The results are a blow to Gilead, which is working to become a power player in the cancer space.
Patients with advanced or metastatic non-small cell lung cancer who took Trodelvy lived longer than those who got chemotherapy alone, according to Gilead.
The drugmaker said it will discuss the results with regulators and identify whether certain lung cancer patients may still benefit from the drug.
Jefferies analyst Michael Yee said Gilead's trial results are not "totally surprising" to the firm because data from early studies was mixed and data for competing drugs was "lackluster."
Yee added that the trial results could "dent" investor confidence about whether Gilead will have significant sales in oncology.
