Trial summary

This study is researching an experimental drug called REGN5093-M114 by itself and in combination with cemiplimab. The study is focused on advanced non-small cell lung cancer (NSCLC) that produces too much of a protein called mesenchymal epithelial transition factor (MET) on the cancer cell surface.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Histologically confirmed NSCLC that is at advanced stage for which there are no approved therapies available expected to confer clinical benefit as defined in the protocol
  • Willing to provide tumor tissue from newly obtained biopsy from tumor site. Newly obtained biopsies at tissue screening are required. An archival sample can be accepted only after discussion with the medical monitor and if the sample is not more than 6 months old and was obtained on the treatment regimen prior to study screening or after completion of the last therapy. The enrollment of patients will be based on an immunohistochemistry (IHC)-based assay using freshly obtained tumor biopsies or an archival biopsy as described above. Only patients with MET overexpressing tumors by central IHC analysis will be enrolled. For expansion cohorts only: tumor site for biopsy must not have been irradiated previously and must not be the only measurable lesion.
  • Tumor must overexpress MET protein as defined in the protocol
  • For expansion only: At least one lesion that is measurable by RECIST 1.1. Tumor lesions in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions after radiation.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Adequate organ and bone marrow function as defined in the protocol

Who cannot join

  • Has received treatment with an approved systemic therapy or has participated in any study of an investigational agent or investigational device within 2 weeks or 5 half-lives of the prior treatment, whichever is shorter with a minimum of 7 days from the first dose of study therapy
  • Has not yet recovered (ie, grade ≤1 or baseline) from any acute toxicities resulting from prior therapy except as described in the protocol
  • Has received radiation therapy or major surgery within 14 days of first administration of study drug or has not recovered from adverse events as defined in the protocol
  • Another malignancy that is progressing or requires active treatment except as noted in the protocol
  • Untreated or active primary brain tumor, central nervous system (CNS) metastases, leptomeningeal disease, or spinal cord compression as defined in the protocol
  • Encephalitis, meningitis, organic brain disease (eg Parkinson's disease) or uncontrolled seizures in the year prior to first dose of study therapy
  • Uncontrolled infection with human immunodeficiency virus (HIV), hepatitis B or hepatitis C infection; or diagnosis of immunodeficiency as defined in the protocol
  • NOTE: Other protocol-defined Inclusion/ Exclusion criteria apply

About this study

Official title: A Phase 1/2 Study of REGN5093-M114 (METxMET Antibody-Drug Conjugate) in Patients With MET Overexpressing Advanced Cancer

This study is researching an experimental drug called REGN5093-M114 by itself and in combination with cemiplimab. The study is focused on advanced non-small cell lung cancer (NSCLC) that produces too much of a protein called mesenchymal epithelial transition factor (MET) on the cancer cell surface. The aim of the study is to see how safe, tolerable, and effective the study drug is. This study will include 3 study groups, or cohorts, and each group is split into 2 parts:

Part 1: The main purpose of part 1 is to determine a safe dose of REGN5093-M114 (Cohorts A and B), and in combination with cemiplimab (Cohort C).

Read more

Part 2: The main purpose of part 2 is to use the REGN5093-M114 dose found for each cohort in part 1 to see how well the study drug works to shrink tumors.

The study is looking at several other research questions, including:

  • What side effects may happen from receiving the study drug
  • Does the study drug work to reduce or delay the progression of your cancer
  • How much study drug is in the blood at different times
  • Does the body make antibodies against the study drug (which could make the drug less effective or could lead to side effects)

The trial was intended to be a Phase 1/2 trial, but no participants were enrolled in Phase 2

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing REGN5093-M114 and Cemiplimab in people with Advanced NSCLC, run by Regeneron Pharmaceuticals at 11 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 6 inclusion and 8 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 3 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 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 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?

The study was stopped early (reason given: Sponsor decision). Results are not available in the source record.

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?

Dose limiting toxicities (DLTs) (time frame: Up to 28 days). The study lists 11 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 Nov 2025.
