Study details:

This study will evaluate the safety and efficacy of zipalertinib in patients with locally advanced or metastatic NSCLC harboring EGFR ex20ins mutations or other uncommon/single or compound EGFRmt. Patients will be enrolled into 1 of the 4 following cohorts:. * Cohort A ("prior ex20ins treatment") will include patients harboring EGFR ex20ins mutations who have progressed on or after initial treatment with standard platinum-based chemotherapy and prior treatment with an ex20 agent for their advanced disease (administered together or separately).

* Cohort B ("1st line") will include patients harboring EGFR ex20ins mutations who have not received prior treatment for advanced disease. * Cohort C ("active brain mets") will include patients harboring EGFR ex20ins or other uncommon single and compound mutations and active brain metastases. Patients may or may not have had prior treatment for advanced disease.

* Cohort D ("other uncommon EGFRmt") will include patients harboring other, non ex20ins uncommon single or compound EGFRmt who have progressed on or after treatment with standard systemic anticancer therapy.

Inclusion criteria

Written informed consent

≥18 years of age (or meets the country's regulatory definition of legal adult age, whichever is greater)

Pathologically confirmed, locally advanced or metastatic NSCLC meeting all the following criteria: Cohort A patients: Documented EGFR ex20ins mutation status, as determined by local testing performed at a CLIA certified (US) or locally certified laboratory (outside the US).

Patients who discontinued previous treatment due to unacceptable toxicity are eligible. Patients with brain metastasis must be neurologically stable. Patients must have received 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 (MRI or CT scan) during the screening period, and they must be on a stable or decreasing dose of corticosteroids and/or anti-convulsant medications for at least 2 weeks prior to the first dose of study treatment. Patients with history of uncontrolled seizures or leptomeningeal disease are not eligible. Cohort B patients: Documented EGFR ex20ins mutation status, as determined by local testing performed at a CLIA certified (US) or locally certified laboratory (outside the US).

Patients with brain metastasis must be neurologically stable. Patients must have received 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 (MRI or CT scan) during the screening period, and they must be on a stable or decreasing dose of corticosteroids and/or anti-convulsant medications for at least 2 weeks prior to the first dose of study treatment. Patients with history of uncontrolled seizures or leptomeningeal disease are not eligible.

Cohort D patients: Documented other non-ex20ins uncommon single or compound EGFRmt status, as determined by local testing performed at a CLIA certified (US) or locally certified laboratory (outside the US). A list of eligible mutations will be provided in a separate manual. Patients with brain metastasis must be neurologically stable. Patients must have received 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 (MRI or CT scan) during the screening period, and they must be on a stable or decreasing dose of corticosteroids and/or anti-convulsant medications for at least 2 weeks prior to the first dose of study treatment. Patients with history of uncontrolled seizures or leptomeningeal disease are not eligible.

Measurable disease per RECIST 1.1.

Archival tumor tissue available for submission, with minimum quantity sufficient to evaluate EGFRmt status and, where possible, other biomarkers (details provided in a laboratory manual). Patients with insufficient tissue may be eligible following discussion with the sponsor.

Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 or 17. Adequate organ function, as defined by the hematologic, renal and hepatic laboratory values.

Women of childbearing potential (WOCBP) must have a negative serum pregnancy test prior to administration of the first dose of study treatment. Female patients are not considered to be of childbearing potential if they are post-menopausal (no menses for 12 months without an alternative medical cause) or permanently sterile (hysterectomy, bilateral salpingectomy, or bilateral oophorectomy).

Both males and females of reproductive potential must agree to use effective birth control during the study prior to the first dose of study drug and for 6 months after the last dose of study treatment.

Exclusion criteria
