  • Screening Period: approximately 28 days
  • Treatment Period: up to 24 months, or until any criterion for stopping the study drug or withdrawal from the study occurs
  • Follow-up Period: up to 24 months from last dose of study treatment for every patient who is alive

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Botensilimab + BalstilimabDrug

    Also called AGEN1181 + AGEN2034

    Botensilimab is a fragment crystallizable (Fc)-engineered human immunoglobulin G1 (IgG1) monoclonal antibody that targets cytotoxic T lymphocyte-associated protein 4 (CTLA-4). Balstilimab is a human monoclonal antibody that targets programmed cell death protein 1 (PD-1).

What is being measured

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

  1. 12-Month Progression-Free Survival (PFS)

    12-Month PFS is defined as the proportion of patients who remain alive and progression-free at 12 months from the first dose of investigational drug, where tumor progression is documented per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) and modified Response Evaluation Criteria in Solid Tumors version 1.1 for immune-based therapeutics (iRECIST) as assessed by investigator.

    Measured: First dose to up to 12 months

Secondary outcomes (14)

  1. Objective Response Rate (ORR)

    ORR is defined as the proportion of subjects with a complete response (CR) or partial response (PR) per RECIST v1.1 and iRECIST, as assessed by investigator.

    Measured: First dose to up to 6 months

  2. Disease Control Rate (DCR)

    DCR is defined as the percentage of patients who have achieved complete response, partial response or stable disease per the RECIST v1.1 and iRECIST criteria.

    Measured: First dose to up to 6 months

  3. Duration of Response (DOR)

    DOR is defined as the time from initial objective radiographic response per RECIST v1.1 and iRECIST as assessed by investigator until the first documentation of progression or death, whichever occurs first.

    Measured: First dose to up to 48 months

  4. Time to Next Treatment (TTNT)

    TTNT is defined as the time from the first dose of investigational drug to the start date of a subsequent line of therapy.

    Measured: First dose to up to 48 months

  5. Overall Survival (OS) Time

    OS Time is defined as the time from the first dose of investigational drug until death to any cause.

    Measured: First dose to up to 48 months

  6. Frequency, severity, and duration of treatment emergent adverse events (TEAEs) (Safety and tolerability)

    Adverse events (AEs) according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0 (NCI CTCAE v5.0), serious adverse events, AEs leading to treatment discontinuation or death.

    Measured: First dose to up to 27 months

  7. Health-related quality of life (HRQoL) according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)

    HRQoL is a patient-reported outcome (PRO) assessed using EORTC QLQ-C30.

    Measured: First dose to up to 25 months

  8. Health-related quality of life according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer (EORTC QLQ-LC29)

    Patient-reported outcome assessed using EQ-5D-5L

    Measured: First dose to up to 25 months

  10. Correlation between baseline expression of PD-L1 by immunohistochemistry (IHC) and 12-month progression-free survival

    PD-L1 expression at baseline will be assessed via immunohistochemistry and categorized into negative (<1%), low expression (1-49%), and high expression (>50%), and its correlation with 12-month progression-free survival will be investigated.

    Measured: First dose to up to 24 months

  11. Correlation between baseline expression of PD-L1 by immunohistochemistry (IHC) and objective response rate

    PD-L1 expression at baseline will be assessed via immunohistochemistry and categorized into negative (<1%), low expression (1-49%), and high expression (>50%), and its correlation with objective response rate will be investigated.

    Measured: First dose to up to 24 months

  12. Correlation between existence of liver metastases on imaging at baseline and 12-month progression-free survival

    Presence of liver metastases at baseline will be assessed via imaging and its correlation with 12-month progression-free survival will be investigated.

    Measured: First dose to up to 24 months

  13. Correlation between existence of liver metastases on imaging at baseline and objective response rate

    Presence of liver metastases at baseline will be assessed via imaging and its correlation with objective response rate will be investigated.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Botensilimab + Balstilimab in people with Non-small Cell Lung Cancer, run by Immune Oncology Research Institute at 1 site in Armenia.

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 21 inclusion and 24 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: under way, not looking for participants, as of the sponsor's last update on 8 Jun 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 Armenia. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

12-Month Progression-Free Survival (PFS) (time frame: First dose to up to 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06322108.

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 8 Jun 2026.
