			 Two of the new injectable cholesterol treatments, called PCSK9 
			inhibitors, could gain U.S. approval this summer. CVS said they 
			could eventually be used by as many as 15 million patients at an 
			annual cost of up to $150 billion a year if priced at $7,000 to 
			$12,000 a year, making it the highest-selling class of drugs in 
			history. 
			 
			"The resilience and ability of our health care system to absorb such 
			high costs will be tested if rigid cost control mechanisms are not 
			put in place," William Shrank, chief scientific officer for CVS, 
			said in a statement. 
			 
			CVS, the second-largest U.S. pharmacy benefit manager (PBM), 
			negotiates drug prices for 65 million people through contracts with 
			employers and health plans. 
			 
			The CVS call for cost controls follows sharp criticism from 
			insurers, other payers and politicians over the high cost of new, 
			highly effective treatments for hepatitis C, especially two 
			medicines from Gilead Science Inc that have retail prices of up to 
			$94,500 per patient for a course of treatment. 
			
			  
			Unlike those drugs, which are typically taken for about 12 weeks, 
			the PCSK9s would be used for a lifetime. 
			 
			Express Scripts, the largest U.S. PBM, which has waged a campaign 
			against Gilead's hepatitis C drugs and is now scrutinizing costly 
			cancer medications, provided a slightly different view of the new 
			cholesterol drug market. 
			 
			Express Scripts also expects annual costs of around $10,000 per year 
			per patient. But it sees a patient population that will start small 
			before it ever reaches a possible high of 10 million people and a 
			potential annual cost of $100 billion. 
			 
			Express Scripts Chief Medical Officer Steve Miller said in an 
			interview that limits set by regulators and the fact that the first 
			wave of drugs are injections may slow their uptake.

			"We are going to work to get these products at the best price 
			possible, but they also deserve to get value in the marketplace," 
			Miller said. 
			 
			Amgen Inc and a partnership of Sanofi and Regeneron Pharmaceuticals 
			Inc are awaiting approval of rival PCSK9 inhibitors. 
			 
			They are expected to be used first by patients who are genetically 
			prone to extreme high cholesterol - a population that CVS and 
			Express peg at 620,000 Americans. They also are likely to be used by 
			those who cannot tolerate standard statin treatments, like Pfizer 
			Inc's Lipitor. 
			 
			Amgen declined to comment on the pricing issue and Regeneron did not 
			respond to a request for comment. 
			 
			Shares of Amgen closed up 0.5 percent at $154.24, while Regeneron's 
			stock gained 0.4 percent to $404.18. Sanofi's shares slipped 0.2 
			percent to 85.53 euros in trading in Paris.
