Abstract 3789

Background

In the open-label, phase 3 KEYNOTE-045 study (NCT02256436), overall survival (OS) was significantly longer with pembro vs investigator’s choice of chemo (median, 10.3 vs 7.4 mo; hazard ratio [HR], 0.73; P = 0.002) in recurrent, advanced UC. In a post hoc analysis, pembro was compared with the individual agents in the chemo arm.

Methods

Pts with histologically or cytologically confirmed UC, progression after platinum, ECOG PS 0-2, measurable disease (RECIST v1.1), and ≤2 lines of systemic therapy were randomly assigned 1:1 to pembro 200 mg Q3W or investigator’s choice of paclitaxel 175 mg/m2 Q3W, docetaxel 75 mg/m2 Q3W, or vinflunine 320 mg/m2 Q3W. Primary end points: OS and PFS (RECIST v1.1, blinded central review). ORR (RECIST v1.1, blinded central review) was a secondary end point.

Results

525 pts were included in these analyses (allocation: pembro, 270; paclitaxel, 84; docetaxel, 84; vinflunine, 87). Baseline demographics were generally balanced among the 4 groups. Median follow-up was 14 mo (range, 10-22 mo). Pembro was associated with an OS benefit over the individual chemo agents (HR [95% CI]: paclitaxel, 0.77 [0.57-1.06]; docetaxel, 0.78 [0.56-1.08]; vinflunine, 0.71 [0.52-0.96]). PFS was similar between pembro and each of the chemo agents. ORR (95% CI) was 21% (16%-27%) with pembro vs 12% (6%-21%), 6% (2%-13%), and 18% (11%-28%) with paclitaxel, docetaxel, and vinflunine, respectively. Treatment-related AEs occurred in 61% (pembro), 88% (paclitaxel), 92% (docetaxel), and 91% (vinflunine) of pts. 15% (pembro), 44% (paclitaxel), 54% (docetaxel), and 51% (vinflunine) experienced treatment-related AEs of grade ≥3 severity.

Conclusions

Results from subgroup analyses of KEYNOTE-045 demonstrate that pembro was associated with longer OS, higher antitumor activity, and lower incidence of toxicities than single-agent paclitaxel, docetaxel, or vinflunine in pts with advanced UC that progressed on/after platinum-based therapy. Pembro is the first agent to demonstrate OS improvement vs chemo in this setting and should be considered for use in recurrent, advanced UC.
