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.

Investors face another Washington deadline

NEW YORK (Reuters) - Investors face another Washington-imposed deadline on government spending cuts next week, but it's not generating the same level of fear as two months ago when the "fiscal cliff" loomed large.

Investors in sectors most likely to be affected by the cuts, like defense, seem untroubled that the budget talks could send stocks tumbling.

Talks on the U.S. budget crisis began again this week leading up to the March 1 deadline for the so-called sequestration when $85 billion in automatic federal spending cuts are scheduled to take effect.

"It's at this point a political hot button in Washington but a very low level investor concern," said Fred Dickson, chief market strategist at D.A. Davidson & Co. in Lake Oswego, Oregon. The fight pits President Barack Obama and fellow Democrats against congressional Republicans.

Stocks rallied in early January after a compromise temporarily avoided the fiscal cliff, and the Standard & Poor's 500 index <.spx> has risen 6.3 percent since the start of the year.

But the benchmark index lost steam this week, posting its first week of losses since the start of the year. Minutes on Wednesday from the last Federal Reserve meeting, which suggested the central bank may slow or stop its stimulus policy sooner than expected, provided the catalyst.

National elections in Italy on Sunday and Monday could also add to investor concern. Most investors expect a government headed by Pier Luigi Bersani to win and continue with reforms to tackle Italy's debt problems. However, a resurgence by former leader Silvio Berlusconi has raised doubts.

"Europe has been in the last six months less of a topic for the stock market, but the problems haven't gone away. This may bring back investor attention to that," said Kim Forrest, senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.

OPTIONS BULLS TARGET GAINS

The spending cuts, if they go ahead, could hit the defense industry particularly hard.

Yet in the options market, bulls were targeting gains in Lockheed Martin Corp , the Pentagon's biggest supplier.

Calls on the stock far outpaced puts, suggesting that many investors anticipate the stock to move higher. Overall options volume on the stock was 2.8 times the daily average with 17,000 calls and 3,360 puts traded, according to options analytics firm Trade Alert.

"The upside call buying in Lockheed solidifies the idea that option investors are not pricing in a lot of downside risk in most defense stocks from the likely impact of sequestration," said Jared Woodard, a founder of research and advisory firm condoroptions.com in Forest, Virginia.

The stock ended up 0.6 percent at $88.12 on Friday.

If lawmakers fail to reach an agreement on reducing the U.S. budget deficit in the next few days, a sequester would include significant cuts in defense spending. Companies such as General Dynamics Corp and Smith & Wesson Holding Corp could be affected.

General Dynamics Corp shares rose 1.2 percent to $67.32 and Smith & Wesson added 4.6 percent to $9.18 on Friday.

EYES ON GDP DATA, APPLE

The latest data on fourth-quarter U.S. gross domestic product is expected on Thursday, and some analysts predict an upward revision following trade data that showed America's deficit shrank in December to its narrowest in nearly three years.

U.S. GDP unexpectedly contracted in the fourth quarter, according to an earlier government estimate, but analysts said there was no reason for panic, given that consumer spending and business investment picked up.

Investors will be looking for any hints of changes in the Fed's policy of monetary easing when Fed Chairman Ben Bernake speaks before congressional committees on Tuesday and Wednesday.

Shares of Apple will be watched closely next week when the company's annual stockholders' meeting is held.

On Friday, a U.S. judge handed outspoken hedge fund manager David Einhorn a victory in his battle with the iPhone maker, blocking the company from moving forward with a shareholder vote on a controversial proposal to limit the company's ability to issue preferred stock.

Papal Conclave Accompanied by Reports of Scandals and Intrigue

Osservatore Romano/Reuters

Pope Benedict XVI, right, spoke to cardinals at the Vatican on Saturday.

VATICAN CITY — As cardinals from around the world begin arriving in Rome for a conclave to elect a successor to Pope Benedict XVI, new shadows have fallen over the delicate transition, which the Vatican fears might influence the vote and with it the direction of the Roman Catholic Church.

In recent days, often speculative reports in the Italian news media — some even alleging gay sex scandals in the Vatican, others focusing on particular cardinals stung by the child sex abuse crisis — have dominated headlines, suggesting fierce internal struggles as prelates scramble to consolidate power and attack enemies in the dying days of a troubled papacy.

The reports, which the Vatican has vehemently denied, touch on some of the most vexing issues of Benedict’s reign, including the child sex abuse crisis and international criticisms of the Vatican Bank’s opaque record-keeping. The recent explosion of bad press — which some Vatican experts say is fed by carefully orchestrated leaks meant to weaken some papal contenders — also speak to Benedict’s own difficulties governing, which analysts say he is trying to address, albeit belatedly, with several high-profile personnel changes.

The drumbeat of scandal has reached such a fever pitch that on Saturday, the Vatican Secretariat of State issued a rare pointed rebuke, calling it “deplorable” that ahead of the conclave there was “a widespread distribution of often unverified, unverifiable or completely false news stories, that cause serious damage to persons and institutions.”

The Vatican compared the news reports to past attempts by foreign states to exert pressure on the papal election, saying the latest efforts to skew the choice of the next pope by trying to shape public opinion were “based on judgments that do not typically capture the spiritual aspect of the moment that the Church is living.”

Benedict had hoped to address at least one scandal with the Feb. 15 appointment of a new head of the Vatican Bank. It is less clear why he reassigned a powerful Vatican diplomatic official to a posting outside Rome, though experts say it diminishes the official’s role in helping steer Vatican policy.

On Feb. 11, Benedict made history by announcing that he would step down by month’s end. He said he was worn down by age and was resigning “in full liberty and for the good of the Church.” The volley of news reports since appeared to underscore the backbiting in the Vatican that Benedict was unable to control, and provided a hint of why he might have decided that someone younger and stronger should lead the church.

At the conclusion of the Vatican’s Lenten spiritual retreat, Cardinal Gianfranco Ravasi, the director of the Pontifical Council for Culture and a papal contender, spoke darkly of the “divisions, dissent, careerism, jealousies” that he said plagued the Vatican hierarchy.

The recent spate of news reports were linked to an earlier scandal in which the pope’s butler stole confidential documents that was considered one of the gravest security breaches in the modern history of the church.

Last week, largely unsourced articles in the center-left daily La Repubblica and the center-right weekly Panorama reported that three cardinals whom Benedict had asked last summer to investigate the leaking of the documents, known as the “VatiLeaks” scandal, had found evidence of Vatican officials who had been put in compromising positions.

The newspapers reported that, after interviewing dozens of people inside and outside the Vatican, the cardinals produced a hefty dossier. “The report is explicit. Some high prelates are subject to ‘external influence’ — we would call it blackmail — by nonchurch men to whom they are bound by ‘worldly’ ties,” La Repubblica wrote.

Vatican experts speculated that prelates eager to undermine opponents during the conclave were behind the leaks to the news media over the last week.

“The conclave is a mechanism that serves to create a dynasty in a monarchy without children, so it’s a complicated operation,” said Alberto Melloni, the director of the John XXIII Center in Bologna and the author of a book on conclaves.

This article has been revised to reflect the following correction:

Correction: February 23, 2013

An earlier version of this article misspelled the last name of a cardinal. His name is Roger M. Mahony, not Roger M. Mahoney.

From Homeless in the Congo to the Oscars Red Carpet: The Story You Must Read Before Tomorrow

Style News Now

One of the best stories from this year’s Oscars ceremony isn’t taking place on screen, but rather on the red carpet.

Rachel Mwanza, the 16-year-old star of the Best Foreign Language Film nominee War Witch, will be joining her fellow nominees in L.A. after obtaining a visa from the war-torn Democratic Republic of the Congo just days before the Oscars.

The young actress was “discovered” by the War Witch team from a documentary called Kinshasa Kids, which portrayed the life of Mwanza and other children living on the streets in the Congo.

Since being cast in the film, in which she plays a child kidnapped and enslaved to a life of guerilla warfare, her life has changed dramatically — from having a home and education paid for to winning a best actress award at the Berlin Film Festival.

And since her flight arrived late Friday night, she needed a red carpet-worthy dress quickly, which is where Rent the Runway stepped in.

The designer rental service rushed Mwanza several dresses to wear to the Independent Spirit Awards Saturday, from which she chose Kate Spade New York’s “Tiebreaker” style, adding Chamak by Priya Kakkar bangles and a Judith Leiber clutch.

“I’m so excited to be in Los Angeles. I’ve never seen the ocean before!” Mwanza tells PEOPLE through a translator. “I’m tired from my long trip, but way too excited to rest!”

She shared exclusive shots with PEOPLE (above) of her trying-on process, including shots of her caretaker “Mama” helping her zip into her final dress, and the many jewels Rent the Runway sent her to choose from.

And it didn’t take much to get Mwanza ready for her high-profile debut: “I’m going to work it on the red carpet,” she says. “I’ve been practicing my poses!”

The one disappointment from her trip so far? No sightings of a certain superstar. “Beyoncé is my favorite in the whole world. Why is she not here?!” Mwanza jokes.

Below, see a shot of Mwanza and her War Witch producers Marie-Claude Poulin and Pierre Even at the Independent Spirit Awards, and be sure to watch her film, which will be On Demand beginning Tuesday and in select theaters March 1.

And keep an eye out for her at the Oscars Sunday night, where she’ll be wearing a top-secret dress made for her by an African designer. Can’t wait to see her poses!

Scud Missile Attack Reported in Aleppo

Muzaffar Salman/Reuters

People gathered to search for survivors under rubble after what activists said was a Scud missile hit in Aleppo's Tariq al Bab neighborhood on Friday.

BEIRUT, Lebanon — Antigovernment activists in Syria said Scud missiles fired by the Syrian military slammed into at least three rebel-held districts of Aleppo on Friday, flattening dozens of houses, leaving at least 12 civilians dead and burying an undetermined number of others, perhaps dozens, under piles of rubble.

The assertion, corroborated by videos posted on the Internet, came one day after Syrian government targets in central Damascus were hit by multiple car bombings that were among the deadliest and most destructive so far in the nearly two-year-old conflict.

The reported attack on Aleppo’s Hamra, Tariq al Bab and Hanano areas with Scuds, which are not known for their accuracy, was the second time this week that the Syrian opposition has accused the military of using such missiles on Aleppo’s rebel-held areas.

Aleppo, the embattled northern city that was once Syria’s commercial capital during more peaceful times, has become one of the focal points of rebellion in the uprising against President Bashar al-Assad. On Tuesday, according to activists in Aleppo, a Syrian missile leveled part of Jabal Badro, another neighborhood controlled by the rebels, killing at least 19 people.

The Syrian Observatory for Human Rights, a Britain-based group with contacts inside Syria, said in a statement that the victims of missile explosions in Aleppo on Friday included children and that the number of victims “is expected to rise significantly because there are dozens of wounded under the rubble.”

There was no immediate mention of the Aleppo attacks by Syria’s state-run media. The Web site of Syria’s official SANA news agency was dominated by the aftermath of the car bombings that had hit central Damascus on Thursday and had left more than 70 people dead. The ferocity and scope of those bombings were unusual for central Damascus, which up until now has been largely insulated from much of the carnage and destruction wrought by the conflict in the outer Damascus suburbs and other parts of the country.

Most of the casualties in Damascus were caused by an especially powerful bomb near the headquarters of President Assad’s Baath Party and the Embassy of Russia, which were both damaged, according to witnesses contacted inside Damascus and Russian news reports. SANA said a hospital and neighboring schools also were damaged.

No group has taken responsibility for the Damascus bombings but the government has said they were carried out by terrorists, its generic description of the alliance of armed rebels seeking to depose Mr. Assad. The National Coalition of Syrian Revolutionary and Opposition Forces, the main Syrian group for the opposition which was meeting in Cairo at the time, condemned the bombings, as did its Western supporters, including the United States.

Victoria Nuland, a State Department spokeswoman, told reporters on Thursday that the United States denounces such bombings as “indiscriminate acts of violence against civilians or against diplomatic facilities, which violate international law, and we continue to emphasize that perpetrators on all sides have to be held accountable.”

Nonetheless, the bombings appeared to create a new source of diplomatic friction between the United States and Russia, which has consistently supported the Syrian government during the conflict and has rejected any proposed solution that would force Mr. Assad to relinquish power.

Russia’s mission to the United Nations accused the United States of blocking its attempt to seek approval of a Security Council statement that would have condemned the Damascus bombings as terrorism. The United States mission denied the Russian accusation, saying it had only requested that the Russian statement include a paragraph that also condemned the Syrian government’s “continued, indiscriminate use of heavy weaponry against civilians.”

Erin Pelton, a spokeswoman for the United States mission, said in news release posted Friday on its Web site that “Unfortunately, if predictably, Russia rejected the U.S. suggested language as ‘totally unacceptable’ and withdrew its draft statement.”

Other insurgency-related violence was reported by the Syrian Observatory and other activists elsewhere in Syria on Friday, including random sniping attacks in the north-central city of Raqqa that killed four people during an antigovernment demonstration, and seven people killed around a mosque in Dara’a, the southern city where the anti-Assad uprising first began in March 2011.

The Local Coordination Committees, an anti-Assad network of activists, reported that fighters from the Free Syrian Army and other groups had taken control of at least two military facilities in the suburbs of Deir al-Zour, the eastern city that has been a battleground for many months. The report, which could not be corroborated, also claimed that rebels had gained control of a missile facility in Deir al-Zour that was formerly the site of a partly built nuclear reactor bombed by Israeli warplanes in 2007. Syria disclosed the existence of the missile facility four years ago at a technical meeting of the International Atomic Energy Agency.

Hwaida Saad reported from Beirut, and Rick Gladstone from New York. David D. Kirkpatrick contributed reporting from Cairo.

They survived the Hunger Games – but will they survive the Victory Tour?

Sporting bridal-like attire, Katniss (Jennifer Lawrence and Peeta (Josh Hutcherson) pose for a promotional poster for the Victory Tour – which – in the Hunger Games universe – is when the victor of the annual Hunger Games tournament visits each of the fictional Panem's districts.

As true Hunger Games fans know, there is usually only one victor – but Katniss and Peeta rebelled against the Capitol in the first movie, originally opting for joint suicide instead of murder.

The softer look is a deliberate statement, meant to continue the charade that Katniss and Peeta were blinded by love when they rebelled against the rules in the arena.

The second film, Catching Fire, hits theaters Nov. 22.

The Lede: Syrian Television's Most Outraged Bystander

Last Update, 4:47 p.m. In the aftermath of a deadly bombing in Damascus on Thursday, a man emerged from a small knot of bystanders crowded around a camera crew from Syrian state television to vent his anger at the foreign Islamist fighters he held responsible. “We the Syrian people,” he said, “place the blame on the Nusra Front, the Takfiri oppressors and armed Wahhabi terrorists from Saudi Arabia that are armed and trained in Turkey.”

A report on Thursday’s bombing in Damascus from Syrian state television’s YouTube channel.

Pointing at the ruined street near the headquarters of President Bashar al-Assad’s ruling Baath Party, the man described the location as “a civilian place — a mosque, an elementary school, the homes of local families.”

Watching a copy of the report online, Rime Allaf, a Syrian writer monitoring the conflict from Vienna, noticed that this man on the street, whose views so closely echoed those of the Syrian government, had a very familiar face. That is because, as opposition activists demonstrated last June, the same man had already appeared at least 18 times in the forefront or background of such reports since the start of the uprising.

Man who appears on #Syria TV as “innocent bystander” with every Damascus car bomb has again appeared today. http://t.co/PmPRhzUUBN

— Rime Allaf (@rallaf) 21 Feb 13

After she posted a screenshot of the man’s latest appearance, Ms. Allaf observed on Twitter that “it would be funny if there weren’t so many victims of Syria regime terrorism!”

As The Lede noted last year, the man was even featured in two reports the same day during a small pro-Assad rally in Damascus.

Two pro-Assad television channels in Syria interviewed the same man on the street at a rally in July 2012.

Mocking the dark comedy of government-run channels recycling the same die-hard Assad supporter in so many reports, activists put together several video compilations of his appearances in the state media. The most comprehensive, posted online last June, featured excerpts from 18 reports.

A compilation of Syrian state media reports featuring the same Assad supporter again and again.

Another highlight reel, uploaded to YouTube 13 months ago by a government critic, showed that after the man had spoken at least five times on state-run television, he appeared in the background of a BBC report wearing a military uniform.

A man who is frequently interviewed on Syrian state television in civilian dress appeared in the background of a BBC report wearing a military uniform.

As longtime readers of The Lede may recall, during the dispute over Iran’s 2009 presidential election, opposition bloggers noticed that one particularly die-hard supporter of Mahmoud Ahmadinejad also appeared again and again and again in photographs of pro-government rallies.

While there is no way to determine just who is responsible for Syrian television’s frequent interviews with this same man on the street, there is some evidence that Iran has advised Syria on how to report bombings on state television.

Last year, when The Guardian published a trove of hacked e-mails taken from the in-boxes of Syrian officials, one message forwarded to the president appeared to include advice from Iranian state television’s bureau chief in Damascus on what his Syrian counterparts should report after bombings. That e-mail, from Hussein Mortada, a Lebanese journalist who runs coverage of Syria for the Iranian government’s satellite news channels, complained that the government was not heeding directions he had received “from Iran and Hezbollah,” the Lebanese militant group, about who Syria should blame for bomb attacks. “It is not in our interest to say that Al Qaeda is behind” every bombing, Mr. Mortada wrote, “because such statements clear the U.S. administration and the Syrian opposition of any responsibility.”

Do the Hemsworth Brothers Have a Type?

AKM-GSI (2)

Miley Cyrus has been very open about fiancé Liam Hemsworth’s fondness for her bold new do — and he’s obviously a fan of her increasingly funky ensembles as well.

And now that we’ve spotted Hemsworth’s brother Chris out with his wife, Elsa Pataky, who’s rocking a Cyrus-esque ensemble herself, we have to wonder: do the Hemsworth boys have a type?

Both of the Aussie hotties’ significant others share an affinity for shredded denim, chunky engineer boots and choppy, super-short blonde hair.

And when we spotted the tiny girls standing next to the bulky brothers, both clad in V-necks, slouchy jeans and aviators, we admit we had to do a double take to deduce which couple was which.

Fortunately, Chris travels with the ultimate accessory — his adorable baby daughter — which makes them a bit easier to tell apart. But we still have to guess there’s a lot of confusion around the Hemsworth household at holidays.

Tell us: Do you and your siblings go for the same “type?” Are you amused that the Hemsworth boys seem to?

Flu shot doing a poor job of protecting elderly

ATLANTA (AP) — It turns out this year's flu shot is doing a startlingly dismal job of protecting senior citizens, the most vulnerable age group.

The vaccine is proving only 9 percent effective in people 65 and older against the harsh strain of the flu that is predominant this season, the Centers for Disease Control and Prevention said Thursday.

Health officials are baffled as to why this is so. But the findings help explain why so many older people have been hospitalized with the flu this year.

Despite the findings, the CDC stood by its recommendation that everyone over 6 months get flu shots, the elderly included, because some protection is better than none, and because those who are vaccinated and still get sick may suffer less severe symptoms.

"Year in and year out, the vaccine is the best protection we have," said CDC flu expert Dr. Joseph Bresee.

Overall, across the age groups studied, the vaccine's effectiveness was found to be a moderate 56 percent, which means those who got a shot have a 56 percent lower chance of winding up at the doctor with the flu. That is somewhat worse than what has been seen in other years.

For those 65 and older, the vaccine was only 27 percent effective against the three strains it is designed to protect against, the worst level in about a decade. It did a particularly poor job against the tough strain that is causing more than three-quarters of the illnesses this year.

It is well known that flu vaccine tends to protect younger people better than older ones. Elderly people have weaker immune systems that don't respond as well to flu shots, and they are more vulnerable to the illness and its complications, including pneumonia.

But health officials said they don't know why this year's vaccine did so poorly in that age group.

One theory, as yet unproven, is that older people's immune systems were accustomed to strains from the last two years and had more trouble switching gears to handle this year's different, harsh strain.

The preliminary data for senior citizens is less than definitive. It is based on fewer than 300 people scattered among five states.

But it will no doubt surprise many people that the effectiveness is that low, said Michael Osterholm, a University of Minnesota infectious-disease expert who has tried to draw attention to the need for a more effective flu vaccine.

Among infectious diseases, flu is considered one of the nation's leading killers. On average, about 24,000 Americans die each flu season, according to the CDC.

This flu season started in early December, a month earlier than usual, and peaked by the end of year. Hospitalization rates for people 65 and older have been some of the highest in a decade, at 146 per 100,000 people.

Flu viruses tend to mutate more quickly than others, so a new vaccine is formulated each year to target the strains expected to be the major threats. CDC officials have said that in formulating this year's vaccine, scientists accurately anticipated the strains that are circulating this season.

Because of the guesswork involved, scientists tend to set a lower bar for flu vaccine. While childhood vaccines against diseases like measles are expected to be 90 or 95 percent effective, a flu vaccine that's 60 to 70 percent effective in the U.S. is considered pretty good. By that standard, this year's vaccine is OK.

For senior citizens, a flu vaccine is considered pretty good if it's in the 30 to 40 percent range, said Dr. Arnold Monto, a University of Michigan flu expert.

A high-dose version of the flu shot was recently made available for those 65 and older, but the new study was too small to show whether that has made a difference.

The CDC estimates are based on about 2,700 people who got sick in December and January. The researchers traced back to see who had gotten shots and who hadn't. An earlier, smaller study put the vaccine's overall effectiveness at 62 percent, but other factors that might have influenced that figure weren't taken into account.

The CDC's Bresee said there is a danger in providing preliminary results because it may result in people doubting — or skipping — flu shots. But the figures were released to warn older people who got shots that they may still get sick and shouldn't ignore any serious flu-like symptoms, he said.
