Overview
Brief Summary
This is a first in human study in patients with advanced or metastatic solid tumors known to have an MTAP deletion. The first part of the study is an open-label, dose escalation and the second part is an open label dose expansion in specific MTAP-deleted tumor types. The study drug, TNG908, is a selective PRMT5 inhibitor administered orally. The study is planned to treat up to 192 participants.
Detailed Description
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.

Outcomes
Primary Outcomes
Phase 1:
Time Frame: 28 days
To determine the MTD and dosing schedule of TNG908
