VANCOUVER, BC / ACCESS Newswire / April 21, 2026 / Onco-Innovations Limited (CBOE CA:ONCO)(OTCQB:ONNVF)(Frankfurt:W1H, WKN: A3EKSZ) ("Onco" or the "Company") announces the successful completion of a significant milestone with Dalton Pharma Services ("Dalton"), focused on analytical method development for purity determination of Intermediate 1 (monomer) of its proprietary polymer platform supporting ONC010. The completed work includes development of a robust reverse-phase high-performance liquid chromatography (RP-HPLC) analytical method designed to support impurity detection and quality control of the monomer used in the Company's nanoparticle-based drug delivery system. Pre-validation data generated during the program demonstrated strong analytical performance, including high sensitivity for impurity detection at low thresholds, excellent linearity across the tested range, and consistent chromatographic behavior suitable for routine analytical application.
Dalton's development program supports the establishment of a fit-for-purpose method for use in ongoing development and future GMP manufacturing activities. The method will form the basis for formal analytical test procedures as part of the Company's broader chemistry, manufacturing, and controls (CMC) program. Process development for the monomer has been completed, with successful isolation of intermediary scale-up batches at approximately 20 grams and 181 grams, each achieving high purity levels of not less than 98% as confirmed by HPLC analysis. These results support the reproducibility and scalability of the monomer synthesis process.
"Completion of this analytical method development program represents an important step forward in strengthening the quality and control framework for our polymer platform," said Dr. Islam Mohamed, Chief Medical Officer of Onco-Innovations. "Establishing reliable and sensitive analytical methods is critical to supporting reproducible manufacturing and advancing our program toward IND-enabling studies and clinical development."
Additional process improvements have been implemented, including refinement of synthesis conditions and impurity control strategies through optimized purification techniques. The Company continues to define final quality specifications for the polymer and associated intermediates as part of its ongoing CMC development program.
