UPDATE: VIR-5500 Extended into mHSPC

VIR-5500 expanded into mHSPC in April 2026, when it announced the first patient had been dosed in the Phase 1 dose-expansion cohorts. VIR-5500 is being studied in late-line mCRPC as monotherapy and, importantly for this expansion, in combination with an androgen receptor pathway inhibitor in early-line mCRPC and mHSPC. The move was built on earlier […]

UPDATE: SL-28 Phase 1/2 Trial Started To Recruit in Advanced Solid Tumors

A very interesting Phase 1/2 trial of SL‑28 has started enrolling up to 60 patients with advanced solid tumours at The Southern Oncology Clinical Research Unit (SOCRU). Although the study is open to a broad range of solid cancers, it is particularly noteworthy for prostate cancer because a published case report described a complete response […]

Phase 1 Trial of SHY-ONC6, a Proteasome-Modulating Therapy in Solid Tumors (Including mCRPC)

SHY-ONC6 is now entering a Phase 1 first-in-human clinical study in patients with advanced or metastatic solid tumors. The trial is open-label and multicenter, and its main goals are to assess safety, tolerability, pharmacokinetics, and early signs of anti-tumor activity in people whose disease has progressed on standard therapy or who cannot tolerate it. SHY-ONC6 […]

UPDATE: AO-252 Demonstrates 80% Clinical Benefit Rate as Development Shifts to Expansion Phase

AO-252, a first-in-class TACC3 inhibitor, continues to show early clinical promise in advanced solid tumours, with recent updates highlighting both improved efficacy through optimized dosing and a new formulation designed to enhance drug exposure. Interim data from an ongoing Phase 1/2 trial demonstrated a clear dosing-dependent effect. Transitioning from once-daily (QD) to twice-daily (BID) administration […]

Soon to Start Phase 1/2 Trial: CRISPR-Edited Tregs Enter the Clinic for Solid Tumors

CRG-150, a CRISPR-edited regulatory T cell therapy has entered first-in-human testing for solid tumors, marking an unusual and potentially important step in oncology. The program is aimed at metastatic breast and prostate cancers, two settings where treatment options remain limited once disease becomes advanced. What makes this approach different is the cell type being used. […]

RIPCORD Phase 1 Trial: Interim PSMA PET–Guided Adaptive Radiotherapy in Metastatic Castration-Sensitive Prostate Cancer

RIPCORD is a UT Southwestern phase 1 trial testing a simple but important idea: can PSMA PET be used during treatment to decide how much metastasis-directed radiotherapy a patient actually needs? It focuses on men with poly-metastatic castration-sensitive prostate cancer and uses interim 68Ga-PSMA-11 PET to adapt stereotactic ablative radiotherapy (SABR) rather than giving every […]

GRPR-Targeted Radioligand Therapy in Prostate Cancer: The A9-0631 and A9-0642 Trial

A new first-in-human study is testing whether GRPR-targeted radiopharmaceuticals can extend precision oncology beyond the PSMA and SSTR frameworks. The trial combines two therapeutic agents, 177Lu-A9-0631 and 225Ac-A9-0642, with GRPR imaging using 68Ga-A9-6217 or low-dose 177Lu-A9-0631 in patients with GRPR-positive solid tumors. GRPR, or gastrin-releasing peptide receptor, is an appealing target because it is overexpressed […]

Bavdegalutamide Plus Abiraterone in Metastatic Prostate Cancer: Phase Ib Safety and Activity Results

Bavdegalutamide (ARV-110) is an oral androgen receptor degrader designed to address resistance to androgen-receptor–targeted therapy in metastatic prostate cancer. In this phase 1b study, it was combined with abiraterone in patients whose disease was progressing on abiraterone, with the goal of testing safety, pharmacokinetics, and early signs of antitumor activity. The trial enrolled 45 patients, […]

Another Phase 1/2 Trial With SX-682, Combined With Docetaxel This Time

SX-682 is moving into a new clinical context. After an ongoing trial in prostate cancer with androgen receptor pathway inhibitors such as apalutamide and enzalutamide, the CXCR1/2 inhibitor is now being studied with docetaxel in recurrent/metastatic head and neck squamous cell carcinoma, salivary gland carcinoma, and advanced prostate cancer. That matters because docetaxel is not […]

Phase 1 Trial for a New PSMA Radioligand 177Lu‑PSMA‑VG01

177Lu‑PSMA‑VG01 is a next‑generation, small‑molecule PSMA‑targeting radiopharmaceutical designed to refine what 177Lu‑PSMA‑617 (Pluvicto) has already achieved. It uses a high‑affinity ligand to deliver the beta‑emitter lutetium‑177 directly to PSMA‑expressing tumor cells, aiming for greater tumor dosing with less exposure of healthy tissue. A new phase 1 trial is testing its dosimetry and side effects on […]
