TROPHY-U-01

After platinum chemotherapy and checkpoint inhibition, what activity did sacituzumab govitecan show in advanced urothelial carcinoma?

Population
113 patients with locally advanced unresectable or metastatic urothelial carcinoma progressing after platinum chemotherapy and a checkpoint inhibitor (cohort 1).
Experimental treatment
Sacituzumab govitecan 10 mg/kg IV on days 1 and 8 of each 21-day cycle.
Comparator
Single-arm phase II cohort; no randomized comparator.
Study design
Single-arm phase II study

10.9 months

At median follow-up of 9.1 months, ORR was 27%; median PFS was 5.4 months and median OS 10.9 months. Grade ≥3 treatment-related neutropenia occurred in 35%, leukopenia 18%, anaemia 14% and diarrhoea 10%.

Critical appraisal

Single-arm evidence and historical comparisons are vulnerable to selection bias. The subsequent confirmatory TROPiCS-04 study did not establish the required benefit, and the US accelerated approval for urothelial carcinoma was withdrawn in November 2024.

Absolute-effect discipline: NNT/NNH is not calculated unless a defensible absolute difference and a common time horizon are available. Median survival differences and hazard ratios alone are not converted into NNT.

Current-practice context

Reviewed 2026-10-14; this is a dated evidence-context note, not a substitute for local guidelines or individual clinical judgement.

Historical evidence only for the withdrawn US urothelial indication; do not present sacituzumab govitecan as a currently FDA-approved standard for urothelial carcinoma. Regulatory status differs by jurisdiction and should be checked locally.

Freshness status: this page has a dated context and source links, but is not a claim that every relevant guideline or subsequent publication has been exhaustively reviewed.
