Neoadjuvant Weekly Paclitaxel and Biomarkers of Therapy Response
University of Wisconsin, Madison
Summary
The hypothesis of this study is that paclitaxel levels increase chromosomal instability (CIN) in tumors and this is lethal to tumors that have pre-existing CIN. Treatment will be administered on an outpatient basis. Paclitaxel will be initiated as standard infusions on days 1, 8, and 15 of a 21-day cycle. Participants will continue with paclitaxel for cycles 2-4 prior to surgery.
Description
Primary Objectives * To test if cancers with high chromosomal instability (CIN) respond to paclitaxel better than low CIN cancers. Secondary Objectives * To identify patient-specific differences in tumor levels and distribution of paclitaxel at 20 hours after first dose and patient-specific differences in peripheral non-tumor tissue (skin or plasma) paclitaxel levels 20 ± 4 hours after first dose. * To determine if paclitaxel levels are higher at 20h after the 3rd dose than after the first dose, and if levels are higher at 20h after the 10th, 11th, or 12th dose than the 1st and 3rd dose. *…
