Perioperative Durvalumab With Neoadjuvant ddMVAC or Gemcitabine/Cisplatin in Patients With Muscle-invasive Bladder Cancer (NIAGARA-2)
The Phase IIIb NIAGARA-2 study aims to expand on the data from the Phase III NIAGARA study by investigating perioperative durvalumab in combination with investigator-selected cisplatin-based neoadjuvant chemotherapy (either ddMVAC or gemcitabine/cisplatin) in a clinical practice setting.

Study Plan
This section provides details of the study plan, including how the study is designed and what the study is measuring.
How is the study designed?
| Participant Group/Arm | Intervention/Treatment |
|---|---|
EXPERIMENTAL: ddMVAC cohort
| Drug: Durvalumab, Drug: Methotrexate, Drug: Vinblastine, Drug: Doxorubicin, Drug: Cisplatin |
EXPERIMENTAL: gem/cis cohort
| Drug: Durvalumab, Drug: Gemcitabine, Drug: Cisplatin |
What is the study measuring?
Primary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| The safety of neoadjuvant durvalumab combined with ddMVAC or gem/cis prior to radical cystectomy (RC). | Incidence of Grade 3 or 4 \[possibly treatment-related adverse events (PRAEs)\] as observed prior to RC. | Up to 6 months |
Secondary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| The safety and tolerability of perioperative durvalumab combined with ddMVAC or gem/cis. | Incidence, severity, nature, seriousness, intervention/treatment, outcome, and causality of treatment-emergent adverse events, including PRAEs, adverse events of special interest, immune-mediated adverse events, adverse events (AEs), and serious adverse events; AEs resulting in study treatment interruption and discontinuation; laboratory findings. | Up to 2 years |
| The efficacy of perioperative durvalumab combined with ddMVAC or gem/cis in terms of event-free survival (EFS). | EFS is defined as the time from first neoadjuvant durvalumab + chemotherapy treatment until the earliest occurrence of any of the following events: * First recurrence of disease after RC * First documented progression in participants who were medically precluded from RC * Time of expected surgery in participants who refuse to undergo RC or failure to undergo RC in participants with residual disease * Death due to any cause. | Up to 3 years |
| The efficacy of perioperative durvalumab combined with ddMVAC or gem/cis in terms of disease-free survival (DFS). | DFS is defined as the time from the date of RC to the earliest of the first recurrence of disease post RC or death due to any cause. | Up to 3 years |
| The efficacy of perioperative durvalumab combined with ddMVAC or gem/cis in terms of OS. | OS is defined as the time from first neoadjuvant durvalumab + chemotherapy until death due to any cause. | Up to 3 years |
| The efficacy of neoadjuvant durvalumab combined with ddMVAC or gem/cis followed by RC in terms of pathologic complete response (pCR). | pCR rate is defined as the proportion of participants whose pathologic staging is T0N0M0 as assessed per local pathology review using specimens obtained via RC. | Up to 3 years |
| The efficacy of neoadjuvant durvalumab combined with ddMVAC or gem/cis followed by RC in terms of pathologic downstaging (pDS). | pDS rate is defined as the proportion of participants whose pathologic staging is \<P2 per local pathology review using specimens obtained via RC. | Up to 3 years |
