- Primary Outcome Measures
Name Time Method 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 rate Up 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
Name Time Method Maximum plasma concentration (Cmax) Up to 2 years follow up Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.
Radiation Dosimetry Up 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 elimination Up 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 Proportion of participants with Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR). ORR was based on the Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria response for patients with measurable disease at baseline.
Time to maximum plasma concentration (Tmax) Up to 2 years follow up Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.
Terminal elimination half-life (t1/2) Up to 2 years follow up Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.
Total systemic clearance (CL) Up to 2 years follow up Pharmacokinetics (PK) characterization of Lutetium Lu 177 JH020002.
