"2025 was a transformational year for ORIC highlighted by clinical data that further demonstrated the potential best-in-class profiles of rinzimetostat in prostate cancer and enozertinib in lung cancer," said Jacob M. Chacko, M.D., president and chief executive officer. "Those data, along with substantially extended cash runway, position us well for 2026 and beyond as we advance our programs towards registrational studies."

2025 Key Accomplishments

Rinzimetostat: a potent and selective allosteric inhibitor of PRC2

Completed Phase 1b dose exploration in prostate cancer and selected provisional recommended Phase 2 doses (RP2Ds) of rinzimetostat to be tested in combination with the approved doses of darolutamide and apalutamide in dose optimization.
Reported potential best-in-class efficacy and safety dose exploration data in combination with darolutamide and with apalutamide in patients with metastatic castration-resistant prostate cancer (mCRPC). Data demonstrated:
PSA responses and ctDNA reductions across all rinzimetostat dose levels and at comparable rates in combination with apalutamide or with darolutamide.
Broad and deep PSA responses that compare favorably to competitor PRC2 inhibitors, with 55% of patients (11/20) achieving a PSA50 response (confirmed in 40%), and 20% of patients (4/20) achieving a PSA90 response (all confirmed).
Rapid and deep ctDNA responses across a breadth of AR mutations and other gene alterations, with 76% (13/17) achieving > 50% ctDNA reduction, and 59% (10/17) achieving ctDNA clearance, which is greater than clearance rates observed in precedent trials with standard of care agents in comparable mCRPC patient populations.
Both combination regimens demonstrated a clearly differentiated safety profile compatible with long-term dosing, with the vast majority of treatment-related adverse events (TRAEs) Grade 1 or 2 in severity and consistent with PRC2 and AR inhibition.
Presented preclinical data at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Symposium on Molecular Targets and Cancer Therapeutics demonstrating potential utility of rinzimetostat combined with AR inhibition in castration-sensitive prostate cancer and combined with KRAS inhibition in KRAS G12C-mutant NSCLC and colorectal cancer models.
Enozertinib: a brain-penetrant inhibitor that selectively targets EGFR exon 20 and EGFR PACC mutations

Reported potential best-in-class efficacy and safety data from a Phase 1b trial of enozertinib at the ESMO (Free ESMO Whitepaper) Asia Congress 2025 in NSCLC patients with EGFR exon 20 and EGFR PACC mutations. Data demonstrated:
Systemic activity in 2L EGFR exon 20 and pretreated EGFR PACC exceeding competitor benchmarks.
Highly competitive preliminary 1L systemic activity, with 67% ORR in EGFR exon 20 and 80% ORR in EGFR PACC.
Convincing 1L CNS activity, with 100% intracranial ORR in EGFR exon 20 and 100% intracranial ORR in EGFR PACC in patients with measurable CNS disease, including in patients with active brain metastases.
Competitive safety profile, with no significant off-target toxicity, resulting in low rate of treatment discontinuations.
Announced a clinical trial collaboration and supply agreement with Johnson & Johnson to evaluate enozertinib in combination with amivantamab and hyaluronidase-lpuj subcutaneous injection (SC amivantamab) for the 1L treatment of NSCLC patients with EGFR exon 20 mutations.
Announced publication in Cancer Research of preclinical data demonstrating enozertinib’s exquisite selectivity, strong potency, brain penetrance, and antitumor activity across a broad range of EGFR exon 20 and PACC mutant models.
Anticipated Program Milestones:

ORIC anticipates the following upcoming milestones:

Rinzimetostat in mCRPC:
1Q 2026: Combination dose optimization data with AR inhibitor
1H 2026: Initiate first global Phase 3 registrational trial in mCRPC
2H 2026: Program update
Enozertinib in NSCLC:
2H 2026: 1L EGFR exon 20 monotherapy data and combination data with SC amivantamab
2H 2026: 1L EGFR PACC monotherapy data
Fourth Quarter and Full Year 2025 Financial Results

Cash, Cash Equivalents and Investments: Cash, cash equivalents and investments totaled $392.3 million as of December 31, 2025, which includes net proceeds of $124.4 million from a private placement financing in May 2025 and $117.6 million from the company’s ATM program in 2025. Subsequent to the quarter ended December 31, 2025, the company raised an additional $20.0 million in net proceeds from a healthcare specialist fund under the ATM program resulting in proforma cash and investments of $412.3 million as of December 31, 2025. The company expects its cash and investments to fund the current operating plan into 2H 2028.

R&D Expenses: Research and development (R&D) expenses were $25.9 million for the three months ended December 31, 2025, compared to $32.0 million for the three months ended December 31, 2024, a decrease of $6.1 million. For the year ended December 31, 2025, R&D expenses were $109.8 million compared to $114.1 million for the same period in 2024, a decrease of $4.3 million. The decreases were due to lower rinzimetostat drug manufacturing costs and lower costs from discontinued programs, offset by higher personnel costs, including additional non-cash stock-based compensation, and costs related to the advancement of enozertinib.

G&A Expenses: General and administrative (G&A) expenses were $8.7 million for the three months ended December 31, 2025, compared to $7.6 million for the three months ended December 31, 2024, an increase of $1.1 million. For the year ended December 31, 2025, G&A expenses were $33.2 million compared to $28.8 million for the same period in 2024, an increase of $4.4 million. The increases were primarily due to higher personnel costs and professional services, including additional non-cash stock-based compensation.
