Discovery of Androgen Metabolism Enhancing Androgen Receptor Antagonists for the Treatment of Castration-Resistant prostate Cancer
(EORTC-NCI-AACR 2024)
- "To provide sustained treatment options, next-generation ARSIs with unique mechanisms of action, including our AR N terminus domain (NTD) binding degrader (SARD), ONCT-534, and PROTAC ARV-110 are in clinical development...Transcriptomic analysis with a combination of 19B and enzalutamide showed regulation of pathways that are distinct from that of enzalutamide. The results indicate that UGT2B enzyme expression and function are critical for the efficacy of AR antagonists. We have also discovered a new class of AR antagonist that sustainedly induces UGT2Bs and synergizes with clinical AR antagonists to inhibit PCa and CRPC growth."

Oncternal Therapeutics Announces Updated Safety and Efficacy Data for Phase 1/2 Study of ONCT-534 for the Treatment of R/R Metastatic Castration-Resistant Prostate Cancer
(GlobeNewswire)
- P1/2 | N=21 | NCT05917470 | Sponsor: Oncternal Therapeutics, Inc | "Based on initial pharmacokinetic results, two additional dosing cohorts with twice daily (BID) oral dosing of ONCT-534 had been incorporated in the Phase 1/2 study ONCT-534-101 (NCT05917470). Overall, fifteen patients received ONCT-534 once daily (QD) in six dosing cohorts and six patients received ONCT-534 BID in two dosing cohorts. Based on a data cut off of September 30, 2024, the BID dosing schedule was well tolerated, with no related Grade 3 or higher toxicities. One patient, who experienced a rising PSA on ONCT-534 at 160 mg BID, had a subsequent 50% reduction in PSA after four weeks of ONCT-534 at 300 mg BID, and at the same time the CAT Scan showed a 16% reduction in target lesions compared to baseline....CTC analysis also showed that some patients who did not respond to ONCT-534 had prostate cancer that had developed neuroendocrine features, which are associated with AR independent disease."
