Mildly elevated total bilirubin (\<6 mg/dL) is allowed if Gilbert's syndrome is documented.~* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN (≤5 x ULN for subjects whose cancer involves their liver including liver metastasis)~* Alkaline phosphatase limit ≤ 2.5 x ULN (≤ 5 x ULN for subjects whose cancer involves their liver including liver metastasis).~* Estimated glomerular filtration rate (eGFR) ≥ 50 mL/min as calculated using the Cockcroft-Gault formula~* International normalized ratio (INR) ≤ 1.5 x ULN. Subjects who are being treated with heparin are allowed to participate.~Exclusion Criteria:~* Prior treatment with erlotinib. Patients permanently withdrawn from study participation will not be allowed to re-enter the study.~* Symptomatic metastatic brain or meningeal tumors unless the patient is \> 6 months from definitive therapy, has no evidence of tumor growth on an imaging study within 4 weeks prior to study entry and is not on dexamethasone and clinically stable with respect to the tumor at the time of study entry.~* Major surgery, open biopsy, or significant traumatic injury within 28 days before starting the study treatment~* History of organ allograft~* Non-healing wound, skin ulcer, or bone fracture~* Uncontrolled concurrent medical illness including uncontrolled hypertension defined as systolic blood pressure \>150 millimeter of mercury (mmHg) or diastolic blood pressure \>90 mmHg, despite medical management~* History of cardiac disease: congestive heart failure \> NYHA (New York Heart Association) Class II; unstable angina (symptoms of angina at rest), new-onset angina (within the last 3 months), myocardial infarction within the past 6 months prior to screening (Visit 1); cardiac ventricular arrhythmias requiring anti-arrhythmic therapy (except for beta-blockers and digoxin)~* Pleural effusion or ascites that causes respiratory compromise (NCI-CTCAE version 4.0 Grade ≥ 2 dyspnea)~* Interstitial lung disease with ongoing signs and symptoms within 28 days before starting the study treatment~* Arterial or venous thrombotic or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 6 months before the start of study medication~* Subjects with evidence or history of bleeding diathesis; any hemorrhage or bleeding event CTCAE Grade ≥ 3 or higher within 4 weeks of start of investigational treatment~* Dehydration CTCAE Grade ≥ 1~* Unresolved toxicity higher than NCI-CTCAE version 4.0 Grade 1 (excluding alopecia, anemia or lymphopenia) attributed to any prior systemic or radiation therapy or other medical or surgical procedure~* Known hypersensitivity to erlotinib, study drug class, or excipients in the formulation~* Ongoing or active infection (bacterial, fungal, or viral, e.g. human immunodeficiency virus (HIV)) of NCI-CTCAE version 4.0 Grade ≥ 2~* Seizure disorder requiring anticonvulsant therapy (such as steroids or anti-epileptics)~* Pregnancy and lactation (breast feeding)~* During the study, no other anticancer treatment, including any investigational new drugs, is allowed. Anticancer therapy is defined as any agent or combination of agents with clinically proven anticancer activity. Systemic anticancer therapy including cytotoxic therapy, signal transduction inhibitors, immunotherapy, and hormonal therapy during this trial or within 28 days or 5 drug half-lives (if drug half-life in subjects is known), whichever is shorter (or within 6 weeks for mitomycin C) before start of the study treatment.~* Use of hematopoietic growth factors, such as G-CSF (granulocyte colony-stimulating factor), GM-CSF (granulocyte-macrophage colony-stimulating factor), erythropoietin, and interleukin (Il-2, IL-3), within 3 weeks prior to first dose. G-CSF and other hematopoietic growth factors may be used in the management of acute toxicity such as febrile neutropenia when clinically indicated or at the discretion of the investigator; however, they may not be substituted for a required dose reduction. Subjects taking chronic erythropoietin consistent with institutional guidelines can be included.~* Close affiliation with the investigational site; e.g. a close relative of the investigator or a dependent person (e.g. employee or student of the investigational site)~* Substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results~* Inability to swallow oral medications~* Inflammatory bowel disease or other disorders associated with chronic diarrhea

Study Arms:
- Increasing dose of Theophylline (Type: EXPERIMENTAL): Patients will be put on the standard dose of 150 mg/day of erlotinib. Patients will be entered into the study on different dose levels of theophylline (100 mg/bid, 150 mg/bid, 200 mg/bid, or 200 mg/tid) for 28 days to find what is the lowest dose that effectively controls the diarrhea caused by erlotinib.
- Increasing dose of erlotinib (Type: EXPERIMENTAL): Patients will be kept on a specified dose of theophylline while the dose of erlotinib increases in each group of patients enrolled (200 mg/qd, 225 mg/qd, or 250 mg/qd) for 28 days to determine what the maximum dose of erlotinib that can be given with theophylline and maintain a safety profile.

Based on this trial design, predict the completion outcome and termination type (if applicable).
