  • OS

    18 months after the last patient enrolled

  • +1 more secondary outcomes

Study Arms (2)

Cohort 1: osimertinib, 80mg, daily, P.O.

ACTIVE COMPARATOR

Patients will continue to receive study medication in 28 day cycles until objective disease progression, unacceptable toxicity occurs, consent is withdrawn or another discontinuation criterion is met. Patients who progress on first-line treatment of osimertinib monotherapy will have the opportunity to receive second-line treatment of osimertinib plus savolitinib after confirmation of MET status at disease progression.

Drug: Osimertinib

Cohort 2: osimertinib 80mg daily, P.O. and savolitinib 300mg BID, P.O.

EXPERIMENTAL

All eligible patients will be randomized to receive treatment with osimertinib (80 mg daily) or osimertinib (80 mg daily) in combination with savolitinib (300 mg BID) in this study. Treatment will continue until either objective disease progression, unacceptable toxicity occurs, consent is withdrawn or another discontinuation criterion is met. Patients in Cohort 2 can continue on savolitinib monotherapy (if osimertinib was stopped earlier) or osimertinib monotherapy (if savolitinib was stopped earlier) until objective disease progression or meet any of the discontinuation criteria.

Drug: OsimertinibDrug: Savolitinib
