Phase 2 Trial for 61Cu-NU101 vs 18F-Piflufolastat in Metastatic Prostate Cancer

61Cu-NU101 is a new PSMA-targeted PET/SPECT tracer for prostate cancer that showed promise in phase 1, detecting more lesions than 18F-piflufolastat (Pylarify) in half of the 8 patients studied, with lower background uptake and no side effects. The key advantage is its 3.3-hour half-life, compared to 68 minutes for 68Ga-PSMA-11 and 109 minutes for 18F-piflufolastat. […]

UPDATE: Memantine for Neuroendocrine Prostate Cancer, Early Efficacy Signals

Prostate cancer can become harder to treat when it changes from the usual adenocarcinoma form into neuroendocrine prostate cancer, or NEPC. A recent study suggests that this transition may begin earlier than expected, during an intermediate phase when the cells are still partly prostate-like but are already starting to acquire neuroendocrine features. A central finding […]

Confirmed Efficacy of Rucaparib in BRCA-Mutated mCRPC

Rucaparib continues to strengthen its position in BRCA-mutated metastatic castration-resistant prostate cancer (mCRPC), an advanced form of prostate cancer that progresses despite hormonal therapy, with TRITON3 trial confirming not only its efficacy but also a predictable and manageable safety profile. In this phase 3 study of chemotherapy-naïve patients progressing after one prior androgen receptor pathway […]

Early Phase 1 Trial of GRPR-Targeted Theranostic DOTA-STR-17126

A first-in-human imaging trial of DOTA-STR-17126 just started in Australia. It is an open-label, single-arm early phase 1 study enrolling up to 20 adults with advanced or metastatic prostate or breast cancer who have exhausted standard treatments. The trial uses a theranostic approach. Participants receive gallium-68 DOTA-STR-17126 for PET imaging to detect tumors expressing the […]

Phase 2 Trial of GV20-0251 With Anti-PD-1 Therapy in mCRPC

GV20-0251 is an experimental antibody that blocks a new immune brake called IGSF8, and this phase 2 study tests it together with anti-PD-1 drugs in people with advanced solid tumors that no longer respond to standard treatment. The goal is to restore early innate immune signaling so checkpoint therapy works better in resistant cancers. From […]

Zanzalintinib After Pluvicto in Chemo‑Naïve mCRPC

Zanzalintinib is being tested after Pluvicto (177Lu-PSMA-617) in metastatic castration‑resistant prostate cancer (mCRPC) because it targets several escape routes tumors use once they have survived PSMA‑directed radioligand therapy and prolonged AR pathway blockade. Pluvicto delivers beta radiation to PSMA‑expressing cells, inducing DNA damage and tumor cell death, but progression still occurs and is often driven […]

UPDATE: ABBV-969 Shows Very Promising rFPS in mCRPC

ABBV-969 is a dual-target antibody-drug conjugate targeting PSMA and STEAP1, data about its radiographic progression-free survival data have just been released, confirming a median rPFS of approximately 15 months in heavily pretreated metastatic castration-resistant prostate cancer. The study demonstrates a signal far exceeding the 4- to 5-month rPFS historically seen with cabazitaxel in the same […]

CD46 ImmunoPET in mCRPC: A New Theranostic Axis Beyond PSMA

CD46 is a cell‑surface protein that stays highly expressed in aggressive, late‑stage prostate cancer, including PSMA‑low, AR‑negative and neuroendocrine variants. That means CD46 immunoPET can still “see” and quantify disease that PSMA PET misses, and can guide CD46‑targeted therapies in exactly those PSMA‑low/negative patients who respond poorly to PSMA‑directed radioligand therapy. Using the human antibody […]

The PROTEUS Trial: Perioperative Apalutamide Shows Positive Results for Prostate Cancer

The PROTEUS phase 3 trial, published in the New England Journal of Medicine, shows that adding perioperative apalutamide to androgen-deprivation therapy significantly improves outcomes for men with high-risk localized or locally advanced prostate cancer undergoing radical prostatectomy. The international trial randomized 2,109 patients to six cycles of ADT plus apalutamide (240 mg daily) or ADT […]

VECTRA-01 Phase 3 Trial Tests Alpha-Emitting AZD2265 in PSMA-Positive mCRPC

A pivotal Phase 3 trial called VECTRA-01 has launched to evaluate AZD2265 (²²⁵Ac-PSMA-I&T), an alpha-emitting radioligand therapy targeting PSMA-positive metastatic castration-resistant prostate cancer. The study began in May 2026, enrolling approximately 670 participants across 90 global sites, with recruitment currently active at select locations. The trial’s primary objective is to demonstrate superiority over standard of […]
