Stem Cell Agency Awards Almost $4 Million to Develop a Treatment for Spinal Degeneration

Today the governing Board of the California Institute for Regenerative Medicine (CIRM) awarded $3.9 million to Ankasa Regenerative Therapeutics for a promising approach to treat a degenerative condition that can cause chronic, progressive back pain.

As we get older, the bones, joints and ligaments in our back become weak and less able to hold the spinal column in alignment.  As a result, an individual vertebral bone in our spine may slip forward over the one below it, compressing the nerves in the spine, and causing lower back pain or radiating pain.  This condition, called degenerative spondylolisthesis, primarily affects individuals over the age of 50 and, if left untreated, can cause intense pain and further degeneration of adjacent regions of the spine.

Current treatment usually involves taking bone from one of the patient’s other bones, and moving it to the site of the injury.  The transplanted bone contains stem cells necessary to generate new bone.  However, there is a caveat to this approach— as we get older the grafts become less effective because the stem cells in our bones are less efficient at making new bone.  The end result is little or no bone healing. 

Ankasa has developed ART352-L, a protein-based drug product meant to enhance the bone healing properties of these bone grafts.  ART352-L works by stimulating bone stem cells to  increase the amount of bone produced by the graft.

The award is in the form of a CLIN1 grant, with the goal of completing the testing needed to apply to the Food and Drug Administration (FDA) for permission to start a clinical trial in people.

This is a project that CIRM has supported through earlier phases of research.

“We are excited to see the development that this approach has made since its early stages and reflects our commitment to supporting the most promising science and helping it advance to the clinic,” says Maria T. Millan, MD, President & CEO of CIRM. “There is an unmet medical need in older patients with bone disorders such as degenerative spondylolisthesis.  As our population ages, it is important for us to invest in potential treatments such as these that can help alleviate a debilitating condition that predisposes to additional and fatal medical complications.”

Newly developed biosensor can target leukemic stem cells

Every three minutes, one person in the United States is diagnosed with a blood cancer, which amounts to over 175,000 people every year. Every nine minutes, one person in the United States dies from a blood cancer, which is over 58,000 people every year. These eye opening statistics from the Leukemia & Lymphoma Society demonstrate why almost one in ten cancer deaths in 2018 were blood cancer related.

For those unfamiliar with the term, a blood cancer is any type of cancer that begins in blood forming tissue, such as those found in the bone marrow. One example of a blood cancer is leukemia, which results in the production of abnormal blood cells. Chemotherapy and radiation are used to wipe out these cells, but the blood cancer can sometimes return, something known as a relapse.

What enables the return of a blood cancer such as leukemia ? The answer lies in the properties of cancer stem cells, which have the ability to multiply and proliferate and can resist the effects of certain types of chemotherapy and radiation. Researchers at Tel Aviv University are looking to decrease the rate of relapse in blood cancer by targeting a specific type of cancer stem cell known as a leukemic stem cell, which are often found to be the most malignant.

Dr. Michael Milyavsky and his team at Tel Aviv University have developed a biosensor that is able to isolate, label, and target specific genes found in luekemic stem cells. Their findings were published on January 31, 2019 in Leukemia.

In a press release Dr. Milyavsky said:

“The major reason for the dismal survival rate in blood cancers is the inherent resistance of leukemic stem cells to therapy, but only a minor fraction of leukemic cells have high regenerative potential, and it is this regeneration that results in disease relapse. A lack of tools to specifically isolate leukemic stem cells has precluded the comprehensive study and specific targeting of these stem cells until now.”

In addition to isolating and labeling leukemic stem cells, Dr. Milyavsky and his team were able to demonstrate that the leukemic stem cells labeled by their biosensor were sensitive to an inexpensive cancer drug, highlighting the potential this technology has in creating more patient-specific treatment options.

In the article, Dr. Milyavsky said:

” Using this sensor, we can perform personalized medicine oriented to drug screens by barcoding a patient’s own leukemia cells to find the best combination of drugs that will be able to target both leukemia in bulk as well as leukemia stem cells inside it.”

The researchers are now investigating genes that are active in leukemic stem cells in the hope finding other druggable targets.

CIRM has funded two clinical trials that also use a more targeted approach for cancer treatment. One of these trials uses an antibody to treat chronic lymphocytic leukemia (CLL) and the other trial uses a different antibody to treat acute myeloid leukemia (AML).

Stem cell byproducts provide insight into cure for spina bifida

Some of you might remember a movie in the early 2000s by the name of “Miracle in Lane 2”. The film is based on an inspirational true story and revolves around a boy named Justin Yoder entering a soapbox derby competition. In the movie, Justin achieves success as a soapbox derby driver while adapting to the challenges of being in a wheelchair.

Scene from “Miracle in Lane 2”

The reason that Justin is unable to walk is due to a birth defect known as spina bifida, which causes an incomplete closing of the backbone portion of the spinal cord, exposing tissue and nerves. In addition to difficulties with walking, other problems associated with this condition are problems with bladder or bowel control and accumulation of fluid in the brain.

According to the Center for Disease Control (CDC) , each year about 1,645 babies in the US are born with spina bifida, with Hispanic women having the highest rate of children born with the condition. There is currently no cure for this condition, but researchers at UC Davis are one step closer to changing that.

Dr. Aijun Wang, Dr. Diana Farmer, and their research team have identified crucial byproducts produced by stem cells that play an important role in protecting neurons. These byproducts could assist with improving lower-limb motion in patients with spina bifida.

Prior to this discovery, Dr. Farmer and Dr. Wang demonstrated that prenatal surgery combined with connective tissue (e.g. stromal cells) derived from stem cells improved hind limb control in dogs with spina bifida. Below you can see a clip of two English bulldogs with spina bifida who are now able to walk.

Their findings were published in the Journal of the Federation of American Societies for Experimental Biology on February 12, 2019.

The team will use their findings to perfect the neuroprotective qualities of a stem cell treatment developed to improve locomotive problems associated with spina bifida.

In a public release posted by EurekaAlert!, Dr. Wang is quoted as saying, “We are excited about what we see so far and are anxious to further explore the clinical applications of this research.”

The discovery and development of a treatment for spina bifida was funded by a $5.66 million grant from CIRM. You can read more about that award and spina bifida on a previous blog post linked here.

Gene therapy gives patient a cure and a new lease on life

Pursuing an education can be quite the challenge in itself without the added pressure of external factors. For Brenden Whittaker, a 25 year old from Ohio, the constant trips to the hospital and debilitating nature of an inherited genetic disease made this goal particularly challenging and, for most of his life, out of sight.

Brenden was born with chronic granulomatous disease (CGD), a rare genetic disorder that affects the proper function of neutrophils, a type of white blood cell that is an essential part of the body’s immune system. This leads to recurring bacterial and fungal infections and the formation of granulomas, which are clumps of infected tissue that arise as the body attempts to isolate infections it cannot combat. People with CGD are often hospitalized routinely and the granulomas themselves can obstruct digestive pathways and other pathways in the body. Antibiotics are used in an attempt to prevent infections from occurring, but eventually patients stop responding to them. One in two people with CGD do not live past the age of 40.

In Brenden’s case, when the antibiotics he relied on started failing, the doctors had to resort to surgery to cut out an infected lobe of his liver and half his right lung. Although the surgery was successful, it would only be a matter of time before a vital organ was infected and surgery would no longer be an option.

This ultimately lead to Brenden becoming the first patient in a CGD gene therapy trial at the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center.  The trial, lead by UCLA’s Dr. Don Kohn thanks to a CIRM grant, combats the disease by correcting the dysfunctional gene inside a patient’s blood stem cells. The patient’s corrected blood stem cells are then reintroduced, allowing the body to produce properly functioning neutrophils, rebooting the immune system.

It’s been a little over three years since Brenden received this treatment in late 2015, and the results have been remarkable. Dr. David Williams, Brenden’s treating physician, expected Brenden’s body to produce at least 10 percent of the functional neutrophils, enough so that Brenden’s immune system would provide protection similar to somebody without CGD. The results were over 50 percent, greatly exceeding expectations.

In an article published by The Harvard Gazette, Becky Whittaker, Brendan’s mother, is quoted as saying, ““Each day that he’s free of infection, he’s able to go to class, he’s able to work at his part-time job, he’s able to mess around playing with the dog or hanging out with friends…[this] is a day I truly don’t believe he would have had beyond 2015 had something not been done.”

In addition to the changes to his immune system, the gene therapy has reinvigorated Brenden’s drive for the future. Living with CGD had caused Brenden to miss out on much of his schooling throughout the years, having to take constant pauses from his academics at a community college. Now, Brenden aims to graduate with an associate’s degree in health sciences in the spring and transfer to Ohio State in the fall for a bachelor’s degree program. In addition to this, Brenden now has dreams of attending medical school.

In The Harvard Gazette article, Brenden elaborates on why he wants to go to medical school saying, ” Just being the patient for so long, I want to give back. There are so many people who’ve been there for me — doctors, nurses who’ve been there for me [and] helped me for so long.”

In a press release dated February 25, 2019, Orchard Therapeutics, a biopharmaceutical company that is continuing the aforementioned approach for CGD, announced that six patients treated have shown adequate neutrophil function 12 months post treatment. Furthermore, these six patients no longer receive antibiotics related to CGD. Orchard Therapeutics also announced that they are in the process of designing a registrational trial for CGD.

A new stem cell derived tool for studying brain diseases

Neurological diseases are among the most daunting diagnoses for a patient to receive, because they impact how the individual interacts with their surroundings. Central to our ability to provide better treatment options for these patients, is scientists’ capability to understand the biological factors that influence disease development and progression. Researchers at the Stanford University School of Medicine have made an important step in providing neuroscientists a better tool to understand the brain.

While animal models are excellent systems to study the intricacies of different diseases, the ability to translate any findings to humans is relatively limited. The next best option is to study human stem cell derived tissues in the laboratory. The problem with the currently available laboratory-derived systems for studying the brain, however, is the limited longevity and diversity of neuronal cell types. Dr. Sergiu Pasca’s team was able to overcome these hurdles, as detailed in their study, published in the journal Nature Neuroscience.

A new approach

Specifically, Dr. Pasca’s group developed a method to differentiate or transform skin derived human induced pluripotent stem cells (iPSCs – which are capable of becoming any cell type) into brain-like structures that mimic how oligodendrocytes mature during brain development. Oligodendrocytes are most well known for their role in myelinating neurons, in effect creating a protective sheath around the cell to protect its ability to communicate with other brain cells. Studying oligodendrocytes in culture systems is challenging because they arise later in brain development, and it is difficult to generate and maintain them with other cell types found in the brain.

These scientists circumvented this problem by using a unique combination of growth factors and nutrients to culture the oligodendrocytes, and found that they behaved very similarly to oligodendrocytes isolated from humans. Most excitingly, they observed that the stem cell-derived oligodendrocytes were able to myelinate other neurons in the culture system. Therefore they were both physically and functionally similar to human oligodendrocytes.

Importantly, the scientists were also able to generate astrocytes alongside the oligodendrocytes. Astrocytes perform many important functions such as providing essential nutrients and directing the electrical signals that help cells in the brain communicate with each other. In a press release, Dr. Pasca explains the importance of generating multiple cell types in this in vitro system:

“We now have multiple cell types interacting in one single culture. This permits us to look close-up at how the main cellular players in the human brain are talking to each other.”

This in vitro or laboratory-developed system has the potential to help scientists better understand oligodendrocytes in the context of diseases such as multiple sclerosis and cerebral palsy, both of which stem from improper myelination of brain nerve cells.

This work was partially supported by a CIRM grant.

Targeted treatment for pediatric brain tumors shows promising results

Image of medulloblastoma

Imagine sitting in the doctor’s office and being told the heartbreaking news that your child has been diagnosed with a malignant brain tumor. As one might expect, the doctor states that the most effective treatment option is typically a combination of chemotherapy and radiation. However, the doctor reveals that there are additional risks to take into account that apply to children. Since children’s tiny bodies are still growing and developing, chemotherapy and radiation can cause long-term side effects such as intellectual disabilities. As a parent, it is painful enough to have to watch a child go through chemotherapy and radiation without adding permanent damage into the fold.

Sadly, this scenario is not unique. Medulloblastoma is the most prevalent form of a pediatric brain tumor with more than 350 children diagnosed with cancer each year. There are four distinct subtypes of medulloblastoma, with the deadliest being known as Group 3.

Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) are trying to minimize the collateral damage by finding personalized treatments that reduce side effects while remaining effective. Scientists at SBP are working with an inhibitor known as LSD1 that specifically targets Group 3 medulloblastoma in a mouse model. The study, published in Nature Communications, showed that the drug dramatically decreased the size of tumors grown under the mouse’s skin by shrinking the cancer by more than 80 percent. This suggested that it could also be effective against patients’ tumors if it could be delivered to the brain. The LSD1 inhibitor has shown promise in clinical trials, where it has been tested for treating other types of cancer.

According to Robert Wechsler-Reya, Ph.D., senior author of the paper and director of the Tumor Initiation and Maintenance Program at SBP: “Our lab is working to understand the genetic pathways that drive medulloblastoma so we can find better ways to intervene and treat tumors. This study shows that a personalized treatment based upon a patient’s specific tumor type might be within our reach.”

Dr. Wechsler-Reya’s work on medulloblastoma was, in part, funded by the CIRM (LA1-01747) in the form of a Research Leadership Award for $5,226,049.

Has Regenerative Medicine Come of Age?

Signals logo

For the past few years the Signals blog site –  which offers an insiders’ perspectives on the world of regenerative medicine and stem cell research – has hosted what it calls a “Blog Carnival”. This is an event where bloggers from across the stem cell field are invited to submit a piece based on a common theme. This year’s theme is “Has Regenerative Medicine Come of Age?” Here’s my take on that question:

Many cultures have different traditions to mark when a child comes of age. A bar mitzvah is a Jewish custom marking a boy reaching his 13th birthday when he is considered accountable for his own actions. Among Latinos in the US a quinceañera is the name given to the coming-of-age celebration on a girl’s 15th birthday.

Regenerative Medicine (RM) doesn’t have anything quite so simple or obvious, and yet the signs are strong that if RM hasn’t quite come of age, it’s not far off.

For example, look at our experience at the California Institute for Regenerative Medicine (CIRM). When we were created by the voters of California in 2004 the world of stem cell research was still at a relatively immature phase. In fact, CIRM was created just six years after scientists first discovered a way to derive stem cells from human embryos and develop those cells in the laboratory. No surprise then that in the first few years of our existence we devoted a lot of funding to building world class research facilities and investing in basic research, to gain a deeper understanding of stem cells, what they could do and how we could use them to develop therapies.

Fast forward 14 years and we now have funded 49 projects in clinical trials – everything from stroke and cancer to spinal cord injury and HIV/AIDS – and our early funding also helped another 11 projects get into clinical trials. Clearly the field has advanced dramatically.

In addition the FDA last year approved the first two CAR-T therapies – Kymriah and Yescarta – another indication that progress is being made at many levels.

But there is still a lot of work to do. Many of the trials we are funding at the Stem Cell Agency are either Phase 1 or 2 trials. We have only a few Phase 3 trials on our books, a pattern reflected in the wider RM field. For some projects the results are very encouraging – Dr. Gary Steinberg’s work at Stanford treating people recovering from a stroke is tremendously promising. For others, the results are disappointing. We have cancelled some projects because it was clear they were not going to meet their goals. That is to be expected. These clinical trials are experiments that are testing, often for the first time ever in people, a whole new way of treating disease. Failure comes with the territory.

As the number of projects moving out of the lab and into clinical trials increases so too are the other signs of progress in RM. We recently held a workshop bringing together researchers and regulators from all over the world to explore the biggest problems in manufacturing, including how you go from making a small batch of stem cells for a few patients in an early phase clinical trial to mass producing them for thousands, if not millions of patients. We are also working with the National Institutes of Health and other stakeholders in discussing the idea of reimbursement, figuring out who pays for these therapies so they are available to the patients who need them.

And as the field advances so too do the issues we have to deal with. The discovery of the gene-editing tool CRISPR has opened up all sorts of possible new ways of developing treatments for deadly diseases. But it has also opened up a Pandora’s box of ethical issues that the field as a whole is working hard to respond to.

These are clear signs of a maturing field. Five years ago, we dreamed of having these kinds of conversations. Now they are a regular feature of any RM conference.

The simple fact that we can pose a question asking if RM has come of age is a sign all by itself that we are on the way.

Like little kids sitting in the back of a car, anxious to get to their destination, we are asking “Are we there yet?” And as every parent in the front seat of their car responds, “Not yet. But soon.”

CIRM’s Randy Mills leaving stem cell agency to take on new challenge

Mills, Randy Union Tribune K.C. Alfred

Some news releases are fun to write. Some less so. The one that CIRM posted today definitely falls into that latter group. It announced that CIRM’s President and CEO, Randy Mills, is leaving us to take up the role of President and CEO at the National Marrow Donor Program – NMPD/Be The Match.

It’s a great opportunity for him but a big loss for us.

Be The Match is a non-profit organization that delivers cures to patients in need of a life-saving marrow or cord blood transplant. The organization operates the national Be The Match Registry®—the world’s largest listing of potential marrow donors and donated umbilical cord blood units—matches patients with their marrow donor, educates healthcare professionals and conducts research so more lives can be saved. The organization also recently created a subsidiary—Be The Match BioTherapiesSM—that supports organizations pursuing new life-saving treatments in cellular therapy.

Randy has been at CIRM since April 2014. In that time he has dramatically re-shaped the agency, and, more importantly, dramatically improved the speed with which we are able to fund research. It’s no exaggeration to say that Randy’s drive to create CIRM 2.0 was a radical overhaul of the way we work. It made it easier for researchers to apply to us for funding, made our funding cycles more consistent and the application process simpler – though no less rigorous.

As our CIRM Board Chair Jonathan Thomas said in the news release:

“CIRM has experienced a remarkable transformation since Randy’s arrival. He has taken the agency to a new level by developing and implementing a bold strategic plan, the results of which include an 82% reduction in approval time for clinical trial projects, a 3-fold increase in the number of clinical trials, and a 65% reduction in the time it takes to enroll those trials. The opportunity for Randy to lead a tremendously important organization such as the NMDP/Be The Match is consistent with the values he demonstrated at CIRM, which put the well-being of patients above all else. We shall miss him but know he will do great things at NMDP/Be The Match.”

From a personal perspective, what most impressed me about Randy was his willingness to involve every person in the agency in changing the way we work. He could easily have come in and simply issued orders and told people what to do. Instead he invited every person at CIRM to sit in on the meetings that were shaping the new direction we took. You didn’t have to go, but if you did you were expected to offer thoughts and ideas. No sitting idly by.

Those meetings not only changed the direction of the agency, they also re-energized the agency. When people feel their voice is being heard, that their opinion has value, they respond by working harder and smarter.

The CIRM of today has the same mission as always – accelerating stem cell treatments to patients with unmet medical needs – but the people working here seem to have a renewed commitment to making that mission a reality.

Randy brought to CIRM energy and a renewed sense of purpose, along with some truly terrible jokes and a strange conviction that he could have been a great rock and roll drummer (suffice to say he made the right career choice when he went into research).

He changed us as an agency, for the better. We shall miss him, but know he will do great things in his new role at NMDP/Be The Match and we wish him success in his new job, and his family great joy in their new home.

Randy will be with us till the end of June and starting July 1st Dr. Maria Millan will take on the role of interim President and CEO.

 

 

 

The power of the patient’s voice: how advocates shape clinical trials and give hope to those battling deadly diseases

stack-family-2017-3046-12

The Stack family: L to R Alex, Natalie, Nancy & Jeff

Tennis great Martina Navratilova was once being interviewed about what made her such a great competitor and she said it was all down to commitment. When pressed she said “the difference between involvement and commitment is like ham and eggs; the chicken is involved but the pig is committed.”

That’s how I feel about the important role that patients and patient advocates play in the work that we do at CIRM. Those of us who work here are involved. The patients and patient advocates are committed. This isn’t just their life’s work;  it’s their life.

I was reminded of that last week when I had the privilege of talking with Nancy Stack, the Patient Representative on a Clinical Advisory Panel (CAP) we have created for a program to treat cystinosis. She has an amazing story to tell. But before we get to that I have to do a little explaining.

Cystinosis is a rare disease, affecting maybe only 2,000 people worldwide, that usually strikes children before they are two years old and can lead to end stage kidney failure before their tenth birthday. Current treatments are limited, which is why the average life expectancy for someone with this is only around 27 years.

When we fund a project that is already in, or hoping to be in, a clinical trial we create a CAP to help assist the team behind the research. The CAP consists of a CIRM Science Officer, an independent scientific expert in this case for cystinosis, and a Patient Representative.

The patient’s voice

The Patient Representative’s role is vital because they can help the researchers understand the needs of the patient and take those needs into account when designing the trial. In the past, many researchers had little contact with patients and so designed the trial around their own needs. The patients had to fit into that model. We think it should be the other way around; that the model should fit the patients. The Patient Representatives help us make that happen.

Nancy Stack did just that. At the first meeting of the CAP she showed up with a list of 38 questions that she and other families with cystinosis had come up with for the researchers. They went from the blunt – “Will I die from the treatment” – to the practical –  “How will children/teens keep up with school during the process?” – and included a series of questions from a 12-year old girl with the disease – “Will I lose my hair because I’ve been growing it out for a long time? Will I feel sick? Will it hurt?”

Nancy says the questions are not meant to challenge the researcher, in this case U.C. San Diego’s Stephanie Cherqui, but to ensure that if the trial is given the go-ahead by the US Food and Drug Administration (FDA) that every patient who signs up for it knows exactly what they are getting into. That’s particularly important because many of those could be children or teenagers.

Fully informed

“As parents we know the science is great and is advancing, but we have real people who are going to go through this treatment so we have a responsibility to know what will it mean to them. Patients know they could die of the disease and so this research has real world implications for them.”

“I think without this, without allowing the patients voice to be heard, you would have a hard time recruiting patients for this kind of clinical trial.”

Nancy says not only was Dr. Cherqui not surprised by the questions, she welcomed them. Dr. Cherqui has been supported and funded by the Cystinosis Research Foundation for years and Nancy says she regards the patients and patient advocates as partners in this journey:

“She knows we are not challenging her, we’re supporting her and helping her cover every aspect of the research to help make it work.”

Nancy became committed to finding a cure for cystinosis when her daughter, Natalie, was diagnosed with the condition when she was just 7 months old. The family were handed a pamphlet titled “What to do when your child has a terminal disease” and told there was no cure.

Birthday wish

In 2003, on the eve of her 12th birthday, Nancy asked Natalie what her wish was for her birthday. She wrote on a napkin “to have my disease go away forever.” The average life expectancy for people with cystinosis at that point was 18. Nancy told her husband “We have to do something.”

They launched the Cystinosis Research Foundation and a few weeks later they held their first fundraiser. That first year they raised $427,000, an impressive amount for such a rare disease. Last year they raised $4.94 million. Every penny of that $4.94 million goes towards research, making them the largest funders of cystinosis research in the world.

“We learned that for there to be hope there has to be research, and to do research we needed to raise funds. Without that we knew our children would not survive this disease.”

Natalie is now 26, a graduate of Georgetown and USC, and about to embark on a career in social work. Nancy knows many others are not so fortunate:

“Every year we lose some of our adults, even some of our teens, and that is unbelievably hard. Those other children, wherever they may live, they are my children too. We are all connected to each other and that’s what motivates me every day. Having a child with this disease means that time is running out and there must be a commitment to work hard every day to find a cure, and never giving up until you do.”

That passion for the cause, that compassion for others and determination to help others makes the Patient Representative on the CAP so important. They are a reminder that we all need to work as hard as we can, as fast as we can, and do everything we can to help these trials succeed.

And we are committed to doing that.

Stem Cell Profiles in Courage: Brenden Whittaker

brenden-and-dog

Brenden Whittaker: Photo Colin McGuire

It’s not often you meet someone who says one of their favorite things in the world is mowing the lawn. But then, there aren’t many people in the world like Brenden Whittaker. In fact, as of this writing, he may be unique.

Brenden was born with severe chronic granulomatous disease (x-CGD), a rare genetic disorder that left him with an impaired immune system that was vulnerable to repeated bacterial and fungal infections. Over 22 years Brenden was in and out of the hospital hundreds of times, he almost died a couple of times, and lost parts of his lungs and liver.

Then he became the first person to take part in a clinical trial to treat x-CGD. UCLA researcher Don Kohn had developed a technique that removed Brenden’s blood stem cells, genetically re-engineered them to correct the mutation that caused the disease, and then returned those stem cells to Brenden. Over time they created a new blood system, and restored Brenden’s immune system.

He was cured.

We profiled Brenden for our 2016 Annual Report. Here’s an extended version of the interview we did with him, talking about his life before and after he was cured.

brenden_stories_of_hope

Brenden with a CIRM Game Ball – signed by everyone at CIRM

Brenden’s story:

I still think about it, my disease, every few days or so and it’s weird because in the past I was sick so often; before this year, I was sick consistently for about 5 years and going to doctor’s appointments 2 or 3 times a week and being in the hospital. So, it’s weird having a cough and not having to be rushed to the ER, not having to call someone every time the smallest thing pops up, and not having to worry about what it means.

It’s been good but it’s been weird to not have to do that.  It’s a nice problem to have.

What are you doing now that you didn’t do before?

Cutting the grass is something I couldn’t do before, that I’ve taken up now. Most people look at me as if I’m crazy when I say it, but I love cutting grass, and I wasn’t able to do it for 22 years of my life.

People will complain about having to pick up after their dog goes to the bathroom and now I can follow my dog outside and can pick up after her. It really is just the little things that people don’t think of. I find enjoyment in the small things, things I couldn’t do before but now I can and not have to worry about them.

The future

I was in the boy scouts growing up so I love camping, building fires, just being outdoors. I hiked on the Appalachian Trail. Now I’ll be able to do more of that.

I have a part time job at a golf course and I’m actually getting ready to go back to school full time in January. I want to get into pre-med, go to medical school and become a doctor. All the experience I’ve had has just made me more interested in being a doctor, I just want to be in a position where I can help people going through similar things, and going through all this just made me more interested in it.

Before the last few months I couldn’t schedule my work more than a week in advance because I didn’t know if I was going to be in the hospital or what was going on. Now my boss jokes that I’m giving him plans for the next month or two. It’s amazing how far ahead you can plan when you aren’t worried about being sick or having to go to the hospital.

I’d love to do some traveling. Right now most of my traveling consists of going to and from Boston (for medical check-ups), but I would love to go to Europe, go through France and Italy. That would be a real cool trip. I don’t need to see everything in the world but just going to other countries, seeing cities like London, Paris and Rome, seeing how people live in other cultures, that would be great.

Advice for others

I do think about the fact that when I was born one in a million kids were diagnosed with this disease and there weren’t any treatments. Many people only lived a few years. But to be diagnosed now you can have a normal life. That’s something all on its own. It’s almost impossible for me to fathom it’s happening, after all the years and doctor’s appointments and illnesses.

So, for people going through anything like this, I’d say just don’t give up. There are new advances being made every day and you have to keep fighting and keep getting through it, and some day it will all work out.
