TTX-MC138 Takes Aim at a Master MicroRNA

Most cancer drugs attack something on the tumour cell: a receptor, an enzyme, a signalling pathway or a surface protein. TTX-MC138 takes a different approach. It is designed to inhibit microRNA-10b (miR-10b), a small regulatory RNA strongly associated with invasion, metastatic progression and survival of metastatic tumour cells. The idea is unusually ambitious: rather than […]

Phase 2/3 Trial For 68Ga-DOTA-RM2: GRPR-Targeted PET Could Open the Door to a New Theranostic Platform

PSMA has transformed prostate cancer imaging and radioligand therapy, but it is not the only useful target on prostate cancer cells. A new pivotal trial, SPARROW, is now testing 68Ga-DOTA-RM2, a PET tracer that targets the gastrin-releasing peptide receptor, or GRPR, in men with prostate cancer. The study is designed to determine how accurately GRPR-PET […]

Eight-Year PACE-A Results Support SBRT for Localised Prostate Cancer

For men with localised low- or intermediate-risk prostate cancer who need treatment, one of the biggest decisions is whether to choose surgery or radiotherapy. The phase 3 PACE-A trial is the first randomised study to directly compare modern prostatectomy with stereotactic body radiotherapy (SBRT) delivered in just five treatments. New long-term results presented at ASTRO […]

Can We Predict Deep PSA Response Before Treatment Starts? NADIR Validated in ARCHES

A new analysis of the phase 3 ARCHES trial suggests that a simple clinical model may help predict which men with metastatic hormone-sensitive prostate cancer are most likely to achieve a very deep PSA response after starting treatment with an androgen-receptor pathway inhibitor. The model, called NADIR, was designed to estimate the probability of reaching […]

Carboplatin Shows Activity in HRR-Altered Metastatic Prostate Cancer

Platinum chemotherapy is not usually considered a standard targeted treatment for metastatic prostate cancer, but the phase 2 CIPHER trial suggests that carboplatin may have meaningful activity in men with mCRPC carrying homologous recombination repair (HRR) mutations. The study enrolled 39 patients with HRR-altered mCRPC who had already received at least one androgen-receptor pathway inhibitor […]

Neuromedin U: A New Way Neuroendocrine Prostate Cancer May Hide From the Immune System

Neuroendocrine prostate cancer is one of the most aggressive forms of the disease and remains particularly difficult to treat. A new Oncogene study has identified a possible mechanism that helps these tumours suppress the immune response, centred on a molecule called Neuromedin U, or NMU. In mouse models of neuroendocrine prostate cancer, the researchers found […]

A “Plug-and-Play” CAR-T That Could Be Updated as Cancer Changes

CAR-T therapy has transformed some blood cancers, but solid tumors remain much more difficult. One major problem is tumor heterogeneity: not every cancer cell expresses the same target, and tumours can change over time. A new preclinical study published in Cancer Immunology Research describes a way to make CAR-T cells more adaptable. The researchers created […]

B7-H3 May Be Doing More Than Marking Prostate Cancer

B7-H3 has become one of the most interesting targets in advanced prostate cancer, especially for antibody-drug conjugates and other targeted treatments. A new Cancer Discovery study suggests that B7-H3 may not simply sit on the surface of tumour cells: it may actively help the cancer suppress the immune system and resist treatment. The researchers found […]

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 […]
