What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 30 participants in total. It began in 2025-04-29 with a primary completion date of 2027-10.

Brief Summary

The purpose of this study is to determine the overall safety and tolerability of JBI-802 as single agent and in combination with Pembrolizumab.

Eligibility Criteria

Inclusion Criteria: 1. Males or females aged ≥18 years at Screening. 2. Participants with a histologically confirmed diagnosis of locally advanced or metastatic NSCLC harboring an STK11 mutation. 3. Screening laboratory values: * Absolute neutrophil count (ANC) ≥1500 cells/mm3. * Platelet count ≥100,000 cells/mm3. * Total bilirubin ≤1.5×ULN. Patients with Gilbert's syndrome may be enrolled with up to 3.0xULN. * AST and ALT ≤2.5×ULN (unless liver metastases are present then up to 5×ULN is allowed). * Calculated creatinine clearance (CrCL) ≥40 mL/min calculated per Institutional standard. * Prothrombin time (PT) or activated partial thromboplastin time (aPTT) * 1.5×ULN if participant is not anticoagulated (Note: If participant is on anticoagulants, the participant must be on a stable dose for at least 2 weeks prior to study entry. 4. Must have at least one measurable lesion on CT scan or MRI per RECIST 1.1 5. Resolution of any clinically significant toxic effects of prior therapy to Grade 0 or 1 according to the NCI CTCAE, Version 5.0 (exception of alopecia and Grade 2 peripheral neuropathy, chronic Grade 2 endocrinopathies as a result of prior immunotherapy). 6. Eastern Cooperative Oncology Group (ECOG) performance status of ≤2. 7. Able to swallow oral medication. 8. Willing and able to give informed consent and comply with protocol requirements for the duration of the study. 9. Willingness to use contraception by a method that is deemed effective by the Investigator by both males and female participants of childbearing potential (post-menopausal women must have been amenorrheal for at least 12 months to be considered of non-childbearing potential) and their partners throughout the treatment period and for at least 3 months following the last dose of study drug. Exclusion Criteria: 1. Treatment with systemic anticancer therapy or an investigational agent within 2 weeks or 5 half-lives, whichever is shorter, prior to start of study drug treatment. 2. Major surgery ≤21 days prior to starting study drug or has not recovered from adverse effects of such procedure. 3. Surgery (eg, stomach bypass) or medical condition that might significantly affect absorption of medicines (as judged by the Investigator). 4. Radiotherapy within 2 weeks prior to start of study drug treatment (palliative radiation or stereotactic radiosurgery within 7 days prior to start of study treatment). Participants must have recovered from all radiotherapy-related toxicities. 5. Known malignant central nervous system disease other than neurologically stable, treated brain metastases- defined as metastasis having no evidence of progression or hemorrhage for at least 4 weeks after treatment (including brain radiotherapy). Must be off any systemic corticosteroids for the treatment of symptomatic brain metastases for at least 14 days prior to enrollment. 6. Severe or unstable medical condition, such as congestive heart failure (New York Heart Association \[NYHA\] Class III or IV), ischemic heart disease, uncontrolled hypertension, uncontrolled diabetes mellitus, psychiatric condition, as well as an uncontrolled cardiac arrhythmia requiring medication (≥Grade 2, according to NCI CTCAE Version 5), myocardial infarction within 6 months prior to starting study treatment, or any other significant or unstable concurrent cardiac illness. Note: Stable chronic atrial fibrillation is allowed. 7. Congenital long QT syndrome or corrected QT interval by Fridericia (QTcF) interval \>480 msec for males and females, respectively, at Screening. 8. History of other previous or concurrent cancer that would interfere with the determination of safety or efficacy assessment with respect to the qualifying solid tumor malignancy. 9. Live vaccines within 30 days prior to the first dose of JBI-802. 10. Glucocorticoids for any purpose other than to modulate symptoms from an event of clinical interest) or for use as a premedication in participants with a known history of an IV contrast allergy administered as part of CT radiography. Inhaled, intranasal, intraocular, topical, and intraarticular joint injections of steroids are permitted. 11. Use of strong inhibitors of cytochrome P450 3A (CYP3A) within 14 days or 5 half-lives (whichever is longer) or grapefruit juice or grapefruit containing products within 7 days prior to Cycle 1 Day 1. 12. Use of strong inducers of CYP3A within 14 days or 5 half-lives (whichever is longer) prior to Cycle 1 Day 1. 13. Use of strong inhibitors of cytochrome CYP2D6 within 14 days or 5 half-lives (whichever is longer) prior to Cycle 1 Day 1. 14. Use of strong inducers of CYP2D6 within 14 days or 5 half-lives (whichever is longer) prior to Cycle 1 Day 1. 15. Major active infection requiring parenteral antibiotics. 16. Known active human immunodeficiency viruses infection or active infection with hepatitis B or C. 17. Active gastrointestinal disease (eg, Crohn's disease, ulcerative colitis, or short gut syndrome) or other malabsorption syndromes that would reasonably impact drug absorption. 18. Acute illness within 14 days prior to IP dosing unless mild in severity and approved by the Principal Investigator. 19. Presence of active infection requiring antibiotics. 20. Pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the trial, starting with the Screening Visit through 90 days after the last dose of trial treatment. 21. Current participation in another clinical study of an investigational agents. Simultaneous participation in observational studies is acceptable after Principal Investigator approval.
