Purpose: to assess efficacy and safety of Dato-DXd + rilvegostomig as adjuvant therapy versus SoC in MIUC participants with high-risk residual disease after radical resection.
Study details:
Duration: ~78 months (6.5 years) from FSI to last subject visit Treatment length: up to ~12 months, depending on randomized arm Visit frequency: every 3 weeks in Arms 1 and 2; every 2-4 weeks per SoC in Arm 3
Inclusion criteria:
Participant must be > 18 years of age at the time of signing the ICF.
Histologically confirmed MIUC of the bladder or upper tract.
Completed R0 radical resection 28 to 120 days before randomisation, with negative margins and no residual or metastatic disease.
Pathologic evidence of urothelial carcinoma at high-risk of recurrence and
No evidence of disease at screening,
ECOG performance status of 0 or 1 with no deterioration over the previous 2 weeks prior to randomisation.
Minimum life expectancy of > 12 weeks at time of screening.
An archival surgical tumour sample must be available pre-randomisation for central testing.
Adequate organ and bone marrow function within 28 days before randomisation.
