About
This phase I trial is studying the side effects and best dose of erlotinib hydrochloride when given together with cetuximab and to see how well they work in treating patients with advanced gastrointestinal cancer, head and neck cancer, non-small cell lung cancer, or colorectal cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Erlotinib hydrochloride and cetuximab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving erlotinib hydrochloride together with cetuximab may kill more tumor cells.
Full description
PRIMARY OBJECTIVES:
I. To identify the maximum tolerated dose (MTD). II. To identify the recommended dose (RD) for phase II of erlotinib (erlotinib hydrochloride) in combination with cetuximab in patients (pts) with incurable gastrointestinal, head and neck, or non-small cell lung cancers that are Kirsten rat sarcoma viral oncogene homolog (KRAS) wild type.
SECONDARY OBJECTIVES:
I. To identify dose-limiting toxicities (DLT). II. To perform skin and tumor biopsies to analyze molecular inhibition of the epidermal growth factor receptor (EGFR) signaling pathway, defined as a >= 75% inhibition of phosphorylation of the epidermal growth factor (EGF) receptor or of its downstream effectors tumor protein (p)44/42 mitogen-activated protein kinase (MAPK) or protein kinase B (Akt) or as a >= 25% decrease of marker of proliferation Ki-67 (Ki67) from baseline in either skin or tumor tissue in the majority of patients.
III. To identify the optimal biological dose (OBD). IV. To describe any antitumor effect observed.
OUTLINE: This is a phase I, dose-escalation study of erlotinib hydrochloride.
Patients receive cetuximab intravenously (IV) over 1-2 hours on days 1, 8, and 15 and erlotinib hydrochloride orally (PO) once daily (QD) on days 8-21. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for 4 weeks.

Inclusion criteria
- Patients must have histologically or cytologically confirmed incurable gastrointestinal tract, head and neck, or non-small cell lung cancers that are KRAS wild type; if KRAS mutational status cannot be determined on archived tumor tissue from the patient, a needle or excisional biopsy of a malignant site may be performed prior to enrollment; mutational status may be determined either by polymerase chain reaction (PCR) assay (e.g., DxS KRAS mutation kit) or by direct sequencing of KRAS exon 2, codons 12 and 13; the result must detect no mutations at these sites
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
- Leukocytes >= 3,000/mcL
- Absolute neutrophil count >= 1,500/mcL
- Platelets >= 100,000/mcL
- Total bilirubin within normal institutional limits
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X institutional upper limit of normal
- Creatinine within normal institutional limits or creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
- Eligibility of patients receiving any medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of erlotinib will be determined following review of their case by the principal investigator; although concomitant use of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducers is not prohibited in this study, identification of MTD and DLT may be affected by their use; concomitant use of any of these drugs will be noted in the case report forms and will be taken into account in determining MTD and DLT of this therapy; efforts should be made to switch patients with a history of brain metastases who are taking enzyme-inducing anticonvulsant agents to other medications
- Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
- Other prior malignancies are allowed provided prior therapy has been discontinued and there is no evidence of disease (NED)
- Patients must be able to take and retain oral medications
- Ability to understand and the willingness to sign a written informed consent document
Exclusion criteria
- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
- Patients may not be receiving any other investigational agents
- Patients with a history of brain metastases are eligible provided that the metastases have been surgically resected and/or are radiographically and clinically stable for 2 months following the completion of radiation therapy
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to erlotinib
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to cetuximab
- Prior treatment with EGFR-targeting therapies
- Major surgery or significant traumatic injury occurring within 21 days prior to treatment
- Abnormalities of the cornea based on history (e.g., dry eye syndrome, Sjogren's syndrome), congenital abnormality (e.g., Fuch's dystrophy), abnormal slit-lamp examination using a vital dye (e.g., fluorescein, Bengal-Rose), and/or an abnormal corneal sensitivity test (Schirmer test or similar tear production test)
- Gastrointestinal tract disease resulting in an inability to take oral medication or a requirement for IV alimentation, prior surgical procedures affecting absorption, or active peptic ulcer disease
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with erlotinib or cetuximab
- Human immunodeficiency virus (HIV)-positive patients receiving combination anti-retroviral therapy are excluded from the study
