Clovis Oncology's (NASDAQ:CLVS) lung cancer drug CO-1686 was in the spotlight at ASCO today, and, while the drug seemed to be potentially more effective than AstraZeneca's (NYSE:AZN) competitor AZD9291, the stock still dropped.
In a phase 1/2 trial, CO-1686 caused high blood sugar in 22% of patients, according to Clovis, and CEO Pat Mahaffay reportedly commented that a few patients had to receive insulin injections to handle their hyperglycemia.
In this video, from Monday's Market Checkup, the Motley Fool's health care-focused investing show, analysts Michael Douglass and David Williamson discuss the side effects and what this could mean for Clovis moving forward.
Even if the next batch of data is much better, Clovis could have serious trouble keeping up with this top stock.
