Time frame
Following confirmed progression, patients were assessed every ~12 weeks until second disease progression. Assessed until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

What was measured

PFS2 was defined as the time from randomization to the time of the second progression or death. The date of second progression was recorded by the investigator and defined according to local standard clinical practice, and could have involved any of the following: objective radiological, symptomatic progression, or death. RECIST assessments were not collected for assessment of PFS2. PFS2 was calculated using the Kaplan-Meier technique.

Analysis population: FAS included all randomized patients, analyzed on an ITT basis.

Groups in this outcome

Durvalumab (MEDI4736)

Patients in the durvalumab (MEDI4736) monotherapy group were to receive durvalumab 10 mg/kg Q2W via intravenous infusion for up to 12 months.

Placebo

Patients in the placebo group were to receive matching placebo for intravenous infusion Q2W for up to 12 months.
