Phase 1 Trial GTB-5550, a Immunotherapy Targeting B7-H3 in Solid Tumors (Including mCRPC)

/in , , /by

A new immunotherapy called GTB-5550 targeting B7-H3 on cancer cells has received FDA clearance for its first human trial (expected to start in the first half of 2026), offering fresh hope particularly for advanced prostate cancer patients exhausted by standard treatments. GTB-5550 is a TriKE molecule that binds natural killer (NK) cells from the immune […]

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 […]

AlphaGenome: a New AI Tool to Understand DNA

/in /by

Imagine you have a long string of DNA code, a million letters long. A new AI tool called AlphaGenome reads that code and predicts exactly what it does. It tells you how active genes are, how DNA folds open or closed, where proteins stick to it, and even how far-apart parts of DNA touch each […]

Nanotech Advancement: Relief from Prostate Cancer Bone Pain on the Horizon

/in , /by

A promising study published this month in Science Advances introduces a promising “neuroimmunotherapy” nanocarrier called LipoNCs@pGSDMB, designed precisely for bone metastases like those in prostate cancer. This tiny, smart drug delivery system activates only in the high-oxidative-stress environment of bone tumors, fusing directly with cancer cell membranes to release its payload straight into the cell’s […]
