Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN except for subjects with liver metastases (mets) for whom ALT and AST should be =< 5 x ULN
International normalized ratio (INR) or prothrombin time (PT) =< 1.5 x ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants
Activated PTT (aPTT) =< 1.5 x ULN unless subject is receiving anticoagulant therapy if PT or PTT is within therapeutic range of intended use of anticoagulant
Female patients of childbearing potential must have a negative pregnancy test documented at time of screening

Female patients who:

Are postmenopausal for at least 1 year before the screening visit, OR
Are surgically sterile, OR
If they are of childbearing potential, agree to use a highly effective method of contraception from the time of signing the informed consent through 4 months after the last dose of study drug, or agree to completely abstain from heterosexual intercourse

Male patients, even if surgically sterilized (i.e., status post-vasectomy), who:

Agree to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug, or
Agree to completely abstain from heterosexual intercourse
Voluntary agreement to provide written informed consent and the willingness and ability to comply with all aspects of the protocol

Exclusion Criteria:

Use of an investigational drug within 21 days prior to the first dose of study drug. Note that to be eligible, any drug-related toxicity should have recovered to grade 2 or less, with the exception of alopecia
Major surgery within the last 4 weeks or radiotherapy within the last 14 days
Patients with leptomeningeal disease are ineligible
Patients with a previous malignancy within the past 2 years (other than curatively treated basal cell carcinoma of the skin, in situ carcinoma of the cervix, or any cancer that is considered to be cured and have no impact on PFS and overall survival [OS] for the current NSCLC)
Concomitant systemic use of anticancer herbal medications. These should be stopped prior to study entry

Patients receiving:

Strong CYP3A inhibitors (including, but not limited to, atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole, grapefruit, grapefruit juice)

Women who are pregnant or breastfeeding
Presence of active gastrointestinal (GI) disease or other condition that will interfere significantly with the absorption, distribution, metabolism, or excretion of study medications
Patients at risk for GI perforation

Clinically significant cardiovascular disease including:

Corrected QT per Fridericia's formula (QTcF) interval > 450 ms for men and > 470 ms for women, symptomatic bradycardia < 45 beats per minute or other significant electrocardiogram (ECG) abnormalities in the investigator's opinion
Clinically uncontrolled hypertension in the investigator's opinion (e.g., blood pressure > 160/100 mmHg; note that isolated elevated readings considered to not be indicative of uncontrolled hypertension are allowed)

Patients who are immunosuppressed (including known human immunodeficiency virus [HIV] infection), have a serious active infection at the time of treatment, have interstitial lung disease/pneumonitis, or have any serious underlying medical condition that would impair the ability of the patient to receive protocol treatment. Patients with controlled hepatitis C, in the investigator's opinion, are allowed. Patients with known hepatitis B must be hepatitis B virus e antigen (HBeAg) and HB viral deoxyribonucleic acid (DNA) negative for enrollment. Note that, because of the high prevalence, all patients in the Asia-Pacific region (except Australia, New Zealand, and Japan) must be tested and, if hepatitis B surface antigen (HBsAg) positive, must be HBeAg and HB viral DNA negative for enrollment

Concurrent condition that in the investigator's opinion would jeopardize compliance with the protocol or would impart excessive risk associated with study participation that would make it inappropriate for the patient to be enrolled
