Part of the treatment plan for this study is surgical removal of the tumor that is planned to occur 6 to 8 weeks after completion of radiotherapy (XRT). This study consists of 2 distinct phases (Phase 1 and Phase 2).
In Phase 1, the objectives are to
1. Assess dose-limiting toxicities (DLTs) and
2. Determine a maximum-tolerated dose (MTD)
The Phase 1 endpoints are assessed on an initial cohort of patients after the completion of the chemo-radiotherapy regimen at defined timepoints that precede surgery.
Phase 2 is the efficacy assessment portion of this study. In Phase 2, the objective is to accrue an expansion cohort. Efficacy assessments for phase 2 are to be assessed across all study participants at the time of, or after, surgery, as measured by the pathologic response rate; downstaging; and survival at 5 years from the start of treatment.
