The Food and Drug Administration on Wednesday approved the first new drug to treat lupus in 56 years. It's not terribly effective: It only worked for 35% of the patients tested. But experts say the approval could prompt the development of more effective drugs.

The odds of shepherding a new drug to market in recent years has fallen to nearly one in 10 -- about half of the previous rate, according to a new study released this week.

Allergan's Lap-Band, a device implanted in the stomach to limit the amount of food that can be ingested, is already on the market to help the very obese lose weight. But now the company hopes to win approval for less obese patients to use the band.

The FDA has approved Amgen's osteoporosis drug denosumab for use by cancer patients with solid tumors whose disease has metastasized to their bones. The indication to prevent complications such as fractures and bone pain among those patients could boost the drug's sales by billions.
