Key Inclusion Criteria: 1. An Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 2. 68Ga-PSMA-11 Positron emission tomography (PET)/CT scan positive, and eligible as determined by the sponsor's central reader. 3. A castrate level of serum/plasma testosterone (\< 50 ng/dL or \< 1.7 nmol/L). 4. 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) 5. 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. 6. 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: 1. Previous treatment with PSMA-targeted radioligand therapy. 2. 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. 3. 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. 4. 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. 5. 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.
