Patient case: 50-year-old female with Lung cancer. Genetic variant: EGFR (L858R). Other conditions: Lupus.

Clinical trial: Afatinib and Necitumumab in Patients With EGFR Mutation Positive Advanced or Metastatic Non-small Cell Lung Cancer

Summary: 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.

Detailed description: 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.

  -  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)
  Exclusion Criteria:
  -  Prior treatment against NSCLC with an EGFR monoclonal antibody
