Testing a new method to predict response to immunotherapy in bladder cancer patients

Evaluation de l'Association Entre Les résultats d'un Test in Vitro en Cours de développement (SPHERTEST) et la réponse Aux Traitements Par Inhibiteur du Point de contrôle Chez Des Patients Atteints de Carcinome urothélial de Stade avancé ou métastatique.

Centre Hospitalier Universitaire de Nīmes · NCT06738797

This study is testing a new test called SPHERTEST to see if it can help doctors figure out which bladder cancer patients are likely to respond well to immunotherapy after chemotherapy.

What this trial studies

This observational study investigates the association between the SPHERTEST in vitro test and the response to checkpoint inhibitor treatments in patients with advanced or metastatic urothelial carcinoma. It aims to identify biomarkers that can predict which patients are likely to benefit from immunotherapy following platinum-based chemotherapy. The study will include patients who have consented and meet specific eligibility criteria, focusing on those with histologically confirmed urothelial carcinoma. The SPHERTEST will be utilized to assess the potential effectiveness of immunotherapy in these patients.

Who should consider this trial

Good fit: Ideal candidates include patients with histologically proven advanced or metastatic urothelial carcinoma who are eligible for immunotherapy.

Not a fit: Patients who have received anti-PD1, anti-PDL1, or anti-CTLA4 treatments within the past year may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help tailor immunotherapy treatments to individual patients, improving outcomes for those with advanced bladder cancer.

How similar studies have performed: Other studies have shown promise in using biomarkers to predict responses to immunotherapy, but this specific approach with SPHERTEST is novel.
