TPS814Background: Improvements in outcomes for locally advanced rectal cancer (LARC) have plateaued due to an inability to consistently deliver adjuvant therapy and thus far ineffective novel therapies. Systematic testing of new chemotherapy and radiation sensitizers are needed to advance treatment outcomes. This randomized phase II modular clinical trial platform utilizes Total Neoadjuvant Therapy (TNT) with parallel experimental arms in LARC. The experimental arms are not intended for direct comparison, but to test a variety of sensitizers or hypotheses in a consistent and relatively homogenous high-risk patient (pt) population with correlative biomarkers. Success of any given experimental arm will be determined by achievement of pathologic endpoints compared to a control arm. Methods: This NCTN multi-arm randomized phase II trial serves as a modular platform to assess novel sensitizers to neoadjuvant chemotherapy and/or chemoradiotherapy (chemoRT) in LARC. Eligibility includes LARC as defined by any ON...
