Targeted Alpha Therapy Plus PARP Blockade: AZD2265 plus AZD9574 for Advanced Prostate Cancer

There is a new flexible trial for men with metastatic prostate cancer that has stopped responding to hormone therapy. Phase 1/2 PROSPECTOR trial tests three options: a PSMA‑targeted radioactive drug (AZD2265), the same drug combined with a PARP1 inhibitor (AZD9574), and standard docetaxel chemotherapy. The first part of the trial finds safe dose levels and […]

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 […]

EvoPAR-PR01: Saruparib (AZD5305) Phase III Trial in Metastatic Castration-Sensitive Prostate Cancer

Saruparib (AZD5305), a next-generation PARP1-selective inhibitor, represents a promising evolution in prostate cancer therapy, particularly for metastatic castration-sensitive disease (mCSPC), through the ongoing phase III EvoPAR-PR01 trial. Unlike first-generation PARP inhibitors (PARPi) such as olaparib that target both PARP1 and PARP2, saruparib specifically inhibits and traps PARP1 on DNA damage sites, sparing PARP2 to potentially […]

SPR1020: a Promising PARP1-Selective Inhibitor in Advanced Solid Tumors (Including mCRPC)

A  first-in-human Phase 1/2 trial of SPR1020, a highly selective PARP1 inhibitor, dosed its inaugural patient, igniting hope for patients with advanced solid tumors harboring DNA repair deficiencies. This open-label, multicenter study employs a classic 3+3 dose-escalation design to pinpoint the recommended Phase II dose or maximum tolerated dose, transitioning seamlessly into expansion cohorts tailored […]

ANDROMEDA: Phase 1/2 Trial of AZD9750 AR Degrader in Metastatic Prostate Cancer

The ANDROMEDA trial, a first-in-human Phase 1/2 study, is evaluating AZD9750, a novel androgen receptor (AR) PROTAC, in men with metastatic castration-resistant prostate cancer (mCRPC). PROTACs represent a paradigm shift in targeted therapy: unlike traditional AR inhibitors that merely block the receptor’s activity, AZD9750 recruits cellular machinery to completely degrade the AR protein, potentially overcoming […]
