Low accrual

This phase I trial studies the side effects and best dose of afatinib and necitumumab and to see how well they work in treating patients with EGFR mutation positive non-small cell lung cancer that has spread to other places in the body. Afatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as necitumumab, may interfere with the ability of tumor cells to grow and spread. Giving afatinib and necitumumab may work better in treating patients with EGFR mutation positive non-small cell lung cancer.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose of combination afatinib and necitumumab therapy in EGFR mutation positive non-small cell lung cancer (NSCLC) patients who have progressed following first- and third-generation EGFR tyrosine kinase inhibitors (TKIs).

II. To determine the efficacy and safety profile of afatinib and necitumumab combination therapy in patients with EGFR mutation positive NSCLC patients who have progressed following first- and third-generation EGFR TKIs.

OUTLINE: This is a dose-escalation study.

Patients receive afatinib orally (PO) once daily (QD) on days 1-28 and necitumumab intravenously (IV) over 60 minutes on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 28 days and then every 3 months for up to 1 year.

Inclusion Criteria:

• Signed and dated written informed consent

• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2

• Histologically or cytologically-confirmed advanced or metastatic non-small cell lung cancer (NSCLC) that is EGFR mutation positive; rare sensitizing mutations allowed

• Progression on a first generation EGFR TKI (T790M negative), or progression on a third generation TKI (if T790M positive at time of progression on a first or second generation TKI)

• At least one measurable lesion as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 that can be followed by computed tomography (CT) or magnetic resonance imaging (MRI)

• Patient consents to undergo a medically safe tumor biopsy at time of disease progression for mutation analysis

• Leukocytes >= 3,000/uL

• Absolute neutrophil count (ANC) >= 1,500/uL

• Platelets >= 100,000/uL

• Calculated creatinine clearance > 50 mL/min (per the Cockcroft-Gault formula)

• Total bilirubin =< 1.5 times upper limit of normal (ULN)

• Alkaline phosphatase (ALP) =< 3.0 x ULN

• Alanine aminotransferase (ALT) and aspartate transaminase (AST) =< 3.0 x ULN; for patients with hepatic metastases, ALT and AST =< 5.0 x ULN are acceptable

  * Note: if a patient experiences elevated ALT > 5 x ULN and elevated total bilirubin > 2 x ULN, clinical and laboratory monitoring should be initiated by the investigator; for patients entering the study with ALT > 3 x ULN, monitoring should be triggered at ALT > 2 x baseline

• Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within 14 days prior to receiving first dose of study medication; and additionally agree to use at least two methods of birth control or abstain from heterosexual intercourse from the time of signing consent, and until 6 months after patient's last dose of study drug

  * WOCBP of childbearing potential are defined as those not surgically sterile or not post-menopausal (i.e. if a female patient has not had a bilateral tubal ligation, a bilateral oophorectomy, or a complete hysterectomy; or has not been amenorrheic for 24 months in the absence of an alternative medical cause, then patient will be considered a female of childbearing potential); postmenopausal status in females under 55 years of age should be confirmed with a serum follicle-stimulating hormone (FSH) level within laboratory reference range for postmenopausal women

• WOCBP must agree to follow instructions for method(s) of contraception from the time of signing consent and until 6 months after last dose of study therapy

• Men able to father children who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception from the time of signing consent and until 6 months after last dose of study therapy; men able to father children are defined as those who are not surgically sterile (i.e. patient has not had a vasectomy)

• History of arterial or venous thromboembolism within 3 months prior to study enrollment; patients with a history of venous thromboembolism beyond 3 months prior to study enrollment can be enrolled if they are appropriately treated with low molecular weight heparin
• Subjects with a history of interstitial lung disease (e.g., sarcoidosis) that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity; subjects with chronic obstructive pulmonary disease (COPD) whose disease is controlled at study entry are allowed
• Symptomatic brain metastases; stable and treated central nervous system (CNS) disease allowed; patients with treated, asymptomatic brain metastases are eligible if there has been no change in brain disease status for at least two (2) weeks prior to initiating study treatment; anticonvulsant therapy will be allowed if patient is on a stable or decreasing dose of anticonvulsant treatment for at least two (2) weeks prior to initiating study treatment
• Subjects with carcinomatous meningitis
• Prior radiotherapy or radiosurgery < 2 weeks prior to starting study treatment
• Current symptomatic congestive heart failure (New York Heart Association classification >= grade III), unstable cardiac arrhythmia requiring therapy (e.g. medication or pacemaker), unstable angina (e.g. new, worsening or persistent chest discomfort), or uncontrolled hypertension (systolic > 160 mmHg or diastolic > 100 mmHg); or any of the following occurring within 6 months (180 days) prior to first dose of study treatment: myocardial infarction, coronary/peripheral artery bypass graft, cerebrovascular accident or transient ischemic attack; use of antihypertensive medication to control blood pressure is allowed
