ORIC Pharmaceuticals Presents Posters on Four Programs at the 2021 American Association for Cancer Research (AACR) Annual Meeting


SOUTH SAN FRANCISCO and SAN DIEGO, April 12, 2021 (GLOBE NEWSWIRE) -- ORIC Pharmaceuticals, Inc. (Nasdaq: ORIC), a clinical stage oncology company focused on developing treatments that address mechanisms of resistance in cancer, presented four preclinical poster presentations at the 2021 American Association for Cancer Research (AACR) virtual annual meeting.

ORIC-101: Glucocorticoid Receptor (GR) AntagonistORIC-101 is a potent and selective GR antagonist, with two distinct mechanisms of action being evaluated in two Phase 1b trials in combination with: (1) Abraxane (nab-paclitaxel) in advanced or metastatic solid tumors and (2) Xtandi (enzalutamide) in metastatic prostate cancer.

Key findings of the presentation:

  • GR upregulation and activation, an established resistance mechanism for antiandrogens, may drive resistance when antiandrogens are combined with AKT inhibitors.
  • ORIC-101 was able to overcome this resistance and restore antitumor activity in preclinical prostate cancer cell lines.

Poster Presentation:

ORIC-533: CD73 InhibitorORIC-533 is a highly potent, orally bioavailable CD73 inhibitor and has demonstrated greater potency in preclinical studies compared to an antibody approach and other small molecule CD73 inhibitors.

Key findings of the presentation:

  • Nanomolar concentrations of ORIC-533 efficiently rescued cytotoxic T-cell function in the presence of high AMP concentrations, reflective of levels observed in tumors.
  • Inhibitors of adenosine receptors A2A or A2A/B were only able to rescue CD8+ T-cell function in the context of low micromolar AMP, thus may be ineffective in tumors with moderate or high AMP and adenosine levels.
  • ORIC-533 has potential best-in-class properties in reversing immunosuppression in tumors.

Poster Presentation:

ORIC-944: PRC2 Inhibitor  ORIC-944 is a potent and selective allosteric inhibitor of polycomb repressive complex 2 (PRC2) and targets its regulatory embryonic ectoderm development (EED) subunit.

Key findings of the presentation:

  • ORIC-944 has potential best-in-class drug properties compared to first generation PRC2 inhibitors, including a clean CYP profile.
  • ORIC-944 demonstrated superior activity compared to an EZH2 inhibitor in an in vivo DLBCL model.
  • ORIC-944 demonstrated strong tumor growth inhibition as a single agent with once daily dosing in both enzalutamide-responsive and enzalutamide-resistant in vivo prostate cancer models.

Poster Presentation:

ORIC-114: EGFR/HER2 InhibitorORIC-114 is a brain penetrant, orally bioavailable, irreversible inhibitor designed to selectively target EGFR and HER2 with high potency against exon 20 insertion mutations.

Key findings of the presentation:

  • ORIC-114 is highly selective for the EGFR family of receptors with superior kinome selectivity compared to other exon 20 inhibitors.
  • ORIC-114 demonstrated low nanomolar potency across exon 20 insertion variants in biochemical and cell-based assays.  
  • Significant tumor regression was observed in multiple EGFR exon 20 patient-derived xenograft models using once daily oral administration of ORIC-114.
  • ORIC-114 displayed superior brain exposure relative to other compounds targeting exon 20 insertion mutations, and greater activity compared to other EGFR inhibitors in an intracranial NSCLC EGFR mutant xenograft model.

About ORIC Pharmaceuticals, Inc.

ORIC Pharmaceuticals is a clinical stage biopharmaceutical company dedicated to improving patients’ lives by Overcoming Resistance In Cancer. ORIC’s lead product candidate, ORIC-101, is a potent and selective small molecule antagonist of the glucocorticoid receptor, which has been linked to resistance to multiple classes of cancer therapeutics across a variety of solid tumors. ORIC-101 is currently in two separate Phase 1b trials in combination with (1) Abraxane (nab-paclitaxel) in advanced or metastatic solid tumors and (2) Xtandi (enzalutamide) in metastatic prostate cancer. ORIC’s other product candidates include (1) ORIC-533, an orally bioavailable small molecule inhibitor of CD73, a key node in the adenosine pathway believed to play a central role in resistance to chemotherapy- and immunotherapy-based treatment regimens, (2) ORIC-944, an allosteric inhibitor of the polycomb repressive complex 2 (PRC2) via the EED subunit, being developed for prostate cancer, and (3) ORIC-114, a brain penetrant inhibitor designed to selectively target EGFR and HER2 with high potency against exon 20 insertion mutations, being developed across multiple genetically defined cancers. Beyond these four product candidates, ORIC is also developing multiple precision medicines targeting other hallmark cancer resistance mechanisms. ORIC has offices in South San Francisco and San Diego, California. For more information, please go to www.oricpharma.com.
