Study of Lutetium (177Lu) Vipivotide Tetraxetan in mCRPC Participants With Moderately and Severely Impaired and With Normal Renal Function

Inclusion Criteria

• An Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
• 68Ga-PSMA-11 Positron emission tomography (PET)/CT scan positive, and eligible as determined by the sponsor's central reader.
• A castrate level of serum/plasma testosterone (< 50 ng/dL or < 1.7 nmol/L).
• Documented progressive mCRPC will be based on at least 1 of the following criteria:
• Serum/plasma Prostate-Specific Antigen (PSA) progression defined as 2 consecutive increases in PSA over a previous reference value measured at least 1 week prior. The minimal start value is 2.0 ng/mL
• Soft-tissue progression defined as an increase >= 20% in the sum of the diameter (SOD) (short axis for nodal lesions and long axis for non-nodal lesions) of all target lesions based on the smallest SOD since treatment started or the appearance of one or more new lesions.
• Progression of bone disease: evaluable disease or new bone lesions(s) by bone scan (2+2 PCWG3 criteria)
• Documented stable chronic renal disease without evidence of further deterioration in renal function (stable chronic renal disease is defined as no significant change in renal function within 4 weeks prior to study entry.
• Kidney function based on eGFR by Modification of Diet in Renal Disease (MDRD) equation:
• Normal renal function: participants with eGFR >= 90 mL/min/1.73m2
• Moderate renal impairment: participants with eGFR >= 30 to =< 59 mL/min/1.73m2
• Severe renal impairment: participants with eGFR >= 15 to =< 29 mL/min/1.73m2 Key

Exclusion Criteria

• Previous treatment with PSMA-targeted radioligand therapy.
• Previous treatment with any of the following within 6 months of enrollment confirmation: Strontium-89, Samarium-153, Rhenium-186, Rhenium-188, Radium-223 or hemi-body irradiation.
• Use of agents known to prolong the QT interval from start of screening to end of Cycle 1, unless they can be permanently discontinued for the duration of study.
• Current severe urinary incontinence, hydronephrosis, severe voiding dysfunction, any level of urinary obstruction requiring indwelling/condom catheters. Participants with postrenal impairment, like obstructions, retroperitoneal fibrosis (eg after prostatectomy) must be excluded or first resolved to ≤ Grade 1.
• History or current diagnosis of ECG abnormalities indicating significant risk of safety for participants participating in the study such as:
• Concomitant clinically significant cardiac arrhythmias, e.g. sustained ventricular tachycardia, and clinically significant second- or third-degree AV block without a pacemaker.
• History of familial long QT syndrome or known family history of Torsades de Pointe.
• Resting heart rate (12 lead ECG) <60 bpm Other protocol-defined inclusion/exclusion criteria may apply.
