Drug makers are enjoying a research-and-development revival after a fallow period. Last year the U.S. Food and Drug Administration approved 45 new drugs, more than double the number in 2006. But the industry also faces growing criticism of the prices it charges for new drugs—some cancer therapies cost as much as $150,000 a year—as well as repeated price increases for older drugs. Critics say high prices are putting drugs out of reach for many patients and straining health-care budgets. (Loftus, 2/21)

If a strategy works in the pharmaceutical industry, then you can bet someone will take it to its furthest extreme. Alexion has been a pioneer in two hot industry trends: marketing rare-disease, or "orphan," drugs and jacking up prices. It sells its drug Soliris, which treats rare blood disorders, for as much as $525,000 a year. Its newest drug Kanuma, which treats a rare genetic enzyme deficiency, could cost even more per patient per year, according to the U.K.'s health-care cost watchdog, known as NICE. (Nisen, 2/19)

Before he died early last year of pancreatic cancer, Stephen T. Johnson filed a lawsuit against Merck for not telling him his disease might be a side effect of taking Januvia, the company's blockbuster diabetes drug. The 63-year-old Philadelphia police officer knew his life was at an end, but he wanted the product labeling changed to warn other diabetics. (McCullough, 2/19)

Oscar Health Insurance Corp. CEO Mario Schlosser has found the strategy he says will build his startup into a million-customer player in the health insurance industry: use tight, exclusive networks with hospitals to sell competitively priced insurance in perhaps 30 U.S. markets. (Tracer, 2/19)
