Acerca de la investigación

This substudy is part of an umbrella platform study which is designed to evaluate investigational agents with or without pembrolizumab in participants with urothelial carcinoma who are in need of new treatment options. Substudy 04A will enroll participants with locally advanced or mUC whose disease is resistant to treatment with programmed cell death-1/ligand 1 (PD-1/L1) inhibitors. The protocol infrastructure will enable the rolling assignment of investigational treatments.

Inclusion Criteria:

The main inclusion and exclusion criteria include but are not limited to the following:

Histologically or cytologically confirmed diagnosis of locally advanced/unresectable or mUC of the renal pelvis, ureter (upper urinary tract), bladder, or urethra.
Arm A: PD-1/L1 refractory locally advanced or mUC as evidenced by: 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.
Arm A: Participants must provide an archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion demonstrating UC, not previously irradiated, and adequate for biomarker evaluation.
Arm B: PD-1/L1 refractory locally advanced or mUC as evidenced by: EITHER disease progression after treatment with an anti-PD-1/L1 mAb for locally advanced/unresectable or mUC administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies; OR disease recurrence after treatment with an anti-PD-1/L1 mAb for MIUC administered as monotherapy or in combination with other checkpoint therapies \>12 months after last dose of treatment with an anti-PD-1/L1 mAb.
Arm B: Participants must provide an archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion from a metastatic site or from a primary tumor that has become locally advanced and not previously irradiated.

Exclusion Criteria:

Known additional nonurothelial malignancy that is progressing or has required active treatment within 3 years prior to study randomization/allocation.
Received prior systemic anticancer therapy including investigational agents within 4 weeks before randomization/allocation.
Active infection requiring systemic therapy.
Received a live or live-attenuated vaccine within 30 days before the first dose of study intervention. Administration of killed vaccines are allowed.
Known history of human immunodeficiency virus (HIV).
Known history of hepatitis B or known hepatitis C virus infection.

Estas medidas indican qué se estudia. No prueban que un tratamiento funcione.

Medidas principales

Percentage of Participants Who Experienced At Least One Adverse Event (AE)

Plazo: Up to approximately 5 years

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.

Percentage of Participants Who Discontinued Study Treatment Due to an AE

Plazo: Up to approximately 5 years

Arm A: Objective Response Rate (ORR) as Assessed by Blinded Independent Central Review (BICR)

Plazo: Up to approximately 2 years

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.

Arm B: ORR as Assessed by Investigator

Plazo: Up to approximately 2 years

ORR is defined as the percentage of participants who achieve a 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. The percentage of participants who experience CR or PR as assessed by the investigator will be presented.

Medidas secundarias

Arm A: Duration of Response (DOR) as Assessed by BICR

Plazo: Up to approximately 2 years

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.

Arm B: DOR as Assessed by Investigator

Plazo: Up to approximately 2 years

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 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 the investigator will be presented.
