AAV Durability: The Road to a One-Shot Cure

Posted on: 15 April 2022, source: Hansonwade
Inconsistent long-term clinical data has highlighted the need to better understand the durability of AAV gene therapy. At Hanson Wade Intelligence, our Market Research division, we have classified 121 AAV gene therapy trials into 4 distinct groups based on the target tissue type – liver, muscle, CNS and ocular tissues. This allowed us to summarise available data on clinical durability as well as the key findings we observed across tissues, trials, doses and serotypes. We hope that this report will provide gene therapy developers with valuable insights on the durability of the current generation of AAV gene therapies.

Gene Therapy Turns to the Use of Synthetic Biology Principles

Posted on: 4 March 2022, source: Genengnews
A new university spinout company is hoping to use synthetic biology to transform gene therapy manufacture. SynGenSys, from the University of Sheffield, plans to tap into engineering design principles to create synthetic promoters to target therapeutic genes to the correct patient tissues. “Typically, people use viral promoters, such as cytomegalovirus as their go-to promoter, but it’s a really complex piece of DNA active in many human tissues,” says David C. James, PhD, professor of bioprocess engineering and co-founder of SynGenSys.

New gene-delivering workhorse could make gene therapy safer, more effective for muscle diseases

Posted on: 13 September 2021, source: Broad Institute of MIT and Harvard
Genetic muscle diseases lead to progressive muscle wasting and often early death, with few treatment options and no cure. Some gene therapies that use a harmless virus to deliver a functioning copy of a disease-causing gene to cells have shown promise in clinical trials for a subset of muscular dystrophies, but have faced challenges. High doses of the gene-carrying virus are needed to reach the muscles throughout the body and the viruses used in these trials often end up in the liver more than in the muscle. This has led to high levels of the virus in the liver, severe adverse side effects, and even death in some trial participants. Researchers at the Broad Institute of MIT and Harvard and Harvard University have developed a new family of adeno-associated viruses (AAVs) - the gene-delivering workhorse of gene therapy - that improve targeting of the muscle tissue, which could be safer and more effective for patients with muscle disease.

Gene therapy delivered to the brain shows promise in children with rare neurodegenerative disease

Posted on: 16 July 2021, source: FierceBiotech
Scientists from Ohio State University have developed a novel method for delivering gene therapy to specific regions of the brain. Now, they have evidence from a small clinical trial in children that the treatment could address a rare, inherited neurodegenerative disease. And they believe their technique could eventually be used to treat more common brain diseases, like Alzheimer’s and Parkinson’s. The Ohio State team developed the gene therapy to treat aromatic L-amino acid decarboxylase (AADC) deficiency, which hampers the body’s ability to make dopamine and serotonin and results in developmental delays and a range of motor and behavioral symptoms. The gene therapy uses a viral vector to carry DNA-expressing AADC to the brain.

A year after getting UniQure's gene therapy, hemophilia patients are still doing better

Posted on: 23 June 2021, source: BioPharma Dive
One year after receiving an experimental gene therapy developed by the Dutch drugmaker UniQure, patients with hemophilia B aren't having nearly as many bleeding issues as they used to have. In hemophilia, genetic mutations prevent the body from making proteins needed to clot blood. People with the less common, "B" form of the disorder are missing a protein known as Factor IX. UniQure's medicine is meant to provide a working version of the gene so patients can generate their own clotting protein, and rely less — or ideally, not at all — on so-called replacement factor treatments.

Liver tumor in gene therapy recipient raises concerns about virus widely used in treatment

Posted on: 23 December 2020, source: Science
It’s troubling news that gene therapy researchers have long anticipated: A hemophilia patient injected with a virus carrying a therapeutic gene in a clinical trial has developed a liver tumor. The U.S. Food and Drug Administration (FDA) has halted the associated clinical trials, and uniQure, the Dutch firm behind the studies, is now investigating whether the virus itself caused the cancer. Gene therapy experts say that’s unlikely. The patient had underlying conditions that predisposed him to liver cancer. Still, scientists say it’s crucial to rule out any role for adeno-associated virus (AAV), the viral delivery system, or vector, that is used in hundreds of other gene therapy trials. “Everyone will want to know what happened,” says physician-scientist David Lillicrap of Queen’s University, a hemophilia researcher who was not involved with the uniQure study.

Gene Therapy in Mesothelioma Patients

Posted on: 28 September 2020, source: mesothelioma.com
Around 1 in 16 people will be diagnosed with lung cancer in their lifetime; this accounts for about 13% of all new cancer diagnoses. However, even with a relatively lower diagnosis rate, lung cancer currently has the highest number of cancer deaths at nearly 22%. Among all the various subtypes of cancer categorized under the umbrella term, “lung cancer,” mesothelioma is one of the most lethal forms.
Despite accounting for around .2% of all cancer diagnoses in the United States, mesothelioma’s lethality is among the highest of all forms of cancer. Pleural mesothelioma, the most common form of this cancer, has a 10-year survival rate of only about 5%. Currently, the only known cause of mesothelioma is asbestos exposure, and although no amount of exposure is safe, it is important to note that your risk of developing mesothelioma drastically increases the longer you are exposed. In addition, due to a prolonged latency period, many patients are diagnosed far too late for proper treatment — usually around the age of 65-74.
