About this study

Official title: A Phase 1/2, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Efficacy of TNG260 as Single Agent and in Combination With an Anti-PD-1 Antibody In Patients With STK11 Mutated Advanced Solid Tumors

The goal of this interventional clinical trial is to learn about TNG260, a CoREST inhibitor, in combination with pembrolizumab in patients with advanced solid tumors with a known STK11 mutation.

The main question[s] it aims to answer are:

  • the recommended dose for Phase 2
  • to evaluate the safety and tolerability of the combination therapy
  • to determine the pharmacokinetics of TNG260
  • to evaluate the initial antineoplastic activity

Participants will receive study treatment until they experience an undesirable side effect, their disease progresses or until they withdraw consent.

Read the detailed description

This is a first-in-human Phase 1/2, open-label, multicenter, dose-escalation and expansion study designed to determine the maximum tolerated dose and recommended phase 2 dose(s) and evaluate the safety and tolerability, pharmacokinetics, and antineoplastic activity of escalating oral doses of TNG260 when administered with a standard dose of pembrolizumab in participants with locally advanced or metastatic STK11 mutated solid tumors.

Being tested
TNG260, Pembrolizumab
Keywords
STK11, KRAS wild type, LKB1

    Measured: 37 days

  4. Characterize Maximum Observed Plasma Concentration (Cmax) of TNG260

    To characterize the Cmax by measuring the plasma concentrations versus time of TNG260 alone and when administered in combination with pembrolizumab

    Measured: 37 days

  5. Characterize Terminal Half-life (T1/2) of TNG260

    To characterize the T1/2 by measuring the plasma concentrations versus time of TNG260 alone and when administered in combination with pembrolizumab

    Measured: 37 days

  6. Characterize pembrolizumab concentrations when administered with TNG260

    To characterize the pre treatment and trough concentration levels of pembrolizumab when administered in combination with TNG260

    Measured: 43 days

  7. Safety and tolerability of TNG260 by CTCAE 5.0

    To evaluate the safety and tolerability of TNG260 when administered as single agent and in combination with pembrolizumab by measuring the incidence, nature, and severity of AE and SAE graded according to CTCAE v5.0

    Measured: 42 days

  8. To measure changes in histone acetylation when administered with TNG260

    Measure changes in levels of histone acetylation in blood and/or tumor tissue, on study treatment relative to pre-treatment

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TNG260 and Pembrolizumab in people with Non Small Cell Lung Cancer and Solid Tumors, Adult, run by Tango Therapeutics, Inc. at 13 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 10 inclusion and 10 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: under way, not looking for participants, as of the sponsor's last update on 6 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Determine the MTD and RP2D(s) (Phase 1 only) (time frame: 42 days). The study lists 2 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 6 Jul 2026.
