Bevacizumab, Erlotinib, and Capecitabine for Locally Advanced Rectal Cancer
The goal of this clinical research study is to find the highest tolerable dose of bevacizumab (Avastin) and erlotinib hydrochloride (Tarceva) that can be given in combination with standard radiation therapy and capecitabine before surgery to patients with rectal cancer. The safety and effectiveness of this combination of therapies will also be studied.
The goal of this Phase I trial was to determine the maximal tolerated dose (MTD) of concurrent capecitabine, bevacizumab and erlotinib with preoperative radiation therapy (RT) for rectal cancer. The trial completed as Phase I without progressing to the Phase II portion.

|Official Title:||Phase I/II Trial of Preoperative Radiotherapy With Concurrent Bevacizumab, Erlotinib and Capecitabine for Locally Advanced Rectal Cancer|
- Maximal tolerated dose (MTD) [ Time Frame: Continuoual Reassessment Weeks 1- 6 ]MTD derived from differing dose combinations of Capecitabine, Bevacizumab, and Erlotinib of using the continual reassessment method (CRM). Dose limiting toxicity defined as any grade 3 or higher acute toxicity during chemoradiation. The MTD will be defined as the dose at which grade 3 or higher acute toxicity exceeds 25%.
