Exclusion Criteria: Have previously completed or withdrawn from this study or any other study investigating dasatinib. Prior treatment with other tyrosine kinases, including afatinib, is acceptable. Prior recent systemic or investigational therapy within 21 days of initiation of study treatment. An exception is that epidermal growth factor receptor (EGFR) inhibitor may be continued up until 3 days of initiation of study treatment. Women who are pregnant or breastfeeding. Women of childbearing potential must have a negative pregnancy test (β-HCG test in urine or serum) prior to commencing study treatment. Patients with documented central nervous system or leptomeningeal metastasis (brain metastasis) at the time of study entry. Patients with prior brain metastasis may be considered if they have completed their treatment for brain metastasis and no longer require corticosteroids. Patients with disease progression in the central nervous system (CNS) only. Serious concomitant disorder, including active bacterial, fungal, or viral infection, incompatible with the study (at the discretion of the principal investigator). Uncorrected severe electrolyte disorder, including severe potassium (<3.0 mEq/L) or magnesium ( < 1.0 mEq/L) deficiency. Any gastrointestinal disorder with diarrhea as a major symptom, such as Crohn's, or pre-existing chronic diarrhea Common Toxicity Criteria (CTC) Grade ≥ 2 of any etiology. Included are malabsorption disorders that in the opinion of the study physician may affect absorption of either afatinib or dasatinib. Prior major surgery or radiation therapy within 14 days of initiation of treatment. Electrocardiogram (ECG) abnormalities indicative of arrhythmia (at the discretion of the investigator). History or presence of clinically relevant cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure New York Heart Association (NYHA) classification of 3, unstable angina or poorly controlled arrhythmia. Myocardial infarction within 6 months prior to enrollment. Baseline (< 1 month before treatment) cardiac left ventricular function with resting ejection fraction of less than 50% measured by multigated blood pool imaging of the heart (MUGA scan) or echocardiogram. Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, congenital long QT syndrome, or Torsades de pointes). Prolonged QTc interval on pre-entry electrocardiogram (> 470 msec for men and >480 msec for women per American College of Cardiology/American Heart Association [AHA/ACC] 2011 scientific statement). History of significant bleeding disorder unrelated to cancer, including diagnosed congenital bleeding disorders (e.g., von Willebrand's disease). Patients currently taking drugs that are generally accepted to have a high risk of causing Torsades de Pointes. Patients with pre-existing interstitial lung disease (ILD), or pericardial / pleural effusion of grade 2 or higher. Trace pericardial or pleural effusion is acceptable. Patients who require chronic oxygen therapy for chronic obstructive pulmonary disease or pleural effusions (malignant or benign). Patients requiring comedication with potent P-gp inhibitors (including cyclosporin, azithromycin, erythromycin, ketoconazole, itraconazole, quinidine, phenobarbital salt with quinidine, ritonavir, valspodar, verapamil) or inducers (including rifampicin). Known active hepatitis B infection, known active hepatitis C infection, or known HIV carrier. Known or suspected active drug or alcohol abuse. Known hypersensitivity to afatinib, dasatinib, or the excipients of any of the trial drugs. Laboratory exclusion criteria: Absolute neutrophil count (ANC) < 1000 / mm^3, Platelet count < 100,000 / mm^3, Serum creatinine ≥1.5 times the upper normal limit or calculated/measured creatinine Clearance ≤60 mL/min., Total bilirubin ≥1.5 mg/dL (>26 mol/L, SI unit equivalent), Aspartate amino transferase (AST) or Alanine amino transferase (ALT) ≥ 2.5 times the upper limit of normal (if related to liver metastases ≥ five times the upper limit of normal).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Tolerated Dose (MTD) of Afatinib (BIBW 2992) in Combination With Dasatinib | The MTD for this combined treatment will be defined as either: The highest dosage cohort in which six patients had been treated and there were less than two dose limiting toxicities (DLTs) or, Afatinib at the highest tolerated dose investigated (40 mg by mouth [PO] daily) plus dasatinib at the highest tolerated dose investigated (cohort 3, 140 mg PO daily). | Up to 6 Months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Objective Response | Estimates objective response rate (complete response [CR] and partial response [PR]) in participants with acquired EGFR resistance | Up to 6 Months | 
| Median Progression Free Survival | Estimate the 6-month progression free survival (PFS) rate in participants with acquired EGFR resistance. Response Criteria for Phase 1B will follow RECIST v.1.1: Progressive Disease (PD) is defined as at least a 20% increase in the sum of LD of target lesions taking as references the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. | Up to 6 Months |
