Study Description(click to expand)

This is a Phase 1/2 multi-center, open label study in solid tumor patients (including glioblastoma) who have a confirmed homozygous MTAP deletion in their tumor. The Phase 1 portion is a dose escalation study of oral TNG908 in patients with confirmed MTAP-deleted solid tumors. In Phase 2, 6 expansion arms defined by confirmed MTAP-deleted tumor types will enroll in parallel at the RP2D of TNG908. In both parts of the study participants who tolerate the drug may continue treatment until disease progression.
