Time frame
Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~ 12 weeks thereafter until confirmed disease progression. Assessed until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

What was measured

TTDM was defined as the time from the date of randomization until the first date of distant metastasis or death in the absence of distant metastasis. Distant metastasis was defined as any new lesion that was outside of the radiation field according to RECIST 1.1 or proven by biopsy. TTDM 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.
