P13Kinase Inhibitor BKM120 in Combination With Panitumumab in Metastatic/Advanced RAS-Wild Type Colorectal Cancer.

This is done by starting with doses of BKM120 at lower than the usual dose. Patients are given BKM120 and panitumumab and are watched very closely to see what side effects they have and to make sure the side effects are not severe. If the side effects are not severe, then more patients are asked to join the study and are given higher doses of BKM120. If severe toxicity is seen, doses of BKM120 and/or panitumumab doses may be lowered in subsequent patients. Patients joining the study later on will normally get higher doses of BKM120 than patients who join earlier. This will continue until a dose is found that causes severe but temporary side effects. Doses higher than that will not be given.
