Prostate Cancer
Conditions
Brief summary
Single-center, non-commercial phase 2 clinical trial to evaluate 177Lu-PSMA as a systemic adjuvant treatment in patients with high and very high risk prostate cancer after radical treatment using locoregional teleradiotherapy and hormone therapy
Detailed description
The intervention will consist of a single administration of 177Lu-PSMA in the research arm. Both the study and control groups will receive standard hormone therapy. The study population includes 200 adult men with high-risk or very high-risk prostate cancer, with no signs of cancer dissemination in radiological examinations after completion of radiotherapy and continued hormone therapy Participation time in the Study: intervention phase - 1 day; observation phase - 5 years
Interventions
The intervention will consist of a single administration of 7,4 GBq of lutetium (177Lu) vipivotide tetraxetan

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment effectiveness | 2 and 5 years after end of treatment | Assessment of treatment failure - the assesment of biochemical progression ratio, defined as a rise of PSA by 2 ng/mL or more above the nadir, proven by a consecutive examination performed at least 4 weeks later |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Biochemical progression-free survival | During the intervention and follow up period (assessed up to 5 years) | Comparative assessment of biochemical progression-free survival time defined as an increase in tPSA (prostate specific antigen) in the blood above the nadir (the lowest PSA value after completion of treatment) by 2 ng/mL or more, confirmed in the next test performed no earlier than after 4 weeks |
| Radiological progression-free survival | During the intervention and follow up period (assessed up to 5 years) | Comparative assessment of radiological progression-free survival defined according to PCWG3 criteria |
| Time until the next therapeutic intervention | During the intervention and follow up period (assessed up to 5 years) | Comparative assessment of the time until the next therapeutic intervention |
| Incidence of Treatment-Emergent Adverse Events according to CTCAE v 5.0 | During the intervention and follow up period (assessed up to 5 years) | Comparative assessment of safety and tolerability of treatment according to CTCAE v 5.0 |
| Quliaty of life | During the intervention and follow up period (assessed up to 5 years) | Comparison of EORTC QLQ-PR25 quality of life indicators between study groups |
