Input: Consider Input: Paragraph: Although Pfizer continues to test the drug, called dacomitinib, in another Phase III study, hopes for its success have now largely faded, according to ISI Group analyst Mark Schoenebaum. "We believe consensus expectations (for the drug) will be close to zero given today's readout" of unsuccessful trial results, Schoenebaum said in a research note. In one of the failed trials, called ARCHER 1009, patients given Pfizer's once-daily pill did not show improved survival without the cancer worsening, compared with Roche Holding AG's widely used Tarceva (erlotinib). Tarceva is the current standard of care in patients with mutated forms of a protein called Epidermal Growth Factor Receptor (EGFR). The protein plays a role in normal regulation of cell growth, but when mutated is believed to cause cells to proliferate and thereby help spur various types of cancer. Dacomitinib is designed to block several types of Epidermal Growth Factor receptors, while Tarceva and similar treatments for lung cancer target only one type of receptor. Cowen and Co had forecast annual sales of $500 million by 2020 for dacomitinib, if it were approved for lung cancer. That would make it a moderate-sized product for Pfizer, the largest U.S. drugmaker, which has annual revenue of $50 billion. Schoenebaum said there has been little investor interest in the drug and that Wall Street had expected it to generate annual sales of only $300 million by 2018. The second failed trial, named BR.26, involved patients that previously had failed to benefit from chemotherapy as well as from treatment with an EGFR inhibitor. Overall survival of patients taking the Pfizer drug was not prolonged in the study, compared with patients given a placebo. Pfizer said adverse events seen with dacomitinib were consistent with those seen in smaller earlier studies. In the meantime, Pfizer said dacomitinib is also being tested in a third late-stage trial, called ARCHER 1050, among patients with advanced non-small cell lung cancer who have not received prior treatment. The study will compare dacomitinib with Iressa (gefitinib), an EGFR inhibitor sold by AstraZeneca Plc. Results from that study are expected in 2015. Pfizer shares were little changed in morning trading on the New York Stock Exchange. Claim: Pfizer lung cancer drug fails in two large studies.

Output: Pfizer Inc on Monday said one of its experimental drugs had failed to meet its goals in two late-stage studies among patients who had received prior treatment for advanced non-small cell lung cancer, the most common form of the disease.

Input: Consider Input: Paragraph: On 10 June 2016, theDaily Beastreported that Sen. David Perdue urged attendees of the Faith & Freedom Coalition's Road to Majority conferenceto pray for misfortune and death to befall President Barack Obama: At a major event for conservative Christians this morning, a Republican senator joked about praying for President Obama's "days to be short." Sen. David Perdue, a freshman senator from Georgia, opened his remarks at the Faith & Freedom Coalition's Road to Majority conference by encouraging attendees to pray for President Obama. But, he added in a joking tone, they need to pray for him in a very specific way: "We should pray for him like Psalms 109:8 says: Let his days be few, and let another have his office," the senator said, smiling wryly. The crowd chuckled and he moved on with his address. The rest of that passage, which Perdue did not recite, reads, "May his children be fatherless and his wife a widow. May his children be wandering beggars; may they be driven from their ruined homes." The psalm is a pointed, lengthy death wish for one of David's enemies. Video depicted Purdue's 10 June 2016 remarks: Psalms 109:8 (alternately named "Song of the Slandered") was rendered in the manner below in the King James Bible: Hold not thy peace, O God of my praise; For the mouth of the wicked and the mouth of the deceitful are opened against me: they have spoken against me with a lying tongue. They compassed me about also with words of hatred; and fought against me without a cause. For my love they are my adversaries: but I give myself unto prayer. And they have rewarded me evil for good, and hatred for my love. Set thou a wicked man over him: and let Satan stand at his right hand. When he shall be judged, let him be condemned: and let his prayer become sin. Let his days be few; and let another take his office. Let his children be fatherless, and his wife a widow. Let his children be continually vagabonds, and beg: let them seek their bread also out of their desolate places. Let the extortioner catch all that he hath; and let the strangers spoil his labour. Let there be none to extend mercy unto him: neither let there be any to favour his fatherless children. Let his posterity be cut off; and in the generation following let their name be blotted out. Let the iniquity of his fathers be remembered with the LORD; and let not the sin of his mother be blotted out. Let them be before the LORD continually, that he may cut off the memory of them from the earth. As many pointed out, the Senator's Biblical reference wasn'ta newor even uncommon scripture-based jab at President Obama. A 2009 articlereported that the verse was traction across the internet as a veiled threat cloaked in the guise of prayerful intent: There's a new slogan making its way onto car bumpers and across the Internet. It reads simply: "Pray for Obama: Psalm 109:8" A nice sentiment? Maybe not. The psalm reads, "Let his days be few; and let another take his office." Presidential criticism through witty slogans is nothing new. Bumper stickers, t-shirts, and hats with "1/20/09" commemorated President Bush's last day in office. But the verse immediately following the psalm referenced is a bit more ominous: "Let his children be fatherless, and his wife a widow." The slogan comes at a time of heightened concern about antigovernment anger. Earlier this year, the president's senior adviser, David Axelrod, said that Tea Parties could lead to something unhealthy. In September, authorities shut down a poll on Facebook asking if President Obama should be killed. Still, that doesn't push the Psalms citation into the realm of hate speech, says Chris Hansen, a staff attorney with the American Civil Liberties Union (ACLU). That particular piece was published during President Obama's first term in office. Some argued at the time that the reference to the versesimply expressed a hope that he not be re-elected to a second term: Deborah Lauter, director of civil rights at the Anti-Defamation League agrees that the bumper sticker falls within acceptable political discourse. "The problem is you don't know if people who are donning that message in a shirt or on a bumper sticker are fully aware of the quote or what follows. Obviously that message makes the ambiguity disappear. If they're just referring to him being out of office, that's one thing. If they're referring to him being dead, that's so offensive. It's protected speech, but it's clearly offensive." However, that motive ceased to be relevant after Obama's 2012 re-election. A representative for the Senator provided a terse statement to a Bloomberg reporter about the controversy: David Perdue spokeswoman Caroline Vanvick responds in an email: "He in no way wishes harm towards our president" pic.twitter.com/PPj5jtZv0n Sahil Kapur (@sahilkapur) June 10, 2016 The statementread: Senator Perdue said we are called to pray for our country, for our leaders, and for our president. He in no way wishes harm towards our president and everyone in the room understood that. However, we should add the media to our prayer list because they are pushing a narrative to create controversy and this is exactly what the American people are tired of. It istrue Sen. David Perdue laughed and referenced Psalms 109:8 during a 10 June 2016 conservative Christian event. A representative for the Senator addressed the ensuing controversy, blaming the media for "pushing a narrative" forthe outcry. Claim: Sen. David Perdue advised attendees to offer up an ominous prayer aimed at President Obama during the 2016 Faith & Freedom Coalition's Road to Majority conference.

Output: What's true: Sen. David Perdue referenced Psalms 109:8 at an event; Perdue's representative later denied he wished death on the President. What's false: Sen. Perdue didn't explicitly state attendees at the conference should pray expressly for the President to die.

Input: Consider Input: Paragraph: Roughly half of Yellowstone's 4,600 bison are estimated to have been exposed to brucellosis, a bacterial infection that can sometimes cause cows and bison to miscarry. Worries that infected bison may endanger cattle in states such as Montana that border Yellowstone had prompted the powerful ranching lobby to endorse biobullets - absorbable projectiles packed with vaccine. They would cut disease rates among bison by as much as 35 percent over 30 years. The proposal was the latest decades-long efforts to ease conflicts between livestock interests and wildlife advocates over management of Yellowstone bison. Park officials said they decided against the remote vaccination program because of its $9 million price tag, questions about its effectiveness and the possible impact on the millions of visitors who flock to the park to view iconic Western wildlife like bison. The measure would have required shooting the animals once a year for three decades, raising questions about how increased human interaction could affect bison within the wild herd. "We have concerns about how that repeated contact might impact bison behavior and their visibility to park visitors," said Yellowstone spokesman Al Nash. Nash said there was no documented case of wild bison transmitting brucellosis to cattle, which he said signifies the success of existing measures designed to separate the park's herd from domestic livestock. Those practices include returning bison that leave the park, testing and vaccinating bison that leave Yellowstone, and slaughtering some infected animals. Errol Rice, executive vice president of the Montana Stockgrowers Association, said the threats posed by infected bison to Montana's brucellosis-free certification, which protects the market value of cattle, warranted using biobullets. He said the program would have lessened the public outcry that erupts when wandering bison are corralled and shipped to slaughterhouses. "The capture and removal of bison has been a challenging issue for the park and Montana. Remote vaccination would have helped alleviate the public relations burden we have to deal with when bison migrate out of Yellowstone," he said. Stephany Seay, spokeswoman for Buffalo Field Campaign, a bison advocacy group, applauded the park's decision not to shoot bison with vaccine. "It was a mismanagement scheme based on a livestock model. We don't vaccinate skunks against rabies or mosquitoes against West Nile virus," she said. Claim: Yellowstone managers reject vaccinating bison with biobullets.
Output: Yellowstone National Park managers have rejected a plan to use air rifles to shoot the nation's last herd of purebred bison with so-called biobullets containing a vaccine against a cattle disease, in a decision that has riled the U.S. livestock industry.
