Brief Title: Preoperative MPDL3280A in Transitional Cell Carcinoma of the Bladder
Official Title: A Phase II Study Investigating Preoperative MPDL3280A in Operable Transitional Cell Carcinoma of the Bladder (ABACUS)
Study ID: NCT02662309
Brief Summary: ABACUS is an open-label, international, multi-centre, window of opportunity phase II trial for patients with histologically confirmed (T2-T4a) transitional cell carcinoma of the bladder. The trial aims to test the efficacy of preoperative MPDL3280A and will include extensive biomarker work on samples from these patients. Eligible patients will receive two 3-weekly cycles of MPDL3280A pre-cystectomy. Following cystectomy, patients will be followed up for safety, survival, and disease data.
Detailed Description: MPDL3280A (also called atezolizumab) is an immune check point inhibitor which targets programmed death-ligand 1 (PD-L1). Overexpression of PD-L1 prevents the immune system from eradicating cancerous cells as it blocks antigen recognition. MPDL3280A inhibits this interaction, allowing immune-mediated tumour cell killing.
