Phase 1/2 PARTHENON Trial: AZD4956 Targets HRD in Advanced Prostate Cancer

The PARTHENON trial tests AZD4956, an experimental oral drug that blocks SMARCA2, a protein helping cancer cells rearrange their DNA to keep growing. In tumors already “weak” at fixing DNA damage due to homologous recombination deficiency (HRD), shutting down SMARCA2 creates a double hit: cells can’t remodel chromatin or repair errors, leading to collapse. This […]

Phase 1 Trial for SYS6043: A New Antibody-Drug Conjugate Targeting B7-H3

SYS6043 is a new type of antibody-drug conjugate, or ADC. It zeroes in on B7-H3, a protein that is expresse by advanced tumors but almost not at all on healthy cells. The antibody part sticks to B7-H3, gets pulled inside the cancer cell, and releases a topoisomerase I inhibitor that breaks the cell’s DNA and […]

HER2 FPBMC Therapy in the AM006 Phase 1/2 Trial for Metastatic Prostate Cancer

The AM006 clinical trial, tests HER2 FPBMC anti-CD3 x anti-HER2 bispecific antibody (HER2Bi)-armed activated T cells, in patients with HER2-positive metastatic prostate and breast cancer. For prostate cancer patients, this targets the 20-30% of metastatic cases overexpressing HER2, offering a fresh immune-based option after standard therapies fail. HER2 FPBMC starts with a simple blood draw […]

Capivasertib + Abiraterone in CAPItello-281: Promising rPFS in PTEN-Deficient mHSPC

The phase 3 trial CAPItello-281, has delivered compelling evidence that capivasertib combined with abiraterone could transform treatment for PTEN-deficient metastatic hormone-sensitive prostate cancer (mHSPC), a subtype affecting a substantial portion of advanced cases. In this double-blind study, 1012 patients with PTEN deficiency (defined rigorously as 90% or more viable malignant cells showing no cytoplasmic staining […]

Final PEACE-3 Trial Data: Radium-223 + Enzalutamide Extends Survival by 5.6 Months in Bone mCRPC.

Radium-223 plus enzalutamide significantly boosts survival for men with metastatic castration-resistant prostate cancer (mCRPC) and bone metastases, according to final results from the Phase 3 PEACE-3 trial  presented at ASCO GU 2026. In this study of 446 patients with at least two bone metastases who were asymptomatic or only mildly symptomatic, adding six infusions of […]

Phase 2 Trial of Cu-64 SAR-bisPSMA Doubles Prostate Lesion Detection

64Cu-SAR-bisPSMA represents a next-generation PSMA-targeted PET imaging agent for prostate cancer, demonstrating superior lesion and patient detection in the Phase 2 Co-PSMA trial announced in February 2026. In this head-to-head study of 50 patients with biochemical recurrence (BCR) after prostatectomy (PSA 0.2-0.75 ng/mL), Cu-64 SAR-bisPSMA more than doubled mean lesions per patient at 1.26 (63 […]

Igermetostat Plus Enzalutamide Delivers Promising rPFS in Post-Abiraterone mCRPC

Igermetostat (XNW5004), a selective EZH2 inhibitor, pairs effectively with enzalutamide in metastatic castration-resistant prostate cancer after prior novel hormone therapy, based on phase 1b/2 results. EZH2 inhibition reverses enzalutamide resistance through epigenetic changes in castration-resistant prostate cancer models. The study endpoints focused on recommended phase 2 dose, safety, and radiographic progression-free survival. ​Eighty-four patients enrolled […]

UPLIFT Trial: Abemaciclib Safely Boosts PSMA for Better Radioligand Therapy in Advanced Prostate Cancer

The UPLIFT trial is a phase 1/2 study testing a new combo for metastatic castrate-resistant prostate cancer. Researchers at the University of California, San Francisco, designed this trial to boost the power of 177Lu-PSMA-617, a targeted radiation drug called a radioligand therapy. That drug latches onto PSMA, a protein stamped all over prostate cancer cells, […]

Early Results From a Phase 1 Trial for MRT-2359 Plus Enzalutamide in mCRPC

MRT-2359 is a daily pill that destroys certain cancer-driving proteins, including the androgen receptor (AR), MYC, and Cyclin D1, by blocking a key step in how cells read genetic instructions. This approach targets metastatic castration-resistant prostate cancer (mCRPC), where AR mutations in the ligand-binding domain (LBD) allow tumors to grow despite hormone-blocking drugs like enzalutamide. […]

Phase 1 PAnTHa Trial: mCRPC First Data

²²⁵Ac‑PSMA‑Trillium (BAY3563254) is an experimental treatment that delivers targeted alpha radiation to prostate cancer cells. It combines a highly selective PSMA‑binding molecule with an albumin‑binding domain that helps it stay in the bloodstream longer and reach tumors more effectively. The radioactive component, actinium‑225, is attached using a stable Macropa chelator to increase safety and stability. […]
