"2025 was an important year of progress for Eikon’s business and clinical programs," said Roger M. Perlmutter, M.D., Ph.D., Chief Executive Officer and Board Chair of Eikon. "With our initial public offering, and the consequent strengthening of our balance sheet, we believe we are well-positioned to advance multiple registration-enabling programs, bringing us closer to our mission of delivering breakthrough therapeutics to patients with serious illnesses."

Pipeline Updates

The following paragraphs describe progress made in advancing Eikon’s clinical programs through the end of 2025.

EIK1001 is a systemically administered dual-agonist of Toll-like receptors 7 and 8 designed to stimulate both innate and adaptive immune responses. Phase 1 studies have previously shown that EIK1001 exhibits single-agent activity in patients with advanced malignancy. This mechanism may complement the antitumor immune response engendered by PD-(L)1 blockade. Updates include:

Enrollment was completed in the TeLuRide-005 Phase 2 study evaluating the use of EIK1001 in combination with pembrolizumab and histology-appropriate chemotherapy for the first-line treatment of non-small cell lung cancer. The company expects a comprehensive data set to become available in 2H 2026.

EIK1003 & EIK1004 are next-generation, highly-selective PARP1 inhibitors that have been observed to leave PARP2 signaling intact. PARP2 inhibition may be a key driver of the hematological toxicity associated with first generation, non-selective PARP inhibitors. Updates include:

EIK1003 is under evaluation in a Phase 1/2 trial as monotherapy and in combination with hormonal blockade (prostate cancer) or chemotherapy (breast or ovarian cancer) to establish the feasibility of combination-based approaches.
Initiation of Cohort 1D, combining EIK1003 with platinum and paclitaxel therapy in breast and ovarian cancer treatment is anticipated in 2H 2026.
EIK1004, a highly-selective PARP1 inhibitor differentiated by its ability to cross the blood-brain barrier, is being evaluated in a Phase 1/2 trial in advanced solid tumors in patients with or without active brain metastases.

EIK1005 is a WRN helicase inhibitor with demonstrated in vitro activity in MSI-high cancer cells. EIK1005 was optimized using Eikon’s technology platform, which includes its imaging instruments that permit single molecule tracking in living cells. Updates include:

An abstract describing the pre-clinical characterization of EIK1005 was accepted for presentation at 2026 Annual meeting of the American Association for Cancer Research (AACR) (Free AACR Whitepaper).
Successful completion of a healthy volunteer study by year-end 2025 permitted initiation of a Phase 1/2 trial in patients with malignant disease that is now underway.

Board Update
In December 2025, Eikon announced the election of David W. Meline as an independent director. Mr. Meline is the former Chief Financial Officer at Moderna Inc. Prior to Moderna, Mr. Meline served as CFO of Amgen Inc. and 3M Company, and he spent more than 20 years at General Motors Company in a range of finance and management roles.

Fourth Quarter and Full Year 2025 Financial Results

Cash Position: As of December 31, 2025, Eikon had cash, cash equivalents, and marketable securities of $336.0 million. In February 2026, Eikon raised $381.2 million in gross proceeds from an upsized IPO of common stock. Eikon expects its current cash, cash equivalents, and marketable securities, which includes proceeds from its February 2026 IPO, will fund operations into the second half of 2027.

Research and Development ("R&D") expenses: R&D expenses were $65.2 million for the fourth quarter of 2025 compared to $53.9 million for the fourth quarter of 2024, an increase of $11.3 million, or 21%. The increase was primarily due to accelerating clinical trial activity and increased facility and information technology expenses following the move into our new Millbrae, CA headquarters in April 2025. R&D expenses were $250.3 million for the year ended December 31, 2025 compared to $204.5 million for the year ended December 31, 2024, an increase of $45.8 million, or 22%. The increase was primarily due to expansion of our clinical trial activity, increased facility and information technology expenses associated with occupancy our new Millbrae headquarters in April 2025, and compensation costs from headcount growth.

General and Administrative ("G&A") expenses: G&A expenses were $17.9 million for the fourth quarter of 2025 compared to $13.9 million for the fourth quarter of 2024, an increase of $4.0 million, or 29%. The increase was primarily due to higher compensation costs, mainly higher corporate bonuses, and increased depreciation expense following the move into our Millbrae headquarters in April 2025. G&A expenses were $88.6 million for the year ended December 31, 2025, compared to $55.8 million for the year ended December 31, 2024, an increase of $32.8 million, or 59%. This increase was primarily due to the impairment of $21.3 million of assets relating to properties in Hayward, CA and New York, NY that we vacated during the year. An additional primary driver of the increase was compensation costs, mainly from stock option modification charges, higher corporate bonuses, and increased depreciation expense following occupancy of our Millbrae headquarters in April 2025.

Net Loss: Net loss attributable to common stockholders was $79.7 million for the fourth quarter of 2025, as compared to $64.9 million for the prior-year period. For the full year 2025, net loss attributable to common stockholders was $333.6 million as compared to $243.8 million for the full year 2024.
