Galectin-3 levels and outcomes with PD-1/PD-L1 therapy in kidney, bladder, lung, and liver cancer
Official title: Association Between Galectin-3 Levels and Outcomes in Patients With Renal Cell Carcinoma, Transitional Cell Carcinoma , Non Small Cell Lung Cancer, and Hepatocellular Carcinoma, Treated With PD-1/PDL-1 Inhibitors
Run by Tel-Aviv Sourasky Medical Center · NCT07485114 · Data updated 2026-11-12
This study tests whether blood galectin‑3 levels before treatment predict outcomes for people with kidney, bladder, lung, or liver cancer who are starting PD‑1/PD‑L1 immunotherapy.

Is this trial a fit for you?
✓Likely a good fit
Adults (aged 18 or older) with renal cell carcinoma, transitional cell carcinoma, non‑small cell lung cancer, or hepatocellular carcinoma who are scheduled to start PD‑1/PD‑L1 therapy and can give informed consent are eligible.
✕Probably not a fit
People not receiving PD‑1/PD‑L1 therapy, those already past their first treatment cycle, or pregnant/lactating individuals are unlikely to benefit from participating in this observational biomarker study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study will measure baseline serum galectin‑3, routine blood counts, and chemistry including liver function in patients with renal cell, transitional cell, non‑small cell lung, or hepatocellular carcinoma who are about to begin PD‑1/PD‑L1 inhibitors. Patients will be followed while receiving standard-of-care immunotherapy to record clinical outcomes and immune‑related side effects. The goal is to correlate pre-treatment galectin‑3 levels with treatment response, progression, and toxicity. No investigational drugs are given; all treatments follow normal clinical practice and the study only collects blood and safety data.
Why it matters
Potential benefit: If successful, a simple blood test for galectin‑3 could help identify who is more likely to benefit from PD‑1/PD‑L1 drugs and who may be at higher risk for side effects.
How similar studies have gone: Preclinical work and small clinical reports link galectin‑3 to PD‑L1 expression and immune resistance, but using baseline serum galectin‑3 as a predictive biomarker for immunotherapy response remains relatively novel and not yet widely validated.
