Is this trial a fit for you?
✓Likely a good fit
Adults 18-75 with histologically confirmed solid tumors, at least one measurable lesion, ECOG 0-1, and progression after standard therapy; must have produced GC203 TILs from tumor tissue.
✕Probably not a fit
Patients whose tumors do not respond to GC203 TILs or who experience intolerable side effects may not benefit.

What this trial studies
This is a phase 1, open-label, single-arm study evaluating the safety and potential effectiveness of GC203 TIL therapy in adults with malignant solid tumors. Participants must have had tumor tissue used to produce GC203 TILs and meet specific health criteria, including good performance status and at least one measurable tumor lesion. The study focuses on patients whose disease progressed after standard therapies and are willing to receive the engineered TIL treatment. Outcomes will include safety data and preliminary signals of anti-tumor activity. The trial is conducted at Shenzhen Hospital of Southern Medical University in Shenzhen, China, with Shanghai Juncell Therapeutics as lead sponsor.
Why it matters
Potential benefit: If successful, patients may experience disease control or tumor shrinkage and improved symptoms while awaiting further treatment options.
How similar studies have gone: Other TIL-based therapies have shown safety and some efficacy signals in solid tumors, supporting further exploration of GC203 TIL.
