Primary Outcome Measures
NameTimeMethod
Dose Limiting Toxicity (DLT) (Phase 1)Up to 2 years follow up

Incidence of adverse events, serious adverse events, and clinical laboratory abnormalities defined as dose-limiting toxicities (DLTs).

Maximum Tolerated Dose (MTD) (Phase 1)Up to 2 years follow up

The maximum tolerated dose is among the explored dose levels.

Recommended Phase 2 Dose (RP2D) (Phase 1)Up to 2 years follow up

To identify the expansion phase dose of Lutetium Lu 177 JH020002 Injection.

PSA response rateUp to 3 years follow up

PSA response rate is the proportion of PSA responders, defined as a participant who has achieved PSA decrease of \>= 50% from baseline that is confirmed by a second consecutive PSA measurement \>= 4 weeks later. Determination of response status will be based on PCWG3 recommendations.

Secondary Outcome Measures
NameTimeMethod
Maximum plasma concentration (Cmax)Up to 2 years follow up

Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.

Radiation DosimetryUp to 2 years follow up

Absorbed dose estimated in organs and tumor lesions.

Area under the plasma concentration-time curve from time zero to the last measurable concentration (AUC0-t)Up to 2 years follow up

Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.

Area under the plasma concentration-time curve from time zero extrapolated to infinite time (AUC0-inf)Up to 2 years follow up

Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.

Volume of distribution (Vz) during the terminal phase following intravenous eliminationUp to 2 years follow up

Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.

Radiographic Progression-free Survival (rPFS)Up to 3 years follow up

Radiographic progression free survival (rPFS) is defined as the time of radiographic progression by Prostate Cancer Working Group 3 (PCWG3)-modified RECIST V1.1.

Disease control Rate (DCR)Up to 3 years follow up

Disease control rate (DCR) is defined as the proportion of participants with best overall response of complete response or partial response or Stable disease in soft tissue according to PCWG3 modified RECIST 1.1.

Duration of Response (DoR)Up to 3 years follow up

Duration of response (DOR) is defined as the duration of time between the date of first documented response (CR or PR) in soft tissue as per BIRC and according to PCWG3 modified RECIST 1.1, and the date of first documented progression or death due to any cause.

Time to First Subsequent Therapy (TFST)Up to 3 years follow up

Time to First Subsequent Therapy (TFST) is defined as the time from the date of first administration of investigational drug to the date of the first subsequent therapy of the prostate cancer.

Overall Survival (OS)Up to 3 years follow up

Overall survival (OS) is defined as the time from the date of first administration of investigational drug to the date of death due to any cause.

Time to Symptomatic Skeletal Event (TTSSE)Up to 3 years follow up

Time to a first symptomatic skeletal event (TTSSE) is defined as date of first administration of investigational drug to the date of first new symptomatic pathological bone fracture, spinal cord compression, tumor-related orthopedic surgical intervention, requirement for radiation therapy to relieve bone pain or death from any cause, whichever occurs first.

Incidence and severity of Adverse Events (AEs) and Serious Adverse Event (SAEs)Up to 3 years follow up

Analysis of frequencies and severity for Adverse Events (AEs) and Serious Adverse Event (SAEs), through the monitoring of relevant clinical and laboratory safety parameters.

Objective Response Rate (ORR) (Phase 2)Up to 2 years follow up
