Prostatic Neoplasm Clinical Trial
— PSMACareOfficial title:
An International Prospective Open-label, Multi-center, Randomized, Non-comparative Phase II Study of Lutetium [177Lu] Vipivotide Tetraxetan (AAA617) Alone and Lutetium [177Lu] Vipivotide Tetraxetan (AAA617) in Combination With Androgen Receptor Pathway Inhibitors in Patients With PSMA PET Scan Positive Castration-Resistant Prostate Cancer
The purpose of this study is to evaluate the efficacy and safety of AAA617 alone (Lutetium [177Lu] vipivotide tetraxetan) and in combination with an Androgen Receptor Pathway Inhibitors (ARPI) in participants with PSMA-positive, castration-resistant prostate cancer and no evidence of metastasis in conventional imaging (CI) (i.e., CT/MRI and bone scans). Approximately 120 participants will be randomized.

The total score range is between 1-108, higher scores indicates better for total score and subscale scores. PCS is a 12-item prostate cancer subscale that asks about symptoms and problems specific to prostate cancer (Range 0-48, higher scores better). The FACT-P total score is the sum of all 5 subscale scores of the FACT-P questionnaire and ranges from 0-156. Higher scores indicate higher degree of functioning and better quality of life. | From date of randomization until end of efficacy follow-up, up to 5 years | |
Secondary | Functional Assessment of Cancer Therapy - Radiotherapies (FACT-RNT) Questionnaire | The FACT-RNT is assessing treatment-related symptoms of special interest/associated with Radionuclides Therapies. The FACT-RNT contains 15 items assessing dry mouth, dry eyes, difficulty urinating, nausea, vomiting, diarrhea, constipation, loss of appetite, fatigue, impact of fatigue, pain, bone pain, pain interference, bothered by of side effects of treatment and isolation due to illness or treatment. | From date of randomization until end of efficacy follow-up, up to 5 years | |
Secondary | Brief Pain Inventory - Short Form (BPI-SF) Questionnaire | The BPI-SF is a publicly available instrument to assess the pain and includes severity and interference scores. BPI-SF is an 11-item selfreport questionnaire that is designed to assess the severity and impact of pain on daily functions of a participant. Pain severity score is a mean value for BPI-SF questions 3, 4, 5 and 6 (questions inquiring about the extent of pain, where the extent is ranked from 0 [no pain] to 10 [pain as bad as you can imagine]). Pain severity progression is defined as an increase in score of 30% or greater from baseline without decrease in analgesic use. | From date of randomization until end of efficacy follow-up, up to 5 years |
