Study Arms (2)
Cohort 1: osimertinib, 80mg, daily, P.O.
ACTIVE COMPARATORPatients 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receive study medication in 28 day cycles until objective disease progression, unacceptable toxicity occurs, consent is withdrawn or another discontinuation criterion is met.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.
Cohort 2: osimertinib 80mg daily, P.O. and savolitinib 300mg BID, P.O.
EXPERIMENTALAll 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 Treatment will continue until either objective disease progression, unacceptable toxicity occurs, consent is withdrawn or another discontinuation criterion is met.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.

- +21 more criteria
You may not qualify if:
- Participants are excluded from the study if any of the following criteria apply:

- Mean resting correct QT interval (QTcF) \>470 msec for women and \>450 msec for men at Screening, obtained from 3 ECGs using the screening clinic ECG machine derived QTcF value.
- Any factors that may increase the risk of QTcF prolongation or risk of arrhythmic events such as heart failure, electrolyte abnormalities (including: Serum/plasma potassium \< LLN; Serum/plasma magnesium \< LLN; Serum/plasma calcium \< LLN), congenital or familial long QT syndrome, family history of unexplained sudden death under 40 years of age in first-degree relatives or any concomitant medication known to prolong the QT interval and cause Torsade de Pointes.
- Any clinically important abnormalities in rhythm, conduction or morphology of resting ECGs, eg, complete left bundle branch block, third degree heart block, second degree heart block, P-R interval \>250 msec.
- Acute coronary syndrome
- Wide field radiotherapy (including therapeutic radioisotopes such as strontium 89) administered ≤28 days or limited field radiation for palliation ≤7 days prior to starting study drug or has not recovered from side effects of such therapy.
