About GTC Biotherapeutics

GTC Biotherapeutics develops, produces, and commercializes therapeutic proteins through transgenic animal technology. In August 2006,ATryn®, GTC’s recombinant form of human antithrombin, was approved by the European Commission for use in patients with hereditary antithrombin deficiency undergoing surgical procedures. This was the first approval anywhere in the world of a therapeutic protein produced from a transgenic animal.Antithrombin is a protein with anticoagulant and anti-inflammatory properties. We have developed goats that have the human antithrombin gene linked to a milk-protein promoting gene so that they express this protein in their milk. This transgenic approach provides the opportunity to produce recombinant forms of proteins, such as antithrombin, that are difficult to express in economically viable quantities in conventional production systems. In addition, GTC has established a strategic collaboration with LFB Biotechnologies of France to jointly develop recombinant forms of human plasma proteins and monoclonal antibodies. The first program of the collaboration will be to develop recombinant human factor VIIa as a potential treatment for hemophilia in patients with antibodies to other coagulation factors.



In 2006, GTC was granted 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 those that are required in large volumes.

17/05/2007 - The critical role transgenic animals could play in the future of biopharmaceutical production has been tackled by a task force in a new report out this week.

The potential such animals could have in the manufacture of biopharmaceutical proteins has been one of the major incentives driving investigation and creation of transgenic animals, and with therapeutic products derived from these genetically modified creatures now beginning to gain regulatory approval, commercial interest is in the technique is hotting up.

The significant cost savings to be had through using transgenic livestock instead of traditional methods of protein production have been well documented, and comparisons make for stark reading.

To illustrate, experts have estimated that producing a single gram of therapeutic protein using traditional cell lines such as Chinese Hamster Ovary (CHO) cells can cost anywhere from $300 to $3,000 (€221 to €2210).

In contrast, using a transgenic goat to produce the protein in milk drops the cost to $20-$105 per gram, and transgenic hen eggs are even cheaper, working out at around $0.1-$0.25 per gram of protein

The initial capital expenditure is also somewhat less intensive using transgenic livestock, with the cost of constructing a new facility based on traditional cell-based techniques hitting $150m - $400m, compared with the cost of a transgenic goat or cow at $10,000 - $50,000, or a transgenic chicken coming in at $1,000.

"With moderate alterations in production practices, it is possible to take advantage of the tremendous protein-producing capabilities of domestic livestock," states the report, published this week by the Council for Agricultural Science and Technology (CAST).

"Biopharming, the production of biopharmaceuticals using domestic livestock, can have significant advantages compared with other production methods in terms of safety, biological activity, and production costs."

Back in June 2006 the European Medicines Agency (EMEA) gave the very first European approval of a transgenically produced protein product. ATryn, produced by US firm GTC Biotherapeutics, is produced in the milk of goats that have a transgene for human antithrombin, and is used as an anticoagulant to treat a rare congenital disease.

This first step to move trangenically produced protein products out onto the market could prove to be the just the tip of the ice-berg, with all eyes on ATryn to see how it fares out in the cold reality of the marketplace.

According to the chairperson of the CAST task force, Carol Keefer, wide-scale commercial adoption of protein production using transgenic animals is getting closer and closer, with GTC's product cutting a path for other biotech companies.

"I think as soon as ATryn goes to market and proves acceptable and profitable, more pharma companies will explore the use of transgenic animals for protein production," she told in-PharmaTechnologist.com.

Already there are many companies investing in research into producing bioproducts through transgenic livestock. The majority are still in research stages, but US company Avigenics and Netherlands-based firm Pharming currently both have products in clinical trials.

Aside from the economic cost benefits biopharming appears to promise, the procedure can also offer other distinct advantages over current cell-based production methods.

For example, using transgenic animals to produce biopharmaceuticals currently harvested from human tissues represents a safer technique in terms of preventing transmission of human diseases such as HIV/AIDS or Creuzfeldt-Jakob disease, say the report authors.

In some cases, using transgenic animals can also lead to production of a better protein, said Keefer, i.e. a protein more similar to the version naturally produced in humans.

"Proteins are modified during production in the cell, and transgenic animals can do these modifications in a manner more similar to the human-produced protein than other production systems such as yeast or bacteria."

Despite the apparent attractions of biopharming, the report acknowledges that it is critical to establish economic feasibility of the process before it will be adopted by drug firms. For example, issues surrounding protein purification can seriously affect the ultimate economics and commercialisation of a final product.

Feasibility concerns or lack of funding have caused some commercial pharma projects applying these new technologies to be scrapped or delayed on a purely economic basis.

"These are business issues caused not necessarily by technical challenges but by unknown factors that arise as new technologies develop without an established track record or sufficient guidelines for completing the necessary regulatory steps," states the report.

"In fact, regulatory guidelines are being developed concurrently with the establishment of the new technology, creating uncertainty within the business community as to the costs and timelines associated with recombinant protein production."

While transgenic livestock are likely to play an increasingly significant role in the production of therapeutic proteins, Keefer was by no means suggesting that it would to do away with other production methods altogether.

"Each production method has its advantages and disadvantages," she said.

"Depending on the protein, the amount of protein needed (based on market demand and dosage required), and the activity of the protein, a company would choose the best suited system. [For example] if the therapeutic protein could have an effect on the physiology of the transgenic animal, then you would either modify the protein so it was inactive during production, or perhaps choose another system."

Despite this, the authors of the report clearly have very high expectations of biopharming and the part it will play in the production of new medications to treat human diseases. The unique possibilities that transgenic livestock present in this area are too big a prospect to be ignored, and the authors call for "continued support of research by both government and commercial entities...such that additional promising biotherapies can be developed."

SAT0020 MM-093 IS SAFE AND WELL TOLERATED IN AN EXPLORATORY PHASE 2 STUDY AND PATIENTS WITH THE HIGHEST SERUM LEVELS OF MM-093 ACHIEVED ROBUST CLINICAL RESPONSES
J. Murray1, A. Sawitzke2
1Clinical, Merrimack Pharmaceuticals, Inc, Cambridge, 2Rheumatology, University of Utah, Salt Lake City, United States

Background: MM-093 is a non-glycosylated, recombinant version of human alpha-fetoprotein that is produced by recombinant DNA technology in a transgenic goat expression system. The purpose of this exploratory dose-ranging study was to evaluate the safety and efficacy of MM-093 in patients with moderate-severe RA despite current MTX therapy.

Methods: Adults with active RA [≥6 swollen joints; ≥6 tender joints]; ≥6 months’ duration of RA; and on stable MTX therapy were randomized to receive MM-093 (2.5mg, 7.5mg, 20mg) or placebo. Study drug was administered by the patient as a subcutaneous injection in their abdomen once a week for 6 months. A total of 259 patients were randomized at 39 centers in the United States. The primary endpoints were safety and efficacy as measured by ACR20 response. Secondary efficacy endpoints included DAS28-CRP and EULAR.
Results: MM-093 was safe and well tolerated across all dosing groups. The number of patients experiencing an adverse event (AE); the relationship of AE’s to study drug; and the severity of AE’s was similar between groups. There were no dose relationships in any of the lab analytes or in any of the clinically significant lab abnormalities. Additionally, there were no drug related SAE’s in the active groups and none of the patients had detectable limits of anti-MM-093 antibodies.

In the intent to treat population, there was a non-statistically significant improvement in ACR20 in the 20mg group versus placebo. The percentage of patients achieving a EULAR “good” + “moderate” response was statistically significant in the 20mg group versus placebo (p = 0.038) and there was a -1.6 improvement in the DAS28-CRP score from baseline in the 20mg group, compared to a -1.3 improvement in the placebo group.

In general, clinical responses increased as serum levels of MM-093 increased. In patients with the highest serum levels of MM-093 (i.e. >1600ng/ml), 7/9 achieved an ACR20, 8/9 achieved a moderate/good EULAR response and 6/9 had low disease activity or were in remission as measured by DAS28-CRP (See Table below).

Conclusion: In an exploratory dose-ranging study, MM-093 was safe and well tolerated. Patients with serum levels above 1600ng/ml showed a robust clinical response, suggesting that higher doses need to be tested in future trials with MM-093.

GTCB1.21, +0.01, +0.8%) and LEO Pharma A/S announced today that ATryn(R), the first recombinant human antithrombin therapeutic and the first transgenically produced drug, is being introduced to the international medical community at the International Society on Thrombosis and Haemostasis, or ISTH, Bi-Annual Meeting. ATryn(R) is being commercialized and further developed in Europe by LEO, GTC's development and commercialization partner in Europe, Canada and the Middle East.
The Congress is taking place in Geneva, Switzerland from July 6 through July 12. ATryn(R) related events at ISTH include:
-- Two posters by R. Campbell Tait, MD, Glasgow Royal Infirmary, et al, presented by Johan Frieling, MD, Ph.D, GTC Consulting Medical Director, describing dosing strategies for managing antithrombin levels in patients with hereditary antithrombin deficiency undergoing surgery or delivery, procedures that are associated with a high risk for developing a thromboembolism.
-- A scientific symposium moderated by Mario von Depka, MD, Ph.D Director, Werlhof Institute for Thrombosis and Haemostasis, Hannover, Germany entitled, "ATryn(R), The First Recombinant Antithrombin: Innovation or Alternative?" The symposium includes presentations and a panel discussion with Dr. von Depka (clinical data), Dr. Harry Meade, Sr. Vice President, Research, GTC, (transgenic technology), and Dr. Carol Ziomek, Vice President, Development, GTC, (product purity).
-- A press conference and panel discussion on Monday, July 9 (Room F) hosted by Geoffrey Cox, Ph.D, Chairman, President and CEO, GTC Biotherapeutics, titled, "Recombinant Antithrombin: Clinical Opportunities from Transgenic Production." Panel members include Dr. von Depka, Dr. Meade, and Dr. Ziomek.
-- An exhibition booth hosted by LEO. LEO anticipates sales of ATryn(R) as reimbursement prices are established on a country-by-country basis through the remainder of 2007 and into 2008.
Antithrombin, produced in the liver and circulated in blood plasma, has both anticoagulant and anti-inflammatory properties. The recombinant form is produced using GTC's transgenic production platform, enabling large volume supply of antithrombin.
ATryn(R) has been approved for use in Europe for the prophylactic treatment of venous thromboembolism in hereditary antithrombin deficient patients undergoing surgical procedures. GTC is in comparative Phase III studies for a similar indication, including pregnant patients, in the United States. These studies include an evaluation of the incidence of thromboembolism in 17 hereditary antithrombin deficient patients undergoing surgery and pregnancy, and will be compared with the historical records of at least 35 patients who have undergone similar procedures but who were treated with plasma-derived antithrombin products. GTC plans to release data from this research in the fourth quarter of 2007.
Separately, LEO is initiating a Phase II dose-ranging study of ATryn(R) in disseminated intravascular coagulation, or DIC, associated with severe sepsis. The first patient to be treated in this study is expected to be dosed soon. DIC associated with severe sepsis represents a significant unmet medical need in both the United States and Europe, affecting approximately 500,000 patients per year with mortality rates reaching 50%. GTC will have access to the Phase II data for use in the United States and the rest of the world.

Nerve gas antidote made by goats

news.bbc.co.uk/1/hi/sci/tech/6912807.stm

The goats produce the enzyme in their milk
Scientists have genetically modified goats to make a drug in their milk that protects against deadly nerve agents such as sarin and VX.
These poisons are known collectively as organophosphates - a group of chemicals that also includes some pesticides used in farming.

So far, the GM goats have made almost 15kg of a drug which binds to and neutralises organophosphate molecules.

Details appear in Proceedings of the National Academy of Sciences journal.

The drug, called recombinant butyrylcholinesterase, could be used as a protective "prophylactic" drug and also to treat people after exposure to nerve gas.

None of them have been able to produce anything beyond milligram amounts. In the goat, we can make two or three grams per litre

Solomon Langermann, PharmAthene

The US Department of Defense is funding the development effort by biotech firm PharmAthene to the tune of $213m (£105m).

It regards the drug as a promising way to protect its troops against exposure to nerve agents on the battlefield.

Butyrylcholinesterase could also be stockpiled for use in the event of a terrorist attack on a city with chemical weapons.

It is an enzyme that is made in small quantities by the human body.

The compound can be purified from blood, but the yields are poor.

However, the team at PharmAthene has been able to produce butyrylcholinesterase in large, commercial quantities and, the company says, at a reasonable cost.

Tough task

"It is a very difficult molecule to produce. There is a long history of people trying to produce this in everything from insects to yeast to bacteria and mammalian cells," said Dr Solomon Langermann of PharmAthene, a co-author on the PNAS paper.

"None of them has been able to produce anything beyond milligram amounts. In the goat, we can make two or three grams per litre."

The researchers inserted DNA for making the human form of butyrylcholinesterase into a "vector" molecule. This vector is then introduced into a goat embryo.

This allows the human gene to be incorporated into the goat's DNA sequence. The resulting female animals, all healthy, produced large quantities of butyrylcholinesterase in their milk.

The high yields are partly down to "control elements" - stretches of DNA added, along with the human gene, to the vector molecule.

These control elements regulate how much of the enzyme the goat produces and ensure that most of it is produced in the milk, rather than in other tissues.

Safety trial

Once the enzyme was purified from milk, the scientists injected it into guinea pigs, and saw that it remained active in the bloodstream.

The commercial name given to the butyrylcholinesterase enzyme is Protexia.

Dr Langermann said that Protexia was more effective than the combination of the drugs atropine and 2-PAM currently carried by soldiers for protection against nerve agents.

"Those (older) drugs get cleared from the blood very rapidly. Even if the soldier were to survive, they would have very severe neurological damage," he told BBC News.

"With Protexia, you would survive and be able to go back on the battlefield."

It is also effective against a variety of different organophosphate poisons.

The product is still several years from entering use; it needs to pass a safety trial and seek approvals from the US government.

UIT DE NEW YORK TIMES

By ANDREW POLLACK
Published: July 30, 2007
Because of the high prices that drugs can command, medicine — not food — might provide the earliest payoff from genetically engineered livestock.

A herd of goats engineered to produce a therapeutic human protein called antithrombin in their milk live on a farm in central Massachusetts. The animals are owned by a company called GTC Biotherapeutics, which extracts the protein for use in treating a human hereditary condition in which people lack antithrombin, which helps keep blood from clotting.

GTC’s drug has already been approved in Europe, and the company is now conducting clinical trials in hopes of filing for United States approval early next year.

Other companies, too, are at work on medicines that would be extracted from a transgenic animal’s milk or blood, saying the approach might be less expensive than other ways of making protein drugs.

Pharming Group, a Dutch company, has applied for European approval of a drug made in the milk of transgenic rabbits. Pharmathene, based in Annapolis, Md., is developing transgenic goats whose milk produces an antidote to nerve gas.

Hematech, a South Dakota company owned by the pharmaceutical division of Krin, the Japanese beer company, has developed cows with human immune systems to produce human antibodies to treat diseases. Other companies and academic scientists are developing chickens that produce drugs in their eggs and pigs with organs that would not be acutely rejected if transplanted into people.

But the path has not been easy, and many companies have had financial or technological setbacks.

Medical therapies produced in genetically engineered animals would generally be regulated like other drugs. But the new federal regulatory guidelines being developed for transgenic animals might also cover at least the creation and testing of the drug-bearing creatures. And those rules would apply if the companies tried to sell their animals for food after their drug-producing days were over.

One ambiguity involves the offspring of genetically engineered animals, some of which do not inherit their parents’ foreign gene and as a result are genetically normal. There is also the question of what to do about non-engineered animals that are used simply as surrogate mothers to carry embryos that have been given foreign genes. The surrogate mothers’ own genetic makeup remains normal.

GTC, at least, says it has no intention of putting any of its animals, even the non-transgenic ones, into the food supply, to avoid additional regulatory headaches and the chances of a mix-up. The company incinerates its genetically altered goats after they die, and it has the non-altered ones buried by a licensed contractor, according to Thomas Newberry, a GTC spokesman.

“We think it’s better to deal with all the animals at the same quality level, at the same access control,” Mr. Newberry said, “and not try to make a nickel here and there trying to sell goat cheese.”

GTC BIOTHERAPEUTICS AND LFB BIOTECHNOLOGIES DEVELOPING CD20 ANTIBODY
FRAMINGHAM, MA and PARIS, FRANCE – August 2, 2007 -- GTC Biotherapeutics, Inc. ("GTC", Nasdaq: GTCB) and LFBBiotechnologies, a wholly owned subsidiary of LFB S.A. (Laboratoire francais du Fractionnement et des Biotechnologies S.A.), announced today that they have initiated development of a transgenically produced CD20 monoclonal antibody under the existing agreement between GTC and LFB Biotechnologies. The resulting product is expected to have target specificity similar to Rituximab (Rituxan®, Mabthera®) and to have relatively higher antibody dependent cell-mediated cytotoxicity, or ADCC. The existing relevant CD20 antibody patents will expire by 2014. The transgenically produced CD20 antibody is anticipated to be commercially developed for oncology and auto-immune indications. Rituximab is used in the treatment of B-cell non-Hodgkin’s lymphoma, B-cell leukemia and rheumatoid arthritis. It is also under investigation for a range of auto-immune conditions such as systemic lupus erythematosus, immune thrombocytopenic purpura (ITP), and type-1 diabetes. Rituximab had worldwide sales of nearly $4 billion in 2006 and is projected to have a $5 billion market by 2010.

“Rituximab, an antibody targeting CD20, has proven its therapeutic value in Non Hodgkin’s Lymphoma and rheumatoid arthritis,” stated Yann Echelard, Ph.D., Vice President of Research and Development for GTC. “We believe our transgenic production technology enables us to develop an anti-CD20 monoclonal antibody which may have clinical benefits due to enhanced ADCC and provide an attractive price to the market to encourage broader use.”

“Transgenic production has the capability to drive economically beneficial large-scale production of the CD20 antibody,” stated Sami Chtourou, Ph.D., Director Biopharmaceutical Development and Transgenesis Program for LFB. “The enhanced ADCC characteristics have the potential to establish a product that may offer efficacy benefits or reduced dosing requirements for patients.”

This CD20 antibody may be considered for clinical development as a follow-on biologic in the US and a biosimilar in the EU as the appropriate legislation is enacted and regulatory guidance is established.

The transgenically produced CD20 antibody is being developed under the agreement between GTC and LFB established in October 2006. Costs and profits from the program are anticipated to be shared 50/50. GTC will have exclusive marketing rights in the US and Canada. LFB will have exclusive marketing rights in the EU. GTC and LFB have co-exclusive marketing rights to the rest of the world. LFB has initially demonstrated production of this CD20 antibody with enhanced ADCC in cell culture.

Production in the milk of transgenic goats is anticipated to be established in 2008 with an investigational new drug application to the US Food and Drug Administration planned for 2010.

Non-Hodgkin Lymphoma, or NHL, is a group of cancers originating in the lymphatic system that is characterized by the malignant transformation of lymphocytes. NHL has an incidence rate of about 20 cases per 100,000 population in the United States, and a worldwide incidence of 5 –15 per 100,000. It is more prevalent in males and occurs at an average age of 50. The incidence of NHL in the US rose 84% from 1975 to 2004, an average yearly increase of 2.8%. NHL is the fifth most common cancer in the United States, where an estimated 63,000 new cases of NHL will be diagnosed in 2007, and where the National Cancer Institute estimates that 18,660 deaths due to NHL will occur (approximately 5% of all US cancer deaths).

CD20 is an antigen located on the surface of mature B-lymphocytes and B-cell derived tumor cells. The CD20 monoclonal antibody recruits the body's natural

FIRST PATIENT ENROLLED INTO ATryn® PHASE II STUDY IN DIC INDICATION


FRAMINGHAM, MA – August 6, 2007 -- GTC Biotherapeutics, Inc. ("GTC", Nasdaq: GTCB) announced today that its partner for ATryn® in Europe, Canada and the Middle East, LEO Pharma A/S, has enrolled the first patient in a Phase II study of the recombinant antithrombin product in the treatment of disseminated intravascular coagulation, or DIC, in association with severe sepsis. Full enrollment of about 200 patients into the Phase II study is planned to take approximately 12 months with results expected to be available in the second half of 2008.



Estimates from the scientific literature are that there are over 1.5 million cases of severe sepsis in the U.S. and Europe and over 500,000 of these patients develop DIC, with a mortality rate of up to 50%. A number of preclinical animal sepsis studies, as well as a human endotoxemia study, suggest that ATryn® may have potential in the treatment of DIC associated with severe sepsis if provided without heparin, a critical care anticoagulant. A number of countries in Europe and Japan include the treatment of DIC associated with severe sepsis in the approved uses of plasma-derived antithrombin products.



In evaluating the clinical and commercial opportunities, GTC has determined that applying the cost of existing treatment options for severe sepsisto the estimated annual incidence of DIC indicates a total potential U.S. market of $2-3 billion per year.



The objective of the Phase II study is to establish safety and to determine the optimum dose to be used in a subsequent Phase III safety and efficacy study. LEO obtained Scientific Advice from the European Medicines Agency, or EMEA, on the design of the Phase II study. GTC plans to use the Phase II results as the basis of a discussion with the Food and Drug Administration on further clinical development of ATryn® for the DIC indication in the U.S. GTC retains full commercial rights in the US, Japan, and the rest of the world outside the LEO territories.



ATryn® is GTC’s recombinant form of human antithrombin. Antithrombin, produced in the liver and circulated in blood plasma, has both anticoagulant and anti-inflammatory properties. The recombinant form is able to be produced using GTC’s transgenic production platform, enabling large volume supply. ATryn® has been approved for use in Europe for the prophylactic treatment of deep vein thrombosis in hereditary antithrombin deficient (HD) patients undergoing surgical procedures.



GTC is also nearing completion of the clinical studies necessary to support the filing of a Biologics License Application for ATryn® in the HD indication planned for the first quarter of 2008. These studies include an evaluation of the incidence of deep vein thrombosis and thromboembolisms in 17 additional hereditary antithrombin deficient patients treated with ATryn® during surgical and pregnancy procedures. A comparative historical study of approximately 35 patients treated with plasma derived antithrombin, and undergoing similar high risk procedures, is also nearing completion. GTC plans on releasing top line data from these studies in the fourth quarter of 2007. GTC is in discussions for potential commercial partnering for ATryn®in the U.S. market.

GTC BIOTHERAPEUTICS REPORTS SECOND QUARTER 2007 FINANCIAL RESULTS



FRAMINGHAM, MA – August 9, 2007 -- GTC Biotherapeutics, Inc. ("GTC", Nasdaq: GTCB)reported today its financial results for the second quarter ended July 1, 2007. The total net loss for the quarter was $10.6 million, or $0.14 per share, compared with $9.1 million, or $0.15 per share, in the second quarter of 2006. The total net loss for the first six months of 2007 was $18.1 million, or $0.23 per share, compared to $17.6 million, or $0.29 per share, for the first six months of 2006.



“Our European partner for ATryn®, LEO Pharma A/S, has made good progress in the quarter in introducing the product to the physician community in Europe for the hereditary deficiency indication while also initiating the Phase II clinical study for the large market indication in disseminated intravascular coagulation, or DIC, associated with severe sepsis,”stated Geoffrey F. Cox, Ph.D., GTC’s Chairman of the Board and Chief Executive Officer. “We are also making strong progress in developing our follow-on biologic strategy. We have added a CD20 monoclonal antibody program to the recombinant factor VIIa program in our partnership with LFB Biotechnologies. Both of these programs may be eligible for development as follow-on biologics once appropriate legislation is enacted and regulatory guidance is established in the US and EU.”



ATryn® Commercial Launch Activities and Clinical Progress

LEO Pharma initiated the launch of ATryn® at the International Society on Thrombosis and Haemostasis Congress held in Geneva in July. This introduction included a symposium, poster presentations, an exhibit booth and press conferences. LEO is in the process of establishing prices in various European countries. The first commercial sales are anticipated to be in the United Kingdom and will occur in additional countries as pricing is established.



LEO has opened clinical sites and initiated patient enrollment for the Phase II dose ranging study in approximately 200 DIC patients. DIC is the widespread formation of clots within blood vessels, which often leads to organ failure, and is often associated with severe sepsis. In this indication, the infection and resulting septic condition consume much of the patient’s own antithrombin. This antithrombin deficiency then results in DIC. In addition to a number of research studies that support the potential therapeutic value of antithrombin for this indication, DIC is an approved indication for plasma-derived antithrombin in Japan. DIC occurs in an estimated 500,000 severe sepsis cases in the US and European Union each year, of which up to 50% are fatal, representing a major unmet medical need of significant interest in critical care. We estimate the market size of the DIC indication in the US is $2 billion to 3 billion with additional similarly sized markets in Europe and Japan.



GTC is nearing completion of the Phase III study to support a Biologic License Application in the hereditary deficiency indication in the US. The patients have been identified for data collection to satisfy the required number of historical cases treated with plasma-derived antithrombin products. Sufficient patients in the ATryn® treatment arm have been identified to complete the study and the schedule supports the planned availability of top line results before the end of the year.



Antithrombin is used in patients with hereditary deficiency to reduce the risk of the formation of a blood clot known as a deep vein thrombosis, or DVT, during high risk procedures. The primary endpoint of the U.S. study is based on the observation of clinical symptoms of a DVT together with the comparison to historical data. The results from the 14 patients treated in the hereditary deficiency study for Europe will be combined with data from the current study to give a minimum of 31 evaluable patients.



The data on childbirth patients gathered in this phase III study for the U.S. is planned to be used in a subsequent filing with the EMEA in 2008 to request expansion of the approved label to include childbirth procedures in the European Union.



Follow-on Biologics

Follow-on biologics, which are referred to as biosimilars in Europe, are a strategic development area where the economic advantages of our transgenic production technology may enable appropriate pricing of these products. In addition, the antibody dependent cell-mediated cytotoxicity, or ADCC, characteristics of our technology may offer clinical benefits for follow-on monoclonal antibody products. While the enabling legislation and associated regulatory guidance are not fully established, we have begun the development of two products under our agreement with LFB Biotechnologies that may be eligible for consideration as follow-on biologics. The recombinant factor VIIa program was initiated in the fourth quarter of 2006 to begin developing a product similar to NovoSeven®. GTC and LFB have recently begun a program to develop a CD20 monoclonal antibody that is expected to have target specificity similar to Rituximab (Rituxan®, Mabthera®) with relatively higher ADCC.



Financial Results

Revenues for the second quarter 2007 were $2.8 million, a significant increase from the $0.4 million in the second quarter 2006. This increase was driven by revenues from our contracts with PharmAthene and Merrimack Pharmaceuticals, as well as by revenue from LEO for clinical supplies of ATryn®. Revenues totaled $8.3 million for the first six months of 2007 compared to $2.6 million in the first six months of 2006, an increase of 216%. The six-month increase is primarily due to our contract with PharmAthene and the clinical supply of ATryn® to LEO.



Costs of revenue and operating expenses totaled $13.5 million in the second quarter 2007, approximately 42% higher than the $9.5 million total in the second quarter 2006. Costs of revenue and operating expenses totaled $26.7 million in the first half of 2007, approximately 32% higher than the $20.2 million for the first half of 2006. During the second quarter of 2007, a number of batches of ATryn® were rendered unusable during the fill process at our US based fill/finish contractor. We recorded a $2.9 million charge to cost of revenue in connection with the write-off of the inventory in question. While we are pursuing recovery of our losses, we cannot estimate whether or to what extent we will be successful in these efforts, therefore we make no assumption of the recovery, if any, in our financial statements or projections. Our inventory of finished product is sufficient to support LEO’s plans for commercial sales and clinical studiesand the completion of our US clinical studies.



In the year to year expense comparisons, the increase for the quarter was due to the $2.9 million inventory write-off as well as to expenses incurred in the development of Factor VIIa under our agreement with LFB which was signed in the fourth quarter of 2006. In addition to the Factor VIIa expenses and the ATryn® inventory write-off, the year to year increase for the six-month period also included the cost of ATryn® product sold to LEO.



The per share results were affected by an increase in the weighted average number of shares outstanding from 61.4 million shares for the second quarter 2006 to 77.9 million shares in the second quarter 2007. The weighted avera
