Clinical Trial Summary

MEK is a critical member of the MAPK pathway involved in growth and survival of cancer cells. PD-325901 is a new drug designed to block this pathway and kill cancer cells. The purpose of this study is to study the effectiveness of PD-325901 in patients with colon cancer, breast cancer, and melanoma. PD-325901 will be given by mouth as a pill twice a day, CT scans will be done and biopsies will be taken of a tumor before and once during treatment to measure the effects of the drug. Blood samples will be taken to measure the amount of drug in the blood.


Clinical Trial Description

The study prematurely discontinued on March 15, 2007 due to a safety concern, specifically ocular and neurological toxicity presented at 10 mg twice-a-day and higher doses. ;
