UCI team gets $5 million to create stem cell treatment for Huntington's disease

Posted: March 27, 2015 at 5:45 pm

Irvine, Calif., March 26, 2015 -- Leslie Thompson of the Sue & Bill Gross Stem Cell Research Center at UC Irvine has been awarded $5 million by the California Institute for Regenerative Medicine to continue her CIRM-funded effort to develop stem cell treatments for Huntington's disease.

The grant supports her next step: identifying and testing stem cell-based treatments for HD, an inherited, incurable and fatal neurodegenerative disorder. In this project, Thompson and her colleagues will establish an HD therapy employing human embryonic stem cells that can be evaluated in clinical trials.

Over the past seven years, Thompson, a UCI professor of psychiatry & human behavior and neurobiology & behavior, and her team have used CIRM funding to produce stem cell lines "reprogrammed" from the skin cells of individuals carrying the Huntington's genetic mutation in order to study the disease. In addition, they conducted basic and early-stage transitional studies to develop a stem cell-based technique to treat areas of the brain susceptible to HD.

"These stem cells offer a possible long-term treatment approach that could relieve the tremendous suffering experienced by HD patients and their families," said Thompson, who's also affiliated with UCI's Institute for Memory Impairments and Neurological Disorders (UCI MIND). "We appreciate CIRM and the millions of people in the state of California for generously supporting breakthrough stem cell research."

With this award, CIRM has granted Thompson $10.3 million for her HD work. Overall, UCI has received $105 million from the state-funded agency.

Thompson said that her group has identified a highly promising neural stem cell line that shows disease-modifying activity in HD mice. These neural stem cells were grown from human embryonic stem cells at UC Davis. The researchers also will conduct essential preclinical efficacy and safety studies in HD mice with these cells.

Over the span of the 2-year grant, Thompson said, the goal is to finalize work that will lead to a pre-investigational-new-drug meeting with the Food & Drug Administration and a path forward for clinical trials with the neural stem cells.

"This investment will let us further test the early promise shown by these projects," said Jonathan Thomas, chair of the CIRM governing board. "Preclinical work is vital in examining the feasibility, potential effectiveness and safety of a therapy before we try it on people. These projects all showed compelling evidence that they could be tremendously beneficial to patients. We want to help them build on that earlier research and move the projects to the next level."

HD is a devastating degenerative brain disorder with no disease-modifying treatment or cure. Current approaches only address certain symptoms of HD and do not change its course.

Blood test uses human stem cells to predict severe drug reactions

Posted: March 26, 2015 at 6:51 pm

Scientists have developed a blood test using human stem cells that predicts whether new drugs will cause severe side effects. The test, which only requires blood from a single donor, could help prevent catastrophic inflammatory reactions known as a cytokine storm in people participating in drug trials.

"As biological therapies become more mainstream, its more likely that drugs being tested on humans for the first time will have unexpected and potentially catastrophic effects," says Professor Jane Mitchell from the National Heart and Lung Institute at Imperial College London, who led the study. "Weve used adult stem cell technology to develop a laboratory test that could prevent another disaster like the TGN1412 trial."

In 2006 six healthy young men were hospitalized with multiple organ failure after experiencing a cytokine storm as a result of taking part in the first tests in humans of the drug TGN1412.

Tests on human cells are essential because biological therapies, or "biologics" (such as the cancer drugs Herceptin and Avastin), use antibodies which are specific to humans. They can cause severe reactions, such as a cytokine storm, that dont occur in animal studies.

Cytokine storm reactions are difficult to predict using tests where just one cell type is used because they require interactions between blood cells and endothelial cells (the cells which form the lining of blood vessels).

However, because endothelial cells are located deep within the body and are difficult to access, they are normally only grown from tissue removed in surgery, during post-mortem, or from umbilical vessels after birth. Current testing is therefore performed on endothelial cells from one donor and white blood cells from a different donor.

This in itself can present issues; when cells from two different donors are used, one may have an immune reaction to the other, meaning the body is already primed for inflammation before the drug is added, potentially leading to false test results.

The Imperial College London team has developed a new method of testing which requires blood from only one donor, making it far more reliable.

By taking stem cells from the blood of a volunteer and using them to grow endothelial cells in a dish, a process which takes seven to 20 days, then adding them to the donor's white blood cells, they have recreated the unique conditions found in the donor's blood vessels. When the researchers added TGN1412 to the test tube, the cells released a cytokine storm, just as would happen inside the body.

The scientists are now developing an off-the-shelf kit to enable drug companies to use the test on a large scale.

UK must address regulatory and funding issues to realise promise of regenerative medicine, says expert

Posted: March 26, 2015 at 6:51 pm

Life sciences specialist Helen Cline of Pinsent Masons, the law firm behind Out-Law.com, said that regenerative medicine is the "future of medicine" and welcomed proposals to make navigating the regulatory environment easier.

A new report published by the Regenerative Medicine Expert Group (RMEG) (40-page / 4.17MB PDF) sets out what additional steps are necessary to help researchers develop and clinicians utilise technologies that improve the human body's ability to repair itself. The RMEG is tasked with developing an NHS regenerative medicine strategy.

In its report, RMEG defined 'regenerative medicine' as "methods that replace or regenerate human cells, tissues or organs in order to restore or establish normal function".

"The nature of regenerative medicine research involves creating personalised precision therapies that may provide a cure rather than merely alleviating symptoms but there is often a high up-front cost associated with these individualised therapies which raises challenges around evaluation, funding and adoption," Cline said.

Cline said that "unnecessary, excessively complex or burdensome regulation" together with "unclear evaluation and funding pathways could stifle the promise of regenerative medicine". However, she said moves to streamline regulation to enable innovation must not "put patients at risk of harm and damage the reputation of this field of research at a crucial point in its history".

"Regulation in the area of regenerative medicines is complex, reflecting the nature of the technologies and their risks," Cline said. "For example, in the UK there are four regulatory bodies each regulating distinct aspects of the development of regenerative medicine under different pieces of legislation."

Cline said there have already been steps taken towards the "streamlining of regulatory advice", with a single point of access for advice on regenerative medicine rules available from the Innovation Office within the Medicines and Healthcare Products Regulatory Agency (MHRA).

Regulators have also collaborated on providing guidance on regenerative medicines issues, including developing the UK Stem Cell Tool Kit to provide clear guidance on the regulatory pathways that must be followed in developing a regenerative product derived from stem cells, Cline said.

However, the RMEG's report said that "further steps are needed to ensure that standardisation of processes, and streamlined regulation, are guiding principles in advancing regenerative medicine".

The RMEG also identified funding issues as a barrier to the growth of regenerative medicines, and called on the UK government and industry to come together to develop "an innovative business model that supports the early adoption of regenerative medicines". It also called for reviews to be carried out on "the funding for excess treatment costs for cell therapy trials" with the aim of finding "a mechanism to ensure that meeting of these costs is not a barrier to clinical trials or the early adoption of technologies".

No stem cell treatment for public servant's dodgy knee

Posted: March 26, 2015 at 6:48 pm

A federal public servant has lost a legal bid to have taxpayers pay for experimental stem cell treatment on his dodgy knees.

The Administrative Appeals Tribunal has knocked back an appeal by Customs officer Vic Kaplicas to force insurer Comcare to pay $13,400 for the new treatment, instead saying he could have a tried-and-tested double knee replacement.

But the 49-year-old border official says he worries he cannot pass his department's fitness tests if he undergoes the knee replacements, which will leave him unable to run.

The former triathlete, who had to give up his sport because of his bad knees, said he was keen to avoid the "radical but effective" replacements for as long as possible.

Mr Kaplicas hurt his left knee working at Sydney's Mascot Airport in 2000, then injured his right knee 10 years later at Kingsford-Smith.

He managed the pain in his knees, which have since developed osteoarthritis, for years using over-the-counter painkillers, physio, exercises and injections but Mr Kaplicas' doctors say a more permanent solution is now needed.

In June 2012, Sydney knee specialist Sam Sorrenti asked Comcare to pay for bilateral knee stem cell assisted arthroscopic surgery for Mr Kaplicas.

The cost of the procedure was estimated at $13,464.00 for arthroscopy, stem cell harvesting and injection, and a "HiQCell procedure".

Dr Sorrenti said the knee replacements were not a good idea for a man of Mr Kaplicas' age, arguing the new knees would last 15 years at best, were intended for older people who are less concerned with physical activity, and left no further options.

Lung Institute Announces New Treatment with Bone Marrow

Posted: March 26, 2015 at 6:45 pm

Tampa, FL. (PRWEB) March 26, 2015

This month, the Lung Institute has started treating people suffering from chronic lung diseases with stem cells extracted from their bone marrow. This treatment protocol is added to the two other treatment options offered by the Lung Institute: venous (blood-derived) and adipose (fat-derived) stem cell therapy.

The bone marrow and adipose treatments offer the highest concentration of stem cells and allow for the cells to be reintroduced directly into the lungs through a nebulizer. Given this added benefit, most patients in the past opted to receive the adipose treatment over venous. However, many patients have other medical conditions that preclude them from choosing the adipose treatment. Since the number of stem cells harvested from a bone marrow procedure matches that of the adipose procedure, patients that have previously only qualified for the venous procedure are now eligible for a treatment option that produces the highest chance of success.

Patients are often surprised by the simplicity of these minimally invasive procedures, but with cutting-edge technology and the patient-centric clinical team at the Lung Institute, patients can rest assured that they are in good hands. Throughout the entire treatment process, patients have the opportunity to get any questions immediately answered by our knowledgeable medical staff. The Lung Institute clinical team remains in contact with patients after treatment and works together with the patients physician and pulmonologist to create a strong support system for the patient.

About the Lung Institute At the Lung Institute, we are changing the lives of hundreds of people across the nation through the innovative technology of regenerative medicine. We are committed to providing patients a more effective way to address pulmonary conditions and improve their quality of life. Our physicians, through their designated practices, have gained worldwide recognition for the successful application of revolutionary minimally invasive stem cell therapies. With over a century of combined medical experience, our doctors have established a patient experience designed with the highest concern for patient safety and quality of care.
