Official title: Efficacy and Safety of Autologous Tumor-Infiltrating Lymphocytes (TIL) Therapy Combined With Pembrolizumab (Keytruda) Immunotherapy in Patients With Advanced or Metastatic Refractory Stomach and Esophageal Cancer

This Phase I/II study evaluates the safety and efficacy of autologous tumor-infiltrating lymphocytes (TIL) therapy combined with Pembrolizumab (Keytruda) immunotherapy in patients with advanced or metastatic refractory stomach and esophageal cancer. Lifileucel (Amtagvi), the first FDA-approved TIL therapy, has shown significant promise in treating unresectable or metastatic melanoma by leveraging the patient's own immune cells to target and destroy cancer cells. This study aims to apply a similar approach to stomach and esophageal cancers. TILs will be harvested from patients' tumors, expanded in vitro, and infused back into the patients following a non-myeloablative lymphodepletion regimen. Pembrolizumab, a monoclonal antibody that targets the PD-1 receptor on T cells, will be administered to enhance the immune response. The primary endpoint is to determine the objective response rate (ORR) of this combined therapy. Secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), duration of response (DOR), and quality of life (QoL). This trial aims to provide a novel, personalized treatment option for patients with limited therapeutic alternatives.

Read the detailed description

Tumor-infiltrating lymphocytes (TILs) therapy is an advanced form of adoptive cell therapy that harnesses the patient's immune cells to fight cancer. Lifileucel (Amtagvi), the first FDA-approved TIL therapy, has demonstrated substantial efficacy in treating unresectable or metastatic melanoma. By extracting lymphocytes from the patient's tumor, expanding them ex vivo, and reinfusing them, Lifileucel has shown to significantly enhance the immune system's ability to target and destroy cancer cells. This promising approach serves as the foundation for the current study, aiming to apply a similar methodology to advanced or metastatic refractory stomach and esophageal cancers, which typically have poor prognoses and limited treatment options.

This trial involves a multi-step treatment process. First, tumor samples are collected from patients for TIL extraction. Following this, a lymphodepletion regimen using cyclophosphamide and fludarabine is administered to prepare the body for the infusion of expanded autologous TILs. After the TIL infusion, Aldesleukin (IL-2) is given to stimulate the TILs' activity. Pembrolizumab (Keytruda), an immunotherapy that targets the PD-1 receptor on T cells, is also administered to further enhance the immune response against the tumor.

The primary goal of this trial is to determine the objective response rate (ORR) of this combined therapy. Secondary endpoints include the disease control rate (DCR), progression-free survival (PFS), overall survival (OS), duration of response (DOR), and changes in the quality of life (QoL) of patients.

Patients will be closely monitored for side effects and reactions during their hospital stay and throughout the follow-up period. Safety will be assessed based on the incidence and severity of adverse events, while efficacy will be evaluated using RECIST v1.1 criteria. By leveraging the patient's own immune cells and combining them with advanced immunotherapies, this trial aims to provide a novel, personalized treatment option for patients with advanced or metastatic refractory stomach and esophageal cancer, building on the success observed with Lifileucel (Amtagvi) in melanoma treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Tumor Infiltrating Lymphocytes (TIL), Cyclophosphamid and Fludarabine in people with Stomach Cancer and Stomach Cancer Recurrent, run by Essen Biotech at 1 site in China.

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 23 inclusion and 14 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: looking for participants now, as of the sponsor's last update on 12 Nov 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 China. 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?

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?

Contact Rhoda M Smith, Phd (+12077706670, clinical-trials@essen-biotech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse Events (time frame: 6 months). 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 12 Nov 2024.
