Haystack 2010 Year-In-Review

This Friday, we're looking back at 2010's big news in pharma and biotech, both the good and the bad. Check out our picks and be sure to weigh in on what you think we missed. 1. Provenge Approved In April, Dendreon's Provenge became the first approved cancer immunotherapy. Dendreon CEO Mitch Gold called it “the dawn of an entirely new era in medicine.” And while prostate cancer patients are excited for a new treatment option, the approval is perhaps most exciting for its potential to reignite interest in cancer immunotherapy research. There’s a lot of room for improving the approach—Provenge is, after all, expensive and highly individualized. Now that immunotherapy have been proven to work, there’s hope that the lessons learned in both its discovery and clinical development will aid scientists in inventing even better cancer vaccines. 2. Obesity Field Slims The obesity drug race played out in dramatic fashion in 2010, with three biotech companies-Vivus, Arena, and Orexigen, each making their case for its weight-loss medication before FDA. As of this writing, Orexigen's drug Contrave seems to be on the surest footing to approval, but longtime obesity-drug watchers know that caution seems to rule the day at FDA, so nothing is a sure bet. Orexigen's Contrave and Vivus's Qnexa are both combinations of already-approved drugs, whereas Arena's Lorqess is a completely new molecule. When C&EN covered the obesity race in 2009, it seemed that Lorqess (then going by the non-brand-name lorcaserin) had the cleanest safety profile, but Qnexa was best at helping patients lose weight. But FDA's panels didn't always play out the way folks expected. There were safety surprises- notably the worries about tumors that cropped up in rats on high doses of Lorqess, and the extensive questioning about birth defect risks from one of the ingredients in Vivus' Qnexa. The fact that FDA's panel voted favorably for Orexigen's Contrave, a drug that's thought to have some cardiovascular risks, generated discussion because FDA pulled Abbott's Meridia, a diet drug with cardiovascular risks, from the market in October. The dust still hasn't fully settled. Arena and Vivus received Complete Response Letters from FDA for Lorqess and Qnexa. Vivus has submitted additional documentation and a followup FDA meeting on Qnexa is happening in January. Also to come in January is the agency's formal decision on Contrave.

Sanofi & Genzyme: The Neverending Story Speaking of drama, Sanofi’s pursuit of Genzyme has been in the headlines for months now, and promises to stretch well into 2011. The...
