About this study

Official title: A Phase I/II Study of Personalized Immunotherapy in Adults With Upper Gastrointestinal Tract Cancers

The purpose of this study is to determine if it is possible to make and safely administer a 'personalized' cancer vaccine for people diagnosed with an upper gastrointestinal tract cancer.

Read the detailed description

The purpose of this study is to determine if it is possible to make and safely administer a 'personalized' cancer vaccine for people diagnosed with an upper gastrointestinal tract cancer.

It is known that cancer has mutations (changes in genetic material) that are specific to an individual person and their tumor. These mutations can cause the tumor cells to produce proteins that are different from the body's normal, healthy cells. The study will use a sample of your tumor to create a vaccine against it, with the idea being that the study vaccine will "teach" the body's immune system to recognize and attack the cancer cells. The study will examine the safety of the study vaccine when given at several time points and will examine your blood for signs that the study vaccine causes the immune system to respond.

The personalized cancer vaccine will be given alone or in combination with nivolumab. Nivolumab is a drug that blocks certain proteins on cells that help to keep immune responses in check. In a healthy person, this keeps the immune system from attacking healthy cells and tissues, but cancer cells use these proteins to keep the immune system from killing cancer cells and tumors. When these proteins are blocked, the check on the immune system is removed and immune cells may be able to recognize and kill cancer cells.

This personalized cancer vaccine is considered experimental because it is not approved by the US Food \& Drug Administration (FDA) as a treatment for cancer.

The combination of nivolumab and the personalized cancer vaccine is experimental and is not FDA approved.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • personalized vaccineBiological

    Vaccine will be constructed for each subject that express multiple candidate tumor-derived neoantigens.

  • NivolumabDrug

    Also called Opdivo

    3mg/kg nivolumab will be administered intravenous (IV) infusion every 3 weeks for 4 doses. After 4 doses, 480 mg nivolumab will be administered intravenous (IV) infusion every 4 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing personalized vaccine and Nivolumab in people with Cancer of Gastrointestinal Tract, run by University of California, San Diego 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 4 inclusion and 11 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: withdrawn, as of the sponsor's last update on 10 Jun 2024. 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 combined 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.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Quantitative frequency of TCR (time frame: 1 year). 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?
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 10 Jun 2024.
