This is a phase I study of a novel compound P1446A-05. Aim of this study is to identify the the recommended phase II dose of the drug and to determine the nature of adverse effects associated with the drug. P1446A-05 capsules will be given continuously (28 days in each 28 day cycle) to patients suffering from advanced malignancies with no effective treatment available. The dose of the study agent will be lower i.e. 75 mg per day for initial patients. If this dose is found safe, higher dose will be administered to next set of (three to six) patients. This will continued till the safest and best dose is identified. Treatment will be given for 4 cycles and continued further if found effective. Dose schedule may be modified to introduce treatment holiday,if frequent adverse effects are seen on continuous administration.
