Participants with chronic Grade 2 toxicities may be eligible at the discretion of the Investigator after consultation with the Sponsor Medical Monitor or designee.

• Participant with any human immunodeficiency virus (HIV) infection.

Laborértékek

• Inadequate washout period prior to Cycle 1 Day 1, defined as:
  • Whole brain radiation therapy <14 days or stereotactic brain radiation therapy <7 days;
  • Any cytotoxic chemotherapy, investigational agent or other anticancer drug(s) from a previous cancer treatment regimen or clinical study (other than EGFR TKI), <14 days or 5 half-lives, whichever is longer;
  • Monoclonal antibodies, other than immune checkpoint inhibitors, such as bevacizumab (anti-VEGF) and cetuximab (anti-EGFR) <28 days;
  • Immune checkpoint inhibitor therapy <21 days;
  • Major surgery (excluding placement of vascular access) <28 days;
  • Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation <28 days or palliative radiation therapy <14 days; or
  • Chloroquine or hydroxychloroquine <14 days.

Egyéb

• Participants meeting any exclusion criteria for this study will be excluded from this study.
• Evidence of clinically active spinal cord compression or brain metastases.

• Participants must meet all of the following criteria to be eligible for inclusion in this study.
• Sign and date the tissue informed consent form (ICF) and the main ICF, prior to the start of any study-specific qualification procedures.
• Male or female participants aged ≥18 years (follow local regulatory requirements if the legal age of consent for study participation is >18 years old).
• Histologically or cytologically documented locally advanced or metastatic NSCLC not amenable to curative surgery or radiation.
• Documentation of radiological disease progression while on/after receiving most recent treatment regimen for locally advanced or metastatic disease. Participants must have received both of the following:
  • Prior treatment with osimertinib. Participants receiving an EGFR TKI at the time of signing informed consent should continue to take the EGFR TKI until 5 days prior to Cycle 1 Day 1. Participants in South Korea known to harbor a clinically actionable genomic alteration in addition to EGFR mutation (e.g., anaplastic lymphoma kinase [ALK] or ROS1 protocol oncogene 1 [ROS1] fusion) for which treatment is available must have also received prior treatment with at least 1 approved genotype-directed therapy, unless unable (i.e., if contraindicated). No new testing for these genomic alterations (e.g., ALK or ROS1 fusion) is required for Screening.
  • Systemic therapy with at least 1 platinum-based chemotherapy regimen.
• Documentation of an EGFR-activating mutation detected from tumor tissue or blood sample: exon 19 deletion or L858R.
• At least 1 measurable lesion confirmed by BICR as per RECIST v1.1
• Consented and willing to provide required tumor tissue of sufficient quantity and of adequate tumor tissue content. Required tumor tissue can be provided as either:
  • Pretreatment tumor biopsy from at least 1 lesion not previously irradiated and amenable to core biopsy OR
  • Archival tumor tissue collected from a biopsy performed within 3 months prior to signing of the tissue consent and since progression while on or after treatment with the most recent cancer therapy regimen.
• Eastern Cooperative Oncology Group Performance Standard of 0 or 1 at Screening.
• Has adequate bone marrow reserve and organ function based on local laboratory data within 14 days prior to Cycle 1 Day 1:
  • Platelet count : ≥100,000/mm\^3 or ≥100 × 10\^9/L (platelet transfusions are not allowed up to 14 days prior to Cycle 1 Day 1 to meet eligibility)
  • Hemoglobin: ≥9.0 g/dL (transfusion and/or growth factor support is allowed)
  • Absolute neutrophil count: ≥1500/mm\^3 or ≥1.5 × 10\^9/L
  • Serum creatinine (SCr) or creatinine clearance (CrCl): SCr ≤1.5 × upper limit of normal (ULN), OR CrCl ≥30 mL/min as calculated using the Cockcroft-Gault equation or measured CrCl
  • Aspartate aminotransferase/alanine aminotransferase: ≤3 × ULN (if liver metastases are present, ≤5 × ULN)
  • Total bilirubin: ≤1.5 × ULN if no liver metastases (<3 × ULN in the presence of documented Gilbert's syndrome [unconjugated hyperbilirubinemia] or liver metastases)
  • Serum albumin: ≥2.5 g/dL
  • Prothrombin time (PT) or PT-International normalized ratio (INR) and activated partial thromboplastin time (aPTT)/PTT: ≤1.5 × ULN, except for subjects on coumarin-derivative anticoagulants or other similar anticoagulant therapy, who must have PT-INR within therapeutic range as deemed appropriate by the Investigator
