2L & later line tx in mUC 👉Erdafitinib FDA-approved w/ FGFR3 alt after prior tx 🎉NCCN guidelines updated Jan 2025 🔬Ongoing trials for SG in diff clin scenarios ✔️T-DXd for HER2 IHC3+ (based on gastric cancer scoring algorithm)
21/Why TROPiCS4 neg for OS? Hard to est, consider: 🔸Late-line,hvly pretx pop 🔸Ltd primary G-CSF prophy in SG arm(~20%) 🔸~5% pts randomized to control never rec’d tx(~2% in SG arm) 🚫biomarker selection(UGT1A1 gene polym→⬆️tox?) 🔸~20% in each arm rec'd salvage EV(confounding)
16/Sacituzumab govitecan(SG) an ADC 🎯Trop-2 An active agent in mUC but failed to show stat. significant longer OS over taxane or vinflunine (VIN) in TROPiCS-04
✅FDA approval w/drawn~Oct 2024 👉Let’s look @ original approval & possible reasons for a negative P3 trial
8/Even w pembro➡️24 mo PFS rate in KEYNOTE-045 was 12.4%👉Pts likely to need subsequent line tx
🧐NCCN guidelines RE: next tx? Options (if not given prior): 🔶EV 🔶Erda for FGFR3 alt 🔶T-DXd for HER2 IHC 3+ (gastric Ca scoring) 🔶Saci(indication withdrawn, still in NCCN gdlns)
🎯 Fewer AEs ➡️ withdrawal of any agent in atezo only group 🎯 Most common TRAEs mainly related to chemo ✓ Anemia ✓ Neutropenia ✓ Thrombocytopenia #OncSky
5/Other 2L options(depending on prior tx): ✔️Erda for FGFR3 alterations ✔️EV monotx Taxane if no access to☝️
✔️Nivo or avelumab if no access to pembro + ICI naïve ✔️T-DXd for HER2 3+ IHC (gastric Ca scoring) ✔️Sacituzumab govitecan (FDA indication withdrawn) @pcvblack.bsky.social#OncSky
