Study Description
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.
Interventions
AAA517
AAA617
ADT
ARPI
Best supportive care
Piflufolastat F 18
Eligibility Criteria
Key Inclusion criteria
Participants must be adults ≥ 18 years of age with signed informed consent prior to participation to study
Histologically or cytologically confirmed prostate cancer
Participants must have ongoing androgen deprivation therapy with a GnRH agonist/antagonist or prior bilateral orchiectomy
Castrate level of serum testosterone (< 1.7 nmol/l [50 ng/dl]) on GnRH agonist or antagonist therapy or after bilateral orchiectomy
Participants must have evidence of PSMA-positive disease as seen on a AAA517 or piflufolastat F 18 PET/CT scan at baseline as determined by Blinded Independent Central Review (BICR) based on the methodology proposed in the Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE) (Eiber et al 2018). Participants with M1 disease only on PSMA PET scan are allowed to participate
Participants must have a negative conventional imaging for M1 disease.
PSA Doubling Time (PSADT) of ≤ 10 months
Participants must have adequate organ functions: bone marrow reserve, hepatic & renal
Key Exclusion criteria
Prior or present evidence of metastatic disease as assessed by CT/MRI locally for soft tissue disease and whole-body radionuclide bone scan for bone disease. Exception: Participants with soft tissue pelvic disease may be eligible (e.g., participants with enlarged lymph nodes below the aortic bifurcation (N1) are eligible if the short axis of the largest lymph node is <20 mm)
Unmanageable concurrent bladder outflow obstruction or urinary incontinence. Note: participants with bladder outflow obstruction or urinary incontinence, which is manageable with best available standard of care (incl. pads, drainage) are allowed
Active clinically significant cardiac disease; history of seizure or condition that may pre-dispose to seizure which may require treatment with surgery or radiation therapy
Prior therapy with: second generation anti-androgens (e.g., enzalutamide, apalutamide and darolutamide); CYP17 inhibitors (e.g., abiraterone acetate, orteronel, galeterone, ketoconazole; radiopharmaceutical agents (e.g., Strontium-89), PSMA-targeted radioligand therapy; immunotherapy (e.g., sipuleucel-T); chemotherapy, except if administered in the adjuvant/neoadjuvant setting, completed > 2 years before randomization; any other investigational agents for CRPC; use of estrogens, 5-α reductase inhibitors (finasteride, dutasteride), other steroidogenesis inhibitors (aminoglutethimide) or first-generation anti-androgens (bicalutamide, flutamide, nilutamide, cyproterone) within 28 days before randomization; radiation therapy (external beam radiation therapy [EBRT] and brachytherapy within 28 days before randomization
Other concurrent cytotoxicity chemotherapy, immunotherapy, radioligand therapy, poly adenosine diphosphate-ribose polymerase (PARP) inhibitor, biological therapy or investigational therapy
Other protocol-defined inclusion/exclusion criteria may apply.
