• Participants with AGA must meet the following criteria for advanced or metastatic NSCLC. Participants who have been treated with 1 or 2 prior lines of applicable targeted therapy that is locally approved (and is standard of care) for the participant's genomic alteration at the time of screening:
  • Participants who have tumors with EGFR L858R or exon 19 deletion mutations must have received prior osimertinib.
  • Participants who received a targeted agent as adjuvant therapy for early-stage disease must have relapsed or progressed while on the treatment or within 6 months of the last dose or received at least one additional course of targeted therapy for the same genomic alteration (which may or may not be same agent used in the adjuvant setting) for relapsed/progressive disease.

Postmenopausal is defined as 12 consecutive months with no menses without an alternative medical cause. Female participants of childbearing potential must have a negative serum pregnancy test at screening and adhere to using a highly effective method of contraception (eg, tubal ligation, approved hormonal contraceptive associated with inhibition of ovulation, or an intrauterine device \[IUD\]) prior to screening and agree to continue its use during the study or be surgically sterilized (eg, hysterectomy) while on study and for 7 months post last dose of study drug.

Participants MUST have received at least 1 targeted therapy or 2 or more if multiple lines of targeted therapies are approved in the region. Thus, participants must have exhausted regional Health Authority-approved targeted therapies for their specific AGA for first- or second-line NSCLC, then have acquired resistance to immune checkpoint therapy to be eligible. Participants must meet inclusion criteria #4.
• Participants with previously treated brain metastases may participate provided they are clinically stable for at least 2 weeks and have no evidence of new or enlarging brain metastases and also are off steroids 3 days prior to dosing with study medication. Stable brain metastases by this definition should be established prior to the first dose of study medication. Participants with asymptomatic brain metastases (ie, no neurological symptoms, no requirements for corticosteroids, and no lesion \>1.5 cm) may participate but will require regular imaging of the brain as a site of disease.
