If you are found to be eligible to take part in this study, the study doctor will decide which drug you will receive with valproic acid, based upon your particular disease. You will then begin taking valproic acid plus either dasatinib, erlotinib hydrochloride, lapatinib, lenalidomide, sorafenib, or sunitinib malate. One (1) cycle is either 21 or 28 days long, depending on which study drug combination you receive.
