Phase 3 Trial Tests a New B7-H3 Strategy in Advanced Prostate Cancer

A new phase 3 clinical trial is preparing to evaluate risvutatug rezetecan, or Ris-Rez or GSK5764227, in men with metastatic castration-resistant prostate cancer (mCRPC), an advanced form of prostate cancer that continues to progress despite androgen-deprivation treatment. The study, called EMBOLD Prostate-302, will compare this experimental therapy with best supportive or standard care, potentially including the […]

Soon to be Phase 1 Trial: AK157D1 a New B7‑H3–Targeted ADC in Advanced Prostate Cancer

The investigational B7‑H3–targeting antibody–drug conjugate AK157D1, recently cleared for a Phase I trial in advanced solid tumors, is especially compelling from a prostate cancer perspective because B7‑H3 (CD276) is one of the most uniformly expressed and biologically aggressive surface targets across the full disease continuum, from hormone‑sensitive to castration‑resistant and neuroendocrine phenotypes. Unlike PSMA, which […]

B7-H3: A Continuum-Wide, AR-Repressed Anchor for Combinatorial Prostate Cancer Therapy

A landmark 2026 study in Clinical Cancer Research reframes surface-target therapy in advanced prostate cancer by placing B7-H3 (CD276) at the center of a continuum-wide strategy. Integrating the JHU-PANORAMA single-cell atlas (~1M cells, 213 patients) with patient-derived xenografts, metastatic rapid-autopsy tissues, and mechanistic cell-line work, the authors show that B7-H3 is the most uniformly expressed […]

B7-H3 ADC YL201 Delivers Encouraging Results in Advanced mCRPC

YL201, a B7-H3–targeting antibody–drug conjugate, is showing notable activity in advanced metastatic castration-resistant prostate cancer (mCRPC), including patients who have progressed after androgen receptor–targeted therapy and chemotherapy. In a phase 2 study of 82 heavily pretreated patients, the drug delivered a confirmed PSA50 response rate of 38.5%, an objective response rate of 29.5%, and a […]

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 […]

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 […]

B7‑H3 Expression Shapes Prognosis Differently Across Prostate Cancer Stages

A new observational study of more than 8,000 prostate tumors shows that B7‑H3 (CD276) expression helps shape prognosis and could open new paths for targeted therapies. Researchers analyzed 8,157 prostate cancer samples with matched DNA and RNA data, stratifying them by tissue site, hormone‑sensitivity status, and self‑reported race, then examined how B7‑H3 levels related to […]

Phase 1 Trial: Dual-Target ADC IDE034 Targets B7-H3/PTK7 in Prostate Cancer

A promising new bispecific antibody-drug conjugate (ADC) known as IDE034 is entering early clinical testing in patients with advanced solid tumors, including prostate cancer, marking a potential step forward in precision oncology. This Phase 1a/1b trial, which began dosing its first patient in February 2026, targets tumors expressing both B7-H3 and PTK7, two surface proteins […]

NEOK001: A New Bispecific Antibody–Drug Conjugate for Advanced Prostate Cancer

A promising new experimental drug called NEOK001 (also known as ABL206) is emerging as a potential therapy for advanced cancers that express two specific proteins on their surface: B7‑H3 and ROR1. Among these cancers, prostate cancer is one of the tumor types where early data already show signs of activity, making NEOK001 a candidate of […]
