UPDATE: Phase 1 Trial for OP-3136 in mCRPC Started Recruiting

The first-in-human phase 1 trial of OP-3136, a novel orally bioavailable KAT6A/B inhibitor for solid tumors, started recruiting, with the prostate cancer cohort focusing on men with metastatic castration-resistant prostate cancer (mCRPC). This represents a significant expansion of OP-3136 beyond its initial focus on estrogen receptor-positive breast cancer, following encouraging preclinical data presented at AACR […]

Alliance A222001 Phase 2 Trial: Oxybutynin Looks Promising for Hot Flashes in Men Under ADT

The Alliance A222001 study, published in the Journal of Clinical Oncology in January 2026, found that oxybutynin, a drug typically used to treat overactive bladder, significantly reduces hot flashes in men receiving androgen-deprivation therapy (ADT), with improvements occurring within the first week of treatment and sustained throughout the study period. The findings could reshape how […]

Phase 1/2 JASPER Trial: Ruxolitinib Plus Enzalutamide for mCRPC

The JASPER trial is a phase 1/2 study launching from the University of Michigan, takes a fundamentally different approach to castration-resistant prostate cancer by targeting the molecular machinery driving cancer plasticity from the start: the JAK/STAT inflammatory signaling axis. Understanding why this strategy makes biological sense requires stepping into what we now know about how […]

ANDROMEDA Trial: Alpha vs. Beta PSMA Therapy

The ANDROMEDA phase 2 trial represents an advancement in managing recurrent oligometastatic prostate cancer by directly pitting alpha-emitting 225Ac-PSMA-617 against the established beta-emitting 177Lu-PSMA-617 (Pluvicto), both combined with stereotactic body radiotherapy (SBRT). This head-to-head comparison stems from the need to address limitations in current therapies for patients whose cancer returns in 1-5 detectable spots on […]

Phase 1 Trial for DCC-2812 in Metastatic Castration-Resistant Prostate Cancer

DCC-2812 is a new oral drug designed to fight advanced cancers, especially in the urinary and reproductive systems like kidney, bladder, and prostate cancers. It works by turning on a special stress response inside cancer cells that pushes them past their breaking point, leading to cell death. Cancer cells live in harsh environments with low […]

Preliminary Data From a Phase 1/2 Trial of PDS01ADC Plus Docetaxel in mCRPC

Preliminary results from an ongoing phase 1/2 trial combining docetaxel with the tumor-targeting IL-12 immunocytokine PDS01ADC  (aka M9241) indicate promising early activity in patients with metastatic castration-resistant prostate cancer (mCRPC). The single-arm study, presented at the American Association for Cancer Research special conference on prostate cancer research, enrolled 16 patients with progressive mCRPC, most of […]

New Phase 3 Trial For BNT324 in Metastatic Castration-Resistant Prostate Cancer

BNT324 (DB-1311) is rapidly emerging as one of the most promising new agents in metastatic castration-resistant prostate cancer (mCRPC), with a data package that is unusually strong for a first-in-class B7-H3–targeting antibody–drug conjugate and now compelling enough to justify a head‑to‑head Phase 3 trial against docetaxel. The reason it has attracted so much attention is […]

Actinium‑225 NTSR1‑Targeted Radiopharmaceutical SKL35501

SKL35501 is an emerging radiopharmaceutical therapy that embodies much of what “next‑generation oncology” is supposed to mean: precise targeting, potent cell kill, and a built‑in companion diagnostic strategy. In January 2026, the US FDA cleared SKL35501 and its imaging partner SKL35502 for a phase 1 Investigational New Drug (IND). SKL35501 originated as FL‑091, a small‑molecule […]

ARREST Trial: Precision Radiation Boosts to Fix 177Lu-PSMA’s 50% Failure Rate

ARREST trial could change mCRPC treatment by solving 177Lu-PSMA’s biggest limitation: up to 50% of patients get little benefit despite FDA approval and proven survival gains. The simple idea? Add targeted external beam radiation boosts to the tumors that radioligand therapy misses, creating a hybrid approach that could cut skeletal complications dramatically. Current 177Lu-PSMA therapy […]

Phase 3 Trial For Opevesostat A CYP11A1 Inhibitor in mCRPC

Opevesostat, a first-in-class CYP11A1 inhibitor, blocks the first step of steroid hormone production, eliminating all ligands that activate mutant androgen receptors in metastatic castration-resistant prostate cancer (mCRPC). The Phase 3 MK-5684-004 aka OMAHA-004 trial tests it against standard next-generation hormonal agents (NHAs, like abiraterone, enzalutamide, …) switching in 1,500 patients progressed on one prior NHA, […]
