ORIC expects to initiate single agent clinical trial in an undisclosed tumor type in 2H21
ORIC-533 IND filing is the first of three IND/CTA filings expected in 2021
SOUTH SAN FRANCISCO, Calif. and SAN DIEGO, June 28, 2021 (GLOBE NEWSWIRE) -- ORIC Pharmaceuticals, Inc. (Nasdaq: ORIC), a clinical stage oncology company focused on developing treatments that address mechanisms of therapeutic resistance, today announced that the U.S. Food and Drug Administration (FDA) has cleared the company’s Investigational New Drug Application (IND) for ORIC-533 to proceed into a first-in-human clinical trial. ORIC-533 is a highly potent, 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.
“The FDA clearance of our IND application for ORIC-533 is a significant milestone for ORIC as we move into the clinic with a second novel, internally discovered oncology drug candidate,” said Jacob Chacko, M.D., president and chief executive officer. “In preclinical studies, ORIC-533 has demonstrated higher potency within a high AMP environment compared to all CD73 and adenosine receptor inhibitors against which it was compared. Furthermore, in addition to the potential best-in-class properties of ORIC-533, we are excited about its differentiated clinical development plan that will explore its single agent activity in contrast to the combination studies that dominate the CD73 field today.”
Based on a preclinical collaboration with an academic key opinion leader that generated compelling single agent activity in patient derived model systems in an undisclosed tumor type, the company plans to pursue a single agent clinical development plan in this indication. ORIC plans to initiate the Phase 1 clinical trial with ORIC-533 in the second half of 2021 to evaluate safety, PK and preliminary efficacy in cancer patients.
This is the first of three planned IND/CTA filings for 2021, with the IND filing for ORIC-944 and CTA filing for ORIC-114 expected in the second half of the year.
ORIC-533 is a highly potent, 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. ORIC-533 has demonstrated greater potency in preclinical studies compared to an antibody approach, other small molecule CD73 inhibitors and inhibitors of adenosine receptors. Preclinical data suggest ORIC-533 binds CD73 with high affinity and effectively blocks adenosine-driven immunosuppression in a high AMP environment. In preclinical studies, nanomolar concentrations of ORIC-533 efficiently rescued cytotoxic T-cell function in the presence of high AMP concentrations, reflective of AMP levels observed in tumors.
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, and follow us on Twitter or LinkedIn.
