Searching for a Cure for HIV/AIDS: Stem Cells and World AIDS Day

World-AIDS-Day

It’s been 26 years since the first World AIDS Day was held in 1988—and the progress that the international scientific community has made towards eradicating the disease has been unparalleled. But there is much more work to be done.

One of the most promising areas of HIV/AIDS research has been in the field of regenerative medicine. As you observe World AIDS Day today, we invite you to take a look at some recent advances from CIRM-funded scientists and programs that are well on their way to finding ways to slow, halt and prevent the spread of HIV/AIDS:

10 Years/10 Therapies: 10 Years after its Founding CIRM will have 10 Therapies Approved for Clinical Trials

In 2004, when 59 percent of California voters approved the creation of CIRM, our state embarked on an unprecedented experiment: providing concentrated funding to a new, promising area of research. The goal: accelerate the process of getting therapies to patients, especially those with unmet medical needs.

Having 10 potential treatments expected to be approved for clinical trials by the end of this year is no small feat. Indeed, it is viewed by many in the industry as a clear acceleration of the normal pace of discovery. Here are our first 10 treatments to be approved for testing in patients.

HIV/AIDS. The company Calimmune is genetically modifying patients’ own blood-forming stem cells so that they can produce immune cells—the ones normally destroyed by the virus—that cannot be infected by the virus. It is hoped this will allow the patients to clear their systems of the virus, effectively curing the disease.

Spinal Cord Injury. The company Asterias Biotherapeutics uses cells derived from embryonic stem cells to heal the spinal cord at the site of injury. They mature the stem cells into cells called oligodendrocyte precursor cells that are injected at the site of injury where it is hoped they can repair the insulating layer, called myelin, that normally protects the nerves in the spinal cord.

Heart Disease. The company Capricor is using donor cells derived from heart stem cells to treat patients developing heart failure after a heart attack. In early studies the cells appear to reduce scar tissue, promote blood vessel growth and improve heart function.

Solid Tumors. A team at the University of California, Los Angeles, has developed a drug that seeks out and destroys cancer stem cells, which are considered by many to be the reason cancers resist treatment and recur. It is believed that eliminating the cancer stem cells may lead to long-term cures.

Leukemia. A team at the University of California, San Diego, is using a protein called an antibody to target cancer stem cells. The antibody senses and attaches to a protein on the surface of cancer stem cells. That disables the protein, which slows the growth of the leukemia and makes it more vulnerable to other anti-cancer drugs.

Sickle Cell Anemia. A team at the University of California, Los Angeles, is genetically modifying a patient’s own blood stem cells so they will produce a correct version of hemoglobin, the oxygen carrying protein that is mutated in these patients, which causes an abnormal sickle-like shape to the red blood cells. These misshapen cells lead to dangerous blood clots and debilitating pain The genetically modified stem cells will be given back to the patient to create a new sickle cell-free blood supply.

Solid Tumors. A team at Stanford University is using a molecule known as an antibody to target cancer stem cells. This antibody can recognize a protein the cancer stem cells carry on their cell surface. The cancer cells use that protein to evade the component of our immune system that routinely destroys tumors. By disabling this protein the team hopes to empower the body’s own immune system to attack and destroy the cancer stem cells.

Diabetes. The company Viacyte is growing cells in a permeable pouch that when implanted under the skin can sense blood sugar and produce the levels of insulin needed to eliminate the symptoms of diabetes. They start with embryonic stem cells, mature them part way to becoming pancreas tissues and insert them into the permeable pouch. When transplanted in the patient, the cells fully develop into the cells needed for proper metabolism of sugar and restore it to a healthy level.

HIV/AIDS. A team at The City of Hope is genetically modifying patients’ own blood-forming stem cells so that they can produce immune cells—the ones normally destroyed by the virus—that cannot be infected by the virus. It is hoped this will allow the patients to clear their systems of the virus, effectively curing the disease

Blindness. A team at the University of Southern California is using cells derived from embryonic stem cell and a scaffold to replace cells damaged in Age-related Macular Degeneration (AMD), the leading cause of blindness in the elderly. The therapy starts with embryonic stem cells that have been matured into a type of cell lost in AMD and places them on a single layer synthetic scaffold. This sheet of cells is inserted surgically into the back of the eye to replace the damaged cells that are needed to maintain healthy photoreceptors in the retina.

UCLA team cures infants of often-fatal “bubble baby” disease by inserting gene in their stem cells; sickle cell disease is next target

Poopy diapers, ear-splitting cries, and sleepless nights: sure, the first few weeks of parenthood are grueling but those other moments of cuddling and kissing your little baby are pure bliss.

That wasn’t the case for Alysia and Christian Padilla-Vacarro of Corona, California. Close contact with their infant daughter Evangelina, born in 2012, was off limits. She was diagnosed with a genetic disease that left her with no immune system and no ability to fight off infections so even a minor cold could kill her.

Evangelina was born with Severe Combined Immunodeficiency (SCID) also called “bubble baby” disease, a term coined in the 1970s when the only way to manage the disease was isolating the child in a super clean environment to avoid exposure to germs. Bone marrow transplants from a matched sibling offer a cure but many kids don’t have a match, which makes a transplant very risky. Sadly, many SCID infants die within the first year of life.

Until now, that is.

Today, a UCLA research team led by Donald Kohn, M.D., announced a stunning breakthrough cure that saved Evangelina’s life and all 18 children who have so far participated in the clinical trial. Kohn—the director of UCLA’s Human Gene Medicine Program—described the treatment strategy in a video interview with CIRM (watch the video below):

“We collect some of the baby’s own bone marrow, isolate the [blood] stem cells, add the gene that they’re missing that their immune system needs and then transplant the cells back to them. “

Inserting the missing gene, called ADA, into the blood stem cells restores the cells’ ability to produce a healthy immune system. And since the cells originally came from the infant, there’s no worry about the possible life-threatening complications from receiving non-matched donor cells.

This breakthrough didn’t occur overnight. Kohn and colleagues have been plugging away for over twenty years carrying out trials, observing their limitations and going back to lab to improve the technology. Their dedication has paid off. As Kohn states in a press release:

“All of the children with SCID that I have treated in these stem cell clinical trials would have died in a year or less without this gene therapy, instead they are all thriving with fully functioning immune systems.”

For the Padilla-Vacarro family, the dark days after Evangelina’s grave diagnosis have given way to a bright future. Alysia, Evangelina’s mom, poignantly recalled her daughter’s initial recovery:

”It was only around six weeks after the procedure when Dr. Kohn told us Evangelina can finally be taken outside. To finally kiss your child on the lips, to hold her, it’s impossible to describe what a gift that is. I gave birth to my daughter, but Dr. Kohn gave my baby life.”

The team’s next step is to get approval by the Food and Drug Administration (FDA) to provide this treatment to all SCID infants missing the ADA gene.

At the same time, Kohn and colleagues are adapting this treatment approach to cure sickle cell disease, a genetic disease that leads to sickle shaped red blood cells. These misshapen cells are prone to clumping causing debilitating pain, risk of stroke, organ damage and a shortened life span. CIRM is providing over $13 million in funding to support the UCLA team’s clinical trial set to start early next year.

What everybody needs to know about CIRM: where has the money gone

It’s been almost ten years since the voters of California created the Stem Cell Agency when they overwhelmingly approved Proposition 71, providing us $3 billion to help fund stem cell research.

In the last ten years we have made great progress – we will have ten projects that we are funding in or approved to begin clinical trials by the end of this year, a really quite remarkable achievement – but clearly we still have a long way to go. However, it’s appropriate as we approach our tenth anniversary to take a look at how we have spent the money, and how much we have left.

Of the $3 billion Prop 71 generates around $2.75 billion was set aside to be awarded to research, build laboratories etc. The rest was earmarked for things such as staff and administration to help oversee the funding and awards.

Of the research pool here’s how the numbers break down so far:

  • $1.9B awarded
  • $1.4B spent
  • $873M not awarded

So what’s the difference between awarded and spent? Well, unlike some funding agencies when we make an award we don’t hand the researcher all the cash at once and say “let us know what you find.” Instead we set a series of targets or milestones that they have to reach and they only get the next installment of the award as they meet each milestone. The idea is to fund research that is on track to meet its goals. If it stops meetings its goals, we stop funding it.

Right now our Board has awarded $1.9B to different institutions, companies and researchers but only $1.4B of that has gone out. And of the remainder we estimate that we will get around $100M back either from cost savings as the projects progress or from programs that are cancelled because they failed to meet their goals.

So we have approximately $1B for our Board to award to new research, which means at our current rate of spending we’ll have enough money to be able to continue funding new projects until around 2020. Because these are multi-year projects we will continue funding them till around 2023 when those projects end and, theoretically at least, we run out of money.

But we are already working hard to try and ensure that the well doesn’t run dry, and that we are able to develop other sources of funding so we can continue to support this work. Without us many of these projects are at risk of dying. Having worked so hard to get these projects to the point where they are ready to move out of the laboratory and into clinical trials in people we don’t want to see them fall by the wayside for lack of support.

Of the $1.9B we have awarded, that has gone to 668 awards spread out over five different categories:

CIRM spending Oct 2014

Increasingly our focus is on moving projects out of the lab and into people, and in those categories – called ‘translational’ and ‘clinical’ – we have awarded almost $630M in funding for more than 80 active programs.

Under our new CIRM 2.0 plan we hope to speed up the number of projects moving into clinical trials. You can read more about how we plan on doing there in this blog.

It took Jonas Salk almost 15 years to develop a vaccine for polio but those years of hard work ended up saving millions of lives. We are working hard to try and achieve similar results on dozens of different fronts, with dozens of different diseases. That’s why, in the words of our President & CEO Randy Mills, we come to work every day as if lives depend on us, because lives depend on us.

Stem Cell Stories that Caught our Eye: Skin Cells to Brain Cells in One Fell Swoop, #WeAreResearch Goes Viral, and Genes Helps Stem Cells Fight Disease

Here are some stem cell stories that caught our eye this past week. Some are groundbreaking science, others are of personal interest to us, and still others are just fun.

Building a Better Brain Cell. Thanks to advances in stem cell biology, scientists have found ways to turn adult cells, such as skin cells, back into cells that closely resemble embryonic stem cells. They can then coax them into becoming virtually any cell in the body.

But scientists have more recently begun to devise ways to change cells from one type into another without first having to go back to a stem cell-like state. And now, a team from Washington University in St. Louis has done exactly that.

As reported this week in New Scientist, researcher Andrew Yoo and his team used microRNAs—a type of ‘signaling molecule’—to reprogram adult human skin cells into medium spiny neurons(MSNs), the type of brain cell involved in the deadly neurodegenerative condition, Huntington’s disease.

“Within four weeks the skin cells had changed into MSNs. When put into the brains of mice, the cells survived for at least six months and made connections with the native tissue,” explained New Scientist’s Clare Wilson.

This process, called ‘transdifferentiation,’ has the potential to serve as a faster, potentially safer alternative to creating stem cells.

#WeAreResearch Puts a Face on Science. The latest research breakthroughs often focus on the science itself, and deservedly so. But exactly who performed that research, the close-knit team who spent many hours at the lab bench and together worked to solve a key scientific problem, can sometimes get lost in the shuffle.

New Genes Help Stem Cells Fight Infection. Finally, UCLA scientists have discovered how stem cells ‘team up’ with a newly discovered set of genes in order to stave off infection.

Reporting in the latest issue of the journal Current Biology, and summarized in a UCLA news release, Julian Martinez-Agosto and his team describe how two genes—adorably named Yorkie and Scalloped—set in motion a series of events, a molecular Rube Goldberg device, that transforms stem cells into a type of immune system cell.

Importantly, the team found that without these genes, the wrong kind of cell gets made—meaning that these genes play a central role in the body’s healthy immune response.

Mapping out the complex signaling patterns that exist between genes and cells is crucial as researchers try and find ways to, in this case, improve the body’s immune response by manipulating them.

First of its kind stem cell production facility sets its sights on deadly childhood disease

We are used to hearing about immune suppression when transplanting organs or cells from one person to another. It’s a necessary step in preventing the body from attacking the transplanted material. Now Children’s Hospital of Orange County (CHOC) has just unveiled its newest tool to treat rare childhood diseases. Instead of focusing on immune suppression this focuses on immune-matching.

CHOC’s new stem cell production facility

CHOC has opened up a new stem cell production facility. It’s funded by CIRM and it’s a state-of-the-art mini clean room/manufacturing facility that will allow researchers to produce patient-specific cells for future immune-matching therapies.

“We are excited. We’ve been planning this for at least five years,” says Philip Schwartz, Ph.D., senior scientist at the CHOC Children’s Research Institute and managing director of the National Human Neural Stem Cell Resource.

“The major thing is that the footprint is much smaller than a traditional stem cell manufacturing facility, it’s all housed in one room so that keeps the cost down. The device we use to reproduce the cells is also much smaller so this set up doesn’t require multiple rooms and complex pass-throughs as you move from one room to another. All that meant the cost was only around $500,000 which is many times smaller than the more conventional facility.”

Dr. Schwartz is wasting little time putting the new facility to work. It’s already up and running and culturing cells for his work in developing a treatment for mucopolysaccharidosis (MPS-1), a rare neurodegenerative disease that usually kills children before the age of 10.

He is working on a kind of 1-2 punch approach to the disease. Using donated umbilical cord blood to help replace the child’s damaged immune system and then turning some of those blood stem cells into neural cells, the kind damaged by MPS-1, and transplanting those into the brain to repair and prevent further damage.

“This is a really interesting approach. Bone marrow transplants treat a neck down disease. Brain transplants treat a neck up disease. But conditions like MPS-1 are system wide and need both a neck down and neck up approach. Our approach could help combine those and because the cells are carefully matched also mean they won’t need to be on immune-suppressant therapy for life.”

Dr. Schwartz says animal studies using this two pronged approach have been very encouraging but he cautions there is still a lot of work to do before it would be ready for a clinical trial in people. However, if this approach is effective then it could be useful for more than just MPS-1:

“I have a high level of confidence that this will work and if it does work then we can use it in other conditions as well, such as Multiple Sclerosis. Some clinical studies show that MS patients with leukemia who got a bone marrow transplant also saw a decrease in their MS symptoms.”
