New hope for tough prostate cancer: drug combo trial launches
NCT ID NCT07047118
First seen Jun 24, 2026 · Last updated Sep 18, 2026 · Updated 8 times
Summary
This Phase II trial tests a new drug, JSB462 (luxdegalutamide), combined with a radioactive therapy (Pluvicto) in 138 men with PSMA-positive metastatic castration-resistant prostate cancer that has progressed after prior treatments. The study aims to see if the combination works better than Pluvicto alone and to find the best dose for future studies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JSB462 (luxdegalutamide) and lutetium (177Lu) vipivotide tetraxetan (Pluvicto)
- What this could lead to
- If successful, this combination could offer a new treatment option for men with advanced prostate cancer that has stopped responding to standard therapies.
- What could go wrong
- This is a Phase II trial with only 138 participants, so results are preliminary. The combination may not improve outcomes over Pluvicto alone and could cause additional side effects.

Key Inclusion Criteria: * Adult male participants with histologically and/or cytologically confirmed adenocarcinoma of the prostate. Participants with mixed histology (neuroendocrine) are not eligible. * An Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) grade ≤2. * At least 1 bone or visceral metastatic lesion present on baseline CT, MRI, or bone scan imaging obtained ≤28 days prior to initiation of study treatment. * Participants must be \[68Ga\]Ga-PSMA-11 PET/CT scan positive and eligible as determined by the sponsor's central reader. * Participant must have prior exposure to at least one second generation ARPI in the metastatic/advanced setting. * Previous treatment with a maximum of 2 taxane regimens is allowed. * Participants eligible for PARPi and/or immune checkpoint inhibitor (per local testing and according to investigator's judgement) are eligible to participate if they have previous exposure to this(these) therapy(ies).
