What participants receive

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

  • Personalized cancer vaccine including : DNA neoantigen vaccine, MVA viral vector and Ipilimumab (anti-CTLA4)Biological

    Participants receive a combination therapy including DNA vaccine 4 mg IM, MVA 10⁷ pfu, and Ipilimumab IV at the dose assigned per arm: 2.5 mg, 5 mg, or 10 mg. Dose escalation is done sequentially in Phase I. The selected dose (RP2D) will be used in Phase II expansion.

What is being measured

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

  1. Phase 1 : Maximum Tolerated Dose (MTD) based on Dose Limiting Toxicity (DLT) (28 days) of ODI-2001 Phase 2 : Progression-Free Survival (PFS)

    Phase 1 : The maximum tolerated Dose (MTD) is defined as the highest dose level of ipilimumab in comination with the ODI-2001 vaccine at which no more than 1 out of 6 patients experiences a dose Limiting Toxicities (DLT). DLT are assessed according to NCI-CTCAE (National Cancer Institute Common Terminology Criteria for Adverse Events) version 5.0 and include predefined hematologic and non-hematologic toxicities considerad related to ODI-2001 administration. If ≥ 2 patients in a cohort of up to 6 patients experience a DLT, the dose is considered above the MTD.

    Phase 2 : Progression-Free Survival (PFS) is defined as the time from the start of first-line chemotherapy to the first documented disease progression according to RECIST version 1.1 or death from any cause, whichever occurs first. PFS will be estimated using the Kaplan-Meier method.

    Measured: Phase 1 : within 28 days following the first administration of ODI-2001 Phase 2 : Up to 14 months for colorectal cancer cohort and up to 10 months for pancreatic cancer cohort following initiation of chemotherapy.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Personalized cancer vaccine including : DNA neoantigen vaccine, MVA viral vector and Ipilimumab (anti-CTLA4) in people with Metastatic Colorectal Cancer (CRC) and Locally Advanced Colorectal Cancer, run by Centre Georges Francois Leclerc at 2 sites in France.

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 20 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: opening soon, as of the sponsor's last update on 14 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. 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 François FG GHIRINGHELLI, Pr (03 45 34 75 38 ext. +33, fghiringhelli@cgfl.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1 : Maximum Tolerated Dose (MTD) based on Dose Limiting Toxicity (DLT) (28 days) of ODI-2001 Phase 2 : Progression-Free Survival (PFS) (time frame: Phase 1 : within 28 days following the first administration of ODI-2001 Phase 2 : Up to 14 months for colorectal cancer cohort and up to 10 months for pancreatic cancer cohort following initiation of chemotherapy.). 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 14 May 2026.
