About this study

Official title: A Phase Ib Trial of PBF-1129 and Nivolumab in Patients With Advanced Non-Small Cell Lung Cancer

This phase I trial studies the side effects and best dose of PBF-1129 in combination with nivolumab in treating patients with non-small cell lung cancer that has come back (recurrent) or spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as PBF-1129 and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the safety and tolerability of the combination of adenosine A2B receptor antagonist PBF-1129 (PBF-1129) and nivolumab in patients with advanced non-small cell lung cancer (NSCLC) based upon the Common Terminology Criteria for Adverse Events (CTCAE) version 5 criteria.

SECONDARY OBJECTIVE:

  1. To determine the efficacy of the combination of PBF-1129 and nivolumab in patients with advanced NSCLC, including progression-free survival (PFS), objective response (ORR), disease control rate (DCR), and overall survival (OS) based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

EXPLORATORY OBJECTIVES:

  1. To study the effect of PBF-1129 on the levels of myeloid-derived suppressor cells (MDSC) within the tumor microenvironment (TME) and in peripheral blood of study patients.

II. To evaluate correlative biomarkers that might predict disease response to treatment with PBF-1129 and nivolumab therapy in previously treated NSCLC patients including STK11 genetic alterations and a transcriptional signature of LKB1 functional status developed by the Carbone lab.

OUTLINE: This is a dose-escalation study of PBF-1129 given in combination with immune checkpoint blockade.

Patients receive adenosine A2B receptor antagonist PBF-1129 (PBF-1129) orally (PO) once daily (QD) and nivolumab intravenously (IV) on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 12 weeks for up to 1 year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of adverse events

    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.

    Measured: Up to 30 days after the last dose of study treatment

Secondary outcomes (4)
  1. Overall objective response rate

    Will be calculated and exact binomial 95% confidence interval (CI) will be provided.

    Measured: Up to 1 year after treatment discontinuation

  2. Disease control rate

    Will be calculated and exact binomial 95% CI will be provided.

    Measured: Up to 1 year after treatment discontinuation

  3. Overall survival

    Will be defined as time from initiation of therapy to death, or censored at last follow-up date if the subject is alive. Kaplan-Meier methods will be used to estimate overall survival with 95% CI.

    Measured: Up to 1 year after treatment discontinuation

  4. Progression free survival

    Will be defined as the time from initiation of therapy to the time of Response Evaluation Criteria in Solid Tumors progression or death. Kaplan-Meier methods will be used to estimate progression free survival with 95% CI.

    Measured: Up to 1 year after treatment discontinuation

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Adenosine A2B Receptor Antagonist PBF-1129, Biospecimen Collection and Nivolumab in people with Metastatic Lung Non-Small Cell Carcinoma and Recurrent Lung Non-Small Cell Carcinoma, run by Dwight Owen at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 6 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact The Ohio State University Comprehensive Cancer Center (800-293-5066, OSUCCCClinicaltrials@osumc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of adverse events (time frame: Up to 30 days after the last dose of study treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2026.
