposition 71

Proposition 71 is the state ballot initiative that created California’s Stem Cell Agency. This month, the Agency reached another milestone when the 71st clinical trial was initiated in the CIRM Alpha Stem Cell Clinics (ASCC) Network. The ASCC Network deploys specialized teams of doctors, nurses and laboratory technicians to conduct stem cell clinical trials at leading California Medical Centers.

These teams work with academic and industry partners to support patient-centered for over 40 distinct diseases including:

  • Amyotrophic Lateral Sclerosis (ALS)
  • Brain Injury & Stroke
  • Cancer at Multiple Sites
  • Diabetes Type 1
  • Eye Disease / Blindness Heart Failure
  • HIV / AIDS
  • Kidney Failure
  • Severe Combined Immunodeficiency (SCID)
  • Sickle Cell Anemia
  • Spinal Cord Injury

These clinical trials have treated over 400 patients and counting. The Alpha Stem Cell Clinics are part of CIRM’s Strategic Infrastructure. The Strategic Infrastructure program which was developed to support the growth of stem cell / regenerative medicine in California. A comprehensive update of CIRM’s Infrastructure Program was provided to our Board, the ICOC.

CIRM’s infrastructure catalyzes stem cell / regenerative medicine by providing resources to all qualified researchers and organizations requiring specialized expertise. For example, the Alpha Clinics Network is supporting clinical trials from around the world.

Many of these trials are sponsored by commercial companies that have no CIRM funding. To date, the ASCC Network has over $27 million in contracts with outside sponsors. These contracts serve to leverage CIRMs investment and provide the Network’s medical centers with a diverse portfolio of clinical trials to address patients’’ unmet medical needs.

Alpha Clinics – Key Performance Metrics

  • 70+ Clinical Trials
  • 400+ Patients Treated
  • 40+ Disease Indications
  • Over $27 million in contracts with commercial sponsors

The CIRM Alpha Stem Cell Clinics and broader Infrastructure Programs are supporting stem cell research and regenerative medicine at every level, from laboratory research to product manufacturing to delivery to patients. This infrastructure has emerged to make California the world leader in regenerative medicine. It all started because California’s residents supported a ballot measure and today we have 71 clinical trials for 71.

 

 

Newest member of CIRM Board is a guitar-playing, German Shepherd dog loving, molecular geneticist

Sandmeyer, Suzanne01

Suzanne Sandmeyer, Ph.D.

The newest member of the CIRM Board is a researcher who wasn’t always sure she would have a career as a scientist. Suzanne Sandmeyer, PhD, says at the start of her career she had a lot of doubts.

“During my postdoc, I was developing the impression I would struggle to survive in my career as a scientist. I had a female mentor at the time and I shared this idea with her.  She told me that was ridiculous: I was not going to starve, and I believed her. Turns out, she was right. Today, I enjoy the independence that comes with academia.”

We’re delighted she changed her mind. Dr. Sandmeyer, is now the Vice Dean for Research at the University of California at Irvine (UCI) School of Medicine, and has been appointed to CIRM’s Board.

She was recommended for the position by UCI Chancellor Howard Gillman who called her “an outstanding researcher who has contributed significantly to the field of molecular genetics.”

Dr. Sandmeyer said she was honored to be chosen.

“It is a privilege to be involved in this new era of stem cell research and clinical trials. We have only just begun to understand the potential of our discoveries and the impact we can have on human health by advancing stem cell therapies.”

Jonathan Thomas, Ph.D., J.D., the Chair of the CIRM Board, welcomed the appointment saying:

“Dr. Sandmeyer will be a great addition to the Board.  She has a distinguished career, not just as a highly regarded scientist but also as a leader in helping UC Irvine become the great research institution it is today.”

Dr. Sandmeyer’s career as a scientist had an early beginning.

“My Dad was an engineer, so science always seemed like a very natural thing to pursue. Growing up I liked to be outdoors and loved the diversity of living things, so I eventually gravitated toward biology.”

That sense of curiosity and love of biology has helped her build a bustling and productive research lab at UC Irvine. Her research focuses on molecular genetics and biochemistry of retrovirus-like elements called retrotransposons (which make up almost half the human genome but are not well understood) and metabolic engineering in yeast.  Although she has had amazing success in academia, she was not always sure that this would be her path.

As a member of the CIRM Board, Dr. Sandmeyer will provide important insight and perspective into advancing stem cell therapies.

“Our country has one of the most expensive systems of medical care and yet we don’t have the longest-lived population. I want to work toward reducing the burden of medical expenses for people. I am very excited about the potential of stem cells to treat many disorders and the potential for new technologies like CRISPR to further empower that approach.”

When not making important scientific discoveries in the lab, you can find Dr. Sandmeyer pursuing one of her many and varied hobbies.

“I go through phases like everyone. There is never enough time. My favorites are astronomy, bird photography, guitar, biking, kayaking, reading and of course German shepherd dogs.”

 

CIRM invests in stem cell clinical trial targeting lung cancer and promising research into osteoporosis and incontinence

Lung cancer

The five-year survival rate for people diagnosed with the most advanced stage of non-small cell lung cancer (NSCLC) is pretty grim, only between one and 10 percent. To address this devastating condition, the Board of the California Institute for Regenerative Medicine (CIRM) today voted to invest almost $12 million in a team from UCLA that is pioneering a combination therapy for NSCLC.

The team is using the patient’s own immune system where their dendritic cells – key cells in our immune system – are genetically modified to boost their ability to stimulate their native T cells – a type of white blood cell – to destroy cancer cells.  The investigators will combine this cell therapy with the FDA-approved therapy pembrolizumab (better known as Keytruda) a therapeutic that renders cancer cells more susceptible to clearance by the immune system.

“Lung cancer is a leading cause of cancer death for men and women, leading to 150,000 deaths each year and there is clearly a need for new and more effective treatments,” says Maria T. Millan, M.D., the President and CEO of CIRM. “We are pleased to support this program that is exploring a combination immunotherapy with gene modified cell and antibody for one of the most extreme forms of lung cancer.”

Translation Awards

The CIRM Board also approved investing $14.15 million in four projects under its Translation Research Program. The goal of these awards is to support promising stem cell research and help it move out of the laboratory and into clinical trials in people.

Researchers at Stanford were awarded almost $6 million to help develop a treatment for urinary incontinence (UI). Despite being one of the most common indications for surgery in women, one third of elderly women continue to suffer from debilitating urinary incontinence because they are not candidates for surgery or because surgery fails to address their condition.

The Stanford team is developing an approach using the patient’s own cells to create smooth muscle cells that can replace those lost in UI. If this approach is successful, it provides a proof of concept for replacement of smooth muscle cells that could potentially address other conditions in the urinary tract and in the digestive tract.

Max BioPharma Inc. was awarded almost $1.7 million to test a therapy that targets stem cells in the skeleton, creating new bone forming cells and blocking the destruction of bone cells caused by osteoporosis.

In its application the company stressed the benefit this could have for California’s diverse population stating: “Our program has the potential to have a significant positive impact on the lives of patients with osteoporosis, especially in California where its unique demographics make it particularly vulnerable. Latinos are 31% more likely to have osteoporosis than Caucasians, and California has the largest Latino population in the US, accounting for 39% of its population.”

Inspiring Video: UC Irvine Stem Cell Trial Gives Orange County Woman Hope in Her Fight Against ALS

Stephen Hawking

Last week, we lost one of our greatest, most influential scientific minds. Stephen Hawking, a famous British theoretical physicist and author of “A Brief History of Time: From the Big Bang to Black Holes”, passed away at the age of 76.

Hawking lived most of his adult life in a wheelchair because he suffered from amyotrophic lateral sclerosis (ALS). Also known as Lou Gehrig’s disease, ALS causes the degeneration of the nerve cells that control muscle movement.

When Hawking was diagnosed with ALS at the age of 21, he was told he only had three years to live. But Hawking defied the odds and went on to live a life that not only revolutionized our understanding of the cosmos, but also gave hope to other patients suffering from this devastating degenerative disease.

A Story of Hope

Speaking of hope, I’d like to share another story of an Orange County woman name Lisa Wittenberg who was recently diagnosed with ALS. Her story was featured this week on KTLA5 news and is also available on the UC Irvine Health website.

VIDEO: UCI Health stem cell trial helps Orange County woman fight neurodegenerative disease ALS. Click on image to view video in new window.

In this video, Lisa describes how quickly ALS changed her life. She was with her family sledding in the snow last winter, and only a year later, she is in a wheelchair unable to walk. Lisa got emotional when she talked about how painful it is for her to see her 13-year-old son watch her battle with this disease.

But there is hope for Lisa in the form of a stem cell clinical trial at the UC Irvine CIRM Alpha Stem Cell Clinic. Lisa enrolled in the Brainstorm study, a CIRM-funded phase 3 trial that’s testing a mesenchymal stem cell therapy called NurOwn. BrainStorm Cell Therapeutics, the company sponsoring this trial, is isolating mesenchymal stem cells from the patient’s own bone marrow. The stem cells are then cultured in the lab under conditions that convert them into biological factories secreting a variety of neurotrophic factors that help protect the nerve cells damaged by ALS. The modified stem cells are then transplanted back into the patient where they will hopefully slow the progression of the disease.

Dr. Namita Goyal, a neurologist at UC Irvine Health involved in the trial, explained in the KTLA5 video that they are hopeful this treatment will give patients more time, and optimistic that in some cases, it could improve some of their symptoms.

Don’t Give Up the Fight

The most powerful part of Lisa’s story to me was the end when she says,

“I think it’s amazing that I get to fight, but I want everybody to get to fight. Everybody with ALS should get to fight and should have hope.”

Not only is Lisa fighting by being in this ground-breaking trial, she is also participated in the Los Angeles marathon this past weekend, raising money for ALS research.

More patients like Lisa will get the chance to fight as more potential stem cell treatments and drugs enter clinical trials. Videos like the one in this blog are important for raising awareness about available clinical trials like the Brainstorm study, which, by the way, is still looking for more patients to enroll (contact information for this trial can be found on the clinicaltrials.gov website here). CIRM is also funding another stem cell trial for ALS at the Cedars-Sinai Medical Center. You can read more about this trial on our website.

Lisa’s powerful message of fighting ALS and having hope reminds me of one of Stephen Hawking’s most famous quotes, which I’ll leave you with:

“Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the Universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don’t just give up.”

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.

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.
