About this study

Official title: A Pilot Study of Pembrolizumab Monotherapy in Patients With Previously Treated Advanced Gastroesophageal Adenocarcinoma

This early phase I trial studies how well pembrolizumab works in treating patients with gastroesophageal adenocarcinoma that has spread to other places or cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To estimate the overall response rate (ORR) of intravenous administration of pembrolizumab by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 in adult subjects with advanced (unresectable and/or metastatic) and previously treated gastroesophageal adenocarcinoma.

SECONDARY OBJECTIVES:

  1. To evaluate the duration of response (DOR), disease control rate (DCR), time to progression (TTP), progression-free survival (PFS), and overall survival (OS) using RECIST 1.1 and immune-related (ir)RECIST criteria.

II. To perform exploratory biomarkers to study the correlation between immunological and molecular changes in tumor tissues and peripheral blood with clinical outcomes (DOR, DCR, TTP, PFS, and OS) using RECIST 1.1, and irRECIST rate of adverse events.

III. To determine the safety and tolerability of intravenous administration of pembrolizumab or pembrolizumab plus ramucirumab in adult subjects with advanced (unresectable and/or metastatic) and previously treated gastroesophageal adenocarcinoma.

EXPLORATORY OBJECTIVES:

  1. To explore the association between PD-L1 expression by immunohistochemistry, shed PD-L1 levels, somatic gene expression profiling and antitumor efficacy of pembrolizumab based on RECIST 1.1 imaging criteria as well as overall survival.

II. To explore the relationship between genomic variation and response to the treatment administered.

III. Tissue and blood immune monitoring will be conducted through our immune platform group as detailed per the biomarker section based on 3 biopsies done at the following time points: 1) pre-treatment, 2) 6 weeks after therapy, and 3) and an optional biopsy upon progression.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 35 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 12 weeks thereafter.

    Measured: From first documented evidence of CR or PR up to 4 years

  2. Disease control rate

    Defined as the percentage of subjects who have achieved CR, PR, or stable disease (SD) for at least 24 weeks based on assessments by MD Anderson radiology per RECIST 1.1. Exact method based on binomial distribution (Clopper-Pearson method).

    Measured: Up to 4 years

  3. Time to progression

    Assessed per RECIST 1.1 based on assessments by MD Anderson radiology. Summary statistics using Kaplan-Meier method.

    Measured: From the first day of study treatment up to 4 years

  4. Progression-free survival per RECIST 1.1 based on assessments by MD Anderson radiology

    Summary statistics using Kaplan-Meier method.

    Measured: From the first day of study treatment to the first documented disease progression up to 4 years

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Pembrolizumab in people with Advanced Gastroesophageal Junction Adenocarcinoma and Clinical Stage III Esophageal Adenocarcinoma AJCC v8, run by M.D. Anderson Cancer Center at 1 site 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 19 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: finished, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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) (time frame: Up to 4 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 NCT03395847.

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 18 Nov 2023.
