UPDATE: TheraPb Reports 11.2-Month Median rPFS With 212Pb-ADVC001

Updated results from the TheraPb phase 1 trial, presented at ESMO 2026, provide longer-term follow-up for ²¹²Pb-ADVC001, an experimental PSMA-targeted alpha radioligand therapy for metastatic castration-resistant prostate cancer (mCRPC). The study enrolled 22 heavily pretreated patients across different dose levels and treatment schedules. With an additional 12 months of observation and a median follow-up of […]

Phase 1 ProTACT: Actinium-225 FL-020 Shows Early Activity in Advanced Prostate Cancer

New results show preliminary antitumor activity for 225Ac-FL-020, an investigational PSMA-targeted alpha radioligand, in patients with metastatic castration-resistant prostate cancer (mCRPC). The findings come from ProTACT, an ongoing first-in-human phase 1 trial evaluating the safety, dosing, and preliminary efficacy of FL-020 in patients previously treated with androgen receptor pathway inhibitors and taxane chemotherapy, unless chemotherapy […]

Phase 1 Trial: Astatine-211 PSMA-5 Shows Strong Early Responses in First-in-Human Prostate Cancer Trial

Encouraging results suggest that 211At-PSMA-5, an experimental alpha-emitting radioligand targeting PSMA, may offer a promising new treatment approach for patients with metastatic castration-resistant prostate cancer (mCRPC). The findings come from a first-in-human phase 1 study involving 15 patients whose disease had progressed following androgen receptor pathway inhibitors and taxane-based chemotherapy. Unlike established PSMA-targeted radioligand therapy […]

Phase 2 Trial: DLL3 PET Reveals Tumor Heterogeneity in Neuroendocrine Prostate Cancer

New findings suggest that an experimental PET imaging technique targeting DLL3 could help identify neuroendocrine prostate cancer (NEPC) lesions and reveal important differences between metastases within the same patient. Neuroendocrine prostate cancer is an aggressive form of the disease that can emerge following prolonged treatment with androgen receptor-targeted therapies. These tumors frequently show reduced PSMA […]

UPDATE: ²²⁵Ac-LNC1011 Achieves 86.7% PSA50 Response in Early mCRPC Study

New results presented at EANM 2026 provide further evidence of the preliminary clinical activity of ²²⁵Ac-LNC1011, an experimental PSMA-targeted alpha radioligand therapy for metastatic castration-resistant prostate cancer (mCRPC). We have previously discussed this therapy in this post. Following the initial results, the new prospective study includes 15 patients previously treated with androgen receptor pathway inhibitors […]

New PSMA Radiohybrid Combines PET Imaging With Alpha Therapy

A new preclinical study published in the Journal of Nuclear Medicine has investigated rhPSMA-10.1, a radiohybrid compound designed to combine PET imaging with targeted alpha therapy for prostate cancer. The approach uses two closely related versions of the same PSMA-targeting molecule: ¹⁸F/La-rhPSMA-10.1 for PET imaging and ²²⁵Ac-rhPSMA-10.1 for treatment. Their similar chemical properties could allow […]

UPDATE: LUNAR Trial Follow-Up Strengthens Case for Earlier PSMA Radioligand Therapy

Longer follow-up from the randomized phase 2 LUNAR trial suggests that PSMA-targeted radioligand therapy may do more than simply delay progression when used early in men with oligorecurrent hormone-sensitive prostate cancer. LUNAR enrolled 92 men whose prostate cancer had returned after previous treatment, with one to five metastases visible on PSMA PET/CT. Importantly, patients were […]

Phase 3 Trial for 177Lu-ludotadipep Radioligand Therapy for mCRPC

A new phase 3 trial is testing 177Lu-ludotadipep (177Lu-FC705 or, simply, FC705), an experimental PSMA-targeted radioligand therapy for metastatic castration-resistant prostate cancer (mCRPC). Unlike 177Lu-PSMA-617 (Pluvicto), ludotadipep includes an albumin-binding component designed to keep the radioligand in circulation longer and increase radiation delivery to PSMA-positive tumours. Earlier studies suggest that this strategy may allow substantial […]

ATM-Altered Prostate Cancer May Be Especially Sensitive to Lu-177-PSMA

A new study suggests that ATM alterations could identify a subgroup of metastatic castration-resistant prostate cancer particularly likely to benefit from 177Lu-PSMA-617 (Pluvicto). The retrospective analysis included 205 men with mCRPC treated with Lu-177-PSMA-617 between 2022 and 2026, all of whom had next-generation DNA sequencing available. ATM alterations were present in 12.7% of patients and […]

UPDATE: Seven Complete Responses in a 19-Patient Cohort of 67Cu-SAR-bisPSMA Trial for mCRPC

A small but encouraging clinical dataset suggests that 67Cu-SAR-bisPSMA may produce substantial anti-tumour activity in patients with metastatic castration-resistant prostate cancer (mCRPC) who have exhausted multiple treatment options. The findings come from the SECuRE clinical trial, in which 19 participants received treatment with 67Cu-SAR-bisPSMA at an 8 GBq dose. Despite the advanced disease setting, treatment […]
