Dose EscalationEXPERIMENTALParticipants with STK11-mutant solid tumors will receive escalating doses of TNG260 in combination with pembrolizumab to estimate the MTD
Dose Expansion in NSCLC with KRAS MutationEXPERIMENTALParticipants with STK11-mutant and KRAS-mutant NSCLC (squamous and non squamous) will receive TNG260 at the identified RP2D in combination with pembrolizumab
Dose Expansion in NSCLC with KRAS Wild typeEXPERIMENTALParticipants with STK11-mutant and KRAS-wild type NSCLC (squamous and non-squamous) will receive TNG260 at the identified RP2D in combination with pembrolizumab
Dose Expansion in Advanced or Metastatic Solid TumorsEXPERIMENTALParticipants 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
