Inclusion criteria

Inclusion criteria: - Participant must have at least 1 measurable lesion, according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, that has not been previously irradiated - Participant must have histologically or cytologically confirmed, locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC), characterized at or after the timne of locally advanced or metastatic disease diagnosis by either epidermal growth factor receptor (EGFR) Exon 19del or Exon 21 L858R mutation - A participant with a history of brain metastases must have had all lesions treated as clinically indicated (that is, no current indication for further definitive local therapy). Any definitive local therapy to brain metastases must have been completed at least 14 days prior to randomization and the participant can be receiving no greater than10 milligrams (mg) prednisone or equivalent daily for the treatment of intracranial disease - Participant must have Eastern Cooperative Oncology Group (ECOG) status of 0 or 1 - Any toxicities from prior systemic anticancer therapy must have resolved to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0 Grade 1 or baseline level (except for alopecia [any grade], Grade <= 2 peripheral neuropathy, or Grade <= 2 hypothyroidism stable on hormone replacement) - A woman of childbearing potential must have a negative serum pregnancy test at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study - Participant must have progressed on or after osimertinib monotherapy as the most recent line of treatment. Osimertinib must have been administered as either the first-line treatment for locally advanced or metastatic disease or in the second- line setting after prior treatment with first- or second-generation EGFR tyrosine kinase inhibitor (TKI) as a monotherapy. Participants who received either neoadjuvant and/or adjuvant treatment of any type are eligible if progression to locally advanced or metastatic disease occurred at least 12 months after the last dose of such therapy and then the participant progressed on or after osimertinib in the locally advanced or metastatic setting. Treatment with osimertinib must be discontinued at least 8 days (4 half-lives) prior to randomization (that is last dose no later than Day -8)

Exclusion criteria

Exclusion criteria: - Participant received radiotherapy for palliative treatment of NSCLC less than 14 days prior to randomization - Participant with symptomatic or progressive brain metastases - Participant has history of or current evidence of leptomeningeal disease, or participant has spinal cord compression not definitively treated with surgery or radiation - Participant has known small cell transformation - Participant has a medical history of interstitial lung disease (ILD), including drug-induced ILD or radiation pneumonitis - Participant has a history of clinically significant cardiovascular disease including, but not limited to diagnosis of deep vein thrombosis or pulmonary embolism within 4 weeks prior to randomization; myocardial infarction; unstable angina; stroke; transient ischemic attack; coronary/peripheral artery bypass graft; or acute coronary syndrome. Participant has a significant genetic predisposition to venous thromboembolic events. Participant has a prior history of venous thromboembolic events and is not on appropriate therapeutic anticoagulation as per National Comprehensive Cancer Network or local guidelines

Design outcomes

Primary

MeasureTime frame
Progression-Free Survival (PFS) According to RECIST v1.1 Guidelines as Assessed by Blinded Independent Central Review (BICR) PFS is defined as the time from randomization until the date of objective disease progression or death, whichever comes first, using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

Secondary

MeasureTime frame
Objective Response as Assessed by BICR Objective response is defined as the percentage of participants who achieve either a complete response (CR) or partial response (PR) as their best response as defined by BICR using RECIST v1.1 criteria. Overall Survival (OS) Overall Survival is defined as the time from the date of randomization to the date of participant's death due to any cause. Duration of Response (DoR) DoR is defined as the time from the date of first documented response (CR or PR) until the date of documented progression or death, whichever comes first, only for participants who achieve CR or PR. Time to Subsequent Therapy (TTST) TTST is defined as the time from the date of randomization to the start date of the subsequent anti-cancer therapy following study treatment discontinuation, or death whichever comes first. Progression-Free Survival After First Subsequent Therapy (PFS2) PFS2 is defined as the time from randomization until the date of second objective disease progression, after initiation of subsequent anticancer therapy, based on investigator assessment (after that used for PFS) or death, whichever comes first. Time to Symptomatic Progression (TTSP) TTSP is defined as the time from randomization to documentation in the electronic case report form (eCRF) of any of the following (whichever occurs earlier): onset of new symptoms or symptom worsening that is considered by the investigator to be related to lung cancer and requires either a change in anticancer treatment and/or clinical intervention to manage symptoms. Intracranial PFS Intracranial PFS is defined as the time from randomization until the date of objective intracranial disease progression or death, whichever comes first, based on BICR using RECIST v1.1. Number of Participants with Adverse Events (AEs) An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological ag
