EXPERIMENTAL: Zilovertamab vedotin
Participants will receive zilovertamab vedotin 2mg/kg administered on Day 1 and Day 8 of each 3 week cycle (Q3W) until documented disease progression or any other discontinuation criterion is met.
BIOLOGICAL: Zilovertamab vedotin
Administered via intravenous (IV) infusion on day 1 and day 8 of Q3W cycles
The main inclusion and exclusion criteria include but are not limited to the following:
EITHER disease progression while on treatment or after treatment with an anti-PD-1/L1 monoclonal antibody (mAb) for locally advanced/unresectable or mUC administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies OR disease recurrence while on treatment or after treatment with an anti-PD-1/L1 mAb for muscle-invasive urothelial carcinoma (MIUC) administered as monotherapy.
Percentage of Participants Who Experienced At Least One Adverse Event (AE)
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.
Up to approximately 5 years
Percentage of Participants Who Discontinued Study Treatment Due to an AE
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment
Up to approximately 5 years
Objective Response Rate (ORR)
ORR is defined as the percentage of participants who achieve a Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented.
Up to approximately 2 years
Duration of Response (DOR)
For participants who demonstrate confirmed CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by Blinded Independent Central Review (BICR) will be presented.
Up to approximately 2 years
