A Study of Zipalertinib in Patients With Advanced Non-Small Cell Lung Cancer With Epidermal Growth Factor Receptor (EGFR) Exon 20 Insertions or Other Uncommon Mutation.

Inclusion Criteria: 1. Written informed consent. 2. ≥18 years of age (or meets the country's regulatory definition of legal adult age, whichever is greater. 3. Pathologically confirmed, locally advanced or metastatic NSCLC meeting all the following criteria: Cohort A participants: * Documented EGFR ex20ins status, as determined by local testing performed at a Clinical Laboratory Improvement Amendments (CLIA) certified (United States [US]) or locally certified laboratory (outside the US). * Progressed on or after systemic therapy with an agent targeting ex20ins, either alone or in combination with standard platinum-based chemotherapy for the treatment of advanced disease. Participants who discontinued previous treatment due to unacceptable toxicity are eligible. i. Permitted prior ex20ins therapies include: amivantamab, sunvozertinib (DZD9008), and BLU451. Other prior ex20ins–directed treatment may be discussed with the Sponsor for eligibility assessment. * Participants with brain metastasis must be neurologically stable. Participants must have received central nervous system (CNS)-directed therapy and have no evidence of progression for at least 4 weeks after CNS-directed treatment, as ascertained by clinical examination and brain imaging (magnetic resonance imaging [MRI] or computed tomography [CT] scan) during the Screening Period. Additionally, they must be on a stable or decreasing dose of corticosteroids and/or anti-convulsant medications for…
