SOUTH SAN FRANCISCO, Calif. and SAN DIEGO, April 28, 2025 (GLOBE NEWSWIRE) -- ORIC Pharmaceuticals, Inc. (Nasdaq: ORIC), a clinical stage oncology company focused on developing treatments that address mechanisms of therapeutic resistance, today announced the presentation of a poster at the 2025 American Association for Cancer Research (AACR) Annual Meeting, highlighting preclinical data on ORIC-944, a potent, highly selective, orally bioavailable allosteric inhibitor of PRC2, which demonstrated synergistic activity and improved progression-free survival (PFS) when combined with androgen receptor pathway inhibitors (ARPIs) in models of prostate cancer.
'We are excited by the potential of ORIC-944 to be a best-in-class PRC2 inhibitor for the treatment of prostate cancer,' said Lori Friedman, PhD, chief scientific officer. 'The data presented at AACR demonstrate the strong synergy of ORIC-944 when combined with standards of care, reversing the evolution of prostate cancer, and improving progression-free survival in both castration-resistant and castration-sensitive prostate cancer models - validating the clinical exploration of ORIC-944 across the continuum of prostate cancer.'
Poster presentation:
ORIC-944, a PRC2 inhibitor with best-in-class properties, restores luminal features and restricts adaptation in prostate cancer models, conferring synergy with AR pathway inhibitors
Key findings of the presentation:
ORIC-944 increased progression-free survival (PFS) when combined with ARPIs in both castration-sensitive and castration-resistant prostate cancer models.
ORIC-944 demonstrated transcriptional synergy and antitumor synergy when combined with ARPIs in prostate cancer cells.
In preclinical prostate cancer models, ORIC-944 demonstrated robust inhibition of PRC2, enhanced luminal cell state, and consistently restricted lineage transcription factor accessibility through chromatin remodeling, ​thereby reenforcing the luminal state and preventing access to plasticity programs.
Results position ORIC-944 as a potential best-in-class PRC2 inhibitor that, through both transcriptional and chromatin mechanisms, blocks prostate tumor adaptation, restores luminal features, and sensitizes tumors to ARPIs.
ORIC-944 is currently being evaluated in combination with ERLEADA® (apalutamide) and in combination with NUBEQA® (darolutamide) in an ongoing Phase 1b trial for prostate cancer.
About ORIC-944ORIC-944 is a potent and selective allosteric inhibitor of the polycomb repressive complex 2 (PRC2) via the embryonic ectoderm development (EED) subunit that demonstrates best-in-class drug properties in preclinical studies, including potency, solubility, and pharmacokinetics, with half-life supporting once daily dosing. ORIC-944 was initially evaluated as a single agent in a Phase 1b trial in patients with advanced prostate cancer and demonstrated potential best-in-class drug properties, including clinical half-life of approximately 20 hours, robust target engagement and a favorable safety profile. ORIC-944 is currently being evaluated in combination with ERLEADA® (apalutamide) and in combination with NUBEQA® (darolutamide) in an ongoing Phase 1b trial for prostate cancer (NCT05413421).
