Purpose

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, TNG462, is a selective PRMT5 inhibitor administered orally. The study is planned to treat up to 225 participants.

Uncontrolled intercurrent illness that will limit compliance with the study requirements 3. Active infection requiring systemic therapy 4. Currently participating in or has planned participation in a study of another investigational agent or device 5. Impairment of GI function or disease that may significantly alter the absorption of oral TNG462 6. Active prior or concurrent malignancy. 7. Central nervous system metastases associated with progressive neurological symptoms 8. Current active liver disease from any cause 9. Known to be HIV positive, unless all of the following criteria are met: 1. CD4+ count ≥300/μL 2. Undetectable viral load 3. Receiving highly active antiretroviral therapy 10.

Detailed Description

This is a Phase 1/2 multi-center, open label study in solid tumor patients who have a confirmed homozygous MTAP deletion in their tumor. The Phase 1 portion is a dose escalation study of oral TNG462 administered as a single agent and in combination with pembrolizumab 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(s) of TNG462 and in combination. In both parts of the study participants who tolerate the drug may continue treatment until disease progression.
