EvoPAR-PR01: Saruparib (AZD5305) Phase III Trial in Metastatic Castration-Sensitive Prostate Cancer

/in , , /by

Saruparib (AZD5305), a next-generation PARP1-selective inhibitor, represents a promising evolution in prostate cancer therapy, particularly for metastatic castration-sensitive disease (mCSPC), through the ongoing phase III EvoPAR-PR01 trial. Unlike first-generation PARP inhibitors (PARPi) such as olaparib that target both PARP1 and PARP2, saruparib specifically inhibits and traps PARP1 on DNA damage sites, sparing PARP2 to potentially […]

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

/in , , /by

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

/in , , , , /by

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

/in , , , /by

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

/in , , /by

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

/in , , /by

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

/in , , , /by

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 […]
