Combining BCL-2 Inhibitors With Androgen Blockade May Prevent Castration Resistance

Researchers at Roswell Park Comprehensive Cancer Center have identified a critical vulnerability in how prostate cancers escape standard hormonal therapy. The study reveals that when androgen receptor signaling is suppressed by ADT or AR pathway inhibitors, cancer cells compensate by ramping up BCL-2, an anti-apoptotic protein that helps them survive treatment. The findings suggest that […]

UPDATE: OncoACP3‑DOTA, First‑in‑Human Therapeutic Signal Beyond PSMA

OncoACP3‑DOTA is a small‑molecule ligand directed at prostatic acid phosphatase (ACP3, also historically called PAP), a membrane‑bound phosphatase that is highly specific to the prostate, with only weak expression in normal tissues such as kidney. Preclinical work showed that ACP3 is retained in many prostate tumors, including lesions with low or absent PSMA expression, and […]

CRISPR’s New Kill‑Switch: Targeting Cancer Cells by Their RNA Signature

A new CRISPR system recently published in Nature could change how we think about selectively eliminating cancer cells without touching healthy tissue. Instead of using the classic Cas9 to edit DNA, researchers have repurposed Cas12a2, an enzyme that first binds to a specific RNA sequence and then unleashes a wave of DNA destruction across the […]

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 […]

Genetic Maps of Blood Proteins Open New Paths for Cancer Drug Repurposing

A huge international team has just completed the largest study ever on how our genes control the levels of proteins circulating in our blood. The work, led by researchers at Queen Mary University of London and the Berlin Institute of Health, brings together data from more than 78,000 people across 38 cohorts worldwide and has […]

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 […]

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 […]
