The amount of JNJ 26854165 in the blood will be measured and the effect of JNJ 26854165 on the disease will also be monitored. The effect of food on the absorption, break down and elimination of the drug will be studied in some patients. At some dose levels, the possible interaction of JNJ 26854165 with medications frequently used in cancer patients will be examined and patients at these dose levels will be asked to take a single dose of three additional drugs (dextromethorphan hydrobromide (30mg), tolbutamide (250mg), and midazolam (5mg) "cocktail") on 2 study days, which will all be supplied by the study doctor.
