简要总结
This randomized phase II/III trial studies how well afatinib dimaleate with cetuximab works and compares it with afatinib dimaleate alone in treating patients with newly diagnosed stage IV or recurrent (has come back), epidermal growth factor receptor (EGFR) mutation positive non-small cell lung cancer. Afatinib dimaleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, may block tumor growth in different ways by targeting certain cells. It is not yet known whether afatinib dimaleate is more effective when given alone or with cetuximab in treating patients with non-small cell lung cancer.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate if there is sufficient evidence to continue to the phase III component by comparing progression-free survival (PFS) between patients randomized to afatinib (afatinib dimaleate) in combination with cetuximab versus afatinib alone in the first-line treatment of patients with advanced EGFR-mutant non-small cell lung cancer (NSCLC). (Phase II) II. To determine the efficacy of the combination of afatinib and cetuximab compared to afatinib alone as measured by overall survival (OS) in the first-line treatment of patients with advanced EGFR-mutant NSCLC. (Phase III)
SECONDARY OBJECTIVES:
I. To evaluate the overall response rate (confirmed and unconfirmed, complete and partial responses) in the subset of patients with measurable disease treated with afatinib plus cetuximab compared to afatinib alone.
II. To assess the safety of each treatment arm when used in the first-line setting.

- •Patients may have measurable or non-measurable disease documented by computed tomography (CT) or magnetic resonance imaging (MRI) within 42 days prior to registration; the CT from a combined positron emission tomography (PET)/CT may be used only if it is of diagnostic quality; laboratory parameters are not acceptable as the only evidence of disease; in order to qualify as measurable, measurable disease must be outside previous radiation field; all disease must be assessed and documented on the Baseline Tumor Assessment Form (Response Evaluation Criteria in Solid Tumors [RECIST] 1.1)
- •Patients must have a CT or MRI scan of the brain to evaluate for central nervous system (CNS) disease within 42 days prior to registration; patient must not have symptomatic brain metastases or evidence of leptomeningeal carcinomatosis; patients with asymptomatic brain metastases are eligible if off of steroids for at least 7 days prior to registration without development of symptoms
- •Patients must not have any known clinically active interstitial lung disease
- •Absolute neutrophil count (ANC) >= 1,500/mcL
- •Platelets >= 75,000/mcL
- •Hemoglobin >= 9 g/dL
- •Total bilirubin =< 1.5 x institutional upper limit of normal (IULN)
- •Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x IULN (or =< 5 x IULN for patients with known liver metastases)
- •Serum creatinine =< 1.5 x IULN OR measured or calculated creatinine clearance >= 60 mL/min
- •Patients must not have significant gastrointestinal disorders with diarrhea as a major symptom (e.g. Crohn's disease, malabsorption, etc)
- •Patients must be able to swallow medication by oral route
- •Patients must not have a history of clinically relevant cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure New York Heart Association (NYHA) classification of 3, unstable angina or poorly controlled arrhythmia or myocardial infarction within 6 months prior to registration; if clinically indicated, echocardiogram or multigated acquisition (MUGA) must be performed and cardiac ejection fraction must be >= 50%
- •Patients must not have had major surgery within 28 days prior to registration or be scheduled for surgery during the projected course of protocol treatment; tumor biopsy is allowed
- •Patients must not have a known history of active hepatitis B infection (defined as presence of hepatitis B surface antigen [Hep B sAg] and/ or Hep B deoxyribonucleic acid [DNA]), active hepatitis C infection (defined as presence of hepatitis C [Hep C] ribonucleic acid [RNA]) and/or known human immunodeficiency virus (HIV) seropositive
- •Patients must not have any other concomitant serious illness or organ system dysfunction which in the opinion of the investigator would either compromise patient safety or interfere with the evaluation of the safety of the study drug
- •Patients must not be planning to receive any other investigational agents during the course of protocol treatment
- •Patients must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to afatinib and/or cetuximab
- •Prestudy history and physical must be obtained with 28 days prior to registration
- •Patients must have Zubrod performance status of 0 - 2
- •No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for three years
- •Patients must not be pregnant or nursing; women/men of reproductive potential must have agreed to use an effective contraceptive method; a woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months; in addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation; however, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures
