Chinese Researchers Claim to Have Genetically Engineered the First HIV-Immune Babies

Posted on: 28 November 2018, source: fortune.com
Researchers in China (Clinical project 'Safety and validity evaluation of HIV immune gene CCR5 gene editing in human embryos') used genetic engineering tools (CRISPR) to create twins theoretically immune to HIV, smallpox, and cholera, MIT Technology Review reported. The medical breakthrough is controversial, as many worry about eugenics and designer babies for the wealthy. The twins, named Lulu and Nana, according to lead scientist He Jiankui of Shenzhen in a YouTube video, were the result of in vitro fertilization (IVF). A few weeks old, they appear to be healthy. When they were a single cell, genetic surgery using a popular tool, CRISPR, “removed the doorway through which HIV enters to infect people.”

Watch the presentation of He Jiankui and discussion during Second International Summit on Human Genome Editing in Hongkong, Wednesday November 28th, 2018.

Gene therapy drugs step toward approval in Japan

Posted on: 14 November 2018, source: Nikkei Asia
Novartis has applied with Japanese authorities to have a gene therapy drug approved, a move that could give Japan at least two such drugs in the coming year, Nikkei has learned. The Switzerland-based pharmaceutical hopes to receive the all-clear in Japan for a neurological disorder treatment sometime next year. It has also applied for approval for the same drug in the U.S. and Europe. In the U.S., the drug is said to be prohibitively expensive -- as much as $4 million to $5 million per patient. The drug treats spinal muscular atrophy, and Novartis expects to be able to market the treatment as early as next year.

Screening Clinical Cell Products for Replication Competent Retrovirus: The National Gene Vector Biorepository Experience

Posted on: 17 September 2018, source: Mol Ther Methods Clin Dev
Replication-competent retrovirus (RCR) is a safety concern for individuals treated with retroviral gene therapy. RCR detection assays are used to detect RCR in manufactured vector, transduced cell products infused into research subjects, and in the research subjects after treatment. In this study, we reviewed 286 control (n = 4) and transduced cell products (n = 282) screened for RCR in the National Gene Vector Biorepository. The transduced cell samples were submitted from 14 clinical trials. All vector products were previously shown to be negative for RCR prior to use in cell transduction. After transduction, all 282 transduced cell products were negative for RCR. In addition, 241 of the clinical trial participants were also screened for RCR by analyzing peripheral blood at least 1 month after infusion, all of which were also negative for evidence of RCR infection. The majority of vector products used in the clinical trials were generated in the PG13 packaging cell line. The findings suggest that screening of the retroviral vector product generated in PG13 cell line may be sufficient and that further screening of transduced cells does not provide added value.

13-Year-Old Boy Is First Person in US to Receive Newly Approved Gene Therapy for Blindness

Posted on: 22 March 2018, source: Gizmodo
On Tuesday, a 13-year-old boy from New Jersey was at the center of medical history as he became the first person in the US to receive an FDA-approved gene therapy for an inherited disease. The event marks the beginning of a new era of medicine, one in which devastating genetic conditions that we are born with can be simply edited out of our DNA with the help of modern biomedical technologies. The therapy, Luxturna, from Spark Therepeutics, was approved by the FDA in December to treat a rare, inherited form of blindness. Its price tag, set at $850,000—or $425,000 per eye—made it the most expensive drug in the US and sparked mass sticker-shock. But the therapy, which in high-profile clinical trials has allowed patients to see the stars for the first times, also offered the almost miraculous possibility of giving sight to the blind.

High-dose AAV gene therapy appears toxic in monkeys and piglets

Posted on: 6 February 2018, source: Science
A gene therapy trial that recently led to dramatic benefits for babies born with a fatal neuromuscular condition has raised hopes for using a similar approach to treat other diseases. But a new animal study suggests that the high doses (2x10E14 genome copies per kilogram body weight) of gene-carrying viruses used in such treatments may not always be as safe as the human clinical trial indicated. In the new research, the disclosure of which briefly sent the stock prices of several gene therapy companies plummeting yesterday, researchers injected a handful of young monkeys and pigs with many copies of adeno-associated virus 9 (AAV9), a normally harmless virus that infects neurons and is increasingly being used to ferry therapeutic genes into cells to treat neuromuscular diseases. Within days, some of the animals developed severe liver and neuron damage.

China is taking the lead in the global race to perfect gene therapies. Scientists have genetically engineered the cells of at least 86 cancer and HIV patients in the country using Crispr-Cas9 technology since 2015, the Wall Street Journal reports (paywall). Although no formal scientific papers have been written about these experiments, doctors told journalists at the WSJ that some patients have improved. There have also been at least 15 deaths, although only about half of them were reportedly related to the gene therapy itself. These therapies, which involved taking the immune cells from hospital patients, editing the cells, and transfusing them back into the body, are the first to use Crispr-Cas9 in living humans.

FDA warns against ‘do it yourself’ gene therapy kits

Posted on: 28 November 2017, source: Bizjournals
The U.S. Food and Drug Administration has issued a stern warning against the use of “do it yourself” gene therapy kits, pushing back against a nascent “biohacker” movement that seeks to make experimental medicines and technologies available to the masses, often by circumventing regulators. A statement posted on the FDA’s website on Tuesday cautions that it is illegal to sell gene therapy products and kits intended for self-administration. Gene therapy involves inserting new, healthy genes into cells to cure diseases that are caused by faulty genes. The FDA has classified gene editing — cutting out and replacing parts of faulty genes — as a form of gene therapy. A host of local biotechs, including Cambridge-based Editas Medicine (Nasdaq: EDIT), are seeking to develop such treatments.

Alarmed by Recent Events, Scientists Speak Out Against DIY Gene Therapy

Posted on: 13 December 2017, source: Gizmodo
It seems hard to fathom that scientific progress has advanced to a point where it’s suddenly possible for people to undertake something as complicated as gene therapy outside the safety and confines of a well-funded lab, but it has. In just the past few months we’ve seen not one, but two examples of people pursuing unregulated gene therapy. That’s right, people are genetically modifying their bodies in DIY labs and friend’s apartments. Now, the largest organization of scientists who work in gene and cell therapy have come out against DIY gene therapies. A statement from the American Society of Gene and Cell Therapy comes on the heels of a stern warning against DIY gene therapy from the US Food and Drug Administration. For years, when it came to biohacking, regulators and establishment science have mainly looked the other way. That seems to be changing.

First gene-editing attempted in human body to cure disease

Posted on: 21 November 2017, source: The Telegraph
Doctors have edited a patient's genes in a world-first attempt to alter DNA from within the human body. Medics in California administered the experimental intravenous treatment, which provides the body with instructions to change DNA, on Brian Madeux, who suffers from Hunter's syndrome. People with Hunter's syndrome are unable to break down long sugary molecules called mucopolysaccharides. This leads to the molecules building up and causing brain and organ damage, and in severe cases it can be fatal. Sufferers require regular enzyme replacement therapy to break down the molecules, but Mr Madeux said he opted to take part in a trial as he is "in pain every second of the day". The 44-year-old from Arizona underwent the treatment at UCSF Benioff Children's Hospital in Oakland, California on Monday.

Gene Therapy in Recurrent Glioma Shows Promise in Early Trial

Posted on: 7 November 2017, source: CancerNetwork
More than 25% of patients with recurrent, high-grade glioma treated with a gene therapy combination were alive more than 3 years after treatment, according to data from a subset of patients in a phase I clinical trial presented at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, held October 26–30 in Philadelphia. The combination treatment involved the retroviral vector Toca 511 and the prodrug of the chemotherapy 5-fluorouracil (Toca FC). Toca 511 is a replicating virus that only infects actively dividing tumor cells. Once inside the cancer cell, the virus delivers a gene for an enzyme, cytosine deaminase (CD). As the virus replicates and spreads to other cancer cells, it programs them to make CD. Next, patients receive a pill, Toca FC, which is an inert compound. Once inside the cancer cell, CD converts Toca FC into the anticancer drug 5-fluorouracil, which kills the cancer cell. 5-fluorouracil also kills certain immune suppressive myeloid cells, boosting the patient’s immune system to recognize and attack the cancer cells.
