About this study

Official title: A Clinical Study of Engineered Tumor Infiltrating Lymphocytes Injection (GC203 TIL) in Patients With Advanced Gynecologic Tumors

This study is to investigate the safety and efficacy on TIL engineered with membrane-binding cytokine (GC203 TIL) for the treatment of patients with advanced gynecologic tumors. Autologous TILs from tumor resections or biopsies are first gene modified (engineered with membrane-binding cytokine) and than expanded before i.v. infusion into the patient after NMA lymphodepletion treatment with cyclophosphamide.

Being tested
Membrane Bound Cytokine Modified TIL

What participants receive

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

  • Membrane Bound Cytokine Modified TILBiological

    Adoptive transfer of 2x10^8-1x10^10 autologous TIL engineered with membrane-binding cytokine to patients i.v. in 30-120 minutes.

Receives: Biological: Membrane Bound Cytokine Modified TIL

What is being measured

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

  1. Adverse Events (AE)

    To characterize the safety profile of TIL engineered with membrane-binding cytokine (GC203 TIL) in patients with advanced gynecologic tumors as assessed by incidence of adverse events related to GC203 TIL infusion.

    Measured: Up to 6 months

  2. Objective Response Rate (ORR)

    Proportion of patients with response per Response Evaluation Criteria in Solid Tumors (RECIST v1.1):

    ORR (proportion of patients) = # with CR + # with PR / # with CR + # with PR + # with SD + # with PD.

    ( Except baseline evaluation within 28 days before GC203 TIL infusion，PET/CT scan will be performed at 6 weeks after GC203 TIL infusion, and than every 6 weeks for 6 months, and then every 6 months after that for up to 3 years)

    Measured: Up to 36 months

  3. Disease Control Rate (DCR）

    Percentage of patients that meet CR, PR and SD criteria set in this study according to RECIST v1.1： DCR (proportion of patients) = # with CR + # with PR + # with SD / # with CR + # with PR + # with SD + # with PD.

    Measured: Up to 36 months

  4. Duration of Response (DOR)

    The time length between the first confirmed objective response per RECIST 1.1 to the treatment and the subsequent disease progression per RECIST 1.1

    Measured: Up to 36 months

  5. Progression-Free Survival (PFS)

    The time length between GC203 TIL infusion and confirmed subsequent disease progression according to RECIST 1.1

    Measured: Up to 36 months

  6. Overall Survival (OS)

    The length of time from the date of the start of GC203 TIL treatment that the patients are still alive

    Measured: Up to 36 months

Secondary outcomes (1)

  1. Change in Quality of Life

    Comparison of patients' quality of life before and after GC203 TIL treatment as assessed by the EORTC(The European Organization for Reasearch and Treatment of Cancer) QLQ-30(Quality of Life Questionnare-Core30 ) (V3.0). The outcome will be calculated by software from different dimensions.

    Measured: Up to 36 months

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Membrane Bound Cytokine Modified TIL in people with Advanced Gynecologic Tumors and TIL Engineered With Membrane-Binding Cytokine, run by Shanghai Juncell Therapeutics 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 13 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 11 Dec 2025. 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 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?

Adverse Events (AE) (time frame: Up to 6 months). The study lists 6 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 NCT05468307.

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 11 Dec 2025.
