Frequently asked questions about TNG456

What is TNG456 used for?

TNG456 is an investigational small molecule being studied in adults with solid tumors, including non small cell lung cancer. It is being evaluated in patients whose tumors show MTAP loss, a biomarker-selected population. TNG456 has not been approved for any indication and remains in clinical development.

What does TNG456 target?

TNG456 targets PRMT5, a protein arginine methyltransferase. The compound is designed to inhibit PRMT5 in tumor cells that have lost the MTAP gene, a biomarker-selected approach. This mechanism is being tested in a Phase 1 study in solid tumors including non small cell lung cancer.

Who is developing TNG456?

TNG456 is being developed by Tango Therapeutics, Inc., which trades on the Nasdaq under the ticker TNGX. The company is running a Phase 1 clinical trial of the drug in patients with solid tumors characterized by MTAP loss.

What phase is TNG456 in?

TNG456 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA for any indication. The ongoing Phase 1 trial is evaluating safety and tolerability in patients with solid tumors with MTAP loss.

What clinical trials is TNG456 in?

TNG456 is being studied in one active clinical trial, NCT06810544, titled Safety and Tolerability of TNG456 Alone and in Combination With Abemaciclib in Patients With Solid Tumors With MTAP Loss. The Phase 1 study is recruiting in the United States and has an enrollment target of 191 participants.

Is TNG456 being studied in non small cell lung cancer?

Yes. Non small cell lung cancer is among the conditions included in the Phase 1 trial of TNG456, NCT06810544. The study enrolls adults with solid tumors showing MTAP loss and also includes glioma, glioblastoma multiforme, brain tumor, and other solid tumor types.
