MILLBRAE, Calif., Aug. 11, 2026 (GLOBE NEWSWIRE) -- Eikon Therapeutics, Inc. (NASDAQ:EIKN) (Eikon), a late-stage clinical biopharmaceutical company dedicated to developing innovative medicines to address serious unmet medical needs, today announced the selection of a dose of 0.60 mg/m² that will be employed in future for all patients randomized to receive EIK1001 in the TeLuRide-006 trial. This decision aligns with a recommendation from an independent DMC following a prespecified analysis of unblinded data.

"To date, despite multiple combination clinical studies, statistically significant improvement in overall survival in the treatment of advanced melanoma has not been achieved over checkpoint inhibitor monotherapy," said Roy Baynes, M.D., Ph.D., Chief Medical Officer of Eikon. "EIK1001’s activation of both myeloid and plasmacytoid dendritic cells to stimulate both innate and adaptive immunity, bringing a broader répertoire of immune cells to target tumor cells, represents both an orthogonal mechanism and an agent with monotherapy activity. These criteria merit study in combination with checkpoint inhibitors. The selection of an optimized dose for this trial advances our efforts to bring this approach to patients in urgent need of better therapies."

About EIK1001 (TLR7 and 8 Dual Agonist)

EIK1001 is an investigational, systemically administered dual-agonist of Toll-like receptors 7 and 8 designed to stimulate both innate and adaptive immune responses to malignancy. In Phase 1 trials of EIK1001, single-agent activity was observed in patients with advanced solid tumors. This mechanism may complement the antitumor immune response engendered by PD-(L)1 blockade.

About TeLuRide-006

TeLuRide-006 (NCT06697301) is a global, multicenter, randomized, double-blind, adaptive Phase 2/3 registrational trial of EIK1001 or placebo, in combination with pembrolizumab, as first-line therapy for participants with advanced cutaneous melanoma.

About Melanoma

Cutaneous melanoma is the most common form of melanoma and the fifth most common cancer diagnosed in the United States, with rates of diagnosis more than doubling over the past 30 years. Advanced cutaneous melanoma is the most aggressive type of skin cancer, characterized by spread beyond the primary lesion to regional lymph nodes or distant organs, and has variable rates of treatment response. Immunotherapy and targeted therapies have been shown to inhibit tumor growth, but responses are heterogeneous and patients often develop resistance.
