GVV858: A New Approach to Castration-Resistant Prostate Cancer Phase 1/2 Trial

GVV858 is a CDK2 inhibitor designed to block this escape route. Instead of adding another hormone therapy when resistance develops, it targets the cell cycle machinery that CCNE1-amplified tumors depend on. The drug works on the molecular brakes that control when cells divide, rather than trying to manipulate hormone levels further. CCNE1 amplification allows cancer […]

UPDATE: AB-3028 Reaches Clinical Trial Stage for mCRPC

AB-3028, programmable circuit T cell therapy for metastatic castration-resistant prostate cancer (mCRPC), has now advanced into a Phase 1/2 clinical trial. This marks the first clinical testing of this highly engineered, logic‑gated CAR-T platform in prostate cancer, moving it from a purely preclinical concept into human evaluation. The trial should start recruiting in January 2026. […]

Researchers Explain How Prostate Cancer Can Survive Androgen Blockade

A research from Sylvester Comprehensive Cancer Center and the University of Miami Miller School of Medicine shows that prostate cancer cells can synthesize androgens through an alternative pathway that does not rely on CYP17A1, the enzyme at the core of virtually all modern androgen deprivation strategies. Instead of flowing through the classical cholesterol → pregnenolone […]

UPDATE: AO-252, a New First-in-Class Brain-Penetrating TACC3 Inhibitor for Prostate Cancer

A new drug called AO-252, an oral inhibitor of TACC3, is now in phase 1 trials specifically testing it against prostate cancer among other solid tumors. It smartly blocks TACC3’s key partnerships with proteins like KIFC1, clathrin, BRCA1, and others, triggering mitotic disasters and halting growth in both lab models and early patients (some saw tumors […]

Newsletter 50/2025

LAST WEEK TODAY! A summary of what was published on ProstateWarriors.com during the past week Hi fellow warriors! I’m back again with some new research. Not even dinners with friends can stop me from publishing! Stay strong and fight on! As usual, we also have a podcast if you prefer to listen to the newsletter, you can find […]

GSK5764227: An Antibody-Drug Conjugate Targeting B7-H3 Enters Phase 1/2 Trial

GSK5764227 represents a promising advancement in treating metastatic castration-resistant prostate cancer (mCRPC). This antibody-drug conjugate targets B7-H3, a protein overexpressed on prostate cancer cells, delivering a topoisomerase I inhibitor payload directly to tumors while minimizing damage to healthy tissues. Early data from broader solid tumor studies show the drug’s monotherapy potential, with objective response rates […]

MHB048C: A New PSMA-Targeted Therapy for Advanced Solid Tumors

MHB048C is an investigational antibody–drug conjugate designed to target prostate‑specific membrane antigen (PSMA) on tumor cells and selectively deliver a DNA topoisomerase I–inhibiting cytotoxic payload. By combining a PSMA‑directed antibody with a potent payload, the drug aims to exploit the high and relatively restricted expression of this surface antigen in advanced prostate cancer and in […]

Logic-gated DARPins, a Promising Advancement in Immune Therapy for Solid Tumors

Logic-gated DARPins are a promising new tool in cancer treatment that could make immunotherapy safer and more effective for hard-to-treat solid tumors. They work by only turning on immune cells called T cells when two specific markers are found together on cancer cells, preventing dangerous overactivation in healthy parts of the body.​ What makes them […]

CONVERT‑HB1: a Phase 2 Trial About Prostate Directed Treatment After Systemic Treatment in mHSPC

CONVERT‑HB1 trial addresses a long‑standing uncertainty in metastatic hormone‑sensitive prostate cancer: whether aggressively treating the primary prostate tumor adds meaningful benefit for patients who already have high‑volume metastatic disease and are receiving modern intensified systemic therapy. For years, data from studies like STAMPEDE and HORRAD suggested that local treatment to the prostate might help men […]

UPDATE: ProstACT Global Phase 3 Trial for TLX591 Dosed The First Patient

ProstACT Global is a pivotal randomized Phase 3 study testing the PSMA-targeted radiopharmaceutical TLX591 (lutetium‑177 rosopatamab tetraxetan) in metastatic castration‑resistant prostate cancer. The trial has just moved into its randomized expansion phase, with the first patient in this part dosed at a specialized prostate cancer center in Melbourne, marking a key transition from safety/dosimetry work […]
