Phase 3 PSMAddition Trial Reports Positive Outcomes for mHSPC

Results from the PSMAddition trial were published in a phase 3 setting and showed several clear numbers worth noting. The trial compared standard double hormone-based treatment alone (ADT + ARPI) versus the same treatment plus a PSMA-targeted radioligand therapy (Pluvicto), in men with metastatic hormone-sensitive prostate cancer.The biggest headline was a 58% lower risk of […]

Newsletter 20/2026

LAST WEEK TODAY! A summary of what was published on ProstateWarriors.com during the past week Hello fellow warriors! As you can probably tell, every now and then I blow off steam by generating images with AI! This week we have quite a few updates on the clinical trial front, as well as some interesting insights from preclinical […]

ARASEC Trial Validates Darolutamide Plus ADT in Metastatic Hormone-Sensitive Prostate Cancer

The ARASEC trial, offers compelling evidence for darolutamide combined with androgen deprivation therapy as a treatment option for men with metastatic hormone-sensitive prostate cancer. This Phase 2 study tackled a challenging ethical dilemma in modern clinical trial design: how to evaluate a new treatment when randomizing patients to receive only standard ADT would be considered […]

Telmisartan: A Familiar Blood Pressure Pill with New Potential in Cancer Therapy

Telmisartan, a widely used blood pressure drug, has shown unexpected promise as a booster for cancer treatment. Preclinical research indicates that when telmisartan is combined with the PARP inhibitor olaparib, cancer cells accumulate more DNA damage and become more vulnerable to treatment, even if they do not carry the usual BRCA‑type DNA repair defects that […]

Targeted Alpha Therapy Plus PARP Blockade: AZD2265 plus AZD9574 for Advanced Prostate Cancer

There is a new flexible trial for men with metastatic prostate cancer that has stopped responding to hormone therapy. Phase 1/2 PROSPECTOR trial tests three options: a PSMA‑targeted radioactive drug (AZD2265), the same drug combined with a PARP1 inhibitor (AZD9574), and standard docetaxel chemotherapy. The first part of the trial finds safe dose levels and […]

Phase 1 Trial: GTB-5550, Another B7-H3 NK-targeted Therapy for mCRPC

GTB-5550 has begun Phase 1 clinical testing in solid tumors, marking the first patient dosing in a dose-escalation basket study. The trial is starting with prostate cancer, a setting where B7-H3 is reportedly highly expressed and where treatment options remain limited in the metastatic castration-resistant stage. The therapy is being delivered subcutaneously, which is notable […]

Phase 1 Trial: INR731 for mCRPC

INR731 is an oral, investigational anticancer drug now entering first‑in‑human testing for men with metastatic castration‑resistant prostate cancer (mCRPC). It is being evaluated in a global, open‑label Phase 1 study with the primary goal of defining its safety, tolerability, pharmacokinetics, pharmacodynamics, and a recommended dose for further development, rather than demonstrating efficacy at this stage. […]

Phase 1/2 Trial for GDC‑1261 in Advanced Prostate Cancer

GDC‑1261 is a new study drug being tested in men with advanced or metastatic prostate cancer in a first‑in‑human Phase 1/2 trial. The public description of the study states that the main goals are to evaluate the safety profile, pharmacokinetics, and preliminary anti‑tumor activity of GDC‑1261 and to identify a recommended dose and dosing schedule […]

DNA‑barcoded Gold Nanoparticles that Deliver Therapy Directly to Cancer Cell Mitochondria.

Cancer drugs often fail not because they are weak, but because they never reach the exact place they are supposed to act, all the way down to the tiny structures inside tumour cells. Researchers at the National University of Singapore have developed a new way to search for nanoparticles that can carry treatment directly to […]

Phase 1/2 Update: Concurrent Enzalutamide–Cabazitaxel Produces Durable PFS Signal in mCRPC

The updated Phase 1/2 data for concurrent enzalutamide plus cabazitaxel in chemo‑naïve mCRPC show deep biochemical responses and a promising signal for progression‑free outcomes, but the dataset remains hypothesis‑generating. In a multi‑institutional single‑arm trial of enzalutamide with cabazitaxel (plus prednisone), 35 patients were included in the efficacy analysis with a median follow‑up of 23.7 months; […]
