Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
PSA
Time Frame: 5-6 weeks after each administration.
PSA levels can be used to monitor the treatment efficacy, disease progression, or recurrence of prostate cancer. A decrease in PSA levels after treatment usually indicates effective therapy, while an increase in PSA levels may suggest disease recurrence or progression.
5-6 weeks after each administration.
68Ga-NYM032 PET/CT
Time Frame: **5-6 weeks after the second and fourth administrations in the same dose-escalation cohort.**
**Reflect the PSMA expression level in the patient's lesions.**
**5-6 weeks after the second and fourth administrations in the same dose-escalation cohort.**
