UPDATE: Phase 1 Trial for RAD 402 Dosed the First Patient

Following our previous article, we are pleased to report that patient dosing has commenced in this trial. First patient has been dosed in this Phase 1 dose-escalation trial evaluating RAD 402, an anti-KLK3 (PSA) monoclonal antibody radiolabeled with Terbium-161 (Tb-161), in patients with advanced prostate cancer previously treated with standard therapies. Following our past article, […]

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 […]

New Xaluritamig (AMG 509) Monotherapy Phase 1 Trial for mCRPC

Xaluritamig (AMG 509) represents a promising new immunotherapy option for men with metastatic castration-resistant prostate cancer, or mCRPC, through this  new Phase 1 trial. The study aims to evaluate the safety profile of xaluritamig administered as monotherapy (plus ADT, as usual) at a specific proposed regimen in adult male participants whose cancer has progressed despite […]

Soon to Be Phase 1 Trial: FX‑111, A Selective ARon Degrader with the Potential to Rethink Androgen Deprivation in Prostate Cancer

A novel approach to targeting androgen receptor signaling in prostate cancer is emerging with FX‑111, an experimental degrader that selectively removes the hormone‑bound, transcriptionally active form of the receptor known as ARon. In metastatic castration‑resistant prostate cancer (mCRPC), the androgen receptor remains a central driver in the vast majority of cases, yet resistance to current […]

GLR2037: A First‑in‑Human AR‑Targeted PROTAC Enters Phase 1 Trials in Advanced Prostate Cancer

A new investigational agent code‑named GLR2037 has entered early clinical development as a first‑in‑human phase 1 study in patients with advanced prostate cancer, representing a significant step in the evolution of androgen receptor–directed therapies. GLR2037 is an androgen receptor (AR)–targeting proteolysis‑targeting chimera (PROTAC), designed not merely to inhibit the AR but to promote its ubiquitin‑proteasome–mediated […]

P‑PSMA‑101 CAR‑T Therapy in Advanced Prostate Cancer: Early Results from a Phase 1 Trial

P‑PSMA‑101 is an experimental CAR‑T cell therapy being tested in men with metastatic castration‑resistant prostate cancer (mCRPC) who have already received multiple standard treatments (up to 10 before enrollment). In the phase 1 trial, 33 men with heavily pretreated mCRPC received P‑PSMA‑101, an autologous PSMA‑targeted CAR‑T product enriched in stem‑cell‑like memory T cells and engineered […]

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 […]

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 […]
