Inducers of CYP3A4: Anticonvulsants: phenytoin, carbamazepine, phenobarbital, oxcarbazepine Antibiotics: rifampin, rifabutin, rifapentine Miscellaneous: St. John's Wort, modafinil Patients must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to SB-715992 Patients must not have any uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/ social situations that would limit compliance with study requirements Patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy; therefore, HIV-positive patients receiving combination anti-retroviral therapy are not eligible because of possible pharmacokinetic interactions with SB-715992 No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, adequately treated Stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease-free for 5 years
