Clinical summary

Summary

Eligible participants will be allocated to one of two cohorts based on their diagnosis and treatment history.

Cohort B1 will enrol people with primary non-small cell lung cancer that has been completely resected (removed with surgery). This cohort is a phase II cohort that will evaluate the safety and efficacy of alectinib in combination with up to four cycles of platinum-based chemotherapy in the adjuvant setting post complete surgical resection.

Cohort B2 will enrol people with non-small cell lung cancer that is able to be removed with surgery. It is a phase II cohort that will evaluate the efficacy and safety of perioperative alectinib in combination with chemotherapy in the neoadjuvant setting.

Conditions
