About this study
Official title: A Phase 1/2, Multicenter, Open-Label Study to Evaluate the Safety, Tolerability, and Preliminary Antitumor Activity of TNG456 Monotherapy and in Combination With Abemaciclib in Patients With Solid Tumors With MTAP Loss
This is a first in human study of TNG456 alone and in combination with abemaciclib in patients with advanced or metastatic solid tumors known to have an MTAP loss. The first part of the study is an open-label, dose escalation and the second part is an open label dose expansion in specific solid tumor types with a confirmed MTAP loss. The study drug, TNG456, is a selective PRMT5 inhibitor administered orally. The study is planned to treat up to 191 participants.
Read the detailed description
This is a Phase 1/2 multi-center, open label study in solid tumor patients who have a confirmed MTAP loss in their tumor. The Phase 1 portion is a dose escalation study of oral TNG456 administered as a single agent and in combination with oral abemaciclib in solid tumor patients with confirmed MTAP loss. In the Phase 2 expansion part of the study, 6 arms defined by confirmed tumor types will enroll in parallel at the RP2D(s) of TNG456 and in combination. In both parts of the study participants who tolerate the drug may continue treatment until disease progression.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing TNG456 and abemaciclib in people with Non Small Cell Lung Cancer and Glioma Glioblastoma Multiforme, run by Tango Therapeutics, Inc. at 15 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 21 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Adam Crystal, MD, PhD ((857) 320-4899, clinicaltrials@tangotx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Phase 1 Maximum Tolerated Dose (time frame: 21 days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2026.
