Brief summary

The goal of this clinical trial is to: 1) evaluate the safety and recommended dose of the drug OT-101/Trabedersen when combined with Pembrolizumab and 2) determine the efficacy of the combination therapy in adults with certain types of Non-Small Cell Lung Cancer. The main question(s) it aims to answer are: * What medical problems to participants have when taking OT101 together with Pembrolizumab? * What is the correct dose of OT-101 to use when evaluating the safety and efficacy of the combination therapy? * Does the combination therapy delay progression or relapse of the participant's Non-Small Cell Lung Cancer? Participants will: * Receive intravenous OT-101/Trabedersen for 4 days once every 2 weeks. Clinic visits are required to receive and disconnect the infusion. * Receive intravenous Pembrolizumab once every 6 weeks.

The goal of this clinical trial is to: 1) evaluate the safety and recommended dose of the drug OT-101/Trabedersen when combined with Pembrolizumab and 2) determine the efficacy of the combination therapy in adults with certain types of Non-Small Cell Lung Cancer. The main question(s) it aims to answer are: * What medical problems to participants have when taking OT101 together with Pembrolizumab? * What is the correct dose of OT-101 to use when evaluating the safety and efficacy of the combination therapy? * Does the combination therapy delay progression or relapse of the participants Non-Small Cell Lung Cancer? Participants will: * Receive intravenous OT-101/Trabedersen for 4 days once every 2 weeks. Clinic visits are required to receive and disconnect the infusion. * Receive intravenous Pembrolizumab once every 6 weeks. In Phase I, dose escalation/de-escalation of OT101/Trabedersen is performed using a BOIN design to determine dose limiting toxicity (DLT) and the recommended phase 2 dose (RP2D) when combined with Pembrolizumab. In Phase II, subjects receive the RP2D of OT101/Trabedersen together with Pembrolizumab until disease relapse, progression \[as determined by immune Response Evaluation Criteria in Solid Tumours (iRECIST) criteria\], or death.

Interventions

Trabedersen (OT-101) is a synthetic antisense oligodeoxynucleotide that specifically inhibits the production of Transforming growth factor-beta 2 (TGF-β2).

DRUGPembrolizumab

Pembrolizumab is a humanized anti-programmed death (PD-1) monoclonal antibody.

Intervention model description

Participants are enrolled into the Phase I arm until the recommended phase 2 dose (RP2D) is determined. Participants who receive the RP2D in Phase I are reassigned to the Phase II arm.

Inclusion criteria

* Age ≥ 19 years * Histologically/cytologically proven diagnosis of non-small cell lung cancer (NSCLC) with a PD-L1 of at least 1% * Metastatic disease or disease not amenable for curative intent therapy * No prior treatment for metastatic NSCLC. Early-stage disease therapy acceptable if completed at least six months prior and did not include immunotherapy. * Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 * Measurable disease by RECIST criteria * Adequate organ and marrow function as defined below: * Absolute neutrophil count ≥1,500/mm3 * Platelets ≥100,000/mm3 * Hemoglobin \>9.0 mg/dL * Creatinine clearance \> 60 ml/min/1.73 m2 using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula * Total serum bilirubin \<1.5 X upper limit of normal (ULN) except if known to have Gilbert's syndrome, then excluded if total bilirubin \>2.5 X ULN * Aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT)/serum glutamic-pyruvic transaminase (SGPT) ≤ 2.5 x ULN; if participant has liver metastases, ≤5x ULN * For females of childbearing potential, negative serum or urine pregnancy test ≤7 days of treatment, & agree to use effective contraceptive during treatment & 90 days after end of treatment * Male participants must agree to use effective contraception during the trial & for 90 days after end of treatment * Able to give informed consent

Exclusion criteria

* Received any systemic treatments including investigational agents within the last 28 days * Known hypersensitivity to any of the excipients of OT101 or pembrolizumab * Received radiotherapy within 14 days of the study intervention. Palliative radiation is allowed during the study with a 1-week washout * Pregnant or breast-feeding women * History of autoimmune diseases that required systemic treatment in the past 2 years with agents such as, but not limited to, corticosteroids or immunosuppressive drugs. Thyroid replacement for hypothyroidism, insulin treatment for type I diabetes or corticosteroids adrenal/pituitary insufficiency are allowed. * Uncontrolled systemic diseases that in the opinion of the investigator may interfere with the protocol activities * Known active second malignancy that needs treatment. Exceptions include basal cell or squamous cancers of the skin, bladder or cervical carcinoma in situ, prostate cancer on hormone therapy alone. * Immunodeficiency diagnosis or receiving chronic steroids that exceed a dose equivalent to prednisone 10 mg daily * Symptomatic brain metastases. Asymptomatic metastases or having received treatment for brain metastases and are off steroid therapy is acceptable. * Known psychiatric or substance use that would interfere with the study requirements * Inability to co-operate with the requirements of the protocol
