GTCB what a deal this seems to be

GTC Biotherapeutics, Inc. is engaged in the development and production of human therapeutic proteins through transgenic technology that enables animals to produce a recombinant form of a specified human protein in their milk. Using this technology, the Company is developing a portfolio of recombinant blood proteins to treat a range of genetic and acquired blood deficiencies, including hemophilia and other blood coagulation disorders. It has also initiated the development of a portfolio of monoclonal antibodies (MAb’s), for use as potential follow-on biologics targeted at several market products. Its first product ATryn, its recombinant form of human antithrombin, validated its transgenic production technology’s capability. In February 2008, it announced that ATryn had met the statistical requirements for the primary endpoint in its trial to support its filing of a Biologics License Application (BLA), for the use of ATryn in United States.

FDA Advisory Committee Recommends GTC Biotherapeutics' ATryn* (antithrombin [Recombinant]) If approved, ATryn will be first recombinant human antithrombin available in the U.S.

This deal has been all over the charts, from $0.28 to $0.80 on word of the possible approval.

On Friday the 9th of January the stock was halted during the FDA advisory meeting. At 6:30 pm the news was out that ATryn was recommended.

Monday morning premarket the stock traded as high as $1.00, opened at $0.83, closed at $0.66 and continues to fall.

The positive side of this company is the approval date is set for Feb 7th, 2009. Be sure to watch this as there is sell presure bringing it down, another mans trash is another mans treasure.

FDA Issues Guidelines For Genetically Altered Animals WASHINGTON (Dow Jones)--The U.S. Food and Drug Administration on Thursday issued final industry guidelines for the use of genetically-engineered animals that could be used to create drugs for human use.
So far, the FDA hasn't approved any drugs made from altered animals, but has applications pending. Last week, an FDA panel backed a GTC Biotherapeutics Inc. (GTCB) product derived from the milk of genetically altered goats to treat a rare blood-clotting disorder, ruling that it was effective.
The product, Atryn, is made from the milk of goats that were genetically engineered to produce human antithrombin. The same technology could be used to produce other products.
The FDA said the industry guidelines clarify its statutory and regulatory authority and provide recommendations to producers of altered animals to help them meet their obligations and responsibilities under the law.
"Genetic engineering is a cutting-edge technology that holds substantial promise for improving the health and well-being of people as well as animals," said Randall Lutter, FDA's deputy commissioner for policy, said in a statement.
"This guidance will help the FDA efficiently review applications for products from GE [genetically engineered] animals to ensure their safety and efficacy," he continued.
The agency said it would bring products made from genetically altered animals to public-advisory committees for a discussion.

FDA pledges openness on gene-altered products
By RICARDO ALONSO-ZALDIVAR

WASHINGTON (AP) — Federal health officials Thursday pledged a new, open process for approving drugs and foods from genetically engineered animals.

Consumer groups complained the policy won't do enough to tell people if they're eating gene-altered animals and fails to protect the environment. They urged the incoming Obama administration to reconsider it.

Genetic engineering, already widely used for crops, is on the threshold of producing animals that can grow faster or even yield drugs that treat human illnesses. Although the potential benefits — and profits — are huge, many individuals have qualms about manipulating the genetic code of other living creatures.

In issuing its long-awaited final policy, the Food and Drug Administration said it will not allow any products from genetically engineered animals to be sold without first submitting them to scrutiny by independent advisers at a public meeting. The government will allow exceptions for research animals, such as lab rats, and the FDA will post those on its Web site.

Genetically engineered — or GE — animals are not clones, which the FDA has already said are safe to eat. Clones are exact copies of an animal. With GE animals, their DNA has been altered to produce a desirable characteristic.

"We will not approve any application until we are convinced of the safety and effectiveness," said FDA biotechnology expert Larisa Rudenko, who has been working on the complex issue since 1989. "The public should rest assured that we are not going to be rushing any decisions."

But consumer groups said the FDA's policy will not require all genetically engineered foods to be labeled as such. And they said the government has not done enough to examine the potential impact of genetically engineered animals on the environment, particularly if some escape and begin to mate with animals in nature.

"They are completely ignoring consumers' overwhelming desire for labeling," said Michael Hansen, a senior scientist with Consumers Union, publisher of Consumer Reports. FDA officials said genetically engineered foods will be labeled if they are different in some important way from natural foods, for example, no-fat filet mignon.

The FDA also failed to require a cradle-to-grave tracking system for genetically engineered animals, said Gregory Jaffe, who heads the biotechnology project at the Center for Science in the Public Interest. He's particularly concerned about animals that are not supposed to enter the food supply chain.

"The FDA has made some small but important changes to increase the transparency of this process," said Jaffe. "It helps, but the devil is in the details."

While not calling for a repeal of the FDA policy, Jaffe urged the incoming Obama administration to work with Congress on a new law that specifically addresses the genetic engineering issue. The FDA based its policy on older laws that apply to animal drugs.

Drugs and foods from GE animals will become increasingly common in the next five to ten years. For example, an FDA advisory committee last week considered approval of an anti-clotting drug produced from the milk of GE goats. The scientific advisers concluded that the drug — ATryn — appears to be safe and effective. A final FDA decision is pending. And a Massachusetts company hopes to win FDA approval this year for a faster-growing salmon.

The biotechnology industry welcomed the FDA's announcement.

"This system will ensure the products made available through this science will go through a rigorous and transparent review process before being approved for the marketplace," said Barbara Glenn, a senior scientific adviser with the Biotechnology Industry Organization

Drugs from genetically engineered poised to debut in U.S.
by Kristen Minogue
Jan 22, 2009

Medication from genetically engineered animals could appear as early as next month if, as anticipated, the Food and Drug Administration approves ATryn, a blood thinner made from the milk of genetically engineered goats.

An FDA committee gave a green light to the drug, manufactured by Framingham, Mass.-based GTC Biotherapeutics, on Jan. 9. The European Commission already approved the drug in August 2006, and the FDA could formally approve it for sale in the U.S. as soon as Feb. 7.

If the agency approved it, the drug could help treat patients with a rare blood-clotting disorder called hereditary antithrombin deficiency.

ATryn is just one of several drugs from gentically engineered animals that could start appearing on the market soon.

“Transgenic animals are probably going to be the drug stores of the future,” said biologist Bryan Pickett, who works with genetically engineered zebra fish at Loyola University of Chicago.

The FDA guidelines for such drugs, released on Jan. 15, outlined a much more stringent review process for genetically engineered animal products than cloned animal products. Unlike clones, which are supposed to be genetically identical to animals that already exist, genetically engineered animals have DNA from other organisms, often other species, inserted into their genome. Milk and meat from cloned cows, pigs and goats received a blanket approval from the FDA in January 2008.

The FDA evaluates every different "recombinant DNA construct "– foreign DNA inserted into an animal – on a case-by-case basis. Developers who want to market products from transgenic animals have to submit a new animal drug application to the FDA. Approval can take up to 10 months.

So far the only genetically engineered animals for sale in the U.S. are a glow-in-the-dark zebra fish sold in pet stores and laboratory animals like mice. The FDA hasn’t received any applications for genetically engineered meat.

Consumers are wary of the new technology. Of the 28,000-plus comments the FDA received on the draft guidelines last fall, the overwhelming majority opposed genetic engineering.

But that isn’t stopping developers, according to University of Illinois at Urbana-Champaign biologist Matthew Wheeler, who co-authored a report on the animals’ potential benefits last June.

Wheeler's report showed genetically engineered animals are popping up in dozens of sectors, including:

 New Medicines – ATryn may become the first transgenic animal-produced drug to hit U.S. markets, but it’s not the only one that’s been developed. Researchers have created milk from genetically engineered sheep and pigs that can treat a rare type of hemophilia. Another strain of genetically altered pigs secretes milk with a hormone to help anemia patients produce more red blood cells.

 Eco-friendly Animals – Researchers created the Enviropig in 2001, a pig that can excrete 60 percent less phosphorus than normal pigs, reducing pollution. Scientists at the National University of Singapore engineered the GloFish, a fluorescent zebra fish now sold in the U.S., to detect water pollution.

 Human-Animal Transplants – Some have greeted this as the solution to the organ shortage problem. Transgenic pig hearts have lasted in baboons for up to six months. Researchers also hope insulin-producing pig cells could help diabetes patients and transgenic pig livers could act as temporary transplants while patients wait for permanent replacements.

 Animal Health – Genetically engineered dairy cows are already able to begin resisting mastitis, an infection that decreases milk production, by secreting the bacteria-killer lysostaphin into their milk. Other possibilities include creating cows resistant to mad cow disease and brucellosis, a bacterial disease that can be transferred to humans.

Pickett said the risk of releasing potentially dangerous genetic materials is very low. But at the same time he respects the FDA’s regulation.

Meanwhile researchers are trying to calm any fears consumers may have about genetic engineering.

“I think all scientists really are for responsible, compliant and responsible, drug policy,” Pickett said.

Spanning wat aan het opbouwen...

America's First Transgenic Drug - Just A Step Away From Approval

(RTTNews) - The first drug to be produced from genetically engineered animals appears very close to becoming real in the United States.

On February 7, the FDA is slated to decide, whether to approve GTC Biotherapeutics Inc.'s (GTC), anti-clotting medicine ATryn to treat patients with hereditary antithrombin deficiency, a rare clotting disorder, when they undergo surgery or face childbirth. The drug was granted orphan drug status by the FDA in 2007. If approved in the U.S., the drug is expected to generate sales of $40 million - $50 million over the next four to five years.

ATryn, which is made from the milk of genetically engineered goats, has already won the backing of the regulatory agency's Blood Products Advisory Committee. The panel has also voted ATryn as "safe and efficacious to prevent and treat venous thromboembolism in hereditary antithrombin deficient patients facing surgery or childbirth". ATryn was approved in Europe in 2006 and the drug is marketed there by LEO Pharma.

According to statistics, a total of 60,000 people in the U.S. and about 80,000 people in Europe have hereditary antithrombin deficiency, or HD. People with hereditary antithrombin deficiency are at an increased risk for venous blood clots, including pulmonary embolism and deep vein thrombosis.

ATryn given in intravenous formulation is for use only during high-risk procedures such as surgery and childbirth, and it is not a replacement for blood thinners prescribed to counter the anti-thrombin deficiency under normal treatment plan.

Company Overview

GTC Biotherapeutics, as it is now known, was spun-off from Genzyme Corp. (GENZ) in 1993 under the name Genzyme Transgenics Corp. The company changed its name to GTC Biotherapeutics in 2002.

ATryn, the first recombinant antithrombin product, is extracted from the milk of goats, which have a human DNA (gene) inserted into them to make them able to produce the human antithrombin in their milk. Antithrombin is a protein that helps keep blood from clotting.

ATryn contains the active substance antithrombin alfa, a copy of the natural blood protein, and it works by blocking thrombin, one of the substances involved in blood coagulation. GTC has licensed ATryn to Ovation Pharmaceuticals Inc. to develop and market the drug in the U.S.

In addition to ATryn, GTC is developing additional recombinant forms of therapeutic proteins normally found in human blood plasma as well as monoclonal antibodies. According to GTC, these products have potential applications in hematology, oncology, and autoimmune diseases.

Pharming - A Quick Glance

In biological context, Pharming refers to the production of therapeutic human proteins in transgenic farm animals. Commonly used transgenic animals are pigs, cows, sheep, and goats. Transgenic animals refer to those animals whose genetic make-up is altered to include selected genes from other animals or species.

Synthetic human insulin produced in 1982 by Eli Lilly & Co. (LLY) is the first successful pharmaceutical product produced by employing transgenic technology. The synthetic human insulin was produced by genetically modified bacteria in bioreactors.

Goats As Bioreactors - Why?

Patients with blood clotting disorders who are facing childbirth or who have to undergo surgery have to stop taking blood thinners like Heparin or Warfarin several days before, as it will lead to excessive bleeding if the drugs are not discontinued. Such patients are given replacement anti-thrombin. Up till now, human blood plasma is the only source of replacement anti-thrombin.

According to Geoffrey Cox, CEO of GTC, it takes just 18 months to produce a lactating animal and in a single year one goat produces the equivalent of 90,000 blood collections. Goats have a gestation period of about 5 months and reach maturity in 1 year.

Moreover, production of recombinant proteins using transgenic livestock costs less than when it is produced in bacterial or mammalian cell culture bioreactor facilities or through cell lines.

Financial Metrics

Since its inception in 1993, GTC has been operating at a loss. For the third-quarter ended September 28, 2008 the company's net loss narrowed to $6.06 million or $0.06 per share from $8.39 million or $0.11 per share in the year-ago period. Revenue for the quarter rose to $2.93 million from $2.58 million in the comparable quarter a year before.

On December 23, 2008 the company completed a $15 million convertible debt financing from LFB Biotechnologies. The net proceeds at closing, after transaction costs and establishment of a restricted cash account, were approximately $10 million. Under the agreement with LFB, the convertible debt will mature on June 30, 2012, and will bear interest at an annual rate of 8%. LFB also has a warrant to purchase GTC common stock at $0.31 per share at any time after June 1, 2009.

January 21, 2009 - GTC, which received a Nasdaq warning about a possible delisting of its stock, regained compliance with the minimum market capitalization listing requirement. The company also has until at least July 20, 2009, to regain compliance with the minimum $1 bid price requirement for stay listed on the Nasdaq market. Since early February 2008, the stock has been languishing below $1. The company expects to build on its strengths with expected near term news regarding ATryn's regulatory review and its commercial launch in the U.S.

The stock closed Monday's trade at $0.85 on an above average volume of 2.23 million shares.

Closing Thoughts

The much-awaited FDA approval of ATryn for the rare hereditary antithrombin deficiency could facilitate FDA approval of the drug for more prevalent disorders. The drug, if approved could also open the door to several 'pharmed' drugs. The Netherlands based Pharming Group N.V. is another biotech company, which is developing medicines using milk from genetically engineered cows and rabbits.

The FDA usually follows the advice of its expert committees, though not mandatory. However, given the FDA's recent stringent drug approval standards, one has to wait and see what the future holds for the drug.

.... So moving Atryn from bench to bedside depends only on the decision of the FDA, which is expected to be announced on February 7. Stay tuned.

ATryn®(Antithrombin [Recombinant]) Approved by the FDA


Only recombinant option for patients with hereditary antithrombin deficiency, a rare and potentially life-threatening condition

Framingham, MA, andDeerfield, IL, February 6, 2009 – GTC Biotherapeutics ("GTC", NASDAQ: GTCB) and OVATION Pharmaceuticals, Inc. announced today thattheU.S. Food and Drug Administration (FDA)approved ATryn®(Antithrombin [Recombinant])for the prevention ofperi-operative and peri-partum thromboembolic events in hereditary antithrombin deficient patients. It is not indicated for treatment of thromboembolic events in hereditary antithrombin deficient patients.ATryn is the first ever transgenically produced therapeutic protein and the first recombinant antithrombin approved in the U.S. Alongwith the approval of ATryn, the FDA’s Center for Veterinary Medicine also approved GTC’s New Animal Drug Application, the first of its kind to regulate genetically engineered animals. This is now required for a recombinant technology used to develop transgenic animals, such as the goats that produce recombinant antithrombin. GTC has granted OVATION the right to market ATryn in the U.S. and pursue further clinical development.The companies expect ATryn to be available in the second quarter of 2009.



People with hereditary antithrombin deficiency are at increased risk for venous thromboembolic events, including pulmonary embolism and deep vein thrombosis, which can be life-threatening, particularly in high risk situations. Antithrombinis a natural anticoagulantthat plays an important role incontrolling the formation of blood clots. Purified recombinant antithrombin has the same amino acid sequence as antithrombin derived from human plasma.



“The approval of ATrynmarks a significant milestone in the development of this innovative recombinant technology and delivers a new therapeutic option to benefit hereditary antithrombin deficient patients who are undergoing surgery or childbirth procedures,” said Geoffrey F. Cox, Ph.D., GTC’s Chairman and Chief Executive Officer. “Advancing this novel technology from the early days of demonstrating its capability to the daily practice of producing a safe and efficacious product for the U.S. and the European Union, is a testament to the persistence and capability of our employees.”



ATryn was developed to provide asafe and consistent supply of recombinant antithrombin.3



"With FDA approval of ATryn, we can help ensure that patients with hereditary antithrombin deficiency, a rare clotting disorder associated with severe complications, have access to much needed therapy," said Jeffrey S. Aronin, OVATION President and Chief Executive Officer. “Bringing ATryn to marketgives us the opportunity to make a meaningful difference in the lives of peoplewiththis rare disorder and is consistent with Ovation’s mission of addressing unmet medical needs of small patient populations.”

The safety and efficacy of ATryn was established in clinical studies conducted in hereditary antithrombin deficient patients with a history of thromboembolic events in the U.S., Europe and Canada. During these studies, ATryn was shown to prevent the formation of clinically overt thromboembolic events. Post-marketing studies will be performed to assess safety and immunogenicity after repeat dosing.



The prevalence of hereditary antithrombin deficiency in the general population is approximately one in 2,000 to one in5,000.Half these patients may experience a thrombosis before 25 years of age and, based on a study, up to 85 percent may suffer a thromboembolic event by age 50.



About ATryn
ATryn is the first recombinant antithrombin product approved in the world and the first antithrombin product that has been approved through the centralized procedure in the European Union.It is now also the first recombinant antithrombin product approved by the FDA.

Important Safety Information

ATrynis contraindicated in patients with known hypersensitivity to goat and goat milk proteins.Allergic-type hypersensitivity reactions, including anaphylaxis are possible. If these reactions occur during administration, treatment must be discontinued immediately and emergency treatment should be administered.

The anticoagulant effect of drugs that use antithrombin to exert their anticoagulation may be altered when ATryn is added or withdrawn.To avoid excessive or insufficient anticoagulation, coagulation tests suitable for the anticoagulant used (e.g., aPTT and anti-Factor Xa activity) are to be performed regularly, at close intervals, and in particular in the first hours following the start or withdrawal of ATryn. Additionally, patients must be monitored for the occurrence of bleeding or thrombosis in such situations.

The serious adverse reaction that has been reported in clinical studies is hemorrhage (intra-abdominal, hemarthrosis and post procedural). The most common adverse events reported in clinical trials at a frequency of ≥ 5% are hemorrhage and infusion site reaction.

For more information including full prescribing information go to www.ovationpharma.com.

About Transgenic Production

The process for producing ATryn involves scientists inserting DNA for the human antithrombin protein into a single-celled goat embryo. This embryo is implanted into a surrogate doe. The resulting transgenic offspring are able to produce high levels of antithrombin in their milk. This protein is collected and purified from the milk to produce ATryn, which is administered to patients by intravenous infusion.

About GTC Biotherapeutics

GTC Biotherapeutics develops, supplies, and commercializes therapeutic proteins produced through transgenic animal technology. In addition to ATryn, GTC is developing a portfolio of recombinant human plasma proteins with known therapeutic properties. These proteins include recombinant forms of human coagulation factors VIIa, VIII, and IX, which are being developed for the treatment of hemophilia, and alpha-1 antitrypsin.



GTC also has a monoclonal antibody portfolio that includes a monoclonal antibody to CD20 and a monoclonal antibody to CD137. GTC’s intellectual property includes a patent in the United States through 2021 for the production of any therapeutic protein in the milk of any transgenic mammal. GTC’s transgenic production platform is particularly well suited to enabling cost effective development of proteins that are difficult to express in traditional recombinant production systems as well as proteins that are required in large volumes.
