EXS74539: A New LSD1 Inhibitor for Hard-to-Treat Solid Tumors, Including Prostate Cancer

EXS74539, also called REC-4539, is an experimental cancer drug designed to block LSD1, a protein that helps some cancer cells grow and survive even when standard treatments fail. It is being tested in a phase 1 trial on people with selected solid tumors, including small-cell lung cancer, prostate cancer, ovarian cancer and others. This early-stage […]

TSL2109: A Novel Dual-Target Cancer Drug for Resistant Prostate Cancer

TSL2109 is an experimental oral cancer drug being studied in people with advanced solid tumors, especially metastatic castration-resistant prostate cancer (aka androgen pathway modulation resistant prostate cancer, or APMR, God save us!) and advanced hormone receptor–positive, HER2-negative breast cancer. It is designed to hit two important targets at once, CDK4/6 and DYRK2, which may help […]

PRINCE Trial Final Results: Lu-PSMA-617 + Pembrolizumab Shows Deep Responses in Advanced mCRPC

The PRINCE trial has delivered final results showing promise for treating metastatic castration-resistant prostate cancer (mCRPC) with the combination of 177Lu-PSMA-617 (Pluvicto) and pembrolizumab. Published in The Lancet Oncology on April 1, 2026 , this single-arm, phase 1b/2 trial enrolled 37 heavily pretreated men (median age 72, 73% prior docetaxel, 100% prior AR inhibitors) who […]

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 […]

UPDATE: MRT-2359 in Metastatic Castration-Resistant Prostate Cancer

MRT‑2359 is an investigational, orally bioavailable molecular‑glue degrader targeting GSPT1, a protein involved in translation termination. We talked about this new molecule in this article just one month ago, we already have some good news. In prostate cancer it is being studied in combination with androgen‑receptor (AR)‑axis inhibitors, particularly in metastatic castration‑resistant prostate cancer (mCRPC), […]

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 […]

Enolen Implant Cuts Localized Prostate Tumor Volume by 84% in Early Study

Enolen is an investigational anti‑androgen implant designed to deliver enzalutamide directly inside the prostate, aiming to shrink localized prostate tumors while minimizing systemic exposure to the drug. In data from a National Cancer Institute–led phase‑1 study, the device produced an 84% reduction in measurable tumor volume on MRI over roughly five weeks in men scheduled […]

Estrogen‑Based Androgen Suppression Plus ARSI in Prostate Cancer: A Phase 2 Quality‑of‑Life Trial

A new phase 2 EQUIP trial is comparing two different ways of delivering androgen‑suppressive hormone therapy in men with newly diagnosed or recurrent metastatic hormone‑sensitive prostate cancer, focusing on whether transdermal estrogen patches can improve quality of life compared with standard luteinizing hormone‑releasing hormone (LHRH) analogues. The study is designed around two randomized cohorts, each […]
