About this study

Official title: A Randomized, Open-label, Active-control, Phase 2/3 Study of First-line Intratumoral CMP-001 in Combination With Intravenous Nivolumab Compared to Nivolumab Monotherapy in Subjects With Unresectable or Metastatic Melanoma

CMP-001-011 is a Phase 2/3 study of CMP-001 intratumoral (IT) and nivolumab intravenous (IV) compared to nivolumab monotherapy administered to participants with unresectable or metastatic melanoma.

The study is divided into two phases: Phase 2 and Phase 3.

The primary objective of Phase 2 of the study is to determine confirmed objective response rate (ORR) for treatment with first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma.

The secondary objective of Phase 2 of the study is to evaluate the safety and tolerability of first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma.

The primary objective of Phase 3 of the study is to evaluate progression-free survival (PFS) for subjects receiving first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy for unresectable or metastatic melanoma.

The secondary objectives of Phase 3 are to:

  • To evaluate the safety and tolerability of first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma.
  • To evaluate the efficacy of first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma.

    Measured: Up to approximately 39 months

  6. Duration of Response (DOR) by Investigator

    DOR, defined as time from the date of first documented response (CR or PR) to the date of documented progressive disease (PD), based on RECIST vl.1 by Investigator or death, whichever occurred first.

    Measured: Up to approximately 39 months

    PFS, defined as the time from the date of randomization to date of documented PD based on RECIST vl.1 by BICR or death, whichever occurred first.

    Measured: Up to approximately 39 months

  9. Progression-free Survival (PFS) by Investigator

    PFS, defined as the time from the date of randomization to date of documented PD based on RECIST vl.1 by Investigator or death, whichever occurred first.

    Measured: Up to approximately 39 months

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing CMP-001 and Nivolumab in people with Melanoma and Advanced Melanoma, run by Regeneron Pharmaceuticals at 20 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 27 inclusion and 28 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 15 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 20 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 5 Sep 2025). 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?

Confirmed Objective Response Rate (ORR) by Blinded Independent Central Review (BICR) (time frame: Up to approximately 39 months). 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 15 Jun 2026.
