The Wall Street Journal recently reported that Bristol-Myers Squibb stock dropped dramatically on August 5th, 2016. This occurred after clinical trial results indicated that BMS’s immunotherapy drug OPDIVO® (nivolumab) failed to demonstrate a clinical improvement compared to chemotherapy in patients with newly-diagnosed lung cancer.

The impact of this announcement shows that the stakes are higher than just obtaining regulatory approval. Clinical trial results can have immediate and significant consequences before any regulatory decisions are even made. Here we discuss the importance of comparative efficacy research on market access, pricing, profitability, and competition.
