PBF-1129 and Nivolumab for Recurrent or Metastatic Non-Small Cell Lung Cancer
This study is testing a combination of two drugs, PBF-1129 and nivolumab, for people with non-small cell lung cancer that has returned or spread. PBF-1129 is an adenosine A2B receptor antagonist, and nivolumab is an immunotherapy drug. Both aim to help your body's immune system fight cancer. The main goal is to see how safe this combination is and what side effects it might cause. Researchers also want to see how well the treatment works to control the cancer. You may be eligible if you are at least 18 years old, have measurable cancer, and have already received standard chemotherapy and immunotherapy, including prior PD-1 and/or PD-L1 directed therapies. The study plans to enroll 30 participants, but its current recruitment status is unclear.
- Study design
- This is a dose-escalation study, meaning participants will receive increasing doses of PBF-1129 in combination with nivolumab. It plans to enroll 30 participants.
- What's involved
- Participants will receive PBF-1129 by mouth once daily and nivolumab through an IV on day 1. Biospecimen collection will also be performed for correlative studies.
- Compensation
- Not stated in the trial record.
- Follow-up
- Adverse events will be measured for up to 30 days after the last dose of study treatment.

Eligibility criteria
Inclusion
Age \>= 18 years
Confirmed recurrent or metastatic non-small cell carcinoma of the lung of any histology without curative options
Measurable disease based on RECIST 1.1
Patients must have received standard of care chemotherapy and immunotherapy. No limits to prior lines of therapy. Prior PD-1 and/or PD-L1 directed therapies are required. Prior CTLA4 therapy is permitted. Patients may have received no more than 3 prior lines of therapy in the metastatic setting (excluding targeted therapies)
Patients with known actionable mutations with Food and Drug Administration (FDA)-approved treatment options must have received all approved and standard of care treatment options (ie osimertinib for EGFR, alectinib for ALK, etc)
Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
Absolute neutrophil count (ANC) \>= 1,500 /mcL
Platelets \>= 100,000 / mcL
Serum creatinine OR measured or calculated creatinine clearance (glomerular filtration rate \[GFR\] can also be used in place of creatinine or creatinine clearance \[CrCl\]) =\< 1.5 X upper limit of normal (ULN) OR \>= 60 mL/min for subject with creatinine levels \> 1.5 X institutional ULN
Serum total bilirubin =\< 1.5 X ULN OR direct bilirubin =\< ULN for subjects with total bilirubin levels \> 1.5 ULN
AAspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 3 X ULN OR =\< 5 X ULN for subjects with liver metastases
Albumin \>= 2.5 mg/dL
International normalized ratio (INR) or prothrombin time (PT) or activated partial thromboplastin time (aPTT) =\< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants =\< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
Anticipated life expectancy of \>= 3 months
Willing to comply with study procedures
Must be able to swallow pills
Female subjects of childbearing potential must be willing to use an adequate method of contraception
For female patients of childbearing potential, a negative serum pregnancy test within 7 days prior to first dose of protocol therapy is required
Be willing and able to understand and sign the written informed consent document
Availability of a recent formalin-fixed, paraffin-embedded (FFPE) tumor tissue block. A recently obtained archival FFPE tumor tissue block (if an FFPE tissue block cannot be provided, 15 unstained slides (10 minimum) will be acceptable) from a primary or metastatic tumor resection or biopsy can be provided if it was obtained within 1 year of trial screening. Patients with archival tissue that does not meet this criteria may still be eligible in the dose escalation cohort only upon approval from PI.
For patients in dose expansion cohort: Be willing to provide tissue from a pre-treatment and on-treatment fin needle aspirate (FNA) or core biopsy of a tumor lesion. Subjects must consent to pre-treatment and on-treatment biopsy prior to initiation of clinical trial, however subjects for whom newly-obtained samples cannot be provided (e.g. inaccessible or subject safety concern) may still continue on study
Be willing to provide peripheral blood samples for correlative studies
Exclusion
Has active autoimmune disease, including myasthenic syndrome, which has required systemic treatment in the past 12 months (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Patients with eczema, psoriasis, lichen simplex chronicus, or vitiligo with dermatologic manifestations only (e.g., patients with psoriatic arthritis are excluded) are eligible for the study provided that disease is well controlled at baseline and requires only topical corticosteroids.
Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (at a dose \> 10 mg prednisone or equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment

RR is the time from the interval of 1 QRS complex to the next measured in seconds and is commonly calculated as (60/heart rate \[HR\])

NOTE: Patients with a prior endocrine AE are permitted to enroll if they are stably maintained on appropriate replacement therapy and are asymptomatic
What this trial measures
- Incidence of adverse eventsUp to 30 days after the last dose of study treatment
Safety will be measured by the occurrence of dose-limited toxicities as well as any other adverse events as defined in Common Terminology Criteria for Adverse Events version 5. Frequency and severity of adverse events and tolerability of the regimen will be collected and summarized by descriptive statistics. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns. All patients who have received at least one dose of the therapeutic agents will be evaluable for toxicity and tolerability.
