23/🔑SUMMARY🔑

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)

19/TROPiCS-04
Ph3 RCT SG vs chemo in pretx mUC
🚫sig. improvmt in OS w/ SG compared to taxane or VIN

mOS: SG 10.3 vs chemo 9.0mo
(HR:0.86; 95% CI:0.73–1.02; p=0.087)
Grade ≥3️ TRAEs (SG): Neutropenia(35%; FN 12%), diarrhea (15%)
G5 AEs: SG 7% (16 inf w neutropenia), chemo 2%

18/🔬TROPHY-U-01 Cohort 3 trial safety of sacituzumab govitecan👇

TRAEs led to➡️
✋SG interruptions in 46%
⬇️SG dose reduction in 39%
🛑SG d/c in 15%

17/#TROPHYU01 Cohorts 1,2,3👇
1️⃣=113 pts who progrs'd after plat chemo+ICI
✅Notable efficacy compared to hist cntls
Led to accel approval 2021

2️⃣=38 cisplatin-inelig pts s/p ICI tx
✅ORR=32%

3️⃣= 41 pts who progrs'd after plat chemo w 2L SG+pembro
✅ORR=41%
mPFS=5.3m

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

15/🏁What about T-DXd in mUC?
1st tumor agnostic ADC w FDA approval for Tx-refractory HER2+ IHC3+ Cas

From DESTINY-PanTumor02
16 pts w/ HER2 IHC3+ mUC
56.3% ORR, mPFS 7.4mo, mOS 13.4mo
No significant neuropathy
🔑AEs: pneumonitis, neutropenia, N/V, left ventricular dysfunction
pgrivasmdphd.bsky.social
14/💡For phosphate of 8.0 mg/dL, withhold erdafitinib & restart once phosphate <5.5 mg/dL

🙌Erdafitinib=good option for pts w susceptible FGFR3 alt

⚖️What about pts who progress after 1L tx & no FGFR3 alt?
⚖️How does the changing 1L tx landscape w EV+P affect choice of 2L tx?
pgrivasmdphd.bsky.social
11/Erda. Safety
Grade ≥3 TRAEs occurred in 45.9% w erdafitinib & 46.4% w chemo

⚖️Most AEs w erdafitinib manageable w dose modification & best supportive care
🛑Tx d/c rates 8.1% w erdafitinib & 13.4% w chemo

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)

7/ IMvigor130 safety results 👇

🎯 Fewer AEs ➡️ withdrawal of any agent in atezo only group
🎯 Most common TRAEs mainly related to chemo
✓ Anemia
✓ Neutropenia
✓ Thrombocytopenia

6/Atezolizumab EMA approved as monotx
✓1L in cisplatin-ineligible + PD-L1 +ve
Based on IMvigor 210 & 130 trials

🔬IMvigor 130:
✅mPFS significantly longer in atezo+plat/Gem vs plat/Gem alone
🚫mOS not sign. longer in atezo grps vs plat/Gem alone

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)

4/Preferred 2L tx for cisplatin-ineligible pts after 1L ICI monoTx
✅EV or ➡️gem + carbo or ➡️erdafitinib (if FGFR alt+)

👉Pembro alone is one of2L tx options for pts who progress after 1L platinum-based chemo and have not received ICI
#OncSky

3/Chemo-naive cisplatin eligible pts
👇Post-1L IO monotx👇
💡2L gem+cisplatin (or ddMVAC) pref'd
💡Erda for FGFR3 mut/fusion (THOR level 1 evidence for erda post-IO)

👉Cisplatin ineligible pts can get gem+carbo or EV (or erda if FGFR3+ alt)
