CEACAM5 Radiotheranostics: A Targeted Strategy for PSMA-Negative, Neuroendocrine Prostate Cancer

For prostate cancer patients with low expression of PSMA or with neuroendocrine prostate cancer or NEPC (a population growing in size precisely because better treatments are forcing tumors to adapt), a new preclinical study offers a credible precision-targeted strategy: a radiotheranostic pair built on the CEACAM5 surface antigen that produced complete tumor responses in every […]

ctDNA and Fragmentomics Reveal New Predictors of Survival in 177 Lu-PSMA–617 mCRPC

Metastatic castration-resistant prostate cancer (mCRPC) remains one of the most challenging stages of prostate cancer, marked by poor prognosis and limited durable treatment options. The radioligand therapy 177Lu-PSMA-617 (Pluvicto) has emerged as a significant advance, demonstrating an overall survival benefit in selected patients. However, clinical responses vary widely, highlighting an urgent need for biomarkers that […]

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 […]

²²⁵Ac‑RAX104: A Next‑Generation PSMA Alpha Radioligand for Advanced Prostate Cancer

RAX104 is a small molecule ligand designed specifically to target PSMA, the protein that is highly expressed on the surface of prostate cancer cells. When labeled with ²²⁵Ac, it forms a radioligand that combines the physical advantages of actinium‑225 (high linear energy transfer and a 10‑day half‑life) with a ligand engineered for better tumor retention. […]

UPLIFT Trial: Abemaciclib Safely Boosts PSMA for Better Radioligand Therapy in Advanced Prostate Cancer

The UPLIFT trial is a phase 1/2 study testing a new combo for metastatic castrate-resistant prostate cancer. Researchers at the University of California, San Francisco, designed this trial to boost the power of 177Lu-PSMA-617, a targeted radiation drug called a radioligand therapy. That drug latches onto PSMA, a protein stamped all over prostate cancer cells, […]

Phase 1 PAnTHa Trial: mCRPC First Data

²²⁵Ac‑PSMA‑Trillium (BAY3563254) is an experimental treatment that delivers targeted alpha radiation to prostate cancer cells. It combines a highly selective PSMA‑binding molecule with an albumin‑binding domain that helps it stay in the bloodstream longer and reach tumors more effectively. The radioactive component, actinium‑225, is attached using a stable Macropa chelator to increase safety and stability. […]

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 […]

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 […]

UPDATE: SECuRE Trial Phase 2 Shows 67% PSA50 Response in Heavily Pre-Treated mCRPC

The latest interim update from the SECuRE trial reinforces the impression that copper‑67 PSMA targeting is emerging as a credible contender in the mCRPC radioligand space, with consistent PSA responses and a clean safety profile in a small but challenging population. The Safety Review Committee has endorsed continuation of the Phase 2 cohort expansion without […]

PSMA-1-DOTA: A New Ligand to Make Prostate Cancer Radioligand Therapy More Targeted

PSMA-targeted radioligand therapy (RLT) has transformed treatment for end-stage prostate cancer, offering strong tumor control in patients who have exhausted other options. However, these therapies frequently cause severe salivary gland damage, leading to debilitating dry mouth that often forces patients to stop treatment early. To overcome this, researchers at Case Western Reserve University developed PSMA-1-DOTA, […]
