Gene Therapy 3.0: Rise and fall and rise again of gene therapy–For real this time?
Posted on: 18 December 2014, source: Genetic Literacy Project
Gene therapy is back in the news, and in a big way as regular readers of the GLP would know. Studies involving the use of gene therapy are showing promising results for the cure of blood disorders, ‘bubble boy’ disease and HIV among others. Industry interest has also picked up and as positive results from clinical trials roll in, the market suddenly appears bullish on the future. But are we seeing enough to suggest that the technology is promising enough to make a major contribution to public health? Why does gene therapy have to be ‘back’ in the first place?
We offer a quick recap here, but for a more detailed read on the rise and fall (and rise again) of gene therapy, read this excellent narrative by Carl Zimmer in Wired or this comprehensive feature by Laura Cassiday in Nature. Things looked bright for gene therapy in the 90s when it promised to be a revolution that would let us move from just treating genetic diseases to curing them permanently. The big question surrounding gene therapy had always been how to effectively deliver the correct form of the gene into cells.

Regulatory landscape of advanced-therapy medicinal products
Posted on: 14 December 2014, source: lexology.com
Advanced therapy medicinal products (ATMPs) are a category of innovative products comprising gene-therapy medicinal products (GTMPs),somatic cell-therapy medicinal products (sCTMP) and tissue-engineered products (TEPs). The main therapeutic areas are oncology and regenerative medicine, particularly in the field of cardiovascular conditions and haematology. Yet despite the harmonising EU legislation which has been in place since 2008, few products have reached the market in commercial form. In 2014 the European Commission issued a report on the implementation of ATMP legislation to date. On June 30 2014 the European Medicines Agency Committee for Advanced Therapies announced a public consultation on its revised guidance for ATMP classification. The consultation ended on October 31 2014.

Correcting the genetic error in sickle-cell disease might be as simple as amending text
Posted on: 15 November 2014, source: Nature
Tiny changes in DNA can have huge consequences. For years, scientists have been trying to 'fix' these mutations in the hope of treating and potentially curing some of humanity's most devastating genetic diseases. After some tragic early setbacks (see Nature 420, 116–118; 2002), techniques that allow precise genetic manipulation have created a surge of research.
Although most existing treatments for genetic diseases typically only target symptoms, genetic manipulation or 'gene therapy' goes after the cause itself. The approach involves either inserting a functional gene into DNA or editing a faulty one that is already there, so the conditions most likely to prove curable are those caused by a single mutation. Sickle-cell disease is a perfect candidate: it is caused by a change in just one amino acid at a specific site in the β-globin gene. This results in the production of abnormal haemoglobin proteins that cause the red blood cells that house them to twist and become sickle shaped. The distorted cells get sticky, adhere to each other and block blood vessels, preventing oxygenated blood from flowing through

No-frills coats set a trend for designer viruses
Posted on: 28 August 2014, source: Chemistry World
Dutch scientists have built a simple model of viruses’ protective coats in an attempt to create viral mimics that could fight diseases, as opposed to causing them. Rather than copying natural proteins, Renko de Vries from Wageningen University and his team designed and built a three-part protein from scratch that self-assembles around DNA.
‘The protein is exceedingly simple in its primary and secondary structure, yet captures the essence of self-assembly for the tobacco mosaic virus,’ de Vries tells Chemistry World. This knowledge could enable superior vehicles for getting DNA and RNA into cells, for example for gene therapy, and templates for improved DNA machines. ‘You could probably do the same with supramolecular chemistry,’ de Vries adds, ‘but the protein approach has the beauty that you can expand in the direction of synthetic biology.’

Gene correction technique could revolutionise treatment
Posted on: 6 August 2014, source: The Independent
Scientists have performed a “seamless” correction to a faulty gene behind an inherited form of anaemia using a revolutionary new technique in genome editing that could transform the treatment of many genetic diseases. Two mutations in the haemoglobin gene of a patient with beta thalassemia – which can cause severe anaemia – were corrected without any errors using the Crispr technique of genome editing, the researchers said. The experiment involved converting the patient’s skin cells into stem cells in the laboratory so that the faulty gene could be corrected before the stem cells were allowed to mature into red blood cells. Without the genome correction, the red cells would have become deformed and sickle-shaped as a result of the defective haemoglobin gene.

A new technology that allows genes to be injected into hearts with damaged electrical systems may replace the need for pacemaker implants in humans in the future. In the United States alone, there are more than 500,000 patients that get pacemaker implants annually. When the batteries on the Pacemakers run out in seven to 10 years, another surgery is required to implant a new device.

Renewed hope for gene therapy in rare disease
Posted on: 1 July 2014, source: European Research Media Center
New virus serotypes are safely used as ‘DNA transporters’ to successfully deliver genes to deficient cells. Between 30 and 40 million people in Europe suffer from rare diseases—many of them children. As most of these diseases have genetic origins, gene therapy is a major hope for their future cure. Until now, however, there have been very few successful trials. Now, the EU-funded project AIPGENE, due to be completed in 2014, may have made significant progress in a gene therapy approach.
The project focussed on the genetic liver disorder, Acute Intermittent Porphyria (AIP). Through an early stage clinical trial, in phase I, it demonstrated the viability of a new approach, based on a so-called, adeno-associated vector (AAV). This is a ‘DNA transporter’ derived from a type of virus and carries the therapeutic gene to liver cells, known as hepatocytes.

NIH Will No Longer Require Special Review for U.S. Gene Therapy Trials

In a milestone for the field of gene therapy, the National Institutes of Health (NIH) will no longer subject all proposed gene therapy clinical trials to review by a special federal advisory committee. “Given the progress in the field, I am confident that the existing regulatory authorities can effectively review most gene transfer protocols and that a streamlined process will reduce duplication and delays in getting gene transfer trials initiated,” said NIH Director Francis Collins in a statement today. Instead, the 40-year-old Recombinant DNA Advisory Committee (RAC) will review only a few trials that pose special risks.

Gene therapy injections: Future obesity cure?
Posted on: 14 May 2014, source: MetroNews
An injection that promises to end obesity seems like the type of claim found only on obnoxious flashing web ads, but it’s entirely plausible that one day we will be able to treat this common problem with just the prick of a needle, according to Jason Dyck, a researcher at the University of Alberta. Two years ago, Dyck and his colleagues published a paper in the journal Nutrition and Diabetes that concluded an injectable adiponectin gene therapy reduced fat and improved insulin sensitivity in mice, despite the fact the test animals were being fed a high-fat diet.

FDA Grants Breakthrough Status to Gene Therapy for First Time
Posted on: 11 April 2014, source: Bio-ITWorld
Celladon today became the first company to receive breakthrough status for a gene therapy treatment in development. The treatment, MYDICAR, is intended to reduce the risk of heart failure in patients with a deficiency of the enzyme SERCA2a. The FDA made its decision to grant breakthrough status to MYDICAR on the basis of Celladon's Phase 1 trial of 39 systolic dysfunction patients. The study reported that subjects receiving high doses of MYDICAR experienced fewer heart failure events than subjects given a placebo, by a factor of more than 80%, and that this reduction was sustained for three years after treatment. No safety issues were reported in this initial trial. Breakthrough status, which is reserved for treatments targeting life-threatening diseases that show significant improvements over the standard of care, allows closer communication with the FDA and potentially an accelerated approval process.

Gene therapy promising in Parkinson's patients
Posted on: 14 January 2014, source: BioNews
Patients in a clinical trial to treat Parkinson's disease with a form of gene therapy have showed signs of significant improvements in their motor-function, according to a report published in the Lancet. Fifteen advanced-stage Parkinson's patients (three from the UK and 12 from France) were followed up a year after being injected with low, mid and high doses of a modified virus containing genes required for brain cells to produce dopamine, as part of the phase I/II study. A lack of dopamine causes patients with Parkinson's to experience tremors and difficulty in coordinating their movement. The researchers observed that after receiving the treatment the patients' scores on movement tests improved on average by 30 percent. The patients also reported having a better quality of life. Although the patients showed some side effects, overall the treatment was found to be safe and no serious side effects were observed.

Explainer: what is gene therapy?
Posted on: 28 November 2013, source: Science Alert
Every now and again you might read about gene therapy and efforts to correct serious genetic diseases. But I’m betting that very few readers have had gene therapy, nor have they ever met anyone who has, nor will they ever meet that many. The reasons are simple – while these procedures are possible in theory, in practice, it has proved remarkably difficult to insert new genetic materials into human patients and ensure that the new genes are sustainably expressed. The difficulties encountered highlight the fact that we do not yet have enough fundamental knowledge about gene transfer and control. And what’s more, gene therapy is hugely expensive.

Q&A: Gene Therapy the Fix for Faulty DNA
Posted on: 27 November 2013, source: ModVive.com
Inside (almost) all of our cells are 23 pairs of chromosomes, long strands of DNA that are packaged tightly together. Each chromosome houses hundreds of genes, each of which is the blueprint for at least one protein. Little messengers called mRNA make copies of the gene blueprints, edits them and carry them to “builders” called ribosomes. The ribosomes read the copy and translate it into long chains of amino acids that are then folded into unique shapes. These globs of amino acids are proteins, that travel throughout our entire body and are in some way vital for everything that happens inside of us. For example, helicase and chromatin are proteins essential to cell division, what allows us to grow and heal, and immunoglobulin, also called antibodies, protect us from infections.

Gene therapy repairs heart attack damage
Posted on: 29 August 2013, source: BioNews
Researchers have concocted a 'gene cocktail' that may help to turn scar tissue into functioning cardiac cells after a heart attack. Scar tissue often forms following a heart attack in the area that was most affected. The result is a decreased ability of the heart to beat properly and can eventually lead to heart failure. The scientists, from the Gladstone Institutes in San Francisco, USA, are working with cells called fibroblasts, which make up about half of all heart cells. They are aiming to reprogram the function of these fibroblasts from primarily providing structural support to beating heart cells by injecting a cocktail of genes.

First Gene Therapy For Rett Syndrome, An Autism Spectrum Disorder
Posted on: 21 August 2013, source: Medical Daily
Scientists in Oregon have developed a new gene therapy for Rett Syndrome, the most disabling of the autism spectrum disorders. Field-tested in mice, it is the first therapy to reverse the course of the disorder in a fully symptomatic model, which represents an important step towards clinical application. Nearly one in 10,000 kids are born each year with Rett syndrome. Neurological and behavioral features, like loss of speech, immobility, and seizures, typically appear after six months of age. The most frequent cause is the mutation of an X chromosome gene called MECP2, which explains why girls are primarily affected by the condition.

Posted on: 14 July 2013, source: Science 2.0
An international team that developed a new gene therapy approach to treatment of Wiskott-Aldrich Syndrome, a fatal inherited form of immunodeficiency has reported results. Wiskott-Aldrich Syndrome is a disorder that weakens the body's immune system. It is caused by a mutation in a gene that encodes the protein WASP. The most often used therapy is a bone marrow or stem cell transplant from a matching donor, often a sibling or relative. It can be curative for some patients, mostly those who have a strongly matching donor.

Leading experts in gene therapy, scientists from the field of anti-doping, and sport ethicists joined WADA’s Gene Doping Panel at the Agency’s Fourth Gene and Cell Doping Symposium, held June 5-6 in Beijing to review recent achievements in the field and share the most promising approaches in doping detection under development. Organized with the support of the China Anti-Doping Agency (CHINADA) and Beijing Olympic City Development Association (BODA), the Symposium attracted more than 70 international participants. Sixteen invited speakers included international experts who either study the latest advances in the field of gene therapy and gene doping detection methods, or are involved in related WADA-funded research projects. The 2013 Symposium was the first to dedicate a formal session to cell therapy and doping.
