2012年12月29日讯 /生物谷BIOON/ --由Bristol-Myers Squibb(BMS)公司和Pfizer公司研制的治疗心房颤动的新药Eliquis获得FDA批准。

心房颤动是一种常见的心律不齐症,大约有580万美国人患有此症,研究显示,Eliquis能够大大降低发病的风险。据估计,Eliquis一旦上市,销售额最高可达50亿美元。

因为该药的巨大市场,此前欧洲、日本、加拿大都已经先后批准了该药进入其市场。美国FDA在七月份收到申请后,要求两公司再提供Eliquis更进一步的数据,直至今日才获得批准。(生物谷Bioon.com)

详细英文报道:

The FDA saved one of its biggest approvals of the year until the end of 2012. Eliquis, the clot buster from Bristol-Myers Squibb ($BMY) and Pfizer ($PFE), garnered the agency's stamp for use in certain patients with atrial fibrillation.

Bristol and Pfizer--which have suffered from generic competition to the big-selling meds Plavix and Lipitor, respectively--have now won approval for the most lucrative use of the drug in the world's top healthcare market. The FDA sanctioned the bloodthinner for reducing risk of stroke and blood clots in patients with non-valvular atrial fibrillation, saying that the drug shouldn't be used in patients with artificial heart valves or defective heart valves.

Atrial fibrillation (AF), a common irregular heart beat, afflicts more than 5.8 million Americans, according the Bristol-Myers, and the ailment spikes their risk of stroke. Last year Pfizer and Bristol revealed that in a 18,201-patient study comparing Eliquis or apixaban to decades-old warfarin, the new clot buster lowered stroke risk by 21%, major bleeding by 31% and mortality by 11%.

"Blood clots in the heart can cause a disabling stroke if the clots travel to the brain," said Dr. Norman Stockbridge, director of the Division of Cardiovascular and Renal Products in the FDA's Center for Drug Evaluation and Research, in a statement.

Bristol and Pfizer have a potential mega-blockbuster product on their hands, with analysts estimating peak sales of more than $5 billion. The drug faces competition from similar drugs such as Xarelto from Johnson & Johnson ($JNJ) and Bayer and the bloodthinner Pradaxa from Boehringer Ingelheim. Yet some experts, including those cited by Leerink Swann, believe that Eliquis is the top new warfarin replacement.

Regulators in the European Union, Canada and Japan approved Eliquis before the FDA for the big AF market. The U.S. agency held up approval of the drug in June, requesting more information on data management and verification from the major Phase III study of more than 18,000 patients known as "Aristotle." Yet today's FDA approval comes almost three months before its March 17, 2013, PDUFA date.
