Inclusion Criteria

• •1. Willing and able to provide signed and dated informed consent prior to any study-related procedures and willing and able to comply with all study procedures
• •2. Age ≥ 18 years
• •3. ECOG ≤ 1
• •4. Patients with histologically or cytologically confirmed advanced/metastatic EGFR-mutant NSCLC
• •5. Patients must have measurable or evaluable disease per RECIST v1.1.
• •6. Patients must be willing to submit a blood sample for gene alteration analysis by next generation sequencing (NGS).
• •7. Archival tumor tissue (formalin-fixed paraffin-embedded) or a new biopsy is required prior to initiation of the study treatment for biomarker analysis.
• •8. Phase Ib a. Patients who have progressed on/after standard therapy and no other therapies are available Phase II
• •1. Total prior systemic therapy lines in the metastatic setting: ≤2 for Group 1, ≤3 for Group 2-3, ≤2 for Group 4.
• •2. Patients have progressed on/after a 3rd-generation EGFR TKI for Group 1-3; Patients have progressed on/after standard of care or other available treatment for Group 4. Note: For Group 4, a patient who has refused all currently available therapy is allowed to enroll, but this must be documented in the source record.
• •Group 1: Patient had a documented EGFR Exon 19del or L858R activating mutation and progressed while on osimertinib as first-line therapy in the advanced/metastatic setting.
• •Group 2: Patient has an EGFR T790M-persistent mutation, having progressed on/after 2nd- or later-line osimertinib or other 3rd-generation EGFR TKI.
• •Group 3: Patient had an EGFR T790M mutation, progressed on 2nd- or later-line osimertinib or another 3rd-generation EGFR TKI, and no longer harbors an EGFR T790M mutation.
• •Group 4: Patient has a documented EGFR Exon20ins activating mutation.
• •4. Patients with a history of clinically significant cardiovascular disease including:
• •* Diagnosis of deep vein thrombosis or pulmonary embolism within 4 weeks prior to the first dose of study treatment, or any of the following within 6 months prior to the first dose of study treatment: myocardial infraction, unstable angina, stroke, transient ischemic attack, coronary/peripheral artery bypass graft, or any acute coronary syndrome. Clinically non-significant thrombosis, such as non-obstructive catheter-associated clots, may be eligible.
• •* Mean resting ECG QT-interval corrected according to Fridericia's formula (QTcF) \> 470 milliseconds (ms) obtained from three ECGs, or clinically significant cardiac arrhythmia or electrophysiologic disease (e.g., placement of implantable cardioverter defibrillator or atrial fibrillation with uncontrolled rate). Patients with cardiac pacemakers who are clinically stable are eligible.
• •* Uncontrolled (persistent) hypertension: systolic blood pressure ≥150 mm Hg; diastolic blood pressure ≥90 mm Hg with or without anti-hypertensive medication
• •* Congestive heart failure (CHF)
• •* Pericarditis/clinically significant pericardial effusion
• •* Myocarditis
• •* Baseline left ventricular ejection fraction (LVEF) ejection fraction below the lower limit of normal (LLN), as assessed by screening echocardiogram or multigated acquisition (MUGA) scan
• •* Any patient with any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first-degree relatives
• •5. History of primary immunodeficiency, stem cell or organ transplant, or previous clinical diagnosis of tuberculosis
