Clinical Trial Summary

Phase I Study of NT-112, an autologous T-cell therapy product genetically engineered to express an HLA-C*08:02-restricted T cell receptor (TCR), targeting KRAS G12D mutant solid tumors.

Description:

This is a Phase 1, open-label, multicenter study to evaluate the safety and preliminary antitumor activity of NT-112 in HLA-C*08:02 subjects with unresectable, advanced, and/or metastatic NSCLC, colorectal adenocarcinoma, pancreatic adenocarcinoma, endometrial cancer, or any other solid tumor histology that is positive for the KRAS G21D mutation.
