What makes an expert an expert?

When we launched our Facebook Live “Ask the Expert” series earlier this year we wanted to create an opportunity for people to hear from and question experts about specific diseases or disorders. The experts we turned to were medical ones, neurologists and neuroscientists in the case of the first two Facebook Live events, stroke and ALS.

Then we learned about a blog post on the ALS Advocacy website questioning our use of the word “expert”. The author, Cathy Collet, points out that doctors or scientists are far from the only experts about these conditions, that there are many people who, by necessity, have become experts on a lot of issues relating to ALS and any other disease.

Here’s Cathy’s blog. After you read it please let us know what you think: should we come up with a different title for the series, if so what would you suggest?

 

 

 

“Over the years I’ve experienced many “Ask the Experts” sessions related to ALS.  It’s always a panel of neuroscientists who talk a lot about ALS research and then take a few questions.

The “Expert” crown defaults to them.  They speak from the dais.  We get to listen a lot and ask.  They are by default “The Experts” in the fight against ALS.

But wait, there are all kinds of people with superb and valuable knowledge related to ALS –

  • There are people who know a lot about insurance.
  • There are people who know a lot about communication technology.
  • There are people who know a lot about low-tech hacks.
  • There are people who know a lot about suction machines.
  • There are people who know a lot about breathing.
  • There are people who know a lot about the FDA.
  • There are people who know a lot about moving a person on and off a commode.
  • There are people who know a lot about taxes.
  • There are people who know a lot about drugs.
  • There are people who know a lot about data.
  • There are people who know a lot about choking.
  • There are people who know a lot about financing research.
  • There are people who know a lot about stem cells.
  • There are people who know a lot about feeding tubes and nutrition.
  • There are people who know a lot about what’s important in living with the beast ALS.
  • There are people who know a lot about primary care in ALS.
  • There are people who know a lot about constipation.

Our default implication for the word experts being neuroscientists is revealing. There are many people in the fight against ALS, including those living with it, who know a lot.  We still live in a hierarchy where people with ALS and caregivers are at the bottom.

Words matter.  “Expert” is not a royal title to be owned by anyone by default.

It’s time for simple changes to some traditions.  “Ask the Neuroscientists,” anyone?

 

By the way, our next Facebook Live “Ask the ?” feature is targeting Sickle Cell Disease. It will be from noon till 1pm on Tuesday August 28th. More details, and maybe even a new name, to follow.

 

CIRM-supported study shows promise in fighting acute myeloid leukemia

Chemotherapy

Chemotherapy

For years chemotherapy has been a mainstay in the war against cancer. While it can be very effective it can also come with some nasty side effects. Since chemo works by killing rapidly growing cells, it not only hits the cancer cells, but can also hit other rapidly growing cells too, including those in our hair roots, which is why many people undergoing chemo lose their hair.

So, the key to a truly effective anti-cancer therapy is one that does as much damage as possible to the cancer cells, and as little as possible to all the healthy cells in the body. A therapy being developed by Cellerant Therapeutics seems to have found that sweet spot in a new therapy targeting acute myeloid leukemia (AML).

AML starts in the bone marrow and quickly moves into the blood, where it can spread to other parts of the body. It is the second most common form of leukemia and claims around 10,000 lives in the US every year. Chemotherapy is the main weapon used against AML but it can also cause nausea, hair loss and other complications and in most cases has limited effectiveness because, over time, the leukemia cells get used to it.

Cellerant 2013In a study published in the journal Blood Advances, Cellerant researchers explain the limitations of existing treatments.

“The current standard of care for acute myeloid leukemia (AML) is largely ineffective with very high relapse rates and low survival rates, mostly due to the inability to eliminate a rare population of leukemic stem cells (LSCs) that initiate tumor growth and are resistant to standard chemotherapy.”

Cellerant has developed a therapy called CLT030 which targets CLL1, a marker found on the surface of leukemia cells but not on normal blood stem cells. Preclinical studies in mice show CLT030 is able to zero in on this surface marker and attack the leukemia but do little damage to blood or other surrounding cells.

In a news release, Ram Mandalam, President and CEO of Cellerant, said this is encouraging news:

“AML remains a significant unmet medical need, and our therapy, CLT030, that can target leukemic stem cells precisely while minimally affecting normal hematopoietic stem cells could improve outcomes while avoiding much of the toxicities associated with conventional chemotherapy and other targeted therapeutics.”

Mandalam says they are now doing the late-stage preclinical testing to be able to apply to the Food and Drug Administration for permission to start a clinical trial. CIRM is funding this stage of the research.

 

ALS is in the spotlight in CIRM’s “Ask the Expert About ALS & Stem Cells” Facebook Live event

The Catch

San Francisco 49ers Dwight Clark makes his iconic “Catch” against the Dallas Cowboys

American Football great Dwight Clark was renowned for having the safest hands in the game when he played for the San Francisco 49ers. But in September 2015 he was diagnosed with ALS (also known as Lou Gehrig’s disease) after not being able to use those hands to open a package of sugar. Less than three years later he was dead.

Amyotrophic lateral sclerosis – ALS’ formal title – is a nasty disease that relentlessly destroys the nerve cells in the brain and spinal cord that control movement and breathing. It is always fatal. There are only two drugs approved for ALS and they don’t work for most people. There is no cure.

AskExpertsALSJUL2018

That’s why CIRM chose ALS to be the subject of its latest Facebook Live Ask the Expert event (click here for the event’s FaceBook Live page). There’s a real need for new approaches to help people battling this deadly condition. And CIRM is funding two clinical trials that hope to do just that.

This Ask the Expert event will feature Clive Svendsen, PhD, Director of Cedars-Sinai’s Board of Governors Regenerative Medicine Institute, and Robert Baloh, MD, PhD, Director of Neuromuscular Medicine at Cedars-Sinai. They’ll be joined by Ralph Kern, MD, Chief Operating Officer and Chief Medical Officer at  BrainStorm Cell Therapeutics. The panel will be completed by CIRM Senior Science Officer Lila Collins.

The four will discuss the clinical trials that CIRM is funding with Cedars-Sinai and BrainStorm, and look at other promising research taking place.

Ask the Experts About ALS and Stem Cells is an opportunity for everyone in the ALS community to hear about the very latest in stem cell research targeting this devastating disease,” Svendsen said. “There has recently been some progress in the search for new treatments, which has energized all of us looking for effective therapies—and one day, a cure.”

Because Facebook Live is an interactive event people will be able to post comments and ask questions of the experts.

Dr. Baloh says we are now at a crucial time in the search for new approaches to help people with ALS.

“Many researchers believe that stem cells and gene therapies hold great promise for finding effective treatments, and more trials are needed to explore that potential.”

Our Facebook Live event, “Ask the Experts About ALS and Stem Cells” is tomorrow – Tuesday, July 31st – from noon till 1pm PST. You can join us by logging on to Facebook and going to the FaceBook Live broadcast link at: https://bit.ly/2uYQ8wM

Also, make sure to “like” our FaceBook page before the event to receive a notification when we’ve gone live for this and future events.

We want to hear from you, so you will be able to post questions in real-time for the experts to answer or, you can email them directly to us beforehand at info@cirm.ca.gov

If you miss the event, not to worry. A recording of the session will be available in our FaceBook videos page shortly after the broadcast ends.

We look forward to seeing you there.

 

Stem Cell Roundup: Artificial Embryos to Study Miscarriage and ALS Insight – Muscle Repair Cells Go Rogue

Stem Cell Image of the Week: Artificial embryos for studying miscarriage (Adonica Shaw)

This week’s stem cell image of the week comes from a team of researchers from The University of Cambridge who published research in Nature Cell Biology earlier this week indicating they’d achieved a breakthrough in stem cell research that resulted in the generation of a key developmental step that’d never before been achieved when trying to generate an artificial embryo.

To create the artificial embryo, the scientists combined mouse embryonic stem cells with two other types of stem cells that are present in the very earliest stages of embryo development. The reseachers grew the three stem cell types into a dish and coaxed them into simulating a process called gastrulation – one of the very first events that happens during a creature’s development in which the early embryo begins reorganizing into more and more complex multilayer organ structures.

In an interview with The Next Web (TNW), Professor Magdalena Zernicka-Goetz, who led the research team, says:

”Our artificial embryos underwent the most important event in life in the culture dish. They are now extremely close to real embryos. To develop further, they would have to implant into the body of the mother or an artificial placenta.”

The goal of this research isn’t to create mice on demand. Its purpose is to gain insights into early life development. And that could lead to a giant leap in our understanding of what happens during the period in a woman’s pregnancy where the risk of miscarriage is highest.

According to professor Zernicka-Goetz,

“We can also now try to apply this to the equivalent human stem cell types and so study the very earliest events in human embryo development without actually having to use natural human embryos.The early stages of embryo development are when a large proportion of pregnancies are lost and yet it is a stage that we know very little about. Now we have a way of simulating embryonic development in the culture dish, so it should be possible to understand exactly what is going on during this remarkable period in an embryo’s life, and why sometimes this process fails.”

Muscle repair cells go rogue – a possible drug target for ALS?
Call it a case of a good cell gone bad. This week researchers at Sanford Burnham Prebys Medical Discovery Institute, report in Nature Cell Biology that fibro-adipogenic progenitors (FAPs) – cells that are critical in coordinating the repair of torn muscles – can turn rogue, causing muscles to wither and scar. This “Dr. Jekyl and Mr. Hype” discovery may lead to novel treatments for a number of incurable disorders like amyotrophic lateral sclerosis (ALS), spinal muscular atrophy (SMA) and spinal cord injury.

When muscle is strained, whether due to an acute injury or even weight-lighting, a consistent order of events occurs within the muscle. FAB cells enter the muscle tissue after immune cells called macrophages come in and gobble up dead tissue but before muscle stem cells are stimulated to regenerate the lost muscle. However, to the researchers’ surprise, something entirely different happens in the case of neuromuscular disorders like ALS where nerve signal connections to the muscles degenerate.

Once nerves are no longer attached to muscle and stop sending movement signals from the brain, the macrophages don’t infiltrate the muscle and instead the FAPs pile up in the muscle and never leave. And as a result, muscle stem cells are never activated. In ALS patients, this cellular train crash leads to progressive loss of muscle control to move the limbs and ultimately even to breathe.

The promising news from these findings, which were funded in part by CIRM, is that the team identified of an out-of-whack cell signaling pathway that is responsible for the breakdown in the rogue function of the FAP cells. The researchers hope further studies of this pathway’s role in muscle degeneration may lead to novel therapies and disease-screening technologies for ALS and other motor neuron diseases.

Stem cell therapy offers a glimpse of hope for a student battling a deadly cancer

“About a week later they gave me a call and mentioned the word ‘cancer’ to me. For a long time, I was depressed and then, I guess you accept it and try to make the most out of the time you have now.’

That is not something you expect to hear from a 24 year old. But for Daniel Apodaca that became, very suddenly, his reality. He was diagnosed with a rare, soft tissue cancer called epithelioid sarcoma. Fortunately for Daniel help was at hand, and a lot closer than he could ever have possibly anticipated.

Daniel is a student at UCLA. CIRM is funding a clinical trial run by UCLA’s Dr. Antoni Ribas that targets the same cancer Daniel is battling. The therapy re-programs a person’s own immune system to help fight the disease.

Daniel became patient #1 in that trial.

CNN reporter Rachel Crane profiled Dr. Ribas and the treatment he hopes will save Daniel’s life.

 

 

Research Targeting Prostate Cancer Gets Almost $4 Million Support from CIRM

Prostate cancer

A program hoping to supercharge a patient’s own immune system cells to attack and kill a treatment resistant form of prostate cancer was today awarded $3.99 million by the governing Board of the California Institute for Regenerative Medicine (CIRM)

In the U.S., prostate cancer is the second most common cause of cancer deaths in men.  An estimated 170,000 new cases are diagnosed each year and over 29,000 deaths are estimated in 2018.  Early stage prostate cancer is usually managed by surgery, radiation and/or hormone therapy. However, for men diagnosed with castrate-resistant metastatic prostate cancer (CRPC) these treatments often fail to work and the disease eventually proves fatal.

Poseida Therapeutics will be funded by CIRM to develop genetically engineered chimeric antigen receptor T cells (CAR-T) to treat metastatic CRPC. In cancer, there is a breakdown in the natural ability of immune T-cells to survey the body and recognize, bind to and kill cancerous cells. Poseida is engineering T cells and T memory stem cells to express a chimeric antigen receptor that arms these cells to more efficiently target, bind to and destroy the cancer cell. Millions of these cells are then grown in the laboratory and then re-infused into the patient. The CAR-T memory stem cells have the potential to persist long-term and kill residual cancer calls.

“This is a promising approach to an incurable disease where patients have few options,” says Maria T. Millan, M.D., President and CEO of CIRM. “The use of chimeric antigen receptor engineered T cells has led to impressive results in blood malignancies and a natural extension of this promising approach is to tackle currently untreatable solid malignancies, such as castrate resistant metastatic prostate cancer. CIRM is pleased to partner on this program and to add it to its portfolio that involves CAR T memory stem cells.”

Poseida Therapeutics plans to use the funding to complete the late-stage testing needed to apply to the Food and Drug Administration for the go-ahead to start a clinical trial in people.

Quest Awards

The CIRM Board also voted to approve investing $10 million for eight projects under its Discovery Quest Program. The Quest program promotes the discovery of promising new stem cell-based technologies that will be ready to move to the next level, the translational category, within two years, with an ultimate goal of improving patient care.

Among those approved for funding are:

  • Eric Adler at UC San Diego is using genetically modified blood stem cells to treat Danon Disease, a rare and fatal condition that affects the heart
  • Li Gan at the Gladstone Institutes will use induced pluripotent stem cells to develop a therapy for a familial form of dementia
  • Saul Priceman at City of Hope will use CAR-T therapy to develop a treatment for recurrent ovarian cancer

Because the amount of funding for the recommended applications exceeded the money set aside, the Application Subcommittee voted to approve partial funding for two projects, DISC2-11192 and DISC2-11109 and to recommend, at the next full Board meeting in October, that the projects get the remainder of the funds needed to complete their research.

The successful applications are:

Stem cell treatment for spinal cord injury offers improved chance of independent life for patients

A spinal cord injury is devastating, changing a person’s life in a heartbeat. In the past there was little that doctors could do other than offer pain relief and physical therapy to try and regain as much muscle function as possible. That’s why the latest results from the CIRM-supported Asterias Biotherapeutics spinal cord injury trial are so encouraging.

Asterias is transplanting what they call AST-OPC1 cells into patients who have suffered injuries that left them paralyzed from the neck down.  AST-OPC1 are oligodendrocyte progenitor cells, which develop into cells that support and protect nerve cells in the central nervous system, the area damaged in spinal cord injury. It’s hoped the treatment will restore connections at the injury site, allowing patients to regain some movement and feeling.

The latest results seem to suggest they are doing just that.

In a news release, Asterias reports that of the 25 patients treated in this clinical trial none have experienced serious side effects. They also reported that magnetic resonance imaging (MRI) tests show that more than 95 percent of the patients have shown evidence of what’s called “tissue matrix” at the injury site. This is encouraging because it suggests the implanted cells are engrafting and helping prevent a cavitation, a serious process that often occurs in spinal cord injuries and can lead to permanent loss of muscle and sensory function plus chronic pain.

The study also shows that after six months:

  • 100 percent of the patients in Group 5 (who received 20 million cells) have recovered at least one motor level (for example increased ability to use their arms) on at least one side
  • Two patients in Group 5 recovered one motor level on both sides
  • Altogether four of the 25 patients have recovered two or more motor levels on at least one side.

Not surprisingly Ed Wirth, the Chief Medical Officer at Asterias, was pleased with the results:

“The results from the study remain encouraging as the six-month follow-up data continued to demonstrate a positive safety profile and show that the AST-OPC1 cells are successfully engrafting in patients.”

While none of the patients are able to walk, just regaining some use of their arms or hands can have a hugely important impact on their quality of life and their ability to lead an independent life. And, because lifetime costs of taking care of someone who is paralyzed from the neck or chest down can run as high as $5 million, anything that increases a patient’s independence can have a big impact on those costs.

The impact of this research is helping change the lives of the patients who received it. One of those patients is Jake Javier. We have blogged about Jake several times over the last two years and recently showed this video about his first year at Cal Poly and how Jake is turning what could have been a life-ending event into a life-affirming one.

 

CIRM Supported Scientist Makes Surprising Discovery with Parasitic Gut Worms

It’s no secret that researchers have long believed adult stem cells could contribute to wound healing in the gut and skin, but in a new paper in Nature — a group of scientists at UC San Francisco made a surprising discovery.

Through several experiments using parasitic worms in the mouse gut, they found that as parasites dug into the intestinal walls of mice, the gut responded in an unexpected way – by reactivating a type of cell growth previously seen in fetal tissues.

So why is this important?

Simply put, it gives scientists new targets to go after. According to UCSF CIRM supported scientist Ophir Klein, MD, Ph.D., this discovery could be paradigm-shifting in terms of our understanding of how the mammalian body can repair damage and could help scientists develop more ways to enhance the body’s natural healing abilities.

Adult stem cells in the intestines are vital for maintaining the digestive status quo. The gut lining is made up of epithelial cells which absorb nutrients and produce protective mucus. These cells are replaced every few days by the stem cells at the base of crypts — indentations in the gut lining. Researchers expected that the same stem cells could also help repair tears in the gut.

How did they do it?

Larvae from parasites like H. polygyrus invade the gut lining in a mouse’s intestine, burying themselves to develop in the tissue. Based on prevailing ideas in the field, the scientists predicted that, in response, nearby stem cells would increase their productivity and patch up the worm-created wounds, but that is not what happened.

Instead, signs of the stem cells in worm-infected areas disappeared entirely; fluorescent markers that should have been expressed by one of the genes in the regular stem cell program completely vanished. And yet, even with no identifiable stem cells in the area, the wounded tissue regenerated more quickly than ever.

Researchers spent years trying to resolve this mystery and after a number of false starts and dead ends, the team eventually noticed the recurrence of a different gene, known as Sca-1.

Using antibody staining for the Sca-1 protein, the researchers realized that where the stem cell genes had disappeared, a different gene program was expressed instead: one that resembled the way that mouse guts develop in utero.

Upon their discovery, the researchers wondered whether the reactivation of this fetal program was a specific response to parasite infections, or if it could be a general strategy for many kinds of gut injury. Additional experiments showed that shutting down gut stem cells with irradiation or genetically targeting them for destruction triggered aspects of the same response: despite an absence of detectable stem cell activity, undifferentiated tissue grew rapidly nonetheless.

Later, once the acute injury is repaired, the gut may return to the normal stem cell program of producing differentiated cells that perform specific functions.

Many other injured tissues could benefit from the ability to quickly and efficiently make generalized repairs before returning to specialized adult cell production, opening up therapeutic opportunities. For example, developing treatments that bestow an ability to control the change between adult and fetal genetic programs might offer new strategies to manage conditions such as inflammatory bowel disease (IBD).

Early CIRM support helps stem cell pioneer develop promising new therapy for cancer

Irv Weissman

When you get praise from someone who has been elected to the National Academy of Sciences and has been named California Scientist of the Year you know you must be doing something right.

That’s how we felt the other day when Irv Weissman, Director of the Stanford Institute of Stem Cell Biology and Regenerative Medicine, issued a statement about how important the support of CIRM was in advancing his research.

The context was the recent initial public offering (IPO) of Forty Seven Inc.. a company co-founded by Dr. Weissman. That IPO followed news that two Phase 2 clinical trials being run by Forty Seven Inc. were demonstrating promising results against hard-to-treat cancers.

Dr. Weissman says the therapies used a combination of two monoclonal antibodies, 5F9 from Forty Seven Inc. and Rituximab (an already FDA-approved treatment for cancer and rheumatoid arthritis) which:

“Led to about a 50% overall remission rate when used on patients who had relapsed, multi-site disease refractory to rituximab-plus-chemotherapy. Most of those patients have shown a complete remission, although it’s too early to tell if this is complete for life.”

5F9 attacks a molecule called CD47 that appears on the surface of cancer cells. Dr. Weissman calls CD47 a “don’t eat me signal” that protects the cancer against the body’s own immune system. By blocking the action of CD47, 5F9 strips away that “don’t eat me signal” leaving the cancer vulnerable to the patient’s immune system. We have blogged about this work here and here.

The news from these trials is encouraging. But what was gratifying about Dr. Weissman’s statement is his generosity in sharing credit for the work with CIRM.

Here is what he wrote:

“What is unusual about Forty Seven is that not only the discovery, but its entire preclinical development and testing of toxicity, etc. as well as filing two Investigational New Drug [IND] applications to the Food and Drug Administration (FDA) in the US and to the MHRA in the UK, as well as much of the Phase 1 trials were carried out by a Stanford team led by two of the discoverers, Ravi Majeti and Irving Weissman at Stanford, and not at a company.

The major support came from the California Institute of Regenerative Medicine [CIRM], funded by Proposition 71, as well as the Ludwig Cancer Research Foundation at the Ludwig Center for Cancer Stem Cell Research at Stanford. CIRM will share in downstream royalties coming to Stanford as part of the agreement for funding this development.

This part of the state initiative, Proposition 71, is highly innovative and allows the discoverers of a field to guide its early phases rather than licensing it to a biotech or a pharmaceutical company before the value and safety of the discovery are sufficiently mature to be known. Most therapies at early-stage biotechs are lost in what is called the ‘valley of death’, wherein funding is very difficult to raise; many times the failure can be attributed to losing the expertise of the discoverers of the field.”

Dr. Weissman also had praise for CIRM’s funding model which requires companies that produce successful, profitable therapies – thanks to CIRM support – to return a portion of those profits to California. Most other funding agencies don’t have those requirements.

“US federal funds, from agencies such as the National Institutes of Health (NIH) similarly support discovery but cannot fund more than a few projects to, and through, early phase clinical trials. And, under the Bayh-Dole Act, the universities keep all of the equity and royalties derived from licensing discoveries. In that model no money flows back to the agency (or the public), and nearly a decade of level or less than level funding (at the national level) has severely reduced academic research. So this experiment of funding (the NIH or the CIRM model) is now entering into the phase that the public will find out which model is best for bringing new discoveries and new companies to the US and its research and clinical trials community.”

We have been funding Dr. Weissman’s work since 2006. In fact, he was one of the first recipients of CIRM funding.  It’s starting to look like a very good investment indeed.

 

Video: Behind the scenes of a life-saving gene therapy stem cell treatment

“We were so desperate. When we heard about this treatment were willing to do anything to come here.”

In the above quote from Zahraa El Kerdi, “here” refers to UCLA, a world away from her hometown in Lebanon. In September 2015, Zahree gave birth to a son, Hussein, who appeared perfectly healthy. But by six months, he was barely clinging to life due to an inherited blood disorder, ADA-SCID, also called Bubble Baby disease. The disorder left Hussein without a functioning immune system so even a common cold could prove deadly. In fact, SCID babies rarely survive past one year of age. Up until now, no treatment options existed for the disease.

But Zahraa and her husband Ali heard about a CIRM-funded clinical trial, led by Donald Kohn, M.D. at UCLA, that could modify Hussein’s blood stem cells to fix the gene problem that’s causing his disease. The El Kerdi’s 7500-mile journey to save Hussein’s life is captured in a wonderful, five-minute video produced by UCLA’s Broad Stem Cell Research Center.

With before and after scenes of Hussein’s treatment as well as animation describing how the therapy works, the short documentary is equal parts heart wrenching, uplifting and educational. Basically, what I’m trying to say is, it’s a must-see and available to view above.
