The Efficacy and Safety of Neoadjuvant Therapy With Iparomlimab and Tuvonralimab in Locally Advanced MSI-H/dMMR Colorectal Cancer: An Prospective, Single-Arm Study (Neo-IT)

Summary

Immunotherapy may bring revolutionary changes to the preoperative neoadjuvant treatment mode for dMMR/MSI-H locally advanced rectal cancer. According to the existing theory, the use of Iparomlimab and Tuvonralimab may be the best solution. In this study, the investigators will perform single-cell sequencing of participants tissue samples, fully explore the multi-dimensional omics information of tumors and microenvironments, explore the characteristics of the treatment benefit population, and try to construct an efficacy prediction model to screen the treatment benefit population early and implement precise treatment.
