ORIC® Pharmaceuticals Announces ORIC-944 Preclinical Presentation at the 2025 American Association for Cancer Research (AACR) Annual Meeting
Rhea-AI Summary
ORIC Pharmaceuticals (Nasdaq: ORIC) announced that preclinical data for ORIC-944, their PRC2 inhibitor for prostate cancer treatment, will be presented at the 2025 AACR Annual Meeting in Chicago (April 25-30, 2025).
The preclinical results show ORIC-944 as a potent, selective, and orally bioavailable allosteric PRC2 inhibitor with properties supporting once-daily dosing. The drug demonstrated robust PRC2 inhibition in prostate cancer models, enhancing luminal cell state and increasing androgen receptor (AR) signaling. The treatment restricts cellular plasticity and creates an AR-dependent state, showing synergy with AR pathway inhibitors (ARPIs) in both ARPI-sensitive and resistant settings.
A phase 1b trial combining ORIC-944 with ARPIs is currently ongoing in metastatic prostate cancer (NCT05413421).
Positive
- Phase 1b clinical trial ongoing for ORIC-944 in metastatic prostate cancer
- Demonstrated synergistic effects with AR pathway inhibitors in both ARPI-sensitive and resistant settings
- Drug properties support convenient once-daily dosing regimen
Negative
- Still in early clinical development phase with only preclinical data available
- Efficacy in human subjects yet to be demonstrated

Abstract Highlights
ORIC-944 is a potent, highly selective, orally bioavailable, allosteric inhibitor of PRC2 that demonstrates best-in-class drug properties, including potency, solubility, and pharmacokinetics, with half-life supporting once daily dosing. In preclinical prostate cancer models, ORIC-944 demonstrated robust inhibition of PRC2, enhanced luminal cell state, and increased androgen receptor (AR) signaling. Analysis of chromatin revealed that ORIC-944 specifically restricts accessibility to lineage-associated transcription factors known to impart cellular plasticity in prostate cancer. This plasticity-restricted luminal state conferred by PRC2 inhibition is dependent on AR, leading to antitumor activity either in the hormone-depleted context or in the combination setting with an AR pathway inhibitor (ARPI). Together these data indicate that ORIC-944 reinforces a luminal cell state and, notably, restricts access to plasticity genes leading to a highly AR-dependent state in prostate models. This mechanism supports the observed preclinical synergy between PRC2 inhibition and ARPIs in both ARPI-sensitive and ARPI-resistant settings. These results position ORIC-944 as a potential best-in-class PRC2 inhibitor that blocks prostate tumor adaptation, restores luminal features, and sensitizes tumors to ARPIs. A phase 1b trial of ORIC-944 in combination with ARPIs is ongoing in metastatic prostate cancer (NCT05413421).
