Etude de phase 3, randomisée évaluant l’efficacité l'enfortumab védotine et le pembrolizumab (MK-3475) par rapport à la gemcitabine et au cisplatine en néoadjuvant, chez les patients éligibles au cisplatine ayant un cancer de la vessie invasif musculaire (MK-3475-B15/ KEYNOTE-B15 / EV-304)

Résumé :

The purpose of this study is to assess the antitumor efficacy and safety of perioperative enfortumab vedotin (EV) plus pembrolizumab and radical cystectomy (RC) + pelvic lymph node dissection (PLND) compared with the current standard of care (neoadjuvant chemotherapy [gemcitabine plus cisplatin] and RC + PLND) for participants with MIBC who are cisplatin-eligible. The dual primary hypotheses are preoperative EV + pembrolizumab and RC + PLND (Arm A) will achieve superior pathologic complete response (pCR) rate and perioperative EV and pembrolizumab and RC + PLND (Arm A) will achieve superior event free survival (EFS) compared with neoadjuvant gemcitabine + cisplatin and RC + PLND (Arm B).
