A New Immune‑Engaging ADC Platform: STEAP1‑Targeted Vandortuzumab–Exatecan

Antibody–drug conjugates (ADCs) have transformed therapy in several malignancies, but in advanced prostate cancer they have mostly been evaluated for direct tumor cytotoxicity, with little attention to immune mechanisms that might underpin durable responses. A recent study introduces a new STEAP1‑targeted ADC platform built on vandortuzumab, an antibody directed at six‑transmembrane epithelial antigen of the […]

Three Targets Beyond PSMA in Prostate Cancer Radioligand Therapy

Radioligand therapy transformed advanced prostate cancer care with PSMA targeting. Now experts eye options for PSMA-resistant or low-expression cases. At APCCC 2026, Dr. Ken Herrmann named ACP3, B7-H3, and STEAP1/STEAP2 as top priorities. These could reach patients (outside clinical trials) in four to five years. ACP3, or prostatic acid phosphatase, binds tighter than PSMA in […]

AKY-2519: Phase 1b Trial Targets B7-H3 in Metastatic Prostate Cancer

AKY-2519, a miniprotein radioconjugate targeting B7-H3, has entered a Phase 1b clinical trial in patients with metastatic castration-resistant prostate cancer (mCRPC). The open-label study enrolls both PLUVICTO-naïve and PLUVICTO-experienced patients at multiple U.S. radioligand therapy centers, evaluating three dose levels in each cohort before expanding at selected doses. Preliminary safety and efficacy data from this […]

Newsletter 18/2026

LAST WEEK TODAY! A summary of what was published on ProstateWarriors.com during the past week Hello fellow warriors! This week I selected the studies I’ll be following during the ASCO 2026 annual meeting, which will take place at the end of the month. There are some very interesting things! But for now, let’s start with this week’s […]

GX-BP1: Targeting SOX2 to Prevent Resistance in mCRPC

GX-BP1, a bioPROTAC-based SOX2 degrader, selectively targets SOX2, an undruggable protein, for ubiquitin-proteasome elimination, overcoming limitations of prior inhibition strategies. In preclinical models, GX-BP1 monotherapy delivered approximately 70% tumor growth inhibition, while combinations with agents like carboplatin/paclitaxel achieved 87-96% inhibition and near-complete tumor suppression at optimal doses. Notably, GX-BP1 paired with osimertinib eradicated cancer stem […]

TLX597-Tx Shows Early Promise in a Phase 2 PSMA Trial for Prostate Cancer

TLX597-Tx (177Lu-DOTA-HYNIC-panPSMA) is emerging as a next-generation PSMA-targeted radioligand therapy designed to deliver radiation more precisely to prostate cancer cells while limiting exposure to healthy organs. New data from the OPTIMAL-PSMA trial suggest that the drug may achieve strong tumor uptake with relatively low dose to the salivary glands and kidneys, two of the main […]

Phase 2 ARTEMIS-003 Trial: HS-20093 for mCRPC

HS-20093  has received Breakthrough Therapy designation from China’s National Medical Products Administration for metastatic castration-resistant prostate cancer. The designation covers patients previously treated with novel endocrine therapy and taxane-based chemotherapy, a setting where later-line treatment options remain limited. HS-20093 is a B7-H3-targeted antibody-drug conjugate designed to bind tumor cells expressing B7-H3 and deliver a cytotoxic […]

B7-H3 Emerges as Prime Target for Prostate Cancer Across All Stages

A 2026 study published in Clinical Cancer Research has pinpointed B7-H3 as a standout therapeutic target for prostate cancer, offering hope against the disease’s toughest forms. The work analyzed tissue from prostate cancer patients across the full spectrum, from hormone-sensitive and castration-resistant to neuroendocrine and “double-negative” subtypes, revealing B7-H3’s consistent, broad expression. This uniformity stands […]
