Frequently asked questions about TNG260

What is TNG260 used for?

TNG260 is an investigational small molecule being studied for the treatment of non-small cell lung cancer and other solid tumors. It is currently in Phase 1 clinical development and is not yet approved by the FDA.

What does TNG260 target?

TNG260 targets the CoREST complex, a protein complex involved in gene regulation. By inhibiting this complex, the drug aims to modulate cancer cell behavior, particularly in tumors with STK11 mutations.

Who makes TNG260?

TNG260 is being developed by Tango Therapeutics, Inc., a biopharmaceutical company. The company's stock is traded under the ticker symbol TNGX.

What phase is TNG260 in?

TNG260 is currently in Phase 1 clinical trials. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still undergoing clinical evaluation for safety and efficacy.

What clinical trials is TNG260 in?

TNG260 is being studied in a Phase 1 clinical trial with the identifier NCT05887492. This trial is investigating TNG260 in combination with an anti-PD antibody in patients with STK11-mutated solid tumors, including non-small cell lung cancer.

Is TNG260 the same as other drugs?

TNG260 is a unique investigational compound developed by Tango Therapeutics. No alternative names for this drug have been reported in clinical trial registries.
