Docetaxel and Lapatinib in Metastatic Transitional Cell Carcinoma in Bladder

Inclusion Criteria:

* Histologically or cytologically confirmed transitional cell carcinoma of the urothelium (also called urothelial cancer); mixed histologies are allowed as long as the predominant histology is TCC; in addition, tumor tissue must be available for evaluation for EGFR and HER2/neu status
* Locally recurrent or advanced, non-resectable or stage IV transitional cell carcinoma
* Must have had prior platinum salt-based chemotherapy for TCC; other prior systemic chemotherapeutic or investigational treatment regimens for TCC are allowed; patient may have had up to three lines of chemotherapy for advanced disease; may have had paclitaxel provided their cancer did not progress while on it, and it was part of an adjuvant or neoadjuvant regimen; prior targeted or biological therapy is permitted except for drugs targeting EGFR and/or HER2; specifically, subjects must meet one or more of the following criteria: (a). Progression after treatment with a regimen that includes a platinum salt (e.g. carboplatin or cisplatin) for Stage IV or recurrent disease OR (b). Disease recurrence within two years (from the date of last dose of chemotherapy or surgery until day the informed consent is signed) of neoadjuvant or adjuvant treatment with a regimen that includes a platinum salt
* Measurable or evaluable disease, as defined by Response Evaluation Criteria In Solid Tumors (RECIST) 1.1; if all sites of measurable or evaluable disease have been irradiated, one site must have demonstrated growth after irradiation
* A left ventricular ejection fraction (LVEF) within normal range as measured by echocardiogram or multi-gated acquisition (MUGA) scan
* Adequate contraceptive method for subjects with reproductive potential (females with reproductive potential must have a negative serum pregnancy test within 7 days of study entry)
* Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
* A signed written informed consent
* Due to the experimental nature of lapatinib, female subjects must be one year postmenopausal, surgically sterile, or using an acceptable method of contraception (oral contraceptives, barrier methods, approved contraceptive implant, long-term injectable contraception, intrauterine device or tubal ligation); male subjects must be surgically sterile or using an acceptable method of contraception during their participation in this study

Exclusion Criteria:

* History of treatment of TCC (in any setting - neoadjuvant, adjuvant or for metastatic disease) with docetaxel
* History of treatment with an EGFR or HER2 targeted agent
* Serum bilirubin more than 1.5 x the upper limit of normal (ULN) except in patients with diagnosis of Gilbert's disease
* Creatinine clearance less than 20 mL/minute (calculated by the Cockcroft-Gault formula)
* Potassium, less than institutional normal level despite supplementation; serum calcium (ionized or adjusted for albumin,) or magnesium below lower limits of normal despite supplementation
* Baseline liver function test including AST or ALT greater than 2.5 x institutional upper limits of normal.
* Absolute neutrophil count (ANC) less than 1500/uL
* Platelets less than 100/uL
* Evidence of severe or uncontrolled systemic disease or any concurrent condition which in the Investigator's opinion makes it undesirable for the subject to participate in the trial or which would jeopardize compliance with the protocol
* An abnormal left ventricular ejection fraction LVEF as measured by echocardiogram or MUGA scan or other suitable technique
* Clinically significant cardiac event such as myocardial infarction; New York Heart Association (NYHA) classification of heart disease more than class 2 within 3 months before entry; or presence of cardiac disease that, in the opinion of the Investigator, increases the risk of ventricular arrhythmia
* History of arrhythmia (multifocal premature ventricular contractions \[PVCs\], bigeminy, trigeminy, ventricular tachycardia, or uncontrolled atrial fibrillation) which is symptomatic or requires treatment (Common Terminology Criteria for Adverse Events \[CTCAE\] grade 3) or asymptomatic sustained ventricular tachycardia; atrial fibrillation controlled on medication is not exclusion nor are infrequent or unifocal ectopic beats
* Current QTc prolongation as a result of medication will require discontinuation of that medication; the patient can be reassessed after discontinuation, provided this is medically appropriate, after 2 weeks or five half-lives of the drug have passed whichever is longer
* Congenital long QT syndrome or 1st degree relative with unexplained sudden death under 40 years of age
* Presence of left bundle branch blocks (LBBB)
* QTc with Bazett's correction that is unmeasurable, or exceeds 480 msec on screening electrocardiogram (ECG); if a subject has QTc \> 480 msec on screening ECG, the screen ECG may be repeated twice (at least 24 hours apart); the average QTc from the three screening ECGs must be \< 480 msec in order for the subject to be eligible for the study
* Any concomitant medication that may cause QTc prolongation, induce Torsades de Pointes or induce cytochrome P450 3A4 (CYP3A4) function
* Hypertension not controlled by medical therapy
* Currently active diarrhea
* Women who are currently pregnant or breast feeding
* Receipt of any investigational agent, chemotherapy or radiation therapy within 21 days prior to Study Day 1
* Any unresolved non-hematologic toxicity greater than CTCAE grade 1 from previous anti-cancer therapy (other than alopecia)
* Major surgery within 4 weeks or incompletely healed surgical incision before starting study therapy
* Grade 2 or greater peripheral neuropathy
* Previous or current malignancies within the last 3 years, with the exception of in situ carcinoma of the cervix, adequately treated carcinoma of the skin, small renal masses, and adequately treated localized prostate cancer; other cancers that are highly likely to be cured (cure rate of 75% or greater) may be included at the discretion of the Principal Investigator
* History of severe hypersensitivity reaction to drugs formulated with polysorbate 80
* Patients with brain metastasis can only be included if they were treated more than 4 weeks prior to enrollment; subjects with treated brain metastases must have a post treatment brain magnetic resonance imaging (MRI) showing no further progression of prior lesions AND no new metastatic lesions; subjects will be ineligible if they have any ongoing symptoms from brain metastases or if there continues to be radiographic evidence of cerebral edema
