Press Release Source: Maxygen, Inc. On Monday October 10, 2011, 5:00 pm EDT

REDWOOD CITY, Calif.--(BUSINESS WIRE)-- Maxygen, Inc. (Nasdaq:MAXY - News), a biotechnology company, today announced that the United States Patent and Trademark Office (PTO) has issued a Right of Appeal Notice in the inter partes reexamination proceeding for Amgen’s U.S. Pat. No. 7,381,804 (the ‘804 patent) that includes a final rejection of all claims in the ‘804 patent. Amgen’s ‘804 patent includes certain claims to mutated granulocyte colony stimulating factor (G-CSF) molecules that potentially cover Maxygen’s MAXY-G34 product candidate, a next-generation, pegylated G-CSF. Maxygen submitted the request to the PTO for an inter partes reexamination of the Amgen patent in 2009. Amgen has the right to appeal the decision to the PTO’s Board of Patent Appeals and Interferences.

“We are very pleased with the outcome of the reexamination proceeding, and we believe that this result provides a foundation for our efforts to generate further value from the MAXY-G34 program for our stockholders,” said James R. Sulat, Maxygen’s Chief Executive Officer.

Maxygen selling hemophilia unit to Bayer
Wednesday July 2, 10:07 am ET
Maxygen selling hemophilia unit to Bayer's health care unit for $90 million upfront

NEW YORK (AP) -- Bayer's health care unit is buying Maxygen Inc.'s hemophilia unit for $90 million upfront and potential future fees of up to $30 million in a move to expand its specialty pharmaceutical business, the companies said Wednesday.

Hemophilia is an inherited bleeding disorder caused by deficient or defective blood clotting proteins. Roughly 20 percent to 30 percent of patients with hemophilia develop antibodies to current therapies, so a mechanism called Factor VIIa is used to help these individuals form clots.

Germany's Bayer will gain the Redwood City, Calif.-based biotechnology company's lead drug candidate MAXY-VII, along with a license to use the company's underlying gene targeting technology.

MAXY-VII is expected to move to early-stage clinical studies in the third quarter. Bayer already sells Factor VIII product Kogenate for the treatment of hemophilia A, which affects about 1 in 10,000 births.

Shares of Maxygen surged 90 cents, or 25.6 percent, to $4.41 during morning trading. The stock has traded between $3.28 and $9.56 over the last 52 weeks.

[Bill_Investor]

I just purchased a few thousand shares at $3.84. Stop loss at $3.50 or so if things go south. Plenty of insider buying activity over the last week, plus I feel the Amgen patent issue is overblown.

Good luck.

Maxygen plunges on potential Amgen patent dispute
Friday June 13, 10:55 am ET
Maxygen shares plunge as Amgen gets patent which threatens product launch, patent litigation

NEW YORK (AP) -- Shares of Maxygen Inc. plunged 27 percent Friday, after the biotechnology company said it may be open to patent infringement litigation from rival Amgen Inc.

In a filing with the Securities and Exchange Commission, Maxygen said Amgen received a patent which appears to cover the company's drug MAXY-G34, which treats a common chemotherapy-induced blood disorder known as neutropenia. The drug is not yet on the market.

While Maxygen believes the patent will eventually be invalidated in court, it does give Amgen grounds to sue Maxygen, just as MAXY-G34 approaches marketing. If the company isn't able to overturn the patent, the drug's launch could be delayed by two years, estimated Cowen and Co. analyst Eric Schmidt.

While Schmidt notes that the news adds incremental litigation risk to Maxygen, he thinks the company's share price is cheap in relation to its protein engineering platform and drug pipeline.

Goldman Sachs analyst May-Kin Ho expected the news to pressure Maxygen shares, given that investors may now be uncertain about how the Amgen patent will affect potential partnership deals for MAXY-G34, launch timing and potential legal disputes which may take years to resolve.

In morning trading, Maxygen shares fell $1.30, or 27 percent, to $3.55 on 10 times average daily volume.

Maxygen warns of possible Amgen suit

Maxygen warns of possible Amgen patent-infringement suit

WASHINGTON (AP) -- Maxygen Inc. warned Friday that Amgen Inc. may sue the company for patent infringement relating to Maxygen's Maxy-G34 drug candidate.

Maxy-G34 is designed to be the improved version of granulocyte colony-stimulating factor, or G-CSF, for the treatment of neutropenia, according to a Securities and Exchange Commission filing Friday.

Neutropenia is an abnormally low number of neutrophils, a type of white blood cell, in the blood. White blood cells help fight bacterial infections.

Maxygen, a Redwood City, Calif.-based biopharmaceutical company, said the U.S. Food & Drug Administration granted a patent to Amgen on June 3 with certain G-CSF claims.

Maxygen said it has been granted four patents related to Maxy-G34. Maxy-G34 is currently in Phase II clinical trials.

The company said its current activities related to Maxy-G34 are exempt from patent-infringement liability because these activities are limited strictly to obtaining information for regulatory approval.

Maxygen said that if and when its MAXY-G34 related activities extend beyond those related to seeking regulatory approval, such as the commercialization of MAXY-G34, Amgen might start an infringement action against the company based on this patent and/or other related patents that it may be granted in the future.

If Amgen elects to sue the company, Maxygen believes that it will have a viable defense to any such infringement lawsuit and plans to vigorously defend against any such claims, the SEC filing said.

Maxygen said the delay and cost to the company of any patent litigation or other proceedings, such as interference proceedings, even if resolved in its favor, could be substantial.

Shares of Maxygen tumbled $1.23, or 25 percent, to $3.62 in late-morning trading Friday.

However, Amgen shares climbed 76 cents, or 1.8 percent, to $43.98. The biotechnology company is based in Thousand Oaks, Calif.

Maxygen Reports First Quarter 2008 Financial Results
Tuesday May 6, 9:06 am ET

REDWOOD CITY, Calif.--(BUSINESS WIRE)--Maxygen, Inc. (Nasdaq:MAXY - News), a biotechnology company focused on the development of improved protein drugs, today reported financial results and business milestones for the quarter ended March 31, 2008.

“Our major achievement in Q1 was the progress of MAXY-G34, our long-acting G-CSF for treatment of neutropenia,” said Russell Howard, chief executive officer of Maxygen. “During the quarter we completed enrollment of all patients at the 10, 30, and 60 microgram/kilogram dose levels and have seen no safety issues or immunogenicity so far. Good activity at the 30 and 60 microgram/kilogram doses prompted us to explore an additional 45 microgram/kilogram dose, which is also now fully enrolled. We feel confident that we will achieve our goal, on schedule, of identifying a suitable dose to take into Phase IIb studies.”

“Our MAXY-VII and MAXY-4 programs also are progressing well. Our team should be congratulated for successfully transitioning operations from Denmark to the U.S. without interrupting the important work of moving these programs forward.”

In November 2007 Maxygen announced plans to close Maxygen ApS, its subsidiary in Denmark, and consolidate all operations at its U.S. headquarters in Redwood City, CA. Effective February 29, 2008, the company ceased operations at the Denmark site.

First Quarter 2008 Financial Results

Maxygen reported a net loss of $13.7 million, or $0.37 per share, for the first quarter 2008 as compared to a net loss of $7.7 million, or $0.21 per share, for the comparable period in 2007.

Revenue for the first quarter was $1.4 million, compared to $9.1 million for the same period in 2007. The change was due primarily to loss of revenues from a Roche collaboration agreement to develop a novel Factor VIIa for trauma indications. The agreement ended in April 2007.

Total operating expenses for the quarter were $17.2 million compared to $18.9 million in the first quarter of 2007. The decrease in expenses was due to the cessation of operations at Maxygen’s Denmark site on February 29, 2008.

Excluding the impact of non-cash stock compensation expense under SFAS 123(R), Maxygen reported a non-GAAP net loss (see Footnote A) of approximately $12.5 million, or $0.34 per share, in the first quarter of 2008, compared to a non-GAAP net loss of approximately $5.8 million, or $0.16 per share, in the first quarter of 2007.

At March 31, 2008, cash, cash equivalents and marketable securities totaled $133.6 million.

Roche, Maxygen end hepatitis drug development deal
Monday November 26, 1:06 pm ET

Maxygen Inc. and drugmaker Roche will end development of the hepatitis infection drug MAXY-alpha.

Roche in September had placed a hold on the program, which the companies had been developing since 2003.

Roche, which fully funded the MAXY-alpha program, had started a Phase Ia clinical trial in New Zealand at the end of 2006.

Redwood City-based Maxygen (NASDAQ: MAXY) expected no milestone payments in 2007 or 2008, the company said.

"While we are disappointed, we recognized and had advised earlier that termination of the program was one of the likely possibilities," said Maxygen CEO Russell Howard.

MAXY-alpha was designed to treat infections related to hepatitis C, the leading cause of liver cancer cases worldwide, and hepatitis B.

Maxygen to Receive $7 Million From BioFuel Collaboration Between Shell and Codexis
Monday November 19, 9:00 am ET

REDWOOD CITY, Calif., Nov. 19 /PRNewswire-FirstCall/ -- Maxygen, Inc. (Nasdaq: MAXY - News) announced today that it expects to recognize approximately $7 million in revenue in the fourth quarter of 2007 under the terms of Maxygen's license agreement with Codexis Inc.

The payment reflects the expanded collaboration agreement between Royal Dutch Shell plc and Codexis, announced November 6, 2007, for the development of new super enzymes to convert biomass to fuel. The expanded agreement covers five years of research collaboration. In addition Shell made an equity investment in Codexis as part of a larger financing. This financing reduces Maxygen's ownership in Codexis to approximately 25% of Codexis' outstanding shares. Maxygen owns approximately 8.9 million shares of various classes of Codexis preferred stock convertible into common shares and shares of Codexis common stock. The convertible preferred stock of the most recent Codexis financing is senior in liquidation preference to Maxygen's shares and was sold at a price of $8.50 per share.

"We are pleased with the continuing success and increasing value of Codexis' business," said Russell Howard, chief executive officer of Maxygen. "Leveraging Maxygen's MolecularBreeding(TM) technology outside the pharmaceutical industry has provided us with a good source of non-dilutive financing to help drive our protein therapeutic business."

Maxygen established Codexis in 2003 as a spin-out company, and granted to Codexis exclusive licenses to use Maxygen's MolecularBreeding(TM) directed evolution platform for certain chemical applications. In December 2006, Maxygen expanded the scope of exclusive licenses previously granted to include certain applications relating to energy, including biofuels.

Maxygen Announces Hold on MAXY-alpha Development Program

REDWOOD CITY, Calif., Sept. 21 /PRNewswire-FirstCall/ -- Roche has advised Maxygen, Inc. (Nasdaq: MAXY) that it has voluntarily placed a hold on further clinical development of MAXY-alpha, also known as R7025. MAXY-alpha is a novel interferon-alpha for the treatment of Hepatitis C and Hepatitis B virus infections and is licensed to Roche.

Preliminary observations from a Phase I trial indicate that an unexpected reduction of the pharmacodynamic and pharmacokinetic effects of MAXY-alpha occurred in the majority of subjects who received two doses of MAXY-alpha. In addition, antibodies binding to MAXY-alpha were identified in some subjects. Roche has initiated additional investigational studies in order to assess these results.

'We are all surprised by these unexpected findings,' said Russell Howard, Maxygen's chief executive officer. 'We don't yet know how this will impact the future timing or advancement of the program. Roche has now started additional work to assess the meaning and significance of these results. We will provide an update once all relevant information is collected and evaluated.'

About the Maxygen and Roche Agreement

Maxygen and Roche entered into an agreement in 2003 to develop novel interferon alpha and beta products for a wide range of indications. Roche licensed from Maxygen worldwide commercialization rights to specific novel interferon product candidates for the treatment of Hepatitis C and B virus infections. Maxygen received an initial payment, full research and development funding for work done by Maxygen in the first two years of the collaboration, and milestone payments for the advancement of the MAXY-alpha product candidate. In addition, Maxygen is eligible to receive milestone payments and royalties based on any product sales.
