Phase 1 225Ac-J591 Trial: Strong Activity in Advanced Prostate Cancer, with Improved Outcomes Using a Fractionated Dosing Approach

225Ac-J591 (Actinium-225 rosopatamab tetraxetan) uses a radioactive particle linked to an antibody that targets PSMA, a protein found on prostate cancer cells, and it is being studied in a phase 1 clinical trial. Unlike more commonly used PSMA treatments that rely on small molecules, this approach uses an antibody, which behaves differently in the body. […]

Astatine-211 PSMA-5: Scalable Alpha Therapy for Refractory Prostate Cancer

211AtPSMA-5 emerges as a promising targeted alpha therapy for metastatic castration-resistant prostate cancer, particularly in patients who have exhausted standard treatments like androgen receptor pathway inhibitors, docetaxel, and cabazitaxel. This approach leverages astatine-211, a cyclotron-produced alpha emitter generated by bombarding abundant bismuth targets with alpha beams. The compound’s design mirrors established PSMA ligands such as […]

Deutenzalutamide in mCRPC: Meaningful Benefit in the HC‑1119‑04 Trial

Nature reports the results of the HC‑1119‑04 trial, a randomized, multicenter, double‑blind, placebo‑controlled phase 3 study of deutenzalutamide (HC‑1119) in metastatic castration‑resistant prostate cancer (mCRPC) after treatment with abiraterone and docetaxel. The trial was conducted in China and enrolled 417 patients, with 276 randomized to deutenzalutamide 80 mg once daily and 141 to placebo. All […]

Darolutamide Monotherapy in ARAMON Trial: 52-Week Results in Non-Metastatic or Oligometastatic CSPC

A new study called ARAMON shows promising results for using darolutamide alone to treat non-metastatic or oligometastatic castration-sensitive prostate cancer (CSPC), as known as androgen pathway modulator sensitive (APMS), in men who have biochemical recurrence after surgery or radiation. This phase 2 trial enrolled 23 evaluable patients with PSA ≥0.2 ng/mL post-prostatectomy or ≥2 ng/mL […]

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 […]
