Informations complémentaires
Schéma : SCARCE is a non-comparative randomized, 2:1 phase II study. The purpose of this study is to assess the progression-free survival rate at 12 months. (evaluation according with RECISTv1.1 criteria).
For all patients, CT scan will be planned at baseline, and every 8 weeks until 12 months from randomization (or disease progression), and every 12 weeks thereafter.
PET scan will be performed at baseline, at the end of mDCF treatment, and at 12 months after randomization (in absence of disease progression).
CT scan and PET scan will be collected for a centralized review.

2 treatment arms:
- Experimental: ARM A - mDCF + Atezolizumab
MPDL3280A (atezolizumab) will be administered every 2 weeks at 800 mg for 12 months.
Patients will receive 8 cycles of mDCF (docetaxel 40 mg/m2 day 1, cisplatin 40 mg/m2 day 1 and 5FU at 1200 mg/m2/day for 2 days) every 2 weeks
- Active Comparator: ARM B - mDCF
Patients will receive 8 cycles of mDCF (docetaxel 40 mg/m2 day 1, cisplatin 40 mg/m2 day 1 and 5FU at 1200 mg/m2/day for 2 days) every 2 weeks.

Phase : II

Stade : Localement avancé à Métastatique
