About this study

Official title: The Seena Magowitz Phase IB/II Trial of CMP-001 (a TLR9 Agonist) in Combination With INCAGN01949 (an Activating Anti-OX40 Antibody) for In Situ Intratumoral Injection for Patients With Stage IV Pancreatic and Other Cancers Except Melanoma

This phase Ib/II trial studies the side effects and best dose of CMP-001 and how well it works when given together with INCAGN01949 in treating patients with stage IV pancreatic cancer and other cancers except melanoma. CMP-001 is made up of a short piece of DNA that is packaged in a protein, known as a virus-like particle (VLP). VLPs are detected and processed by cells of the immune system. The DNA contained in CMP-001 activates the immune system and recruit cells of the immune system to the tumor. INCAGN01949 is an antibody, a type of protein, which has been shown to stimulate the immune system. Injecting CMP-001 and INCAGN01949 directly into the tumor may work against tumor cells to slow tumor growth by causing tumor cells to die.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the maximum tolerated dose and tolerance of virus-like particle VLP-encapsulated TLR9 agonist CMP-001 (CMP-001 [TLR9 agonist]) in combination with agonistic anti-OX40 monoclonal antibody INCAGN01949 (INCAGN01949) (an activating antibody against OX40) both given intratumorally for patients with previously treated (for their metastatic disease) pancreatic ductal adenocarcinoma and other types of cancer except melanoma. (Phase IB) II. To determine the efficacy (disease control rate of complete response [CR] + partial response [PR] + stable disease [SD] X 16 weeks) of CMP001 (TLR9 agonist) in combination with INCAGN01949 (anti-OX40 antibody) for patients with previously treated (for their metastatic disease) pancreatic ductal adenocarcinoma. (Phase II) III. To determine effects on tumor markers. (Phase II)

SECONDARY OBJECTIVES:

  1. Define the toxicity of the combination of CMP-001 (TLR9) + INCAGN01949 (OX40).

II. Determine progression free survival and overall survival.

EXPLORATORY OBJECTIVES:

  1. Using flow cytometry on peripheral blood OX40 expression will be analyzed within the lymphocyte subsets (effector T cell [Teff] and regulatory T cell [Treg]).

II. On tissue samples collected prior to, and during, treatment, will:

IIa. Use flow cytometry to enumerate CD4+ and CD8+ T cell subsets, and the expression of activation/differentiation markers (including CD127, HLA-DR, CD45RO, CCR7, CXCR3) on each.

IIb. Use reverse transcriptase-polymerase chain reaction (RT-PCR) and sequencing to amplify and characterize the T-cell receptor (TCR)a and b sequences of tumor-infiltrating T cells, looking for evidence of oligoclonal T cell expansion, OX40 expression.

IIc. If there is adequate tumor tissue, perform ribonucleic acid sequencing (RNAseq) to determine different immune cell populations, including T cells and macrophages.

OUTLINE: This is a phase Ib, dose-escalation study of INCAGN01949, followed by a phase II study.

Patients receive CMP-001 subcutaneously (SC) on day 1 of weeks 1 and 2 and intratumorally (IT) on day 1 of weeks 3-6 in the absence of disease progression or unacceptable toxicity. Patients also receive INCAGN01949 IT on day 1 of weeks 3-6 in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days, and then every 12 weeks.

What is being measured

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

  1. Disease Control Rate

    Defined as the best response recorded from the start of treatment until disease progression/recurrence, evaluated according to Response Evaluation Criteria In Solid Tumors Criteria (RECIST) v1.1 for target lesions and assessed by MRI: Complete Response (CR) = Disappearance of all target lesions; Partial Response (PR) = at least a 30% decrease in the sum of the diameters of the target lesions compared to the baseline; Stable Disease = Neither enough shrinkage for PR nor enough growth for PD; Progressive Disease = at least a 20% increase in the sum of the diameters of the target lesions from the smallest measurement recorded, with an absolute increase of at least 5 mm, or the appearance of one or more new lesions. All proportions will be estimated using an exact 95% binomial confidence interval.

    Measured: Through end of treatment, up to 2 months

  2. Objective Response Rate (CR + PR)

    Will be evaluated using the RECIST 1.1 and iRECIST. Changes (i.e. improvements) in tumor measurements from baseline values will be assigned a status of complete response (CR) or partial response (PR) or stable disease (SD). Objective response measurements will comprise the sum of CR plus PR.

    Measured: Through end of treatment, up to 2 months.

Secondary outcomes (3)

  1. Incidence of Adverse Events

    All adverse events occurring on or after week 1/day 1 will be summarized by body systems and per grade according to National Cancer Institute (NCI)-Common Terminology Criteria (CTC) version 5.

    Measured: Through study completion, up to 9 months

  2. Progression Free Survival (PFS)

    PFS is defined as the interval from the date of registration (i.e. assignment of patient number) to the earliest date of documented evidence of recurrent or progressive disease, or the date of death due to any cause, whichever occurs first. All proportions will be estimated using an exact 95% binomial confidence interval, and a Kaplan-Meier analysis will be performed.

    Measured: Through study completion, up to 9 months

  3. Overall Survival

    Will be measured from the date of registration (i.e. assignment of patient number) to the date of death due to any cause, or the date of last contact (censored observations). All proportions will be estimated using an exact 95% binomial confidence interval, and a Kaplan-Meier analysis will be performed.

    Measured: Through study completion, up to 9 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Agonistic Anti-OX40 Monoclonal Antibody INCAGN01949 and VLP-encapsulated TLR9 Agonist CMP-001 in people with Locally Advanced Malignant Solid Neoplasm and Metastatic Pancreatic Adenocarcinoma, run by University of Southern California at 4 sites 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 28 inclusion and 21 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: stopped early, as of the sponsor's last update on 17 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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?

Yes. Results are posted in the registry (first posted 17 Feb 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Disease Control Rate (time frame: Through end of treatment, up to 2 months). The study lists 2 primary outcomes in all. 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 NCT04387071.

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 17 Apr 2026.
