Nazartinib and Gefitinib in Treating Patients with Recurrent or Stage IIIB-IV EGFR-Mutant Non-small Cell Lung Cancer

Trial Status: Temporarily Closed to Accrual

This phase II trial studies how well nazartinib and gefitinib work in treating patients with EGFR-mutant non-small cell lung cancer that has come back or is stage IIIB-IV. Nazartinib and gefitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Inclusion Criteria

  • Participants must have a pathologically-confirmed diagnosis of non-small cell lung cancer (NSCLC)
  • Participants must have advanced disease - either stage IV disease, stage IIIB disease not amenable to definitive multi-modality therapy, or recurrent disease after a prior diagnosis of stage I-III disease; all staging is via the American Joint Committee on Cancer (AJCC)/International Association for the Study of Lung Cancer (IASLC) 7th edition proposed staging criteria
  • An EGFR sensitizing mutation must be detected in tumor tissue; specifically, patients harboring the most common mutations, deletions in exon 19 or the L858R mutation in exon 21 are eligible; other EGFR sensitizing mutations may be eligible after discussion with the principal investigator; patients may be enrolled in the study based on an activating EGFR mutation detected by a Clinical Laboratory Improvement Act (CLIA) certified tissue or plasma-based assay, but will be required to undergo a mandatory tumor biopsy during study screening
  • Participants must have measurable disease, per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
  • Patients in the six patient safety run-in cohort may have had a prior EGFR TKI in the metastatic setting (to allow for patients who started initial therapy at an outside hospital), but treatment duration must have been less than three months; after the initial six-patient safety run-in, no prior EGFR TKI therapy in the metastatic setting is allowed; an EGFR TKI given in the adjuvant setting (i.e. with no measurable disease at the time of administration) is allowable provided the subject has been off of EGFR TKI therapy for at least six months at the time of enrollment
  • Patients may have had no more than one prior line of chemotherapy or immunotherapy in the metastatic setting; at least 14 days must have elapsed from the last chemo/immunotherapy administration until the start of protocol treatment, and patients must have recovered from the side effects of any of these agents
  • Patients must be screened for hepatitis B virus (HBV); patients who are either hepatitis B surface antigen (HBsAg) positive or HBV-DNA positive must be willing and able to take antiviral therapy 1-2 weeks prior to 1st dose of study treatment and continue on antiviral therapy for at least 4 weeks after the last dose of EGF816; additional management of the patients would be provided by a physician with expertise in management of HBV, if needed; patients must have negative hepatitis C antibody (HCV-Ab) or positive HCV-Ab but undetectable level of HCV-ribonucleic acid (RNA); Note: patients with detectable HCV-RNA are not eligible for the study
  • Patients must receive insurance approval for or be willing to pay for commercial gefitinib
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
  • Life expectancy of greater than 12 weeks

  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional upper limit of normal; for patients with known hepatic metastases AST and/or ALT > 5 x ULN
  • Creatinine =< 1.5 x institutional upper limit of normal
  • The effects of EGF816 and gefitinib on the developing human fetus are unknown; for this reason, women of child-bearing potential and men must agree to use highly effective contraception during the study and for 3 months after stopping the study treatment; highly effective contraception methods include: * Total abstinence (when this is in line with the preferred and usual lifestyle of the subject; periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception * Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment * Male partner: male sterilization (at least 6 months prior to screening); for female subjects on the study the vasectomized male partner should be the sole partner for that subject * Combination of any two of the following (a+b or a+c, or b+c): ** A. Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception ** B. Placement of an intrauterine device (IUD) or intrauterine system (IUS) ** C. Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository ** D. In case of use of oral contraception women should have been stable on the same pill for a minimum of 30 days before taking study treatment * Women are considered post-menopausal and not of childbearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of childbearing potential * Sexually active males must agree to use a condom during intercourse while taking drug and for 3 months after stopping treatment; men should not father a child in this period; a condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid
  • Ability to understand and the willingness to sign a written informed consent document; written informed consent must be obtained prior to any screening procedures

Exclusion Criteria

  • Participants with clinically active or symptomatic interstitial lung disease or interstitial pneumonitis (i.e., affecting activities of daily living or requiring therapeutic intervention) and patients with history of clinically significant interstitial lung disease or radiation pneumonitis

PRIMARY OBJECTIVE:

I. To evaluate the efficacy of nazartinib (EGF816) in combination with gefitinib in the treatment of tyrosine-kinase inhibitor (TKI)-naive EGFR-mutant non-small cell lung cancer (NSCLC).

SECONDARY OBJECTIVES:

I. To describe the median progression free and overall survival of patients treated with EGF816 and gefitinib.

II. To evaluate the safety and tolerability of the EGF816/gefitinib combination.

EXPLORATORY OBJECTIVES:

I. To characterize the pharmacokinetic interactions between gefitinib and EGF816.

II. To evaluate resistance mechanisms to EGF816 and gefitinib.

III. To characterize the molecular response to treatment in on-treatment tumor biopsies and in circulating tumor deoxyribonucleic acid (DNA).

OUTLINE:

Patients receive gefitinib orally (PO) once daily (QD) and nazartinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days and every 3 months thereafter.
