Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| PSA | 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. |
| 68Ga-NYM032 PET/CT | **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.\*\* |
