Press release from Companies
Published: 2026-05-25 14:45:54
Double Bond Pharmaceutical International AB (publ) (“DBP”) today announces that a scientific abstract based on final clinical data from the company's extensive Real-World Evidence (RWE) study of Temodex has been submitted for review to the scientific committee of the Society for Neuro-Oncology (SNO), ahead of the annual meeting in Philadelphia, USA.
The abstract presents the final results of a retrospective cohort study encompassing a total of 375 patients who underwent surgical resection for malignant primary brain tumors. The purpose of the study was to evaluate the clinical efficacy of adding the company's local chemotherapy, Temodex, to the standardized surgical workflow.
Final Clinical Endpoints and Statistical Significance
The completed analysis of the study population demonstrates a confirmed and enhanced therapeutic benefit for patients who received Temodex as an adjunct to standard of care (SoC), compared to the control group that received SoC alone:
The finalized dataset reinforces the clinical efficacy and demonstrates a more pronounced survival difference than initially indicated by the preliminary calculations. The detailed analysis also includes subgroup stratifications based on histological and molecular markers, which have previously been submitted for presentation at the EANS2026 Congress in Hamburg.
Technical Background and Translational Relevance for SI-053
Temodex has been used clinically for over a decade in selected regions and serves as the technical prototype for DBP's global drug candidate SI-053. SI-053 is a further developed, locally acting formulation of temozolomide that has been granted Orphan Drug Designation by the European Medicines Agency (EMA).
These final RWE data establish a verified clinical baseline for the technology ahead of upcoming prospective clinical trials in Europe.
“The submission of these final results to SNO in Philadelphia marks an important step in the company's international development strategy,” says Igor Lokot, CEO of Double Bond Pharmaceutical. “SNO is the largest multidisciplinary neuro-oncology forum in the world and a central venue for presenting our latest clinical outcomes. Disseminating our data at this meeting is essential to ensure maximum international reach and impact for our research findings.”
