This is a three-part study evaluating the safety and efficacy of a PSMA-directed radioantibody (rosopatamab tetraxetan, conjugated to either In-111 or Ac-225). Part 1 will consist of one administration of In-111-rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants then will be enrolled into either Part 2 (Dose Optimization) or Part 3 (Dose Escalation and Expansion) depending on their prior treatment history. Participants qualifying for Part 2 will be randomized to receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle (dose administration on Day 1 and Day 15) at either 45 or 60 kBq/Kg. Participants qualifying for Part 3 must have received prior Lu-177-PSMA-radioligand therapy and will receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle at 45, 55, or 60 kBq/Kg. Dose limiting toxicities (DLTs) will be monitored in Part 3 to determine the recommended phase 2 dose (RP2D), and the study may enroll additional participants to be treated with the RP2D dose level. Participants enrolled into any part will attend study visits which will include blood samples, electrocardiogram (ECG), radiographic imaging, and physical examinations along with other assessments.
Phase 1: The objective of the Phase 1 part of the clinical trial is to verify safety and tolerability (dose-limiting toxicity \[DLT\], maximum tolerated dose \[MTD\]) of a single 3.7 Giga-Becquerel (GBq) dose with the potential for one dose level de-escalation to 2.775 GBq if necessary, to determine the recommended \[177Lu\]Ludotadipep dose for use in the Phase 2a part of the trial. Phase 2a: The objective of the Phase 2a part of the trial is to evaluate safety and efficacy for repeated administration of the recommended \[177Lu\]Ludotadipep dose. The Recommended Phase 2 dose (RP2D) will be based on the study results from the Phase 1 trial in South Korea upon consultation with the FDA.
Single-arm, prospective registry study assessing changes in acute patient-reported urinary (GU) and gastrointestinal (GI) quality of life at the 24-month post-treatment time point following magnetic resonance imaging (MRI)-guided or computed tomography (CT)-guided stereotactic body radiotherapy (SBRT) delivered to the prostate bed +/- pelvic lymph nodes. The decision to offer an adaptive treatment will be at the clinician's discretion.
The purpose of this study is to evaluate the safety and tolerability of Lutetium-177-PSMA-617 (PLUVICTO) in patients with metastatic castration-resistant prostate cancer (mCRPC) and extensive bone metastases, which appear as a "super scan" pattern on a bone scan. Pluvicto is FDA-approved, but patients with super scan bone scans were previously excluded from the VISION clinical trial, leaving a knowledge gap. The study will enroll up to 30 men with metastatic castration-resistant prostate cancer, with an initial dosing approach that differs from the standard dose. The safety and tolerability of PLUVICTO will be evaluated in this study, with a focus on identifying the optimal dose for this population. This study addresses an important gap in understanding how Pluvicto performs in mCRPC patients with super scan findings.
This is a multicenter, Phase 1/2 clinical trial to evaluate DCC-3084 alone or in combination with other cancer therapies in participants with advanced cancers. Module A will enroll participants with advanced/metastatic solid tumors. Additional modules exploring other cancers may be added to the master protocol at a later date. Each module will be conducted in 2 parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion).
FIH, Phase 1, open-label, multi centre study of CB307, a trispecific Humabody® T-cell enhancer, in patients with advanced and/or metastatic PSMA+ solid tumours to assess safety and tolerability to determine MTD and preliminary RP2D.In addition this study will assess the safety and efficacy of CB307 when given in combination with pembrolizumab (KEYTRUDA®) in patients with metastatic PSMA+ castration-resistant cancer
