First patient dosed in clinical trial for a drug-resistant form of epilepsy

Epilepsy seems to have been a problem for people for as long as people have been around. The first recorded mention of it is on a 4000-year-old Akkadian tablet found in Mesopotamia (modern day Iraq). The tablet includes a description of a person with “his neck turning left, hands and feet are tense, and his eyes wide open, and from his mouth froth is flowing without him having any consciousness.”

Despite that long history, effective treatments for epilepsy were a long time coming. It wasn’t till the middle of the 19th century that physicians started using bromides to help people with the condition, but they also came with some nasty side effects, including depression, weakness, fatigue, lethargy, and coma.

Fast forward 150 years or so and we are now, hopefully, entering a new era. This week, Neurona Therapeutics announced they had dosed the first patient in their first-in-human clinical trial formesial temporal lobe epilepsy (MTLE), the most common form of focal epilepsy in adults. The trial specifically targets people who have a drug-resistant form of MTLE.

Neurona has developed a therapy called NRTX-1001, consisting of a specialized type of neuronal or brain cell derived from embryonic stem cells.  These cells are injected into the brain in the area affected by the seizures where they release a neurotransmitter or chemical messenger that will block the signals in the brain causing the epileptic seizures. Pre-clinical testing suggests a single dose of NRTX-1001 may have a long-lasting ability to suppress seizures.

A new approach is very much needed because current therapies for drug-resistant epilepsy are only partially effective and have serious drawbacks. One treatment that can significantly reduce seizure frequency is the removal of the affected part of the brain, however this can cause serious, irreversible damage, such as impacting memory, mood and vision.

CIRM has a vested interest in seeing this therapy succeed. We have invested more than $14 million over four different awards, in helping this research progress from a basic or Discovery level through to the current clinical trial.

In a news release, two key figures in administering the first dose to a patient said this was an important step forward. 

Harish Babu, M.D., Ph.D., assistant professor of neurosurgery at SUNY Upstate Medical University said: “Neurona’s regenerative cell therapy approach has the potential to provide a single-administration, non-destructive alternative for the treatment of drug-resistant focal epilepsy. Currently, people with mesial temporal lobe epilepsy who are not responsive to anti-seizure medications have few options, such as an invasive surgery that removes or destroys the affected brain tissue.”

Robert Beach, M.D., Ph.D. professor of neurology at SUNY Upstate Medical University added: “The objective of NRTX-1001 is to add cells that have the potential to repair the circuits that are damaged in epilepsy and thus reduce seizure activity.”

There is a huge unmet medical need for an effective, long-term therapy. Right now, it’s estimated that three million Americans have epilepsy, and 25 to 35 percent live with ongoing seizures despite dozens of approved drugs on the market.

If this therapy works it might mean that 4,000 year old tablet will become a medical footnote, rather than a reminder that we still have work to do.

Stem Cell Agency Board Invests in 19 Discovery Research Programs Targeting Cancers, Heart Disease and Other Disorders

Dr. Judy Shizuru, Stanford University

While stem cell and gene therapy research has advanced dramatically in recent years, there are still many unknowns and many questions remaining about how best to use these approaches in developing therapies. That’s why the governing Board of the California Institute for Regenerative Medicine (CIRM) today approved investing almost $25 million in 19 projects in early stage or Discovery research.

The awards are from CIRM’s DISC2 Quest program, which supports  the discovery of promising new stem cell-based and gene therapy technologies that could be translated to enable broad use and ultimately, improve patient care.

“Every therapy that helps save lives or change lives begins with a researcher asking a simple question, “What if?”, says Dr. Maria T. Millan, the President and CEO of CIRM. “Our Quest awards reflect the need to keep supporting early stage research, to gain a deeper understanding of stem cells work and how we can best tap into that potential to advance the field.”

Dr. Judy Shizuru at Stanford University was awarded $1.34 million to develop a safer, less-toxic form of bone marrow or hematopoietic stem cell transplant (HCT). HCT is the only proven cure for many forms of blood disorders that affect people of all ages, sexes, and races worldwide. However, current methods involve the use of chemotherapy or radiation to destroy the patient’s own unhealthy blood stem cells and make room for the new, healthy ones. This approach is toxic and complex and can only be performed by specialized teams in major medical centers, making access particularly difficult for poor and underserved communities.

Dr. Shizuru proposes developing an antibody that can direct the patient’s own immune cells to kill diseased blood stem cells. This would make stem cell transplant safer and more effective for the treatment of many life-threatening blood disorders, and more accessible for people in rural or remote parts of the country.

Dr. Lili Yang at UCLA was awarded $1.4 million to develop an off-the-shelf cell therapy for ovarian cancer, which causes more deaths than any other cancer of the female reproductive system.

Dr. Yang is using immune system cells, called invariant natural killer T cells (iNKT) to attack cancer cells. However, these iNKT cells are only found in small numbers in the blood so current approaches involve taking those cells from the patient and, in the lab, modifying them to increase their numbers and strength before transplanting them back into the patient. This is both time consuming and expensive, and the patient’s own iNKT cells may have been damaged by the cancer, reducing the likelihood of success.

In this new study Dr. Yang will use healthy donor cord blood cells and, through genetic engineering, turn them into the specific form of iNKT cell therapy targeting ovarian cancer. This DISC2 award will support the development of these cells and do the necessary testing and studies to advance it to the translational stage.

Timothy Hoey and Tenaya Therapeutics Inc. have been awarded $1.2 million to test a gene therapy approach to replace heart cells damaged by a heart attack.

Heart disease is the leading cause of death in the U.S. with the highest incidence among African Americans. It’s caused by damage or death of functional heart muscle cells, usually due to heart attack. Because these heart muscle cells are unable to regenerate the damage is permanent. Dr. Hoey’s team is developing a gene therapy that can be injected into patients and turn their cardiac fibroblasts, cells that can contribute to scar tissue, into functioning heart muscle cells, replacing those damaged by the heart attack.

Two reasons to remember June 19th

Today marks two significant events for the Black community. June 19th is celebrated as Juneteenth, the day when federal troops arrived in Galveston, Texas to ensure that the enslaved people there were free. That moment came two and a half years after President Abraham Lincoln signed the Emancipation Proclamation into law.

June 19th is also marked as World Sickle Cell Awareness Day. It’s an opportunity to raise awareness about a disease that affects around 100,000 Americans, most of them Black, and the impact it has on the whole family and entire communities.

Sickle cell disease (SCD) is an inherited blood disorder that is caused by a genetic mutation. Instead of red blood cells being smooth and round and flowing easily through arteries and veins, the cells are sickle shaped and brittle. They can clog up arteries and veins, cutting off blood to vital organs, causing intense pain, organ damage and leading to premature death.

SCD can be cured with a bone marrow transplant, but that’s a risky procedure and most people with SCD don’t have a good match. Medications can help keep it under control but cannot cure it. People with SCD live, on average, 30 years less than a healthy adult.

CIRM has invested almost $60 million in 13 different projects, including five clinical trials, to try and develop a cure for SCD. There are encouraging signs of progress. For example, in July of 2020, Evie Junior took part in a CIRM-funded clinical trial where his own blood stem cells were removed then, in the laboratory, were genetically modified to repair the genetic mutation that causes the disease. Those cells were returned to him, and the hope is they’ll create a sickle cell-free blood supply. Evie hasn’t had any crippling bouts of pain or had to go to the hospital since his treatment.

CIRM has also entered into a unique partnership with the National Heart, Lung and Blood Institute (NHLBI) to co-fund cell and gene therapy programs under the NIH “Cure Sickle Cell” initiative.  The goal is to markedly accelerate the development of cell and gene therapies for SCD.

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

We will all keep working together to advance this research and develop a cure. Until then Juneteenth will be a reminder of the work that still lies ahead.

Creating a ‘bespoke’ approach to rare diseases

THIS BLOG IS ALSO AVAILABLE AS AN AUDIO CAST

Up until recently the word “bespoke” meant just one thing to me, a hand-made suit, customized and fitted to you. There’s a street in London, Saville Row, that specializes in these suits. They’re gorgeous. They’re also very expensive and so I thought I’d never have a bespoke anything.

I was wrong. Because CIRM is now part of a bespoke arrangement. It has nothing to do with suits, it’s far more important than that. This bespoke group is aiming to create tailor-made gene therapies for rare diseases.

It’s called the Bespoke Gene Therapy Consortium (BGTC). Before we go any further I should warn you there’s a lot of acronyms heading your way. The BGTC is part of the Accelerating Medicines Partnership® (AMP®) program. This is a public-private partnership between the National Institutes of Health (NIH), the U.S. Food and Drug Administration (FDA), and multiple public and private organizations, such as CIRM.

The program is managed by the Foundation for the NIH (FNIH) and it aims to develop platforms and standards that will speed the development and delivery of customized or ‘bespoke’ gene therapies that could treat the millions of people affected by rare diseases.

Why is it necessary? Well, it’s estimated that there are around 7,000 rare diseases and these affect between 25-30 million Americans. Some of these diseases affect only a few hundred, or even a few dozen people. With so few people they almost always struggle to raise the funds needed to do research to find an effective therapy. However, many of these rare diseases are linked to a mutation or defect in a single gene, which means they could potentially be treated by highly customizable, “bespoke” gene therapy approaches.

Right now, individual disease programs tend to try individual approaches to developing a treatment. That’s time consuming and expensive. The newly formed BGTC believes that if we create a standardized approach, we could develop a template that can be widely used to develop bespoke gene therapies quickly, more efficiently and less expensively for a wide array of rare diseases.

“At CIRM we have funded several projects using gene therapy to help treat, and even cure, people with rare diseases such as severe combined immunodeficiency,” says Dr. Maria T. Millan, the President and CEO of CIRM. “But even an agency with our resources can only do so much. This agreement with the Bespoke Gene Therapy Consortium will enable us to be part of a bigger partnership, one that can advance the field, overcome obstacles and lead to breakthroughs for many rare diseases.”

With gene therapy the goal is to identify the genetic defect that is causing the disease and then deliver a normal copy of the gene to the right tissues and organs in the body, replacing or correcting the mutation that caused the problem. But what is the best way to deliver that gene? 

The BGTC’s is focusing on using an adeno-associated virus (AAV) as a delivery vehicle. This approach has already proven effective in Leber congenital amaurosis (LCA), retinitis pigmentosa (RP), and spinal muscular atrophy. The consortium will test several different approaches using AAV gene therapies starting with basic research and supporting those all the way to clinical trials. The knowledge gained from this collaborative approach, including developing ways to manufacture these AAVs and creating a standard regulatory approach, will help build a template that can then be used for other rare diseases to copy.

As part of the consortium CIRM will identify specific rare disease gene therapy research programs in California that are eligible to be part of the AMP BGTC. CIRM funding can then support the IND-enabling research, manufacturing and clinical trial activities of these programs.

“This knowledge network/consortium model fits in perfectly with our mission of accelerating transformative regenerative medicine treatments to a diverse California and world,” says Dr. Millan. “It is impossible for small, often isolated, groups of patients around the world to fund research that will help them. But pooling our resources, our skills and knowledge with the consortium means the work we support here may ultimately benefit people everywhere.”

Stem cells help researchers map out glaucoma in search for new treatments

Glaucoma is the world’s leading cause of irreversible blindness. There is no cure and current treatments are only able to slow down the progression of the disease. Now research using stem cells to create a genetic blueprint of glaucoma is giving scientist a powerful new tool to combat the disease.

Glaucoma occurs when healthy retinal ganglion cells, which relay information from the eyes to the brain, are damaged and die. However, researchers were unable to really understand what was happening because the only way to look at retinal ganglion cells was through very invasive procedures.

So, researchers in Australia took skin cells from people with glaucoma and people with healthy eyes and, using the iPSC method, turned them into retinal ganglion cells. They were then able to map the genetic expression of these cells and compare the healthy cells with the diseased ones.

In an interview with Science Daily, Professor Joseph Powell , who led the team, says they were able to identify more than 300 unique genetic features which could provide clues as to what is causing the vision loss.

“The sequencing identifies which genes are turned on in a cell, their level of activation and where they are turned on and off like a road network with traffic lights. This research gives us a genetic roadmap of glaucoma and identifies 312 sites in the genome where these lights are blinking. Understanding which of these traffic lights should be turned off or on will be the next step in developing new therapies to prevent glaucoma.”

Powell says by identifying underlying causes for glaucoma researchers may be able to develop new, more effective therapies.

The study is published in Cell Genomics.

Join us to hear how stem cell and gene therapy are taking on diseases of aging

It is estimated that as many as 90 percent of people in industrialized countries who die every day, die from diseases of aging such as heart disease, stroke, and cancer. Of those still alive the numbers aren’t much more reassuring. More than 80 percent of people over the age of 65 have a chronic medical condition, while 68 percent have two or more.

Current medications can help keep some of those conditions, such as high blood pressure, under control but regenerative medicine wants to do a lot more than that. We want to turn back the clock and restore function to damaged organs and tissues and limbs. That research is already underway and we are inviting you to a public event to hear all about that work and the promise it holds.

On June 16th from 3p – 4.30p PST we are holding a panel discussion exploring the impact of regenerative medicine on aging. We’ll hear from experts on heart disease and stroke; we will look at other ground breaking research into aging; and we’ll discuss the vital role patients and patient advocates play in helping advance this work.

The discussion is taking place in San Francisco at the annual conference of the International Society for Stem Cell Research. But you can watch it from the comfort of your own home. That’s because we are going to live stream the event.

Here’s where you can see the livestream: https://www.youtube.com/watch?v=CaUgsc5alDI

And if you have any questions you would like the panel to answer feel free to send them to us at info@cirm.ca.gov

The power of the patient advocate: how a quick visit led to an $11M grant to fund a clinical trial

THIS BLOG IS ALSO AVAILABLE AS AN AUDIO CAST

Members of NFOSD visiting UC Davis in 2013

At the California Institute for Regenerative Medicine (CIRM) we are fortunate in having enough money to fund the most promising research to be tested in a clinical trial. Those are expensive projects, often costing tens of millions of dollars. But sometimes the projects that come to our Board start out years before in much more humble circumstances, raising money through patient advocates, tapping into the commitment and ingenuity of those affected by a disease, to help advance the search for a treatment.

That was definitely the case with a program the CIRM Board voted to approve yesterday, investing more than $11 million dollars to fund a Phase 2 clinical trial testing a cell therapy for dysphagia. That’s a debilitating condition that affects many people treated for head and neck cancer.

Patients with head and neck cancer often undergo surgery and/or radiation to remove the tumors. As a result, they may develop problems swallowing and this can lead to serious complications such as malnutrition, dehydration, social isolation, or a dependence on using a feeding tube. Patients may also inhale food or liquids into their lungs causing infections, pneumonia and death. The only effective therapy is a total laryngectomy where the larynx or voice box is removed, leaving the person unable to speak.

Dr. Peter Belafsky and his team at the University of California at Davis are developing a therapeutic approach using Autologous Muscle Derived Progenitor Cells (AMDC), cells derived from a biopsy of the patient’s own muscle, elsewhere in the body. Those AMDCs are injected into the tongue of the patient, where they fuse with existing muscle fibers to increase tongue strength and ability to swallow.

The $11,015,936 that Dr. Belafsky is getting from CIRM will enable them to test this approach in patients. But without grass roots support the program might never have made it this far.

Ed Steger is a long-term survivor of head and neck cancer, he’s also the President of the National Foundation of Swallowing Disorders (NFOSD). In 2007, after being treated for his cancer, Ed developed a severe swallowing disorder. It helped motivate him to push for better treatment options.

In 2013, a dozen swallowing disorder patients visited UC Davis to learn how stem cells might help people with dysphagia. (You can read about that visit here). Ed says: “We were beyond thrilled with the possibilities and drawing on patients and other UCD contacts our foundation raised enough funds to support a small UCD clinical trial under the guidance of Dr. Belafsky in mouse models that demonstrated these possibilities.”

A few years later that small funding by patients and their family members grew into a well-funded Phase I/II human clinical trial. Ed says the data that trial produced is helping advance the search for treatments.

“Skipping forward to the present, this has now blossomed into an additional $11 million grant, from CIRM, to continue the work that could be a game changer for millions of Americans who suffer annually from oral phase dysphagia. My hat is off to all those that have made this possible… the donors, patient advocates, and the dedicated committed researchers and physicians who are performing this promising and innovative research.”

Our hats are off to them too. Their efforts are making what once might have seemed impossible, a real possibility.

Replacement brain cells offer hope for Parkinson’s treatment

A new study that used adult blood stem cells to create replacement brain nerve cells appears to help rats with Parkinson’s.

In Parkinson’s, the disease attacks brain nerve cells that produce a chemical called dopamine. The lack of dopamine produces a variety of symptoms including physical tremors, depression, anxiety, insomnia and memory problems. There is no cure and while there are some effective treatments they tend to wear off over time.

In this study, researchers at Arizona State University took blood cells from humans and, using the iPSC method, changed those into dopamine-producing neurons. They then cultured those cells in the lab before implanting them in the brains of rats which had Parkinson’s-like symptoms.

They found that rats given cells that had been cultured in the lab for 17 days survived in greater numbers and seemed to be better at growing new connections in their brains, compared to rats given cells that had been cultured for 24 or 37 days.

In addition, those rats given larger doses of the cells experienced a complete reversal of their symptoms, compared to rats given smaller doses.

In a news release, study co-author Dr. Jeffrey Kordower, said: “We cannot be more excited by the opportunity to help individuals who suffer from [a] genetic form of Parkinson’s disease, but the lessons learned from this trial will also directly impact patients who suffer from sporadic, or non-genetic forms of this disease.”

The study, published in the journal npj Regenerative Medicine, says this approach might also help people suffering from other neurological diseases like Alzheimer’s or Huntington’s disease.

Smoking marijuana could be bad for your heart, but there is an unusual remedy

Millions of Americans use marijuana for medical reasons, such as reducing anxiety or helping ease the side effects of cancer therapy. Millions more turn to it for recreational reasons, saying it helps them relax. Now a new study says those who smoke marijuana regularly might be putting themselves at increased risk of heart disease and heart attack.

There has long been debate about the benefits versus the risks for using cannabis, with evidence on both sides to support each position. For example some studies have shown taking oral cannabinoids can help people cope with the nausea brought on by chemotherapy. Other studies have shown that regular use of marijuana can cause problems such as marijuana use disorder, a condition where the user is showing physical or psychological problems but has difficulty controlling or reducing their use of cannabis.

Now this latest study, from researchers at Stanford Medicine,  shows that THC, the psychoactive part of the drug, can cause inflammation in endothelial cells. These are the cells that line the interior of blood vessels. When these cells become inflamed it can cause a constriction of the vessels and reduce blood flow. Over time this can create conditions that increase the risk of heart disease and heart attack.

The researchers, led by Dr. Joe Wu, began by analyzing data from the UK Biobank. This included information about some 35,000 people who reported smoking marijuana. Of these around 11,000 smoked more than once a month. The researchers found that regular marijuana smokers:

  • Were significantly more likely than others to have a heart attack.
  • Were also more likely to have their first heart attack before the age of 50, increasing their risk of subsequent attacks.

The team then used the iPSC method to create human endothelial cells and, in the lab, found that THC appeared to promote inflammation in the cells. They also found signs it created early indications of atherosclerosis, where there is a buildup of fat and plaque in the arteries.

They then tested mice which had been bred to have high levels of cholesterol and who were given a high fat diet. Some of the mice were then injected with THC, at a level comparable to smoking one marijuana cigarette a day. Those mice had far larger amounts of atherosclerosis plaque in their arteries compared to the mice who didn’t get the THC.

In a news release, Dr.Wu, the lead author of the study, said: “There’s a growing public perception that marijuana is harmless or even beneficial. Marijuana clearly has important medicinal uses, but recreational users should think carefully about excessive use.”

On the bright side, the team also reported that the damage caused by THC can be stopped by genistein, a naturally occurring compound found in soy and fava beans. The study, in the journal Cell, also found that genistein blocked the bad impact of THC without impeding the good impacts.

“As more states legalize the recreational use of marijuana, users need to be aware that it could have cardiovascular side effects,” said Dr. Wu. “But genistein works quite well to mitigate marijuana-induced damage of the endothelial vessels without blocking the effects marijuana has on the central nervous system, and it could be a way for medical marijuana users to protect themselves from a cardiovascular standpoint.”

I have a confession. Deep down I’m shallow. So when something I am part of is acknowledged as one of the best, I delight in it (my fellow bloggers Katie and Esteban also delight in it, I am just more shameless about letting everyone know.)

And that is just what happened with this blog, The Stem Cellar. We have been named as one of the “22 best biology and stem cell blogs of 2022”. And not just by anyone. We were honored by Dr. Paul Knoepfler, a stem cell scientist, avid blogger and all-round renaissance man (full disclosure, Paul is a recipient of CIRM funding but that has nothing to do with this award. Obviously.)

We are particularly honored to be on the list because Paul includes some heavy hitters including The Signals Blog, a site that he describes this way:

“This one from our friends in Canada is fantastic. They literally have dozens of authors, which is probably the most of any stem cell-related website, and their articles include many interesting angles. They post really often too. I might rank Signal and The Stem Cellar as tied for best stem cell blog in 2021.”

Now I’m really blushing.

Other highly regarded blogs are EuroStemCell, the Mayo Clinic Regenerative Medicine Blog and Stem Cell Battles (by Don Reed, a good friend of CIRM’s)

Another one of the 22 is David Jensen’s California Stem Cell report which is dedicated to covering the work of, you guessed it, CIRM. So, not only are we great bloggers, we are apparently great to blog about. 

As a further demonstration of my modesty I wanted to point out that Paul regularly produces ‘best of’ lists, including his recent “50 influencers on stem cells on Twitter to follow” which we were also on.
