Abstract

Background

Nivolumab has shown promising efficacy and acceptable safety in an open-label, multicenter phase I/II study in patients (pts) with mUC after ≥1 prior platinum-based therapy (NCT01928394). Here we report updated efficacy and safety results for the overall population based on additional follow-up and outcomes by differing levels of PD-L1 expression.

Methods

Pts with mUC, unselected by PD-L1 expression status, received nivolumab 3 mg/kg IV every 2 wk until progression or discontinuation. Pts who met protocol criteria could continue treatment beyond progression and cross over to nivolumab + ipilimumab. Tumor PD-L1 membrane expression was assessed with Dako PD-L1 immunohistochemical staining. Primary endpoint: objective response rate (ORR; RECIST 1.1); other endpoints: safety, progression-free survival (PFS), overall survival (OS), and duration of response.

Results

Of 78 treated pts (median age 65.5 years; range, 31–85), 52 received ≥2 prior therapies. At a minimum follow-up of 9 months, 23.1% of pts are on monotherapy and 23.1% switched to combination. Treatment discontinuation was mainly due to disease progression. PD-L1 was evaluable in 67 pts (86%). Table shows overall efficacy. In pts with PD-L1 expression ≥1% (n = 25) vs

Conclusions

Nivolumab showed encouraging efficacy and acceptable safety regardless of PD-L1 expression in previously treated, unselected pts with mUC.
