About this study

Official title: A Phase II Study of Perioperative mFOLFOX (Fluorouracil, Leucovorin, and Oxaliplatin) Chemotherapy Plus Pembrolizumab(MK-3475) Combination in Patients With Potentially Resectable Adenocarcinoma of the Gastroesophageal Junction (GEJ) and Stomach (MISP #52216)

To evaluate the antitumor activity and safety/tolerability of the combination (mFOLFOX + Pembrolizumab) in patients with potentially resectable adenocarcinoma of the Gastroesophageal Junction (GEJ) and stomach.

Read the detailed description

This study will evaluate the efficacy and safety of perioperative mFOLFOX plus Pembrolizumab combination regimen in participants with potentially resectable adenocarcinoma of the GEJ and stomach.

  • The study is a non-randomized, open-label, single-arm phase II study.
  • The enrolled participants will receive neoadjuvant combination of mFOLFOX every 2 weeks for 4 doses (on Days 1, 15, 29, 43) and Pembrolizumab every 3 weeks for 3 doses (on Days 1, 22, 43).
  • Serious adverse events (SAEs) will be assessed on an ongoing basis using CTCAE v4.0, and the Thall, Simon, and Estey's design to monitor the efficacy and toxicity continuously together.
  • Repeat PET-CT will be obtained approximately 2-3 weeks after completion of neoadjuvant combination therapy.
  • If no evidence of metastatic disease on PET-CT, participants will undergo potentially curative surgical resection 4-6 weeks after completion of neoadjuvant combination therapy. This will be followed by adjuvant combination therapy (to be started 6-8 weeks after surgery) consisting of mFOLFOX every 2 weeks for additional 4 doses (total 4 months of therapy) plus Pembrolizumab every 3 weeks for additional 12 doses (total 1 year of therapy). If there is evidence of metastatic disease on PET-CT, participant will come off the study (i.e., will not undergo surgical resection and adjuvant therapy).
  • Participants will continue to receive treatment until either one of the following occurs: completion of adjuvant therapy, development of radiographically confirmed progression, participant withdraws consent, intercurrent illness that prevents further administration of treatment, or sponsor-investigator decides to withdraw the participant.
  • Efficacy outcomes during the adjuvant chemotherapy phase will be determined by radiologic measurements by CT using RECIST v1.1. Assessment of response will be performed every 3 months for the first year and as per the standard institutional guidelines thereafter.

What is being measured

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

  1. Pathological response rate (ypRR)

    Number of participants with ypRR after neoadjuvant therapy. Will be assessed on the surgical resection specimen after neoadjuvant therapy, using Haemotoxylin and Eosin (H\&E) staining and evaluated using Tumor Regression Score.

    Measured: 10-14 weeks

  2. Number of Adverse Events related to toxicity.

    Number of participants with adverse events related to toxicity. Evaluated using Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Participants will be followed for adverse event monitoring through the final safety follow up visit or until study discontinuation/disease progression, whichever occurs first.

    Measured: up to 14 months

Secondary outcomes (5)

  1. Objective response rate (ORR)

    Number of participants with ORR (partial response and complete response) at 12 months. Evaluated using RECIST v1.1

    Measured: 12 months

  2. Disease Free Survivial (DFS)

    Number of participants with DFS. Evaluated using computed tomography (CT).

    Measured: 12 months

  3. Overall Survival (OS)

    Number of participants with OS.

    Measured: 12 months

  4. PET response rate after completion of neo-adjuvant therapy.

    Evaluated using Positron emission tomography scan \& computed tomography (PET-CT)

    Measured: 10 weeks

  5. Programmed cell death ligand 1 (PD-L1) expression in tumor cells

    Change in PD-L1 expression on the surface and in the nucleus of the tumor cells over treatment will be related to complete pathological response (ypCR) by means of logistic regression. Evaluated by immunohistochemistry (IHC). Participants will be evaluated at baseline and reevaluated 2-4 weeks after surgery (for those participants who develop complications from surgery, the revaluation time frame may be extended to 7 weeks).

    Measured: baseline and between 16-21 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Neoadjuvant Treatment - mFOLFOX6 & Pembrolizumab and Adjuvant Treatment - mFOLFOX & Pembrolizumab in people with Gastro Esophageal Junction Cancer and Stomach Cancer, run by University of Kansas Medical 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 18 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: under way, not looking for participants, as of the sponsor's last update on 19 May 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?

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?

This study is still under way. Results are not available in the source record yet.

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?

Pathological response rate (ypRR) (time frame: 10-14 weeks). The study lists 2 primary outcomes in all. 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 NCT03488667, which also lists 1 linked publication.

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 19 May 2023.
