What is being measured

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

  1. Dose Limiting Toxicities in Phase I participants

    Phase I participants will be evaluated for dose limiting toxicities (DLTs) during the first 14 day cycle and 14 days post-operatively for the purpose of determining the recommended phase II dose of AGEN2373 when given concurrently with balstilimab and cancer vaccination.

    Measured: 1 month

  2. Number of participants experiencing Grade 3 or Higher study drug-related toxicities

    Number of participants experiencing study drug-related adverse events Grade 3 or higher as defined by CTCAE v5.0

    Measured: 2 years

  3. Number of participants who form Intratumoral tertiary lymphoid structures (TLS)

    Number of participants who form at least one tertiary lymphoid structure (TLS) following one cycle of study drugs. The presence of at least 50 CD20+ B cells and 50 CD3+ T cells in a ≥50 µM area of surgical tissue is considered "positive" for TLS.

    Measured: 2 weeks

Secondary outcomes (3)
  1. Pathologic overall response rate (pORR)

    Number of participants who have a pathologic response to the first dose of study drug as determined using surgically resected tissue and the College of American Pathologists (CAP) scoring system. A pathologic response is defined as CAP grade of 0-2. Possible CAP grades include grade 0: Complete Response/ No viable residual tumor; grade 1: Marked Response/ minimal residual cancer with single cells or small groups of cancer cells; grade 2: Moderate Response/ residual cancer outgrown by fibrosis; and grade 3: Poor or No response/ extensive residual cancer.

    Measured: evaluated at time of surgery, approximately 2 weeks from first dose of study drug

  2. CD3+CD8+CD137+ T cell density in Tumor Tissue

    Number of CD3+CD8+CD137+ T cells found in resected surgical tissue by Immunohistochemistry (IHC).

    Measured: evaluated at time of surgery, approximately 2 weeks from first dose of study drug

  3. Change in peripheral interferon-gamma (IFNγ) producing mutant KRAS-specific T cells

    Percent change in the number of IFNγ producing T cells at Cycle 2 Day 14 when compared with baseline. Number of IFNγ T cells will be assessed by ELISPOT.

    Measured: 13 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing AGEN2373, Balstilimab and Cyclophosphamide in people with Pancreatic Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins 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 7 inclusion and 16 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 3 Dec 2025. 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 combined 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.

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?

Contact Colleen Apostol, RN (410-614-3644, GIClinicalTrials@jhmi.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose Limiting Toxicities in Phase I participants (time frame: 1 month). The study lists 3 primary outcomes in all. 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 3 Dec 2025.
