If you are enrolled in Part B or Part C, you will have tumor biopsies. If you have tumors that can be felt under the skin, the biopsy may will be done after a local anesthetic is used to numb the skin. If the tumor is not detectable by touch, you would have the biopsy performed with the help of a CT scan or ultrasound. The first biopsy will be within 4 weeks before starting LY2275796. You will then have 1 more biopsy between 21-28 days after you start taking LY2275796. The first biopsy taken before you receive the study drug is to get a baseline evaluation of the tumor. The biopsy taken after you receive the study drug is to check the level of the study drug in the tumor and also to see if the drug is working in the cancer cells as it is expected to do.
