PET-Guided Radiotherapy Shows Lasting Control of Recurrent Prostate Cancer

A new retrospective study with a 10-year follow-up suggests that some men with prostate cancer recurring only in lymph nodes may achieve prolonged disease control using PET-directed radiotherapy combined with temporary androgen deprivation therapy (ADT). The retrospective study included 93 men with hormone-sensitive prostate cancer that had returned in pelvic and/or para-aortic lymph nodes after […]

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 […]

Tracking Response and Resistance to Lu-177 Plus Immunotherapy

A new analysis of the PRINCE clinical trial suggests that combining blood-based ctDNA testing with PSMA PET could help identify which men with metastatic castration-resistant prostate cancer (mCRPC) are most likely to respond to Lu-177 PSMA plus immunotherapy. PRINCE was a multicentre Phase 1/2 trial involving 37 men with mCRPC. Patients received up to six […]

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 […]

CEA Emerges as a Potential Prognostic Marker for Lu-177 PSMA Therapy

A simple blood test normally associated with colorectal cancer could provide additional information about how men with metastatic castration-resistant prostate cancer fare after 177Lu-PSMA-617 therapy. A new prospective study of 142 patients found that elevated carcinoembryonic antigen (CEA) before treatment was independently associated with shorter progression-free and overall survival. The finding does not mean that […]

CRISPR Takes Another Step Forward

CRISPR can precisely alter DNA, but using it against cancer faces a fundamental problem: how do you deliver the genome-editing machinery to tumour cells without also editing healthy tissue? A newly published review proposes that aptamers, small synthetic DNA or RNA molecules capable of recognising specific cell-surface proteins, could provide part of the solution, guiding […]

A STEAP1 ADC That May Turn Tumour Killing Into an Immune Response

A newly published study has introduced an interesting variation on antibody-drug conjugates (ADCs) for advanced prostate cancer: instead of simply delivering a toxic payload to cancer cells, the treatment is designed to help the immune system recognise what remains. The experimental ADC targets STEAP1, a cell-surface protein highly expressed in prostate cancer and already being […]

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 […]
