New Phase 2 trial for JNJ-101556143 aka HLD-0915 in mCRPC / mAPMR Prostate Cancer

A new phase 2 trial will test JNJ-101556143, also known as HLD-0915, in men with metastatic prostate cancer that has become resistant to androgen-pathway treatment. The study plans to enrol about 100 patients and will evaluate whether the drug can produce objective tumour responses, making this a clear step beyond the earlier dose-finding programme. JNJ-101556143 […]

JUR-003 Enters Phase 1 Trial in Metastatic Prostate Cancer

A new first-in-human phase 1 trial, has been posted for JUR-003 in metastatic prostate cancer. The study plans to enrol up to 210 patients and includes dose-escalation and dose-expansion cohorts in mCRPC, metastatic hormone-sensitive prostate cancer (mHSPC) and oligometastatic disease. JUR-003 will be given intravenously, with the initial goals of defining safety, pharmacokinetics and a […]

ENV105 Phase 2 Trial for mCRPC: Can Prostate Cancer Be Made Sensitive to Hormone Therapy Again?

We already discussed ENV105 (carotuximab) in a previous ProstateWarriors article, when the safety lead-in of its phase 2 trial in metastatic castration-resistant prostate cancer was completed. Since then, the programme has produced its first meaningful efficacy signal, making it worth revisiting. ENV105 targets CD105, a protein that appears to become more active as prostate cancer […]

Terbinafine: An Old Antifungal Enters a Phase 2 Prostate Cancer Trial

An inexpensive antifungal drug that has been used for decades is now being tested as a prostate cancer treatment. The phase 2 TerbinaPro trial is evaluating terbinafine in men whose prostate cancer has returned biochemically after previous treatment. Behind this unusual drug-repurposing trial lies an intriguing discovery about how prostate cancer produces cholesterol. The target […]

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 […]
