What was measured

DOR was defined for participants who had an objective response as the time from the first occurrence of a documented unconfirmed response (CR or PR) to the date of disease progression per RECIST v1.1 or death from any cause, whichever occurred first.

Analysis population: The duration of response (DOR)-evaluable population is defined as patients with an objective response.

Groups in this outcome

Placebo Plus Nab-Paclitaxel

Participants assigned to placebo plus nab-paclitaxel received both agents until disease progression or unacceptable toxicity.

Atezolizumab Plus Nab-Paclitaxel

Participants assigned to atezolizumab plus nab-paclitaxel received both agents until disease progression or unacceptable toxicity.
