Phase 1/2 Trial for AZD8359: a CD8-Biased T Cell Engager Targeting STEAP2 in m CRPC

Bispecific T cell engagers, while conceptually powerful, have carried a toxicity profile that constrains their clinical utility. AZD8359, a novel trispecific T cell engager now entering its first-in-human clinical trial, represents a thoughtful attempt to resolve that toxicity problem at the molecular engineering level, and its preclinical data are among the most compelling seen in this […]

UPDATE: Phase 1 Trial of HSK46575, a Novel CYP11A1 Inhibitor for Advanced Prostate Cancer

HSK46575, a novel CYP11A1 inhibitor designed to suppress the entire steroidogenesis pathway, continues to generate interest in advanced prostate cancer, with new early-phase clinical data providing a clearer picture of its activity and tolerability in patients. At the latest data cut-off, 27 patients with advanced prostate cancer had been treated across dose-escalation cohorts ranging from […]

ITRI-148: A Next-Generation AR Degrader Targeting Resistance at Its Core

A new experimental compound, ITRI-148, may represent a meaningful shift in how advanced prostate cancer is treated, particularly in patients who develop resistance to current androgen receptor (AR)-targeted therapies. Resistance to drugs like enzalutamide is frequently driven by AR splice variants such as AR-V7, which lack the ligand-binding domain (LBD) targeted by existing therapies, allowing […]

ProTCE-PSMA Pushes PSMA T-Cell Engagers Toward a Safer Therapeutic Window

A new generation of PSMA-targeted T-cell engagers is emerging with a clear goal: preserve the potency seen in hematologic malignancies while overcoming the safety and efficacy barriers that have limited success in solid tumors. A preclinical candidate, ProTCE-PSMA, presented ahead of IND filing in early 2026, illustrates how rapidly this field is evolving beyond first-generation […]

DLL3-Targeted ADC ZL-1310 Shows Early Promise in Neuroendocrine Carcinomas

Early-phase data from the ZL-1310-002 trial introduce a potentially important new therapeutic option for patients with advanced neuroendocrine carcinomas (NECs), a group of aggressive malignancies with very limited treatment options after platinum-based chemotherapy. Among these, neuroendocrine prostate cancer (NEPC) represents one of the most clinically challenging subtypes, characterized by rapid progression, resistance to androgen receptor–targeted […]

Early Results for ACE‑106 (ACE‑86225106): A Selective PARP1 Inhibitor for HRR‑Mutant Cancers

ACE‑106 (ACE‑86225106) is a highly selective PARP1 inhibitor designed to improve the therapeutic index compared with first‑generation pan‑PARP inhibitors, which broadly inhibit both PARP1 and PARP2 while causing substantial hematologic toxicity. The updated first‑in‑human data from the open‑label, dose‑escalation study show that ACE‑106 is well tolerated, with no dose‑limiting toxicities, no grade 4–5 treatment‑related adverse […]

Helicon Peptides: Degrading Active AR to Overcome Prostate Cancer Resistance

Current AR therapies like enzalutamide target the inactive, unliganded AR conformation (AROFF) by binding its androgen pocket, preventing activation but leaving already active, agonist-bound AR (ARON), the real driver of tumor transcription and proliferation, untouched. This allows resistant tumors to adapt through AR gene amplification, mutations in the ligand-binding domain, or alternative activation pathways, leading […]

ctDNA and Fragmentomics Reveal New Predictors of Survival in 177 Lu-PSMA–617 mCRPC

Metastatic castration-resistant prostate cancer (mCRPC) remains one of the most challenging stages of prostate cancer, marked by poor prognosis and limited durable treatment options. The radioligand therapy 177Lu-PSMA-617 (Pluvicto) has emerged as a significant advance, demonstrating an overall survival benefit in selected patients. However, clinical responses vary widely, highlighting an urgent need for biomarkers that […]
