• Ability of subject to understand and the willingness to sign a written informed consent document
• Subjects must provide a signed informed consent before any screening procedures

Exclusion Criteria

• Subjects who have a previous or concurrent cancer that is distinct in primary site or histology from lung adenocarcinoma, except cervical carcinoma in situ, treated basal cell carcinoma, superficial noninvasive bladder tumors or any previous cancer curatively treated < 2 years before the start of study treatment
• Subjects who have a history or current evidence of bleeding disorder, i.e. any hemorrhage/bleeding event of Common Terminology Criteria for Adverse Events (CTCAE) grade >= 2 within 4 weeks before the start of study treatment
• History of symptomatic metastatic brain or meningeal tumors unless the subject is > 3 months from definitive therapy and has no evidence of tumor growth on an imaging study within 2 weeks prior to study entry; subjects with brain metastases must not be undergoing acute corticosteroid therapy or steroid taper; chronic steroid therapy is acceptable provided that the dose is stable for one month prior to screening
• Subjects who have a history or current evidence of uncontrolled cardiovascular disease including but not limited to the following conditions: * Congestive heart failure of New York Heart Association (NYHA) class III or IV * Unstable angina (symptoms of angina at rest) or new-onset angina within < 3 months before the start of study treatment * Arterial thrombosis, deep vein thrombosis, or pulmonary embolism within < 3 months before the start of study treatment * Myocardial infarction or stroke within < 3 months before the start of study treatment * Pericarditis (any CTCAE grade), pericardial effusion (CTCAE grade >= 2) or pleural effusion (CTCAE grade >= 2) * Cardiac arrhythmia requiring anti-arrhythmic therapy; subjects receiving digoxin, calcium channel blockers except verapamil, or beta-adrenergic blockers except propranolol are eligible at the investigator’s discretion if the dose has been stable for at least 2 weeks before the start of study treatment; subjects with sinus arrhythmia and infrequent premature ventricular contractions are eligible at the investigator’s discretion
• Subjects who have a left ventricular ejection fraction (LVEF) < 50%, as assessed by echocardiogram performed at screening
• Subjects who have a corrected QT (Fridericia's correction formula [QTcF]) interval > 480 milliseconds (ms) (CTCAE grade > 1) determined by the electrocardiogram (ECG) recorder’s algorithm on the screening ECG
• Subjects who have a history or current evidence of uncontrolled hypertension defined as systolic blood pressure > 150 mmHg or diastolic blood pressure > 95 mmHg at screening despite optimal medical management; subjects with a history of mild to moderate hypertension are eligible at the investigator’s discretion if the hypertension is adequately controlled by antihypertensive treatment used at a stable dose for at least 2 weeks before the start of study treatment
• Subjects who have a heart rate >= 100 beats per minute (bpm) or =< 45 bpm determined by the ECG recorder’s algorithm on the screening ECG
• Women who are pregnant or breast-feeding; women of reproductive potential must have a negative serum beta human chorionic gonadotropin (beta-HCG) pregnancy test obtained within 7 days before the start of study treatment
• Subjects who have had a major surgery or significant trauma within 4 weeks before the start of study treatment
• Subjects who have had solid organ or bone marrow transplantation
• Subjects who have a history of hypersensitivity to any of the study drugs or their excipients, or a history of severe hypersensitivity to any other antigen
• Subjects who have a history of human immunodeficiency virus (HIV) infection or subjects who have an active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection requiring treatment due to a theoretical concern that the degree of immune suppression associated with the treatment may result in progression of HIV infection; subjects with chronic HBV or HCV infection are eligible at the investigator’s discretion if the subject is considered non-infectious based on serological markers
• Subjects who have an active clinically serious infection of CTCAE grade >= 2
• Subjects with a non-healing serious wound, ulcer, or bone fracture unrelated to the primary tumor
• Subjects with corneal epitheliopathy or any eye disorder that may predispose the subjects to drug-induced corneal epitheliopathy, or may interfere with diagnosis of treatment-emergent corneal epitheliopathy at the discretion of the investigator in consultation with the ophthalmologist/optometrist; low grades of superficial punctate keratitis, within the range seen in the normal population, should not lead to the exclusion of the patient
• Subjects experiencing unresolved toxicity of previous antitumor therapy which is CTCAE grade > 1 before the start of study treatment, except for alopecia or hemoglobin >= 9.0 g/dL or >= 5.6 mmol/L
• Subjects with any clinical condition that is considered unstable or might jeopardize the safety of the subject and/or influence the subject’s compliance in the study
• Subjects who have received systemic anticancer therapy within 3 weeks before the start of study treatment; mitomycin C or nitrosoureas must be excluded within 6 weeks before the start of study treatment
• Subjects who have received radiotherapy to tumor lesions that would be chosen as target lesions (measurable disease) within 4 weeks before the start of treatment, except if there is objective evidence of progression of the lesion by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 between the prior radiotherapy and the screening CT or magnetic resonance imaging (MRI) scan; palliative radiotherapy to non-target lesions is allowed at the investigator’s discretion
• Use of drugs that inhibit renal tubular secretion (e.g. probenecid and cimetidine) within 2 weeks before the start of study treatment
• Use of strong cytochrome P450 family 3 subfamily A member 4 (3A4) (CYP3A4) inhibitors or strong CYP3A4 inducers within 2 weeks before the start of study treatment
• Subjects who have previously received anetumab ravtansine
• Subjects who are concurrently receiving any other investigational agents
