Johnson & Johnson's (NYSE: JNJ ) drug Zytiga was just approved in a pre-chemotherapy indication for late-stage metastatic castration-resistant prostate cancer. This came as no surprise to investors; it received approval in Europe recently for a first-line therapy as well. In the following video, Motley Fool health-care analyst David Williamson talks about why this wasn't a big needle-mover for Johnson & Johnson share prices, but he also tells us that it was a critical step forward not only for J&J, which wants to see Zytiga hit the $1 billion mark, but also for Dendreon (NASDAQ: DNDN ) , which is working on some tandem treatment trials with Zytiga and its pre-chemo immunotherapy drug Provenge, that could prove to be huge share price drivers if successful.
Dendreon's run over the past four years had sub-$5 share prices skyrocketing to 10-bagger status before tumbling all the way back down below $5, as its revolutionary prostate cancer vaccine Provenge became a lightning rod of debate. But where does that leave investors -- other than a bit nauseated from the roller-coaster ride? Our own David Williamson answers this question, and many more, inside our brand-new premium research report on Dendreon. Inside, he details every key issue facing the company and outlines just how Dendreon intends to regain its former glory.
