Phase 1 Trial for SNV1521 PARP1 Inhibitor in mCRPC aka mAPMR Prostate Cancer

A next-generation PARP inhibitor called SNV1521 is showing early signs of activity in advanced prostate cancer, while potentially causing less bone-marrow toxicity than existing PARP drugs. SNV1521 is an oral drug designed to selectively inhibit PARP1 while largely sparing PARP2. Current PARP inhibitors such as olaparib inhibit both proteins, and suppression of PARP2 is thought […]

ctDNA Blood Test May Identify High-Risk mHSPC Before Treatment Begins

A blood test taken before starting treatment could help identify men with metastatic hormone-sensitive prostate cancer (mHSPC) who are at greater risk of developing treatment resistance early. We have already discussed the importance of ctDNA after treatment in a previous article, but this new study looks at its potential value even before treatment begins. A […]

Radium-223 May Reduce Immune Activity in Prostate Cancer Bone Metastases

A new prospective clinical study suggests that radium-223 may change the immune environment of prostate cancer bone metastases in a way that makes subsequent immunotherapy less effective. The study included 28 men with metastatic castration-resistant prostate cancer (mCRPC) and predominantly bone metastases. Patients received radium-223, with six injections planned at four-week intervals. Researchers wanted to […]

Phase 1 Trial: JANX007 Plus JANX013 Combo in mCRPC / mAPMR

A newly registered phase 1 trial is taking an interesting approach to one of the limitations of T-cell engagers in prostate cancer: rather than simply trying to make them more powerful, it will test whether a second immune signal can make their activity more durable. The trial will evaluate JANX007 together with the new drug […]

Soon to be Phase 1 for ICP-B381, a New Bispecific Antibody-Drug Conjugate for mCPRC

A new antibody-drug conjugate has received clearance to enter clinical trials in China with a double strategy for prostate cancer: instead of targeting PSMA or STEAP1, ICP-B381 targets both. The experimental bispecific ADC combines a humanised antibody recognising PSMA and STEAP1 with a proprietary cytotoxic payload connected through an irreversible linker. Both proteins are strongly […]

Phase 1/2 Trial Results for Tinengotinib (TT-00420) in mCRPC

Tinengotinib (TT-00420), a multikinase inhibitor with a distinctive target profile, is showing early signals in metastatic castration‑resistant prostate cancer (mCRPC), a setting where options after modern androgen‑receptor pathway inhibitors and taxanes remain limited. Results from a US‑based, multicenter phase 1/2 trial, published in Clinical Cancer Research, reported an objective response rate of 33.3% in a […]

STAMINA: Supervised Exercise and Dietary Advice Cut ADT-Related Decline in Prostate Cancer

A multicentre, randomised trial published in The Lancet Oncology shows that a supervised, behaviourally supported lifestyle programme can measurably blunt the adverse effects of androgen deprivation therapy (ADT) for prostate cancer. Called STAMINA, the study enrolled 700 men on ADT across 15 NHS trusts in England and randomly assigned them in a 5:4 ratio to […]

Phase 1 Trial: IL‑18–Armored STEAP1 CAR T Cells for Metastatic Castration‑Resistant Prostate Cancer

IL‑18–armored STEAP1 CAR T cells represent a biologically rational, early‑clinical strategy that combines a well‑validated prostate‑cancer target with next‑generation cytokine armoring designed to overcome the hostile tumour microenvironment and antigen heterogeneity that have limited earlier immunotherapy efforts. STEAP1 (six‑transmembrane epithelial antigen of the prostate 1) was first identified in advanced prostate cancer and is now […]

Phase 3 Trial Tests a New B7-H3 Strategy in Advanced Prostate Cancer

A new phase 3 clinical trial is preparing to evaluate risvutatug rezetecan, or Ris-Rez or GSK5764227, in men with metastatic castration-resistant prostate cancer (mCRPC), an advanced form of prostate cancer that continues to progress despite androgen-deprivation treatment. The study, called EMBOLD Prostate-302, will compare this experimental therapy with best supportive or standard care, potentially including the […]

Phase 1 Trial: 177Lu-DTPA-SC16.56 in Neuroendocrine Prostate Cancer

Neuroendocrine prostate cancer (NEPC) is a highly aggressive, treatment-resistant form of prostate cancer that emerges after androgen-deprivation therapies fail, leaving few effective options. Memorial Sloan Kettering Cancer Center is now running a Phase I trial testing a radiolabeled antibody called 177Lu-DTPA-SC16.56 in patients with progressive, chemotherapy-relapsed neuroendocrine prostate and lung cancers. DLL3 is the reason […]
