"We continue to make steady progress in advancing our pipeline of novel oncology candidates," said Jacob M. Chacko, MD, chief executive officer, "We expect to report initial data from our three ongoing studies in the first half of 2023, which includes our Phase 1b single agent trials for ORIC-533, our orally bioavailable CD73 inhibitor, ORIC-114, our brain penetrant EGFR/HER2 inhibitor, and ORIC-944, our embryonic ectoderm development (EED) inhibitor."
First Quarter 2022 and Other Recent Highlights
Preclinical Data Presented at AACR (Free AACR Whitepaper): In April 2022, ORIC disclosed new preclinical data in three poster presentations and one oral presentation at the 2022 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting.
ORIC-533: Oral Small Molecule CD73 Inhibitor
ORIC-533 is a highly potent, orally bioavailable small molecule inhibitor of CD73 that has demonstrated more potent adenosine inhibition in preclinical studies compared to an antibody approach and other small molecule inhibitors of the adenosine pathway. In preclinical studies, ORIC-533 overcame immune suppression and triggered significant lysis and cell death of multiple myeloma cells in an assay comprised of autologous bone marrow microenvironment. A Phase 1b trial with ORIC-533 as a single agent in multiple myeloma is enrolling patients, and the company expects to report initial Phase 1b data from this trial in the first half of 2023.
ORIC-114: EGFR/HER2 Inhibitor
ORIC-114 is a brain penetrant, orally bioavailable, irreversible inhibitor designed to selectively target EGFR and HER2 with high potency against exon 20 insertion mutations. In preclinical studies, ORIC-114 achieved tumor regressions in an EGFR exon 20 NSCLC model with superior efficacy relative to CLN-081 and demonstrated greater anti-tumor activity compared to mobocertinib (TAK-788) in an intracranial NSCLC model. A Phase 1b trial with ORIC-114 as a
single agent is enrolling patients with advanced solid tumors with EGFR or HER2 exon 20 alterations or HER2 amplification and allows for patients with CNS metastases that are either treated or untreated but asymptomatic. The company expects to report initial Phase 1b data from this trial in the first half of 2023.
ORIC-944: PRC2 Inhibitor
ORIC-944 is a potent and selective allosteric inhibitor of polycomb repressive complex 2 (PRC2) that targets its regulatory embryonic ectoderm development (EED) subunit and has demonstrated single agent efficacy in multiple enzalutamide-resistant prostate cancer models in preclinical studies. A Phase 1b trial with ORIC-944 as a single agent is enrolling patients with metastatic prostate cancer, and the company expects to report initial Phase 1b data from this trial in the first half of 2023.
PLK4 Inhibitor Program
In March, the company announced a small molecule therapeutic program intended to address a mechanism of innate resistance found in a subset of breast cancers, specifically a synthetic lethal interaction of polo-like kinase 4 (PLK4) inhibition in tumors bearing a TRIM37 DNA amplification. ORIC discovered novel, potent, orally bioavailable small molecule inhibitors of PLK4 that are highly selective and achieved strong anti-tumor activity of TRIM37 high xenograft tumors, with corresponding pharmacodynamic effects and no body weight loss. The PLK4 inhibitor program is currently in lead optimization.
Anticipated Program Milestones
ORIC anticipates the following upcoming milestones:
•ORIC-533: Initial Phase 1b data in 1H 2023
•ORIC-114: Initial Phase 1b data in 1H 2023
•ORIC-944: Initial Phase 1b data in 1H 2023
First Quarter 2022 Financial Results
Cash, Cash Equivalents and Investments: Cash, cash equivalents and investments totaled $256.2 million as of March 31, 2022, which the company expects will fund its current operating plan into the second half of 2024.
R&D Expenses: Research and development (R&D) expenses were $16.8 million for the three months ended March 31, 2022, compared to $11.7 million for the same period in 2021, an increase of $5.1 million. The increase was primarily driven by an increase in external expenses related to the advancement of ORIC-533, ORIC-114, ORIC-944 and our other product candidates of $4.6 million, offset by a decrease in ORIC-101 costs of $0.7 million due to the discontinuation of the program in the first quarter of 2022. Higher internal expenses related to higher personnel costs, including additional non-cash stock-based compensation of $0.5 million, also contributed to the increase in research and development expenses.
G&A Expenses: General and administrative (G&A) expenses were $6.4 million for the three months ended March 31, 2022, compared to $4.9 million for the same period in 2021, an increase of $1.6 million. The increase was primarily due to higher personnel costs, including additional non-cash stock-based compensation of $0.7 million.
