About this study

Official title: A Multicenter, Phase 2, Open-label Study of Intratumoral CMP-001 in Combination With Intravenous Pembrolizumab in Subjects With Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma

CMP-001-007 is a Phase 2 study of CMP-001 intratumoral (IT) and pembrolizumab intravenous (IV) administered to participants with head and neck squamous cell carcinoma (HNSCC) who have not been previously treated with a programmed cell death protein 1 (PD-1) blocking antibody.

The primary objective of the study is to determine the Investigator-assessed confirmed objective response with CMP-001 in combination with pembrolizumab in subjects with head and neck squamous cell carcinoma (HNSCC)

The secondary objectives are to:

  • To evaluate the safety and tolerability of CMP-001 administered by intratumoral (IT) injection in combination with pembrolizumab in subjects with HNSCC
  • To evaluate the efficacy of CMP-001 in combination with pembrolizumab in subjects with HNSCC
  • To evaluate the effect of human papillomavirus (HPV) infection and programmed death-ligand 1 (PD-L1) expressions on the efficacy of CMP-001 in combination with pembrolizumab

Participants will continue to receive treatment of CMP-001 and pembrolizumab according to the treatment schedule until a reason for treatment discontinuation is reached.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CMP-001 and Pembrolizumab in people with Squamous Cell Carcinoma of Head and Neck, run by Regeneron Pharmaceuticals at 19 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 15 inclusion and 26 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 11 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 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 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?

Yes. Results are posted in the registry (first posted 8 Apr 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) (time frame: Up to approximately 109 weeks). 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 11 May 2025.
