Phase 1 Study of BPX-601: A Controlled Immune Therapy for Advanced Prostate Cancer

A new clinical trial has recently begun for a promising but complex type of cancer treatment called BPX-601, designed specifically for men dealing with advanced prostate cancer that has stopped responding to traditional therapies. This therapy is a form of CAR T-cell treatment, which means doctors take a patient’s own immune cells, reprogram them in […]

Double-Masked PSMA-TCE JANX014 Enters Phase 1 for mCRPC

A novel double-masked T-cell engager targeting prostate-specific membrane antigen (PSMA), called JANX014, has entered phase 1 testing in patients with metastatic castration-resistant prostate cancer (mCRPC). The first-in-human, open-label, multicenter trial, which dosed its initial participant in mid-April 2026, evaluates safety, tolerability, pharmacokinetics, pharmacodynamics, and early antitumor activity through ascending intravenous doses administered as monotherapy to […]

Phase 1/2 RAISIC‑1 Trial: PTT‑4256 in Advanced Solid Tumors

PTT‑4256 is an emerging first‑in‑class small‑molecule inhibitor of GPR65, a proton‑sensing G‑protein‑coupled receptor selectively expressed on immune cells within the acidic tumour microenvironment. It is being evaluated in the RAISIC‑1 trial, a modular, open‑label, phase 1/2 study in patients with advanced solid tumours designed to assess safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy. The trial’s […]

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 […]

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 […]

Phase 1 225Ac-J591 Trial: Strong Activity in Advanced Prostate Cancer, with Improved Outcomes Using a Fractionated Dosing Approach

225Ac-J591 (Actinium-225 rosopatamab tetraxetan) uses a radioactive particle linked to an antibody that targets PSMA, a protein found on prostate cancer cells, and it is being studied in a phase 1 clinical trial. Unlike more commonly used PSMA treatments that rely on small molecules, this approach uses an antibody, which behaves differently in the body. […]

Astatine-211 PSMA-5: Scalable Alpha Therapy for Refractory Prostate Cancer

211AtPSMA-5 emerges as a promising targeted alpha therapy for metastatic castration-resistant prostate cancer, particularly in patients who have exhausted standard treatments like androgen receptor pathway inhibitors, docetaxel, and cabazitaxel. This approach leverages astatine-211, a cyclotron-produced alpha emitter generated by bombarding abundant bismuth targets with alpha beams. The compound’s design mirrors established PSMA ligands such as […]

EXS74539: A New LSD1 Inhibitor for Hard-to-Treat Solid Tumors, Including Prostate Cancer

EXS74539, also called REC-4539, is an experimental cancer drug designed to block LSD1, a protein that helps some cancer cells grow and survive even when standard treatments fail. It is being tested in a phase 1 trial on people with selected solid tumors, including small-cell lung cancer, prostate cancer, ovarian cancer and others. This early-stage […]
