"We made meaningful progress in the first quarter advancing our oncology programs and expanding the clinical evidence supporting their potential," said Roger M. Perlmutter, M.D., Ph.D., Chief Executive Officer and Board Chair of Eikon Therapeutics. "We are particularly encouraged by the breadth of data emerging across our pipeline, which will be featured at the ASCO (Free ASCO Whitepaper) annual meeting, and we believe these programs are well positioned to address important unmet needs in oncology. With a strong balance sheet, we remain focused on disciplined execution as we advance toward additional clinical milestones this year."
Clinical Updates
Eikon continues to advance its lead programs and reports the following updates through the end of the first quarter of 2026:
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. The program continues to advance across multiple clinical trials in melanoma and non-small cell lung cancer ("NSCLC"). Three abstracts have been accepted for presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) ("ASCO") annual meeting, including an updated data set from a now fully enrolled Phase 2 trial evaluating EIK1001 in combination with pembrolizumab and chemotherapy for NSCLC. The updated data set includes a full interim data readout of the non-squamous cohort and a partial interim data readout of the squamous cohort. In addition, we expect to make a Trial-in-Progress presentation to highlight an ongoing Phase 2/3 trial of EIK1001 in combination with pembrolizumab for advanced melanoma, as well as the initiation of a Phase 2/3 trial in combination with pembrolizumab and chemotherapy for stage 4 NSCLC.
EIK1003 is a next-generation, highly selective PARP1 inhibitor that has 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. The program is advancing through an ongoing Phase 1/2 trial in patients with breast, ovarian, prostate, or pancreatic cancer. An abstract has been accepted for presentation at the ASCO (Free ASCO Whitepaper) annual meeting, including updated data from Cohort 1A evaluating EIK1003 as a monotherapy and Cohort 1C evaluating EIK1003 in combination with paclitaxel in patients with platinum-resistant ovarian cancer, or breast cancer patients who are either Her-2 negative, ER+, and hormonal therapy-experienced, or ER- and chemotherapy-experienced. The dose escalation portion of the trial has been completed for Cohorts 1A, 1B (in prostate cancer patients in combination with the novel hormonal agent, abiraterone, and prednisone), and 1C, with backfill nearing completion. Separately, the first patient has been dosed in a Phase 2 dose optimization trial. In addition, global site selection has been initiated for Cohort 1D, which will evaluate EIK1003 in combination with paclitaxel and platinum-based chemotherapeutic agents in patients with breast or ovarian cancer.
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. The program has advanced into clinical development, with a Phase 1/2 trial underway in patients with advanced solid tumors, which began dosing in February 2026. Two abstracts have been accepted for presentation or publication at the ASCO (Free ASCO Whitepaper) annual meeting, including data on pharmacokinetics and pharmacodynamics in healthy volunteers and resulting dose modeling, as well as a Trial-in-Progress presentation for the ongoing Phase 1/2 trial.
First Quarter 2026 Financial Results
Cash Position: As of March 31, 2026, Eikon had cash, cash equivalents, and marketable securities of $596.0 million. Eikon expects its current cash, cash equivalents, and marketable securities, to fund operations into the second half of 2027.
Research and Development ("R&D") expenses: R&D expenses were $70.0 million for the first quarter of 2026 compared to $56.6 million for the first quarter of 2025, an increase of $13.5 million, or 24%. The increase was primarily due to accelerating clinical trial activity and a $5.0 million milestone payment to Impact Therapeutics (Shanghai) Inc. in the first quarter of 2026 for advancement of EIK1003 into Phase 2 development.
General and Administrative ("G&A") expenses: G&A expenses were $17.3 million for the first quarter of 2026 compared to $14.8 million for the first quarter of 2025, an increase of $2.5 million, or 17%. The increase was primarily due to higher depreciation expense following the occupation of Eikon’s Millbrae headquarters in April 2025 and higher professional fees, insurance expenses, and recruitment fees.
Net Loss: Net loss attributable to common stockholders was $83.0 million for the first quarter of 2026, as compared to $74.5 million for the prior-year period.
