2359O - Phase III THOR study: Results of erdafitinib (erda) vs pembrolizumab (pembro) in pretreated patients (pts) with advanced or metastatic urothelial cancer (muc) with select fibroblast growth factor receptor alterations (FGFRalt)
- Arlene O. Siefker-Radtke (Houston, United States of America)
Abstract
Background
Erda is an oral pan-FGFR tyrosine kinase inhibitor approved to treat locally advanced or mUC in pts with susceptible
Methods
Pts ≥18 y with unresectable advanced/mUC with select
Results
At 15 Jan 2023 data cutoff, intent-to-treat set (median follow-up 33.2 mo) comprised 175 pts in erda and 176 in pembro arm. The primary end point was not met, with no statistically significant difference in OS between tx arms (Table). Erda had numerically longer PFS and numerically higher ORR but shorter duration of response. Most common tx-related adverse events (TRAEs) of any grade: hyperphosphatemia (73%), stomatitis (45%), diarrhea (45%), and dry mouth (35%) with erda; pruritus (12%), asthenia (10%), hypothyroidism (10%), and fatigue (10%) with pembro. Gr 3-4 TRAEs and serious TRAEs occurred in 43% and 13% in erda and 12% and 10% in pembro arm, respectively. TRAEs leading to death occurred in 0 pts in erda and 3 (2%) in pembro arm. 15% of pts discontinued erda and 5% discontinued pembro due to TRAEs. All data are value (95% CI). aNominal p estimate, due to primary end point not being met.
Erda (n=175) Pembro (n=176) 10.9 (9.2-12.6) 11.1 (9.7-13.6) 1.18 (0.92-1.51) p=0.18 4.4 (4.1-5.5) 2.7 (1.6-3.0) 0.88 (0.70-1.10) p=0.26a 40.0 (32.7-47.7) 21.6 (15.8-28.4) 1.85 (1.32-2.59) p<0.001a 4.3 (3.7-6.9) 14.4 (7.4-27.8)
Conclusions
Erda and pembro had similar OS in this anti–PD-(L)1 naive,
