NCT05887492

Brief Summary

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.

    37 days

  • +3 more secondary outcomes

Study Arms (4)

Dose Escalation

EXPERIMENTAL

Participants with STK11-mutant solid tumors will receive escalating doses of TNG260 in combination with pembrolizumab to estimate the MTD

Drug: TNG260Drug: Pembrolizumab

Dose Expansion in NSCLC with KRAS Mutation

EXPERIMENTAL

Participants with STK11-mutant and KRAS-mutant NSCLC (squamous and non squamous) will receive TNG260 at the identified RP2D in combination with pembrolizumab

Drug: TNG260Drug: Pembrolizumab

Dose Expansion in NSCLC with KRAS Wild type

EXPERIMENTAL

Participants with STK11-mutant and KRAS-wild type NSCLC (squamous and non-squamous) will receive TNG260 at the identified RP2D in combination with pembrolizumab

Drug: TNG260Drug: Pembrolizumab

Dose Expansion in Advanced or Metastatic Solid Tumors

EXPERIMENTAL

Participants with STK11-mutant solid tumors (including but not limited to pancreatic, endometrial, cervical, breast, and carcinoma of unknown primary) will receive TNG260 at the identified RP2D in combination with pembrolizumab

Drug: TNG260Drug: Pembrolizumab
