About this study

Official title: A Phase II Study of MK-3475 in Patients With Advanced Merkel Cell Carcinoma (MCC)

This phase II trial studies how well pembrolizumab works in treating patients with Merkel cell cancer that cannot be removed by surgery or controlled with treatment, or has spread to other parts of the body. Pembrolizumab may stimulate the immune system to identify and destroy cancer cells.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the clinical efficacy of MK-3475 (pembrolizumab) as the first systemic intervention for patients with advanced Merkel cell carcinoma (MCC).

SECONDARY OBJECTIVES:

  1. To determine the clinical activity of MK-3475 as the first systemic intervention for patients with advanced MCC.

TERTIARY OBJECTIVES:

  1. To determine the immune correlates of the clinical activity of MK-3475.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 24 months in the absence of disease progression* or unacceptable toxicity.

  • NOTE: Patients with confirmed disease progression may continue to receive treatment if they are otherwise clinically stable until there is an increase in tumor burden of 25% or more following initial confirmation of progression. Under exceptional circumstances, and with protocol principal investigator (P.I.) and Cancer Immunotherapy Trials Network (CITN) P.I. approval, patients may receive treatment beyond 2 years.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for 1 year, every 6 months for 2 years, annually until the patient has completed 3 years of follow up for disease assessment, and then every 12 weeks.

What is being measured

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

  1. Objective Response Rate (ORR) Defined as the Proportion of Patients Who Have Achieved Complete Response (CR) or Partial Response (PR) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    ORR will be estimated as the number of responders as a percent of the number of eligible participants who received at least one dose of treatment. If a substantial amount of data is missing, analyses will be performed using parametric generalized linear models fit by maximum likelihood. A generalized linear model for the ORR will use a binomial error distribution. The model will include as covariates all available baseline predictors of the missing outcomes. Responses to continued pembrolizumab will be chronicled and reported.

    Measured: Up to 3 years

Secondary outcomes (4)

  1. Progression-free Survival (PFS) Using RECIST 1.1

    Survival curves for PFS will be estimated using the Kaplan-Meier method. Assessed percentage of participants with progression free survival up to 16 months.

    Measured: Time from start of treatment to time of progression or death, whichever occurs first, assessed up to 16 months

  2. Duration of Response (DOR)

    Survival curves for DOR will be estimated using the Kaplan-Meier method.

    Measured: Time interval between the date of first response (CR/PR) and the date of progression, assessed up to 3 years

  3. Overall Survival (OS)

    Survival curves for OS will be estimated using the Kaplan-Meier method.

    Measured: Time interval between the start of treatment to death due to any cause, assessed up to 60 months.

  4. Incidence of Adverse Events (AEs) Graded Using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0

    Safety will be assessed by quantifying the toxicities and grades experienced by subjects including serious AEs (SAEs) and events of clinical interest. Safety and tolerability will be assessed by clinical review of all relevant parameters including AEs, laboratory tests, vital signs, and electrocardiogram measurements. Assessed number of participants who experienced grade 3 to 5 adverse events.

    Measured: Up to 90 days post-treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Laboratory Biomarker Analysis and Pembrolizumab in people with Recurrent Merkel Cell Carcinoma and Stage III Merkel Cell Carcinoma AJCC v7, run by National Cancer Institute (NCI) at 13 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 20 inclusion and 38 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: finished, as of the sponsor's last update on 5 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 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 1 Mar 2019). 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?

Objective Response Rate (ORR) Defined as the Proportion of Patients Who Have Achieved Complete Response (CR) or Partial Response (PR) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (time frame: Up to 3 years). 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 NCT02267603, which also lists 5 linked publications.

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 5 Jul 2023; AzTrials last refreshed its copy on 8 Nov 2026.
