  Purpose
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.

Primary Outcome Measures:
  • Efficacy of MPDL3280A pre-cystectomy with respect to pathological complete response rate (pCRR) [ Time Frame: 2-3 months (timeframe dependent on delay to surgery) ] [ Designated as safety issue: No ]
    Assessment based on pre-treatment tumour sample collected at screening (archival) and post-treatment tumour sample taken at cystectomy. Pathological complete response rate (pCRR) defined as ≥20% reduction in residual disease of the bladder based on histological evaluation of the resected bladder specimen collected during cystectomy (post-treatment).

  • Efficacy of MPDL3280A pre-cystectomy on immune parameters [ Time Frame: 2-3 months (timeframe dependent on delay to surgery) ] [ Designated as safety issue: No ]
    Dynamic changes in T cell subpopulations (CD8 and/or CD3) measured in tumour samples collected pre- and post-treatment.


Secondary Outcome Measures:
  • Safety and tolerability of MPDL3280A when given to this patient population pre-cystectomy [ Time Frame: Approx 34 weeks (from screening registration, throughout treatment and up to 24 weeks post-cystectomy - timeframe dependent on delay to surgery) ] [ Designated as safety issue: Yes ]
    Incidence, nature and severity of adverse events (AEs) and surgical complications will be reviewed.

  • Efficacy of MPDL3280A pre-cystectomy with respect to anti-tumour effects as measured by radiological response (RR) [ Time Frame: Approx 34 weeks (timeframe dependent on delay to pre-cystectomy visit) ] [ Designated as safety issue: No ]
    CT or MRI scan taken at screening and pre-cystectomy visits. RR is defined as a >30% decrease in tumour diameter from the baseline scan.

  • Efficacy of MPDL3280A pre-cystectomy with respect to anti-tumour effects based on disease free survival (DFS) [ Time Frame: Up to 2 years post-cystectomy ] [ Designated as safety issue: No ]
    Disease and survival data is reviewed at post-surgery visits and at 1 and 2 years post-cystectomy.

  • Efficacy of MPDL3280A pre-cystectomy with respect to anti-tumour effects based on overall survival (OS) [ Time Frame: Up to 2 years post-cystectomy ] [ Designated as safety issue: No ]
    Disease and survival data is reviewed at post-surgery visits and at 1 and 2 years post-cystectomy.


Estimated Enrollment: 85
Study Start Date: February 2016
Estimated Study Completion Date: March 2019
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MPDL3280A
Patients receive 2x 3-weekly cycles of MPDL3280A (one infusion on the first day of each cycle) prior to cystectomy surgery.
Drug: MPDL3280A
Intravenous infusion
Other Name: Atezolizumab

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.
