Both firms tested drugs that harness a patient's immune system to fight cancer. Their regimens were studied in patients with a common form of advanced lung cancer. These patients had never been treated, and their cancer had spread.

A regimen of Bristol's immuno-oncology drugs Opdivo and Yervoy cut the risk of cancer progression or death by 42% compared with chemotherapy. Merck's regimen, however, used a combination of Keytruda with chemotherapy, which reduced the risk of death by 51%.

On the stock market today, Bristol tanked 7.8% to close at 54.08. Merck, on the other hand, lifted 2.6% to 58.65. Both companies unveiled their results during the American Association for Cancer Research annual meeting in Chicago.
