AZD2171 in Treating Patients With Recurrent Small Cell Lung Cancer

Inclusion Criteria

• Patients must have histologically or cytologically confirmed small cell lung cancer
• Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques or as >= 10 mm with spiral CT scan
• Patients must have received prior platinum-based chemotherapy; no more than 1 prior chemotherapy regimen is allowed
• Life expectancy of greater than 12 weeks
• Karnofsky performance status >= 50%
• Leukocytes >= 3,000/mcL
• Absolute neutrophil count >= 1,500/mcL
• Platelets >= 100,000/mcL
• Hemoglobin >= 8 g/dL
• Total bilirubin within normal institutional limits
• AST(SGOT)/ALT(SGPT) = >= 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
• At present, the potential of AZD2171 for clinically significant drug interactions involving the CYP isozymes is unknown; the only documented interaction is with CYP IA agents/drugs; the other reported interactions were not seen in the dose ranges studied and appears to occur at levels far beyond what can be and will be delivered clinically; patients receiving CYP interactive concomitant medications should not be excluded from study, but those agents/drugs should be documented along with any associated AEs that occur; efforts should be made to switch patients with gliomas or brain metastases who are taking enzyme-inducing anticonvulsant agents to other medications
• AZD2171 has been shown to terminate fetal development in the rat, as expected for a process dependent on VEGF signaling; for this reason, women of child-bearing potential must have a negative pregnancy test prior to study entry; women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
• Ability to take oral medications on a regular basis
• Ability to understand and the willingness to sign a written informed consent document
• The following groups of patients will be considered to be at high risk for compromised left ventricular ejection fraction (LVEF): prior treatment with anthracyclines, prior treatment with trastuzumab, NYHA classification of, class II heart failure controlled with appropriate therapy, prior central thoracic radiotherapy including RT to the heart and history of myocardial infarction within 12 months; these patients are eligible for the study, but will require close monitoring

Exclusion Criteria

• Patients who have had chemotherapy, radiotherapy, or major surgery within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
• Patients may not be receiving any other investigational agents nor have participated in an investigational trial within the past 30 days
• Patients may not be receiving any medication that may markedly affect renal function (e.g., vancomycin, amphotericin, pentamidine)
• Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
• Mean QTc > 500 msec (with Bazett's correction) in screening electrocardiogram or history of familial long QT syndrome
• Greater than +1 proteinuria on two consecutive dipsticks taken no less than 1 week apart
• Uncontrolled intercurrent illness including, but not limited to hypertension, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requ
