Phase I Trial of Ganetespib, Capecitabine, and Radiation in Rectal Cancer

Summary

The purpose of this study is to find out what effects, good and/or bad, the combination of the study drug, capecitabine, and radiation have on you and your cancer. Capecitabine, radiation, and the study drug kill cancer cells in different ways. Giving these treatments together may make your cancer shrink or slow down its growth more than it would if you got treated with capecitabine and radiation alone. This is a Phase I drug study of ganetespib given together with capecitabine and radiation in patients with locally advanced rectal cancer. Ganetespib is an experimental drug; not approved by the Food and Drug Administration (FDA). The other two, capecitabine and radiation, are approved by FDA for use in rectal cancer. In this study, the investigators will test different dosages of the "investigational" (experimental) drug, called ganetespib (the study drug). The study drug is "investigational" because it is not approved by the FDA for use. The study drug has been previously tested in humans. The study uses a well-established process of slowly increasing drug dosage to determine the highest dosage that can be given without causing serious side effects. In addition, the study will help researchers to determine what the side effects and drug interactions might be. The study will also look at the drug's pharmacokinetics (PK). PK is how the study drug and capecitabine with radiation work in your body (for example how long the drugs last in your body.)
