Brief summary
This randomized, active-controlled, multicenter, open-label, Phase III study is designed to investigate the efficacy and safety of alectinib compared with platinum-based in the adjuvant setting. Participants in the experimental arm will receive alectinib at 600 mg orally twice daily (BID) taken with food for 24 months. Participants in the control arm will receive one of the protocol specified platinum based chemotherapy regimens for 4 cycles. Following treatment completion, participants will be followed up for their disease until disease recurrence. At the time of disease recurrence, participants will enter a survival follow-up until death, withdrawal of consent or study closure, whichever occurs earlier.
Interventions
Participants will receive alectinib 600 mg orally BID until completion of treatment period (24 months) or recurrence of disease , unacceptable toxicity, withdrawal of consent or death, whichever occurs first.
Participants will receive Cisplatin 75 milligrams per square meter (mg/m\^2) on Day 1 every 21 days IV intravenously (IV) until completion of treatment period (4 cycles), recurrence of disease, unacceptable toxicity, withdrawal of consent, or death, whichever occurs first."
Participants will receive Vinorelbine 25 mg/m\^2 IV on Days 1 and 8 Q21D until completion of treatment period (4 cycles), recurrence of disease, unacceptable toxicity, withdrawal of consent, or death, whichever occurs first.
Participants will receive Gemcitabine 1250 mg/m\^2 on Days 1 and 8 Q21D IV until completion of treatment period (4 cycles), recurrence of disease, unacceptable toxicity, withdrawal of consent, or death, whichever occurs first.
Participants will receive 500 mg/m\^2 Day 1 Q21D until completion of treatment period (4 cycles), recurrence of disease, unacceptable toxicity, withdrawal of consent, or death, whichever occurs first."
For participants who experience unacceptable toxicity with cisplatin, carboplatin can be used.
