FDA Approves Test of Combined Stem Cell and Gene Therapy for ALS

FDA Approves Test of Combined Stem Cell and Gene Therapy for ALS

Regenerative medicine investigators at the Cedars-Sinai Medical Center have received U.S. Food and Drug Administration (FDA) approval to test a novel combination stem cell-gene therapy they’ve developed to stall amyotrophic lateral sclerosis (ALS) progression. Enrollment in the trial is expected to commence soon.

Also known as Lou Gehrig’s disease, ALS is a neurological disorder that attacks muscle-controlling nerve cells motor neurons in the brain, brainstem and spinal cord, causing progressive paralysis. As motor neurons die, patients lose their ability to initiate and control muscle movement, leading to paralysis and eventually death, usually within five years of diagnosis. Because there are no effective treatments for ALS, leaving patients reliant on only medications that help alleviate symptoms such as muscle spasms, or mechanical breathing aid devices, this upcoming clinical trial is regarded as particularly significant.

The FDA testing approval will allow 18 ALS patients to receive a new investigational drug within a few months once the study begins at the Cedars-Sinai Board of Governors Regenerative Medicine Institute. It reportedly will be the first clinical trial to test the safety of this type of therapy, which has been developed with the intention of preserving ALS patients’ leg mobility.

The Cedars-Sinai Board of Governors Regenerative Medicine Institute’s focus is on regenerative medicine, a developing field that aims to restore function in diseased or aged tissues by either revitalizing existing cells or transplantation of new cells. The theory is that revitalization could occur through introduction of powerful growth factors to the body, or by stimulating immune system function in ways that enhance cell survival.

Consequently, stem cells are of particular interest to regenerative medicine researchers. These cells, found deep within most adult body tissues, often are difficult to manipulate or expand outside the body. Stem cells in bone marrow are responsible for blood production and play a major role in immune defense activity, while other stem cells may be associated with certain cancers, with biology that scientists suggest may lead to promising new techniques for reducing tumor growth.

Stem cells found in the adult heart and can be manipulated and grown outside the body then transplanted back into the donor patient, while embryonic stem cells can be isolated from human embryos (hES cells) and propagated to enormous numbers in the laboratory while remaining “pluripotent” — capable of generating any human body tissues.

Stem cells from the adult human body categorized as induced pluripotent stem (iPS) cells also have recently been reprogrammed to an embryonic stem cell state, and are important for regenerative medicine because they can be derived from a patient and turned into any type of body tissue, which then can be used as a source of autologous cells for repair while avoiding immune rejection issues. Importantly, use of iPS cells avoids ethical issues associated with collection and destruction of human embryos.

“Any time you’re trying to treat an incurable disease, it is a long shot, but we believe the rationale behind our new approach is strong,” Clive Svendsen, PhD, a professor of Medicine and of Biomedical Sciences, and director of the Cedars-Sinai Board of Governors Regenerative Medicine Institute, said in a press release. Svendson has spent a dozen years developing a new regenerative medicine approach, funded by a $16.8 million grant from the San Francisco-based California Institute for Regenerative Medicine (CIRM) and outlined in a 4,600-page application to the FDA.

“This is a highly innovative approach to a disease that has mystified medicine for generations,”  Shlomo Melmed, MD, Cedars-Sinai executive vice president for Academic Affairs and dean of the medical faculty said. “The combination of cutting-edge stem cell science, developing a new device to inject the cells, our outstanding research laboratories and the direct involvement of neuroscientists, neurosurgeons and neurologists, made this CIRM-funded project possible,” he said.

Trial participants will be recruited from the ALS Clinic at Cedars-Sinai, with the trial to be led by Robert Baloh, MD, PhD, and Peggy Allred, PT, DPT. The neurosurgical team will be led by J. Patrick Johnson, MD, MS, of the Cedars-Sinai Spine Center, whose multidisciplinary team includes orthopaedists, neurosurgeons, pain management and conservative care specialists and spine nurses.

Patients eligible to be considered as participants the trial must be experiencing ALS-caused leg weakness, with stem cell implantations to be conducted during five-hour surgical procedures in which a neurosurgeon will remove a piece of bone in the lumbar region of the patient’s lower back and inject stem cells directly into an area of the patient’s spinal cord that governs movement on only one side of the body. The surgeon will employ an investigational device developed specifically for this trial, and neither the patients nor the physicians caring for them will know which side has received the stem cells.

“We will follow the patients for a year and measure the strength in each leg,” Svendsen said. “In ALS, usually the legs lose strength at the same time. This is a small safety trial to ensure the cells releasing GDNF do not have any negative effects on leg function. If safe, we plan a larger future trial to see if this therapy can improve strength in the treated leg.”

    Please sign my son up he is 41 years old he has had als for almost 2 years. He goes to the VA .hospital in Tampa fl.His name is Scott Whitmire.

  2. David Wait says:

    I am a 67 year old male from Canada. Canada has no treatment process for this disease.
    I am 2 months past my diagnosis which by the way took a year to receive the final diagnosis.
    My issues at this time are speech slur and upper right arm muscle loss of use.
    Please lets try to speed up the stemcell treatment process and allow us to have some hope.

    Thank you

    • Tim Bossie says:

      We are sorry to hear about your struggle with ALS and hope that there is some speed to the research and hopeful approval of this treatment.

  3. Angela parker says:

    I may be newly diagnosed at Mayo Jacksonville. In good Heath began with fasciculations and in good health. Beginning stages. Wan to be in clinical trials to see the if the earlier start better the chances.

  4. Alireza tabrizi says:

    I am suspected to ALS and 28 years old.Can you tell aBout the progression of the trial? Any success during the process?i also can be a part of this trial.

  5. Rebecca Scannell says:

    My mom has recently been diagnosed with ALS. Has the selection for candidates for this trial already come to pass?

  6. Phyllis Maria says:

    My husband was diagnosed with ALS 15 years ago and is still holding on. It seems like since he has had it so long that no one wants to do anything. My thinking is that someone would want to help a man who has lived with this diagnosis for 15 years. He is totally bedridden and on a ventilator but looks great. At one point early on they thought of changing his diagnosis but didn’t. Certainly hope that you can HELP.

    • Tim Bossie says:

      We are all very sorry for your husband’s condition and struggle. It does seem that when someone lives a long time with this disease that people forget about them. Hoping that some rapid advancements with stem cell therapy can help.

    • Aziz Khan says:

      I am 60 years old and diagnosed recently with ALS. Please include me in the clinical trial. My neurologists would be able to provide all the data needed for this study. Thank you.

  7. Mehboob Sadiq says:

    I have ALS, have speech, swallow problem, have no appetite and losing weight, have weakness in palms and arms. please include me in your research trial. Thanks

  8. Ken Barker says:

    I just recently contracted ALS. My roommate was in the gulf war and we spent the last 5 months in a one bedroom apt. I have the symptoms and I am 61 years old and super healthy. Please sign me up!

  9. lucy artukovich says:

    my father is 56 years old. and just got diagnosed with Als at the mayo clinic. My dad has always been our rock. I am his oldest daughter and he has 5 other children and 5 new grand kids. He is withering away and doesn’t go to work anymore, doesn’t do anything but sit on the couch. we don’t know how to handle this bc he has always been a hard working man with his own business. His grandfather died from the same thing. we are remaining positive and hoping he can get into a stem cell research trial anywhere if possible. where do we look? who do we call? how can we try to get him on some kind of a list? please help! thank you …

  10. Wally Berger says:

    My son is 34 years old and has just been diagnosed with ALS. Slurred speech, mussel twitches and weakness in my left leg & arm. Please consider me for your trial. I am married with 2 young kids.

  11. Daniele R Crelin says:

    I would like you to consider including my husband in your trial. He was diagnosed 5 months ago. He was 60 at the time and has never had any health issues prior to this. He currently has weakness in his left leg, but is still able to walk and still goes to work. He rides his exercise bike and is incredibly determined. We have family in LA, so we could travel if you are interested in including him.
    I wish you all the luck in the world and thank you for creating hope in a situation where there is little.
    All I can say is…please hurry!

  12. dacian herbei says:

    Dear Sir.
    I hope my letter finds you healthy.
    My father was diagnosed with ALS and I would like to ask when will be the studies of the trial made available.
    Could you recommend me similar trials or could you include my father in this trial?
    best regards,
