Platelets >= 100,000/uL
Total bilirubin =< upper limit of normal (ULN)
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 1.5 x ULN (ALT and AST =< 2.5 x ULN is acceptable if there is liver metastasis)
Calculated or measured creatinine clearance >= 45 mL/min
Patients of child-bearing potential must agree to use acceptable contraceptive methods (e.g., double barrier) during treatment and have a negative serum or urine pregnancy test done =< 7 days prior to registration (for women of childbearing potential only)
Life expectancy >= 12 weeks
Willingness to provide the blood specimens as required by the protocol; please note that the willingness to participate pertains only to the patient and does not factor in the institution's ability to participate in any part of the translational component

Exclusion Criteria:

Patients with any known endothelial growth factor receptor (EGFR) mutation and/or anaplastic lymphoma receptor tyrosine kinase (ALK) translocation
Symptomatic, untreated, or uncontrolled central nervous system (CNS) metastases or seizure disorder; patients with asymptomatic CNS metastases treated with whole brain radiation (WBRT) or gamma knife radiosurgery (GKR) may be enrolled >= 1 week after completion of WBRT/GKR provided toxicities are =< Common Toxicity Criteria (CTC) grade I at the time of registration and/or controlled with dexamethasone 2 mg once daily for at least 5 days at the time of study treatment; patients with symptomatic CNS metastases treated with WBRT/GKR may be enrolled >= 2 weeks after completion of WBRT/GKR provided toxicities are =< CTC grade 1 at the time of registration and neurologic symptoms controlled with dexamethasone =< 2 mg once daily for at least 1 week at the time of study treatment
Patients receiving palliative radiation to skeletal metastases may be registered as early as 1 week after completion of radiation therapy provided toxicities are =< CTC grade I at the time of registration

Any of the following prior therapies for malignancy:

Systemic chemotherapy =< 4 weeks prior to registration
Radiation therapy =< 4 weeks prior to registration (exceptions noted in the prior bullet); the site of previous radiotherapy should have evidence of progressive disease if this is the only site of disease
Major surgery (i.e., laparotomy), open biopsy, or significant traumatic injury =< 4 weeks prior to registration; minor surgery =< 2 weeks prior to registration; insertion of a vascular access device is not considered major or minor surgery in this regard
Other investigational agent =< 30 days prior to study treatment

The following patients will be excluded from this study:

Pregnant women
Breastfeeding women
Men or women who are sexually active and unwilling to use a medically acceptable method of contraception (e.g., such as implants, injectables, combined oral contraceptives, some intrauterine devices or vasectomized partner for participating females, condoms for participating males) during the trial and for at least three months after end of active therapy; a highly effective method of birth control is defined as one which results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly; patients will be considered to be of childbearing potential unless surgically sterilized by hysterectomy or bilateral tubal ligation/salpingectomy, or post-menopausal for at least 2 years

Second primary malignancy with the following exceptions which are allowed:

Carcinoma in situ of the cervix

Human immunodeficiency virus (HIV)-positive patients receiving combination anti-retroviral therapy are excluded because of possible pharmacokinetic interactions with oral investigational agents
