Avelumab approved in Canada for frontline maintenance in bladder cancer


The approval was based on findings from the phase 3 JAVELIN Bladder 100 study.

Health Canada has approved the PD-L1 inhibitor avelumab (Bavencio) for the maintenance treatment of patients with unresectable locally advanced or metastatic urothelial carcinoma whose disease has not progressed following first-line platinum-based chemotherapy.1

The approval was based on data from the phase 3 JAVELIN Bladder 100 study, in which the median overall survival (OS) was 21.4 months with avelumab plus best supportive care (BSC) compared with 14.3 months with BSC alone.2 This 7.1-month benefit translated to a 31% reduction in the risk of death (HR, 0.69; 95% CI, 0.56-0.86; P <.001).

The open-label, international JAVELIN Bladder 100 trial included 700 patients with locally advanced or metastatic urothelial cancer who achieved a complete response (CR), partial response (PR), or stable disease (SD) after receiving 4 to 6 cycles of standard gemcitabine combined with either cisplatin or carboplatin.

Patients were randomized in a 1:1 ratio to intravenous avelumab (10 mg/kg every 2 weeks in 4-week cycles) plus BSC or BSC alone. Specific components of BSC could be correction of metabolic disorders, antibiotics, pain management, nutritional support, and symptom control.

The primary end point was OS, with key secondary end points including progression-free survival and safety.

The investigators reported that the avelumab OS benefit was observed across patient subgroups, including those defined by best response to treatment (CR, PR, or SD), and choice of frontline platinum chemotherapy (carboplatin or cisplatin).

Biomarker testing showed that 51% (n = 358) of patients were PD-L1 positive across the overall study population. In this subgroup, avelumab plus BSC induced a 44% reduction in the risk of death compared with BSC alone (HR, 0.56; 95% CI, 0.40-0.79; P <.001). An exploratory analysis was also conducted among PD-L1–negative patients (n = 271), showing a hazard ratio for OS of 0.85 (95% CI, 0.62-1.18).

Adverse events (AEs) across all grades occurred in 98% versus 77.7% of the avelumab and control groups, respectively. Grade 3 AEs occurred in 47.4% versus 25.2% of the 2 arms, respectively.

In the United States, the FDA approved avelumab in July 2020 for use in this setting. The PD-L1 inhibitor is also nearing approval in the European Union for this indication.
