What are ATryn goats?

ATryn is the brand name of the anticoagulant antithrombin manufactured by the Massachusetts-based U.S. company rEVO Biologics (formerly known as GTC Biotherapeutics). It is made from the milk of goats that have been genetically modified to produce human antithrombin, a plasma protein with anticoagulant properties.

Is ATryn discontinued?

The withdrawal was at the request of the marketing authorisation holder, Laboratoire Francais du Fractionnement et des Biotechnologies, which notified the European Commission of its decision to permanently discontinue the marketing of the product for commercial reasons.

How is ATryn harvested?

Atryn, which is given by infusion, is for people with a rare condition called hereditary antithrombin deficiency. The genetically engineered offspring were bred for the presence of antithrombin in their milk. Patients won’t be drinking that goat milk; Atryn is made from the antithrombin harvested from the goat milk.

What is the function of recombinant human antithrombin produced in goats?

ATryn, a recombinant form of human antithrombin III (ATIII) produced in the milk of transgenic dairy goats, is an anticoagulant that is indicated for the treatment of patients with hereditary antithrombin deficiency to prevent the formation of blood clots during surgical procedures.

How was ATryn goat created?

Transgenic goats for breeding and herd propagation were developed by means of cloning technology based on the process of nuclear transfer—the introduction of a cell nucleus into an egg cell that has been enucleated and thus no longer possesses a nucleus of its own.

Who approved the first human biological drug from a goat?

New Antithrombin Drug, ATryn, Approved by FDA. ATryn, an anticoagulant, is the first ever biologic product produced by a genetically engineered (GE) animal – a goat. It is for patients who have a rare disease known as antithrombin (AT) deficiency.

What is the name of the first drug approved by the FDA that was genetically engineered from an animal?

Feb. 6, 2009 — The FDA today approved ATryn, the first drug made in genetically engineered animals. ATryn, which is given by infusion, is for people with a rare condition called hereditary antithrombin deficiency. About 1 in 5,000 people in the U.S. have that condition, according to the FDA.

How do the scientists make blood thinners from genetically engineered goats?

To make the drug, scientists at GTC put DNA for the human antithrombin protein into single cell embryos of goats. Goat embryos with the gene were then inserted into the wombs of surrogate mothers who gave birth to baby goats carrying the new trait.

How are ATryn goats made?

The transgenic animals designed to produce Atryn are goats whose genomes have been altered for the secretion of human antithrombin protein in their milk. The resulting recombinant gene, called a transgene, was then inserted into cells grown in cell culture in a laboratory.

What are the pros and cons of genetically modified animals?

The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.

How have goats been used in bio Pharming?

Use of genetically modified goats has been approved by the FDA and EMA to produce ATryn, i.e. recombinant antithrombin, an anticoagulant protein drug. These products “produced by turning animals into drug-manufacturing ‘machines’ by genetically modifying them” are sometimes termed biopharmaceuticals.

Are there genetically modified goats that make your blood flow?

Editor’s note: We’re posting this story from our September 2006 issue because of recent FDA action on ATryn. In the milk of 30 genetically modified goats on GTC Biotherapeutics’s farm in Charlton, Mass., is a drug that can literally make your blood flow—the human protein antithrombin, which inhibits clotting.

Are there any genetically engineered goats in the world?

The world wasn’t ready. Top: Researchers have genetically engineered goats that produce an antimicrobial enzyme in their milk. Without regulatory approval, however, they’re just goats. Visual: John Decker for Undark

Are there any products derived from the mammary glands of goats?

Products derived from the mammary glands of transgenic goats and sheep have progressed through advanced clinical trials and have been approved by regulatory bodies [9, 10].

When did ATryn become a registered drug in the US?

Antithrombin III (ATIII) (ATryn® from GTC – Biotherapeutics, the United States) produced in the mammary gland of transgenic goats was approved as a drug by the European Medicines Agency in August 2006 and by the FDA in the United States in February 2009. This protein is the first product from a transgenic farm animal to become a registered drug.
