FDA approves new targeted breast cancer drug

WASHINGTON (AP) — The Food and Drug Administration has approved a first-of-a-kind breast cancer medication that targets tumor cells while sparing healthy ones.

The drug Kadcyla from Roche combines the established drug Herceptin with a powerful chemotherapy drug and a third chemical linking the medicines together. The chemical keeps the cocktail intact until it binds to a cancer cell, delivering a potent dose of anti-tumor poison.

Cancer researchers say the drug is an important step forward because it delivers more medication while reducing the unpleasant side effects of chemotherapy.

"This antibody goes seeking out the tumor cells, gets internalized and then explodes them from within. So it's very kind and gentle on the patients — there's no hair loss, no nausea, no vomiting," said Dr. Melody Cobleigh of Rush University Medical Center. "It's a revolutionary way of treating cancer."

Cobleigh helped conduct the key studies of the drug at the Chicago facility.

The FDA approved the new treatment for about 20 percent of breast cancer patients with a form of the disease that is typically more aggressive and less responsive to hormone therapy. These patients have tumors that overproduce a protein known as HER-2. Breast cancer is the second most deadly form of cancer in U.S. women, and is expected to kill more than 39,000 Americans this year, according to the National Cancer Institute.

The approval will help Roche's Genentech unit build on the blockbuster success of Herceptin, which has long dominated the breast cancer marketplace. The drug had sales of roughly $6 billion last year.

Genentech said Friday that Kadcyla will cost $9,800 per month, compared to $4,500 per month for regular Herceptin. The company estimates a full course of Kadcyla, about nine months of medicine, will cost $94,000.

FDA scientists said they approved the drug based on company studies showing Kadcyla delayed the progression of breast cancer by several months. Researchers reported last year that patients treated with the drug lived 9.6 months before death or the spread of their disease, compared with a little more than six months for patients treated with two other standard drugs, Tykerb and Xeloda.

Overall, patients taking Kadcyla lived about 2.6 years, compared with 2 years for patients taking the other drugs.

FDA specifically approved the drug for patients with advanced breast cancer who have already been treated with Herceptin and taxane, a widely used chemotherapy drug. Doctors are not required to follow FDA prescribing guidelines, and cancer researchers say the drug could have great potential in patients with earlier forms of breast cancer

Kadcyla will carry a boxed warning, the most severe type, alerting doctors and patients that the drug can cause liver toxicity, heart problems and potentially death. The drug can also cause severe birth defects and should not be used by pregnant women.

Kadcyla was developed by South San Francisco-based Genentech using drug-binding technology licensed from Waltham, Mass.-based ImmunoGen. The company developed the chemical that keeps the drug cocktail together and is scheduled to receive a $10.5 million payment from Genentech on the FDA decision. The company will also receive additional royalties on the drug's sales.

Shares of ImmunoGen Inc. rose 2 cents to $14.32 in afternoon trading. The stock has ttraded in a 52-wek range of $10.85 to $18.10.

Wall Street ends lower on growth worries

NEW YORK (Reuters) - U.S. stocks fell for a second straight day on Thursday and the S&P 500 posted its worst two-day loss since November after reports cast doubt over the health of the U.S. and euro-zone economies.

But a late-day rally helped stocks erase some of their losses with most of the pullback concentrated in the technology- heavy Nasdaq. The move suggested investors were still willing to buy on dips even after the sharp losses in the last session.

In Europe, business activity indexes dealt a blow to hopes that the euro zone might emerge from recession soon, showing the downturn across the region's businesses unexpectedly grew worse this month.

"The PMI numbers out of Europe were really a blow to the market," said Jack De Gan, chief investment officer at Harbor Advisory in Portsmouth, New Hampshire. "The market was expecting signs that recovery is still there, but the numbers just highlighted that the euro-zone problem is still persistent."

U.S. initial claims for unemployment benefits rose more than expected last week while the Federal Reserve Bank of Philadelphia said its index of business conditions in the U.S. mid-Atlantic region fell in February to the lowest in eight months.

Gains in Wal-Mart Stores Inc shares helped cushion the Dow. The shares gained 1.5 percent to $70.26 after the world's largest retailer reported earnings that beat expectations, though early February sales were sluggish.

The Dow Jones industrial average <.dji> fell 46.92 points, or 0.34 percent, to 13,880.62 at the close. The Standard & Poor's 500 Index <.spx> lost 9.53 points, or 0.63 percent, to 1,502.42. The Nasdaq Composite Index <.ixic> dropped 32.92 points, or 1.04 percent, to close at 3,131.49.

The two-day decline marked the U.S. stock market's first sustained pullback this year. The Standard & Poor's 500 has fallen 1.8 percent over the period and just managed to hold the 1,500 level on Thursday. Still, the index is up 5.3 percent so far this year.

The abrupt reversal in markets, which started on Wednesday after minutes from the Federal Reserve's January meeting suggested stimulus measures may end earlier than thought, looks set to halt a seven-week winning streak for stocks that had lifted the Dow and the S&P 500 close to all-time highs.

Wall Street will soon face another test with the upcoming debate in Washington over the automatic across-the-board spending cuts put in place as part of a larger congressional budget fight. Those cuts, set to kick in on March 1 unless lawmakers agree on an alternative, could depress the economy.

Semiconductor stocks ranked among the weakest of the day, pressuring the Nasdaq as the Philadelphia Semiconductor Index <.sox> fell 1.8 percent. Intel Corp fell 2.3 percent to $20.25 while Advanced Micro Devices lost 3.7 percent to $2.60 as the S&P 500's biggest percentage decliner.

The Dow also got a helping hand from personal computer maker Hewlett-Packard Co , which rose 2.3 percent to end the regular session at $17.10. The company was scheduled due to report first-quarter results after the closing bell.

Shares of Boeing Co rose 1.6 percent to $76.01 as a senior executive was set to meet with the head of the U.S. Federal Aviation Administration on Friday and present a series of measures to prevent battery failures that grounded its 787 Dreamliner fleet, according to a source familiar with the plans.

In other company news, shares of supermarket operator Safeway Inc jumped 14.1 percent to $22.97 after the company reported earnings that beat expectations.

Shares of VeriFone Systems Inc tumbled nearly 43 percent to $18.24 after the credit-card swipe machine maker forecast first- and second-quarter profits well below expectations.

Of the 427 companies in the S&P 500 that have reported results so far, 69.3 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters, according to Thomson Reuters data through Thursday morning.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.9 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Berry Petroleum Co jumped 19.3 percent to $46.02 after oil and gas producer Linn Energy LLC said it would buy the company in an all-stock deal valued at $4.3 billion, including debt. Linn Energy shares advanced 2.8 percent to $37.68.

About two stocks fell for everyone that rose on the New York Stock Exchange and Nasdaq. About 7.64 billion shares changed hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, well above the 20-day moving average of around 6.6 billion shares.

Montevideo Journal: Uruguay’s Video Game Start-Ups Garner Attention

MONTEVIDEO, Uruguay — For a start-up that has a hit video game for the iPhone, the new loft-style offices of Ironhide Game Studio are exactly what one would expect — a newly hired staff labors feverishly on software updates not far from a pinball machine and custom-built monster arcade cabinet intended for letting off steam.

But the company, a success in the fiercely competitive field of video game development, stands out from other high-tech ventures in one respect: its unconventional location, which frequently confuses people abroad. “They politely ask, ‘Where is Uruguay?’ ” said Álvaro Azofra, one of the three founders of Ironhide, the company behind Kingdom Rush, a lucratively popular game in the United States that involves a cartoonish kingdom under attack by marauding yetis and ogres.

Squeezed between Brazil and Argentina and long dependent on commodities exports, Uruguay may be better known for its flocks of sheep and herds of cattle. But attention is now shifting to the country’s growing constellation of start-ups that are engineering video games for computers and hand-held devices.

Developers point to a variety of reasons that Uruguay has been able to compete with South America’s larger economies, whether the creativity of its engineers and commercial artists or its relatively relaxed immigration rules and extensive use of computers in schools.

“It’s ironic, because historically, this is a country that hates entrepreneurship, but not the culture of entrepreneurship,” said Gonzalo Frasca, a video game theorist whose company, Powerful Robot, has developed numerous games for clients in the United States, including Legends of Ooo, based on the Cartoon Network animated television series “Adventure Time.”

Mr. Frasca, 40, contrasted the skepticism that persists in relation to private enterprise in Uruguay’s cradle-to-grave welfare state, in which companies in sectors like telecommunications, casinos and even whiskey production remain under state control, with the country’s robust tradition of creativity in the arts and sciences.

“We still have strong schools for computer science,” said Mr. Frasca, who has a doctorate in video game studies from IT University of Copenhagen and is a pioneer in Uruguay’s game industry. “When people graduate, they realize they’re in a small country where they have no choice but to engage with the rest of the world.”

While ORT, Uruguay’s largest private university, offers one of the region’s first degrees in video game design, the relaxed atmosphere of seaside Montevideo — the Uruguayan writer Eduardo Galeano once remarked that his countrymen resembled “Argentines on Valium” — can still make it seem as if it would be an unlikely place for technology start-ups to thrive.

Other parts of Latin America are nurturing their own video game development scenes. Chile, for instance, recently drew attention when Atakama Labs, a game developer based in Santiago, was acquired by the Japanese gaming company DeNA.

Gaming studios have also emerged in São Paulo and Rio de Janeiro, Brazil’s two largest cities, but developers there complain of byzantine tax regulations and labor rules that make hiring employees costlier than in some rich industrialized countries. In Argentina, dozens of game-developing start-ups have been founded in Buenos Aires.

But while Argentina has traditionally had more companies in the industry, some of the momentum is seen shifting across the border to Uruguay as Argentine ventures struggle with abrupt changes in economic policy, including the tightening of currency controls that have complicated operations for exporters.

In Latin America and beyond, developers are seeking to mimic the success of Kingdom Rush, ranked in 2012 among the top-selling paid applications for the iPhone in the United States. In addition to Ironhide and Powerful Robot, an array of other game developers operates quietly.

Some, like Trojan Chicken, a developer of educational games in Spanish for schoolchildren, benefit from the heavy presence of the state across Uruguay’s economy, which avoided the privatization wave of neighboring Latin American countries in the 1990s.

Ingenio, a state-controlled incubator for start-ups, helped finance Trojan Chicken, which has created educational games including 1811, an adventure game set in colonial Uruguay, and D.E.D., a detective game in which players solve thefts of national heritage. The games are designed to be played on the inexpensive laptops distributed to schoolchildren across Uruguay.

Nearly all of the 300,000 children in Uruguay’s public schools now have their own computers, after the authorities here began embracing One Laptop per Child, the ambitious project aimed at bringing computing to children in the developing world, in 2006. Called the Plan Ceibal here, it is financed by public money.

Miguel Brechner, the director of the Plan Ceibal, said the initiative was already serving as a catalyst for Uruguayan content developers, notably gaming and animation studios. Describing Ceibal as a “digital equality plan,” he said that “reality has shown that kids get excited about games.”

Encompassing the video game companies, software development in Uruguay has evolved into a $600 million industry, making the country Latin America’s leader in per-capita software exports. But some here say that the industry may also be falling victim to its success, as salaries for developers rapidly climb and make it more expensive for start-ups to compete internationally.

Still, Uruguay’s immigration laws offer certain advantages in the competition for talented employees. Building on a history of attracting immigrants from Europe, engineers, animators and other foreign hires at start-ups can legally reside and work in Uruguay while their applications for work visas are being processed.

“Uruguay is a remarkably open place when it comes to attracting talent,” said Evan Henshaw-Plath, an American among the founders of the company that became Twitter. After moving to Uruguay in 2007, Mr. Henshaw-Plath founded a software development company that now has employees from countries like Poland and Ecuador.

Drawing a contrast between Uruguay and Brazil, he delights in telling a story about an American technology investor based in Japan who was about to embark on a business trip to South America aimed at finding start-ups in which to invest or to acquire outright.

Upon discovering that Brazil required Americans to go through a bureaucratic ordeal to obtain a visa, the investor canceled his trip there. Instead, he visited Uruguay, which has no such visa requirements, and eventually acquired Mr. Henshaw-Plath’s 20-person company, Cubox.

APNewsBreak: Govs to hear Oregon health care plan

SALEM, Ore. (AP) — Oregon Gov. John Kitzhaber will brief other state leaders this weekend on his plan to lower Medicaid costs, touting an overhaul that President Barack Obama highlighted in his State of the Union address for its potential to lower the deficit even as health care expenses climb.

The Oregon Democrat leaves for Washington, D.C., on Friday to pitch his plan that changes the way doctors and hospitals are paid and improves health care coordination for low income residents so that treatable medical problems don't grow in severity or expense.

Kitzhaber says his goal is to win over a handful of other governors from each party.

"I think the politics have been dialed down a couple of notches, and now people are willing to sit down and talk about how we can solve the problem" of rising health care costs, Kitzhaber told The Associated Press in a recent interview.

Kitzhaber introduced the plan in 2011 in the face of a severe state budget deficit, and he's been talking for two years about expanding the initiative beyond his state. Now, it seems he's found people ready to listen.

Hospital executives from Alabama visited Oregon last month to learn about the effort. And the U.S. Department of Health and Human Services announced Thursday that it's giving Oregon a $45 million grant to help spread the changes beyond the Medicaid population and share information with other states, making it one of only six states to earn a State Innovation Model grant.

Kitzhaber will address his counterparts at a meeting of the National Governors Association. His talk isn't scheduled on the official agenda, but a spokeswoman confirmed that Kitzhaber is expected to present.

"The governors love what they call stealing from one another — taking the good ideas and the successes of their colleagues and trying to figure out how to apply that in their home state," said Matt Salo, director of the National Association of Medicaid Directors.

There's been "huge interest" among other states in Oregon's health overhaul, Salo said, not because the concepts are brand new, but because the state managed to avoid pitfalls that often block health system changes.

Kitzhaber persuaded state lawmakers to redesign the system of delivering and paying for health care under Medicaid, creating incentives for providers to coordinate patient care and prevent avoidable emergency room visits. He has long complained that the current financial incentives encourage volume over quality, driving costs up without making people healthier.

Obama, in his State of the Union address this month, suggested that changes such as Oregon's could be part of a long-term strategy to lower the federal debt by reigning in the growing cost of federally funded health care.

"We'll bring down costs by changing the way our government pays for Medicare, because our medical bills shouldn't be based on the number of tests ordered or days spent in the hospital — they should be based on the quality of care that our seniors receive," Obama said.

The Obama administration has invested in the program, putting up $1.9 billion to keep Oregon's Medicaid program afloat over the next five years while providers make the transition to new business models and incorporate new staff and technology.

In exchange, though, the state has agreed to lower per-capita health care cost inflation by 2 percentage points without affecting quality.

The Medicaid system is unique in each state, and Kitzhaber isn't suggesting that other states should adopt Oregon's specific approach, said Mike Bonetto, Kitzhaber's health care policy adviser. Rather, he wants governors to buy into the broad concept that the delivery system and payment models need to change.

That's not a new theory. But Oregon has shown that under the right circumstances massive changes to deeply entrenched business models can gain wide support.

What Oregon can't yet show is proof the idea is working — that it's lowering costs without squeezing on the quality or availability of care. The state is just finishing compiling baseline data that will be used as a basis of comparison.

One factor driving the Obama administration's interest in Oregon's success is the president's health care overhaul. Under the Affordable Care Act, millions more Americans will join the Medicaid rolls after Jan. 1, and the health care system will have to be able to absorb the influx of patients in a logistically and financially sustainable way.

The federal government will pay 100 percent of the costs for those additional patients in the first three years before scaling back to 90 percent in 2020 and beyond.

"There are a lot of governors who are facing the same challenges we're facing in Oregon," Kitzhaber said. "They recognize that the cost of health care is something they're going to have to get their arms around."

World Briefing | Africa: Nigeria: Security Service Says It Halted Group Watching Israeli and U.S. Targets

Nigeria’s State Security Service said Wednesday that it broke up what it characterized as a terrorist group, backed by “Iranian handlers,” that wanted to gather intelligence about locations frequented by Americans and Israelis. The service said it arrested three suspects, but one remained at large. A spokeswoman, Marilyn Ogar, who was reading from a statement, identified the head of the group as Abdullahi Mustaphah Berende, a leader of a local Shiite sect. “He personally took photographs of the Israeli culture center in Ikoyi, Lagos,” she said. The group also conducted surveillance on USAID and the United States Peace Corps, she said. Ms. Ogar did not take questions.

Why This 7-Year-Old Is the Doogie Howser of Videogame Design

It’s not unusual for a seven-year-old girl to dream of being a ballerina, but it’s unheard of for a child so young to design a computer game about it. Nonetheless, first-grader and computer science prodigy Zora Ball did just that, making her quite possibly the youngest videogame programmer ever.

Using an open-source software program called Bootstrap, the primary school student designed a mobile game app she titled Vampire Diamonds. In it, the player takes on the role of the main protagonist, a ballerina, whose goal is to search for a jewel that’s hidden in a nail salon, while trying to avoid an evil vampire.

The game debuted at FATE’s Bootstrap Expo last year and while widely acclaimed, some were suspicious that the first-grader may have secretly received help—most likely from her older brother, Trace Ball, a STEM Scholar of the Year. To prove them wrong, the seven-year-old reportedly reconfigured her app on the spot.

Bootstrap, and its functional programming language Racket, are usually taught to kids between the ages of 12-16 as a way to use videogame development to teach algebraic concepts to students. Zora learned it in an after-school program run by the educational nonprofit known as FATE, or The Foundation for the Advancement of Technology in Education.

Kelly Ohlert, FATE’s executive director, tells TakePart, “While Zora was able to follow the directions in order to write the code for her game, everything we know about cognitive psychology indicates that a seven year-old probably can’t yet comprehend the curriculum-based algebra that is the heart of Bootstrap. That being said, she understood enough of the coding side to make simple changes to her game upon request, which is huge.”

FATE’s mission is to promote the skilled and intelligent use of education technology. Ohlert tells TakePart, “Specifically, we are targeting the problem of not having enough students trained in science, technology, engineering and mathematics (STEM) to meet the needs of the next-generation workforce.

According to the Brookings Institute, the U.S. is already suffering from a lack of professionals qualified for STEM careers. Part of that lack comes from the fact that so few women are involved in science-based professions. That’s why tech companies are targeting girls and young women for more education and employment opportunities. In addition to FATE, which targets boys and girls alike, Microsoft sponsors DigiGirlzHighTech Camp, “Girls Who Code” offers free summer workshops to female high school students, and Womens’ Tech Connect mentors young computer scientists involved in the science education program through NetHope.

While Zora Ball is still too young to think of her new role as the poster child for girls in science, her recent accomplishment is another kick in the slowly opening door for girls to embrace STEM-based fields.

Scientists use 3-D printing to help grow an ear

WASHINGTON (AP) — Printing out body parts? Cornell University researchers showed it's possible by creating a replacement ear using a 3-D printer and injections of living cells.

The work reported Wednesday is a first step toward one day growing customized new ears for children born with malformed ones, or people who lose one to accident or disease.

It's part of the hot field of tissue regeneration, trying to regrow all kinds of body parts. Scientists hope using 3-D printing technology might offer a speedier method with more lifelike results.

If it pans out, "this enables us to rapidly customize implants for whoever needs them," said Cornell biomedical engineer Lawrence Bonassar, who co-authored the research published online in the journal PLoS One.

This first-step work crafted a human-shaped ear that grew with cartilage from a cow, easier to obtain than human cartilage, especially the uniquely flexible kind that makes up ears. Study co-author Dr. Jason Spector of Weill Cornell Medical Center is working on the next step — how to cultivate enough of a child's remaining ear cartilage in the lab to grow an entirely new ear that could be implanted in the right spot.

Wednesday's report is "a nice advancement," said Dr. Anthony Atala, director of the Institute for Regenerative Medicine at Wake Forest Baptist Medical Center, who wasn't involved in the new research.

Three-dimensional printers, which gradually layer materials to form shapes, are widely used in manufacturing. For medicine, Atala said the ear work is part of broader research that shows "the technology now is at the point where we can in fact print these 3-dimensional structures and they do become functional over time."

Today, people who need a new ear often turn to prosthetics that require a rod to fasten to the head. For children, doctors sometimes fashion a new ear from the stiffer cartilage surrounding ribs, but it's a big operation. Spector said the end result seldom looks completely natural. Hence the quest to use a patient's own cells to grow a replacement ear.

The Cornell team started with a 3-D camera that rapidly rotates around a child's head for a picture of the existing ear to match. It beams the ear's geometry into a computer, without the mess of a traditional mold or the radiation if CT scans were used to measure ear anatomy.

"Kids aren't afraid of it," said Bonassar, who used his then-5-year-old twin daughters' healthy ears as models.

From that image, the 3-D printer produced a soft mold of the ear. Bonassar injected it with a special collagen gel that's full of cow cells that produce cartilage — forming a scaffolding. Over the next few weeks, cartilage grew to replace the collagen. At three months, it appeared to be a flexible and workable outer ear, the study concluded.

Now Bonassar's team can do the process even faster by using the living cells in that collagen gel as the printer's "ink." The 3-D technology directly layers the gel into just the right ear shape for cartilage to cover, without having to make a mold first.

The next step is to use a patient's own cells in the 3-D printing process. Spector, a reconstructive surgeon, is focusing on children born without a fully developed external ear, a condition called microtia. They have some ear cartilage-producing cells in that tissue, just not enough. So he's experimenting with ways to boost those cells in the lab, "so we can grow enough of them from that patient to make an ear," he explained.

That hurdle aside, cartilage may be the tissue most amenable to growing with the help of 3-D printing technology, he said. That's because cartilage doesn't need blood vessels growing inside it to survive.
