Gene therapy is a medical technology that aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells.
Human genetic enhancement or human genetic engineering refers to human enhancement by means of a genetic modification. This could be done in order to cure diseases, prevent the possibility of getting a particular disease, to improve athlete performance in sporting events, or to change physical appearance, metabolism, and even improve physical capabilities and mental faculties such as memory and intelligence. These genetic enhancements may or may not be done in such a way that the change is heritable.
A designer baby is a baby whose genetic makeup has been selected or altered, often to exclude a particular gene or to remove genes associated with disease. This process usually involves analysing a wide range of human embryos to identify genes associated with particular diseases and characteristics, and selecting embryos that have the desired genetic makeup; a process known as preimplantation genetic diagnosis. Screening for single genes is commonly practiced, and polygenic screening is offered by a few companies. Other methods by which a baby's genetic information can be altered involve directly editing the genome before birth, which is not routinely performed and only one instance of this is known to have occurred as of 2019, where Chinese twins Lulu and Nana were edited as embryos, causing widespread criticism.
Leber congenital amaurosis (LCA) is a rare inherited eye disease that appears at birth or in the first few months of life.
Betibeglogene autotemcel, sold under the brand name Zynteglo, is a gene therapy for the treatment for beta thalassemia. It was developed by Bluebird Bio and was given breakthrough therapy designation by the US Food and Drug Administration in February 2015.
Juno Therapeutics Inc. was an American biopharmaceutical company founded in 2013 through a collaboration of the Fred Hutchinson Cancer Research Center, Memorial Sloan-Kettering Cancer Center and pediatrics partner Seattle Children's Research Institute. The company was launched with an initial investment of $120 million, with a remit to develop a pipeline of cancer immunotherapy drugs. The company raised $300 million through private funding and a further $265 million through their IPO.
Voretigene neparvovec, sold under the brand name Luxturna, is a gene therapy medication for the treatment of Leber congenital amaurosis.
Intellia Therapeutics, Inc. is an American clinical-stage biotechnology company focused on developing novel, potentially curative therapeutics leveraging CRISPR-based technologies. The company's in vivo programs use intravenously administered CRISPR as the therapy, in which the company's proprietary delivery technology enables highly precise editing of disease-causing genes directly within specific target tissues. Intellia's ex vivo programs use CRISPR to create the therapy by using engineered human cells to treat cancer and autoimmune diseases.
Sangamo Therapeutics, Inc. is an American biotechnology company based in Brisbane, California. It applies cell and gene therapy to combat haemophilia and other genetic diseases.
The He Jiankui affair is a scientific and bioethical controversy concerning the use of genome editing following its first use on humans by Chinese scientist He Jiankui, who edited the genomes of human embryos in 2018. He became widely known on 26 November 2018 after he announced that he had created the first human genetically edited babies. He was listed in Time magazine's 100 most influential people of 2019. The affair led to ethical and legal controversies, resulting in the indictment of He and two of his collaborators, Zhang Renli and Qin Jinzhou. He eventually received widespread international condemnation.
CRISPR gene editing (CRISPR, pronounced "crisper", refers to "clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral defense system. By delivering the Cas9 nuclease complexed with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added in vivo.
Locus Biosciences is a clinical-stage pharmaceutical company, founded in 2015 and based in Research Triangle Park, North Carolina. Locus develops phage therapies based on CRISPR–Cas3 gene editing technology, as opposed to the more commonly used CRISPR-Cas9, delivered by engineered bacteriophages. The intended therapeutic targets are antibiotic-resistant bacterial infections.
bluebird bio, Inc., based in Somerville, Massachusetts, is a biotechnology company that develops gene therapies for severe genetic disorders.
CRISPR Therapeutics AG is a Swiss–American biotechnology company headquartered in Zug, Switzerland. It was one of the first companies formed to utilize the CRISPR gene editing platform to develop medicines for the treatment of various rare and common diseases. The company has approximately 500 employees and has offices in Zug, Switzerland, Boston, Massachusetts, San Francisco, California and London, United Kingdom. Its manufacturing facility in Framingham, Massachusetts won the Facilities of the Year Award (FOYA) award in 2022. The company’s lead program, exagamglogene autotemcel, or exa-cel, was granted regulatory approval by the US Food and Drug Administration (FDA) in December 2023.
Regenerative Medicine Advanced Therapy (RMAT) is a designation given by the Food and Drug Administration to drug candidates intended to treat serious or life-threatening conditions under the 21st Century Cures Act. A RMAT designation allows for accelerated approval based surrogate or intermediate endpoints.
Excision BioTherapeutics is a biopharmaceutical company based in San Francisco focused on developing gene therapies against HIV infection.
Exagamglogene autotemcel, sold under the brand name Casgevy, is a gene therapy used for the treatment of sickle cell disease and transfusion-dependent beta thalassemia. It was developed by Vertex Pharmaceuticals and CRISPR Therapeutics.
Victoria Gray was the first patient ever to be treated with the gene-editing tool CRISPR for sickle-cell disease.
The Innovative Genomics Institute (IGI) is an American nonprofit scientific research institute founded by Nobel laureate and CRISPR gene editing pioneer Jennifer Doudna and biophysicist Jonathan Weissman. The institute is based at the University of California, Berkeley, and also has member researchers at the University of California, San Francisco, UC Davis, UCLA, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, Gladstone Institutes, and other collaborating research institutions. The IGI focuses on developing real-world applications of genome editing to address problems in human health, agriculture and climate change.
