Welcome to Gene Therapy Net
Gene Therapy Net is the web resource for patients and professionals interested in gene therapy. The objectives of Gene Therapy Net are to be the information resource for basic and clinical research in gene therapy, cell therapy, and genetic vaccines, and to serve as a network in the exchange of information and news related to above areas. In addition, Gene Therapy Net provides an overview for sponsors and researchers of the different international regulations and guidelines associated with clinical gene therapy trials.

Gene therapy trials for sickle cell disease halted after two patients develop cancer
Posted on: 22 February 2021, source: Science
A company has stopped its clinical studies of a promising gene therapy for the blood disorder sickle cell disease after two people who participated developed leukemia-like cancer. Bluebird bio is now investigating whether a virus it uses to deliver a therapeutic gene caused the cancers, reviving old concerns about the risks of this approach. It’s also possible the cancers stemmed from chemotherapy the patients received to prepare their bodies for the gene’s delivery. “This is really a sad development whatever the cause,” says Donald Kohn of the University of California, Los Angeles, who has led gene therapy trials for sickle cell and other diseases.

Manufacturing Considerations for Licensed and Investigational Cellular and Gene Therapy Products During COVID-19 Public Health Emergency
Posted on: 24 January 2021, source: FDA
FDA is issuing this guidance to provide manufacturers of licensed and investigational cellular therapy and gene therapy (CGT) products with risk-based recommendations to minimize potential transmission of the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This guidance is intended to supplement the recommendations to drug and biological product manufacturers provided in FDA’s “Good Manufacturing Practice Considerations for Responding to COVID-19 Infection in Employees in Drug and Biological Products Manufacturing; Guidance for Industry” issued in June 2020 (Ref. 1) (June 2020 GMP Guidance). The recommendations in this guidance specifically consider the source material (cells and/or tissues) recovered from donors and how the CGT product will be manufactured (e.g., cell expansion in culture, viral reduction steps, formulation).

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 One Eye Improves Vision in Both Eyes

It’s not clear why the patients with Leber hereditary optic neuropathy, a mitochondrial disorder that causes blindness, also experienced the modest benefits in their untreated eye. In a Phase 3 gene therapy trial intended to improve vision among patients with Leber hereditary optic neuropathy, recipients gained somewhat better sight in both eyes even though only one was treated. The results and an investigation into possible explanations for the findings were published December 9 in Science Translational Medicine.

Progress in the field of gene and cell therapy continues with rapid development despite the negative impact of COVID-19 on research into novel treatments, according to the director of FDA’s Center for Biologics Evaluation and Research. Peter Marks, MD, PhD, delivered this assessment during the virtual Cell & Gene Meeting on the Mesa.

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.
