ExpreS2ion Biotechnologies: First Patient Dosed in Phase 1 Clinical Trial of ES2B-C001

By Michael FriisHead of Equities
ExpreS2ion Biotech Holding

ExpreS2ion today announced that the first patient has been dosed with ES2B-C001, and the treatment was well tolerated. This successful dosing marks the transition of the trial from the enrollment phase to the treatment phase. The primary endpoint of the study is to evaluate safety, tolerability, and the maximum tolerated dose. The secondary endpoints include assessing the immunological response and signs of clinical efficacy, such as tumor size reduction.

In today’s announcement, the company also confirmed the timeline (Q3 2025) for a potential response to the amendment. This amendment is intended to support patient enrollment further by enabling the evaluation of the breast cancer vaccine candidate, ES2B-C001, in combination with antibody-drug conjugates (ADCs) and expanding the number of study sites.

At the Q1 2025 results presentation, the CEO stated that the company is still on track to potentially receive preliminary outcomes before the end of this year, with further results expected in 2026. With an anticipated 40-48 weeks to interim data, this timeline remains feasible.
