The data presentation will take place the International Association for the Study of Lung Cancer's Multidisciplinary Symposium in Thoracic Oncology on Friday in Chicago.

In other news, Array BioPharma Inc. (ARRY) said Thursday it had priced an underwritten public offering of  20.93 million shares at $10.75 apiece, which would generate gross proceeds of about $225 million before underwriting discounts and commissions and offering expenses.
