New drug combo aims to fight spread of prostate cancer
NCT ID NCT07140900
First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This early-phase trial is testing a new immunotherapy drug called xaluritamig combined with standard hormone therapies (darolutamide or abiraterone) in 60 men with metastatic hormone-sensitive prostate cancer. The main goal is to check safety and tolerability, while also looking at how well the combination controls the cancer. The study is currently recruiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- xaluritamig (a type of immunotherapy) combined with darolutamide or abiraterone (hormone-blocking drugs)
- What this could lead to
- If it works, this could lead to a more effective treatment option for men with metastatic hormone-sensitive prostate cancer.
- What could go wrong
- This is an early Phase 1b trial with only 60 participants, focused on safety. It is too soon to know if the combination will be effective or have manageable side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants must have histological, pathological, and/or cytological confirmation of adenocarcinoma of the prostate. Mixed histologies (eg, adenocarcinoma with neuroendocrine component) are not permitted. * Participants must have at the time of diagnosis: * De novo (synchronous) mHSPC, defined as metastatic disease with no prior diagnosis of localized prostate cancer, AND started ADT (LHRH agonist/antagonist or orchiectomy) with or without ARPI (defined as abiraterone OR darolutamide) as SOC, first treatment with ADT should be no longer than 12 weeks before screening. Prior docetaxel treatment is not permitted. * Participants must have at the time of diagnosis: * High-volume metastatic disease defined as presence of visceral metastasis or metastases, and/or ≥ 4 bone metastases with at least one outside of the vertebral column and pelvis. * Documented metastatic disease either by a positive bone scan, or for soft tissue or visceral metastases, either by contrast enhanced abdominal/pelvic/chest computed tomography (CT) or magnetic resonance imaging (MRI) scan. * No documented PSA progression following the initial PSA nadir after starting ADT. Exclusion Criteria: * Prior history of central nervous system (CNS) metastases. Note: Participants with asymptomatic and clinically stable dural metastases are eligible. * Unresolved toxicities from prior anti-tumor therapy (excluding those related to ongoing ADT and ARPI) not having resolved to Common Terminology Criteria for Adverse events (CTCAE) version 5.0 grade 1 or baseline, with the exception of alopecia or toxicities that are stable and well-controlled AND there is an agreement to allow inclusion by both the investigator and the sponsor. * Autoimmune disease requiring systemic immunosuppression within the past 2 years. * Participant with symptoms and/or clinical signs and/or radiographic signs that indicate an acute and/or uncontrolled active or systemic infection within 7 days prior to the first dose of study treatment. * Prior six-transmembrane epithelial antigen of the prostate 1 (STEAP1)-targeted therapy. * Prior radioligand therapy (RLT), poly-adenosine diphosphate ribose polymerase (PARP) inhibitor, cytotoxic chemotherapy, aminoglutethimide or ketoconazole for prostate cancer, or any prior systemic biologic therapy, including immunotherapy for prostate cancer. * Prior enzalutamide or apalutamide within 15 days prior to enrolment. * Requirement for chronic systemic corticosteroid therapy (prednisone dose greater than 10 mg per day or local equivalent) or any other immunosuppressive therapies (including anti TNFα therapies) unless stopped (with adequate tapering) within 7 days prior to dosing. * Prior radiotherapy to all metastatic sites of disease. Radiotherapy to some sites of metastatic disease for palliation will be permitted.
