Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed Informed Consent Form (ICF)
• Age ≥ 18 years at time of signing ICF
• Ability to comply with the study protocol, in the investigator's judgment
• Histologically or cytologically confirmed advanced non-squamous NSCLC that is not amenable to definitive therapy
• Tumor PD-L1 expression (TPS ≥ 1%) (cohort A only)
• EGFR, ALK, ROS1 wild-type (cohort A only)
• Confirmed activating alteration in EGFR (cohort B only)
• Disease progression during or following treatment with anti-PD(L)1 containing therapy (cohort A only)
• Disease progression during or following treatment with appropriate EGFR targeted therapy (cohort B only)
• Measurable disease per RECIST v1.1
• Biopsy post-progression on anti-PD(L)1 (cohort A) or EGFR targeted therapy (cohort B) confirming non-squamous histology prior to study treatment initiation
• ECOG Performance Status of 0-2
• Adequate hematologic and end-organ function, defined by the following laboratory test results, obtained within 14 days prior to initiation of study treatment:
• ANC ≥ 1.0 x 10\^9/L without granulocyte colony-stimulating factor support
• Lymphocyte count ≥ 0.5 x 10\^9/L
• Platelet count ≥ 100 x 10\^9/L without transfusion
• Hemoglobin ≥ 80 g/L (8 g/dL) - patients may be transfused to meet this criterion.
• AST, ALT, and alkaline phosphatase (ALP) ≤ 2.5 x upper limit of normal (ULN), with the following exceptions: Patients with documented liver metastases: AST and ALT ≤ 5 x ULN; Patients with documented liver or bone metastases: ALP ≤ 5 x ULN
• Serum bilirubin ≤ 1.5 x ULN with the following exception: Patients with known Gilbert disease: serum bilirubin ≤ 3 x ULN
• Creatinine clearance ≥ 30 mL/min (calculated using the Cockcroft-Gault formula)
• For patients not receiving therapeutic anticoagulation: INR and aPTT ≤ 1.5 x ULN
• For patients receiving therapeutic anticoagulation: stable anticoagulant regimen defined as clinical stability on unchanged dose of therapeutic anticoagulation for ≥14 days
• For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agreement to refrain from donating eggs, as defined below:
• Women must remain abstinent or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for 6 months after the final dose of study treatment. Women must refrain from donating eggs during this same period.
• A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements.

You may not qualify if…

• Prior treatment with anti-TIGIT antibody therapy
• Prior treatment with anti-PD(L)1 therapeutic antibodies for advanced NSCLC (cohort B only)
• Untreated or symptomatic CNS metastases
• History of leptomeningeal disease
• Active or history of clinically significant autoimmune disease that, in the opinion of the investigator, could compromise the health and safety of the patient if treated with investigational therapy. Notable exceptions include:
• Patients with a history of autoimmune-related hypothyroidism who are on thyroid-replacement hormone.
• Patients with controlled Type 1 diabetes mellitus who are on an insulin regimen.
• Active or history of adrenal insufficiency on stable steroid regimen.
• Patients with eczema, psoriasis, lichen simplex chronicus, or vitiligo with dermatologic manifestations only are eligible for the study provided all of following conditions are met: disease is well controlled at baseline and requires only low-potency topical corticosteroids; no occurrence of acute exacerbations of the underlying condition requiring psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents, oral calcineurin inhibitors, or high-potency oral corticosteroids within the previous 12 months
• History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted.
• Known active tuberculosis
• Current treatment with anti-viral therapy for HBV
• Positive EBV viral capsid antigen antibody (IgM) testing at screening. An EBV PCR test should be performed as clinically indicated to screen for acute infection or suspected chronic active infection. Patients with a positive EBV PCR test are excluded.
• Major surgical procedure, other than for diagnosis, within 4 weeks prior to initiation of study treatment, or anticipation of need for a major surgical procedure during the study
• History of malignancy other than NSCLC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death as assessed and confirmed by the study PI. Possible examples include: adequately treated carcinoma in situ of the cervix, non melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer
• Severe infection within 3 weeks prior to initiation of study treatment, including, but not limited to, hospitalization for complications of infection (including COVID-19), bacteremia, or severe pneumonia
• Prior allogeneic stem cell or solid organ transplantation
• Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that, in the view of the investigator, contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications
• Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study treatment, or anticipation of need for such a vaccine during study treatment or within 5 months after the final dose of study treatment
• Prior immune-related adverse event resulting in permanent discontinuation of immune checkpoint blockade therapy including but not limited to anti-PD-1, anti-PD-L1 and anti-CTLA4 therapeutic antibodies (cohort A only) that, in the view of the investigator, could compromise health and safety of prospective patient if enrolled in the study
• Inadequately controlled hypertension (defined as systolic blood pressure > 150 mmHg and/or diastolic blood pressure > 100 mmHg). Anti-hypertensive therapy to achieve these parameters is allowable
• Prior history of hypertensive crisis or hypertensive encephalopathy
• Significant vascular and cardiovascular disease (e.g., New York Heart Association Class II or greater heart failure, unstable arrhythmia, aortic aneurysm requiring surgical repair or recent peripheral arterial thrombosis - including but not limited to myocardial infarction, transient ischemic attack, stroke or unstable angina) within 6 months prior to study treatment initiation
• History of hemoptysis (≥ ½ teaspoon of bright red blood per episode) or clinically significant hemorrhage within 1 month of study treatment initiation
• Evidence of bleeding diathesis or significant coagulopathy (in absence of therapeutic anticoagulation)
